The Results of Your Labor and a Thank You, by Ray Beckerman, Esq.
Sunday, March 04 2007 @ 04:37 AM EST

The online community now has an opportunity to see the fruits of its labor. Back in December, the Slashdot ("What Questions Would You Ask an RIAA "Expert"?") and Groklaw ("Another Lawyer Would Like to Pick Your Brain, Please") communities were asked for their input on possible questions to pose to the RIAA's "expert", Dr. Doug Jacobson of Iowa State University, who was scheduled to be deposed in February in UMG v. Lindor, for the first time in any RIAA case. Ms. Lindor's lawyers were flooded with about 1400 responses.

The deposition of Dr. Jacobson went forward on February 23, 2007, and the transcript is now available online (pdf). Ray Beckerman, one of Ms. Lindor's attorneys, had this comment: "We are deeply grateful to the community for reviewing our request, for giving us thoughts and ideas, and for reviewing other readers' responses.

Now I ask the tech community to review this all-important transcript, and bear witness to the shoddy "investigation" and 'junk science' upon which the RIAA has based its litigation war against the people. The computer scientists among you will be astounded that the RIAA has been permitted to burden our court system with cases based upon such arrant and careless nonsense."

Here is the deposition as text.

7



1 Jacobson

2 Lack of foundation.

3 A. I don't -- since I'm not on the

5 particular client buys the product.

6 Q. Have you been quoted in press

7 releases issued by the company as to reasons to buy

8 the product?

9 A. Yes.

10 Q. And in those press releases have you

13 A. I very well could have. I do not --

14 without seeing one of the press releases.

15 Q. Is one of the reasons to buy these

16 products to avoid copyright infringement lawsuits?

18 A. That would be a reason to buy one of

19 the products.

21 lawsuits by the RIAA as one of the types of lawsuits

22 that they could avoid by buying these products?

23 A. To my recollection, I have not.

21 2004, marked for identification, as of this

22 date.)

24 A. Steven Brown, what was his title? He

25 was our marketing individual at Palisade. I don't




10



1 Jacobson

2 remember his exact title.

3 Q. Was he authorized to speak for

4 Palisade Systems to the press?

5 A. Yes.

6 Q. I direct you to the fifth paragraph

7 and ask you whether that is an accurate statement of

8 something that was said by Steven Brown.

9 MR. GABRIEL: Objection. Lack of

10 foundation.

11 A. I have no way of knowing firsthand

12 that Steven Brown said that.

13 Q. Do you agree with the statement "Some

14 P2P applications can evade certain security tools"?

15 A. Yes.

16 Q. Do you agree with the statement of

20 faced by organizations associated with file

21 sharing"?

22 MR. GABRIEL: Objection to form.

23 Lack of foundation.

24 A. Can you repeat the question?

25 (Record read.)




11



1 Jacobson

2 A. Since I'm not a lawyer, I'm not sure

3 I can comment on being a liability and the absolute

4 elimination of it.

5 Q. I call your attention to the ninth

6 paragraph, starting with the word "instead."

7 A. Okay.

8 Q. Do you agree with that paragraph?

9 MR. GABRIEL: Objection to form.

10 Lack of foundation.

11 A. Yes, I would agree with that.

12 MR. BECKERMAN: I would like to

13 mark as Exhibit 4 an article dated

14 April 21, 2004, of C/net News.Com.,

15 entitled "New Tool Designed to Block Song

16 Swaps."

17 (Defendant's Exhibit 4, C/net

18 News.com article dated April 21, 2004,

19 marked for identification, as of this date.)

20 Q. Do you agree with the statement in

21 the second paragraph, the first paragraph that's not

22 in bold, which says that the song filtering software

23 is backed strongly by the Recording Industry

24 Association of America, RIAA?

25 MR. GABRIEL: Objection to form.




12



1 Jacobson

2 Lack of foundation.

3 A. I have no firsthand knowledge of

4 whether or not the RIAA has strongly backed Audible

5 Magic software.

6 Q. Do you have any reason to believe

7 that they have?

8 MR. GABRIEL: Object to the form.

9 A. Could you rephrase the question?

10 Q. What is the problem with the

11 question?

12 A. Restate the question and then I will

13 tell you.

14 Q. You said you had no firsthand

15 knowledge. Now I am asking you whether you have any

16 reason to believe that the RIAA did, in fact, back

17 the software strongly.

18 A. I have no firsthand knowledge that

19 they have.

20 Q. Did you ever see this article?

21 A. I don't recall seeing the article on

22 the web.

23 Q. Did you see any articles or press

24 releases saying that the RIAA backed the software

25 strongly?




13



1 Jacobson

2 A. I don't recall seeing any.

3 Q. So this is the first you've heard of

4 it? Is that your testimony?

5 MR. GABRIEL: I object to the form.

6 He said what he said.

7 A. I have no firsthand knowledge that

8 they have strongly backed -- I don't have any

9 firsthand knowledge that they strongly backed the

10 software, Audible Magic software.

11 Q. Do you have any other knowledge that

12 they backed it?

13 A. Not to my recollection.

14 Q. Going down to the second paragraph

15 that's not in bold and the sentences which purport

16 to quote you, would you tell me whether those are

17 accurate quotes.

18 A. Yeah.

19 Q. Now, going down to the fourth

20 paragraph starting with the word "during," is it

21 your testimony that you have no knowledge of RIAA

22 executives helping to guide Audible Magic CEO Vance

23 Ikezoye around federal government offices advocating

24 the song blocking technology as a tool for stopping

25 copyright infringement on file swapping networks?




14



1 Jacobson

2 MR. GABRIEL: Object to the form of

3 the question.

4 A. Could you please read the question

5 back again.

6 (Record read.)

7 A. I have no knowledge that that took

8 place.

9 Q. What is the relationship, if any,

10 between the RIAA and Palisade Systems, Inc.?

11 A. There is no relationship.

12 Q. Has Palisade Systems, Inc. had any

13 dealings with any agents of the Recording Industry

14 Association of America?

15 A. I believe that our chief operating

16 officer had discussions with the RIAA back in the

17 early 2000s.

18 MR. BECKERMAN: I would like to

19 mark as Exhibit 5 a press release from

20 ZDNet entitled "File-Swap Killer Grabs

21 Attention."

22 (Defendant's Exhibit 5, press release

23 from ZDNet entitled "File-Swap Killer Grabs

24 Attention," marked for identification, as of

25 this date.)




15



1 Jacobson

2 Q. Do you know what ZDNet is?

3 A. Yeah.

4 Q. What is ZDNet?

5 A. It is an online publication, is my

6 understanding.

7 Q. Have you ever used ZDNet for anything

8 other than reading?

9 A. Personally, not to my knowledge I

10 haven't.

11 Q. You've never downloaded any software

12 from ZDNet?

13 A. Not that I can recall.

14 Q. Have you never heard of ZDNet as a

15 source of software?

16 A. Not that I recall.

17 Q. And what is ZDNet News?

18 A. My understanding is it's an online

19 publication that I believe they send out to e-mails

20 to the subscribers.

21 Q. Have you ever had any dealings with

22 the University of Rochester?

23 A. Define the university.

24 Q. Excuse me?

25 A. I don't quite understand when you say




16



1 Jacobson

2 the university.

3 Q. Have you ever had any dealings with

4 officials of the University of Rochester?

5 A. Personally I have not, no.

6 Q. Has Palisade Systems?

7 A. Personally I have no knowledge of

8 that.

9 Q. What do you mean personally you have

10 no knowledge of that? Do you have some other kind

11 of secondhand knowledge of it?

12 A. Not that I recall, but I do not keep

13 close tabs of what the marketing or the sales force

14 does.

15 Q. Has Palisade Systems had any dealings

16 with the University of Rochester?

17 A. Not that I recall.

18 Q. Did the provost of the University of

19 Rochester attend a demonstration of the Audible

20 Magic software at RIAA headquarters in January of

21 2004?

22 A. Not that I know of, but ...

23 Q. Do you agree or disagree with the

24 statement that the RIAA has helped the company,

25 meaning Audible Magic, gain entree to official




17



1 Jacobson

2 Washington circles?

3 MR. GABRIEL: Object to form. Lack

4 of foundation.

5 A. I have no knowledge of what the RIAA

6 has done to help Audible Magic.

7 Q. Is it a fact that Audible Magic

8 entered into a cross-licensing agreement with

9 Palisade Systems, Inc.?

10 A. That's correct.

11 Q. What was the software designed to do?

12 A. What software?

13 Q. Song filtering software created by

14 Audible Magic, software that was mentioned in the

15 press releases I just showed you.

16 A. Audible Magic's software is designed

17 to examine audio data and determine if it matches a

18 database of copyrighted materials.

19 MR. BECKERMAN: Would you read back

20 the question.

21 (Record read.)

22 Q. Do you feel you have answered that

23 question?

24 A. I answered the question of what

25 Audible Magic software was designed to do.




18



1 Jacobson

2 Q. Is it song filtering software?

3 MR. GABRIEL: Object to the form.

4 A. Define what you mean by filtering.

5 Q. What is filtering? Withdrawn.

6 Is it your testimony here under oath

7 you do not know what the word "filtering" means?

8 MR. GABRIEL: Object to the form.

9 Argumentative.

10 A. The term has many different uses.

11 I'm trying to --

12 Q. Is the audio designed by Audible

13 Magic designed for song filtering?

14 MR. GABRIEL: Object to the form.

15 Lack of foundation.

16 A. Will you repeat the question.

17 (Record read.)

18 A. I can't testify to what their design

19 team chose to design their software to do.

20 Q. So is it your testimony that you do

21 not know if this software has any application to

22 blocking song trades on peer-to-peer file sharing

23 networks?

24 MR. GABRIEL: Object to the form.

25 That's a different question.




19



1 Jacobson

2 You can answer the question.

3 A. Which application?

4 Q. The same one we've just been talking

5 about. The application designed by Audible Magic,

6 which was cross-licensed to Palisade Systems.

7 A. The Audible Magic code that was

8 licensed by Palisade does not block traffic.

9 Q. What does it do?

10 A. It identifies traffic content.

11 Q. Is it able to identify song files?

12 A. It is able to identify -- it is able

13 to identify --

14 It is able to analyze files and

15 determine if those files match the signatures that

16 are stored in their database.

17 Q. And was it marketed by Palisade

18 Systems as something that could identify and stop

19 illegal file trades in real time without any

20 requirement for individual users to be identified?

21 A. Yes, their code coupled with our

22 code.

23 Q. And was it marketed by Palisade

24 Systems as something that could block specific

25 illegal file trades?




20



1 Jacobson

2 A. Yes.

3 Q. Now, you are the chief technology

4 officer of Palisade?

5 A. That's correct.

6 Q. So you would be knowledgeable about

7 technology work between your company and Audible

8 Magic, is that not true?

9 MR. GABRIEL: Object to the form.

10 A. Define what you mean by technology

11 work.

12 Q. Development of computer programs.

13 A. I am knowledgeable as to how our

14 software operates and how the application interfaced

15 between our software and Audible Magic software

16 operates.

17 Q. Did your company work jointly with

18 Audible Magic to develop the first network

19 appliances that identified copyrighted works on the

20 fly combined with the ability to block individual

21 trades?

22 A. Our company worked with Audible Magic

23 to develop a product to stop peer-to-peer traffic as

24 identified by Audible Magic's proprietary code.

25 Q. And you are testifying here today




21



1 Jacobson

2 that you have no idea how the RIAA reacted to this

3 work that you are doing?

4 A. That's correct.

5 Q. Have the press releases issued by

6 Palisade Systems referred to the RIAA?

7 MR. GABRIEL: I object to the form.

8 Lack of foundation.

9 A. I'm sure that some of our press

10 releases have probably mentioned the RIAA.

11 Q. In what capacity?

12 MR. GABRIEL: Same objections.

13 A. I don't recall any direct quotes out

14 of any of the press releases.

15 Q. Did you ever meet with the CEO of

16 Audible Magic?

17 A. I recall meeting him in just a short

18 meeting when he visited Palisade, but I was not part

19 of the negotiations.

20 Q. Did you discuss the software?

21 MR. GABRIEL: The question is

22 whether Dr. Jacobson talked to the CEO

23 about the software? I'm just clarifying

24 the question.

25 Q. Did you discuss the software?




22



1 Jacobson

2 MR. GABRIEL: I object to the form.

3 A. I can't recall whether I did or

4 didn't.

5 Q. Have you formed an opinion as to

6 whether Marie Lindor personally uploaded any

7 copyrighted files to anyone?

8 A. The computer whose IP address has

9 been identified as being registered to Ms. Lindor

10 has been shown to have made songs available,

11 copyrighted material available to the internet

12 community through peer-to-peer software.

13 MO MR. BECKERMAN: I move to strike the

14 answer as nonresponsive.

15 Would you read back the question.

16 (Record read.)

17 MR. GABRIEL: Is there a question

18 pending?

19 MR. BECKERMAN: Yes. I'm waiting

20 for an answer to the question. It calls

21 for a "yes" or "no" answer.

22 MR. GABRIEL: I object. It does

23 not. He answered the question.

24 MR. BECKERMAN: Are you directing

25 him not to answer the question?




23



1 Jacobson

2 MR. GABRIEL: No, no.

3 THE WITNESS: Would you repeat the

4 question.

5 (Record read.)

6 MR. GABRIEL: My objection was he

7 just answered.

8 You can answer it again.

9 A. Again, the computer registered to

10 Marie Lindor had made available songs through

11 peer-to-peer software, therefore making them

12 available.

13 MR. BECKERMAN: I am going to say

14 this once and I am not going to repeat it.

15 We are here, we have a limited

16 time. I am on page 1 of about 40 pages

17 of notes. If this kind of gamesmanship

18 is going to be continued, we will never

19 get through even a fraction of this

20 deposition and we will just have to

21 continue it. But I have no intention of

22 accepting that type of answer.

23 If that's the way you are going

24 to play this, then we will be here all

25 day. It calls for a "yes" or "no"




24



1 Jacobson

2 answer and there is no reason to be

3 playing games in answering a question

4 that was not asked. He will be asked

5 questions that may relate to what his

6 answer was, but he has not answered the

7 question that was asked of him and it

8 calls for a "yes" or "no" and I expect

9 an answer to it.

10 MR. GABRIEL: It is a nice speech,

11 Ray. The witness answered the question.

12 I object to the characterization of

13 gamesmanship. Because you don't like the

14 answer doesn't mean it is gamesmanship.

15 The witness has answered, he has his

16 opinions. And if you want to argue with

17 me or the witness, we will be here all day

18 or we will leave.

19 MR. BECKERMAN: I am going to ask

20 the question one more time and if I do not

21 get an answer to it, we will eventually

22 seek a ruling on that and we are going to

23 seek a ruling on all questions that we do

24 not receive answers to, all questions to

25 which we do not receive answers to, and




25



1 Jacobson

2 then we will have a continued deposition.

3 MR. GABRIEL: You reserve whatever

4 you want, Ray, and seek whatever rulings

5 you want. The witness answered the

6 question and I submit this is browbeating

7 the witness into trying to get the witness

8 by arguing with me. This is not serving

9 any purpose.

10 BY MR. BECKERMAN:

11 RL Q. Have you formed an opinion as to

12 whether Marie Lindor personally uploaded any

13 copyrighted files, "yes" or "no"?

14 MR. GABRIEL: Objection. Form.

15 Asked and answered twice.

16 Q. Dr. Jacobson, would you please answer

17 the question.

18 A. I have twice already answered the

19 question.

20 Q. Are you refusing to answer the

21 question?

22 MR. GABRIEL: Objection.

23 Argumentative. He answered the question.

24 MR. BECKERMAN: We will seek a

25 ruling on that.




26



1 Jacobson

2 RL Q. Have you personally formed an opinion

3 as to whether Marie Lindor personally downloaded any

4 copyrighted files?

5 A. The computer whose IP address who has

6 been identified as belonging to Marie Lindor made

7 copyrighted material available through peer-to-peer

8 software -- made the material available through

9 peer-to-peer software.

10 MR. BECKERMAN: We also will seek a

11 ruling on that and we will seek a ruling

12 on all follow-up questions which would

13 have resulted from a "yes" or "no" answer.

14 MO I move to strike the nonresponsive

15 answer that was given.

16 Q. Based upon your examination of the

17 hard drive which you examined, what evidence did you

18 find that inculpated Marie Lindor personally?

19 MR. GABRIEL: Object to the form.

20 Lack of foundation.

21 A. Would you please define the

22 second-to-last word.

23 Q. "Her"?

24 A. No, "inculpated." Would you please

25 define that for me.




27



1 Jacobson

2 Q. Do you not know what the word

3 "inculpated" means?

4 A. That's correct.

5 Q. Are you familiar with the word

6 "exculpate"?

7 A. No.

8 Q. What is your educational background?

9 A. Computer engineering.

10 Q. Well, which school did you attend?

11 Did you get a Bachelor's degree?

12 A. Yes.

13 Q. What school?

14 A. Iowa State University, science and

15 technology.

16 Q. When did you graduate?

17 A. With which degree?

18 Q. When did you get your Bachelor's

19 degree?

20 A. 1980.

21 Q. Do you have any other degrees?

22 A. I hold a Master of Science in

23 electrical engineering.

24 Q. When did you get that?

25 A. 1982.




28



1 Jacobson

2 Q. Any other degrees?

3 A. A Doctor of Philosophy, Ph.D., in

4 computer engineering.

5 Q. When was that?

6 A. 1985.

7 Q. And you are associate professor at

8 Iowa State University?

9 A. That is correct.

10 Q. And you do not know what the word

11 "exculpate" means?

12 A. That's correct.

13 Q. Based upon your examination of the

14 hard drive which you examined in this case, what

15 evidence did you find that supported or would

16 support a conclusion that Marie Lindor had

17 personally uploaded any files?

18 A. The hard drive that I examined showed

19 no evidence of any peer-to-peer software or MP3

20 music files.

21 Q. So is it correct to say that there

22 was nothing on the hard drive that tended to prove

23 that she had uploaded or downloaded anything?

24 A. There was nothing on the hard drive

25 that indicated there was any peer-to-peer software.




29



1 Jacobson

2 Q. Hypothetically, had you discovered

3 KaZaA software and song files or remnants of KaZaA

4 software or song files resembling those that had

5 appeared in a screen shot, would that have tended to

6 support a finding that she had downloaded or

7 uploaded copyrighted files?

8 A. That would have supported a claim

9 that that computer was used to make files available.

10 Q. So it would have supported a finding

11 that the computer whose hard drive you examined had

12 been used for that purpose?

13 A. Correct.

14 Q. It would not have supported a

15 finding, would it, as to whether Marie Lindor

16 herself had used those programs or files?

17 MR. GABRIEL: Object to the form.

18 Lack of foundation.

19 THE WITNESS: Please read it back.

20 (Record read.)

21 A. That's correct.

22 Q. Hypothetically, had you discovered

23 substantial deletions, would that have supported a

24 finding that there had been the use of KaZaA file

25 sharing to download or upload copyrighted files?




30



1 Jacobson

2 MR. GABRIEL: Object to the form.

3 Lack of foundation.

4 A. Had I found substantial deletions of

5 the KaZaA software and music files, that would have

6 supported it.

7 Q. Had you discovered that the hard

8 drive had been entirely reformatted would that, in

9 your view, have supported a finding that the

10 computer had been used for uploading or downloading

11 copyrighted works?

12 MR. GABRIEL: Same objections.

13 A. Had the computer been reformatted,

14 there would have been no conclusion that I could

15 have drawn as to what was on the computer prior to

16 formatting.

17 Q. Hypothetically, had you discovered

18 substantial defragmentation of the hard drive, would

19 that have supported a finding that the computer had

20 been used to upload or download copyrighted works?

21 MR. GABRIEL: Same objection.

22 A. If that's all I had found, no, that

23 would not have supported.

24 Q. So you have concluded that the hard

25 drive that you examined was not used for KaZaA file




31



1 Jacobson

2 sharing; is that correct?

3 A. That's correct, as I testified or as

4 I -- in one of my documents, yes.

5 Q. Are you aware of any evidence of

6 anything that would point to Marie Lindor personally

7 having done something as opposed to any other

8 person?

9 MR. GABRIEL: Objection to the

10 form. Lack of foundation.

11 A. I have examined evidence that shows

12 that the computer registered to the IP address

13 belonging to Marie Lindor was used to share

14 copyrighted material.

15 Q. But other than that, other than the

16 fact that the computer was used, as you say, is

17 there any evidence to show what natural person, what

18 individual was the one who actually did it?

19 A. No.

20 Q. Do you know what processes and

21 procedures MediaSentry employed?

22 A. I do not know the inner works of

23 MediaSentry processes and procedures.

24 Q. Do you know what software they used?

25 A. No.




32



1 Jacobson

2 Q. Do you know if it was well known

3 off-the-shelf software or if it was proprietary

4 software?

5 A. Again, I do not know the inner

6 workings of MediaSentry's operations.

7 Q. Do you know if their software had

8 been peer-reviewed or published or anything like

9 that?

10 A. Not that I'm aware of.

11 Q. Have you ever testified as an expert

12 in a deposition?

13 A. No.

14 Q. Have you ever testified as an expert

15 in a trial?

16 A. No.

17 Q. Have you ever testified as an expert

18 in any other type of proceeding?

19 A. I testified in front of a school

20 board.

21 Q. As an expert?

22 A. Yes.

23 Q. On what subject?

24 A. A teacher was accused of viewing

25 pornography at school.




33



1 Jacobson

2 Q. There was no judge?

3 A. No.

4 Q. There was no arbitrator or judicial

5 type of person conducting it? It was just a school

6 board?

7 A. Yes.

8 Q. Has any judge or jury ever found your

9 methodology to be unreliable?

10 A. I've never been in front of a judge,

11 so no.

12 Q. Has any judge or jury ever found your

13 methodology to be reliable?

14 A. Again, I've never been in front of a

15 judge.

16 Q. Has anyone other than the RIAA ever

17 hired you to do a forensic examination of a hard

18 drive?

19 A. Yes.

20 Q. Who?

21 A. That school board. I'm currently

22 working on a --

23 MR. GABRIEL: Why don't you wait

24 until the ambulance passes.

25 MR. BECKERMAN: I don't think we --




34



1 Jacobson

2 MR. GABRIEL: It may take a while.

3 MR. BECKERMAN: This is New York,

4 Richard. This isn't Denver. We could be

5 here all day.

6 MR. GABRIEL: Just try to keep your

7 voice up.

8 A. I am currently working on two

9 forensic cases that are ongoing. I've done quite a

10 bit of forensic work for law enforcement which I do

11 pro bono.

12 Q. When were you first hired to do

13 forensic work on a hard drive?

14 MR. GABRIEL: Just for

15 clarification, when you say hired, does

16 that include the pro bono work he's

17 talking about?

18 MR. BECKERMAN: Yes.

19 A. On a hard drive, probably in the late

20 '80s.

21 Q. And who was that?

22 A. The Iowa State University. I've done

23 quite a bit of forensic work helping out various

24 individuals at the university.

25 Q. What law enforcement agency hired you




35



1 Jacobson

2 to do a forensic examination of a hard drive?

3 A. Again, I did it with no compensation.

4 I do all my forensic exams for law enforcement

5 through the Iowa State University police department.

6 However, they take in cases from other

7 jurisdictions. I don't always know the jurisdiction

8 that brought the case in.

9 Q. And they have never used you as a

10 witness?

11 A. No. We never -- they've always

12 settled.

13 Q. Apart for doing things for people at

14 Iowa State University how many times have you

15 been -- and apart from the RIAA, how many hard

16 drives have you done forensic examinations of?

17 A. By outside the university, do you

18 also mean outside the Iowa State Police Department?

19 Q. No.

20 A. I maybe misunderstood the question.

21 Can you restate the question or repeat the question?

22 Q. I will restate the question.

23 Apart from your work for the RIAA and

24 your work for people at Iowa State University, how

25 many hard drives have you been hired to do a




36



1 Jacobson

2 forensic examination of?

3 A. Probably half a dozen. It's been

4 over such a long period of time.

5 Q. What software did you use?

6 A. In the latest ones I've been using

7 EnCase.

8 Q. Which edition of EnCase?

9 A. I'm using 5.

10 Q. What did you use before?

11 A. I would use various Hex editors and

12 then -- before it was -- before we had sophisticated

13 software. Sometimes I would write software to

14 recover.

15 Q. When did you start using EnCase 5?

16 A. I don't remember the date that it

17 came out. Prior to that I was using version 4.

18 Q. When did you start using that?

19 A. Probably about three years ago.

20 Q. Has anyone other than the RIAA ever

21 hired you to opine on whether a particular computer

22 had been used for uploading or downloading

23 copyrighted works?

24 A. Copyrighted works?

25 Q. Yes.




37



1 Jacobson

2 A. No.

3 Q. How long have you been using your

4 present method of determining whether a particular

5 computer has been used for uploading or downloading

6 copyrighted works?

7 A. About a year and a half.

8 Q. When did you learn your present

9 method of determining whether a particular computer

10 has been used for uploading or downloading

11 copyrighted works? Or did you develop it yourself?

12 A. Clarification. Are you talking about

13 exams on the hard drives or just the process, the

14 entire process?

15 Q. Well, you have a method, do you not?

16 A. I have a method for examining hard

17 drives and I have a method for reviewing the

18 MediaSentry material.

19 Q. So these are two different things?

20 One isn't tied into the other?

21 A. They are two different processes.

22 Q. Okay. So let's break it down. Your

23 method of --

24 The MediaSentry materials are

25 gathered through the internet?




38



1 Jacobson

2 A. Yeah. MediaSentry gathers the

3 material through the internet.

4 Q. How did you learn your method of

5 interpreting -- withdrawn.

6 Are you able --

7 I am having a little difficulty with

8 this conceptually. You are breaking it down into

9 two separate processes. Is it your testimony that

10 there is a way to detect whether a computer has been

11 used for uploading or downloading copyrighted works

12 without both looking at the MediaSentry material and

13 the hard drive?

14 A. Yes.

15 Q. Let's break it down, then, into two

16 separate things.

17 How did you learn your method of

18 determining from the MediaSentry materials whether a

19 particular computer has been used for uploading or

20 downloading copyrighted works?

21 A. It was a process that I developed.

22 Q. You developed it on your own?

23 A. Yes.

24 Q. How did you learn your method of

25 determining from a hard drive whether a particular




39



1 Jacobson

2 computer has been used for uploading or downloading

3 copyrighted works?

4 A. Well, the forensic examination

5 process I learned through self-study and through the

6 forensic examiner's exam.

7 Q. Now, am I correct that you were doing

8 this for law enforcement before you were a certified

9 forensic examiner?

10 A. That's correct.

11 Q. And when did you become a certified

12 forensic examiner?

13 A. September '04.

14 Q. And why did you become a certified

15 forensic examiner?

16 A. Two reasons. One is to be able to

17 better work with the law enforcement and the other

18 is to help support our university's educational

19 mission, since we teach computer forensics.

20 Q. Wouldn't a third reason be that it

21 might give you standing to testify in a court of law

22 as to your forensic examinations of hard drives?

23 A. That I would tie in with the first

24 reason, to work better with law enforcement.

25 Q. What about your private work for the




40



1 Jacobson

2 recording industry of America?

3 A. I was a certified examiner before I

4 was engaged by the recording industry.

5 Q. Isn't it a fact that you were engaged

6 by the RIAA in 2002?

7 A. It was in September '05.

8 Q. You were not doing any work for them

9 in 2002?

10 A. No. My first work for them was in

11 the fall of 2005. I can't remember my first trip to

12 Kansas City.

13 Q. And you weren't doing any work for

14 them in 2003?

15 A. No.

16 Q. And you weren't doing any work for

17 them in 2004?

18 A. I started working with the law firm

19 in the fall of 2005.

20 MR. BECKERMAN: Off the record.

21 (Discussion off the record.)

22 Q. Has your method of determining from

23 the MediaSentry materials whether a particular

24 computer has been used for uploading or downloading

25 copyrighted works been tested by any testing body?




41



1 Jacobson

2 A. Not that I have submitted.

3 Q. Do you know anyone else that is using

4 your method, other than you?

5 A. Not that I'm aware of.

6 Q. Has your method of determining

7 through the MediaSentry materials whether a

8 particular computer has been used for uploading or

9 downloading copyrighted works been subjected to any

10 form of peer review?

11 A. Not that I'm aware of.

12 Q. Has your method of determining from

13 the MediaSentry materials whether a computer has

14 been used for uploading or downloading copyrighted

15 works been published?

16 A. No.

17 Q. Is there a known rate of error for

18 your method?

19 A. No.

20 Q. Is there a potential rate of error?

21 MR. GABRIEL: Object to the form.

22 A. I guess there is always a potential

23 of an error.

24 Q. Do you know of a rate of error?

25 A. To my process, no.




42



1 Jacobson

2 Q. Are there any standards and controls

3 over what you have done?

4 A. No.

5 Q. Have your methods been generally

6 accepted in the scientific community?

7 A. The process has not been vetted

8 through the scientific community.

9 Q. Have you had communications with

10 MediaSentry?

11 A. Not that I recall.

12 Q. Have MediaSentry's methods been

13 tested by any testing body?

14 A. I don't know.

15 Q. Have MediaSentry's methods been

16 subjected to any form of peer review?

17 A. I don't know.

18 Q. Have MediaSentry's methods been

19 published?

20 A. I don't know.

21 Q. It's a fact, is it not, that

22 MediaSentry's methods are secret?

23 MR. GABRIEL: Objection of lack of

24 foundation.

25 A. I don't know.




43



1 Jacobson

2 Q. Is there a known rate of error for

3 MediaSentry's methods?

4 A. Not that I'm aware of.

5 Q. So when you evaluate the MediaSentry

6 materials you are assuming them to be accurate?

7 A. Yes.

8 Q. Is there a potential rate of error

9 for MediaSentry's methods?

10 MR. GABRIEL: Object to the form.

11 A. There is always a potential for an

12 error.

13 Q. Are there any standards and controls

14 over MediaSentry's methods?

15 A. I don't know.

16 Q. Have MediaSentry's methods been

17 generally accepted in the scientific community?

18 MR. GABRIEL: Object to the form.

19 Lack of foundation.

20 A. Not that I know of.

21 Q. Is MediaSentry peer-regulated?

22 A. Not that I know of.

23 Q. Apart from your work on RIAA

24 litigations against owners of internet access

25 accounts, have you engaged in research on




44



1 Jacobson

2 determining whether specific individual computer

3 users engaged in copyright infringement through

4 peer-to-peer file sharing?

5 MR. GABRIEL: I'm sorry. I lost

6 the question. Could you repeat it,

7 please?

8 Q. Apart from your work on the RIAA

9 cases, have you engaged in any research on methods

10 of determining whether specific individual computer

11 users engaged in copyright infringement through the

12 use of P2P file sharing?

13 A. Yes.

14 Q. And what kind of research was that?

15 A. Obviously there was some research

16 done through Palisade as part of its product rollout

17 dealing with how to identify the individuals within

18 an organization. One of my grad students also

19 worked on the project to identify users of

20 peer-to-peer software, although that was focused

21 more on child pornography than it was copyright

22 material.

23 Q. I would like to leave aside research

24 that may have been done by others. I mean to ask

25 whether you personally have engaged in research.




45



1 Jacobson

2 A. Through Palisade as part of product

3 development.

4 Q. Is that something that is research

5 which is private and proprietary?

6 A. No. The piece I did is no longer

7 used as the technology, so it's not.

8 Q. Was it ever published?

9 A. No. At the time it was proprietary

10 to Palisade.

11 Q. And now it's been replaced by other

12 methods?

13 A. Yes.

14 Q. Apart from your work on the RIAA

15 cases, have you engaged in any research on methods

16 of determining whether specific computer hard drives

17 contained evidence of copyright infringement through

18 peer-to-peer file sharing?

19 A. No.

20 Q. Do any of your three reports -- by

21 "three reports" I'm referring to the April 7th

22 initial report, the December 19th declaration that

23 you signed and the October report which you did not

24 sign. Do any of those three reports discuss the

25 possibility of any alternate explanations other than




46



1 Jacobson

2 copyright infringement?

3 MR. GABRIEL: Object to form to the

4 extent that they speak for themselves.

5 You can answer the question.

6 A. Please read the question. I didn't

7 understand.

8 (Record read.)

9 A. Alternate explanations to?

10 Q. Your conclusions.

11 A. No.

12 I'm sorry. I said, "No."

13 Q. Did any of the three reports discuss

14 any alternate explanations other than KaZaA

15 appearing on a file owned by Marie Lindor?

16 MR. GABRIEL: Object to the form.

17 They speak for themselves.

18 A. What do you mean by KaZaA appearing

19 on a file?

20 Q. I'm sorry, I misspoke. Do any of

21 your three reports discuss the possibility of any

22 alternate explanations other than KaZaA appearing on

23 a computer owned by Marie Lindor?

24 A. No.

25 Q. Are you, as we sit here, capable of




47



1 Jacobson

2 thinking of some alternate explanations?

3 A. Yes.

4 Q. Can you think of any possible

5 infirmities in MediaSentry's methods as we sit here?

6 MR. GABRIEL: Object to form and

7 foundation. I'm sorry.

8 A. I don't have an inner knowledge of

9 their methods so I...

10 Q. Can you think of any possible

11 security vulnerabilities in the computer that was in

12 Marie Lindor's apartment?

13 MR. GABRIEL: Object to form and

14 foundation.

15 A. Repeat the question. Read it back.

16 (Record read.)

17 A. I didn't examine the hard drive that

18 was given to me for security vulnerabilities, so I

19 can't attest to what vulnerabilities may have been

20 present in that hard drive.

21 Q. As we sit here, can you think of any

22 possible security vulnerabilities in the computer

23 that was in Marie Lindor's apartment?

24 MR. GABRIEL: Objection to form.

25 Lack of foundation.




48



1 Jacobson

2 A. Read that back.

3 (Record read.)

4 A. Can you read it one more time.

5 (Record read.)

6 A. I'm sure the possibility exists there

7 were security vulnerabilities. Again, I don't know

8 which ones would apply to that particular computer.

9 Q. And did your report discuss any of

10 those possible security vulnerabilities?

11 A. No.

12 Q. Did you testify at an United States

13 Senate committee in September of 2003?

14 A. Yes.

15 Q. Did you make this statement?

16 "In summer of 2000 we introduced

17 PacketHound which is designed to detect, monitor and

18 block unauthorized peer-to-peer applications."

19 A. That sounds like -- that sounds like

20 a statement I made.

21 Q. Did you make this statement?

22 "There are no effective controls

23 regarding content provided on a peer-to-peer

24 network."

25 A. Again, that sounds like a statement I




49



1 Jacobson

2 made.

3 Q. And did you make this statement?

4 "Both the provider and the requester

5 of the file are not easily detected."

6 A. Again, that sounds like a statement

7 that was in that testimony. I don't have the

8 testimony in front of me, so I ...

9 Q. Did you make this statement?

10 "These technologies are not designed

11 for the home users."

12 A. Again, that sounds like a statement

13 that was in the testimony.

14 Q. Did you make this statement?

15 "This leaves individuals on their own

16 to solve the problems of peer-to-peer networking."

17 A. Again, that sounds like a statement

18 that was in the testimony.

19 Q. Did you make this statement?

20 "Which naturally leaves us to the

21 question, what is the homeowner to do?"

22 A. Again, that sounds like something

23 that was in that testimony.

24 Q. Did you make this statement?

25 "Unlike web filtering, where certain




50



1 Jacobson

2 sites can be blocked and web access can be

3 monitored, peer-to-peer traffic cannot be filtered

4 based on its content. This leaves a home user no

5 choice but to either allow peer-to-peer activity and

6 all of its associated risks or not allow any

7 peer-to-peer applications on their machines."

8 A. Again, that sounds like what was in

9 that testimony.

10 Q. Are you familiar with Steven Gottlieb

11 of the RIAA?

12 A. I've heard the name but that's it.

13 Q. Do you agree with this statement

14 which I will represent to you he made on

15 November 15, 2004 in comments he provided to the

16 Federal Trade Commission?

17 "P2P services often configure their

18 software to share content by default. What users

19 often do not know is that they may be sharing their

20 tax records, financial records, health records,

21 business records, e-mail and other personal and

22 private material."

23 Do you agree with that statement?

24 A. Oh, I'm sorry. Yes.

25 Q. Do you agree with this statement,




51



1 Jacobson

2 which I represent to you was made by Mr. Gottlieb?

3 "As an additional matter P2P software

4 may, upon installation, automatically search a

5 user's entire hard drive for content, files that

6 users have no intention of sharing may end up being

7 offered to the entire P2P network."

8 A. Yes.

9 Q. Do you agree with this statement

10 which I represent to you was made by Mr. Gottlieb?

11 "Continued sharing of personal

12 information is hard to avoid and is facilitated by

13 confusing and complicated instructions for

14 designating shared items."

15 A. Yes.

16 Q. Do you agree with this statement also

17 made by Mr. Gottlieb?

18 "A study by Nathaniel S. Good and

19 Aaron Krekelberg at HP Laboratories showed that the

20 majority of the users were unable to tell what files

21 they were sharing and sometimes incorrectly assumed

22 they were not sharing any files when in fact they

23 were sharing all files on their hard drive.

24 MR. GABRIEL: Object to the form.

25 Lack of foundation.




52



1 Jacobson

2 A. I guess I can't quantify some, most,

3 all. I'm sorry.

4 Q. Are you familiar with the report by

5 Nathaniel Good and Aaron Krekelberg at HP

6 Laboratories?

7 A. No.

8 MR. GABRIEL: When we get to a good

9 stopping point, can we take five? It's

10 been an hour and a half.

11 MR. BECKERMAN: Sure.

12 (Recess taken.)

13 Q. Your reports state your conclusions;

14 is that correct?

15 A. Yes.

16 Q. And they state that your conclusions

17 were based upon --

18 Withdrawn. I shouldn't lump the

19 three together.

20 The April report states that

21 conclusions were based upon the materials that had

22 been provided to you by MediaSentry plus a few other

23 documents; is that correct?

24 A. Yes.

25 Q. Does that report explain how you




53



1 Jacobson

2 formed your conclusions from those documents?

3 A. Not in any detail.

4 Q. How many reports have you issued for

5 the RIAA?

6 A. Maybe 200. I don't know, don't

7 recall the exact count.

8 MR. BECKERMAN: I would like to

9 leave a space in the record for that

10 number.

13 Q. How many of those reports concluded

14 that there was in fact downloading or uploading of

15 plaintiff's copyright files?

16 A. All of the -- yes, all of the

17 reports.

18 Q. How much time did you spend on each

19 report?

20 A. A typical report takes me about 45

21 minutes.

22 Q. And how much time did you spend on

23 the April 2006 report in this case?

24 A. Without seeing the billing records, I

25 can only guess but I think it was 45 minutes.




54



1 Jacobson

2 Q. How much time did you spend preparing

3 the unsigned October report?

4 A. That was -- not that one.

5 I'm sorry. I was pointing to

6 something on your desk. I probably shouldn't do

7 that.

8 MR. GABRIEL: After you looked at

9 the hard drive he is asking about.

10 THE WITNESS: Okay. Thank you.

11 Q. Would you like me to show you a copy?

12 A. No. I just wanted to clarify between

13 the two reports that --

14 Again, without looking at the billing

15 records, I would say probably two to four hours.

16 Q. And how much time did you spend on

17 the December 19th declaration?

18 A. Maybe 15 minutes.

19 Q. If a hard drive had been used for

20 peer-to-peer file sharing with KaZaA, would your

21 forensic inspection have allowed you to see whether

22 a file sharing program had been downloaded or

23 installed?

24 A. If the program was present on the

25 hard drive, a forensic examination would have shown




55



1 Jacobson

2 that.

3 Q. Similarly, if the hard drive had been

4 used for peer-to-peer file sharing with KaZaA, would

5 your forensic inspection have allowed you to see

6 whether there was a shared files folder on the

7 computer?

8 A. Yes.

9 Q. And, again, if the hard drive had

10 been used for peer-to-peer file sharing with KaZaA,

11 would your forensic inspection have shown you

12 whether there were audio files or remnants, or

13 evidence thereof, of the files that MediaSentry had

14 observed?

15 A. Yes.

16 Q. Under those same circumstances, would

17 your forensic inspection have allowed you to see

18 whether a party had attempted to delete file sharing

19 programs or other files?

20 A. Yes.

21 Q. Now, a dynamic IP address is

22 allocated very often for a short period of time; is

23 that not correct?

24 A. It depends how you define "short."

25 Q. Well, you yourself used that




56



1 Jacobson

2 technology, did you not?

3 A. Yes.

4 Q. So what is the shortest it could be?

5 There is no shortest, is there? It could be for a

6 split second?

7 A. A computer can request and release.

8 Q. It could be for hours or it could be

9 for seconds or --

10 A. It could be for days, yes.

11 Q. Would it be possible to have the same

12 dynamic IP address assigned to three people during

13 one minutes?

14 MR. GABRIEL: Object to the form.

15 A. It's possible.

16 Q. Now, the users of a peer-to-peer

17 network often think they are anonymous when they

18 distribute files. Isn't that true?

19 A. In my opinion, a lot of users feel

20 that they are anonymous.

21 Q. In your April 7th report you say that

22 in reality they can be identified using the IP

23 address. Is that not what you said in your report?

24 A. Yes, sir.

25 Q. That's not exactly true, is it?




57



1 Jacobson

2 A. I guess I'm not clear what you mean

3 by that.

4 Q. Well, it's true, is it not, that

5 there can be more than one computer operating under

6 a single IP address?

7 MR. GABRIEL: Object to the form.

8 A. As I talked about it in the report

9 with public IP addresses, in order for the internet

10 to function there can only be -- every public IP

11 address has to be globally unique within that window

12 of time.

13 Q. But there can be more than one

14 computer operating behind that IP address?

15 MR. GABRIEL: Same objection.

16 A. Every -- I don't understand what you

17 are asking. Every device connecting to the public

18 internet has to have a global unique address.

19 Q. And a device doesn't have to be a

20 computer, does it?

21 A. That's correct.

22 Q. It could be a router, correct?

23 A. Yes.

24 Q. It could be a wired router?

25 A. Yes.




58



1 Jacobson

2 Q. It could be a wireless router?

3 A. Yes.

4 Q. And if there is a firewall, under

5 most circumstances no one would know the various

6 computers or devices behind the router, would they?

7 MR. GABRIEL: Object to form.

8 A. It depends on the type of router.

9 Q. Is it possible for more than one

10 device to be operating behind a single IP address?

11 A. Yes.

12 Q. Now, when we get to the devices, some

13 of the devices are computers. Is that not correct?

14 A. Yes.

15 Q. And is it possible for a computer to

16 have more than one user?

17 A. Yes.

18 Q. So, in other words, when a person is

19 engaged in peer-to-peer file sharing, it's not the

20 person that could be identified by an IP address, is

21 it?

22 MR. GABRIEL: Object to the form.

23 Lack of foundation.

24 Q. Isn't it the MAC address that is

25 identified?




59



1 Jacobson

2 MR. GABRIEL: Object to form.

3 A. I don't understand the follow-on

4 statement.

5 Q. Do you know what a MAC address is?

6 A. Yes.

7 Q. Can a router have a MAC address?

8 A. Yes.

9 Q. If I had ten different companies

10 operating behind a router and I had a properly

11 functioning firewall or firewalls, would anybody in

12 the wide network actually know what was behind the

13 router with the properly functioning firewall?

14 MR. GABRIEL: Object to the form.

15 Lack of foundation.

16 A. It's possible to determine who is

17 behind that, so to say that there is no way to know

18 is not true.

19 Q. How could you find out?

20 A. Potentially based on the activity

21 coming out. There is lots of ways that attackers

22 could use to determine what is behind a firewall.

23 Q. But one method to identify that

24 person would not be the IP address. The IP address

25 alone would not tell you that, would it?




60



1 Jacobson

2 A. Would not tell you what?

3 Q. What individual was sharing files.

4 A. By "individual" do you mean

5 flesh-and-blood person?

6 Q. Yes.

7 A. The IP address tells you the identity

8 of the computer.

9 Q. It actually doesn't tell you the

10 identity of the computer. It tells you the identity

11 of the device.

12 A. That's correct.

13 Q. And it doesn't actually tell you the

14 identity of the device. It tells you a MAC address?

15 MR. GABRIEL: Objection to form.

16 A. IP address does not tell you a MAC

17 address.

18 Q. How could it tell you the identity of

19 the device? How would you identify a device other

20 than by a MAC address?

21 A. Every device in the public internet

22 is configured with an IP address.

23 Q. Which would link to what?

24 A. Which links to the device.

25 Q. And how do you identify the device on




61



1 Jacobson

2 the internet?

3 A. Again, every device is identified

4 through its IP address. The MAC address is only

5 valid from one local connection to another.

6 Q. What is the one thing unique about

7 each device?

8 MR. GABRIEL: Object to the form.

9 A. Unique to it or that uniquely tells

10 them apart?

11 Q. That tells them apart.

12 A. On the internet the only requirement

13 for uniqueness is the IP address.

14 Q. So when you say that in reality they

15 can be identified using the IP address, your

16 testimony is that it's not the user that can be

17 identified, it's a computer that can be identified?

18 Is that your testimony?

19 Or is your testimony that it is the

20 computer on the network device that is interfacing

21 with the wide network?

22 A. The IP address identifies the

23 computer or device that is connected to the wide --

24 to the internet.

25 Q. And the device might be a network




62



1 Jacobson

2 card?

3 A. Generally network card doesn't have

4 an IP address. The computer is what has the IP

5 address.

6 Q. The device might be a router?

7 A. That's correct.

8 Q. In that report you said that the IP

9 address of the computer can be captured by a user

10 during a search or file transfer. Now, you don't

11 exactly mean of the computer; you mean of the

12 computer or network device, right?

13 A. In the peer-to-peer file transfer the

14 device running -- the computer running the

15 peer-to-peer software reports its IP address

16 along with -- in addition to that, the IP address of

17 the -- if it is behind a router that separates

18 public and private addresses, then the IP address of

19 the public internet will also be shown.

20 Q. But when you said that the IP address

21 of the computer offering the files for distribution

22 can be captured by a user during a search or file

23 transfer, you didn't really mean the computer. You

24 meant the computer or network device?

25 A. In order for the peer-to-peer




63



1 Jacobson

2 software to work, you have to have the identity of

3 the machine holding the music or holding the data.

4 Q. Even if it's going through a router?

5 You're saying there is more than one IP address

6 going through a router?

7 A. The peer-to-peer software will

8 present an IP address within the data payload of the

9 IP packet.

10 Q. Well, what I'm trying to understand

11 is why in your report, referring to your April

12 report, it seems to me that when you were making

13 general descriptions of the technology involved, you

14 kept saying computer or network device but then when

15 you were coming to your conclusions about the

16 defendant, then you all of a sudden started talking

17 about computers and you left out network devices. I

18 was wondering why.

19 Do you agree with that, what I am

20 saying?

21 A. Yes.

22 Q. Why did you do that? Why did you

23 stop mentioning network devices?

24 A. Because in an examination of

25 MediaSentry data, I concluded that it was a computer




64



1 Jacobson

2 at that IP address.

3 Q. And how did you come to that

4 conclusion?

5 A. Through the MediaSentry traffic

6 captures which shows the IP address of the actual

7 computer and the IP address of the packet in transit

8 across the internet, and those two IP addresses were

9 both public and both matched.

10 Q. What is the document you are

11 referring to for MediaSentry?

12 A. I think it was the download.text file

13 or download log maybe they call it.

14 Q. The log for the user?

15 A. No.

16 MR. GABRIEL: Do you want to go off

17 the record for a minute and find it?

18 MR. BECKERMAN: No. We are on the

19 record.

20 Q. The Marie system log? Lindor, Marie

21 system log?

22 A. No. That's not the system log. It

23 could be the download record.

24 Q. This one (indicating)?

25 A. Yes.




65



1 Jacobson

2 MR. BECKERMAN: I would like to

3 mark as Exhibit 6 a printout of numbered

4 pages 36 to 45.

5 (Defendant's Exhibit 6, printout of

6 numbered pages 36 to 45, marked for

7 identification, as of this date.)

8 Q. So this tells you that there was no

9 router?

10 A. This tells me that there was -- yes.

11 There was no router.

12 Q. How does it tell you that there was

13 no router?

14 A. Through the two --

15 If you look at the second chunk down,

16 you will see the source address at the top and you

17 will see the KaZaA IP address midway through that,

18 and they match and they are both public IP

19 addresses.

20 Q. You said they match?

21 A. Uh-huh. The 141.155.57.198.

22 Q. That's the source?

23 A. And then down below you see the KaZaA

24 IP?

25 Q. Yes.




66



1 Jacobson

2 A. It's those two IP addresses.

3 Q. What does the first number indicate?

4 A. The first number of the IP address?

5 Q. Yes.

6 No. The second line of that chunk

7 that says "source." What does that indicate?

8 A. That is the source address. That is

9 where the packet came from.

10 Q. Now we go down to the next line you

11 referred to, it says "KaZaA IP." What does that

12 refer to?

13 A. That is the IP address that the KaZaA

14 software is running on, the IP address of the

15 computer that the KaZaA software is running on.

16 Q. What is the next line?

17 A. A supernode. That's the supernode

18 that KaZaA is connected to.

19 Q. So, in other words, this went in

20 directly through the supernode? So you are saying

21 this transmission went through the supernode?

22 MR. GABRIEL: Objection to form.

23 A. No. This packet just indicates

24 that -- where the supernode is that KaZaA is talking

25 to. The packet as shown by the second line is the




67



1 Jacobson

2 actual source address of the internet packet.

3 Q. What is the next line, the KaZaA IP?

4 A. Oh.

5 Q. The line down below where you say the

6 two numbers match, what is the meaning of that

7 number?

8 A. Which one? The KaZaA IP?

9 Q. You said it is the same number.

10 A. Right.

11 Q. Where it says "KaZaA IP" and there is

12 the same number.

13 A. As line 2, yes. That is the -- that

14 is the --

15 Q. What is the significance of that

16 line?

17 MR. GABRIEL: Let him ask the

18 question and then you answer. He asked

19 what is the significance of that line.

20 A. Of the line "KaZaA IP"?

21 Q. Yes.

22 A. That is the IP address that the KaZaA

23 software is using.

24 Q. And how is that determined?

25 A. It's determined by the KaZaA software




68



1 Jacobson

2 itself.

3 Q. Why wouldn't those two numbers always

4 be the same?

5 A. In the case of a router as you

6 described earlier that has private addresses on the

7 inside, you will see those numbers be different.

8 Q. So you are saying there can be

9 different IP addresses for different devices behind

10 the router?

11 A. Yes.

12 Q. What does the presence of the

13 supernode line indicate?

14 A. It indicates the supernode, that the

15 KaZaA software is used to perform the searches.

16 Q. So does this indicate that the

17 computer that's referred to on -- whose IP address

18 is referred to on the source line and the KaZaA IP

19 line is not a supernode?

20 A. It indicates that that computer is

21 communicating with that supernode in order to do the

22 searches.

23 Q. And how did MediaSentry determine

24 these numbers?

25 A. Line 2 of that section is the address




69



1 Jacobson

2 that is carried within the data packet as it

3 traverses across the internet. The line that starts

4 "X-KaZaA-IP" is part of the data payload within that

5 packet.

6 Q. And how do you know that? Didn't you

7 say you have never communicated with MediaSentry?

8 A. That's correct.

9 Q. So how do you know that?

10 A. Because I understand how KaZaA

11 operates.

12 Q. And how did you come to understand

13 how KaZaA operates?

14 A. Through researching protocol.

15 Q. Starting when?

16 A. I can't remember the exact date I

17 started researching KaZaA. It was all part of the

18 work Palisade did in the production of PacketHound.

19 Q. Are you familiar with the Ross

20 studies of KaZaA?

21 A. Not offhand.

22 Q. You never read them?

23 A. I don't recall without seeing one.

24 MR. BECKERMAN: I would like to

25 mark as Exhibit 7 a study entitled "The




70



1 Jacobson

2 KaZaA Overlay: A Measurement Study."

3 (Defendant's Exhibit 7, study

4 entitled "The KaZaA Overlay: A Measurement

5 Study," marked for identification, as of

6 this date.)

7 Q. So have you reviewed this report at

8 any time?

9 A. Yes, I have.

10 Q. I direct your attention to Page 17

11 and I call your attention to in the middle of the

12 page a sentence that starts with the words "later

13 versions." The statement says, "Later versions

14 (KMDV 2.0+ and KaZaA-Lite) employ dynamic port

15 numbers to evade firewalls."

16 Do you agree with that statement?

17 MR. GABRIEL: Objection. Lack of

18 foundation.

19 A. Yes.

20 Q. Going down to the end of that

21 paragraph, I will read you the last sentence and ask

22 if you agree with that sentence.

23 "Since the KaZaA port numbers are

24 dynamic, it is very difficult to block KaZaA

25 connections unless a very rigid filtering policy is




71



1 Jacobson

2 employed at the firewall." Do you agree with that

3 statement?

4 MR. GABRIEL: Object to form. Lack

5 of foundation.

6 A. Yes.

7 Q. Now I refer you to the first sentence

8 of the next paragraph.

9 "The reality of today's internet is

10 that a large fraction of peers reside behind NATs."

11 Do you agree with that statement?

12 MR. GABRIEL: Object to form. Lack

13 of foundation.

14 A. I don't have any way to know what

15 fraction.

16 Q. Do you agree that NATs exist?

17 A. Yes.

18 Q. What is a NAT?

19 A. The term stands for network address

20 translator. It is a router that on one side has a

21 public IP address and on the other side maintains or

22 has a set of what I want to refer to as private or

23 sometimes inside IP addresses, which are addresses

24 that are not allowed on the public internet.

25 Q. And do you agree that the existence




72



1 Jacobson

2 of a network address translator makes it difficult

3 to detect the IP address of specific computers

4 behind the router?

5 MR. GABRIEL: Objection to form.

6 Lack of foundation.

7 A. By router do you mean network address

8 translator?

9 Q. Yes.

10 A. Yes.

11 Q. And do you agree that KaZaA has used

12 a connection reversal in order to try to overcome

13 that?

14 MR. GABRIEL: Objection to form.

15 Lack of foundation.

16 A. I agree with the definition that they

17 specify in the article. I've never heard that

18 specific term.

19 MR. BECKERMAN: I would like to

20 mark as Exhibit 8 a one-page chart.

21 (Defendant's Exhibit 8, one-page

22 chart, marked for identification, as of this

23 date.)

24 Q. Can you identify what that displays?

25 MR. GABRIEL: Object to foundation.




73



1 Jacobson

2 He didn't draft it.

3 You can answer the question.

4 A. I don't know the intent of it but it

5 shows, as it's labeled, a cable modem connected to

6 the internet. And it shows a set of IP addresses,

7 all of which are the private -- designated as parts

8 of the private IP address range.

9 Q. Going back to the study, Exhibit 7, I

10 call your attention to Page 21, a paragraph bearing

11 number 7, and I'm going to the last two sentences

12 and I am going to ask if you agree with this

13 statement. "KaZaA uses dynamic port numbers along

14 with" --

15 A. I'm sorry. I am not finding it.

16 Q. Page 21, there is a paragraph number

17 7.

18 A. Okay. I'm sorry.

19 Q. I am asking if you agree with this

20 statement. "KaZaA uses dynamic port numbers along

21 with its hierarchical design to avoid firewall

22 blocking."

23 Do you agree with that?

24 MR. GABRIEL: Objection to form.

25 Lack of foundation.




74



1 Jacobson

2 A. I know KaZaA uses dynamic port

3 numbers. Whether that was the original design

4 intent to avoid firewalls would be a fair

5 assumption.

6 Q. The next sentence, do you agree with

7 that statement ?

8 "Furthermore, it uses connection

9 reversal to allow NATed peers to share files."

10 MR. GABRIEL: Objection to form.

11 Lack of foundation.

12 A. Yes.

13 Q. When you studied KaZaA, did you

14 familiarize yourself with the concept of pollution

15 on KaZaA?

16 A. No.

17 Q. Do you know what pollution is on

18 KaZaA?

19 A. My understanding is it is putting

20 things out into the network KaZaA that either

21 misrepresents the content or for some reason is not

22 what it says to be.

23 MR. BECKERMAN: I will mark this as

24 Exhibit 9. It is a paper entitled

25 "Pollution in P2P File Sharing Systems."




75



1 Jacobson

2 (Defendant's Exhibit 9, paper

3 entitled "Pollution in P2P File Sharing

4 Systems," marked for identification, as of

5 this date.)

6 Q. Going to the first page, the

7 right-hand column, the first full paragraph, the

8 first sentence starts with "One sabotage technique."

9 I will ask if you agree with this statement.

10 MR. GABRIEL: I'm sorry. Where are

11 you?

12 I got it.

13 Q. "One sabotage technique that is

14 particularly prevalent today is that of pollution."

15 Do you agree with that statement?

16 MR. GABRIEL: Objection to form.

17 Lack of foundation.

18 A. I don't have any knowledge that as

19 they define pollution it is prevalent on the

20 peer-to-peer systems.

21 Q. Are you aware that one of

22 MediaSentry's areas of business is pollution?

23 A. No.

24 Q. Are you aware that MediaSentry is in

25 the business of sending out decoy files?




76



1 Jacobson

2 MR. GABRIEL: Objection to form.

3 A. No.

4 MR. GABRIEL: Sorry. Belated

5 objection to the form.

6 Q. Excuse me?

7 A. No.

8 Q. I turn you to the second page, the

9 first full paragraph. About two-thirds of the way

10 down in the paragraph there is a sentence that

11 starts "We will see that." I call your attention to

12 that sentence and ask if you agree with this

13 statement.

14 "We will see that pollution is indeed

15 pervasive with more than 50 percent of the copies of

16 many popular recent songs being polluted in KaZaA

17 today." Do you agree with that?

18 MR. GABRIEL: Objection to form.

19 Lack of foundation.

20 A. I have no way of knowing if that's

21 true or false.

22 Q. So is it your testimony that you are

23 not knowledgeable about pollution?

24 MR. GABRIEL: Objection to form.

25 Q. Are you knowledgeable about




77



1 Jacobson

2 pollution?

3 A. Only to the extent that I know what

4 it is.

5 Q. And that's the sole extent of your

6 knowledge?

7 A. Yes.

8 Q. And are you familiar with the

9 distinction between content pollution and metadata

10 pollution?

11 A. I just now read their classification.

12 Q. Is it the first time you ever learned

13 of the distinction between those two terms?

14 A. Yes.

15 Q. So it would be fair to say that your

16 expertise does not extend to the nature and extent

17 and methods of pollution on KaZaA?

18 A. Yes.

19 Q. When you in your report refer to

20 analogizing an IP address to a return address and a

21 send address on a letter, would you say that analogy

22 is somewhat incorrect?

23 A. There is probably no perfect analogy

24 but it's a reasonable analogy to use for a lay

25 explanation.




78



1 Jacobson

2 Q. Is it fair to say that your postal

3 address is to your home whereas an IP address would

4 be more like an address to a timeshare that you

5 might occupy for a split second or for a minute?

6 MR. GABRIEL: Objection to form.

7 A. The IP address delivers to a device

8 or location.

9 Q. But not a person?

10 A. That's correct.

11 Q. And not for any given amount of time,

12 just as long as the internet connection stays on

13 line?

14 MR. GABRIEL: Objection to form.

15 A. Define what you mean by internet

16 connection.

17 Q. You don't know what I mean by an

18 internet connection?

19 A. There are multiple definitions.

20 Q. Why don't you give me the most common

21 meaning.

22 A. There is an application layer

23 connection which is used by individual applications

24 to communicate.

25 Q. With a dynamic IP address is the




79



1 Jacobson

2 person using it still using it after he's

3 disconnected from the internet?

4 MR. GABRIEL: Objection to form.

5 A. Depending on how they are connected,

6 the dynamic address may be dropped.

7 Q. You're saying they could end their

8 connection to the internet and still -- and the

9 dynamic IP address stays in effect and then if they

10 turn it back on, they could pick up the same exact

11 dynamic IP address? Is that your testimony?

12 MR. GABRIEL: Objection to form.

13 Lack of foundation.

14 A. If the device that issues the dynamic

15 address can detect the other device being turned

16 off, then the dynamic IP address can be released.

17 Otherwise, the dynamic address could still be

18 assigned to that device.

19 Q. Now, with a decentralized

20 peer-to-peer network, it's your statement in your

21 report that a request is sent to each neighbor and

22 each neighbor sends the request to the next neighbor

23 and so on. Did you mean that literally?

24 A. You said decentralized?

25 Q. Yes.




80



1 Jacobson

2 A. Yes.

3 Q. To neighbors? What do you mean by

4 neighbors?

5 A. The decentralized peer-to-peer

6 software referred to the peer-to-peer entities that

7 they talked directly to as neighbors.

8 Q. So you are using it figuratively to

9 describe other computers?

10 A. Yes.

11 Q. You say the semi-decentralized

12 peer-to-peer network uses a central index server.

13 Is that correct?

14 A. Yes.

15 Q. And that if one server node quits,

16 the other nodes can still function?

17 A. Yes.

18 Q. Now, when you access a screen shot,

19 are you accessing a file or are you accessing an

20 index of files?

21 A. When you query the server, what you

22 get is an index of the files.

23 Q. Now, is it your testimony that every

24 time you see a screen shot in KaZaA, you're seeing

25 files that are on a single ordinary node?




81



1 Jacobson

2 MR. GABRIEL: Objection to form.

3 A. There are many ways you can query

4 KaZaA, one of which is to ask all the files that are

5 contained on a particular machine.

6 Q. How would you frame such a query?

7 A. You frame the query with the address

8 of the machine that contains the information.

9 Q. And do you know how MediaSentry

10 queried?

11 A. I don't know the exact techniques

12 that they used.

13 Q. Now you said in your report that you

14 will demonstrate how defendant's internet account

15 and computer were used. Would you now demonstrate

16 for me how you can -- show me how you can

17 demonstrate that the defendant's computer was used?

18 A. Which line of the report are you?

19 Q. What?

20 A. Which line of the report are you

21 referring to?

22 Q. Paragraph 15.

23 A. Would you restate the question.

24 (Record read.)

25 A. Identifications through the IP




82



1 Jacobson

2 address to demonstrate which computer it is.

3 Q. No, I'm asking you to demonstrate it

4 now for me. You said, "I will testify to the

5 procedures and results obtained by MediaSentry

6 coupled with the information complied by defendant's

7 ISP to demonstrate the defendant's internet account

8 and computer were used to download and upload

9 copyrighted music from the internet using the KaZaA

10 peer-to-peer network."

11 Please demonstrate for me that

12 defendant's computer was used to download and upload

13 copyrighted music.

14 A. I can demonstrate through the

15 MediaSentry material.

16 Q. Okay.

17 A. I don't have the MediaSentry

18 material.

19 MR. BECKERMAN: We will mark as

20 Exhibit 10 a two-page printout, page

21 numbers 46 to 47.

22 (Defendant's Exhibit 10, two-page

23 printout of page numbers 46 to 47, marked

24 for identification, as of this date.)

25 MR. BECKERMAN: We will mark as




83



1 Jacobson

2 Exhibit 11 a printout, page numbers 49 to

3 187.

4 (Defendant's Exhibit 11, printout of

5 page numbers 49 to 187, marked for

6 identification, as of this date.)

7 MR. BECKERMAN: And you already

8 have Exhibit 6 and we have Exhibit 12,

9 which is a screen shot, pages 199 to 224.

10 (Defendant's Exhibit 12, printout of

11 pages 199 to 224, marked for identification,

12 as of this date.)

13 MR. BECKERMAN: And we will mark as

14 Exhibit 13 a one-page printout marked as

15 page number 48.

16 (Defendant's Exhibit 13, one-page

17 printout of page numbered 48, marked for

18 identification, as of this date.)

19 MR. BECKERMAN: And we will mark as

20 Exhibit 14 a printout of pages numbers 188

21 through 198.

22 (Defendant's Exhibit 14, printout of

23 pages numbers 188 through 198, marked for

24 identification, as of this date.)

25 Q. Now would you please demonstrate how




84



1 Jacobson

2 you can show that it's the defendant's computer that

3 was used.

4 MR. BECKERMAN: Off the record.

5 (Recess taken.)

6 Q. Please demonstrate that the

7 defendant's computer was used.

8 MR. GABRIEL: If I can ask you, if

9 you refer to an exhibit, please say what

10 the exhibit is.

11 THE WITNESS: Yes.

12 Q. Before we go into that, let me just

13 ask you something.

14 When you say "defendant's computer"

15 in your report, you're referring to the computer

16 that was accessed by MediaSentry; is that correct?

17 A. I'm referring to the -- yeah, the

18 computer with the IP address shown in Exhibit 6 that

19 we discussed earlier.

20 Q. And it's your contention that the

21 computer as to which you examined the hard drive is

22 a different computer than the one that was accessed

23 by MediaSentry; is that correct?

24 A. Yes.

25 Q. Now, going to the first computer, how




85



1 Jacobson

2 do you know that it was defendant's computer?

3 A. We don't have the Verizon information

4 in front of me. By using the subpoenaed records

5 from Verizon they show --

6 Q. They were asked --

7 I'm sorry. I cut you off.

8 They were asked to identify the owner

9 of an account that had used an IP address; is that

10 correct?

11 A. Yes.

12 Q. How would that tell you who owned the

13 computer?

14 A. It tells me the individual who has

15 the account that was associated with that IP

16 address; therefore, that computer at the time.

17 Q. Let's say -- not me, that would be

18 too improbable. Let's say you had a visitor at your

19 home and that visitor plugged into your internet

20 connection with his laptop. Would that make his

21 computer your computer?

22 A. Without knowing the configuration of

23 your home network, I couldn't.

24 Q. Let's say you had a wired internet

25 connection at your home, you had a cable modem and




86



1 Jacobson

2 someone was visiting who had a laptop, a friend of

3 yours or relative, and that person asked if they

4 could plug in their laptop and check their e-mail.

5 Okay?

6 Now, the IP address would show up as

7 your address, would it not? The dynamic IP address?

8 A. It depends.

9 Q. If I sent a query like the record

10 industry sent to Verizon, I would get you, right?

11 If you are the person who pays for the internet

12 access at your home.

13 A. If the ISP allows multiple devices

14 directly connected to their internet service.

15 Q. And it wouldn't have been your

16 computer, it would have been your friend's or

17 relative's computer. Correct?

18 MR. GABRIEL: Object to the form.

19 Lack of foundation.

20 A. The scenario you laid out. If the

21 ISP allowed multiple IP addresses, then it would

22 have associated an IP address with that particular

23 device.

24 Q. So when you say it was defendant's

25 computer, you don't actually have any knowledge as




87



1 Jacobson

2 to whether it was defendant's computer. All you

3 know is that the defendant's name is associated with

4 the internet access account; is that correct?

5 MR. GABRIEL: Objection to form.

6 A. I know that the -- yeah, the computer

7 associated with that user account, an IP address was

8 used.

9 Q. But you don't know whose computer it

10 actually was, do you?

11 A. No.

12 Q. But your report said it was

13 defendant's computer, so I think you will agree that

14 that's an imprecision in your report.

15 MR. GABRIEL: Objection to form.

16 Lack of foundation. Misstates the report.

17 A. The report states that I have

18 identified through the internet service provider the

19 account holder of the IP address.

20 Q. The report says that you will

21 demonstrate that it was defendant's computer that

22 was used. How can you demonstrate that the computer

23 belonged to the defendant? You don't know who it

24 belonged to.

25 MR. GABRIEL: Objection to form.




88



1 Jacobson

2 Lack of foundation.

3 Q. You are under oath.

4 A. It's my opinion that given the

5 information from MediaSentry and from Verizon, that

6 that IP address was associated with the defendant

7 and computers or at least in presence of the

8 defendant.

9 Q. There are two parts to your

10 statement. You say the defendant's internet account

11 and computer. Right now I'm not asking you about

12 the internet account. I'm asking about the

13 computer. You will agree, then, will you not, that

14 when you said computer that you don't actually know

15 if it was defendant's computer or not?

16 A. It is the computer associated with

17 the account of the defendant.

18 Q. But you don't know if it was

19 defendant's computer?

20 A. I know that the computer was

21 associated with the defendant's internet account.

22 Q. But you don't know if the defendant

23 owned it?

24 A. Nowhere is purchase information.

25 Q. And you do not know if the defendant




89



1 Jacobson

2 ever used it?

3 A. I know that the computer associated

4 with that address was used.

5 Q. Now, demonstrate how you know that

6 that computer was used to upload and download

7 copyrighted music from the internet.

8 A. Well, I know which computer through

9 Exhibit 6. That is the primary piece of evidence.

10 I know that material was downloaded

11 through Exhibit 10. I know music was made available

12 through Exhibits 10, 11, 12 and 14, and I know that

13 the music was downloaded through Exhibit 11.

14 MR. BECKERMAN: I would like to

15 mark as Exhibit 15 the undated October

16 report.

17 (Defendant's Exhibit 15, undated

18 October report, marked for identification,

19 as of this date.)

20 Q. When did you provide this report to

21 Mr. Gabriel?

22 A. October 25th.

23 Q. Why did you not sign it?

24 A. It's a draft.

25 Q. Why is it not dated?




90



1 Jacobson

2 A. It was a draft report.

3 Q. Have you ever submitted an unsigned

4 or undated draft to Mr. Gabriel before?

5 A. I could have. I don't recall.

6 Q. Have you ever submitted unsigned

7 drafts or undated drafts to anyone in Mr. Gabriel's

8 firm before?

9 A. Again, I could have. I don't recall.

10 Q. Is it your practice to submit

11 unsigned, undated drafts before submitting your

12 final reports to them?

13 A. The standard report goes in without

14 their review.

15 MR. GABRIEL: I would like the

16 record to reflect that there is a copying

17 issue in Exhibit 15. Page DJ0069 was

18 stamped "Draft." I note in the copying

19 the draft was too light to copy

20 apparently.

21 Q. Did Mr. Gabriel tell you not to issue

22 a final report, but to issue a draft instead?

23 A. Yes.

24 Q. Now, turning to Page DJ0071,

25 Paragraph 17, the second sentence, which says, "I




91



1 Jacobson

2 will testify based on the forensic examination of

3 the hard drive that was copied from the computer

4 owned by the defendant."

5 Now, are you saying there that the

6 second computer which you claim is different than

7 the first one was owned by the defendant also?

8 A. I'm lost in the second, first and --

9 Q. It's your words. It's your

10 testimony. It's your declaration, your unsigned

11 draft which Mr. Gabriel asked you to submit to him

12 so he could have input into the final. But this was

13 your wording I assume. Right?

14 A. Yes.

15 Q. This was wording that was not fed to

16 you by Mr. Gabriel?

17 A. Correct.

18 Q. So you say the computer owned by the

19 defendant. Now you are saying that the second

20 computer was owned by the defendant.

21 A. I'm saying the hard drive that I was

22 given to examine was reported to have been owned by

23 the defendant and I examined that hard drive and

24 came up with that conclusion.

25 Q. So is it your testimony that she




92



1 Jacobson

2 owned both computers?

3 MR. GABRIEL: Objection to form.

4 A. It's my testimony that the hard drive

5 contained no evidence of KaZaA and that hard drive

6 was reported to have belonged to the computer owned

7 by the defendant.

8 Q. What basis do you have for saying

9 that the computer was owned by the defendant?

10 A. Based on the chain of evidence

11 that -- the chain of custody that followed the

12 forensic disk.

13 Q. So it is your testimony that Marie

14 Lindor, who is a home health aide who has never even

15 used a computer, it is your testimony that she owns

16 two computers?

17 MR. GABRIEL: Objection to form.

18 Lack of foundation. Misstates testimony.

19 Q. Is that your testimony? She has

20 never even used a computer in her life, that she

21 owns not one, but two computers?

22 MR. GABRIEL: Same objection.

23 A. What I am stating is that the hard

24 drive I examined, which was reported to have come --

25 been owned by the defendant did not contain KaZaA or




93



1 Jacobson

2 any of the copyrighted or any music files.

3 MR. BECKERMAN: Let's mark as

4 Exhibit 16 your April report.

5 (Defendant's Exhibit 16, Dr. Douglas

6 W. Jacobson's April report, marked for

7 identification, as of this date.)

8 Q. Now, on Page DJ0006, Paragraph 19, in

9 the last line you use the words "being distributed."

10 A. Yes.

11 Q. Were you using "distributed" in the

12 legal sense of the word or in the generic sense of

13 the word?

14 MR. GABRIEL: Objection to form.

15 A. I'm not a lawyer so I don't know the

16 legal -- I guess I am not clear as to what

17 difference you are trying to make between the two

18 words.

19 Q. Where did you get the word

20 "distributed"?

21 A. In that paragraph I'm referring to

22 the fact that the files were on the peer-to-peer

23 network and by the nature of the peer-to-peer

24 network they are being distributed.

25 Q. Do you know of any instances in which




94



1 Jacobson

2 they were distributed to anyone other than

3 MediaSentry?

4 A. Given the nature of the peer-to-peer

5 system, there is a high probability that they

6 were -- well, strike that.

7 Distributed, they are being offered

8 for distribution by the fact that they were on the

9 peer-to-peer network.

10 Q. The question was whether they had

11 actually been distributed, not whether they had been

12 offered for distribution.

13 MR. GABRIEL: Objection to form.

14 A. The KaZaA program made those files

15 available through the supernode. Anybody --

16 Let me strike that and start over.

17 The KaZaA program made the files

18 available on her computer for distribution and given

19 the nature of the peer-to-peer network and the

20 number of users, there is a high probability that

21 songs were actually uploaded from that computer.

22 Q. Do you have any knowledge of any

23 specific instances of any uploads other than to

24 MediaSentry?

25 A. No.




95



1 Jacobson

2 Q. In Paragraph 21 you use the words

3 that the computer was registered to the defendant.

4 How does a computer get registered to a person?

5 A. Through the IP address it is

6 registered. Verizon indicated the subscriber.

7 Q. So you don't mean that the computer

8 was registered to the defendant. You mean the IP

9 address was identified by Verizon as having been on

10 the internet access account that was in the name of

11 the defendant. Is that correct?

12 A. The IP address of, was registered to

13 the defendant on said computer. So it says that the

14 IP address.

15 Q. Not the computer. The IP address was

16 registered?

17 A. That's what 21 states.

18 Q. 21 states that the computer that had

19 the IP address was registered to the defendant.

20 "I will testify based on all of the

21 information" --

22 A. Right, right.

23 Q. So you don't mean the computer was

24 registered, you mean the IP address was registered?

25 A. Yes.




96



1 Jacobson

2 Q. Now, in Paragraph 22 you state that

3 you could prove from the MediaSentry user log that

4 the music found on the defendant's computer was

5 downloaded from other users on the internet. How

6 would you have done that?

7 A. By using the metadata tags, in

8 particular the description tag. For example,

9 Page 0106.

10 MR. GABRIEL: What exhibit?

11 THE WITNESS: I'm sorry.

12 Exhibit 11.

13 A. Page 10106 indicates in the

14 description "ripped by" and had several -- several

15 cases "ripped by X7" and so on, and that's

16 throughout the document.

17 Q. A metadata is text, is it not?

18 A. Yes.

19 Q. Metadata can be changed, can it not?

20 A. Metadata can be changed and is not

21 present on original CD recordings.

22 Q. And it can be changed easily through

23 commonly available software, can it not?

24 A. Yes.

25 Q. And could it be changed through KaZaA




97



1 Jacobson

2 software?

3 A. Yeah. I believe KaZaA lets you edit

4 the metadata.

5 MR. BECKERMAN: I would like to

6 mark as Exhibit 17 a page of handwritten

7 notes.

8 (Defendant's Exhibit 17, page of

9 handwritten notes, marked for

10 identification, as of this date.)

11 Q. When were these notes prepared?

12 A. These notes were prepared prior to

13 the submission of the October -- let's see which

14 exhibit. Exhibit 15.

15 Q. Are there any other notes which you

16 jotted down which you did not preserve from the date

17 the hard drive was furnished to you?

18 A. No.

19 Q. What are the letters at the top

20 right?

21 A. DHCP name server.

22 Q. What are the three IP addresses below

23 that?

24 MR. GABRIEL: Objection to form.

25 A. Those are the IP addresses of the




98



1 Jacobson

2 name server that were on her computer.

3 Q. What does that mean?

4 A. The name server, my best analogy is a

5 giant phone book that converts names and IP

6 addresses. So when you type in www.google.com, you

7 get the IP address of Google.

8 Q. What is the entry at the bottom,

9 "7704 repaired"? What is that a reference to?

10 A. In examining the hard drive, it

11 appeared that there was some type of repair of the

12 Windows operating system on that date.

13 MR. BECKERMAN: I would like to

14 mark as Exhibit 18 a single-page document

15 which says "wireless router" at the top.

16 (Defendant's Exhibit 18, single-page

17 document bearing "wireless router" at the

18 top, marked for identification, as of this

19 date.)

20 Q. When was this prepared?

21 A. 3/14.

22 Q. Now, You say "wireless router?" and

23 then say, "No." How did you know there was no

24 wireless router?

25 A. Again, by looking at the information




99



1 Jacobson

2 on Exhibit 6.

3 Q. How does that show you that there is

4 no wireless router?

5 A. Again, as I testified earlier, here

6 at the source address and that the KaZaA IP address

7 matched.

8 Q. And that tells you that there was no

9 wireless router?

10 A. Again, those are all public IP

11 addresses on both the computer and the device that

12 put the IP packet onto the internet, both at the

13 same IP address.

14 Q. And that's your sole basis for your

15 conclusion?

16 A. Yes.

17 MR. BECKERMAN: I would like to

18 mark as Exhibit 19 a two-page letter from

19 Verizon.

20 (Defendant's Exhibit 19, two-page

21 letter from Verizon, marked for

22 identification, as of this date.)

23 Q. Is that the source for your

24 information as to whose access account it was?

25 A. Yes.




100



1 Jacobson

2 MR. BECKERMAN: I would like to

3 mark as Exhibit 20 a resume, a one-page

4 resume, page number DJ0076.

5 (Defendant's Exhibit 20, one-page

6 resume, page number DJ0076, marked for

7 identification, as of this date.)

8 A. It is a printout of a file that I

9 found on the hard drive that I examined. It was

10 described in Exhibit 15.

11 Q. Did you know who prepared this?

12 A. I know it was on the hard drive and

13 it in the directory of user Kathleen on the system.

14 Q. Do you know who typed it?

15 A. No.

16 Q. Now, what does it say next to the

17 word "e-mail" in this resume?

18 A. J-C-Q-L-L-I-N-E.

19 Q. What tools did you use to determine

20 that the hard drive had not been used for a KaZaA

21 account?

22 A. I used EnCase to examine the captured

23 hard drive.

24 Q. When you used EnCase, did you know

25 that this matter was in litigation and that you were




101



1 Jacobson

2 an expert witness in this case?

3 A. Yes.

4 Q. Did you not have screens? When you

5 used EnCase, didn't you look at a computer screen?

6 A. Yes.

7 Q. Did you save what was on that screen?

8 A. No.

9 Q. Did you generate reports?

10 A. No.

11 Q. Now I'm not asking you if you printed

12 out reports or saved reports. I'm asking you if you

13 generated reports.

14 A. No.

15 Q. So you did not document your findings

16 in EnCase at all, did you?

17 A. No.

18 Q. Did Mr. Gabriel tell you to do that?

19 A. No.

20 Q. So did you feel that you could just

21 review it on EnCase and then come and testify from

22 memory at a trial? Is that what you intended to do?

23 A. I examined the hard drive, found no

24 evidence of file sharing software or audio files,

25 and so there was nothing to document.




102



1 Jacobson

2 Q. S
