Logikcull Webinar: Preventing the #1 Litigation Risk Logikcull.com
Security experts have a favorite saying: data is most vulnerable when it's in motion. Discovery, unfortunately, is a process of motion, where information and documents are shared between client, counsel, third-party service providers and opposing parties. Often, this data is exchanged on physical media (i.e. hard drives, DVDs) or through insecure methods like unencyrpted email. It's a risky, time-consuming and expensive process.
And with ShareSafe from Logikcull, it has been eliminated.

A large gamma ray detector then senses these gamma rays to detect and locate explosives within 10 seconds while penetrating materials like concrete and steel. The system is designed to be low cost, safe for operators, and deployable within 12 months of adequate funding.
This patent describes a method and apparatus for minimizing signal noise in neutron fluorescence processes using synchronized gamma ray detection. The apparatus includes a neutron source, gamma ray detector, and control mechanism. The gamma ray detector is synchronized to the neutron time of flight by the control mechanism, such that it remains switched off during the pulse period of the neutron source and subsequent time of flight. This ensures that any nuisance signals arriving at the detector during these times are not detected or considered. The synchronization of the gamma ray detector improves the signal-to-noise ratio by reducing background noise from sources like the neutron generator and atmosphere.

The phenomenon will only grow larger
with time. 37 billion divices will be Internet
connected by 2020. Thought leaders refer
to this as the “Internet Of Things” [“IOT”]

10. The Net Effect Is That Sensor Data
Is Exploding (cont.)
The legal system has no choice but to incorporate this flood
of sensor data into its practice.
We now truly have the “Internet of Evidence™”

11. The Internet of Evidence Is As Ground
Breaking as Fingerprinting or DNA!
The sensor data and the Internet of Evidence™
support:
Determination of time lines
Identities of actors
Alibis
Intent of actors
External and environmental conditions
Who knew what, and when they knew it

12. The Internet of Evidence Is As Ground
Breaking as Fingerprinting or DNA! (cont.)
Just as with physical evidence, Internet of
Evidence™ is subject to:
Requirements for discovery, seizure, chain of
custody, and accurate transcription
Possible tampering, forgery, and counterfeiting,
and
Intentional or inadvertent
loss or destruction.

13. Case Study Number 1 – The Data
Collection That Didn’t Happen
<Case name withheld at request of subject attorneys>
California Criminal case – molestation of underage
female victims by 17-year-old male, July 2011
A family event with parents, defendant, two younger
brothers, older married sister, two nieces [6 and 8],
and a family friend [11]
Defendant was professionally
employed as a paparazzi
photographer

14. Case Study Number 1 – The Data
Collection That Didn’t Happen (cont.)
While sister [nieces’ mom] went shopping,
Defendant was asked to:
Take paparazzi photos of 3 girls using Canon EOS 60D DSLR
Download music from iTunes to sister’s laptop
“RIP” some music CDs to sister’s laptop
Sister was gone for 45 minutes
Family barbecue went on as planned
11-year-old reported molestation to girlfriend after
starting 7th Grade in September

15. Internet of Evidence™ Involvement
Alibi consisted of testimony that the Defendant was
too busy doing digital tasks to have committed any
crime.
Victim interviews done by male investigator with no
specialized training in this area. Psychological
evidence is not discussed in this Webinar
Zero digital evidence was preserved,
at the discretion of the investigator.
Investigator testified there would be
nothing of value.

16. Internet of Evidence™ Involvement (cont.)
Internet of Evidence™ consisted of:
Laptop hard drive
Time / Date stamps of all relevant files
Non-File Area [NFA] data from potential deleted files
Canon memory card
File system data
Exif header data
iTunes transaction data, with time tags
Potential Internet Service Provider packet data
Potential geo-reference data from any cell phones
Other data?

16
17. Internet of Evidence™ Involvement (cont.)
Analysis should have included:
Reconstruction of activities needed to
achieve the digital results shown by the
evidence
Some potential operations could be
“batched”, but some could not
Potential reconstruction of rooms visited by
the relevant parties

18. Resolution
Trial lasted for about 15 days
14 counts = Life Without Parole, due to age of alleged
victims and multiple victim enhancement
Family split – sister on one side, parents siding with
Defendant
Nieces recanted testimony
Acquittal on 6 charges; Hung jury on 8 charges; DA
deciding whether to re-file
1/11/2016The Internet of Evidence(tm) - Little Brother Is Watching You – And He’s Taking Notes!
18
19. Analysis
What should have been done:
Impound all Internet of Evidence™ data immediately
Create perfect copies using NIJ-approved passive copy apparatus
Subpoena relevant records from Internet Service Provider, iTunes
and/or other vendors
Once Internet of Evidence™ data is secure, THEN determine if
data has probative value [it may not!]
If probative value cannot be ruled out, analyze data using
qualified experts
If no experts on staff, LOOK ON THE INTERNET! There are
specialists all over.

21. Case Study Number 2 – The Text
Message from Who Knows Where
<Case name withheld by request of subject attorneys>
California Criminal contempt case – Wife received text messages
on her cell phone with husband’s cell number as callback, in
violation of no-contact order
Husband is a business owner, wife is a divorce attorney, disputed
custody of 6-year-old daughter
Husband alleged wife knew his cell phone provider password;
she or a co-conspirator could have logged into the web
account and forged husband’s identity in sending of message
Husband took voluntary polygraph test, registered NDI

22. Analysis
Internet of Evidence™ issue: If such a forgery were
perpetrated via a Web login instead of an actual cell
phone, is such a forgery detectable from either the
receiving cell phone or from the web record?
Interestingly, no. Text message formats do not retain
path data [“Envelope data”]].
Cell phone provider records have
envelope data and can be
subpoenaed, but are retained for
only 10 days, and then are erased.
Retrieval actions came TOO LATE.

22
23. Resolution
Text message charge dropped.
What should have been done:
Impound all Internet of Evidence™ data immediately
Create perfect copies using NIJ-approved passive copy
apparatus
Subpoena relevant records from cell phone provider before
destruction date.
THEN analyze to see if data is relevant

24. Summary
The Internet of Evidence™ is potentially as much of a
game changer to civil and criminal jurisprudence as
fingerprinting and DNA analysis were in their day.
Internet of Evidence™ information exists literally
everywhere in many contemporary legal matters
Such data may have profound consequences.
[Of course, such data is not magic, and may not exist
in all cases. And it may not have probative value.]

24
25. Summary (cont’d)
The safest course is to follow the standards for E-Discovery and
evidence in general:
Identify where evidence can possibly be. Time is of the essence
Preserve it - Impound [or at least write-protect] all Internet of
Evidence™ data immediately
Subpoena relevant records from Internet Service Provider and/or
vendors while it is still available
Preserve writeable media such as hard drives from being overwritten
Gather it - Create perfect copies using NIJ-approved passive copy
apparatus
Process it – this might mean forensic recovery or other measures
Review and analyze it to determine what is relevant
Produce it for the Court or for Opposing Counsel, as required

25
26. Summary (cont.)
Once Internet of Evidence™ data is secure, THEN determine if
data has probative value
If probative value cannot be ruled out, analyze data using
qualified experts
If no experts are on staff, LOOK ON THE INTERNET! There are
specialists all over.
The field is so large that no one individual can be an expert on
all areas.
Individual specialists may need to research highly case-specific
questions.
For large or complex cases, one expert may need to function as
a Lead Investigator.

27. Final Words
The Internet of Evidence™ has only recently arrived, but it is
here to stay
There were, literally, ZERO cell phone photos or movies from
inside the Twin Towers. Such devices are now the most
common platforms for watching NFL games, after TV!
When a new fleet of helicopters arrived with an aviation unit
at a base in Iraq, some soldiers sent pictures of the flight line
to some “pretty girls” in Sweden with whom they were
corresponding... From these photos , Al Qaeda operatives
posing as the girls were able to determine the exact
location of the helicopters inside the compound and
conduct a mortar attack, destroying four of the AH-64
Apaches. http://www.army.mil/article/75165/Geotagging_poses_security_risks/

28. Final Words (cont.)
“During Israel’s 2006 war in southern Lebanon with Iranian-
backed… Hezbollah, Iranian SIGINT professionals tracked signals
coming from personal cell phones of Israeli soldiers to identify
assembly points of Israeli troops that may have telegraphed the
points of offensive thrusts into Lebanon.
