First of all, I am grateful to God for establishing me to
complete this seminar report. I am thankful to college for
providing me with all the necessary facilities. I wish to
express my sincere thanks to our Director, Mr. R. K.
Jaiswal for his exemplary encouragement and support. I
would like to express my deepest appreciation to the
Head of Department (CSE), Mr. Alok Mishra, who
continually and convincingly conveyed a spirit of interest
in regard to seminar report
I owe my profound gratitude to our seminar guides, Mr.
Sandeep Dubey and Dr. Jayant Mishra who guided me all
along till the completion of my report by providing me
resources necessary to develop a good report.

Invented by Dr. Lawrence Farwell in
He is the chief scientist and President of
Human Brain Research Laboratory, USA.
This technology has been proven
successful over 170 cases with a record of
100% accuracy including tests on FBI
agents, tests for a US intelligence agency and
for the US Navy.
WHAT IS BRAIN
Brain Fingerprinting is a scientific,
computer based technique which is used to
determine whether a specific information is
stored in an individual's brain or not.
It measures recognition of familiar stimuli
by measuring electrical brain wave
responses to words, phrases, or pictures
that are presented on a computer screen.
It is based on the theory that throughout any action,
the brain analyze , executes and records that action.
And when the brain recognizes something then there
is some changes in the neurons activity ,due to which
there is changes in brainwave signals .On the basis of
these changes in brain wave signals scientists
determine that a particular information is present in
the subject mind or not.
The brain wave signal which is used in this technique
is well-known brain wave p 300-MERMER.
P300 - MERMER
Memory and Encoding Related Multifaceted
Electrical signal known as P300 is emitted from
an individual’s brain beginning approximately 300
milliseconds after it is confronted with a stimulus
of special significance.
The P300 wave is an event related potential
(ERP) which can be recorded via
electroencephalography (EEG) as a positive
deflection in voltage at a latency of roughly 300
ms in the EEG.
EEG – ELECRTOENCEPHALOGRAPHY
When a stimulus appears, the EEG
breaks into a series of larger peaks and
troughs which constitutes the ERP.
Voltage difference between a pair of
electrodes are measured, filtered,
amplified and recorded for analysis.
First of all the suspect wears a special headset on which many
sensors are fitted to capture the brain wave signals. He is seated
before a comp. system on which stimulies are presented.
3 TYPES OF STIMULIES
• Target : The target stimuli are made relevant and
noteworthy to all subjects.
• Irrelevant : These have no relation to the
situation under investigation.
• Probes : Probes are the stimuli that are relevant
to the situation under investigation.

POLYGRAPH TEST : The existing polygraph test
rely on emotional response. It
measures changes in facial expressions , heartbeat
and sweat on palms. One can pass polygraph test
falsly if he controls these emotional response.
While in Brain Fingerprinting u cant stop ur brain
responsing. It will surely respond to the familiar
stimuli. So this technology is superior to polygraph
The application of Brain Fingerprinting
testing in a criminal case involves four
The first phase is undertaken by a skilled
The second by an interviewer
Only the third one is in the domain of
Fourth by a judge and jury.
What elements do people pay most
attention to ?
What type of media is most effective
How to advertise to people all over
how effective is the product
branding strategy is
In determining who has participated in
terrorist acts, directly or indirectly.
In identifying trained terrorists with the
potential to commit future terrorist acts, even
if they are in a “sleeper” cell and have not
been active for years.
Help to identify people who have knowledge of
terrorist training camps.
Help to determine if an individual is in a
leadership role within a terrorist organization
Identify criminals quickly and scientifically.
Reduce expenditure of money and other
resources in law enforcement.
Reduce evasion of justice.
Access criminal evidence in the brain.
Suspect may lie but the brain never lies.
Record of 100% accuracy.
It does not indicate intent of the crime.
This technology is a little bit
Difficult to distinguish the criminal and
a witness who saw all the criminal
It can detect what information is stored
in the subject’s brain. It can’t detect
how that information got there.
Brain Fingerprinting is a revolutionary
new scientific technology for solving
crimes, identifying perpetrators, and
exonerating innocent suspects, with a
record of 100% accuracy in research
with US government agencies, actual
criminal cases, and other applications.
