Brain fingerprinting is an investigative technique that measures brain wave responses to words, phrases or pictures to determine if an individual recognizes specific information related to an event. It involves wearing a headband with sensors to measure EEG signals while being presented relevant and irrelevant stimuli on a computer screen. Brain fingerprinting has four stages - investigation, subject interview, scientific testing, and adjudication - and has proven 100% accurate in over 120 tests, including for the FBI, US intelligence, and US Navy.

2.  Brain fingerprinting is a technology that is
invented for investigation purpose.
 Brain fingerprinting is a proposed
investigative technique that measures
recognition of familiar stimuli by measurintg
electrical brain wave responses to words,
phrases of pictures that are presented on a
computer screen.

3.  Brain fingerprintin is one of the efficient
investigative technology, developed in
the U.S.A.
 It was invented by Dr. Lawrence A.
Farwall.

4.  Brain fingerprinting is based on finding that
the brain generates a unique brain wave
pattern when a person encounters a familiar
stimulus.
 Use of functional magnetic resonance
imaging in lie detection derives from studies
suggesting that persons asked to lie show
different patterns of brain activity than they
do when truthful.

5.  Brain fingerprinting is designed to determine
whether an individual recognizes specific
information related to an event or activity by
measuring brain wave responses to words,
phrases, or pictures.

6.  The person to be tested wears a special
headband/helmet with electronic sensors that
measure the Electro Encephalo Graphy (EEG)
signals from several locations on the scalp.
 The testee is presented with a series of relevant
and irrelevant words & pictures. The brain
responses to these two types of stimuli allow the
testor to determine if the measured brain
response.

9. There are four stages to Farwell Brain
fingerprinting, which are similar to steps
in fingerprinting and DNA fingerprinting.
1. Investigation.
2. Interview of subject.
3. Scientific testing.
4. Adjudication of guilt or innocence.

10.  Counter Terrorism
 Criminal Justice
 Medical Applications etc.

11.  BFP matches informational evidence from
the crime scene with evidence stored in
the brain rather then physical.
 Fingerprints and DNA are not available in
all occasions. The brain is always there,
planning, executing and recording the
suspect’s actions.

12.  It is fundamentally different from polygraph
test, it doesn’t needs any verbal response.
 It doesn’t needs any emotional sign from
person.

13.  This technology can be applied only in places
where the investigators have sufficient
amount of specific information about an
event or activity.

14.  Brain fingerprinting has proven 100%
accurate in over 120 tests, including tests
on FBI agents, tests for a US intelligence
agency and for the US Navy, and tests on
real life situation including actual crimes.

15.  The technology fulfills an urgent need
for governments, law enforcement
agencies, investigators, crime victims,
and falsely accused innocent suspects
with a record of 100% accuracy.
