INTRODUCTION
Brain fingerprinting is a controversial
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.
Brain fingerprinting is a technology that is invented for use by investigation purpose.

DEVELOPMENT
Brain fingerprinting is one of the efficient
investigative technology, developed in the
United
States of America.
It was invented by Dr. Lawrence A. Farwall.

WHAT IS BRAIN FINGERPRINTING ? . .
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.

BRAIN FINGERPRINTING
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.

TECHNIQUE
The person to be tested wears a special headband with electronic sensors that measure the Electro Encephalo Graphic (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.

PHASES OF BRAIN FINGERPRINTING
There are four stages to Farwell Brain fingerprinting, which are similar to steps in fingerprinting and DNA fingerprinting.
I. Brain fingerprinting Crime Scene Evidence Collection.
II. Brain fingerprinting Brain Evidence Collection.
III. Brain fingerprinting Computer Evidence Analysis, and
IV. Brain fingerprinting Scientific Result.

APPLICATIONS
- Counter Terrorism- Criminal Justice

COMPARISON WITH OTHER TECHNOLOGIES
Brain fingerprinting 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.

ADVANTAGE
It is fundamentally different from
polygraph test, it doesn’t needs any verbal
response.

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

ADMISSIBILITY IN COURT
The following established features of Brain fingerprinting will be relevant when the question of admissibility is tested in court.
Brain fingerprinting has been thoroughly and scientifically tested.The rate of error is extremely low.The theory and practice of brain fingerprinting have gained general acceptance in the relevant scientific community.

ACCURACY
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.

CONCLUSION
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.
