3. INTRODUCTION
Brain fingerprinting is a scientific technique to determine
whether or not specific information is stored in an individual's
brain.
Measure the response to the Visual and the Audio stimulus.
It does this by measuring electrical brainwave response to
words ,phrases or pictures that are presented on computer
screen.
4. INVENTION:
Brain fingerprinting was invented by Dr. Lawrence A
in the year 1995. Farwell The chief scientist and
president of Human Brain Research Laboratory, USA.
Is based on the theory that throughout any event, the
brain plans,records and executes all the actions.
5. Equipment and technology:
The brain fingerprinting system comprises:-
1. A personal computer.
2. A data acquisition board.
3. Two monitors.
4. A EEG amplifier.
5. Software for data acquisition Some electrodes.
6. Technique:
When someone commits a crime, his brain records it has
a memory .
Brain Fingerprinting seeks to reveal that memory, by
showing the suspect evidence taken from the crime
scene.
A head band with sensors is placed on the subject.
A series of pictures or words is flashed on the screen.
The computer records the brain waves produced in
response to what the subject sees.
7. P300
The brain responses called a P300/ MERMER are
recorded as a wave form of human neurons which
response to stimulus.
P300 wave is an event related potential (ERP) which can
be recorded via Electroencephalgraphy (EEG).
8. Electroencephalography:
Electroencephalography
(EEG) is the measurement of
electrical activity produced by
the brain as recorded from
electrodes placed on the scalp.
EEG signals (in the range of
mille-volts) are amplified and
digitalized for later processing.
9. Comparison with other technologies:
Brain fingerprinting is fundamentally different from the
polygraph (lie-detector), which measures emotion-based
physiological signals such as heart rate, sweating, and
blood pressure
Also, unlike polygraph testing, it does not attempt to
determine whether or not the subject is lying or telling
the truth.
12. Advantages:
The various advantages are as follows:-
1. The rate of error is extremely low virtually
nonexistent and clear standards governing.
2. Record of 100% accuracy.
3. Identifies the criminal quickly and scientifically.
4. Provides immediate scientific result.
5. Reduced costs and complexities.
6. Support the right to a speedy and fair trail.
13. Disadvantages:
The various disadvantages are as follows:-
1. Not applicable for general screening.
2. It does not indicate intent of the crime.
3. Takes a fair amount of time to set up and conduct
properly .
4. Difficult to distinguish the criminal and a witness
who saw all the criminal activity happen.
14. Conclusions:
Brain Fingerprinting is a revolutionary new scientific
technology for solving The technology fulfills an urgent need
crimes, identifying perpetrators, and for governments, law
enforcement exonerating innocent suspects, with a agencies,
corporations, investigators, record of 100% accuracy in
research crime victims, and falsely accused, with US
government agencies, actual innocent suspects. criminal cases,
and other applications.
