Introduction:-
Brain fingerprinting was invented by Dr. Lawrence A. Farewell, the chief scientist and president of Human Brain Research Laboratory, USA
He has tested Brain Fingerprinting Technology in over 170 cases. More then 80 of these were in real-life situations, and the rest were laboratory studies. Brain Fingerprinting testing has not made a single errors in all these cases.
What is Brain Fingerprinting?
Scientific technique to determine whether or not specific information is stored in an individual’s brain or it is a technique to determine whether an individual recognizes specific information related to an event or activity by measuring electrical brain wave responses to words, phrases, or pictures presented on a computer screen.
How the technology works?
when someone commits a crime, his brain records and it has a memory.
Brain Fingerprinting seeks to reveal that memory, by showing the suspect evidence taken from the crime scene.
A headband with sensors is placed on the subject.
A series of pictures or word is flashed on the screen.
Working Principle(contd.)
The computer records the brain waves produced in response to what the subject sees.
The brain responses called a P300 signal are recorded as a waveform.
A suspect is tested by looking at 3 kinds of information represented by different colored lines:
. Red: Information that suspect expected to know.
Green: Information not known to suspect.
Blue: Information of the crime that only perpetrator would.
WORKING PRINCIPLE(CONT.)
brain fingerprinting incorporate the following procedure.
A sequence of words or pictures is presented on a video monitor under computer control.
Three types of stimuli are presented:
Targets
Irrelevant
Probes
WORKING PRINCIPLE(CONT.)
The TARGETS stimuli consists of information known to suspects about the crime which will establish a baseline response and elicit a P300 signal.
The IRRELEVANTS stimuli consists of information that has nothing to do with the crime so this IRRELEVANTS do not elicit a P300 signal.
WORKING PRINCIPLE(CONT.)
Some of the non-targets stimuli are relevant to the situation under investigation. These relevant stimuli are referred to as PROBES.
When the information tested is crime relevant and known only to the suspect and investigators, then “information present” implies guilty and “information absent” implies innocence.
Comparison with other technologies:-
polygraph procedures depends upon autonomic arousal (e.g., palm sweating and heart rate), while Brain Fingerprinting measures electrical brain activity via a fitted headband containing special sensors.
Fingerprints and DNA are available in only 1% of crimes. The brain is always there, planning, executing, and recording the suspect's actions.
Benefits:-
Identify criminal quickly and scientifically.
Record of 100% accuracy.
Provide immediate scientific result.
Reduce cost and complexities.
Provide straightforward, scientific method of distinguish between criminal person and the innocent one.
Conclusion:-
Brain Fingerprinting is a revolutionary a new technology for solving crime, with a record of 100% accuracy.
The technology fulfills an urgent needs for government, law enforcement agencies, corporations.
