WHAT IS BRAIN FINGERPRINTING?
The fundamental difference between the perpetrator of a crime and an innocent person is that the perpetrator, having committed the crime, has the details of the crime stored in his memory, and the innocent suspect does not.
This is what Brain Fingerprinting testing detects scientifically, the presence or absence of specific information.
How the technology works?
Working Principle:
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.
The brain responses called are recorded as a wave form a P300 MERMER
By analyzing MERMER (Memory and Encoding Related Multifaceted Electroencephalographic Response) the pattern of waves, Farwell can determine if the subject is recognizing what he is seeing.
Scientific Procedure
Equipment and Technology
The brain fingerprinting system comprises
A personal computer (Pentium iv,1 GHz, IBM PC).
A data acquisition board .
Two monitors.
A EEG amplifier.
Software for data acquisition.
Electrodes
The electrodes to used to measure electrical brain activity.
The software presents the stimuli, collects the EEG data, and analyzes the data.
Brain electrical activity amplified and stored on a memory device.
During the data collection ,the stimuli are
displayed to the subject on one monitor, and the investigator views another monitor.
Investigator gets the summary of the textual information and the wave form as follows…..
Brain Fingerprinting is a revolutionary new technology for solving crimes, with a record of 100% accuracy.
The technology fulfills an urgent need for governments, law enforcement agencies, corporations, and individuals in a trillion-dollar worldwide market. The technology is fully developed and available for application in the field.
