Introduction:

Introduction History. Brain fingerprinting was invented by Dr. B. S. Farwell, The chief scientist and president of Human Brain Research Laboratory, USA. He had tested Brain Fingerprinting technology in over 170 cases. More than 80 of these were in real-life situations, and the rest were laboratory studies. Brain Fingerprinting testing has not made a single error in all of these cases.

Introduction (Contd.):

Introduction (Contd.) Definition "Brain fingerprinting" is a computer-based test that is designed to discover, document, and provide evidence of guilty knowledge regarding crimes , and identify members of dormant terrorist cells. Brain fingerprinting is a technique that measures recognition of familiar stimuli by measuring electrical brain wave responses to words, phrases, or pictures that are presented on a computer screen .

Working principle:

Working principle The entire Brain Fingerprinting system is under computer control, including presentation of the stimuli, recording of electrical brain activity, a mathematical data analysis algorithm that compares the responses to the three types of stimuli and produces a determination of "information present" or "information absent," and a statistical confidence level for this determination.

Working Principle(Contd.):

Working Principle(Contd.) How the technology works. 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.

Working Principle(Contd.):

Working Principle(Contd .) The computer records the brain waves produced in response to what the subject sees. The brain responses called a P300 MERMER are recorded as a wave form. 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:

Scientific Procedure Brain fingerprinting incorporate the following procedure. A sequence of words or pictures is presented on a video monitor under computer control. Each stimulus appears for a fraction of a second. Three types of stimuli are presented: i.) Targets, ii.) Irrelevants, and iii.) probes.

Scientific Procedure (Contd.):

Scientific Procedure (Contd.) The TARGETS stimuli consist of information known to suspect about the crime which will establish a baseline response and elicit a MERMER. The IRRELEVANTS stimuli consist of information that has nothing to do with the crime, which will establish a baseline brain response for information that is not significant to the suspect in context of the crime. These IRRELEVANTS do not elicit a MER- -MER.

Scientific Procedure (Contd.):

Scientific Procedure (Contd.) Some of the non-target 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 guilt and "information absent" implies innocence.

Equipment and Technology.:

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. Some electrodes.

Equipment and Technology (Contd.):

Equipment and Technology (Contd.) Computer Controlled. 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.

Equipment and Technology(Contd.):

Equipment and Technology(Contd.) Computer Controlled (Contd.) 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…..

Benefits:

Benefits Identify criminal quickly and scientifically; Record of 100% accuracy; Confirm innocence, clear the falsely accused, and the falsely convicted; Provide immediate Scientific Result : Information Present or Information Absent, i.e., the crime-relevant information is or is not stored in the brain of the suspect, within a few hours (same day).

Benefits (Contd.):

Benefits (Contd.) Reduce costs and complexities. Provide a straightforward, scientific method of distinguishing between perpetrators and innocent suspects. Access criminal evidence in the brain. Evidence of a crime is virtually always stored in the brain of the perpetrator; fingerprints and DNA, though accurate and highly useful, can only be collected in approximately 1% of all criminal cases. Support the right to a speedy and fair trial.

Conclusion:

Conclusion 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.
