What is Brain Fingerprinting?Brain fingerprinting is a computer basedtechnique for determining a certain informationstored in the brain by measuring brain waves.Brain fingerprinting is a Technique used toidentify a terrorist or other dangerous person bymeasuring the “brain print” of that particularperson..
Quick Overview • Invented By Dr Lawrence A. Farwell. • It’s a patented technique of proven accuracy in US government tests. • Ruled Admissible in one US Court as scientific evidence. • It has a record of 100% Accuracy.
Types of Stimuli UsedProbes o Life-experience related o Relevant to the investigated event -recognizable and noteworthy only for the subjects who had participated in the event (MERMER) o Indistinguishable from the Irrelevants for a subject who is not knowledgeable about the situation under investigationTargets o Push a button to indicate known image o Since the relatively rare Targets are singled out in the task being performed, the Targets are noteworthy for the subject, and each Target stimulus elicits a MERMER Irrelevant Stimuli o information relevant to the crime that the suspect claims to have no knowledge of
Instrumental requirements•Personal Computer•A Data acquisition board•A Graphics card for driving two monitorsfrom one PC• A four-channel EEG amplifier system•Software developed by the BrainFingerprinting Laboratories for dataacquisition and analysis.
How it works ?The person to be tested wears a special headbandwith electronic sensors that measure the EEG fromseveral locations on the scalp. The subject viewsstimuli consisting of words, phrases, or picturespresented on a computer screen.
Electroencephalography:Electroencephalography (EEG) is themeasurement of electrical activity produced bythe brain as recorded from electrodes placed onthe scalp.Scalp EEG is collected from tens to hundredsof electrodes positioned on different locations atthe surface of the head.EEG signals(in the range of milli volts) areamplified and digitalized for later processing.
Brain Fingerprinting in India Brain Fingerprinting in India The Gujarat government hasconstituted an eight-member ethics committee headed by ahigh court judge, to monitor and establish newly acquiredtechniques of crime detection. The technique being perusedby this committee at this juncture is the use of BRAINFINGERPRINTING on the accused an suspects in India.Anand Yagnik, an advocate at the Gujarat High Court anda member of this committee said : The ethicalconsiderations to be kept in mind while conducting newtechniques of crime detection like the brain fingerprinting.

Comparisons with othertechnologies • Fingerprints and DNA are available in only 1% of crimes. The brain and the evidence recorded in it are always there. • No questions are asked and no answers are given during Farwell Brain Fingerprinting. • Brain Fingerprinting technology depends only on brain information processing, it does not depend on the emotional response of the subject.
Other Applications There are several other areas in which Brain fingerprinting can be used to make life easier and can aid mankind in many ways. Key fields where brain fingerprinting can be used are: • Counter terrorism • Criminal justice • Medical • Advertising
Conclusion • It would be inappropriate to generalize the results of the present research because of the small sample of subjects. • But the 100% accuracy and high confidence level of the results, however, provide further support for results from previous research using brain MERMER testing.
