BRAIN FINGER PRINTING
Introduction
 Brain fingerprinting is a scientific technique to determine whether or not specific information is stored in an individual's brain.
 Brain fingerprinting was invented by Dr. Lawrence A. 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.
Definition
 "Brain fingerprinting" is a computer-based test that is designed to discover, document, and provide
evidence of guilty knowledge regarding crimes.
 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 .
Equipment and technology
The brain fingerprinting system comprises
 A personal computer.
 A data acquisition board.
 Two monitors.
 A EEG amplifier.
 Software for data acquisition
 Some electrodes.
Computer controled:
 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 subjecton one monitor,and the investigator views another monitor.
Working principle
 Entire system under computer control includes
 Presentation of the stimuli.
 Recording of electrical brain activity.
 Determination of "information present" or "information absent," .
 Mathematical data analysis algorithm that compares the responses
statistical confidence level for the determination.
How the technology work
 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 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.
Crime Control Information
 Information is absent
 Information is present
SCIENTIFIC PROCEDURE
 Stimulus appears for a fraction of a second when they are presented on a video monitor under computer control.
 Three types of stimuli are presented:
1) Targets,
2 ) Irrelevants, and
3 ) probes.
 TARGETS stimuli Info known to suspect about the crime
Elicits a MERMER.
 IRRELEVANTS stimuli Info not related to the crime
Do not elicit a MERMER.
 PROBES stimuli Info relevant to the situation under investigation that only the perpetrators knows Elicits a MERMER.
Application
 National Security.
 To test job applicants on the falsification of an application.
 Medical Field.
 Helps in Identifying false-witnesses.
Benefit
 Identify criminal quickly and scientifically,record of 100% accuracy.
 Provide immediate Scientific Result : Information Present or Information Absent.
 Reduce costs and complexities.
 Support the right to a speedy and fair trial.
Disadvantages
 Not applicable for general screening.
 It does not indicate intent of the crime.
 Takes a fair amount of time to set up and conduct properly .
 Difficult to distinguish the criminal and a witness who saw all the criminal activity happen.
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.
