What is Brain Fingerprinting?
Brain Fingerprinting is a scientific technique to determine whether or not specific information is stored in an individual's brain.
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.
How it works ?
On seeing a previously known information, a specific measurable brain response known as a P300 or MERMER i.e. Memory and Encoding Related Multifaceted Electroencephalographic Response, is elicited by the brain of a subject.

Target : The target stimuli are made relevant and noteworthy to all subjects.
Irrelevant : These have no relation to the situation under investigation.
The targets provide a template for a response that will be generated when a subject recognizes a stimuli familiar to the situation under investigation.
The irrelevant provide a template, for a response that will be generated when a subject don’t recognizes a stimuli familiar to the situation under investigation.
For each probe stimulus, there are approximately four irrelevant stimuli and one target stimuli.
The targets, since they are recognized and require a particular response, are noteworthy for all subjects.
The irrelevant are not noteworthy for any subjects.
The probes are noteworthy only to the subjects who have the knowledge specific to the situation under investigation.
A subject lacking specific information relevant to the situation under investigation recognizes only two types of stimuli: Targets & Irrelevents.
A subject with specific information relevant to the situation under investigation, however, recognizes all three types of stimuli: Targets Irrelevents & probes.
The main function of our experimental design is, to create a two-stimulus series for an individual without the specific information under investigation, and a three-stimulus series (with the same stimuli) for an individual who possesses knowledge of the specific information under investigation.
The determination of information present in one’s brain consists of comparing the probe responses to the target responses, which contain a P300/MERMER, as both are noteworthy to the subject.
This pattern occurs within less than a second after the stimulus presentation, and can be readily detected using EEG amplifiers and a computerized signal-detection algorithm.
In order for the test to be an effective indicator of knowledge or lack thereof, stimuli must be structured such that only a knowledgeable person would recognize the probe stimuli.
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 absent" or "information present.“
Results
Results have shown this technique to be capable of producing an "information absent" or "information present" determination, with a strong statistical confidence, in approximately 90% of the cases studied. All of the determinations were accurate. In the other 10% of cases the mathematical algorithm determined that there was insufficient information to make determination
Instrumental Requirements
personal computer
a data acquisition board
a graphics card for driving two monitors from one PC
a four-channel EEG amplifier system
software developed by the Brain Fingerprinting Laboratories for data acquisition and analysis.
