We all are familiar with fingerprinting. But have you heard about brain fingerprinting?. This is a technology that is used to identify terrorist and other dangerous person by measuring the brainprint of that person. This is done using a series of brainwave components based on P300 complex. This technique is more effective than a lie detector. This was invented by Dr.Lawrence Farwell.
Memory and Encoding-Related Multifaceted in turn Response
This technique can be used to identify the person who has done the crime. In this test the person is fitted with a patented headband equipped with sensors and shown a series of relevant words or images on a display screen. Once the brain identifies something familiar, the brain elicits a wavy response called a MERMER (memory and encoding-related multifaceted in turn response). The MERMER successively contains the brain response called a P300. The test may be done in as very little as 10 minutes.
As a counter-terrorist measure at airports or different places, the technique, if mandated, might be challenged as a possible violation of privacy. Critics also question whether brain fingerprinting might be administered with efficiency. And while not a substantial range of false readings. They also ask however it might be used to screen for terrorists who had not been exposed to the words or photos being shown.
Brain fingerprinting is designed to determine whether an individual recognizes specific information related to an event or activity by measuring electrical brain wave responses to words, phrases or pictures on a computer screen. The technique can be applied only in situations where investigators have a sufficient amount of specific information about an event that would be known only to the perpetrator and investigator.
Brain fingerprinting testing includes the following steps. A sequence of words, pictures or sounds is presented under computer control for a fraction of second. Three types of stimuli are presented:
The target consist of the information known to the suspect; which will create a baseline brain response (MERMER) for information known to be significant to this suspect in the context of the activity. Moreover the subject is given a list of the target stimuli and instructed to press a particular button; in response to target and another button in response to all other stimuli.
Most of the non-target stimuli are irrelevant; that are having no relation to the situation under investigation. Also some of the non-target stimuli are relevant to the situation under investigation. These relevant stimuli are known as probes; information relevant to the crime.
The full Brain fingerprinting system is under computer control, including presentation of the stimuli; recording of electrical brain activity, a mathematical information analysis algorithm that compares the responses to the three forms of stimuli and produces a determination of “information present” or “information absent,” and a statistical confidence level for this determination.0
