Abstract

Brain fingerprinting is based on the theory that throughout a crime and other activities, the brain

plans, records, and executes all of the actions. Such details, all concealed within the brain, can

now be revealed through brain fingerprinting. Brain fingerprinting is a technique that is

advocated as a way to identify a terrorist or other dangerous person or other psychological details

by measuring the "brain-print" of that person when shown a particular body of writing or an

image that was previously familiar i.e. this technique measures how brain waves respond to

specific words or pictures flashed across a screen.

Under the above topic we will discuss about the detailed analysis and working of this upcoming

technology and how will it revolutionize various fields.

Introduction

Brain Fingerprinting was developed and patented in 1995 by Lawrence A.Farwell, Ph.D.,

chairman of the Brain Wave Institute in Fairfield, Iowa, and former Harvard University research

associate.

Brain fingerprinting is based on the theory that throughout a crime, the brain plans, records, and

executes all of the criminal's actions. Brain fingerprinting is a controversial technique that is

advocated as a way to identify a terrorist or other dangerous person by measuring the "brain

print" of that person when shown a particular body of writing or an image that was previously

familiar (such as of a training camp or manual).

In the test, the subject is fitted with a patented headband equipped with sensors and shown a

series of relevant words or pictures on a computer screen. When the brain recognizes something

familiar, the brain elicits a wavelike response known as a MERMER (memory and encoding-

related multifaceted electroencephalographic response) that begins between 300 and 800

milliseconds after the stimulus. The MERMER in turn contains the brain response known as a

P300. The test can be done in as little as 10 minutes.

While conventional lie detectors rely on fluctuations in respiration, perspiration and blood

pressure, "brain fingerprinting" is based on a sub-set of brain waves that register as brief

electrical patterns when a person recognizes familiar stimuli. Imagine, for instance, that a murder

suspect maintains his innocence. While in custody, he is read certain words related to the crime

in question.

Brain fingerprinting is not only limited application field of criminal cases only but has stepped in

various other fields such as advertisements, medicine, psychological and many other.
