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.
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
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
3. 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
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.
