BRAIN FINGERPRINTPRESENTED BY

What is “BRAIN FINGERPRINT”?Brain fingerprinting is a computer based

technology designed to determine hidden information in individual’s brain.

It will analyzed by measuring electrical brain wave responses to words, phrases or pictures presented on a computer screen.

it will be measures by the chief technique of “EEG & P300”.

What is human brain?The human brain is the main organ of the

human central nervous system.The human cerebral cortex is a thick layer of

neural tissue that covers the two cerebral hemispheres that make up most of the brain and act for responses.

The measure of electric activity of brain cortex by means of electrodes is known as electroencephalography(EEG).

What is P300 ?The P300 (P3) wave is an event related

potential (ERP) component elicited in the process of decision making.

It is usually elicited using the “oddball paradigm”.

It consists of mainly two subcomponents “p3a &p3b”.

The P3a has been associated with brain activity related to the engagement of attention.The P3b has been a prominent tool used to

study cognitive processes, especially psychology research

on information processing.

Brain fingerprint technique?Firstly the p300 was been placed on the

forehead for to notify the response of brain.Each response will denotes a specific colourRED: information is known by the suspect.GREEN: information is not known by suspect.BLUE: Information of the crime that only

perpetrator would know.

Brain fingerprint technique?As we observed the monitoringRed is not resemble with theBlue matter so info not obtained• Red response is P300 so to Initialise the reference information• When second response, blue interact with

green one so that the initial response is recorded

Brain fingerprint technique?Number of trails has been recorded are min

60These trails gives an extreme response about

the info present on the brain.

How it works?The Main Modules Of Testing Brain Fingerprint is:

• Recording of electrical brain activity

• Mathematical data analysis algorithm that compares the responses of the 3 Functions

• Presentation of the Response

• Determination of information present or information absent

How it works?Firstly the info related to crime or incident is

preloaded into p300.These sensor(p300) assumption is taken along with brain wave , eye response and along with sensor reading of test person.

How it works?The wave responses are generated as shown

in figureThe first response shown that the person is

not related to crime.The second response shows the person is related to crime.

How it works?

As We observe the first response, the blue ray is not been linked with red (p300) response, so the crime was not commited by the person

The above response spences that the red mermer response is linked with the blue wave so that the crime was committed by the person

How it works?The total trails was taken into consideration

and make a step boot up analysis

Brain Fingerprint (vs) Lie detector

For analysing the lie detector , it responses depends on heartbeat, pulse etc.But as in brain fingerprinting, only the brain responses is analysed

Present using fields!!Brain fingerprint is mainly used in the federal

bureau of investigation(FBI).Central bureau of investigation(CBI) For

Suspect Analysis.This technique mainly used to Suspect the person if clues Resolving is negligible.

LimitationsBrain fingerprint is initialise what info stores in the brain, it

doesn’t initialise how the info was stored in brain. It resembles the brain response, there is no right to judge

the criminal , it only finalise by the honorable justice.
