NIRMAL YADAV 4

INTRODUCTION Invented by Dr. Lawrence Farwell in 1995.

He is the chief scientist and President of Human Brain Research Laboratory, USA.

This technology has been proven successful over 170 cases with a record of 100% accuracy including tests on FBI agents, tests for a US intelligence agency and for the US Navy.

WHAT IS BRAIN FINGERPRINTING ? Brain Fingerprinting is a scientific,

computer based technique which is used to determine whether a specific information is stored in an individual's brain or not.

It measures recognition of familiar stimuli

by measuring electrical brain wave responses to words, phrases, or pictures that are presented on a computer screen.

NIRMAL YADAV 7

BASIC PRINCIPLE

It is based on the theory that throughout any action, the brain analyze , executes and records that action.

And when the brain recognizes something then there is some changes in the neurons activity ,due to which there is changes in brainwave signals .On the basis of these changes in brain wave signals scientists determine that a particular information is present in the subject mind or not.

The brain wave signal which is used in this technique is well-known brain wave p 300-MERMER.

TECHNIQUE USED

P300 - MERMER

Memory and Encoding Related Multifaceted Electroencephalographic Response

Electrical signal known as P300 is emitted from an individual’s brain beginning approximately 300 milliseconds after it is confronted with a stimulus of special significance.

The P300 wave is an event related potential (ERP) which can be recorded via electroencephalography (EEG) as a positive deflection in voltage at a latency of roughly 300 ms in the EEG.

EEG MEASUREMENT

EEG – ELECRTOENCEPHALOGRAPHY When a stimulus appears, the EEG breaks into a series of larger peaks and troughs which constitutes the ERP.

Voltage difference between a pair of electrodes are measured, filtered, amplified and recorded for analysis.

First of all the suspect wears a special headset on which manysensors are fitted to capture the brain wave signals. He is seatedbefore a comp. system on which stimulies are presented.

3 TYPES OF STIMULIES

• Target : The target stimuli are made relevant and noteworthy to all subjects.

• Irrelevant : These have no relation to the situation under investigation.

• Probes : Probes are the stimuli that are relevant to the situation under investigation.

COMPARISONS WITH OTHER TECHNOLOGY

POLYGRAPH TEST : The existing polygraph test rely on emotional response. It measures changes in facial expressions , heartbeat and sweat on palms. One can pass polygraph test falsly if he controls these emotional response.

While in Brain Fingerprinting u cant stop ur brain responsing. It will surely respond to the familiar stimuli. So this technology is superior to polygraph test.

CRIMINAL PROCEEDINGS

The application of Brain Fingerprinting testing in a criminal case involves four phases: investigation, interview, scientific testing, and adjudication.

The first phase is undertaken by a skilled investigator

The second by an interviewer Only the third one is in the domain of science.Fourth by a judge and jury.

APPLICATIONS

NIRMAL YADAV 16

ADVERTISING

What elements do people pay most attention to ?

What type of media is most effectiveHow to advertise to people all over the world

how effective is the product branding strategy is

NIRMAL YADAV 17

Counter TerrorismIn determining who has participated in

terrorist acts, directly or indirectly.

In identifying trained terrorists with the potential to commit future terrorist acts, even if they are in a “sleeper” cell and have not been active for years.

Help to identify people who have knowledge of terrorist training camps.

Help to determine if an individual is in a leadership role within a terrorist organization

NIRMAL YADAV 18

ADVANTAGES

Identify criminals quickly and scientifically.

Reduce expenditure of money and other resources in law enforcement.

Reduce evasion of justice.

Access criminal evidence in the brain.

Suspect may lie but the brain never lies.

Record of 100% accuracy.

NIRMAL YADAV 19

LIMITATIONS

It does not indicate intent of the crime.

This technology is a little bit controversial.

Difficult to distinguish the criminal and a witness who saw all the criminal activity happen.

It can detect what information is stored in the subject’s brain. It can’t detect how that information got there.

NIRMAL YADAV 20

CONCLUSION Brain Fingerprinting is a revolutionary

new scientific technology for solving crimes, identifying perpetrators, and exonerating innocent suspects, with a record of 100% accuracy in research with US government agencies, actual criminal cases, and other applications.
