2. INTRODUCTION
Brain fingerprinting was developed and patented in 1995 by dr.
Lawrence a. farwell .
Is based on the theory that throughout any action the brain
plants , record , and executes all of the actions
“Brain fingerprinting” is a controversial forensic science
technique that determines whether specific information is
stored in a subjects brain by measuring electrical brainwave
response to words ,phrases,or picture that are presented on a
computer screen
3. What is brainfingerprinting
Brain fingerprinting is a computer based
technology designed to determine hidden
information in individuals brain by
measuring electrical brain wave responses
to words , phrases or pictures presented on
a computer screen
Brain fingerprinting are measured by an
EEG event-related potential,a P300-
MERMER
4. P300:
Specific,measurable brain response emitted by the
Brain of a subject who as the relevant information
Stored in his brain it is based on oddball paradigm
MERMER:
Memory and encoding related multifaceted
Electroencephalographic response it is a patented
device And comes along with a head gear

6. TYPES OF STIMULI USED
PROBES
-life-experience related
-relevant to the investigated event-recognizable and noteworthy only for
the subject who had participated in the event(MERMER)
TARGETS
-push a button to indicate known image
-contains relevant information
-creates a baseline
IRRELEVENT STIMULI
-information relevant to the crime that the suspect claims to have no knowledge of
7. How brain waves are used to decect guilt
INFORMATION OF THE CRIME THAT ONLY PERPETRATOR
WOULD KNOW.THIS OCCURS DUE TO PROBES
INFORMATION NOT TO SUSPECT.THE IRRELEVENT STIMULI IS
RESPONSIBLE FOR THIS TYPE OF BRAIN WAVES
INFORMATION THE SUSPECT IS EXPECTED TO KNOW IT ARISES
DUE TO TARGET TYPE STIMULUS
A SUSPECT IS TESTED BY LOOKING AT THREE KINDS OF
INFORMATION REPRESENTED BY DIFFERENT COLORED
LINES

9. PHASES OF BRAIN FINGERPRINTING
There are four stages to brain fingerprinting
1.Crime scene evidence collection:gathering evideance
from crime scinse
2.Brain evidences collections: a specialist checks whether
the crime scene evidence matches evidence stored in brain
3.Computer evidences analysis: computerized analysis is
done on the brain evidences And statistical methods are
applied to move to the next phase
4.Scientific result: finding whether the person is guilty or
not guilty
10. CURRENT USES AND APPLICATIONS
THIS IS VARIOUS APPLICATIONS ARE FALLOW:-
TEST FOR SEVERAL FORMS OF EMPLOYMENT,ESPECIALLY IN DEALING WITH
SENSITIVE MILITARY AND FOREIGN INTELLIGENCE SCREENING
INDIVIDUALS WHO WERE “INFORMATION PRESENT” AND “INFORMATION
OBSENT”
A GROUP OF 17 FBI AGENTS AND 4 NON-AGENTS WERE EXPOSED TO
STIMULI.
TO DETECT SYMPTOMS OF ALZHEIMER’S DISEASE,MENTAL DEPRESSION AND
OTHER FORMS OF DEMENTIA INCLUDING NEUROLOGICAL DISORDERS
CRIMINAL CASES,SECURITY TESTING,COUNTER-TERRORISM
ADVERTISEMENTS(RESEARCHES ARE BEING CARRIED ON)
11. MEDICAL APPLICATIONS
RESEAECH HAS NOW DEMONSTRATED THAT ANALYSIS OF THE P300
BRAINWAVE CAN SHOW DEMENTIA ONSET AND PROGRESSION.MERMER
TECHONOLOGY ,DEVELOPHED AND PATENTED BY BRAIN FINGERPRINTING
LABORATORIES,INCLUDES THE P300 BRAINWAVE AND EXTENDS
IT,PROVIDING A MORE SENSITIVE MEASURE THAN THE P300 ALONE
ADVERTISING APPLICATIONS
WHAT SPECIFIC INFORMATION DO PEOPLE RETAIN FROM ADVERTISING
WHAT SPECIFIC ELEMENTS IN AN AD CAMPAIGN HAVE THE MOST IMPACT
WHICH TYPE OF MEDIA IS MOST EFFECTIVE?
WHAT COMMERICIAL IS THE MOST EFFECTIVE FOR A SINGLE PRODUCT
12. LIMITATIONS OF BRAIN FINGERPRINTING
IT DOES NOT DETECT HOW THAT INFORMATION GOT THERE
BRAINFINGERPRINTING DETECTS ONLY INFORMATIONS,AND NOT INTENT
WHERE THE SUSPECT KNOWS EVERYTHING THAT THE INVESTIGATIONS CAN ASK.
AUTHORITIES HAVE NO INFORMATION ABOUT WHAT CRIME MAY HAVE TAKEN
PLACE.
GENERAL PRE-EMPLOYMENT OR EMPLOYEE SCREENING WHEREIN ANY NUMBER OF
UNDRSIRABLE ACTIVITIES OR INTENTIIONS MAY BE RELEVANT
BRAIN FINGERPRINTING DOES NOT DETECT LIES.IT SIMPLY DETECTS
INFORMATION.
THE LIMITATIONS ON HUMAN MEMORY AND THE FACTORS AFFECTING IT
