3.  Brain fingerprinting is a controversial, unproven and
questionable technique invented by Lawrence Farwell which he
uses ”Electro Encephalo Graphy” (EEG) to determine whether
specific information is stored in a subject's brain.
 The technique consists of the measuring and recording a
person's electrical brainwaves and their brain response.
 Farwell's brain fingerprinting originally used the well known P300
brain response to detect the brain's recognition of the known
information
INTRODUCTION

4. Brain Fingerprinting technology is based on an electrical signal known
as MERMER.
Farwell discovered the P300-MERMER .
MERMER - "Memory and Encoding Related Multifaceted
Electroencephalographic Response“ .
A MERMER is an electrical signal which is part of the brainwave
observed in response to familiar information.
MERMER

5.  Brain Fingerprinting technique used to determine scientifically
what information is, or is not stored in a particular brain.
 When the brain recognizes something, then there is increase in
neurons activity, so elicit some changes in brain wave signals .
 This technique measures the response to the Visual and the
Audio stimulus.
 Stimulus is a thing or event that evokes a specific functional
reaction in an organ or tissue.
 It does this by measuring electrical brainwave responses to
words, phrases, or pictures that are presented on a computer
screen.
OPERATION

OPERATING MECHANISM

7. A suspect is tested by looking at three kinds of information represented
by different colored lines .
 RED : Information the suspect is expected to know. It arises due to
target type stimulus.
 GREEN : Information not to suspect. The irrelevant stimuli is
responsible for this type of brain waves.
 BLUE : Information of the crime that only perpetrator would know.
This occurs due to probes.
DIFFERENT TYPES OF BRAIN WAVES

9. EXAMPLE OF A SUBJECT
 The Following figure shows the RED and BLUE lines are closely
correlated.
 This indicates the suspect or the criminal has the knowledge of the
CRIME.

10.  Crime Scene Evidence Collection : Collecting the data
physically at the crime scene area .
 Brain Evidence collection : Collecting the data from the brain
using certain tools.
 Computer Evidence Analysis : Analysing the data/evidence
using computer device for better comparison.
 Scientific Result : Showing the Result after the analysis
,showing whether the Data is correct or not .
STAGES OF BRAIN FINGER PRINTING

11.  Brain fingerprinting is a computer-based test that is designed to
discover, document.
 It has also been used to evaluate brain functioning as a means of early
detection of Alzheimer's and other cognitively degenerative diseases,
and to evaluate the effectiveness of advertising by measuring brain
responses.
 Basically Brain fingerprinting is not lie detection. It is different from
polygraph(lie-detector), which measures emotion-based physiological
signals such as heart rate, sweating and blood pressure .
FEATHURES

12.  To identify individuals with a specific training or expertise such
as members of dormant terrorist cells or bomb makers. The
National Security is one of the application.
 To evaluate the effectiveness of advertising by measuring brain
responses. to evaluate brain functioning It is applied in the
Medical field.
 It works on brain functioning by detecting the brain waves. It can
help solve crimes.
APPLICATIONS

13.  Brain fingerprinting detects information-processing brain responses
that reveal what information is stored in the subject's brain. It does
not detect how that information got there.
 Brain fingerprinting does not detect lies. It simply detects
information. No questions are asked or answered during a brain
fingerprinting test.
LIMTATIONS

14.  It would be inappropriate to generalize the results of the present
research because of the small sample of subjects.
 But the 100% accuracy and high confidence level of the results,
however, provide further support for results from previous
research using brain MERMER testing.
 If this project is successful .Then it can bring a revolution in
scientific field .
