Brain fingerprinting uses MERMER signals (electrical brainwave responses) to determine if a person has information stored in their brain. Electrodes detect brainwaves in response to visual or audio stimuli. It has been used to identify criminals and can determine guilt or innocence with 100% accuracy, helping to reduce legal costs and avoid injustices. While promising, more research is needed due to small sample sizes in previous studies.

3. INTRODUCTION
Brain Fingerprinting technique used to
determine scientifically what information is,
or is not stored in a particular brain.
Not a measure of guilt or innocence.
Measures the response to visual or audio
stimulus.
Invented by Dr Lawrence A. Farwell.

4. BASED ON
Brain Fingerprinting method is based
on an electric signal which is known as
MERMER .

5. What is MERMER?
A MERMER is an electrical signal which is a
part of the brainwave observed in response
to familiar information.
When the brain recognizes something, then
there is increase in neurons activity, so elicit
some changes in brain wave signals .

6. Instrumental Requirements
 Personal computer
 A data acquisition board
 A graphics card for driving two monitors from
one PC
 A four-channel EEG amplifier system
 Software developed by the Brain Fingerprinting
lab.6

7. How it works ?
Brain Fingerprinting method uses a signal which
is known as MERMER i.e. Memory and Encoding
Related Multifaceted Electroencephalographic Response.
A sequence of words, phrases, or pictures is
presented on a video monitor to the subject,
wearing a special headband designed for detecting
the brain wave responses.7

9. Electroencephalography
 Electroencephalography (EEG) is the measurement
of electrical activity produced by the brain as
recorded from electrodes placed on the scalp.
 Scalp EEG is collected from tens to hundreds of
electrodes positioned on different locations at the
surface of the head.
 EEG signals(in the range of milli volts) are
amplified and digitalized for later processing.

12. Advantages
 Identify criminals quickly and
scientifically
 Record of 100% accuracy
 Reduce expenditure of money and other
resources in law enforcement
 Reduce evasion of justice.

13. Comparisons with other
technologies
 Fingerprints and DNA are available in only 1% of crimes.
The brain and the evidence recorded in it are always
there.
 No questions are asked and no answers are given during
Farwell Brain Fingerprinting.
 Brain Fingerprinting technology depends only on brain
information processing, it does not depend on the
emotional response of the subject.

14. Conclusion
 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.
