3. INTRODUCTION
 Brain Fingerprinting technique used to determine scientifically
what information is, or is not stored in a brain.
 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.

4. THE INVENTION
 Brain fingerprinting was invented by Dr. Lawrence Farwell.
 Brain Fingerprinting technology is based on an electrical signal
known as P300-MERMER.
 Farwell's brain fingerprinting originally used the well-
known P300-MERMER brain response to detect the brain's
recognition of the known information.
 First used in USA in 2001, India is the second country to use
brain fingerprinting in courts.

6. P300- MERMER
 Farwell used the P300-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..
 When the brain recognizes something, then there is
increase in neurons activity, so elicit some changes in brain
wave signals .

8. TYPES OF STIMULI
 There are 3 types of stimuli are used.
Target.
Irrelevant stimuli.
Probes.

9. HOW IT WORKS?
 The suspect is tested by looking at three kinds of
information represented by different colored lines-
 --Red: Information the suspect is expected to know.
 --Blue: Information of crime only the perpetrator would
know.
 --Green: Information not known to the suspect.

11. STAGES OF BRAIN FINGERPRINTING
Crime Scene Evidence Collection.
Brain Evidence collection.
Computer Evidence Analysis.
Scientific Result.

12. ADVANTAGES
 100% accuracy.
 Identify criminals, terrorists quickly.
 Reduce evasion of justice.
 Human rights oriented.
12

13. DISADVANTAGES
It does not detect how information got into brain.
It does not describe the intent.
Cannot be applied if investigation is inaccurate.
13

14. APPLICATIONS
Counter terrorism.
Criminal justice.
Medical field.
Advertising.

15. CONCLUSION
 Brain Fingerprinting is a revolutionary scientific technique
with 100% accuracy.
 Promises to void future tampered evidence.
 Also applicable in medical field.
