2. WHAT IS BRAIN FINGERPRINT ?
 Brain fingerprinting is a computer based technology designed to determine hidden
information in individual’s brain.
 It will analyzed by measuring electrical brain wave responses to words, phrases or
pictures presented on a computer screen.
 It will be measures by the chief technique of “EEG & P300”.

3. INVENTED BY :
• Dr. Larry Farwell, Ph. D. is the inventor of Brain Fingerprinting, a scientific method to
discover the truth, identify criminals and terrorists, and clear the innocent with extremely high
accuracy by measuring brainwaves. He invented the first brain-computer interface.

4. WHAT IS P300 AND EEG ?
• An electroencephalogram (EEG) is a test
that detects electrical activity in your brain
using small, metal discs (electrodes)
attached to your scalp. Your brain cells
communicate via electrical impulses and
are active all the time, even when you're
asleep. This activity shows up as wavy lines
on an EEG recording

5. WORKING OF BRAIN FINGERPRINTING:
• Brain Fingerprinting detects information stored in the
• individual brain. Sensors on a headband, list the subject's EEG, or brain signal reaction to the processor images. The EEG is feed all the
way through an amp and into a processor that uses proprietary software to display and interpret the brain effect. A specific, electrical
brain sign reaction, known as a P300, is emitted by the intelligence within a division of a succeeding when a personality recognize and
process an inward incentive that is important or notable. When an immaterial spur is seen, it is seen as being not important and not
notable and a P300 is not emitted. In his research on the
• P300 response, Dr. Farwell exposed that the P300 was one portion of a bigger theory reaction that he named a MERMER (memory and
encoding related multifaceted electroencephalo-graphic response).MERMER comprises a P300 reaction, happening 300 to 800ms after
the spur, and supplementary patterns happening more than 800ms behind the spur, given that even supplementary exact domino effect
using Many-sided electroencephalographic reaction study (MERS), shows that a specific many-sided electroencephalographic response
(MER), known as a memory and programming related many-sided electroencephalographic reaction (MERMER), is elicited when a person
recognizes and processes a spur that is predominantly essential to him/her.
• The MERMER includes: the P300, an electrically positive component maximal at the parietal scalp location, longer latency, electrically
pessimistic subcomponent famous at the frontal scalp site, and Physic changes in the rate of recurrence and arrangement of the gesture.

6. USING BRAIN WAVES TO DETECT GUILTY WORKING:
• A Suspect is tested by looking at three kinds of information represented by Different colored lines:
• Red: information the suspect is expected to know.
• Green: information not known to suspect.
• Blue: information that only perpetrator would know.
• Information not present:Because the blue and green lines closely correlate, suspect does not have critical knowledge of the crime.
• Information Present:Because the blue and red lines closely correlate and suspect has critical knowledge of the crime.
