5. BRAIN FINGERPRINTIG
• It is a technique to determine whether an individual recognizes to determine
specific information related to an event or activity by measuring electrical
brain wave responses to words, phrases, or pictures presented on a computer
screen.
6. technique
• The person to be tested wears a special headband with electronic sensors
that measures the electroencephalography from several locations on the
scalp.
• The technique uses the well known fact that an electrical signal known as
p300 is emitted from an individual’s brain. The main thing is that if a person
has committed a crime then only this p300 signal is generated.
7. How the technology works
• When some one commits a crime, his brain records and it has a memory.
• BFP seeks to reveal that memory, by showing the suspect evidence taken
from the crime scene.
• A headband with sensors is placed on the subject.
• A series of pictures or word is flashed on the screen.
8. Working principle
The computer records the brain waves produced in response to what the subject
sees.
The brain responses called a P300 signal are recorded as a waveform.
A suspect is tested by looking at 3 kinds of information represented by different
colored lines:
o RED : Information that suspect expected to know.
o GREEN : Information not known to suspect.
o BLUE : Information of the crime that only perpetrator would.
9. Brain fingerprinting incorporates the following procedure.
A sequence of words or pictures is presented on a video monitor under
computer control.
Three types of stimuli are presented:
I. Targets
II. Irrelevant
III. Probes
10. TARGETS:
It consists of information known to suspects about the crime which will establish a
baseline response and elicit a P300 signal.
IRRELEVANTS:
It consists of information that has nothing to do with the crime so this
IRRELAVANTS do not elicit a P300 signal.
PROBES:
Some of the non-targets stimuli are relevant to the situation under
investigation.
• When the information tested is crime relevant and known only to the suspect and investigators,
then “information present” implies guilty and “information absent” implies innocence.

12. COMPARISON WITH OTHER TECHNOLOGIES:
• Polygraph procedures depends upon autonomic arousal(e.g., palm sweating
and heart rate), while Brain Fingerprinting measures electrical brain activity
via a fitted headband containing special sensors.
• Fingerprints and DNA are available in only 1% of crimes. The brain is
always there, planning, executing, and recording the suspect’s actions.
14. National security
• Identify terrorists and accomplices prior to attacks by determining whether
specific information is embedded in the memory of the subject
15. MEDICAL FIELD
• Alzheimer’s Disease
Detects P300 brainwave.
Symptoms reversible through dietary and medicinal changer.
• Pharmeceutical companies
see effects of new medication.
doctors can monitor treatments and adjust them
16. ADVERTISING
Brain fingerprinting allows advertises to determine what information from
an ad is retained in memory.
• What element do people pay attention to
• What type of media is most effective
• How to advertise to people all over the world
17. Criminal justice
• Used with MERMER technology
• FBI AND CIA endorsed to convict criminals
P300 brainwave is emitted if a memory of presented stimulus exists in the
brain
Difference between perpetrator and the innocent is the memory of the
crime scene embedded in the brain
18. advantages
• Identify criminals quickly and scientifically
• Record of 100% accuracy
• Identify terrorists and members of gangs, criminal and intelligence
organizations
• Reduce expenditure of money and other resources in law enforcement
• Reduce evasion of justice.
19. BENEFITS
• Identify criminal quickly and scientifically.
• Record of 100% accuracy.
• Provide immediate scientific result.
• Reduce cost and complexities.
• Provide straightforward, scientific method of distinguish between criminal
person and the innocent one.
20. CONCLUSION
• Brain fingerprinting is a revolutionary a new technology for solving crime,
with a record of 100% accuracy.
• The technology fulfils an urgent needs for government, law enforcement
agencies, corporations.
