It is the technology which explains the crime being done by the person. We can detect whether a person is telling true or false.

4. INTRODUCTION
Brain fingerprinting technology was invented by
Dr. Lawrence A. Farewell

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.

13. APPLICATIONS
• National security
• Medical diagnosis
• Advertising
• Criminal justice system

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.
