Brain Fingerprinting

The entire Brain Fingerprinting system is under computer control, including presentation of the stimuli, recording of electrical brain activity and a mathematical data analysis algorithm that compares the responses to the three types of stimuli and produces a determination of "information present" or "information absent".

HISTORY
1. Brain fingerprinting was invented and patented by Dr. B. S. Farwell, the chief scientist and president of Human Brain Research Laboratory, USA in 1995.
—2. He had tested Brain Fingerprinting technology in over 170 cases. More than 80 of these were in real-life situations, and the rest were laboratory studies. Brain Fingerprinting testing has not made a single error in all of these cases.

How it works
1. —When someone commits a crime, his brain records it in the memory.
—2. Brain Fingerprinting reveal that memory, by showing the suspect evidence taken from the crime scene.
—3. A head band with EEG sensors is placed on the subject.

4. —A series of pictures or words, is flashed on the screen.
—5. The computer records the brain waves produced in response to what the subject sees.
—6. The brain responses called a P300 MERMER (Memory and Encoding Related Multifaceted Electroencephalographic Response), are recorded with EEG sensors as a waveform.
—7. The response is recorded in fractions of a second after the stimulus is presented, before the subject is able to formulate or control a response.
—8. By analyzing MERMER (Memory and Encoding Related Multifaceted Electroencephalographic Response) the pattern of waves, it can be determined if the subject is recognizing what he is seeing.

Stimuli Used:
—Three types of stimuli are presented:
i.) Targets: stimuli that are relevant to the investigated situation and are known to the subject.
ii.) Irrelevant: stimuli that are irrelevant to the investigated situation and not known to the test subject.
iii.) Probes: stimuli that are relevant to the investigated situation and that the subject denies knowing.

Response:

Applications:

1.National Security:
         —Identify terrorists and accomplices prior to attacks by determining whether specific information is embedded in the memory of the subject.

2.Advertising:
—Brain fingerprinting allows advertisers to determine:

• What information from an ad is retained in memory?
• —What elements do people pay attention to?
• —What type of media is most effective?
• —How to advertise to people all over the world?

3. Medical Diagnosis:
—Alzheimer’s Disease

• —Detects P300 brainwave
• —Symptoms reversible through dietary and medicinal changes

—Pharmaceutical companies

• —See effects of new medication
• —Doctors can monitor treatments and adjust them

Limitations:

• —It does not detect how that information got there.
• ——Brain fingerprinting detects only information, and not intent.
• ——It is not useful if authorities have no information about what crime have taken place.
