ABSTRACT
A brain computer interaction has been developed to record the brain signal / electric activity through Digital
Electroencephalography. The Brain Fingerprinting is a advanced computer-based technology to determine the
falsely accused innocent suspects of a crime accurately and scientifically by measuring brain-wave responses to
crime-relevant words or pictures presented on a computer screen. By using electroencephalography to ascertain
the presence or absence of information into human brain.
Introduction
The primary application of the brain computer interface is to map the brain signal of human being through
digital EEG[1]. Basically the happened incidents in our life has to be recorded / stored into our mind. If
someone required to know that incidents , it could be possible by applying a standard technique brain finger
printing through digital electroencephalograph.
Brain Fingerprinting technique used to determine mapped signal, what information is, or is not stored in a
particular brain[2]. Not a measure of guilt or innocence, Measures the response to visual or audio stimulus.
Actually this technology is based on the principle that the brain is central to all human acts. In a criminal act,
there may or may not be many kinds of peripheral , but the brain is always with planning, executing, and
recording crime. The fundamental difference between a true or and falsely accused, innocent person is that
the perpetrator, having committed the crime, has the details of the crime stored in his brain, and the innocent
suspect does not
The secrets of Brain Fingerprinting
“Matching the happened incident at the crime scene with incidence in the brain” .When a crime is committed, a
record is stored in the brain of the perpetrator. Brain Fingerprinting provides a means to objectively and
scientifically connect facts from the crime scene with incidence stored in the brain. Brain Fingerprinting
measures electrical brain activity on computer / laptop screen regarding crime-investigation. when and only
when , the things stored in the brain matches the happened things from the crime scene[3]. Thus, the guilty can
be identified and the innocent can be cleared in an accurate, scientific, objective, non-invasive, non-stressful. A
memory and encoding related multifaceted electroencephalographic response is elicited when an individual
recognizes and processes an incoming stimulus that is significant or noteworthy[4]. The procedure used is
similar to the Guilty Knowledge Test; a sequences/ combination of words, sounds, or pictures are presented via
computer to the subject for a fraction of a second each. When an irrelevant stimulus is seen, it is insignificant
and not noteworthy, and the electrode response is absent. The electrodes response occurs within a second after
Phases of Brain Fingerprinting
Brain Fingerprinting works similarly, except that the happened incident collected both at the crime scene and on
the person of the suspect (i.e., in the brain as revealed by electrical brain responses) is informational facts rather
than physical happened incident[5]. There are four stages to Brain Fingerprinting as:
Computer Controlled System
Nowadays every thing is based on the computer and treating as a human computer interface means behind the
each and every successful technology , business , science , arts , commerce field computer is playing a most
important role by controlling the device ,machine as a natural way[6]. The entire Brain Fingerprinting System is
under computer control, including presentation of the stimuli and recording of electrical brain activity, as well as
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", and a statistical confidence level for this
determination[7]. At no time during the testing and data analysis do any biases and interpretations of a system
expert affect the stimulus presentation or brain responses.
APPLICATIONS
PPLICATIONS:
1) National security: To Identify terrorists , fugitives, criminals and accomplices prior to attack by
determining whether specific information is embedded into brain memory of the subject.
2) Medical diagnosis :
a) Alzheimer’s Disease : detects p300 brainwave, symptoms reversible through dietary and medicinal
changes.
b) Pharmaceutical companies: to see effects of new medication, doctors can monitor treatments and
adjust them.
3) Advertising :
It allow advertisers to determine what information from an ad is retained in memory as (i) what elements do
people pay attention to .(ii) what type of media is most effective . (iii) how to people all over the world.
Cons of Brain fingerprinting Tech : a) very Costly b) available at few specific Laboratories only.
c) used to solve complex and important criminal cases only.
Conclusion
Brain Fingerprinting technology is a advanced brain computer interface technology for solving the criminals
case and also identify the perpetrators, and exonerating innocent suspects. This technology provide the 99.9%
accurate result towards crime victims, falsely accused innocent suspects.
