Electroencephalography Signal Technique
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. Keywords : Brain finger printing ,Digital EEG , BCI ,
The primary application of the brain computer interface is to map the brain signal of human being through digital EEG. 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. 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.

II 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. 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. 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 the stimulus presentation, and can be readily detected using EEG electrodes, amplifiers and a computerized signal-detection algorithm.
III 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. There are four stages to Brain Fingerprinting as:
1.Crime Scene Collection:
In this, an expert examines the crime scene and other incidents connected with the crime to identify the crime.
2. Brain Incidence Collection:
This is done to determine whether or not the incidence from the crime scene matches evidence stored in the brain of the suspect.
3.Computer -Analysis :
In this, the Brain Fingerprinting system makes a mathematical determination as to whether or not this specific incidence is stored in the brain, and computes a statistical...
