Abstract: Developed by Dr. Lawrence Farwell, the brain fingerprinting scheme has become the most reliable and accurate lie detectors, surpassing the polygraph test. It is based on the theory which states that; while a criminal act is being committed there may or may not be any electronic devices present, however, the brain is undoubtedly always present and it takes part planning, executing and recording the crime. The Brain Fingerprinting design employs electroencephalography (EEG) in order to find it whether certain information is stored in the suspect’s brain by measuring a brain response called P300-MERMER. This paper will give you a detailed insight on the process of brain fingerprinting, which will include the theory and how it is practiced

The polygraph tests would measure the heart rates and certain stimuli and then calculated whether the person was lying or telling the truth. The polygraph tests were meddlesome as some people could lie easily without getting caught. Hence came the introduction of the Brain fingerprinting test. It is a more accurate and more modern technology to detect lies. To have a greater and more understanding insight on this method we must know the difference between the guilty and innocent. Brain fingerprinting is a test of whether the details are present in the memory or not. Therefore, the guilty, since he has committed the crime, would always have details present in the memory but the innocent would not. We should remember that the Brain Fingerprinting test does not check for any other stimuli such as heart rate or …show more content…
There are four stages in Brain Fingerprinting:
• Brain Fingerprinting Crime Scene Evidence Collection: In this first stage an expert in Brain Fingerprinting examines the crime scene and other evidence connected with the crime to identify detail of the crime that would only be known to the perpetrator.
• Brain Fingerprinting Brain Evidence Collection: In this stage the expert determines whether or not evidence from the crime scene matches the evidence in the suspects’ brain.
• Brain Fingerprinting Computer Evidence Analysis: At this stage, the Brain Fingerprinting system makes a mathematical diagnosis as to whether specific evidence is stored in the brain or not. It also computes a statistical confidence for that determination.
• Brain Fingerprinting Scientific Result: This determination and statistical confidence constitute the scientific result of Farwell brain fingerprinting: either "information present" – the details of the crime are stored in the brain of the suspect – or "information absent" – the details of the crime are not stored in the brain of the
