  1. 1. The Brain Fingerprinting Technology 1
  2. 2. ABSTRACTBrain Fingerprinting is a new computer-based technology toidentify the perpetrator of a crime accurately and scientificallyby measuring brain-wave responses to crime-relevant words orpictures presented on a computer screen. Brain Fingerprintinghas proven 100% accurate in over 120 tests, including tests onFBI agents, tests for a US intelligence agency and for the USNavy, and tests on real-life situations including felony crimes.Why Brain Fingerprinting??? Brain Fingerprinting is based on the principle that the brain iscentral to all human acts. In a criminal act, there may or may notbe many kinds of peripheral evidence, but the brain is alwaysthere, planning, executing, and recording the crime. Thefundamental difference between a perpetrator and a falselyaccused, innocent person is that the perpetrator, havingcommitted the crime, has the details of the crime stored in hisbrain, and the innocent suspect does not. This is what BrainFingerprinting detects scientifically. 2
