  • 1. Brain Fingerprinting
  • 2. Introduction
    • Brain Fingerprinting is a new computer-based technology to identify the perpetrator of a crime accurately and scientifically by measuring brain-wave responses to crime-relevant words or pictures presented on a computer screen.
    • Brain fingerprinting was invented Dr.Lawrence Farwell .
    • Brain Fingerprinting is based on the principle that the brain is central to all human acts.
    • Brain Fingerprinting has proven 100% accurate in over 120 tests, including tests on FBI agents, tests for a US intelligence agency and for the US Navy.
  • 4. Techniques
    • The technique uses the well known electrical signal known as P300.
    • The novel interpretation in brain fingerprinting is to look for P300 as response to stimuli related to the crime in question.
    • Because it is based on EEG signals, the system does not require the person to issue verbal responses to questions or stimuli.
  • 5. Informational Evidence Detection
    • This new system detects information directly, on the basis of the electrophysiological manifestations of information-processing brain activity, measured non-invasively from the scalp.
    • Since Brain Fingerprinting depends only on brain information processing, it does not depend on the emotional response of the subject.
  • 6. . The Brain MERMER
    • Brain Fingerprinting utilizes multifaceted electroencephalographic response analysis (MERA) to detect information stored in the human brain.
    • A memory and encoding related electroencephalographic response (MERMER) is elicited when an individual recognizes and processes an incoming stimulus that is significant or noteworthy.
    • The MERMER occurs within about a second after the stimulus presentation, and can be readily detected using EEG amplifiers.
  • 7. . Waveform analysis
  • 8. . Scientific Procedure
    • A sequence of words or pictures is presented on a video monitor under computer control.
    • Each stimulus appears for a fraction of a second.
    • Three types of stimuli are presented: "targets," "irrelevant," and "probes."
  • 9. . Scientific Procedure
    • Target : The target stimuli are made relevant and noteworthy to all subjects.
    • Irrelevant : These have no relation to the situation under investigation.
    • Probes : Probes are the stimuli that are relevant to the situation under investigation.
  • 10. Using BRAIN WAVES To Detect GUILT
  • 11. . Computer Controlled
    • The entire Brain Fingerprinting System is under computer control, including presentation of the stimuli and recording of electrical brain activity.
    • It has 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“ .
    • A statistical confidence level can be determined.
  • 12. P hases of Brain Fingerprinting
    • 1. Information Collection.
    • 2. Brain Evidence Collection.
    • 3. Computer Evidence Analysis.
    • 4. Scientific Result .
  • 13. Devices Used
  • 14.  
  • 15. Result Analysis
  • 16. Applications
    • Criminal Justice
    • Medical
    • Security purposes
  • 17. Advantages
    • Brain Fingerprinting has been thoroughly and scientifically tested.
    • The rate of error is extremely low -- virtually nonexistent -- and clear standards governing
    • Scientific techniques of operation of the technology have been established and published.
    • Record of 100% accuracy
  • 18. C onclusion
    • Brain Fingerprinting is a revolutionary new scientific technology for solving crimes, identifying perpetrators.
    • If research determines that brain MERMER testing is reliable enough that it could be introduced as evidence in court.
    • It may be the criminal investigative tool of the future.
