    Brain fingerprinting Brain fingerprinting Presentation Transcript

    • Brain Fingerprinting
    • 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.
    • 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.
    • 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.
    • . 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.
    • . Waveform analysis
    • . 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."
    • . 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.
    • Using BRAIN WAVES To Detect GUILT
    • . 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.
    • P hases of Brain Fingerprinting
      • 1. Information Collection.
      • 2. Brain Evidence Collection.
      • 3. Computer Evidence Analysis.
      • 4. Scientific Result .
    • Devices Used
    • Result Analysis
    • Applications
      • Criminal Justice
      • Medical
      • Security purposes
    • 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
    • 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.
