Brain fingerprinting

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