3. Introduction Brain Fingerprinting is an investigative technique. R ecognition of familiar stimuli by measuring electrical brain wave. R esponses towards, phrases, or pictures that are presented on a computer screen. 2-May-24 3

4. The need.. 2-May-24 4

5. History 2-May-24 5

6. P300 2-May-24 6

7. Mermer Methodology 2-May-24 7

8. TECHNIQUE The person to be tested wears a special headband with electronic sensors The testee is presented with a series of relevant and irrelevant stimuli. Analysis of the relevant and irrelevant stimuli. 2-May-24 8

9. Picture/word shown to an individual (Stimulus) Triggers neurons of brain Generates brainwave (P300) Electrical Potentials Accumulate in brain (MERMER) Headgear fitted with Electrodes placed on scalp P300 –MERMER (an scalp ERP EEG) Measures brainwaves Generates analog signals EEG amplifier Study the data Using a computer program Found Guilty/ Not guilty 2-May-24 9

12. Working Principle A Suspect is tested by looking at three kinds of information represented by Different coloured lines: ----- Red: information the suspect is expected to know ----- Green: information not known to suspect ----- Blue: information of the crime that only perpetrator would know 2-May-24 12

13. 2-May-24 13 NOT GUILTY: Because the blue and green lines closely correlate, suspect does not critical knowledge of the crime GUILTY: Because the blue and red lines closely correlate, and suspect does have critical knowledge of the crime.

14. Results of the Brain Fingerprinting test on Terry Harrington For the test on Schweer's murder, the determination of Brain Fingerprinting was "information absent," with a statistical confidence of 99.9%. The information stored in Harrington's brain did not match the scenario in which Harrington went to the crime scene and committed the murder 2-May-24 14

15. Results of the Brain Fingerprinting test on Terry Harrington The determination of the Brain Fingerprinting test for alibi-relevant information was "information present,“ with a confidence of 99.9%. The information stored in Harrington's brain did match the scenario in which Harrington was elsewhere (at a concert and with friends) at the time of the crime. 2-May-24 15

17. ADVANTAGES 2-May-24 17

18. Limitations Brain fingerprinting detects information-processing brain responses that reveal what information is stored in the subject's brain. It does not detect how that information got there.  Brain fingerprinting does not detect lies. It simply detects information. No questions are asked or answered during a brain fingerprinting test. 2-May-24 18

19. CONCLUSION Brain Fingerprinting is a revolutionary new scientific technology for solving crimes, identifying perpetrators, and exonerating innocent suspects With a record of 100% accuracy in research with US government agencies, actual criminal cases, and other applications. The technology fulfils an urgent need for governments, law enforcement agencies, corporations, investigators, crime victims, and falsely accused innocent suspects. 2-May-24 19
