Brain Fingerprinting Technology Contents: ● Introduction ● Definition ● Equipment and technology ● Computer Controlled ● Technique ● Comparison with other technologies ● Role in criminal proceedings ● Applications ● Advantages ● Disadvantages ● Conclusion Equipment and technology: The brain fingerprinting system comprises:- 1. A personal computer. 2. A data acquisition board. 3. Two monitors. 4. A EEG amplifier. 5. Software for data acquisition Some electrodes. Computer Controlled: The electrodes to used to measure electrical brain activity. The software presents the stimuli, collects the EEG data, and analyzes the data. Brain electrical activity amplified and stored on a memory device. During the data collection ,the stimuli are displayed to the subject on one monitor, and the investigator views another monitor. Technique: When someone commits a crime, his brain records it has a memory . Brain Fingerprinting seeks to reveal that memory, by showing the suspect evidence taken from the crime scene. Brain of the perpetrator is the store house of Experiential knowledge Because perpetrator experiences the crime Though experience is subjective, it is the closest indicator of objective reality Experiential knowledge is unique and different compared to the semantic and conceptual knowledge A head band with sensors is placed on the subject. A series of pictures or words is flashed on the screen. The computer records the brain waves produced in response to what the subject sees. Electroencephalography: Electroencephalography (EEG) is the measurement of electrical activity produced by the brain as recorded from electrodes placed on the scalp. So-called scalp EEG is collected from tens to hundreds of electrodes positioned on different locations at the surface of the head. EEG signals (in the range of mille-volts) are amplified and digitalized for later processing. The data measured by the scalp EEG are used for clinical and research purposes. Role In Criminal Proceedings: The application of Brain Fingerprinting testing in a criminal case involves four phases: 1. Investigation 2. Interview 3. Scientific testing and 4. Adjudication. The first phase is undertaken by a skilled investigator, the second by an interviewer who may be an investigator or a scientist, the third by a scientist, and the fourth by a judge and jury. Continued…. ● PHASE 1: Investigation Before a brain fingerprinting testing can be applied, an investigation must be undertaken to discover information that can be used in the test. ● PHASE 2: Interview of Subject Once evidence has been accumulated through investigation, the interview with the suspect may help to determine which scientific tests to conduct, or how to conduct the tests. Detection in BFT ► Brain Fingerprinting scientifically detects whether specific information is stored in the brain by measuring brainwaves. Brainwave Science has developed and patented EEG/P300 based testing systems that determine with accuracy whether or not specific information is stored in a person's memory. ► The RED and BLUE lines are closely correlated. This indicates the subject has information PRESENT. ► If the BLUE is not going along with RED the information is ABSENT Applications: The various applications are as follows:- 1. Test for several forms of employment, especially in dealing with sensitive military and foreign intelligence screening. 2. Individuals who were “information present” and “information absent”. 3. To detect symptoms of Alzheimers disease, Mental Depression and other forms of dementia including neurological disorders. 4. Criminal cases. 5. Counter-Terrorism. 6. Security Testing. Advantages: The various advantages are as follows:- 1. The rate of error is extremely low virtually nonexistent and clear standards governing. 2. Record of 100% accuracy. 3. Identifies the criminal quickly and scientifically. 4. Provides immediate scientific result. 5. Reduced costs and complexities. 6. Support the right to a speedy and fair trail.
