Brain fingerprinting

Brain fingerprinting is a lie detection technique which uses electroencephalography (EEG) to determine whether specific information is stored in a subject's brain. The technique consists of measuring and recording a person's electrical brainwaves and brain response when asked questions about a crime, attempting to elicit a "P300 response" that indicates familiarity with the details of the crime.[1] The technique is controversial, unproven[1] and of questionable accuracy.[2] Comparison of brain fingerprinting with polygraphy showed mixed results consistent with "a mix of proven techniques and dangerously exaggerated benefits".[1]

Brain fingerprinting was invented by Dr. Lawrence Farwell.[1] In 2001, the technique was ruled admissible for court use in Iowa by the decision in Harrington vs. State of Iowa.[3] It was also used in India,[4][5] until a 2010 Indian Supreme Court ruling. A. R. Lakshmanan, judge and past Chairman of the Law Commission of India, welcomed this ruling, describing brain fingerprinting as "so science-fictional that there were no takers anywhere else in the world".[6] In November 2015, Raksha Shakti University, Ahmedabad became the first institute in India to receive the brain fingerprinting technology[7]. In June 2016, The Times of India reported that Central Bureau of Investigation used the brain fingerprinting test, technology available at Raksha Shakti University (RSU) in Ahmedabad.[8] In June 2016, another report published in The Indian Express stated that brain Fingerprinting technology used at Raksha Shakti University was utilized in cold case of a 25 year old woman from Kerala who went missing in Dubai. The brain fingerprinting test was conducted for Central Bureau of Investigation officials following the order of the Kerala High Court. [9]
