Neuro Signature System

“Neuro Signature System” (N.S.S.) used for “Brain Electrical Oscillation Signature Profiling”

 Overview

                 In more recent years a lot of importance has been given to forensic tools to aid in criminal investigation, and there is wide spread research interest in developing such techniques. The investigative technique being used needs to be fool proof, tamper proof, and with a sense of urgency needs to provide accurate results to aid investigations. Deception detection in suspects has become an important need in crime investigation. Current research focus is on developing technologies which can directly access information stored in the brain by measuring neural activation of the brain.

                 This is where the “Neuro Signature System” used for “Brain Electrical Oscillations Signature” Profiling comes into action, and it has proven itself in a number of criminal cases in India. “Brain Electrical Oscillations Signature” (B.E.O.S.) Profiling opens a new chapter in search of innovations for extraction of information from the brain-mind. It has helped investigators, providing them first hand information from the memory of a person to help understand if he or she was involved in a particular crime/incident, or if they were just witness to it. The technology called “Neuro Signature Profiling” was developed by Prof. C.R. Mukundan and is under patent application and hence the details of the technology are not yet published. However, extensive laboratory based and ecological validation studies have already been completed which have validated the usefulness of the test for forensic and medical applications.  

                    This is the first technique invented, which has denounced the deception detection methodology, and focused on the presence of experientially acquired knowledge/information in a person, differentiating experiential knowledge from conceptual knowledge. Further, the subject is not presented with questions that need to be answered or responded. The subject remains silent during the testing protocol.

                     The technique is based on his original finding that during awareness of past actions (autobiographical memory), the brain produces typical electrical oscillations, which form a 'Signature' of the awareness or process related to retrieval of experience. Axxonet developed the software under license from Prof. C.R. Mukundan, who conceptualized and developed the electrophysiological algorithm of the relevant neural process. Axxonet also manufactures the hardware required for the application of the technology. The technology development comprised of development of Probe Designing Methods, equipments, control programs, signal processing and analyses programs, requiring invention of new methods.

                  The Neuro Signature Systems are presently being used in various Government agencies across India. The technique has also been presented at many international and national conferences.
