Gujarat forensic department gets high-tech system to read criminal's brain

In an innovative stride, Gujarat's forensic science experts are set to harness the power of images to unravel complex mysteries. As per a TOI report, the acquisition of a cutting-edge Brain Electrical Oscillation Signature (BEOS) system, named the BEOS Image Classifier (BIC), is set to revolutionize investigations. This system, aimed at screening suspects and assisting investigators, has been hailed as a breakthrough by experts.

The Directorate of Forensic Sciences (DFS) in Gujarat proudly claims the distinction of being the first forensic science laboratory in India to integrate the BIC facility into its operations, as shared by DFS officials. The BEOS methodology, long used as a non-invasive means of uncovering insights into events under scrutiny, is the backbone of this novel approach.

H P Sanghvi, the director of DFS Gujarat, told TOI, "The system, while still in widespread use, works on auditory cues where facts are played back to the person being tested. If the person knows about what they hear, the brain activity indicates familiarity or vice versa"


Sanghvi said the system introduces a fresh dimension by utilizing sequences of images, both real-world and controlled. This unique feature proves advantageous in situations involving language barriers, ensuring that comprehension of the input language is not a prerequisite.

The system is currently undergoing calibration and operates in tandem with traditional BEOS techniques to validate outcomes. "The results have been encouraging thus far. Human involvement is minimal, limited to providing prompts. BEOS signatures are automatically recorded and subsequently interpreted by experts," Sanghvi asserted.

The application of BEOS typically serves as supplementary evidence or a pathway to unexplored leads in investigations. An authoritative figure from DFS highlighted the brain's capacity to retain information linked to every personal experience. Consequently, when presented with familiar cues, the brain's stored knowledge is triggered and reflected in the recorded activities.

"In the visual rendition of cues, elements like potential accomplices, locations of interest, routes taken, objects or weapons employed, among others, find representation. Visual cues prove invaluable when names, identities, or locations remain elusive, but a visual connection persists," the official elaborated.

This pioneering step by Gujarat's forensic experts marks a significant advancement in investigative techniques. The fusion of image-based analysis with brain oscillations promises to unravel mysteries that words alone might not fully convey.
