One face, 463 cameras: Facial recognition fights crime on Mumbai rly platforms, Pg1

Key Highlights:

• The Facial Recognition System (FRS), linked to 463 CCTV cameras across 114 railway stations in Mumbai, has aided in solving crimes like harassment, missing person cases, and stabbings.
• Western Railway was the first division in India to install FRS linked to CCTV cameras, starting in 2022.
• In 2024, over 10,000 photographs of individuals tracked by agencies like NIA and CBI were uploaded into the FRS.
• The FRS identifies individuals by converting facial features into a unique numerical "faceprint".

Detailed Insights:

• The FRS-equipped CCTV system alerts authorities when a person on the watchlist is detected, triggering a chain of actions for apprehension.
• The system can map patterns in an individual’s movements, helping investigators track suspects and establish their routines.
• Even with unclear footage, the FRS can generate possible matches with varying confidence levels, aiding in investigations.
• The FRS has been crucial in tracing missing children at crowded stations like CSMT and Churchgate, providing information on their last known location.
• Mumbai Police units, operating over 5,000 cameras, are also linking FRS to their network to enhance crime-solving capabilities.
• The installation of FRS is nearing completion on the Mumbai section of Central Railways, with staff training underway.
