To bolster national security and enhance real-time monitoring, India is integrating facial recognition technology from six major airports—Delhi, Mumbai, Bengaluru, Hyderabad, Chennai, and Kolkata—into the National Intelligence Grid (Natgrid). According to Praveer Ranjan, Director-General of the Central Industrial Security Force (CISF), this initiative links airport feeds with a massive network of 150,000 surveillance cameras across critical installations. By centralizing data from driving licenses, banking records, travel histories, and even social media, the government aims to provide law enforcement with a robust command-and-control system to track suspects and manage security threats more efficiently across its vast infrastructure.

Parallel to these security measures, India is rapidly expanding its "DigiYatra" biometric system to streamline passenger travel. This facial recognition-based platform, which has already facilitated over 100 million domestic journeys, allows travelers to bypass traditional document checks by using Aadhaar-verified selfies. With passenger traffic in India expected to hit one billion by 2040, the government plans to scale the technology to 27 additional airports next year. While this digital push is designed to create a contactless, paperless, and time-efficient travel experience, it simultaneously serves as a foundational layer for the country's broader surveillance and intelligence-sharing capabilities.
