India has just 144 police officers for every 100,000 citizens. In recent years, authorities have turned to facial recognition technology to make up for the shortfall. India's government now ... wants to construct one of the world's largest facial recognition systems. The project envisions a future in which police from across the country's 29 states and seven union territories would have access to a single, centralized database. The daunting scope of the proposed network is laid out in a detailed 172-page document published by the National Crime Records Bureau, which requests bids from companies to build the project. The project would match images from the country's growing network of CCTV cameras against a database encompassing mug shots of criminals, passport photos and images collected by [government] agencies. It would also recognize faces on closed-circuit cameras and generate alerts if a blacklist match is found." Security forces would be equipped with hand-held mobile devices enabling them to capture a face in the field and search it instantly against the national database, through a dedicated app. For privacy advocates, this is worrying. "India does not have a data protection law," says [Apar] Gupta [of the Internet Freedom Foundation]. "It will essentially be devoid of safeguards." It might even be linked up to Aadhaar, India's vast biometric database, which contains the personal details of 1.2 billion Indian citizens, enabling India to set up "a total, permanent surveillance state," he adds.
