India is trying to build the world's biggest facial recognition system

India has just 144 police officers for every 100,000 citizens, compared to 318 per 100,000 citizens in the European Union. In recent years, authorities have turned to facial recognition technology to make up for the shortfall. New Delhi's law enforcement agencies adopted the technology in 2018, and it's also being used to police large events and fight crime in a handful of other states, including Andhra Pradesh and Punjab. But India's government now has a much more ambitious plan. It wants to construct one of the world's largest facial recognition systems.
