Connected sunglasses allow Chinese police to scan crowds for suspects
In February 2018, police in China began using connected sunglasses equipped with facial recognition to scan crowds looking for suspected criminals. In a test at a busy train station in the city of Zhengzhou, police were able to identify and apprehend seven suspects accused of crimes ranging from hit-and-run to human trafficking. Police also identified 26 people using fake IDs, according to the Communist Party's People's Daily Newspaper. The glasses allow police officers to take a photograph of a suspicious individual and compare it to pictures held in an internal database. If the system finds a match, identifying details such as name and address will be sent to the officer. China is a world leader in facial recognition and frequently reminds its citizens that it will make escape impossible. The country is thought to have 170 million CCTV cameras already in place, with 400 million more due to be installed between 2018 and 2021.
