Liu Tianyi, at LLVision, the firm that developed the GLXSS Pro smart glasses, says the glasses are so light that the police officers can wear them all day. The special glasses are currently being used by four officers patrolling a crowded train station in Zhengzhou, Henan province during Chinese New Year, the busiest time for the country’s transport system. More than 389 million train trips are likely to be made between the peak period of February 1 and March 12, which is when people return home for holidays The glasses have a small camera attached to a smartphone-like device that allows the officers to take photos of suspicious individuals and run the headshot in their database. Using the technology, the database can in real time provide individual’s personal details, including name, ethnicity, gender, address and criminal records. All the information would be transferred back to the officer’s glasses. It also informs officers whether the suspect, the hotel address where they are staying and even their recent Internet history. “The glasses — which resemble Google Glass — are connected to a police database that can match passengers with criminal suspects,” said a report in the People’s Daily online. “The facial information captured by the glasses will be sent back to a database for comparison with the information of suspects on the wanted list,” Zhang Xiaolei, an employee at the publicity office of Henan’s Department of Public Security, told the Global Times on Tuesday. With the help of these high-tech sunglasses, police at the Zhengzhou East Railway Station have nabbed 33 suspects, of which 7 are accused of human trafficking and hit and runs, while 26 are accused of using fake IDs. However, these programs have drawn strong criticism by human-rights groups and privacy advocates, who say that the implementation of this technology invades on people’s right to privacy. “Chinese authorities seem to think they can achieve ‘social stability’ by placing people under a microscope, but these abusive programs are more likely to deepen hostility towards the government,” Sophie Richardson, China director of Human Rights Watch, had previously said about different facial recognition technology being used to monitor religious minorities. “Beijing should immediately stop these programs, and destroy all data gathered without full, informed consent.”
