The coronavirus emergency has brought some of that technology out of the shadows, providing the authorities with a justification for sweeping methods of high tech social control.
If a coronavirus patient boards a train, the railway's "Real name" system can provide a list of people sitting nearby.
"In the era of big data and internet, the flow of each person can be clearly seen. So we are different from the SARS time now," epidemiologist Li Lanjuan said in an interview with China's state broadcaster CCTV last week, comparing the outbreak to a virus that killed 800 people in 2003.
"With such new technologies, we should make full use of them to find the source of infection and contain the source of infection."
Companies have responded with a flurry of announcements touting the capabilities of their technology.
SenseTime, another leading AI firm, said it has built a similar system to be used at building entrances, which can identify people wearing masks, overcoming a weakness of earlier technology.
Surveillance camera firm Zhejiang Dahua says it can detect fevers with infrared cameras to an accuracy within 0.3ºC. In an interview with state news agency Xinhua, Zhu Jiansheng of the China Academy of Railway Sciences explained how technology can help the authorities find people who might be exposed to a confirmed or suspected coronavirus case on a train.
