AS SKIERS SCHUSSED AND SWERVED in a snow park outside Beijing during the 2022 Winter Olympics, a few may have noticed a string of towers along the way. Did they know that those towers were collecting wavelengths across the spectrum and scouring the data for signs of suspicious movement? Did they care that they were the involuntary subjects of an Internet of Things–based experiment in border surveillance?

This summer, at the Paris Olympic Games, security officials will perform a much bigger experiment in the heart of the City of Light, covering the events, the entire Olympic village, and the connecting roads and rails. It will proceed under a temporary law allowing automated surveillance systems to detect “predetermined events” of the sort that might lead to terrorist attacks.

The Cyberspace Administration of China (CAC) would like your opinion on how it should regulate facial recognition. The agency issued draft rules on 8 August with a one-month comment period. The rules follow several years of court battles over private companies’ widespread use of the technology: Public toilets and zoos have sparked debate and lawsuits over their use of facial-recognition technology.

However, the main driver of the tech so far may be public security forces, according to recent studies. And even under the new rules, security forces will not need permission to identify individuals with facial recognition. Indeed, while people may find it humorous or galling when a toilet paper dispenser requires facial recognition, a police force’s use of facial recognition to identify protestors and quell local protests is a more weighty and controversial matter.
