AI, facial recognition tech front and centre at China security expo

AI tech that spots “undesirable” behaviour and long-distance facial recognition software were on show Thursday at a Beijing expo attended by hundreds of companies — many blacklisted by the United States for their alleged role in repression in China and abroad.

The three-day Security China event bills itself as a showcase of the future of high-tech policing and is backed by Beijing’s commerce ministry and law enforcement bodies.
