Police should be banned from using it in public spaces, the researchers say:
Use of live facial recognition (LFR) by UK police forces "fail[s] to meet the minimum ethical and legal standards," according to a study from the University of Cambridge. After analyzing LFR use by the Metropolitan (Met) and South Wales police, researchers concluded that the technology should be banned for use in "all public spaces."
LFR pairs faces captured by security cameras to database photos to find matches. China and other non-democratic regimes have used the technology to as part of their state surveillance tools.
[...] The Met has claimed that the latest algorithms have improved LRF accuracy, with false alerts less than .08 percent, according to The Guardian. They boasted of a 70 percent success rate up to 2020, but an expert from the University of Essex hired by the police force found it was actually just 19 percent. "That the court of appeal explicitly stated in 2020 that South Wales police use of this technology was 'unlawful' makes it difficult to argue this technology should be used," he said.
