London Police’s Face Recognition System Gets It Wrong 81 Percent of the Time

An anonymous reader quotes a report from MIT Technology Review: London’s police force has conducted 10 trials of face recognition since 2016, using Japanese company NEC’s Neoface technology. It commissioned academics from the University of Essex to independently assess the scheme, and they concluded that the system is 81% inaccurate (in other words, the vast majority of people it flags for the police are not on a wanted list). They found that of 42 matches, only eight were confirmed to be correct, Sky News reports. The Met police insists its technology makes an error in only one in 1,000 instances, but it hasn’t shared its methodology for arriving at that statistic.
