The New York Times tells the story of Simon Mackenzie, a security officer at a U.K. discount store uploading security camera footage of shoplifters into a facial recognition program called Facewatch. "The next time those people enter any shop within a few miles that uses Facewatch, store staff will receive an alert." Facewatch — now in nearly 400 stores across Britain — licenses facial recognition software made by Real Networks and Amazon. Though it only sends alert about repeat offenders, "Once added, a person remains there for a year before being deleted." For as little as 250 pounds a month, or roughly $320, Facewatch offers access to a customized watchlist that stores near one another share. When Facewatch spots a flagged face, an alert is sent to a smartphone at the shop, where employees decide whether to keep a close eye on the person or ask the person to leave. Mr. Mackenzie adds one or two new faces every week, he said, mainly people who steal diapers, groceries, pet supplies and other low-cost goods. He said their economic hardship made him sympathetic, but that the number of thefts had gotten so out of hand that facial recognition was needed. Usually at least once a day, Facewatch alerts him that somebody on the watchlist has entered the store... Among democratic nations, Britain is at the forefront of using live facial recognition, with courts and regulators signing off on its use. The police in London and Cardiff are experimenting with the technology to identify wanted criminals as they walk down the street. In May, it was used to scan the crowds at the coronation of King Charles III. But the use by retailers has drawn criticism as a disproportionate solution for minor crimes. Individuals have little way of knowing they are on the watchlist or how to appeal. In a legal complaint last year, Big Brother Watch, a civil society group, called it "Orwellian in the extreme...." Madeleine Stone, the legal and policy officer for Big Brother Watch, said Facewatch was "normalizing airport-style security checks for everyday activities like buying a pint of milk." There is a human in the loop, the article points out. "Every time Facewatch's system identifies a shoplifter, a notification goes to a person who passed a test to be a 'super recognizer' — someone with a special talent for remembering faces. Within seconds, the super recognizer must confirm the match against the Facewatch database before an alert is sent." The company's founder tells the Times that in general, "mistakes are rare but do happen... If this occurs, we acknowledge our mistake, apologize, delete any relevant data to prevent reoccurrence and offer proportionate compensation." And the article adds this official response from the U.K. government: Fraser Sampson, Britain's biometrics and surveillance camera commissioner, who advises the government on policy, said there was "a nervousness and a hesitancy" around facial recognition technology because of privacy concerns and poorly performing algorithms in the past. "But I think in terms of speed, scale, accuracy and cost, facial recognition technology can in some areas, you know, literally be a game changer," he said. "That means its arrival and deployment is probably inevitable. It's just a case of when."
