Operational use of the cameras will only last for five or six hours at a time, says BBC News, but the Met makes clear that the use of this technology is to be the new normal in London.“As a modern police force, I believe that we have a duty to use new technologies to keep people safe in London,” said the Met’s assistant commissioner Nick Ephgrave said in a press statement. “Every day, our police officers are briefed about suspects they should look out for; [facial recognition] improves the effectiveness of this tactic.”
Ed Bridges, 36, brought the challenge at the High Court after claiming his face was scanned while doing Christmas shopping in 2017 and at a peaceful anti-arms protest in 2018.His lawyers argued the use of automatic facial recognition (AFR) by South Wales Police caused him 'distress' and violated his privacy and data protection rights by processing an image taken of him in public.
The use of facial recognition by law enforcement in the UK has previously been limited to small trials and public events like concerts and football matches. Such deployments have been widely criticized, with data from one trial indicating that the 81 percent of “matches” suggested by the facial recognition system were incorrect.
Despite this, the Met calls the technology “tried and tested,” and says the algorithms it uses from biometric firm NEC identify 70 percent of wanted suspects and only generate false alerts for one in every 1,000 cases.Privacy advocates described the deployment of the technology as an attack on civil liberties. The use of facial recognition around the world has been criticized by many tech experts and privacy advocates, who note such systems are often racially biased and are misused by the police. Even some big tech companies like Google now back a moratorium on the technology.
“This decision represents an enormous expansion of the surveillance state and a serious threat to civil liberties in the UK,” Silkie Carlo, director of Big Brother Watch, told The Daily Mail. “This is a breath-taking assault on our rights and we will challenge it, including by urgently considering next steps in our ongoing legal claim against the Met and the Home Secretary. This move instantly stains the new Government’s human rights record and we urge an immediate reconsideration.”
