Sainsbury's said: 'This was not an issue with the facial recognition technology in use but a case of the wrong person being approached in store.' Man misidentified by London supermarket using Facewatch system says: 'I shouldn't have to prove I am not a criminal' A man was ordered to leave a supermarket in London after staff misidentified him using controversial new facial recognition technology. Warren Rajah was told to abandon his shopping and leave the local store he has been using for a number of years after an "Orwellian" error in a Sainsbury's in Elephant and Castle, London. He said supermarket staff were unable to explain why he was being told to leave, and would only direct him to a QR code leading to the website of the firm Facewatch, which the retailer has hired to run facial recognition in some of its stores. He said when he contacted Facewatch, he was told to send in a picture of himself and a photograph of his passport before the firm confirmed it had no record of him on its database. "One of the reasons I was angry was because I shouldn't have to prove I am innocent," Rajah said.

In his classic novel, 1984, George Orwell imagined how Britain might one day become a totalitarian surveillance state. Yet as Orwell's novel celebrates its 75th anniversary this month, British police are already deploying technologies that would put Big Brother to shame. From the facial recognition cameras watching you shop to the algorithms predicting crimes before they happen, these tools feel as if they've been ripped from the pages of science fiction. But there is nothing fictional about the AI cops already patrolling Britain's streets - and experts say there is only more to come. Jake Hufurt, head of research and investigations at Big Brother Watch, warned MailOnline: 'We're sleepwalking into a high-tech police state.'

The recently-departed watchdog in charge of monitoring facial recognition technology has joined the private firm he controversially approved, paving the way for the mass roll-out of biometric surveillance cameras in high streets across the country. In a move critics have dubbed an "outrageous conflict of interest", Professor Fraser Sampson, former biometrics and surveillance camera commissioner, has joined Facewatch as a non-executive director. Sampson left his watchdog role on 31 October, with Companies House records showing he was registered as a company director at Facewatch the following day, 1 November. Campaigners claim this might mean he was negotiating his Facewatch contract while in post, and have urged the advisory committee on business appointments to investigate if it may have "compromised his work in public office". It is understood that the committee is currently considering the issue.

Apple's Face ID converts your face to a set of numbers that act as your own unique identifier. This biometric portrait is not set in stone – it uses AI to track changes in your appearance, updating its model if you grow a beard, change your makeup style or get older, and it also detects whether your eyes are open and your attention is directed to your phone. Many of the iPhone's core functions are AI-enhanced. The photo app can blur backgrounds and artificially alter lighting to create the illusion of a studio photoshoot, and uses computer vision to recognise people and objects and categorise images into themes and locations. Siri uses natural language processing and machine learning to interpret your voice requests.

Senior officials at the Home Office secretly lobbied the UK's independent privacy regulator to act "favourably" towards a private firm keen to roll out controversial facial recognition technology across the country, according to internal government emails seen by the Observer. Correspondence reveals that the Home Office wrote to the Information Commissioner's Office (ICO) warning that policing minister, Chris Philp, would "write to your commissioner" if the regulator's investigation into Facewatch – whose facial recognition cameras have provoked huge opposition after being installed in shops – was not positive towards the firm. An official from the Home Office's data and identity directorate warned the ICO: "If you are about to do something imminently in Facewatch's favour then I should be able to head that off [Philp's intervention], otherwise we will just have to let it take its course." The apparent threat came two days after a closed-door meeting on 8 March between Philp, senior Home Office officials and Facewatch. Facewatch uses cameras to check faces against a watch list and, despite widespread concern over the technology, it has already been introduced in hundreds of high street shops and supermarkets.

Co-Op is facing a legal challenge to its'Orwellian' and'unlawful' use of facial recognition cameras. Privacy rights group Big Brother Watch claimed supermarket staff could add people to a secret'blacklist' without them knowing. But Co-Op says it is using the Facewatch system in shops with a history of crime, so it can protect its staff. Big Brother Watch said the independent grocery chain had installed the surveillance technology in 35 stores across Portsmouth, Bournemouth, Bristol, Brighton and Hove, Chichester, Southampton and London. It claimed staff could add individuals to a watch-list where their biometric information is kept for up to two years.

Branches of Co-op in the south of England have been using real-time facial recognition cameras to scan shoppers entering stores. This story originally appeared on WIRED UK. In total 18 shops from the Southern Co-op franchise have been using the technology in an effort to reduce shoplifting and abuse against staff. As a result of the trials, other regional Co-Op franchises are now believed to be trialing facial recognition systems. Use of facial recognition by police forces has been controversial, with the Court of Appeal ruling parts of its use to be unlawful earlier this year.

Like most retail owners, he'd had problems with shoplifting – largely carried out by a relatively small number of repeat offenders. Then a year or so ago, exasperated, he installed something called Facewatch. It's a facial-recognition system that watches people coming into the store; it has a database of "subjects of interest" (SOIs), and if it recognises one, it sends a discreet alert to the store manager. "If someone triggers the alert," says Paul, "they're approached by a member of management, and asked to leave, and most of the time they duly do." Facial recognition, in one form or another, is in the news most weeks at the moment. Recently, a novelty phone app, FaceApp, which takes your photo and ages it to show what you'll look like in a few decades, caused a public freakout when people realised it was a Russian company and decided it was using their faces for surveillance.
