"Computers once performed facial recognition rather imprecisely, by identifying people's facial features and measuring the distances among them - a crude method that did not reliably result in matches. But recently, the technology has improved significantly, because of advances in artificial intelligence. A.I. software can analyze countless photos of people's faces and learn to make impressive predictions about which images are of the same person; the more faces it inspects, the better it gets. Clearview is deploying this approach using billions of photos from the public internet. By testing legal and ethical limits around the collection and use of those images, it has become the front-runner in the field. "

"We want to start a conversation about emotion recognition technology. Explore the site, watch the video, play a game and add your thoughts to our research. Or turn on your camera to activate our very own emotion recognition machine...will it 'emojify' you? "

""Face recognition … might be the thorniest issue, where the benefits are so clear, and the risks are so clear, and we don't know where to balance those things." Excuse me? What kind of benefits could possibly balance the risk of making life extremely easy for stalkers and creeps? Well, Bosworth later said on Twitter, it could help people with prosopagnosia, a neurological condition where you can't recognize people's faces. More generally, Bosworth said, it would be super handy when you run into someone at a party and can't remember their name. Ah yes, I can totally see how avoiding a little social awkwardness balances out the whole stalker thing!"

"In a recent test of Amazon's facial recognition software, the American Civil Liberties Union of Northern California revealed that it mistook 26 California lawmakers as people arrested for crimes. "

"Prolific digital rights activism organization Fight for the Future has partnered with the group Students for Sensible Drug Policy to stop facial recognition technology from coming to college campuses. "

"The EU could temporarily ban the use of facial recognition technology in public places such as train stations, sport stadiums and shopping centres over fears about creeping surveillance of European citizens."

"A New York Times deep-dive into a facial recognition AI tool sold to law enforcement agencies uncovered that the company has amassed more than three billion images. Those images are scraped from all corners of the internet from social media sites to companies' "About Us" pages.  That's way more than the typical police or even FBI database. "

"Having mastered facial recognition for humans to an alarmingly precise degree, even picking out wanted criminals from huge crowds, Chinese tech whizzes are turning their attention to furrier faces. "We've been using it for sheep, pigs and cows," said Zhao Jinshi, who studied at Cornell University and founded Beijing Unitrace Tech, a company developing software for the agriculture industry."

"The results are unfortunately not surprising - countless studies have shown that facial recognition is susceptible to bias. A paper last fall by University of Colorado, Boulder researchers demonstrated that AI from Amazon, Clarifai, Microsoft, and others maintained accuracy rates above 95% for cisgender men and women but misidentified trans men as women 38% of the time."

"Before we go deeper, it's important to note that there are two approaches to facial - or any biometric - authentication: "match on server" and "match on device." The former approach shares some of the risky aspects of facial recognition technology because it stores the details of one's most personal features-your face or your fingerprint-on a server, which is inherently insecure. There are some well-publicized examples of biometric databases being hacked, which is why so many companies are committing to only do on-device biometrics."

""This was, you know, kind of a 'shower thought' moment for me, and just kind of an intersection of what I know how to do and what my current interests are," he said. "Accountability is important. We need to know who is doing what, so we can deal with it." Mr. Howell is not alone in his pursuit. Law enforcement has used facial recognition to identify criminals, using photos from government databases or, through a company called Clearview AI, from the public internet. But now activists around the world are turning the process around and developing tools that can unmask law enforcement in cases of misconduct."

"The gulf between how well facial recognition performs in academic settings vs. real world applications is vast."

"The Bank of Thailand has allowed six commercial banks to offer facial recognition for electronic Know Your Customer (e-KYC) technology to verify the identity of new customers under the regulatory sandbox when opening online deposit accounts."

"You're nailing the problem: the tech sales people and the politicians are all on the same drug, which is "This tech is perfect", because it's cheaper than more police. There's a lawsuit in the US because a black man was wrongly arrested based on facial recognition. Tech companies need to be held to account. One company we focused on, Clearview AI, scraped social networks - collected images of people's faces and data from publicly available information - to create its software. Facial recognition relies on artificial intelligence. It needs to study faces. And only the government - the DVLA etc - and social networking companies have access to a lot of faces."

"And some provinces are using some creepy Big Brother technology to do it. In Surat Thani, the province that contains the tourism hotspot islands of Koh Samui, Koh Phangan, and Koh Tao, the immigration office is employing new technology. Officers have equipped Smart Patrol Cars that is using advanced facial recognition to check foreigners quickly. Immigration officers are patrolling in WiFi-enabled cars, usually a BMW, to crack down on foreigners who have overstayed."

"What if facial recognition technology isn't as good at recognising faces as it has sometimes been claimed to be? If the technology is being used in the criminal justice system, and gets the identification wrong, this can cause serious problems for people (see Robert Williams' story in "Facing up to the problems of recognising faces")."

"Campaigners fear the face-scanning technology could be used against protesters, and that police have done so before. The Met insisted the technology would not be used to quell lawful protest or target activists. But campaign groups do not believe them. Britain's biggest force said: "It is not used to identify people who are linked to, or have been convicted of, being involved in protest activity." A leading academic expert said the number of people whose faces would be scanned would make it the largest deployment yet of live facial recognition (LFR) in the UK."

"Moves to ban live "Big Brother" real time facial recognition technology from being deployed across the streets of the EU or by border officials will be tested in a key vote at the European parliament on Thursday. The amendment is part of a package of proposals for the world's first artificial intelligence laws, which could result in firms being fined up to €10m (£8.7m) or removed from trading within the EU for breaches of the rules."

"Every day, nearly 5 million people use São Paulo's metro system. Every one of their faces may have been recorded in a facial recognition system that has been in use since early 2020. In a March 23 decision, a São Paulo State court ordered the Metro company to stop using the technology. The Metro appealed the decision, claiming its monitoring system "rigorously obeys the General Law on Data Protection," but the argument was rejected by the same court in mid-April."

"A new AI-infused classroom management tool with facial recognition capabilities has garnered attention recently with promises to take attendance, assess the emotional states of students, and monitor classes for distraction, boredom and confusion. But the technology and similar developments have raised numerous legal, ethical, and civil liberties questions similar to those surrounding campus safety surveillance programs and test proctoring programs widely adopted during the COVID pandemic."
