If you're reading this in the United States, there's a 50 percent chance that a photo of your face is in at least one database used in police facial-recognition systems. Police departments in nearly half of U.S. states can use facial-recognition software to compare surveillance images with databases of ID photos or mugshots. Some departments only use facial-recognition to confirm the identity of a suspect who's been detained; others continuously analyze footage from surveillance cameras to determine exactly who is walking by at any particular moment. Altogether, more than 117 million American adults are subject to face-scanning systems. These findings were published Tuesday in a report from Georgetown Law's Center for Privacy and Technology.
Microsoft claims its facial recognition technology just got a little less awful. Earlier this year, a study by MIT researchers found that tools from IBM, Microsoft, and Chinese company Megvii could correctly identify light-skinned men with 99-percent accuracy. But it incorrectly identified darker-skinned women as often as one-third of the time. Now imagine a computer incorrectly flagging an image at an airport or in a police database, and you can see how dangerous those errors could be. Microsoft's software performed poorly in the study.
Facial recognition technology used by the UK police is making thousands of mistakes - and now there could be legal repercussions. Civil liberties group, Big Brother Watch, has teamed up with Baroness Jenny Jones to ask the government and the Met to stop using the technology. They claim the use of facial recognition has proven to be'dangerously authoritarian', inaccurate and a breach if rights protecting privacy and freedom of expression. If their request is rejected, the group says it will take the case to court in what will be the first legal challenge of its kind. South Wales Police, London's Met and Leicestershire are all trialling automated facial recognition systems in public places to identify wanted criminals.
OSAKA – Despite advances in facial recognition technology, the police in Osaka still rely on pure skill to find fugitives, with investigators using only their memory to arrest dozens of wanted criminals every year. While other police forces in the world have "super recognizer" units that hunt down fugitives, the so-called miatari (look and hit) technique used in Osaka has contributed to the arrests of over 4,000 criminals in Japan since the Osaka Prefectural Police introduced it as a formal investigative method in November 1978. There has not been a single wrongful arrest. "The best part of this method is being able to detect fugitives who are hard to find in normal investigations," said a senior investigator in Osaka. He says a forensic analysis is an imperative part of criminal investigations, but "we want to pass on the tradition because our job is to make sure no one gets away with a crime."
