London police to use face scan tech, stoking privacy fears

LONDON (AP) — London police will start using facial recognition cameras to pick out suspects from street crowds in real time, in a major advance for the controversial technology that raises worries about automated surveillance and erosion of privacy rights.

The Metropolitan Police Service said Friday that after a series of trials, the cameras will be put to work within a month in operational deployments of around 5-6 hours at potential crime hotspots. The locations would be chosen based on intelligence but the police did not say where, the number of places, or how many cameras would be deployed.

Real-time crowd surveillance by British police is among the more aggressive uses of facial recognition in wealthy democracies and raises questions about how the technology will enter people’s daily lives. Authorities and private companies are eager to use facial recognition but rights groups say it threatens civil liberties and represents an expansion of surveillance.

London’s decision to use the technology defies warnings from rights groups, lawmakers and independent experts, Amnesty International researcher Anna Bacciarelli said.

“Facial recognition technology poses a huge threat to human rights, including the rights to privacy, non-discrimination, freedom of expression, association and peaceful assembly,” Bacciarelli said.

London police said the facial recognition system, which runs on technology from Japan’s NEC, looks for faces in crowds to see if they match any on “watchlists” of up to 2,500 people wanted for serious and violent offences, including gun and knife crimes and child sexual exploitation.

“As a modern police force, I believe that we have a duty to use new technologies to keep people safe in London,” Assistant Commissioner Nick Ephgrave said in a statement.

The British have long become accustomed to video surveillance, with cameras used in public spaces for decades by security forces fighting terror threats. Real-time monitoring will put that tolerance to the test.

London is the sixth most monitored city in the world, with nearly 628,000 surveillance cameras, according to a report by Comparitech.

London’s move comes after a British High Court ruling last year cleared a similar deployment by South Wales police, which has been using it since 2017 to monitor big events like soccer games, royal visits and airshows. That system deleted people’s biometric data automatically after scanning.

Britain’s privacy commissioner, Elizabeth Denham, who had warned police not to take that ruling as a blanket approval, struck a cautious tone on Friday.

She said that while London police have stated they’re putting safeguards and transparency in place to protect privacy and human rights, “it is difficult to comment further on this until we have an actual deployment and we are able to scrutinize the details of that deployment.”

Signs will warn passersby about the cameras and officers will pass out leaflets with more information, the police said, adding that the system isn’t linked to any other surveillance systems.

London police previously carried out a series of trial deployments that they say identified 7 out of 10 wanted suspects who walked past the camera while only incorrectly flagging up 1 in 1,000 people. But an independent review last year by University of Essex professors questioned that, saying the trials raised concerns about their legal basis and the equipment’s accuracy, with only 8 of 42 matches verified as correct.

Pete Fussey, a University of Essex professor who co-authored the report, said NEC has upgraded its algorithm since then, but there’s evidence that the technology isn’t 100% accurate, pointing to a recent U.S. government lab’s test of nearly 200 algorithms that found most have ethnic bias.

“If you’re using the algorithm you should be aware of its shortcomings,” he said. “It’s vanishingly unlikely that NEC’s algorithm will be effective across all ethnic categories.”

Ring beefs up its security with mandatory 2FA, suspends third-party trackers in mobile app

Amazon’s Ring has had a rough couple of months when it comes to privacy and security, but we all may be better off as a result. Starting today, Ring is taking two big steps toward assuring customers that their accounts safe from hackers and prying eyes.

First off, Ring is making two-factor authentication mandatory for all users. That means that users will be required to verify their account with a six-digit code when signing in to their account on a new device. By sending a code to one of your trusted devices, you will know if someone other than you is trying to access your account remotely, and you can change your password.

When you or someone else sign into your Ring account using 2fA, you’ll get an email that looks like this.

Codes can either be delivered via text (SMS) or email. Hopefully Ring will add authenticator apps and security keys in a future update.

Ring will also be beefing up its privacy via its new Control Center. Users can now opt out of sharing information with third-party advertisers. The new options will be available to all users beginning this week.

Earlier this year, the Electronic Frontier Foundation found that the Ring’s Android app was “packed with third-party trackers sending out a plethora of customers’ personally identifiable information.” In response, Ring has announced that it will be “temporarily pausing the use of most third-party analytics services in the Ring apps and website” while it works to deliver greater control over opt-out options.

Ring offers very limited and somewhat hidden opt-out control via its website but says it will be providing “additional options to limit sharing information with third-party service providers” in early spring.
