Police Use of Facial Recognition Violates Human Rights, UK Court Rules (arstechnica.com) 58

Posted by BeauHD from the privacy-victory dept.
An appeals court ruled today that police use of facial recognition technology in the UK has "fundamental deficiencies" and violates several laws. Ars Technica reports: South Wales Police began using automated facial recognition technology on a trial basis in 2017, deploying a system called AFR Locate overtly at several dozen major events such as soccer matches. Police matched the scans against watchlists of known individuals to identify persons who were wanted by the police, had open warrants against them, or were in some other way persons of interest. In 2019, Cardiff resident Ed Bridges filed suit against the police, alleging that having his face scanned in 2017 and 2018 was a violation of his legal rights. Although he was backed by UK civil rights organization Liberty, Bridges lost his suit in 2019, but the Court of Appeal today overturned that ruling, finding that the South Wales Police facial recognition program was unlawful.

"Too much discretion is currently left to individual police officers," the court ruled. "It is not clear who can be placed on the watchlist, nor is it clear that there are any criteria for determining where AFR can be deployed." The police did not sufficiently investigate if the software in use exhibited race or gender bias, the court added. The South Wales Police in 2018 released data admitting that about 2,300 of nearly 2,500 matches -- roughly 92 percent -- the software made at an event in 2017 were false positives. The ruling did not completely ban the use of facial recognition tech inside the UK, but does narrow the scope of what is permissible and what law enforcement agencies have to do to be in compliance with human rights law. Other police inside the UK who deploy facial recognition technology will have to meet the standard set by today's ruling. That includes the Metropolitan Police in London, who deployed a similar type of system earlier this year.

          In any country you could drive through fairly populated areas with few cameras, the average of all those with the dense urban areas is pretty useless.

        I'm no fan of this at all, but the judgement doesn't say they can't use facial recognition - more like "you need to have some better justification, and your watchlist needs to be more accountable/transparent" (and some stuff about racial/gender bias). The Welsh police can absolutely still use FR - they just need some better procedures, and get the vendor to do due-diligence on bias.

      You know the City of London is one square mile, right?

      It's literally called that? The Square Mile.

      And most of the cameras within it are privately-owned, nothing to do with the state?

      So from this you have - like every other idiot - extrapolated that the whole country is blanketed in facial-recognition cameras all talking to the state and watching everything that everyone in the country does.

      And what does "on a daily basis" mean? It's a camera. It's operational 24/7. Whether there's even someone LOOKING at it, that's highly unlikely, especially for a privately-owned camera.

      This really is the dumbest extrapolation that I hear on a regular basis from Americans believing that the UK is something out of 1984.

      The school I work in has 64 cameras, 82 if you count our other site. That other site is a nursery. Are we sitting watching it 24/7? No. Does it have face-rec? No, we're lucky if you can see a face. Why do we have it? Primarily to put people off breaking in. Did it cost a fortune? Not really. A drop in the ocean to any premises costs. The front gate that opens on a button costs more. The printed signposts out the front cost more.

      Have we ever given the state access to the cameras? No. Have we ever used the footage from the cameras? Once or twice when we knew something had happened and just wanted the footage of how/who. Do we watch even one camera 24/7? Nope. Would we? Nope. We don't even have a "security" guy in that respect. That's why we have cameras - to deter people from trying.

      Are we "in London"? You mean that 1,569 km Greater London? (Yes) Or the 28km "Central London"? Or the 2.9 km City of London?

      And if you haven't noticed, the cameras that are police cameras, with face rec, and central storage and processing, are so good that they actually do WORSE than just picking a guy out of a crowd and seeing if he has weed on him. Copper's instinct literally trumps anything to do with the cameras, when you look at the stats. Per actual, convictable charge after arrest they cost hundreds of thousands of pounds. They're useless.

      But you keep on. Because obviously I should be living in fear of a square mile of tourist attractions, where hardly anyone can afford to actually live, that has such expensive houses and businesses that they decide themselves to put up cameras, cameras that mostly do nothing more than record to a cheap NVR box in most instances.

      Despite the fact that the 8 million people who live in London don't go anywhere near that square mile, in which only 8000 (very rich!) people live and have a lot of cameras to protect their personal property and in which the police put up cameras to watch the tube stations, pubs, main vehicular routes etc.

      I've lived in or around London my entire life, and I can't say that I've ever noticed or cared about any significant camera presence in that time. Mostly because I'm someone who's fitted hundreds of them in my life and know they are mostly there "just in case" for private individuals.

      I'm gonna guess that you've never been to London for more than a tourist visit. Ask most Londoners if they fear the cameras and they'll say "What cameras?"

It says that the police have too much power to put anyone they like on the list of faces to be recognized, and that the police didn't bother checking to see if the technology discriminates against race or gender.

        Yep. There's nothing inherently wrong with using a watch list or a list of active warrants to match against facial recognition, as long as the person is not immediately arrested (but you could have a cop approach them and make contact to confirm identity). The main issue is that you need to have approved, standardized processes/criteria for putting people on those watch lists, and they have to be followed.

    From the verdict [judiciary.uk]

    'The appeal succeeded on Ground 1, that the DC erred in concluding that SWP’s interference with Mr Bridges’s Article 8(1) rights was “in accordance with the law” for the purposes of Article 8(2). : [...] there was no clear guidance on where AFR Locate could be used and who could be put on a watchlist. The Court held that this was too broad a discretion to afford to the police officers to meet the standard required by Article 8(2).'

    'The appeal failed on Ground 2, that the DC erred in determining that SWP’s use of AFR was a proportionate interference with Article 8 rights under Article 8(2). The Court held that the DC had correctly conducted a weighing exercise [...] The benefits were potentially great, and the impact on Mr Bridges was minor, and so the use of AFR was proportionate under Article 8(2).'

    'The appeal succeeded on Ground 3, that the DC was wrong to hold that SWP provided an adequate “data protection impact assessment” (“DPIA”) as required by section 64 of the DPA 2018. The Court found that, as the DPIA was written on the basis that Article 8 was not infringed, the DPIA was deficient.'

    'The appeal failed on Ground 4, that the DC was wrong to not reach a conclusion as to whether SWP had in place an “appropriate policy document” within the meaning of section 42 DPA 2018.'

    'The appeal succeeded on Ground 5, that the DC was wrong to hold that SWP complied with the PSED. The Court held that the purpose of the PSED was to ensure that public authorities give thought to whether a policy will have a discriminatory potential impact. SWP erred by not taking reasonable steps to make enquiries about whether the AFR Locate software had bias on racial or sex grounds. The Court did note, however, that there was no clear evidence that AFR Locate software was in fact biased on the grounds of race and/or sex.'

    So the appeal was (partly) granted mostly because of procedural stuff: the police haven't done their homework; that's what Points 1, 3, 4 and 5 are about. Plaintiff lost on Point 2, the most crucial one that actually is about human rights, and whether or not facial recognition can be used by the police in general. The court states in clear terms that use of this technology is proportionate.

  • It is well-known that any technology based on cameras has difficulties to identify black people - because their faces are darker, providing less light and less contrast and making it harder to recognise someone. (I'd be curious about Apple's FaceID which works in a completely different way).
