Automated Facial Recognition Surveillance

Diane Abbott Excerpts

Monday 27th January 2020 Commons Chamber

[Kit Malthouse]

In his usual pithy manner, my right hon. Friend puts his finger on the button. As Members will know, the police have used facial recognition since their establishment. There is an analogue version—a wanted poster. We will have seen those and they crowdsource the identification of wanted criminals. The only question here is whether a human being does it, such as a spotter at a football match, or a machine does it. We acknowledge that if a machine is doing it, more circumspection and democratic control are required, and that is what we will be providing.

[Ms Diane Abbott (Hackney North and Stoke Newington) (Lab)]

Facial recognition technology is potentially an important crime-fighting tool, but not without the correct safeguards, and the Minister has failed to persuade the House thus far that all the correct safeguards are in place. Does he accept that the random use of facial recognition technology requires not just a High Court judgment, but a specific legal framework and specific arrangements for scrutiny? After all, when blood, saliva or hair samples are provided, they are done voluntarily or under compulsory detention and charge. Facial recognition evidence is given involuntarily. He will have heard different reports about the unreliability of the evidence. Does that put people at risk of being wrongly accused of a crime? He will have heard the reports that the facial recognition technology finds it difficult to recognise black people and women, and that the technology deployed is often inaccurate. To bring in technology that might be inaccurate and mean that the guilty go unapprehended and the innocent are wrongly identified would be a spectacular own goal, leading to a breakdown of the bond of trust between the police and public.

[Kit Malthouse]

The right hon. Lady is right to say that the police must deploy technology so as to increase the trust of those they seek to protect, rather than to diminish it. We certainly believe that the use of this technology could, as she said, have enormous potential for crimefighting, if deployed in the correct way. She asked whether the random use of facial technology could undermine that confidence. It might, but of course we are not intending to use it in a random way and the police are not doing so. In effect, they will be operating it in a very specific intelligence-led way, with lots of notification in the area in which it is to be deployed against a known list of wanted suspects or criminals; a specific area will be identified where the police have intelligence that that person might be passing through. Those very specific and focused arrangements will be authorised by a very senior officer above commander rank.

As for unreliability, as technology is rolled out it obviously becomes more and more effective and reliable—[Interruption.] Well, I am the lucky owner of a telephone that allows me to make banking payments on the basis of recognising my face. That technology was not available in the last iteration of the phone—it is an iPhone—which used my thumb instead. So there are developments in technology. South Wales police found in trials that there was a 1:4,500 chance of triggering a false alert and more than an 80% chance of a correct alert. It is worth bearing in mind that even when the system does alert the police to a possible identification, the final decision as to whether to intervene with an individual is still taken by a human being.
