Facial Recognition: Police Use

Siân Berry Excerpts

I thank every Member here for coming to this debate and I thank the right hon. Member for Maldon (Sir John Whittingdale) for securing it in the first place.

I have worked on this issue for many years. In my previous job, I attended and observed the first deployments of live facial recognition by the Metropolitan police, which is many years ago now. Since then, the gap between its increasing use and the lack of a legislative basis has grown wider and wider. In that time, many thousands of people have had their personal data captured and used by the police when there was absolutely no reason for that. Many people have been misidentified, but the accuracy issue is not my main concern.

The unlegislated use of the technology is incredibly worrying. In my previous job on the London Assembly, I asked the Met and the Mayor of London many questions about that. I asked for watchlist transparency, but I did not get it. I heard the initial promises—“Oh, it will be very transparently used, we will communicate it, and no one will have to walk past it without knowing.” All those reassurances just faded away, because there is no real scrutiny or legislation. We need to debate the subject from first principles. As other Members have pointed out, we have had proper debates about identity cards and fingerprint and DNA data, but not about this extremely intrusive technology. It is more concerning than other technologies because it can be used on us without our knowledge. It really does engage our human rights in profound ways.

For all those reasons, the use of facial recognition by the police has been challenged by the Information Commissioner, the Surveillance Camera Commissioner, the Biometrics Commissioner, London Assembly members, of whom I was one, Senedd Members and Members of Parliament here. The only detailed scrutiny of the technology has resulted in calls for a halt to its use; I am thinking of the Science, Innovation and Technology Committee. The Justice and Home Affairs Committee has also called for primary legislation. That is the absolutely key question. The EU has had the debate and looked at the issue in detail, with the result that over there what is used so much by the UK police is restricted to only the most serious cases of genuine public safety. That absolutely needs to happen here.

The legislation needs to look not just at police use of the technology, but private use. I have seen its use by private companies in the privately owned public space in King’s Cross. Data from there has been shared with the police; the police initially denied knowing anything about it and then later apologised for that denial. If private companies are collecting data and sharing it with the police, that needs to be scrutinised. If private companies are using the technology, that needs to be legislated for as well.

The hon. Lady is making an incredibly powerful speech. Is she aware of the Big Brother Watch campaign to try to stop large shops from capturing people’s faces and saying that they are shoplifters? They then get stopped in other places, but they are not aware of that process.

[Siân Berry]

Yes, I am aware of Big Brother Watch’s excellent campaigning on this issue. It has identified a serious breach of human rights. There is the potential for a serious injustice if people are denied access to their local shops based on a suspicion that has put them on a watchlist that may or may not be accurate. There is no oversight. We need to debate these things and legislate for them.

I tabled a written question to the Minister about putting regulation and legislation behind the police use of live facial recognition. The answer stated that the technology is governed by data protection and equality and human rights legislation, and supplemented by specific police guidance. I do not believe that police guidance is sufficient, given the enormous risks to human rights. We need a debate on primary legislation. I hope that the Minister will announce that that process will start soon and that this unlawful grey area will not be invading our privacy for much longer. This issue is urgent.
