Facial Recognition Technology

Lord Anderson of Ipswich Excerpts

Wednesday 2nd October 2019 Lords Chamber

[Baroness Williams of Trafford]

I hate to differ on this with my noble friend, but e-gate technology is in fact superb at matching facial recognition to passports—in some cases, better than humans. However, the human eye in these things is of course not to be dismissed and it can detect all sorts of other things in terms of e-gates.

[Lord Anderson of Ipswich (CB)]

My Lords, the Surveillance Camera Commissioner reported in July that not only facial recognition but gait analysis, lip-reading technology, algorithms that can predict fights and sensors that can detect explosives and radiation are all in development and all linked to surveillance cameras. Given the enormous potential of those developments, both positive and negative, and the need for trust on the part of the public, will the Government commission an independent review, with clear parameters, into how, if at all, such investigatory powers should be used and how that use should be supervised in the public interest? Does she agree with the commissioner that there is a case for placing the oversight of all these powers with the existing Investigatory Powers Commissioner’s Office?

[Baroness Williams of Trafford]

I agree with the noble Lord that the emergence of these new technologies necessitates a very careful approach. The live facial recognition technology is currently being trialled rather than fully rolled out, so we need to be very careful about it. In terms of oversight, the Surveillance Camera Commissioner has provided guidance for the police. We have established an oversight board, and the police are bringing forward proposals for new trials. We are working with the police on the development of national operational guidance, which will capture the lessons learned, as well as best practice. However, the noble Lord is absolutely right: with all these new technologies, we need to tread with extreme care and balance their proportionate use with the interests of the public.
