Met begins operational use of Live Facial Recognition (LFR) technology

30 January 2020

The Metropolitan Police Service has announced that it will begin the operational use of Live Facial Recognition (LFR) technology.

The use of live facial recognition technology will be intelligence-led and deployed to specific locations in London. This will help tackle serious crime, including serious violence, gun and knife crime, child sexual exploitation and help protect the vulnerable.

The technology, from NEC, is said to provide police officers with an additional tool to assist them in doing what officers have always done – to try to locate and arrest wanted people. 

The Met announced on Friday 24 January that "This is not a case of technology taking over from traditional policing; this is a system which simply gives police officers a ‘prompt’, suggesting 'that person over there may be the person you’re looking for', it is always the decision of an officer whether or not to engage with someone". 

Assistant commissioner Nick Ephgrave said: “As a modern police force, I believe that we have a duty to use new technologies to keep people safe in London. Independent research has shown that the public support us in this regard. Prior to deployment we will be engaging with our partners and communities at a local level.

“We are using a tried-and-tested technology, and have taken a considered and transparent approach in order to arrive at this point. Similar technology is already widely used across the UK, in the private sector. Ours has been trialled by our technology teams for use in an operational policing environment.

“Every day, our police officers are briefed about suspects they should look out for; LFR improves the effectiveness of this tactic.

“Similarly if it can help locate missing children or vulnerable adults swiftly, and keep them from harm and exploitation, then we have a duty to deploy the technology to do this.”

The Met will begin operationally deploying LFR at locations where intelligence suggests it is most likely to locate serious offenders. Each deployment will have a bespoke ‘watch list’, made up of images of wanted individuals, predominantly those wanted for serious and violent offences. 

At a deployment, cameras will be focused on a small, targeted area to scan passers-by. The cameras will be clearly signposted and officers deployed to the operation will hand out leaflets about the activity. The technology, which is a standalone system, is not linked to any other imaging system, such as CCTV, body worn video or ANPR.

News of the Met's decision comes a week after the European Commission revealed it is considering a ban on the use of facial recognition in public areas for up to five years while regulators try to work out a way to prevent the technology from being abused.
