Police: Biometrics
The question
To ask the Secretary of State for the Home Department, what assessment she has made of the cost-effectiveness of police use of live facial recognition technology in comparison to traditional policing methods.
Answered by Sarah Jones
The Home Office has not made a final assessment of the cost‑effectiveness of police use of live facial recognition (LFR) technology in comparison to traditional policing methods. However, when the government introduces legislation on a new framework this will be accompanied by an impact assessment. This will include consideration of costs, operational benefits and wider impacts, alongside legal, ethical and equality considerations.
With regards to the integration of facial recognition into existing CCTV, police forces must comply with data protection, human rights, equality and other relevant laws. This means that police can use live facial recognition only for targeted, intelligence led, time-bound deployments to locate specific individuals on a watchlist, such as wanted offenders or people who may pose a risk of serious harm.
The Home Office is aware that both the Metropolitan Police and South Wales Police have piloted the use of facial recognition cameras mounted on fixed street infrastructure. This involves adding standalone LFR cameras and does not involve changing the use of existing CCTV, which remains separate.
