Question to the Home Office:

To ask the Secretary of State for the Home Department, what assessment he has made of the accuracy of facial recognition in CCTV.

Facial recognition is a fast evolving area of technology with the potential to streamline identity verification and authentication processes across Government and the private sector.

Its performance is dependent on a number of variables, from the quality of the images, environmental factors, the specific algorithm used, the thresholds or risk profile applied and many other factors. Possible matches produced by LFR systems are always checked by a human operator before deciding what, if any, action to take.
