Its makers boast that it can scan 36 million faces per second.
The technology raises the spectre of governments – or other organisations – being able to ‘find’ anyone instantly simply using a passport photo or a Facebook profile.

The software automates the process of searching large numbers of faces in days of CCTV footage. It will be available in the next tax years, say its makers
