CCTV cameras are a daily reality of life in UK cities, but advances in facial recognition technology are moving police surveillance into a new phase. The Metropolitan police recently announced the introduction of live facial recognition technology, which will be limited to specific locations in London. Now a leaked Home Office paper suggests 10 other forces are also trialling this technology.

Police commissioners believe this could revolutionise the fight against crime, and after another terrorist attack this week public pressure for improved surveillance is likely to increase. However, campaigners warn that we could be ushering in the kind of society George Orwell envisaged in his dark novel Nineteen Eighty-Four.

The Guardian’s UK technology editor, Alex Hern, looks back at the origins of automated facial recognition and the ethical questions that have arisen as it has developed.
