Live facial recognition criticised as ‘Orwellian’ as Met police to continue use

Human rights groups say cameras are form of mass surveillance, as report finds ‘substantial improvement’ in accuracy

Live facial recognition cameras are a form of mass surveillance, human rights campaigners have said, as the Met police said it would press ahead with its use of the “gamechanging” technology.

Britain’s largest force said the technology could be used to catch terrorists and find missing people after research published on Wednesday reported a “substantial improvement” in its accuracy.
