Real-Time Surveillance Will Test the British Tolerance for Cameras

But now a new generation of cameras is beginning to be used. Like the one perched on the top of the Cardiff police van, these cameras feed into facial recognition software, enabling real-time identity checks -- raising new concerns among public officials, civil society groups and citizens. Some members of Parliament have called for a moratorium on the use of facial recognition software. The mayor of London, Sadiq Khan, said there was "serious and widespread concern" about the technology. Britain's top privacy regulator, Elizabeth Denham, is investigating its use by the police and private businesses.
