(New York Times) The National Security Agency is harvesting huge numbers of images of people from communications that it intercepts through its global surveillance operations for use in sophisticated facial recognition programs, according to top-secret documents.

The spy agency’s reliance on facial recognition technology has grown significantly over the last four years as the agency has turned to new software to exploit the flood of images included in emails, text messages, social media, videoconferences and other communications, the N.S.A. documents reveal. Agency officials believe that technological advances could revolutionize the way that the N.S.A. finds intelligence targets around the world, the documents show. The agency’s ambitions for this highly sensitive ability and the scale of its effort have not previously been disclosed.

Police departments are acquiring major battlefield equipment that emboldens officials to strong-arm those they should be protecting. “Police State USA: How Orwell’s Nightmare is Becoming our Reality” (Autographed) chronicles how we got to this point.

The agency intercepts “millions of images per day” — including about 55,000 “facial recognition quality images” — which translate into “tremendous untapped potential,” according to 2011 documents obtained from the former agency contractor Edward J. Snowden.
