The NSA isn't just interested in pure communications intelligence like call
records; it wants to look for faces, too. Documents leaked by Edward Snowden
reveal that the NSA has been using facial recognition software to scan the
internet for portraits and match them with investigative data. The agency
can determine whether or not a suspect spotted in a photo or video chat has
a valid passport, for example, or find out if informants have said anything
about that person. It can even spot subtle changes (like beards) and link
photos to satellite info to pinpoint someone's whereabouts. As of 2011, the
NSA was getting about 55,000 "facial recognition quality" images per day out
of "millions" of candidates, according to the leaked material. |
