The NSA isn't limiting itself
to telephone metadata and email communications. The agency is building a
massive database of photos as part of a facial recognition projection
to track and identify targets, reports The New York Times.
Millions of images are collected per day, according to documents
obtained by Edward Snowden, with some 55,000 of "facial recognition
quality."
One presentation explaining the
program says "It’s not just the traditional communications we’re after:
It’s taking a full-arsenal approach that digitally exploits the clues a
target leaves behind in their regular activities on the net to compile
biographic and biometric information" to "implement precision
targeting." Images are likely harvested from social media sites such as
Facebook as well as from private communications captured by the NSA. But
the latter would require court approval if domestic communications were
targeted.
Databases of images can be used to identify and track subjects — if the facial recognition technology is advanced enough. According to the Times, presentations show how the technology could match two photos of the same man, one bearded and the other not.
