A newly released set of slides from the Snowden leaks reveals that the NSA is harvesting millions of facial images from the Web for use in facial recognition algorithms through a program called "Identity Intelligence." James Risen and Laura Poitras's NYT piece shows that the NSA is linking these facial images with other biometrics, identity data, and "behavioral" data including "travel, financial, behaviors, social network."

The NSA's goal -- in which it has been moderately successful -- is to match images from disparate databases, including databases of intercepted videoconferences (in February 2014, another Snowden publication revealed that NSA partner GCHQ had intercepted millions of Yahoo video chat stills), images captured by airports of fliers, and hacked national identity card databases from other countries. According to the article, the NSA is trying to hack the national ID card databases of "Pakistan, Saudi Arabia and Iran."
