Pinwale

Pinwale is the code name for an NSA collection and retrieval system for so-called "Digital Network Intelligence", including internet e-mail. It is searchable by monitored NSA analysts.

The existence of the system was first revealed by an NSA analyst who was trained in its use during 2005. However, according to Homeland Security Today, Pinwale has in it much more than email, it also contains other forms of Internet data, and other forms of digital communications as well. Its software has built-in protections against collecting from any of the Five Eyes members. Unlike its successor XKeyscore, targets for PINWALE have to be approved beforehand by the FISC.
