Google has been recruited by US intelligence agencies to help them better process and share information they gather about suspects.

Agencies such as the National Security Agency have bought servers on which Google-supplied search technology is used to process information gathered by networks of spies around the world.

Google is also providing the search features for a Wikipedia-style site, called Intellipedia, on which agents post information about their targets that can be accessed and appended by colleagues, according to the San Francisco Chronicle.
