Guardian.co.uk: Boundless informant: the NSA’s secret tool to track global surveillance data / Revealed: The NSA’s powerful tool for cataloguing global surveillance data – including figures on US by Glenn Greenwald and Ewan Mackaskill:

The National Security Agency has developed a powerful tool for recording and analysing where its intelligence comes from, raising questions about its repeated assurances to Congress that it cannot keep track of all the surveillance it performs on American communications.

The Guardian has acquired top-secret documents about the NSA datamining tool, called Boundless Informant, that details and even maps by country the voluminous amount of information it collects from computer and telephone networks.

The focus of the internal NSA tool is on counting and categorizing the records of communications, known as metadata, rather than the content of an email or instant message.
