Upstream programNSA slides explain the PRISM data-collection program Published: June 6, 2013, Updated July 10, 2013 The top-secret PRISM program allows the U.S. intelligence community to gain access from nine Internet companies to a wide range of digital information, including e-mails and stored data, on foreign targets operating outside the United States. The program is court-approved but does not require individual warrants. Instead, it operates under a broader authorization from federal judges who oversee the use of the Foreign Intelligence Surveillance Act (FISA). Some documents describing the program were first released by The Washington Post on June 6. The newly released documents below give additional details about how the program operates, including the levels of review and supervisory control at the NSA and FBI. The documents also show how the program interacts with the Internet companies. These slides, annotated by The Post, represent a selection from the overall document, and certain portions are redacted.
