PRISM is a clandestine[1] surveillance program under which the United States National Security Agency (NSA) collects internet communications from at least nine major US internet companies.[2][3][4] Since 2001 the United States government has increased its scope for such surveillance, and so this program was launched in 2007.
PRISM is a government code name for a data-collection effort known officially by theSIGAD US-984XN.[5][6] The PRISM program collects stored internet communications based on demands made to internet companies such as Google Inc. under Section 702 of the FISA Amendments Act of 2008 to turn over any data that match court-approved search terms.[7] The NSA can use these PRISM requests to target communications that were encrypted when they traveled across the internet backbone, to focus on stored data that telecommunication filtering systems discarded earlier,[8][9] and to get data that is easier to handle, among other things.[10]
PRISM began in 2007 in the wake of the passage of the Protect America Act under the Bush Administration.[11][12] The program is operated under the supervision of theU.S. Foreign Intelligence Surveillance Court (FISA Court, or FISC) pursuant to the Foreign Intelligence Surveillance Act (FISA).[13] Its existence was leaked six years later by NSA contractor Edward Snowden, who warned that the extent of mass data collection was far greater than the public knew and included what he characterized as "dangerous" and "criminal" activities.[14] The disclosures were published by The Guardian and The Washington Post on June 6, 2013. Subsequent documents have demonstrated a financial arrangement between NSA's Special Source Operations division (SSO) and PRISM partners in the millions of dollars.[15]
Documents indicate that PRISM is "the number one source of raw intelligence used for NSA analytic reports", and it accounts for 91% of the NSA's internet traffic acquired under FISA section 702 authority."
