MAINWAY is a database maintained by the United States' National Security Agency (NSA) containing metadata for hundreds of billions of telephone calls made through the largest telephone carriers in the United States, including AT&T, Verizon, and T-Mobile.[1] [2]
The existence of this database and the NSA program that compiled it was unknown to the general public until USA Today broke the story on May 10, 2006.[1]
It is estimated that the database contains over 1.9 trillion call-detail records.[3] The records include detailed call information (caller, receiver, date/time of call, length of call, etc.) for use in traffic analysis[4] and social network analysis,[5] but do not include audio information or transcripts of the content of the phone calls.[4]
According to former NSA director Michael Hayden, the NSA sought to deploy MAINWAY prior to 9/11 in response to the Millennium Plot but did not do so because it did not comply with US law. Hayden wrote: "The answer from [the Justice Department] was clear: ' ... you can't do this.'"[6] As of June 2013, the database stores metadata for at least five years.[7] According to Pulitzer Prize winning journalist James Risen, MAINWAY was the most important of the four components that comprised the ThinThread program.[8]
The database's existence has prompted fierce objections. It is often viewed as an illegal warrantless search and violation of the pen register provisions of the Foreign Intelligence Surveillance Act and (in some cases) the Fourth Amendment of the United States Constitution.
The George W. Bush administration neither confirmed nor denied the existence of the domestic call record database. This contrasts with a related NSA controversy concerning warrantless surveillance of selected telephone calls; in that case they did confirm the existence of the program of debated legality. That program's code name was Stellar Wind.[9]
Similar programs exist or are planned in other countries, including Sweden (Titan traffic database)[10] and Great Britain (Interception Modernisation Programme).
The MAINWAY equivalent for Internet traffic is MARINA.[11]
