(ECNS) — A top-secret $2 billion facility in Salt Lake City, known as the Utah Data Center of the National Security Agency (NSA), is a storehouse for incredible amounts of both public and private data from international and domestic citizens, the US-based Sing Tao Daily reported on Monday.

The newly built spy complex is said to be filled with main servers of the PRISM program (a clandestine national security electronic surveillance program operated by NSA since 2007), housing all digital data, including video chats, Google search history, Facebook announcements, file transfers, as well as intercepted emails and cellphone calls, on an ongoing daily basis.

William Binney, a former NSA employee and senior crypto-mathematician analyst, estimates that the servers in the new facility are capable of storing digital data of the entire mankind in the upcoming century.

With this program, NSA is able to reach directly into the servers of the participating companies and obtain both stored communications as well as perform real-time collections on targeted users.

Former CIA Director David Petraeus once presented details on the "big data" spy grid and urged his colleagues working in intelligence to learn to "swim" in the sea of "big data".
