Global mass surveillance can be defined as the mass surveillance of entire populations across national borders. Its existence was not widely acknowledged by governments and the mainstream media until the global surveillance disclosures by Edward Snowden triggered a debate about the right to privacy in the Digital Age. One such debate is the balance which governments must acknowledge between the pursuit of national security and counter-terrorism over a right to privacy. Although, to quote H. Akın Ünver, "Even when conducted for national security and counterterrorism purposes, the scale and detail of mass citizen data collected, leads to rightfully pessimistic observations about individual freedoms and privacy". Its roots can be traced back to the middle of the 20th century when the UKUSA Agreement was jointly enacted by the United Kingdom and the United States, which later expanded to Canada, Australia, and New Zealand to create the present Five Eyes alliance. The alliance developed cooperation arrangements with several "third-party" nations. Eventually, this resulted in the establishment of a global surveillance network, code-named "ECHELON" (1971).
Historical background
The origins of global surveillance can be traced back to the late 1940s after the UKUSA Agreement was collaboratively enacted by the United Kingdom and the United States, which eventually culminated in the creation of the global surveillance network code-named "ECHELON" in 1971. In the aftermath of the 1970s Watergate affair and a subsequent congressional inquiry led by Sen. Frank Church, it was revealed that the NSA, in collaboration with Britain's GCHQ, had routinely intercepted the international communications of prominent anti-Vietnam War leaders such as Jane Fonda and Dr. Benjamin Spock. Decades later, a multi-year investigation by the European Parliament highlighted the NSA's role in economic espionage in a report entitled 'Development of Surveillance Technology and Risk of Abuse of Economic Information', in 1999. However, for the general public, it was a series of detailed disclosures of internal NSA documents in June 2013 that first revealed the massive extent of the NSA's spying, both foreign and domestic. Most of these were leaked by an ex-contractor, Edward Snowden. Even so, a number of these older global surveillance programs such as PRISM, XKeyscore, and Tempora were referenced in the 2013 release of thousands of documents. Many countries around the world, including Western Allies and member states of NATO, have been targeted by the "Five Eyes" strategic alliance of Australia, Canada, New Zealand, the UK, and the United States—five English-speaking Western countries aiming to achieve Total Information Awareness by mastering the Internet with analytical tools such as the Boundless Informant. As confirmed by the NSA's director Keith B. Alexander on 26 September 2013, the NSA collects and stores all phone records of all American citizens. Much of the data is kept in large storage facilities such as the Utah Data Center, a US $1.5 billion megaproject referred to by The Wall Street Journal as a "symbol of the spy agency's surveillance prowess."
Today, this global surveillance system continues to grow. It now collects so much digital detritus – e-mails, calls, text messages, cellphone location data and a catalog of computer viruses - that the N.S.A. is building a 1-million-square-foot facility in the Utah desert to store and process it. On 6 June 2013, Britain's The Guardian newspaper began publishing a series of revelations by an as yet unknown American whistleblower, revealed several days later to be ex-CIA and ex-NSA-contracted systems analyst Edward Snowden. Snowden gave a cache of documents to two journalists, Glenn Greenwald and Laura Poitras. Greenwald later estimated that the cache contains 15,000–20,000 documents, some very large and detailed, and some very small. In over two subsequent months of publications, it became clear that the NSA had operated a complex web of spying programs that allowed it to intercept Internet and telephone conversations from over a billion users from dozens of countries around the world. Specific revelations were made about China, the European Union, Latin America, Iran and Pakistan, and Australia and New Zealand, however, the published documentation reveals that many of the programs indiscriminately collected bulk information directly from central servers and Internet backbones, which almost invariably carry and reroute information from distant countries. Due to this central server and backbone monitoring, many of the programs overlapped and interrelated with one another. These programs were often carried out with the assistance of US entities such as the United States Department of Justice and the FBI, were sanctioned by US laws such as the FISA Amendments Act, and the necessary court orders for them were signed by the secret Foreign Intelligence Surveillance Court. Some of the NSA's programs were directly aided by national and foreign intelligence agencies, Britain's GCHQ and Australia's ASD, as well as by large private telecommunications and Internet corporations, such as Verizon, Telstra, Google, and Facebook. Snowden's disclosures of the NSA's surveillance activities are a continuation of news leaks which have been ongoing since the early 2000s. One year after the September 11, 2001, attacks, former U.S. intelligence official William Binney was publicly critical of the NSA for spying on U.S. citizens. Further disclosures followed. On 16 December 2005, The New York Times published a report under the headline "Bush Lets U.S. Spy on Callers Without Courts." In 2006, further evidence of the NSA's domestic surveillance of U.S. citizens was provided by USA Today. The newspaper released a report on 11 May 2006, regarding the NSA's "massive database" of phone records collected from "tens of millions" of U.S. citizens. According to USA Today, these phone records were provided by several telecom companies such as AT&T, Verizon, and BellSouth. In 2008, the security analyst Babak Pasdar revealed the existence of the so-called "Quantico circuit" that he and his team discovered in 2003 when brought on to update the carrier's security system. The circuit provided the U.S. federal government with a backdoor into the network of an unnamed wireless provider, which was later independently identified as Verizon.

![Global surveillance: The New York Times, citing documents leaked by Snowden, reported in September 2013 on the NSA's "push to exploit phone and e-mail data of Americans after it lifted restrictions in 2010", which enables "large-scale graph analysis on very large sets of communications metadata".[43] This slide from an NSA presentation shows one of the methods in which the agency uses e-mail and phone data to analyze the relationship network of a target. According to The Times, the NSA can "augment the communications data with material from public, commercial and other sources, including bank codes, insurance information, Facebook profiles, passenger manifests, voter registration rolls and GPS location information, as well as property records and unspecified tax data".[44] Such types of data were collected from U.S. citizens as well as foreign nationals.[44]](https://upload.wikimedia.org/wikipedia/commons/thumb/c/cc/NSA_Syanpse_Data_Model.png/500px-NSA_Syanpse_Data_Model.png?utm_source=en.wikipedia.org&utm_campaign=parser&utm_content=thumbnail)
