ECHELON is a massive system designed to intercept virtually all email and fax traffic in the world and subject it to automated analysis, despite laws in many nations (including this one) barring such activity. The laws were circumvented by a mutual pact among five nations. It is illegal for the United Kingdom to spy on its citizens. Likewise the same for the United States. Under the terms of the UKUSA agreement, Britain spies on Americans and America spies on British citizens and the two groups trade data. Technically, it may be legal, but the intent to evade the spirit of the laws protecting the citizens of those two nations is clear.

ECHELON has been in development since 1947, the result of the BRUSA and UKUSA treaties signed by the governments of the United States, the United Kingdom, Canada, Australia and New Zealand.

Designed and co-ordinated by United States National Security Agency (NSA), the ECHELON system is used to intercept ordinary e-mail, fax, telex, and telephone communications carried over the world's telecommunications networks. Unlike many of the electronic spy systems developed during the Cold War, ECHELON is designed primarily for non-military targets: governments, organisations, businesses, and individuals in virtually every country. It potentially affects every person communicating between (and sometimes within) countries anywhere in the world.

ECHELON is not designed to eavesdrop on a particular individual's e-mail or fax link. Rather, the system works by indiscriminately intercepting very large quantities of communications and using computers to identify and extract messages of interest from the mass of unwanted ones. A chain of secret interception facilities has been established around the world to tap into all the major components of the international telecommunications networks. Some monitor communications satellites, others land-based communications networks, and others radio communications. ECHELON links together all these facilities, providing the United States and its allies with the ability to intercept a large proportion of the communications on the planet.

The computers at each station in the ECHELON network automatically search through the millions of messages intercepted for ones containing pre-programmed keywords. Keywords include all the names, localities, subjects, and so on that might be mentioned. Every word of every message intercepted at each station gets automatically searched whether or not a specific telephone number or e-mail address is on the list.

The five intelligence agencies that constitute the UKUSA agreement are the National Security Agency (or NSA, from the USA), the Government Communications Headquarters (GCHQ - United Kingdom), the Government Communications Security Bureau (GCSB - New Zealand), the Communications Security Establishment (CSE from Canada), and the Defence Signals Directorate (DSD in Australia). This alliance, which grew from co-operative efforts during World War II to intercept radio transmissions, was formalised into a written agreement in 1948 and aimed primarily against USSR. The agencies are today the largest intelligence organisations in their respective countries. With much of the world's business occurring by fax, e-mail, and phone, spying on these communications receives the bulk of intelligence resources. For decades before the introduction of the ECHELON system, the UKUSA allies did intelligence collection operations for each other, but each agency usually processed and analysed the intercept from its own stations.

Those computers in spy stations are known as the Echelon dictionaries. However, computers that can automatically search through traffic for keywords have existed since at least the 1970s, but the ECHELON system was designed by NSA to interconnect all these computers and allow the stations to function as components of an integrated whole.

The only public reference to the Dictionary system anywhere in the world was in relation to one of these facilities, run by the GCHQ in central London. In 1991, a former British GCHQ official spoke anonymously to Granada Television's World in Action about the agency's abuses of power. He told the program about an anonymous red brick building at 8 Palmer Street where GCHQ secretly intercepts every telex which passes into, out of, or through London, feeding them into powerful computers with a program known as "Dictionary."

The journalist Nick Hager discovered thanks to several interviews with more than 50 people concerned with New Zealand’s Signal Intelligence Agency, that there is a network of spy stations around the globe. Inside it, "the thousands of simultaneous messages are read in real time as they pour into each station, hour after hour, day after day, as the computers find intelligence needles in telecommunications haystacks".

Similarly, British researcher Duncan Campbell has described how the US Menwith Hill station, near Harrogate, in North Yorkshire (Great Britain) taps directly into the British Telecom microwave network, which has actually been designed with several major microwave links converging on an isolated tower connected underground into the station.

Menwith Hill Station was established in 1956 by the US Army Security Agency (ASA). Inside the closely-guarded 560 acre base are two large operations blocks and many satellite tracking dishes and domes. Initial operations focused on monitoring international cable and microwave communications passing through Britain. In the early 1960s Menwith Hill was one of the first sites in the world to receive sophisticated early IBM computers, with which NSA automated the labour-intensive watch-list scrutiny of intercepted but unenciphered telex messages. Since then, Menwith Hill has sifted the international messages, telegrams, and telephone calls of citizens, corporations or governments to select information of political, military or economic value to the United States.

Every detail of Menwith Hill's operations has been kept an absolute secret. The official cover story is that the all-civilian base is a Department of Defence communications station. The British Ministry of Defence describe Menwith Hill as a "communications relay centre." Like all good cover stories, this has a strong element of truth to it. Until 1974, Menwith Hill's Sigint specially was evidently the interception of International Leased Carrier signals, the communications links run by civil agencies -- the Post, Telegraph and Telephone ministries of eastern and western European countries. The National Security Agency took over Menwith Hill in 1966. Interception of satellite communications began at Menwith Hill as early as 1974, when the first of more than eight large satellite communications dishes were installed.

All telecommunications traffic to and from Europe and passing through Britain is intercepted at the base, including private telephone calls, faxes, emails and other communications. Much of the information is collected, processed and relayed back to the United States automatically. A great deal of this information comes from spy satellites and the base has a number of large white golf balls or kevlar "radomes" containing satellite receiving dishes.
