ECHELON Network
The global signals intelligence network operated by the Five Eyes alliance that intercepts satellite, radio, and cable communications worldwide.
OVERVIEW
ECHELON is the name for the global surveillance network operated by the Five Eyes intelligence alliance — the United States, United Kingdom, Canada, Australia, and New Zealand. The system intercepts satellite communications, radio transmissions, cable signals, and internet traffic on a global scale. While its existence was semi-classified for decades, it was confirmed by European Parliament investigations in 2001 that found ECHELON was capable of intercepting all communications transmitted through major global hubs. The system uses keyword filtering to flag intelligence targets. ECHELON has been the subject of allegations of industrial espionage and violation of privacy rights.
