XKeyscore

XKeyscore is a signals intelligence software system used by the National Security Agency to search and analyze internet data, as revealed by Edward Snowden in The Guardian and The Washington Post. The system is designed to analyze metadata and content of email, chat, and browser history, allowing intelligence agencies like the Federal Bureau of Investigation and Central Intelligence Agency to track terrorist activities and cyber threats. XKeyscore is part of a larger surveillance program, which includes PRISM and Tempora, and has been used in conjunction with GCHQ and Australian Signals Directorate to monitor global communications. The system has been compared to ECHELON and Carnivore, and has raised concerns among privacy advocates like American Civil Liberties Union and Electronic Frontier Foundation.
