XKEYSCORE is a formerly secret computer system used by the NSA for searching and analyzing Internet data about foreign nationals across the world. The program is run jointly with other agencies including Australia's DSD, and New Zealand's GCSB. XKEYSCORE is an NSA data-retrieval system which consists of a series of user interfaces, backend databases, servers and software that selects certain types of metadata that the NSA has already collected using other methods.
