You've never heard of XKeyscore, but it definitely knows you. The National Security Agency's top-secret program essentially makes available everything you've ever done on the Internet — browsing history, searches, content of your emails, online chats, even your metadata — all at the tap of the keyboard.
...
This latest revelation comes from XKeyscore training materials, which Snowden also provided to The Guardian. The NSA sums up the program best: XKeyscore is its "widest reaching" system for developing intelligence from the Internet.
...
The program gives analysts the ability to search through the entire database of your information without any prior authorization — no warrant, no court clearance, no signature on a dotted line. An analyst must simply complete a simple onscreen form, and seconds later, your online history is no longer private. The agency claims that XKeyscore covers "nearly everything a typical user does on the Internet."
