• XKeyscore gives ‘widest-reaching’ collection of online data • NSA analysts require no prior authorization for searches • Sweeps up emails, social media activity and browsing history
XKeyscore, the documents boast, is the NSA’s “widest reaching” system developing intelligence from computer networks – what the agency calls Digital Network Intelligence (DNI). One presentation claims the program covers “nearly everything a typical user does on the internet”, including the content of emails, websites visited and searches, as well as their metadata.
Analysts can also use XKeyscore and other NSA systems to obtain ongoing “real-time” interception of an individual’s internet activity.
