NSA uses metadata “to create sophisticated graphs” of US citizens’€™ social connections

The US National Security Agency has been exploiting US citizens’ personal information drawn from its large collection of metadata to create complex graphs of social connections for foreign intelligence purposes, the latest Snowden leaks have revealed. Documents obtained by the New York Times from the former NSA contractor Edward Snowden say that the practice has been going on since November 2010, after restrictions prohibiting the agency from working with US citizens’ data were “lifted” by NSA officials.
