NSA uses social media to map connections of Americans
2 Oct 2013 12:07 AM IST
The National Security Agency mines Facebook and other social media profiles, in addition to phone records and email logs, to create maps of activities, including that of American citizens. Since 2010, NSA has been exploiting its huge collections of data to create sophisticated graphs of some Americans’ social connections that can identify their associates, their locations at certain times, their travelling companions and other personal information, New York Times reported.
The paper, quoting documents provided to it by former NSA contractor Edward Snowden, said the NSA can augment the communications data with material from public, commercial and other sources, including bank codes, insurance information, Facebook profiles, passenger manifests, voter registration rolls and GPS location information, as well as property records and unspecified tax data.
They do not indicate any restrictions on the use of such ‘enrichment’ data and several former senior Obama administration officials said the agency drew on it for both Americans and foreigners.
‘We assume as Americans that if somebody in the government is looking at your information, it’s because they have a reason, because you’re suspected of a crime,’ said Karen Greenberg, director of the Center on National Security at Fordham Law School. The documents do not specify how many Americans’ social connections were analysed, or whether any have been implicated in wrongdoing.
The surveillance began after a policy change in November 2010. Prior to then, the ‘chaining’ of a foreign person’s contacts had to stop when it reached an American citizen or legal resident. The policy change was intended to help NSA ‘discover and track’ connections from a foreign intelligence subject to an American citizen, according to the leaked documents.
Defending the practice, president Barack Obama has ordered a review of NSA’s data collection practices because of Snowden’s leaks. But the president has defended the use of such methods to gather intelligence on terrorists and other threats.
