Software that tracks people on social media created by defence firm

A multinational security firm has secretly developed software, called Riot, capable of tracking people’s movements and predicting future behavior by mining data from social networking websites.

Raytheon, the world’s fifth largest defence contractor, has acknowledged the technology was shared with US government and industry as part of a joint research and development effort, in 2010, to help build a national security system capable of analysing “trillions of entities” from cyberspace.
