A multinational security firm has secretly developed software capable of tracking people's movements and predicting future behaviour by mining data from social networking websites. <br />A video obtained by the Guardian reveals how an "extreme-scale analytics" system created by Raytheon, the world's fifth largest defence contractor, can gather vast amounts of information about people from websites including Facebook, Twitter and Foursquare. <br />Raytheon says it has not sold the software – named Riot, or Rapid Information Overlay Technology – to any clients. <br />But the Massachusetts-based company 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.
