If you have attracted the "wrong kind" of attention by the government, then the intrusive data-mining analytic software developed by defense contractor Raytheon may be able to figure out your next move before you make it.
Wikipedia explained the "extreme-scale analytics" systems that Raytheon calls Rapid Information Overlay Technology (RIOT). It "allows the user to track people's movements and even predict their behavior by mining data from social networking sites including Facebook, Twitter, Gowalla, and Foursquare. Raytheon claims that it has not sold this software to any clients, but has shared it with US government and industry."
The software is not "new," but the video obtained by the Guardian is new to us, the public. In it, Raytheon's 'principal investigator' Brian Urch explained how RIOT software works. He used a Raytheon employee dubbed "Nick" before showing how to use the software to find pictures of Nick as well as where he checks in or has otherwise given away his location. Some of the most disturbing quotes include, "Now we know where Nick's going; we know what he looks like and now we're going to try to predict where he may be in the future." The results showed the top ten places where he has checked in.
