Raytheon, a Massachusetts defense contractor, has built tracking software that pulls information from social networks, according to a video obtained by the Guardian newspaper in London. "[Raytheon] has acknowledged the technology was shared with U.S. government and industry as part of a joint research and development effort, in 2010, to help build a national security system capable of analyzing 'trillions of entities' from cyberspace." Using public data from Facebook, Twitter, Gowalla and Foursquare, the software - called RIOT, or Rapid Information Overlay Technology - apparently gathers uploaded information and forms a profile of a person's every move that was registered with one of the websites. The video obtained by the newspaper starts with a demonstration by Raytheon's "principal investigator," Brian Urch, showing how easy it is to track an employee named Nick - a real person - based on all the places he has checked in using his smartphone. "When people take pictures and post them on the Internet using their smartphones, the phone will actually embed the latitude and longitude in the header data - so we're going to take advantage of that," Urch says. "So now we know where Nick's gone ... and now we'll predict where he'll be in the future." Urch goes on to analyze - using graphs and calendars - where Nick likes to spend his personal time and make predictions about his behavior. "If you ever wanted to get a hold of his laptop, you might want to visit the gym at 6 a.m. on Monday," Urch says with alarming casualness.
