Before the NSA disclosures this seemed rather harmless, as Facebook data was supposedly more or less private, i.e. not readily available to the government. Turns out, now government spooks can track you anywhere, past, present and future, because Facebook and other services pass on real-time data to them:
The U.S. government can track where you are, who you’re with, what you look like, and where you’ll likely be next thanks to a tool created by defense contractor Raytheon.
The tool, called Riot, or rapid information overlay technology, looks at your Twitter, Facebook, Gowalla, and Foursquare to determine these different data points about you, according to the Guardian, which procured a video showing off Riot. It was created out of a partnership between the U.S. government and Raytheon, though the company says it has not been sold to anyone yet.
Based on your location data, Riot can create graphs that show not only where you check in, but how often, what days of the week, and what times you most frequent that place. In the video, a Raytheon employee Brian Urch used his colleague Nick as an example. He was able to see that Nick goes to the gym most often during June on Mondays at 6 a.m.
