Could someone predict where you’ll be tomorrow?
According to the Fourtrace website, “Fourtrace is a research project in “Advanced topics in Computer Networking” at University of California
, Santa Barbara. Our goal is to find out if it’s possible to predict where a user is at a given time.”
The site uses only the public Foursquare check-ins found on Twitter, so it is limited to only what Foursquare users choose to share. However, even those who limit their public sharing have the potential to display predictable patterns of behavior. Over a long enough period of time, even small amounts of sharing begin to add up. How could it the information be used? Time will tell.
