Dear All,<br><br>We integrated Tor with a location based service to implement a location privacy preserving location based service. <br>1. Tor is used to hide the identity (IP) of a user, who sends her location to a location based service server for points of interest. Hiding IP is also necessary for hiding the user location since IP may imply the user's location. <br>
2. Of course, the user's location coordinates are also perturbed to hide her exact location.<br><br>Here is the link of the software: <a href="http://www.seas.gwu.edu/~nzhang10/cap/cap/Welcome.html">http://www.seas.gwu.edu/~nzhang10/cap/cap/Welcome.html</a>.
