Dear All,
We integrated Tor with a location based service to implement a location privacy preserving location based service.
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.
2. Of course, the user's location coordinates are also perturbed to hide her exact location.
Here is the link of the software: http://www.seas.gwu.edu/~nzhang10/cap/cap/Welcome.html. The paper is here: http://www.seas.gwu.edu/~nzhang10/cap/cap/Welcome_files/paper.pdf.
Happy new year!
