Abstract
Solving location privacy is crucial in the current environment filled with smartphones and GPS, where privacy leakage can reveal extremely sensitive data about the user. The nature of routing and geographical patterns makes location privacy distinct from regular privacy, driving us to create a new way to quantify and measure location data privacy. We then introduce a new routing protocol that ensures our privacy metric is maintained, by finding all possible routes between two regions to hide the actual route in. The amount of points in each region and the overlap between the routes help us measure the amount of privacy that is ensured. We implement and test the algorithm and real map data and routes. Finally, we evaluate our new privacy metric and protocol, showing that our privacy metric and routing algorithm are theoretically sound and functionally practical.
