Location Privacy Using User Anonymity and Dummy Locations

This paper concentrates on location privacy, a particular type of information privacy that can be defined as the ability to prevent others from learning one’s current or past location. Here we are proposing a new technique that uses user anonymity and dummy locations for location privacy while using location aware application server. User communicates with the server through a trusted proxy server. It sends dummy locations to the application server with its original position. The user uses temporary pseudonyms that are changed frequently according to some algorithm. Whenever pseudonyms are changed by a user, dummy locations are chosen in a tricky fashion. That makes the task of tracing the user very difficult.
