A Quantitative Evaluation of Privacy in Location Based Services

Location based services like finding nearest restaurants or finding friends have increasingly became more common, especially to mobile users. Nevertheless, misuse of location information could represent some threats to users' privacy. Great effort has been placed to propose new techniques which try to deal with these threats, but in most of these cases, techniques were not tested in real environments. In this work we implemented some techniques and tested in a mobile environment. We conclude that the implementation of privacy techniques in this environment is feasible and presented acceptable response time.
