Abstract: We demonstrate the first, to the best of our knowledge, LBS client that safeguards user privacy against non-trustworthy LBS servers. Our collaborative approach allows the client to obtain responses from its near-by peers rather than submitting the query to the LBS. Our demo makes the user aware of her privacy level and offers tunable user parameters. The demo contributes a novel user-centric approach that enhances privacy without altering the business model of location-based services. Introduction. Smart phone users are now offered localization devices (integrated GPS receivers) or positioning services (e.g., based on near-by infrastructure). This enables a range of location-based services (LBS), allowing users to submit queries on their points of interest (POI) when they
