Abstract
Mobile devices equipped with indoor positioning capabilities can access a broad range of di erent Location-Based Services (LBS). There are advanced LBS applications that use the user's location and preferences in order to give the most precise answer to location-dependent queries. To protect privacy, the user's location and preferences must not be disclosed. Existing solutions utilize a trusted anonymizer between the users and the LBS. This approach has the drawback that this component may not always be available, and it may itself present security problems. We propose a novel framework to support private location-dependent queries, based on the concept of k-anonymity to protect the user's identity, which does not require a trusted third-party, since privacy is achieved via grid-maps and entropy-based techniques.
