A Middleware Architecture for Integrating Privacy Preferences and Location Accuracy

Abstract

Location-Based Access Control (LBAC) systems support the evaluation of conditions on locations in the enforcement of access control policies. The ability to evaluate conditions on a set of authorized locations has a number of well-known advantages, including enriching access control expressiveness. However, when locations are used in combination with personal identities, users privacy must be considered. In this paper, we describe a solution to integrate a LBAC system with privacy-enhanced techniques based on location obfuscation. Our solution is based on a privacy-aware middleware component that explicitly addresses the trade-off between users privacy and location accuracy by satisfying preferences set by users and maximizing the quality of location information released to LBAC systems.KeywordsLocation AccuracyLocation PrivacyLocation ProviderAccess Control PolicyUser PrivacyThese keywords were added by machine and not by the authors.
