Privacy-Aware Mobile Location-Based Systems
Privacy in location-based systems is a major concern, since many mobile phones have a GPS sensor that can report location within 10 meters of accuracy. The contributions of this paper are in three folds. First, we examine privacy issues in snapshot queries, and present our work and results in this area. The proposed method can guarantee that all queries are protected, while previously proposed ...
متن کاملProviding Location-Aware Location Privacy Protection for Mobile Location-Based Services
Location privacy has been a serious concern for mobile users who use location-based services provided by third-party providers via mobile networks. Recently, there have been tremendous efforts on developing new anonymity or obfuscation techniques to protect location privacy of mobile users. Though effective in certain scenarios, these existing techniques usually assume that a user has a constan...
متن کاملTowards Orientation-Aware Location Based Mobile Services
Within this paper we present an approach on how orientation sensors built into mobile devices can enable a new paradigm for mobile service discovery and use: In conjunction with 3D models of urban terrain, mobile devices can act as virtual pointers to services and information anchored at geographic locations such as buildings or landmarks. We outline a system architecture that enables this new ...
متن کاملSpecial issue on context-aware and mobile multimedia databases and services
It is expected in the near future that the number of created digital multimedia content will rise dramatically. Multimedia metadata is currently the only way to cope with problems like semantic-based information retrieval or organization of content, and provides means to specify adaptation and delivery constraints and rules. In parallel, the integration of accurate hand-held positioning within ...
متن کاملQuality Aware Privacy Protection for Location-Based Services
Protection of users’ privacy has been a central issue for location-based services (LBSs). In this paper, we classify two kinds of privacy protection requirements in LBS: location anonymity and identifier anonymity. While the location cloaking technique under the k-anonymity model can provide a good protection of users’ privacy, it reduces the resolution of location information and, hence, may d...
