Fine-Grained View-Based Access Control for RDF Cloaking

´Location cloaking´ allows services to access larger location description (for instance, ´Austria´), instead of fine grained location information (for instance, ´a restaurant in Tyrol´) to preserve privacy, while keeping any useful services (for instance, ´automatic language-translation´) continuing. This paper proposes an extension of location/spatial cloaking technique for RDF data based on view-based access control. Our system starts from a fine-grained view defining method, making use of structural characteristics of interlinked RDF data. It supports cloaking of non-hierarchical data by allowing abstract hierarchy definitions of resources and views. We implement a prototype system named ´Husk´ on top of an RDF repository system.
