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.
