In the 14-09-2015 ebiquity meeting, Ankur Padia will talk about his recent work aimed at providing access control for an RDF triple store.

Attribute-based Fine Grained Access Control for Triple Stores

Ankur Padia, UMBC

The maturation of semantic web standards and associated web-based data representations like schema.org have made RDF a popular model for representing graph data and semi-structured knowledge. However, most existing SPARQL endpoint supports simple access control mechanism preventing its use for many applications. To protect the data stored in RDF stores, we describe a framework to support attribute-based fine grained access control and explore its feasibility. We implemented a prototype of the system and used it to carry out an initial analysis on the relation between access control policies, query execution time, and size of the RDF dataset.
