Abstract
As more private data is entering the web, defining authorization about its access is crucial for privacy protection. This paper
proposes a policy language that leverages SPARQL expressiveness and
popularity for flexible access control management and enforces the protection using temporal graphs. The temporal graphs are created during
the authentication phase and are cached for further usage. They enable
design-time policy testing and debugging, which is necessary for correctness guarantee.
The security never comes with convenience, and this paper examines
the environments in which the temporal graphs are suitable. Based on
the evaluation results, an approximated function is defined for suitability
determination based on the expected temporal graph size.
