Abstract

An access control model for Semantic Web should be compatible with the corresponding semantic model. The access control procedure(s) should also take the semantic relationships between the entities (specified as ontologies) into account. Considering the benefits of logic-based models and the description logic foundation of Semantic Web, in this paper, we propose an access control model based on a temporal variant of description logics (TL-ACCF). This logical schema enables us to express history constrained policies to enrich the policy-base with dynamic properties based on previous accesses. The specification of each component of the model as well as the approach to define history constrained policies along with some clarifying examples are presented. The access control procedure of the model is proposed over the inference services of TL-ALCF.
