Concept Alignment in Attribute Based Access Control
Concept alignment, namely how to make different domains know each other about the semantics of concepts defined by them, is one of the key issues of applying attribute based access control in dynamic open multi-domain environment. In this paper, a novel approach is proposed for building up a concept alignment framework based on other domains’ knowledge about specific concept relationship. The knowledge comprises five different definite concept relationships which are represented by five logical formulae respectively. Compared with the numerical similarity and those related approaches, the knowledge is more suitable for depicting concept relationship, while the proposed approach is more adapted in access control. Finally, a trust degree model is introduced into the framework in order to improve the quality of concept alignment results, and how to use and manage the trust degree is discussed.
