Abstract

Today, many organizations generate large amount of data and have many users that need only partial access to resources at any time to collaborate in making critical decisions. Thus, there is a need for a scalable access control model that simplifies the management of security policies and handles the heterogeneity inherent in the information system. This paper proposes an ontology-based distributed solution to this problem, with the benefits of being scalable and producing acceptable response times.
