Authorization and Access Control in Adaptive Workflows

Keywords : Access control, adaptive workflow, adaptive authorizations

Abstract : In recent years we have witnessed the development of adaptive workflow management systems. These systems offer an extended set of features to support both ad-hoc and evolutionary changes, while ensuring correctness of process definition and their running instances. Ad-hoc and evolutionary changes impose new access control requirements, which have been neglected by adaptive workflow research and are not met by existing models for traditional workflow management systems (WfMSs). In this paper, we extend the role-based access control model for adaptive workflows. This extension is done by defining authorizations for adaptive WfMSs and adaptive authorizations.
