W-RBAC - A workflow security model incorporating controlled overriding of constraints
International Journal Of Cooperative Information Systems. World Scientific Publ Co Pte Ltd, v. 12, n. 4, n. 455, n. 485, 2003.
This paper presents a pair of role-based access control models for workflow systems, collectively known as the W-RBAC models. The first of these models, W0-RBAC is based on a framework that couples a powerful RBAC-based permission service and a workflow component with clear separation of concerns for ease of administration of authorizations. The permission service is the focus of the work, providing an expressive logic-based language for the selection of users authorized to perform workflow tasks, with preference ranking. W1-RBAC extends the basic model by incorporating exception handling capabilities through controlled and systematic overriding of constraints.124455485
