A Study on Access Control Model for Context-Aware Workflow

In this paper, we explore security considerations on context-aware workflow systems. We also present the workflow-aware context-role based access control (WCRBAC) model that is a new access control model suitable for context-aware workflow systems. The WCRBAC model enables security administrator to configure authorization policy considering both the security-related context information and the workflow-related data, as well as organization's structural information.
