Abstract
Workflow systems are often associated with business process re‐engineering (BPR). This paper argues that the functional access control requirements in workflow systems are rooted in the scope of a BPR project. A framework for access control in workflow systems is developed. The framework suggests that existing role‐based access control mechanisms can be used as a foundation in workflow systems. The framework separates the administration‐time and the run‐time aspects. Key areas that must be investigated to meet the functional requirements imposed by workflow systems on access control services are identified.
