Abstract-With ubiquitous computing technologies, business processes become more mobile and distributed and are executed in varying contexts. Context-aware access control mechanisms are an important prerequisite to protect sensitive data and services in secure ubiquitous computing environments. In an IT-supported workflow, process-related context constraints are a means to consider context information in access control decisions. A context constraint specifies that certain conditions must be fulfilled to permit the execution of a particular task. However, standard process modeling languages do not support the notion of context constraints in business processes. In this paper, we integrate context constraints with process-related role-based access control (RBAC) models and thereby support context-dependent task execution.
In the paper REF , a context-aware RBAC model for business processes is introduced.
