With the growing advancement of ubiquitous computing (UbiComp), we are moving towards an era where access control and security policies will be based on context information. As context information represents real-world situations, it is associated with certain quality indicators that can directly influence the access control decisions. In this paper, we propose a quality-aware context-based access control model that takes into account the context information and its QoC indicators to grant and to adapt access permissions to resources.
