Wireless connectivity and the widespread diffusion of portable devices raise new challenges for ubiquitous service provisioning. Mobility of users causes frequent and unpredictable changes in user location and in consequently available resources. Access control to resources is crucial to leverage the provision of ubiquitous services and calls for novel solutions based on various context information, e.g., user location, device properties, user needs, local resource visibility. This paper presents a novel access control model that proposes the adoption of context as a first-class design principle to rule access to resources. The paper proposes a context-centric access control middleware, called UbiCOSM, that dynamically determines the contexts of mobile users and effectively rules the access to them, by taking into account different types of metadata: user profiles and system/user-level authorization policies. The paper also presents a context-dependent movie-info service to evaluate the functioning of UbiCOSM.
