Abstract
Abstract: Ubiquitous computing provides new types of information for which access needs to be controlled. For instance, a person’s current location is a sensitive piece of information, and only authorized entities should be able to learn it. We present several challenges that arise for the specification and implementation of policies controlling access to location information. For example, there can be multiple sources of location information, policies need to be flexible, conflicts between policies might occur, and privacy issues need to be taken into account. Different environments handle these challenges in a different way. We discuss the challenges in the context of a hospital and a university environment. We show how our design of an access control mechanism for a system providing people location information addresses the challenges. Our mechanism can be deployed in different environments. We demonstrate feasibility of our design with an example implementation based on digital certificates.
