Future devices will provide basic functionalities which are used by(More)
—In this paper we describe our approach on protecting user privacy in smart environments, particularly smart homes, which we call eHomes. These are environments with devices such as sensors, computational units, actors, which are seamlessly integrated in the environment, and objects we use in our everyday life. In order to provide more convenience to its(More)
