摘要：The fact that pervasive systems are typically embedded and invisible makes it difficult for users to know when, where, and how these devices are collecting data. So privacy is a major issue for pervasive computing applications and several privacy models have been proposed for pervasive environments. In this paper we present a XML based User-centered Privacy Model (UPM) which provides content, identity, location, and time privacy with low unobtrusiveness.
