Context awareness, the ability to adapt to the needs of each user, is a fundamental property of pervasive computing systems. Context information is created by tracking the actions and collecting real-time user data, such as location or body temperature. As the system collects more information about its users, the quality of its context-aware services increases, and so does a potential threat to the users’ privacy if the context information is compromised. This paper surveys a wide range of existing pervasive computing systems that address this complex problem, and provides a generalized classification of privacy management techniques used by these systems. A comparative analysis of the surveyed systems and their privacy features is also presented.
