Privacy-aware user interfaces within collaborative environments

ABSTRACT

The main focus of this paper is to discuss the representation of contextual information in advanced user interfaces supporting privacy awareness. Thereby, we especially consider collaborative environments which potentially provide information about users to everybody acting in the system. Users can apply Privacy-Enhancing Identity Management (PIM) in order to control which information they disclose to whom in which situation. However, since PIM must be done additionally to the actual tasks within the application, it is questionable whether users will reasonably utilize it. Therefore, a privacy-aware user interface is an important prerequisite for the broad acceptance and adequate use of PIM. We discuss which contextual information should be represented in a collaborative environment and suggest a possible representation of the selected information.
