Supporting Distributed Decision Making Using Secure Distributed User Interfaces
In disaster situations people with different roles are cooperating to solve emerging problems. Cooperative systems providing enhanced interaction facilities in the user interface (e.g. direct manipulation techniques) could substantially support decision making especially for geographically distributed cooperating teams. Thereby, sensitive information has to be shared in a common workspace requiring different handling procedures according to the different roles involved in the process. In this paper, we propose the use of a common multilaterally secure distributed user interface to support the decision making in geographically distributed groups of professionals. The system combines a collaborative multi-pointer system with an anonymous credential security system to provide users with an easy way to share and access information in a secure way ensuring the privacy.
