In a real world meeting, sometimes it is required to use secret documents which are used during the meeting, but are not premitted to bring back. Such a function is very hard to be realized by distributed meeting systems consisting of computers and networks. Participants of the meeting cannot usually access the material after the meeting. The requirements of such security meeting are contrary to the open connectivity of distributed environments. Thus, the security meeting remains in old styles that the participants come together at a restricted meeting room with their authorizations. In this paper, we discuss constraints to use the secret material on a distributed security meeting, and propose the strictly restricted meeting system which controls action and state of meeting participants with supporting multi-level security. The architecture of the proposed system is called SDMS (Secure Distributed Meeting System), and its requirements to be realized on the Sever-Client model are described.
