Group Communication Needs No Consistent Transcript Distribution

Abstract

Instant Messaging (IM) clients are lying to you about groups and their consistency. None of the so called secure chat applications provide the same security properties for group communication you know from face-to-face meetings. In this paper we give an overview of the challenges in group communication and introduce a solution to the transcript distribution challenge. We present a new visualization for out-of-order messages and the results of a user study to show that our approach is working for every day users.
