Privacy-Enhanced Web-Based Event Scheduling with Majority Agreement

摘要

Applications which help users to schedule events are becoming more and more important. A drawback of most existing applications is, that the preferences of all participants are revealed to the others. Previously proposed privacy-friendly solutions could only schedule meetings if all participants were available at the same time slot. We propose a new scheme, which overcomes this limitation, i.e., the meeting can be scheduled at the time slot, where just the majority of participants is available. Dudle (http: //dudle. inf.tu-dresden.de), a web-application which implements the protocol is presented. We measured its performance in order to show that the protocol is practical and feasible.
