A Privacy-Preserved Joint Group Time Scheduling Mechanism for Mobile Social Applications
Yu‐Jia Chen, Chia‐Yu Lin, Li‐Chun Wang · 2013
In this paper, we develop a privacy preserving mechanism for a scheduling service for a group of users, which can compute the joint available time based on users' calendar information. We also propose a weighted voting game with partially homomorphic encryption (WVGPHE) scheme to protect the privacy of users' calendar information as well as users' weight. Even with the privacy protection, our experimental results show that the proposed scheme is still very computational and bandwidth efficient enough to provide immediate group meeting in mobile communications environments.
