Abstract(in English) In crowdsensing, since the data gathered by the server includes user's GPS locations and moving paths, the anonymity of users is desired. However, the data reliability is lost if a user sends incorrect data anonymously and the user cannot be traced or deleted. Therefore, as the system to achieve both anonymity and trust, the anonymous reputation systems have been proposed. But the user revocation is not considered in these systems. In this study, we propose a revocable anonymous reputation system and evaluate its performance.
