A Privacy Preserving Rental System

Abstract. Rental records contain much sensitive information on individuals, so if abused by the rental service providers, user privacy could be jeopardized. To mitigate this concern, we present a privacy preserving rental system where interests of both the users and the service provider are protected. In particular, users are enabled to engage in a rental service in an anonymous manner; however, users who keep overdue rental items are subject to anonymity revocation. Moreover, to enforce rental limit we propose a new one-show anonymous credential scheme, tailored to the scenario of on-line credential issuing.
