In this abstract, we propose a secure, privacy-preserving, and realistic mobile location-based rewarding system, called LocaWard, which strives to address the above concerns. The proposed system consists of a trusted third party (TTP), mobile users (MUs), token distributors (TDs), token collectors (TCs), and a central controller (CC). The TTP issues each MU with a real identity and a corresponding certificate. A legal MU is able to obtain a location-based token when it visits a commercial entity that participates in the system, i.e., a TD. The issued tokens at various TDs have the same format but possibly different indicated values. With all the collected tokens, an MU can redeem them for beneficial rewards not only at the same store or brand stores, but also at any other retailers or commercial entities, i.e., TCs, that have joined the system. The amount of received rewards depends on the value represented by the collected tokens. Besides, the CC stores token audition information sent by TDs and provides it to TCs when required.
