In this paper, we propose P-3-coupon, a Prompt and Privacy-preserving electronic coupon distribution system based on a probabilistic one-ownership forwarding algorithm. In this algorithm, only one hop of forwarder (coupon owner) information instead of the complete forwarder list is recorded to keep the coupon short and privacy-preserving. Such information is updated probabilistically following two ownership flipping models, namely, one-Flip and Always-Flip models. We also use a Bluetooth Service Discovery Protocol (SDP) toolkit to enable fast, configuration-free coupon exchange. We have implemented the system in Java ME. Our experiments on real world mobile phones, such as Nokia and Samsung phones, and large scale simulations show that our system is efficient in peer to peer coupon distribution and capable of massive deployment. We believe our key methodology can serve as a general framework for facilitating information propagation on mobile phones, which requires promptness and privacy protection.
