Abstract

In Location Based Services (LBSs), service providers can obtain mobile users' locations or traces while receiving their service requests. K-anonymity, which is the most commonly used location privacy protection method, needs the cooperation among mobile users to form a k-anonymous group. Though several incentive mechanisms have been proposed to motivate mobile users to participate in the k-anonymous group, most of them rely on a `trustful' center. In this paper, we propose a distributed secure incentive mechanism that applies blockchain smart contracts to motivate users for k-anonymity cooperation. To protect the reward transaction information, group encryption and blind collective signature are adopted. The simulations demonstrate the effectiveness of our proposed incentive mechanism.
