Abstract

Based on the location service of the mobile user, people uses location k-anonymity technology to protect the privacy of users. However, it is difficult to ensure the honest cooperation behavior of the requesting user and the collaborative user in the user collaborative k-anonymous group. Aiming at the above problems, firstly, based on the complete information static game theory, this paper analyzed the behavioral policies of requesting users and honest users, and calculated the requesting users' integrity threshold. The collaborative user decided whether to participate in the anonymous group construction according to the comparison between the request threshold and the cooperation threshold. Secondly, this paper built a reputation mechanism to combine users' recent performance with the benefits, restricted the untrustworthy behavior of the requesting users and the collaborative users who participate in the anonymous group construction. Finally, it used the blockchain to store the game process and the location information of the collaborative users. When discovering the dishonest behavior of requesting users and collaborating users, this paper would punish the dishonest users by reducing their reputation and profit. Security analysis shows that this solution can effectively protect the user's location privacy, promote the integrity cooperation between the requesting user and the collaborative user, and encourage more people to participate in the construction of the anonymous zone.
