With the development of wireless communication technologies and popularity of smart phones, many people are using location-based services (LBSs). However, since users continuously request LBS queries to LBS server by sending their exact location data, their privacy information is in danger. Therefore, cloaking area creation schemes have been proposed to protect the user’s location privacy. However, because the existing techniques generate a cloaking area in a centralized manner, an anonymizer suffers from performance degradation and security problem. Therefore, a cloaking area creation scheme based on distributed system is required for the safe and comfortable use of mobile users. In this paper, we propose a grid-based cloaking area creation scheme for continuous LBS queries in distributed systems. The proposed scheme stores information and performs operations in a distributed manner to create a cloaking area. In addition, the proposed scheme uses aggregate nodes to prevent query issuers' bottleneck. Finally, we show from a performance analysis that our cloaking area creation scheme shows better performance than the existing centralized cloaking area creation schemes.
