Abstract
Recently, 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 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 scheme based on distributed system is required for the safe and comfortable use of LBSs by mobile users. In this paper, we propose a grid-based cloaking scheme for continuous location-based services in distributed systems. The proposed scheme stores information and performs operations in a distributed manner to create a cloaking area. Finally, we show from a performance analysis that our cloaking scheme shows better performance than the existing centralized cloaking schemes.
