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 queries to LBS server by using their exact locations, their privacy information could be in danger. Because the existing techniques providing user's privacy protection operate on centralized system, an anonymizer suffers from performance degradation and security problems. Therefore, a mechanism based on distributed system for users' privacy protection is required for the safe and comfortable use of LBSs by mobile users. For this, we, in this paper, propose a distributed grid-based cloaking scheme to support continuous query processing in LBSs. The proposed scheme stores information and performs operations in distributed manner to create a cloaking area. In addition, the proposed scheme uses merge nodes to prevent service users' bottleneck. Through performance analysis, we show that our cloaking scheme outperforms the existing centralized based cloaking schemes, in terms of service time. |
