Privacy Concerns in LBS exist on two fronts: location privacy and query Privacy. In this paper we investigate
issues related to query privacy. In particular, we aim to prevent the LBS server from correlating the service attribute. An
important privacy issue in Location Based Services (LBS) is to hide a user’s identity while still provide quality location
based services. Recently, highly accurate positioning devices enable us to provide various types of location -based
services. On the other hand, because position data obtained by such devices include deeply personal information,
protection of location privacy is one of the most significant issues of location-based services. Therefore, we propose a
technique to anonymize position data. In our proposed technique, the personal user of a location -based service generates
several false position data (dummies) sent to the service provider with the true position data of the user. Because the
service provider cannot distinguish the true position data, the user’s location privacy is protected. But from this method
traffic will be increase. As a solution, a diffuser can be placed between mobile unit location based services. Diffuser will
send dummy locations to LBS and true data exchange will only be happen between mobile unit and diffuser. The traffic
between mobile unit and diffuser will be decrease.
