Today’s technology is developing rapidly. Due to wireless communication technologies, whole world gets closer. The best way for communication is smart phone. Number of peoples has their smart phones for daily use. Now with this people are using location based services, which provides service for user who want to know their surroundings. But major issue is privacy of user and server. Existing system provides privacy for both user and server. But it is time consuming at user side because they used grid concept. So when user moves from one region to another, it gets complicated for user to execute query every time and has to follow all the procedure regarding these protocol. Also existing system didn’t play role in authentication. Number of Location Based Services is prepaid services. So authentication is necessary for a specific user because entrusted use can use these services in absence of trusted user. We proposed a major enhancement upon previous solution by introducing Authentication and Private Information Protocol to achieve secure solution for both the parties. The solution we present is efficient and practical in many scenarios. We implement our solution on a mobile device to access the efficiency of our protocol.
