In general security in every area counted so security issues related to location based services are mandatory without it our application devices are not perfectly reliable . We are proposing a new technique that uses user anonymity and dummy locations for location privacy while using location aware application server. User communicates with the server through a trusted proxy server. It sends dummy locations to the application server with its original position. The user uses temporary pseudonyms that are changed frequently according to some algorithm. Whenever pseudonyms are changed by a user, dummy locations are chosen in a tricky fashion. By the mathematical formula of path and number of dummies that makes the task of tracing the user very difficult. Security of user location will be hence increased. Keywords- Location privacy, pseudonym, de-anonymize, dummy-Locations, location anonymity, trusted proxy I. INTRODUCTION The Indian Constitution of 1950 does not expressly recognize the right to privacy. However, the Supreme Court first recognized it in 1964 that there is a right of privacy implicit in the Constitution under Article 21 of the Constitution, which states, "No person shall be deprived of his life or personal liberty except according to procedure established by law." The 1948 Universal Declaration of Human Rights [1] declares that everyone has a right to privacy at home, with family, and in
