As the mobile networks are springing up, mobile devices have become a must gadget in our daily life. People can easily access Internet application services anytime and anywhere via the hand-carried mobile devices. Most of modern mobile devices are equipped with a GPS module, which can help get the real-time location of the mobile device. Location based services (LBS) aim at delivering point of need information. Personalization and customization of such services, based on the profiles of mobile users, would significantly increase the value of these services. The term Location Based Services (LBS) refers to mobile services in which the user location information is used in order to add value to the service as a whole. The user location information in that case consists of X-Y coordinates generated by any given Location Determination Technology (LDT), such as Cell-ID, A-GPS, EOTD, etc. Since profiles may include sensitive information of mobile users and moreover can help identify a person, customization is allowed only when the security and privacy policies dictated by them are respected. Systems which provide location based services have always been vulnerable to numerous privacy threats. The more we aim at safe usage of location based services, the more we feel the necessity of a secure location privacy system. In this paper I present the privacy and security issues, along with the threat of location cheating attacks, find the root cause of the vulnerability, and outline the possible defending mechanisms. Design and implementation of solution for these issues.
