A security scheme for geographic information databases in location based systems LBS (Location-based Services) are ubiquitous nowadays; they are used by a wide variety of applications ranging from social networks to military applications. Moreover, smart phones and hand held devices are increasingly being used for mobile transactions. These devices are mostly GPS-enabled and can provide location information. In some cases, the geographical location of clients as an authentication factor is integrated with applications to enhance security. But for attackers it is easy to forge location information, thus the security of geographical information is a critical issue. In this paper we discuss geographical database features and we propose an effective security scheme for mobile devices with limited resources.
