Abstract
With the ever increasing pervasiveness of devices with functionality to provide location based services comes the increased importance and reliance upon those services to provide user privacy and security. Many techniques to facilitate privacy and security in mobile and fixed networks have been developed, but surveys of user's show that this area still has a lot of work left to do to satisfy privacy fears and help developers of such services to choose the best techniques to use. In this paper we propose a security and privacy preserving location based services development framework. The framework will allow for future development, visualisation, comparison and analysis of location based services that preserve security and privacy in order to improve user confidence in such technologies.
