A Framework for Preserving User Privacy and Ensuring QoS in Location Based Services using Non-irreversible Algorithm

Abstract

In this paper, we address the issue of preserving userprivacy in Location Based Services provisioning. This issueincludes two controversial requirements, namely the protectionof user’s location privacy, and the Location Based Services QoS.In this context, we propose a framework that implements a nonirreversiblealgorithm, meaning that we cannot discover user’sexact position based on provided services. The proposedalgorithm has been implemented and integrated in a mobileservices framework based on Microsoft’s Virtual Earth platform
