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 user

privacy in Location Based Services provisioning. This issue

includes two controversial requirements, namely the protection

of user’s location privacy, and the Location Based Services QoS.

In this context, we propose a framework that implements a nonirreversible

algorithm, meaning that we cannot discover user’s

exact position based on provided services. The proposed

algorithm has been implemented and integrated in a mobile

services framework based on Microsoft’s Virtual Earth platform
