A Secure Web Services for Location Based Services in Wireless Networks

摘要

While Location Based Services (LBS) can make our lives more comfortable and productive, it may cause an invasion of privacy by disclosure and commercial use of location information. In this paper, we discuss privacy and security problems that may happen in the current LBS system and propose solutions. We propose a new secure Web services architecture for LBS in wireless network. Our architecture allows mobile users to create and enforce dynamic policy for safe and consistent LBS. We also describe some practical scenarios in which our architecture protects user's location privacy and security.
