A Secure Framework for User Privacy in Heterogeneous Location Networks

A heterogeneous location network is one that derives location information from multiple sources and provides various location based services to users irrespective of the device used. User privacy is an important issue that needs to be addressed for the growth of heterogeneous location networks. We propose a secure framework for assuring user privacy in heterogeneous location networks. We also present lightweight cryptographic protocols along with an analysis of the computation requirements and security capabilities of the proposed framework.
