Safe Distance Based Location Privacy in Vehicular Networks

To enhance driving safety in vehicle ad-hoc networks (VANETs), vehicles periodically broadcast safety messages with information of their precise positions to others. These broadcast messages, however, make it easy to track vehicles and will likely lead to violations of personal privacy. Unfortunately, most of the current location privacy enhancement methodologies in VANETs suffer some shortcomings and do not take driving safety into consideration. In this paper, we propose a safe distance based location privacy scheme called SafeAnon, which can significantly enhance location privacy as well as traffic safety.
