Abstract
The current architecture for VANET related services relies on a Client-Server approach and leads to numerous drawbacks. Among them, data privacy concerns and service availability are of prime importance. Indeed, user data collected and stored in servers by providers may be used by third-party services. Particularly for navigation, users submit their GPS position in order to obtain road traffic information and alternative paths. These services treat user privacy for their own purpose (commercial or not) (Beresford and Stajano, 2004) even if GPRD (European Parliament, 2014) is now enforced in Europe. We propose an innovative approach using blockchain technology to avoid the use of third parties services, which enable dynamic navigation rerouting within a fixed geographic zone while ensuring user anonymity. Furthermore, the approach will allow for legal authority to enable forensic analysis of the ledger without unnecessary violation of the user anonymity and privacy.
