Blockchain Privacy-Preservation in Intelligent Transportation Systems

Abstract

Blockchain technology, on which digital currencies are based, is poised to be the most important disruption business innovation since the Internet. Today researchers and renowned companies have proposed the use of this technology in other areas such as voting, identity management, smart city, and others. Regarding smart city, car navigation systems is one of the main research directions that aims to streamline traffic and calculate travel routes. Existing applications such as Google Traffic or Waze are often used, but for users worried about their personal data, these systems are something of a black box. Using blockchain technology, in this paper we describe the architecture of a car navigation system in which personal data protection is a major concern.
