A Vehicle Information Authentication Method of Expressway Based on Heterogeneous Blockchain Technology

With the continuous development of expressways' convenient and unconscious toll collection, it is crucial to improve the accuracy of highway vehicle authentication while reducing the time delay of highway vehicle charging. Based on the characteristics of multi-body and multi-stage operation status of highway vehicles, starting from the dynamic authentication of highway vehicle driving process, we propose the highway reliable driving trajectory authentication based on heterogeneous blockchain technology. It realized the real-time inspection of vehicle information and the reliable track authentication of expressway vehicles based on track information chain association.
