Electronic evidence obtaining device and method based on block chain in Internet-of-Vehicles environment

Abstract

The invention provides an electronic evidence obtaining device and method based on a block chain in an Internet-of-Vehicles environment. The method comprises the following steps of S10, offline registration, S20, vehicle online identity registration, S30, real-time evidence storage and S40, query and evidence obtaining. According to the electronic evidence obtaining device and method based on theblock chain in the Internet-of-Vehicles environment, the block chain technology is used for traffic accident electronic evidence obtaining, the integrity, non-repudiation and permanence of evidence are guaranteed through the characteristics of block chain distributed data storage and the like, many problems of traditional traffic accident evidence obtaining are solved, and the evidence obtaining efficiency is high.

Description

technical field [0001] The invention relates to the field of vehicle networking application technology, in particular to a block chain-based electronic evidence collection device and a evidence collection method in a vehicle networking environment. Background technique [0002] The Internet of Vehicles (IOV) is a complex network system including its own network, vehicle-vehicle network, and mobile Internet. It takes each vehicle as the basic element, collects raw data through sensor technology, and then uses wireless communication technology to realize the information data dissemination and communication exchange of the vehicle-road-processing platform. There are three architectures for IoV communication: communication between vehicles in a vehicle ad hoc network (V2V); communication between vehicles and roadside infrastructure (RSU) (V2I); communication between roadside infrastructure (I2I). It mainly consists of the following three types of nodes: [0003] 1. Vehicle nod...
