Semi-distributed vehicle violation reporting method based on block chain

Abstract

The invention discloses a semi-distributed vehicle violation reporting method based on a block chain, being applied to the field of Internet of Vehicles, aiming to solve the problems that violation records are damaged, and a system crashes and violation users cannot be reported in time due to the fact that centralized reporting is prone to single-point failure. For the semi-distributed vehicle violation reporting method, based on a semi-distributed working mode, a reporting user needs to request identity authentication from an authentication center in a centralized manner, and real-time violation reporting information is shared and stored by applying a block chain technology, so that any vehicle user can inquire violation records in real time, receive an alarm from a new block message andcorrect own behaviors. According to the invention, information reliability is ensured through an identity registration process; and a reporting user only needs to store the hash value of the violationevidence file on the block chain, and the communication overhead of uploading the evidence file is reduced, and a consensus algorithm combining PoW and PoS is also used, and the calculation workloadin the PoW algorithm is reduced by utilizing the credibility of the reporting information, and the throughput of the real-time reporting message is improved.

Description

technical field [0001] The invention belongs to the field of Internet of Vehicles, and in particular relates to a block chain-based vehicle violation reporting technology. Background technique [0002] Autonomous driving technology requires vehicles to be able to process a large amount of video and image data collected in real time, and with the support of 5G technology, vehicles can exchange data with the outside world at a higher rate, all of which are aimed at improving the safety and efficiency of road traffic. If a vehicle collects real-time violation information of other vehicles while driving, as a participant in the traffic behavior, the vehicle is obliged to report the violations it has witnessed. After the violation information is recorded, on the one hand, a warning is given to the violating vehicle, and it is urged to correct the illegal behavior that may continue to occur. On the other hand, penalties are imposed on violating vehicles. [0003] The current rep...

Problems solved by technology

[0012] In order to solve the situation that centralized reporting is prone to single-point failures that lead to violation records being destroyed and the system crashing, and secondly, under the working mode of the centralized reporting system, the data center needs to process a large number of reporting messages and verify the authenticity of the reporting messages. The shortcoming of being unable to update in real time is the problem that users who violate regulations cannot be reported in a timely manner; this invention proposes a semi-distributed vehicle violation reporting method based on blockchain. On the basis of applying blockchain technology to realize distributed reporting, The consensus algorithm combining PoW and PoS is introduced, which further improves the throughput rate of reporting messages in the block, and provides support for real-time disclosure of reporting messages; the invention adds evidence summaries to reporting messages to prevent evidence from being maliciously tampered with or provided occurrence of false news
