Blockchain-based semi-distributed vehicle violation reporting method

Abstract

The invention discloses a semi-distributed reporting method for vehicle violations based on block chain, which is applied in the field of Internet of Vehicles. In order to solve the problem that centralized reporting is prone to single-point failures, the violation records are destroyed, the system crashes, and users who violate the regulations cannot be initiated. to timely reporting of issues. The present invention is based on a semi-distributed working method. Reporting users need to centrally request identity authentication from the authentication center, and apply blockchain technology to share and store real-time violation reporting information, so that any vehicle user can query violation records in real time and receive information from the new block. message and fixes its own behavior. The invention guarantees information reliability through the identity registration process. The reporting user only needs to save the hash value of the illegal evidence file on the block chain, which reduces the communication overhead of uploading the evidence file. The invention also uses a consensus algorithm combining PoW and PoS , using the credibility of the reporting information to reduce the computational workload in the PoW algorithm and improve the throughput of real-time reporting messages.

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
