Vehicle data management method and device based on block chain

Abstract

The embodiment of the invention is suitable for zero-knowledge proof in transaction verification, and discloses a vehicle data management method based on a blockchain, and the method comprises the steps: enabling the identifications of N target accessories of a target vehicle to generate a first combination identification through an encryption algorithm after the identification of the target vehicle is obtained; acquiring a first block data chain of the target vehicle on a vehicle transaction platform according to the identifier of the target vehicle, wherein the first block data chain comprises the target vehicle and each transaction block of accessories forming the target vehicle from delivery to the current moment; and comparing the first combination identifier with a second combinationidentifier in the first block data chain, if the comparison result is the same, displaying the first block data chain, and otherwise, sending alarm information. The invention further correspondinglyprovides a vehicle data management device based on the block chain. By adopting the method and the system, each participation node can inquire all transaction data of the vehicle at any time, so thatthe transaction data is public and transparent, and the accuracy and traceability of the transaction data are improved.

Description

technical field [0001] The present invention relates to the technical field of blockchain, in particular to a method and device for managing vehicle data based on blockchain. Background technique [0002] At present, during the process of the vehicles and the equipment and accessories used in the vehicles from leaving the factory to sales, maintenance and destruction, the information of these vehicles and equipment and accessories is constantly updated, so as to realize the management of the vehicles and the equipment and accessories in the vehicles , this process is connected into a whole functional network chain structure, called supply chain. The supply chain revolves around the core of the enterprise, starting from supporting parts, making intermediate products and final products, and finally delivering the products to consumers through the sales network, connecting suppliers, manufacturers, distributors and end users as a whole. However, in the process of supply chain ...

AI Technical Summary

Problems solved by technology

However, in the process of supply chain management, if the data at a certain management node is artificially modified, it is difficult to find the corresponding modified point. Moreover, based on the data of the supply chain system to manage vehicles, equipment and accessories, if Internal and external personnel colluded to sell the refurbished equipment as new equipment, and the stolen vehicle was sold to the manufacturer for refurbishment. It is difficult to distinguish the existing accessories of the vehicle or the actual source of the existing vehicle, which may cause various buyers or sellers to be in this situation. Under the circumstances that it is difficult to be held accountable, or the data information part of the entire supply chain is wrong
