Automobile maintenance data storage method based on alliance chain

Abstract

The invention provides an automobile maintenance data storage method based on an alliance chain. At present, a traditional storage mode of the automobile maintenance data mainly adopts paper materialsand scattered local database storage, and the storage mode shows many defects in the aspects of integrity and usability of the maintenance data. According to the invention, a blockchain technology taking an alliance chain as a main part and a cloud storage technology are used, logic blockchain storage and physical cloud storage of maintenance data are realized, so that real maintenance data cannot be tampered and traceable once generated and submitted to a verification node and written into a block by a P-DPoS consensus mechanism, and a user can know the integrity of submitted data in time through a Merkle root verification method. Meanwhile, related cryptography technologies such as a public key encryption algorithm, a proxy re-encryption algorithm, an SOK protocol and the like are adopted, so that disclosure and sharing of part of maintenance data are realized under the condition of ensuring that personal identity privacy is not leaked, and great convenience is provided for a claimprocess of a user.

Description

technical field [0001] The invention relates to the technical field of secure and trusted data storage, in particular to a method for storing automobile maintenance data based on alliance chains. Background technique [0002] Car repair data is an important document for users to apply for compensation from insurance companies after traffic accidents or other unknown accidents. However, so far, there is no truly safe and credible maintenance data storage platform. Most of the maintenance data is stored in the hands of users in the form of paper materials, and some maintenance data is stored locally in the vehicle maintenance network. in the database. Such a data storage method will have the following two problems: first, the loss of paper materials will adversely affect the user's application for compensation. Second, out of interest considerations, insurance company staff or other malicious third parties may directly request the database administrator to modify or delete r...

Problems solved by technology

Such a data storage method will have the following two problems: First, the loss of paper materials will adversely affect the user's application for compensation

Second, out of interest considerations, insurance company staff or other malicious third parties may directly request the database administrator to modify or delete relevant data

[0004] At present, users, insurance companies, and auto maintenance outlets do not have a unified communication and information sharing channel. The relevant maintenance data is stored scattered and cannot be shared. It may be lost or even maliciously deleted. Therefore, there is an urgent need for an integration of the three parties on the market. Together, and to ensure that information cannot be tampered with, traceable, transparent, blockchain-based car maintenance data storage system
