Embodiment 1

[0034] Such as figure 1 As shown, the present embodiment provides a blockchain-based steel material warranty privacy protection and sharing method, the method comprising the following steps: building a blockchain platform (quality assurance privacy protection system), steel production institutions (steel mills) and The steel sales organization (electricity business trading platform) accesses the block chain platform based on unique identity authentication information, and the unique identity authentication information includes identity code identity_key and key pair (public and private public_key and private key private_key); block chain platform Receive the steel resource information resource_info, quality assurance information quality_info, and quality assurance document description information (excluding the original document) quality_file_info uploaded by the signature of the steel production organization, and simultaneously save the encrypted quality assurance document qua...

Embodiment 2

[0049] This embodiment provides a blockchain-based steel material warranty privacy protection and sharing system, including: a blockchain platform for realizing information interaction between steel production organizations and steel sales organizations, using the method described in Embodiment 1 Privacy protection and sharing of steel warranty documents; and a distributed file storage module for storing encrypted warranty documents.

[0050] The blockchain platform is connected to multiple steel production institutions, and the data management of steel factories will be realized by data privacy protection. A steel factory cannot access the quality assurance documents of other steel factories. In the steel mill data management, the steel mill can upload the quality assurance information and warranty certificate at one time, and the steel material guarantee data is presented to the buyer in different forms before and after the buyer purchases. The overall business logic and auth...

Abstract

The invention relates to a steel quality guarantee book privacy protection and sharing method and system based on a block chain. The method comprises the steps that a block chain platform is constructed, and a steel production institution and a steel sales institution are accessed to the block chain platform based on unique identity authentication information; the block chain platform receives thesteel resource information, the quality guarantee information and the quality guarantee document description information which are signed and uploaded by the steel production institution, and storesthe encrypted quality guarantee document into a distributed document storage module; the block chain platform feeds back corresponding quality guarantee information when receiving a query request of the steel sales institution; and after receiving purchase confirmation information of the steel sales institution, the blockchain platform calls a corresponding encrypted quality guarantee document from the distributed file storage module in response to a download request and feeds back the encrypted quality guarantee document, and the encrypted quality guarantee document is downloaded by a purchased user after being decrypted. Compared with the prior art, the method has the advantages of high information security and the like.

Description

technical field [0001] The present invention relates to the technical field of manufacturing and information technology in the steel industry, and in particular to a method and system for privacy protection and sharing of steel material guarantee documents based on blockchain. Background technique [0002] Each steel product will be accompanied by a quality assurance certificate when it leaves the factory, indicating the specifications and performance parameters of the raw materials used, and providing the test report or results of the main performance indicators, which has legal effect. At present, most of the steel factory warranty PDF files are stored locally in the steel factory. A small number of steel factories provide the data to the steel e-commerce trading platform through interface docking. Some steel factories only provide the website of their second-party steel factory sales platform, and users log in and download it. . In the steel e-commerce trading platform, ...
