Embodiment 1

[0051] Embodiment 1: The method of depositing and verifying encrypted electronic archive files using blockchain technology is as follows:

[0052] The secure storage sub-chain system calls the interface provided by the system described in the present invention through the smart contract to submit the file meta information and chain ID. Creation time, file type, file size, archive file hash, etc., and then submit the archive meta information and chain ID to the production node;

[0053]The production node receives the archive meta information and chain ID for verification, and extracts the version number, hash value of the previous block, Merkle tree root value, and timestamp information to generate a "block header"; the production node receives the archive meta information and the archive file Data verification is performed after the package is completed, and a new "block data" is assembled after verifying the data. The new block contains "block header" and "block data"; the p...

Embodiment 2

[0056] Embodiment 2: The method of depositing and verifying non-encrypted electronic archives using blockchain technology is as follows:

[0057] The archives demand department or the supervision department calls the interface provided by the system described in the present invention through the smart contract in the safe storage sub-chain system to submit and verify the meta-information of the archive. , file number, package hash value, name of the file in the package, file creation time, file type, file size, file hash, etc. are stored in the file meta information list, and then the file meta information is submitted to the production node together;

[0058] The production node of the deposit and verification platform receives the file meta information and verification application, and performs information verification with the received file meta information and the original file meta information and chain ID;

[0059] The deposit and verification system synchronizes the nod...

Abstract

The invention discloses an electronic archive file evidence storage and verification method and system based on a block chain. The system comprises a secure storage sub-chain system, an evidence storage and verification system and a synchronization node. The intelligent contract of the secure storage sub-chain system submits the archived electronic archive meta-information and the chain ID to a production node; the production node of the evidence storage and verification system receives the file meta-information and the chain ID for verification, extracts a current timestamp, and generates a new block; the production node of the evidence storage and verification system performs alliance chain internal broadcasting on the new block and synchronizes the new block to the synchronization node;the synchronization node verifies the file meta-information in the synchronization block; the synchronization node stores file meta-information and opens a service interface; according to the invention, a blockchain technology, multiple production nodes and an automatic synchronization technology are applied, and online searchable, verifiable and traceable properties of the whole network are provided on the basis of guaranteeing the confidentiality of archive files.

Description

technical field [0001] The present invention relates to the technical field of depositing and verifying electronic archive files, in particular to a method and system for depositing and verifying electronic archive files based on blockchain. Background technique [0002] The use of the blockchain-based electronic file security storage system implements blockchain distributed file management and secure storage within a region, which cannot avoid the problem of "information islands" and is not convenient for users to consult and verify anytime and anywhere; Remote transfer of electronic files, cross-department, cross-company, cross-city, cross-region transfer of files, effective application of file data, users can check anytime and anywhere, verify the authenticity of files, and save evidence is difficult. [0003] The certificate storage application based on blockchain technology has been born, but the network-wide certificate deposit verification solution based on the blockc...
