File storage and authentication method, system and device based on block chain, and medium

Abstract

The invention relates to a file storage authentication method, system, and device based on a block chain, and a medium, and the method comprises the steps: creating a distributed file storage networkand a block chain network, and deploying a file management interface; receiving a storage file, uploading the storage file to the distributed file storage network for storage, and receiving an initialcheck code returned by the distributed file storage network when uploading is successful; the file management interface uploading the initial check code corresponding to the storage file to a block chain network and stores the initial check code; and reading the current check code of the authentication file from the block chain network, and determining that the to-be-authenticated file is not tampered when the current check code is the same as the corresponding initial check code. According to the method, the block chain network cannot be tampered and the distributed file storage of the filestorage system is skillfully combined, so that the distributed storage of the file is realized, the file can be accurately informed when being tampered, and the performance of the file is not influenced along with the increase of access users, so that the file storage function of the block chain network is realized.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a file storage identification method, system, medium and device based on block chains. Background technique [0002] Blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. It involves container technology, storage technology, encryption technology, P2P communication technology, PKI technology, consensus algorithm, etc. To a certain extent, the threshold for enterprise entry has been increased. Blockchain has many advantages, such as decentralization, distributed storage, inability to tamper and content encryption, etc., but it cannot store files on the blockchain network. This drawback also limits the implementation of related blockchain projects. The existing solution is to centrally store the files in a centralized file system for everyone to access....

AI Technical Summary

Problems solved by technology

Blockchain has many advantages, such as decentralization, distributed storage, inability to tamper and content encryption, etc., but it cannot store files on the blockchain network. This drawback also limits the implementation of related blockchain projects. The existing solution is to centrally store the files in a centralized file system for everyone to access. Since the files are stored in a centralized manner, there is a risk of tampering with the files, and the authenticity of the files cannot be verified. Moreover, as the number of visitors increases, its performance It is also getting lower and lower, and this is contrary to the idea of ​​blockchain decentralization
