Distributed storage network based on blockchain and implementation method thereof

Abstract

The invention discloses a distributed storage network based on blockchain and an implementation method thereof. The distributed storage network comprises an identity authentication layer, a privacy encryption layer and a storage analysis layer, wherein the identity authentication layer comprises a real name authentication unit and a data uploading unit; the real-name authentication unit is used for performing real-name authentication on nodes according to set authentication conditions and taking the nodes passing the real-name authentication as uploading nodes, and the data uploading unit is used for uploading data to the distributed storage network through the uploading nodes; the privacy encryption layer is used for performing encryption calculation on privacy data in the uploaded data; the storage analysis layer comprises a storage classification unit and a block chain storage unit, the storage classification unit is used for distributing nodes to store the encrypted data by adopting different storage schemes according to the type of the uploaded data, and the block chain storage unit is used for storing related information of the received encrypted data. According to the invention, private storage of the data can be realized, and the security of the distributed storage network is further ensured.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a blockchain-based distributed storage network and its implementation method. Background technique [0002] In the prior art, there are two types of data storage solutions: centralized storage solutions and decentralized storage solutions. Blockchain is a decentralized storage and computing technology, which generates persistent and unmodifiable records by superimposing encrypted data blocks in chronological order, and will be stored in each node of the blockchain network, It enables collective maintenance of a reliable database in a decentralized manner. Each data block contains system data within a certain period of time, and generates data fingerprints to verify the validity of its information and link to the next database block. Therefore, the blockchain has technical advantages in terms of data tamper resistance, transparency and decentralization. ...

Problems solved by technology

If personal privacy data is easily leaked when it is used, and the individual does not know it, people and organizations with ulterior motives do some bad things. Governments, enterprises, and personal data are mostly stored in plain text, and security protection is seriously insufficient. Once leaked, causing Irreparable loss, uncontrollable after the data is sent out, the government, enterprises, and individuals are inconvenient or have no motivation to share data, resulting in the problem of inability to fully cooperate
