Abstract

The invention discloses a disaster recovery cloud storage system construction method based on a block chain technology. The block chain technology is introduced in a cloud storage system construction process. The characteristics of decentration and de-trust of the block chain technology are used to realize the distribution autonomy of storage nodes in a cloud storage system and data exchange and data sharing between the storage nodes based on a consensus algorithm. Compared with the current mainstream centralized cloud service system, the method has the advantages that network nodes can establish many-to-many rather than one-to-many contact relationship, which can greatly improve the transmission efficiency of data; and in the processes of data storage, exchange, upload and download, data block packaging and anonymous exchange and an asymmetric encryption algorithm are used, which greatly guarantees the safety and reliability of the entire ecological chain of data cloud storage. Compared with the current mainstream centralized cloud service system, the method provided by the invention has the advantages that on the basis of improved data safety, the operation efficiency of the system is greatly improved, and the operating cost of a cloud storage service is reduced.

Description

technical field

[0001] The invention belongs to the technical field of cloud storage, and in particular relates to a construction method of a disaster recovery cloud storage system based on block chain technology. Background technique

[0002] Cloud storage is an extension of the concept of cloud computing. Similar to cloud computing, cloud storage refers to the collection of a large number of different types of storage devices in the network through virtualization software to work together through cluster applications, grid technology or distributed file systems. Providing external data storage and business access functions is the management and use of virtualized storage resources.

[0003] In recent years, many Internet companies have commercialized cloud storage services, such as Baidu Cloud Disk and 360 Cloud Disk, which are well-known in China. The currently widely used cloud storage system is a typical centralized system, that is, the corresponding Internet company b...

Embodiment Construction

[0026] In order to describe the present invention more specifically, the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] The present invention is based on the block chain technology disaster recovery cloud storage system construction method, the specific implementation process is as follows:

[0028] (1) Build a distributed autonomous disaster recovery cloud storage system operating framework based on blockchain technology, cancel the centralized platform that exists widely in the current cloud storage system, and realize the direct interaction between storage demand nodes (clients) and network storage nodes, This enables the entire cloud storage system to achieve decentralization and distributed autonomy.

[0029] There are a large number of data storage requirements (clients) in the network and randomly distributed storage devices willing to sell storage space. Whe...
