Description

Intelligent shared cloud storage method and system
Technical Field
The invention relates to the field of cloud storage methods, in particular to an intelligent sharing cloud storage method.
Background
Cloud storage is a new concept extended and developed on the concept of Cloud Computing (Cloud Computing), and refers to that a large number of different types of storage devices in a network are integrated to cooperatively work through functions such as cluster application, network technology or distributed file systems, and the like, so that data storage and service access functions are provided for the outside. Cloud storage is a cloud computing system with storage and management of data as a core. In short, cloud storage is a storage space that is shared by storage resources, and users can access the space through any internet-enabled device at any time and place.
From research data of IDC, the market scale of China cloud service reaches about 690 hundred million in 2017, and in recent three years, the annual composite growth rate exceeds 32%, and the momentum is good. In the personal cloud storage market, with the continuous development of the internet and communication technology, the storage and sharing demands of a single user on data are continuously increased. Therefore, the demand for cloud storage in the future market will be continuously expanded, and higher requirements are continuously put on cloud storage service providers.
In recent years, the cloud storage service industry in China develops rapidly, and various large Internet companies are engaged in the product research and development in the aspect, such as Baidu, Ali, Huashi, Tencent and the like. In order to seize market share, all the large pioneer companies also join the large army of the cloud storage service. At present, the technology stacks adopted in the technical aspect of cloud storage are roughly classified into Iaas, PaaS and SaaS. In the cloud service field, the highest utilization rate is the internet enterprise, wherein the usage amount of game, e-commerce, finance, video and mobile phone enterprises is ranked in the top five. From the trend, financial clouds, video clouds, industrial clouds, and government clouds all have great market potential.
The traditional technology has the following technical problems:
currently, cloud storage provides indispensable technical support in data backup, archiving, disaster recovery, and the like. However, although the traditional cloud storage has the advantages of convenience, quickness, relatively low cost and the like, the mechanism and the storage mode of the traditional cloud storage still have various risks and hidden dangers:
1) the privacy disclosure problem. The cloud storage user can upload files such as audio and video in the equipment to the network disk quickly at any time according to own preference, and an administrator of the network disk can directly view and delete the files uploaded by the user from a platform of the server side. The data security server has low security. The cloud storage server has long been the primary target for hacker intrusion due to its special storage mode. The server stores a large amount of user data, hijacking information of large user group services is an important source of income of hackers, and the safety of the server directly influences the safety of the user data. Data security
2) The reliability of the data. The traditional private cloud storage method adopts a local backup mode, after a certain hard disk is damaged, the hard disk can be recovered through a backup disk, but when multiple hard disks simultaneously break down (such as being soaked in water, catching fire and the like), backup cannot be carried out. And the public cloud storage method faces the risk that data is deleted by mistake, and if the deleted files are not additionally backed up, the data in the network disk is permanently lost.
3) Risk of operator termination. Under the current internet environment, cloud storage service providers provide public-oriented cloud storage services, the annual capital investment is more than 5 billion yuan, and the profit mode of cloud storage provided privately is not clear. The profit model of IM and email is mature, so relevant manufacturers can continue to be free, the investment of cloud storage is at least ten times of the sum of the former two, the first problem of service integration and convention formation among manufacturers is benefit distribution, and therefore, the service providers have the possibility of stopping service due to poor operation.

The Agent is responsible for equipment and analysis management platform communication, collects non-private data state, makes analysis management platform can realize intelligent data propelling movement. The intelligent sharing cloud storage devices are interconnected through the Internet, and can provide services such as data backup and data transmission relay for the other side. When the local hardware fails, the data can be pulled from other equipment in the network through the IPFS binding ID, so that the data can be quickly recovered, and the reliability of data storage is guaranteed. When downloading hot resources, the nodes mutually assist data transmission through a P2P protocol, and the downloading speed is greatly improved.
(3) Core workflow
The IPFS-based intelligent shared cloud storage equipment is based on user requirements, aims at high safety, high reliability and low cost, adopts a decentralized architecture, and has a core work flow including data uploading and data downloading.
The data uploading steps are as follows:
firstly, splitting an original file into a plurality of file fragments, and managing by using an intelligent sharing cloud storage system.
And secondly, storing the file fragments in a local warehouse, using the generated hash value as a file version number, when the content of the file is changed, not covering the original data file, and adding a version aiming at the file, so that the reliability of data storage is further improved, and the data coverage caused by misoperation is prevented.
And thirdly, storing the file fragments to corresponding nodes by adopting the same coding mode at the positions of the data nodes, further protecting each file fragment by adopting a symmetric encryption mode aiming at the private data, and only decrypting the file fragment by using a private key bound by the equipment.
The data downloading steps are as follows:
firstly, the intelligent sharing cloud storage system generates a file fragment dependency graph.
And secondly, directly pulling the existing local file fragments, searching the storage positions of the corresponding file fragments according to the hash values by the cloud files, and pulling file data from the storage positions.
And thirdly, merging the file fragments according to the file fragment dependency graph to restore the original file. If the original file is private data, the file fragments are decrypted by using a local private key and then merged.
The core idea of the invention is to distribute the data backup in a fragmentization manner to the intelligent shared cloud storage devices of a plurality of other users, and by using the distributed accounting book technology based on the block chain, the host machine participates in idle storage resources to provide storage service to obtain rewards, otherwise, a certain expenditure is needed for data backup by using other nodes of the network. The overhead and the income are public and auditable on the blockchain, and the network automatically stores the consistency of the contract, which means that the client does not need to verify the contract and only needs to be responsible for the management of the data. Compared with the traditional centralized cloud storage device, the distributed storage system has higher-level security (private data fragment distributed storage, each fragment is independently encrypted), reliability (the device can still be recovered after being damaged), recoverability (data is subjected to version control by adopting a Hash coding table, and can be subjected to version rollback at any time), cost performance (idle resources can participate in providing services to obtain benefits, capacity can be expanded as required when needed, and benefits brought by shared services are enjoyed), and intelligence (various intelligent cloud storage optimization mechanisms and services are provided).
The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. The equivalent substitution or change made by the technical personnel in the technical field on the basis of the invention is all within the protection scope of the invention. The protection scope of the invention is subject to the claims.
