Multi-cloud cooperative storage middleware system based on existing cloud storage platform

Abstract

The invention relates to the technical field of cloud storage and in particular discloses a multi-cloud cooperative storage middleware system based on an existing cloud storage platform. The multi-cloud cooperative storage middleware system comprises a client terminal and a metadata server, wherein the client terminal is connected to a cloud platform through a network and is used for authenticating users, fragmenting and distributing files, operating and managing files, distributing data, restoring fault of data, encrypting and decrypting data; the metadata server is connected to the client terminal and is used for authenticating accounts and storing a file organization directory tree, a data encrypting key and a user operation log. The multi-cloud cooperative storage middleware system is used for cooperatively storing by using the existing multiple cloud storage platforms; through comprehensive consideration of multi-cloud storage resource and network service quality, a user data self-adaption distribution and integration algorithm is disclosed; an information security safeguard mechanism with separable data storage, data management and user visit is disclosed; a data fragmentation storage and key management method based on the metadata server is provided; the problem of leakage of the cloud storage data is solved.

Description

technical field [0001] The invention relates to the technical field of cloud storage, in particular to a multi-cloud collaborative storage middleware system based on an existing cloud storage platform. Background technique [0002] With the development of cloud computing technology and the rapid replacement of computers and mobile clients, cloud storage has gradually become the first choice for network users to store data. Many domestic manufacturers such as Tencent Weiyun, Baidu Cloud Disk, and 360 Cloud Disk have launched their own independent distributed cloud storage systems. [0003] In today's information age, users of cloud storage products can only choose one of the platforms for data storage. A single cloud storage platform is fully controlled and managed by a specific service provider, and the complete control of user data by the service provider will inevitably bring about many problems. At present, users have encountered the following four problems during use: ...

AI Technical Summary

Problems solved by technology

[0004] Problem 1. Data reliability cannot be guaranteed. A single cloud storage platform is maintained independently by a manufacturer, and users store data on the storage platform. If data loss or system errors occur on the cloud storage platform, data will be lost, and the reliability of the data cannot be guaranteed. to achieve the maximum guarantee;

[0005] Problem 2. Data access cannot achieve the shortest time. The data is stored in a fixed storage provider. The user's network communication is related to the region. If it cannot be perfectly matched with the service provider's network, the access speed will be too slow , the user's network service qual
