A multi-cloud collaborative storage middleware system based on the existing cloud storage platform

Abstract

The invention relates to the field of cloud storage technology, and specifically discloses a multi-cloud collaborative storage middleware system based on an existing cloud storage platform, including: user authentication, file fragment distribution, file operation and Clients for management, data distribution, data recovery, and data encryption and decryption; also include metadata servers connected to clients for account authentication, storage of file organization directory trees, data encryption keys, and user operation logs. The present invention utilizes various existing cloud storage platforms for collaborative storage, comprehensively considers multi-cloud storage resources and network service quality, proposes user data adaptive distribution and integration algorithms, and proposes separation of data access from data management and user access The information security guarantee mechanism based on the metadata server is given for data fragmentation storage and key management methods, which overcomes the problem of cloud storage data leakage.

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 quality will drop significantly;

[0006] Question 3: Cloud storage service providers tend to monopolize data, and user data is stored on a single cloud storage platform, which can easily be completely controlled by the cloud storage provider to form a monopoly, and users cannot protect their legitimate rights and interests in terms of storage payment;

[0007] Question 4. The privacy and security of data cannot be protected. Data is stored on the cloud storage platform. The super administrator of the cloud storage service provider cloud platform has the authority to view all platform data. User data may be completely peeped, and user data privacy cannot be guaranteed
