Multi-cloud fragmentation safety storage method and multi-cloud fragmentation safety storage system based on erasure coding

Abstract

The invention discloses a multi-cloud fragmentation safety storage method and a multi-cloud fragmentation safety storage system based on erasure coding. The method comprises a data storage step and a data reading step of a multi-cloud data center, and the system comprises a data fragment layer, a data scheduling layer, and a cloud service layer. The multi-cloud fragmentation safety storage method and the multi-cloud fragmentation safety storage system are advantageous in that data processed by adopting an encryption algorithm and an erasure coding algorithm is stored in a plurality of cloud data centers, and then data center hardware construction costs are saved, and a data availability reliability problem caused by the single cloud data center is prevented; file blocks are used to select corresponding cloud data centers according to responding time, and the distribution efficiency of the file blocks is improved, and then service quality of interaction between users and cloud storage systems is improved; the file blocks are stored in the plurality of cloud data centers in a dispersed manner, and metadata is stored in metadata servers, and then the monopoly of the cloud data centers is prevented, and user data cannot be stolen, and at the same time, system developers are prevented from acquiring the user data, and then the storage safety of the data of the data centers is improved.

Description

technical field [0001] The present invention relates to the technical field of cloud storage, in particular to an erasure code-based multi-cloud fragmentation security storage method and system. Background technique [0002] With the integration of emerging information technology and modern economic society, the amount of data generated by various industries is growing rapidly, and big data is rapidly gathering huge, diverse, complex and changeable data, and collecting, storing, processing and Analyzing applications, discovering patterns, extracting value, and creating wealth from massive data. Due to the huge wealth of value hidden in data, data has gradually become a basic strategic resource of a country. At the same time, the development of big data infrastructure, analysis and service technology enables enterprises to transform into data-driven institutions. Due to the importance of big data, countries, enterprises, and organizations need to build big data capabilities ...
