Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] First of all, in order to facilitate the understanding of the present invention, the technical terms involved in this scheme are first defined and explained.

[0029] Object storage: An object is the basic unit of object storage device (OSD) processing, and is distinguished by a unique ID identifier. Each object is a collection of ordered bytes, including data and attributes. The objects in the OSD are divided into Root Object, Partition Object, Collection Object and User Object. Among them, the root object corresponds to the OSD, and each OSD contains only one root object, which is cre...

Abstract

The invention discloses a cloud storage data system based on data self-destruction. The cloud storage data system includes a client, a metadata server and a plurality of storage nodes, wherein the client is used for encrypting, uploading, downloading and decrypting data and comprises a data encryption module, a Key splitting and reassembly module, a data decryption module and a communication module; the data encryption module is used for carrying out encryption processing on original data through a given key; the key segmentation and recombination module is used for segmenting the key in datauploading, generating a plurality of equal parts and randomly selecting part of or all of the equal parts from the equal parts to form a data object; The communication module is used for establishingconnection and data transmission between the client and each storage node; The data decryption module is used for decrypting the downloaded data through the regenerated key; The metadata server is used for generating metadata information of each divided key equal part on each corresponding storage node; And each storage node is used for creating a storage data object according to the established connection so as to store the encrypted data.

Description

technical field [0001] The invention belongs to the technical field of computer data storage, and in particular relates to a cloud storage data system based on data self-destruction. Background technique [0002] Traditional data destruction technologies include the following types according to different forms of operation methods: file system-based data deletion, data overwriting, and physical level destruction. Among them, the data deletion based on the file system is divided into file deletion and device formatting according to the different operation granularity. File deletion is the most direct way to delete data. It uses the methods provided by the file system to explicitly delete files or data. In mainstream file systems, file deletion only deletes the corresponding index of the file, and does not correspond to the file data. Delete the disk sectors; device formatting is to use the formatting tool provided by the file system or a third-party disk management tool to f...
