Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, 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.

[0032] First of all, in order to facilitate the understanding of the present invention, the technical terms involved in this solution are firstly defined and explained.

[0033] Object storage: An object is the basic unit of object storage device (OSD) processing, which is distinguished by a unique ID identifier. Each object is a collection of ordered bytes, including data and attributes. The objects in OSD are divided into root object (RootObject), partition object (Partition Object), collection object (Collection Object) and user object (UserObject). Among them, the root object corresponds to t...

Abstract

The invention discloses a cloud storage data processing method based on data self-destruction, and the method comprises a data uploading step and a data downloading step, and the data uploading step comprises the steps: S1, carrying out the encryption processing of original data through employing a secret key; S2, segmenting the secret key, randomly selecting k equal parts from the equal parts toform a data object, and respectively establishing connection with each storage node; S3, creating a storage object in the storage node, wherein the attribute of the storage object comprises survival time, and the corresponding equal secret key data are written into the storage object; S4, establishing connection with a data storage system server. The data downloading step comprises the steps thatS5, establishing connection with a data storage system server, downloading ciphertext data, and extracting key meta-information of the head of the ciphertext data; S6, establishing connection with each storage node according to the key element information; S7, reading each key equal part, storing the key equal parts into a specified array, and recombining the keys from the specified array; And S8,decrypting the ciphertext by using the secret key, and writing the decrypted data into the target file to finish downloading.

Description

technical field [0001] The invention belongs to the technical field of computer data storage, and in particular relates to a cloud storage data processing method based on data self-destruction. Background technique [0002] Traditional data destruction technologies include the following types according to different forms of operation methods: data deletion based on the file system, 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 different operation granularities. 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 manag...
