Secure storage method based on different cloud storage ends

Abstract

The invention discloses a secure storage method based on different cloud storage sides. The method comprises a step for storing the data to different cloud storage sides from a user side, to be specific, step 1: communicating the user side with a plurality of cloud storage sides, and also communicating the user side with an index server; step 2: processing the data to be uploaded to the cloud storage sides by the user side, to be specific, fragmenting the data into a plurality of data fragments in predetermined size, forming a processing rule in the processing process, and recording and saving the processing rule; step 3: transmitting the processed data fragments to different cloud storage sides to be saved according to a predetermined storage rule; and step 4: integrating the processing rule in the step 2 and the storage rule in the step 3 to form an index management list, and storing the index management list to the index server, wherein the index management list describes the processing way for the data which is uploaded by the user side to the cloud storage side and a storage address of the processed data in different cloud storage sides.

Description

technical field [0001] The invention belongs to the technical field of cloud storage services, and relates to a safe and confidential storage method across different cloud storage terminals. Management, enabling users to safely and confidentially manage storage technologies using various file data anytime, anywhere. Background technique [0002] With the explosive growth of data such as photos and videos on the client side, an easy-to-use data storage management method has become an urgent problem to be solved. Data loss due to accidental hardware damage, unified management of data, and ease of use have become headaches for people. [0003] Therefore, at present, many storage service providers (each storage service provider provides a cloud storage terminal) provide cloud storage services for individuals or enterprises, provide configurable virtual storage and related data services through the Internet, and provide users with a good Data management platform; currently, the...

Problems solved by technology

Although this invention improves storage security to a certain extent, it requires individual users of the first network to transmit the data to be saved to the system provided by the invention—the third-party data security protection system, through which the data security protection system processes Then it is transmitted to the cloud storage terminal of the second network, there is a problem of trust in the service provider that provides data security protection, and there are also security risks such as the confidentiality of data storage and communication, and the problem of data isolation
