Abstract

The invention provides a file multi-cloud storage method and device, a file multi-cloud downloading method and device and a storage medium. The multi-cloud storage method of the file is applied to encryption distributed storage equipment. The file multi-cloud storage method comprises: segmenting an original file to be uploaded to the cloud for storage into a plurality of cascaded sub-files throughthe encryption distributed storage device, the cascade sub-files being stored in the cloud; then encrypting the cascade sub-files, and uploading the cascade sub-files to the corresponding cloud for storage according to the preset weight, so that any cloud storage provider cannot analyze the original file, and the security of the cloud storage file is improved. Besides, the encryption key and thefile splicing rule are stored in the encryption distributed storage device, so that lawbreakers obtaining all the sub-files cannot decrypt and splice the original file, the security of cloud storage data is further improved, and the technical problem that existing cloud storage data is prone to leakage is solved.

Description

technical field [0001] The present invention relates to the field of network storage, in particular to a multi-cloud storage method, device, and computer-readable storage medium for files, and a download method, device, and computer-readable storage medium for multi-cloud storage files. Background technique [0002] With the rapid development of cloud storage technology, cloud storage applications such as storage into the cloud have become more and more common. Users or enterprises can store related applications or data in the cloud, no longer limited by time or geographical conditions. Therefore, cloud storage technology brings users a convenient and fast experience. However, storing applications and data in the cloud will also bring many problems. For example, data entering the cloud inevitably increases the risk of leakage of private data. Therefore, data security issues have become an obstacle for users or enterprises to enter data into the cloud. Contents of the inven...
