Public and Private Hybrid Distributed Cloud Storage System and Cloud Storage Method

摘要

Public and private hybrid distributed cloud storage system and cloud storage method including an application system, a segmentation aggregation system, a public storage system and a private storage system. The application system provides original complete data and initiates an access request to the segmentation aggregation system. The segmentation aggregation system divides original complete data into data fragments and distributes to said public storage system and private storage system according to a preset storage proportion and receives the fragments returned by the public and private storage systems and aggregates them into the complete data, and transfers to said application system. The public storage system manages, authenticates and stores fragments. The private system manages, authenticates, counts, controls and stores fragments. The method, based on the cloud storage system, includes logging data and reading data. This invention solves problems of limited capacity private storage systems, inadequate bandwidth and security vulnerable public storage system.

1. A public-private hybrid distributed cloud storage system, including an application system, a segmentation aggregation system, a public storage system and a private storage system, wherein
said application system is connected with said segmentation aggregation system, for provide original complete data to said segmentation aggregation system, and initiating an access request and providing user registration information to the public storage system or the private storage system through the segmentation aggregation system; and also connected to said private storage system, for controlling said private storage system; said segmentation aggregation system is connected to said public storage system and private storage system, for dividing the original complete data into a number of data fragments, and distributing said data fragments to said public storage system and private storage system according to a preset storage proportion; and connected with said application system, for receiving the data fragments returned by said public storage system and said private storage system according the access request initiated by said application system, and then aggregating said data fragments returned by said public storage system and said private storage system into the complete data, and transferring the aggregated complete data to said application system; said public storage system is configured for managing, authenticating and storing the data fragments transmitted by said segmentation aggregation system; and said private storage system is configured for managing, authenticating, storing, controlling and counting the data fragments transmitted by said segmentation aggregation system.
