Embodiment Construction
[0052] The specific embodiments of the present invention are described below so that those skilled in the art can understand the present invention, but it should be clear that the present invention is not limited to the scope of the specific embodiments. For those of ordinary skill in the art, as long as various changes Within the spirit and scope of the present invention defined and determined by the appended claims, these changes are obvious, and all inventions and creations using the concept of the present invention are included in the protection list.
[0053] Such as figure 1 As shown, a fragmented content similar storage method includes the following steps:
[0054] S1. Perform preprocessing on all file fragments x of each server to obtain the average value set E of the fragment content of the server;
[0055] S2. Cut the file f to be stored into n file fragments f i ;
[0056] Among them, i=1,2,3,...,n;
[0057] S3. Build a file storage table S_List in the local ser...

The invention discloses a fragmented content similar storage method, and the method is characterized in that fragmented decentralized storage is carried out on a to-be-stored file, no complete file exists in any server, the secrecy and security of the file are ensured, and meanwhile, the decentralized storage effectively avoids the risk caused by centralized storage; through the utilizattion of the file fragment content, redundant encryption and Hash calculation on fragments are removed, calculation cost is reduced, and compared with traditional name positioning or Hash positioning, positioning speed is greatly increased according to content positioning; the file fragments of the servers are uniformly arranged, and the file storage table is constructed, so the to-be-stored file is quickly generated, directly read, spliced and verified once, and the integrity of the file is ensured while the reading speed is shortened.
Description
technical field [0001] The invention belongs to the technical field of network data processing, and in particular relates to a similar storage method for fragmented content. Background technique [0002] Today, with the rapid development of cloud computing platforms, cloud storage technology has been gradually popularized and applied. It is a new concept extended and developed from the concept of cloud computing. It is an emerging network storage technology. , network technology, distributed file system and other functions, a system that integrates a large number of different types of storage devices in the network through application software to work together and jointly provide data storage and business anti-counterfeiting functions. When the core of cloud computing system computing and processing is the storage and management of large amounts of data, a large number of storage devices need to be configured in the cloud computing system, then the cloud computing system wil...
