Problems solved by technology

[0002] At present, the retrieval of most systems can only obtain the information you need from one data center at a time. If the data center fails or is attacked, similar to the situation where network applications rely too much on the backbone network, there will be a problem of file loss.

Embodiment 1

[0019] Such as figure 1 A block chain file fragmentation retrieval method shown: comprising the following steps,

[0020] Step 1: Get the source file according to the file name;

[0021] Step 2: File fragment retrieval method processing, distribute the source files obtained in step 1 to the file distribution retrieval device for file fragment retrieval method processing, distribute the files processed by the file fragment retrieval method to the storage chain, and wait next step;

[0022] Step 3: Compute and store node processing. The files generated by the processed source files in step 2 are calculated and stored in the storage chain. If the calculation fails, the source files are sent back to the file fragment retrieval device. If the calculation is successful, the The source files are allocated to storage node A, storage node B, storage node C, and storage node D, and storage node A, storage node B, storage node C, and storage node D generate file slice A, file slice B, ...

Embodiment 2

[0025] As shown in Embodiment 1, a block chain file fragmentation retrieval method differs only in that the file fragmentation retrieval method processing sequentially includes file fragmentation algorithm processing, file addressing, file retrieval, calculation chain, storage, If the file addressing fails, the source file is sent back to the file slice retrieval device. If the file addressing is successful, the file retrieval is performed to obtain the file sequence; the obtained file sequence and the source file are calculated in the chain. If the calculation fails, The source file is sent back to the file slice retrieval device, and if the calculation is successful, the source file is stored in the storage chain.

[0026] Such as figure 2 As shown, the source file is obtained first according to the file name, and the source file enters the file fragmentation retrieval device, and the file fragmentation retrieval device performs file fragmentation algorithm processing and f...

Abstract

The invention discloses a block chain file fragment retrieval method, which includes obtaining source files according to file names, file fragment retrieval method processing, computing and storage node processing, combination and verification processing of fragment files, firstly obtaining source files according to file names The file, the file enters the file fragmentation retrieval device, and the file fragmentation retrieval device sequentially performs file fragmentation algorithm processing, file addressing, file retrieval, calculation chain, and storage on the file, and the stored file will be processed by the calculation storage node to obtain For the corresponding file slices and file sequences, the file slices are finally processed and verified by the fragmented file combination method, and the files are returned to the file slice retrieval device. The block chain file segment retrieval method of the present invention divides a large file into several small files, which can be obtained from multiple servers at the same time when downloading, preventing the problem that the server fails and cannot be downloaded, and has the advantages of high security and wide applicability advantage.

Description

technical field [0001] The invention relates to a file retrieval method, in particular to a block chain file fragment retrieval method. Background technique [0002] At present, the retrieval of most systems can only obtain the information you need from one data center at a time. If the data center fails or is attacked, similar to the situation where network applications rely too much on the backbone network, the problem of file loss will occur. Therefore, it is necessary to design a block chain file segment retrieval device, which can be obtained from multiple servers at the same time, and can share various types of data well. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a block chain file segment retrieval method for the above-mentioned deficiencies in the prior art. [0004] The present invention achieves the above object through the following technical solutions: a block chain file fragment retrieval meth...
