step S1, executed to be, a plurality of items are saved, each of the items includes a plurality of manuscript files having file basic information, each of the manuscript files is associated with a feature value obtained by processing according to the manuscript file, a plurality of the items are associated with a first directory, and the process proceeds to step S2;
step S2, a supervised party uploads the manuscript file to an interplanetary file system, the interplanetary file system generates a unique address value according to the manuscript file, the manuscript file and the unique address value are associated one by one, and the step S3 is proceeded;
step S3, the monitored party packages the file basic information, the characteristic value and the unique address value according to the first directory and signs with a private key to obtain signature data, uploads the signature data to a block chain, the block chain processes the signature data to obtain a certificate storing number and stores the certificate storing number, and the step S4 is entered;
step S4, the administrator selects the associated item in the first directory, and obtains the corresponding certificate storage number according to the item, so as to obtain the unique address value associated with the manuscript file from the blockchain according to the certificate storage number, further obtain the corresponding manuscript file in the interplanetary file system according to the unique address value, and complete the authenticity check on the manuscript file.
8. The method for supervising a manuscript file of claim 7, wherein said step S4 comprises:
step S41, obtaining the file basic information and the first directory in the block chain according to the certificate storing number, and proceeding to step S42;
step S42, a second directory is constructed according to the basic file information and the first directory, the second directory comprises a plurality of virtual files, the virtual files are associated with the manuscript files one by one, and the step S43 is proceeded;
step S43, saving the association relationship between the plurality of virtual files in the second directory and the corresponding manuscript files and the unique address values, and proceeding to step S44;
step S44, the supervisor selects the corresponding virtual file in the second directory, and obtains the corresponding manuscript file in the interplanetary file system according to the association relationship between the virtual file, the unique address value and the manuscript file, and then step S45 is proceeded;
step S45, comparing the feature value obtained by processing the virtual file with the feature value obtained by processing the manuscript file to obtain a verification result.
9. The method for supervising a manuscript file of claim 7, wherein said step S1 is preceded by: and configuring the network environment of the interplanetary file system and the block chain in advance.
