Embodiment 1

[0019] A blockchain-based file sharing platform, please refer to the appendix figure 1 , including the file receiving module 10, the file regularization module 20, the file storage certificate module 30 and the file sharing module 40, the file receiving module 10 receives the file scan and the file description information, the file description information records the file type, the source department and the retrieval field, the file The regularization module 20 sets a preset patch area for each file type, cuts the image of the scanned file in the preset area as the patch 61, fills the preset area with white, and copies the patch 61 several times to obtain N patches 61 copies, watermark 62 on each copy, see appendix figure 2 , the watermark 62 includes the file hash value 31 and the transaction items, the watermark 62 of the copies of the N patches 61 traverses the transaction items and may take values, and the file storage certificate module 30 extracts the hash value of the ...

Embodiment 2

[0026] A blockchain-based file sharing platform, on the basis of the first embodiment, this embodiment proposes specific improvements for the sharing of file scans. Please see attached Figure 4 , In this embodiment, the field area 71 of each file type is manually marked, the field area 71 is associated with the field name, the hash value of the extracted field area 71 is included in the partition hash value set, and the field area 71 and the patch area are extracted. The hash value of the area is included in the partition hash value set, the hash value of the partition hash value set is extracted as the file hash value 31, the partition hash value and the location of the field area 71 are associated with the file scan and stored, and the file sharing module 40 An item table is stored, and the item table records the set of field names required for handling items. When the file sharing module 40 provides a scanned copy of the file to the requester, the field area 71 that is not...

Abstract

The invention relates to the technical field of information, in particular to an archive sharing platform based on a block chain, which comprises an archive receiving module, an archive arrangement module, an archive evidence storage module and an archive sharing module, the archive ordering module sets a preset patch area as a patch for each archive type, a watermark is added to each copy of the patch, the archive evidence storage module extracts an evidence storage hash value of an archive scanning copy and uploads the evidence storage hash value to a block chain, a value of a retrieval field on the archive scanning copy is used as a retrieval key value, and the archive sharing module establishes an archive index; and after verifying the identity of the requester, the file sharing module provides the scanned file, the patch conforming to the transaction item provided by the file sharing request, the file hash value, the patch hash value set, the evidence storage hash value and the block height for the requester. The method has the substantive effects that the file management cost is reduced, and the application range of the files can be widened.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a blockchain-based file sharing platform. Background technique [0002] Archives refer to various forms of original records with preservation value directly formed by people in various social activities. Original recordability is its essential property. It is precisely because of the original record and the validity of the documents that the archives are still mainly kept in the form of paper documents. Preserving archives in paper form not only requires a dedicated venue, is expensive to keep, but also inconvenient to find and share. As a result, the archives are usually not used again after preservation, and the social benefits of the archives are difficult to exert. Blockchain is a decentralized distributed storage technology. The data stored on the blockchain is immutable, transparent and traceable, so it can provide credible proof. Combining blockchain to study new ...
