Embodiment 1

[0019] A blockchain-based file management system, please refer to the appendix figure 1 , including the receiving module 10, the certificate storage module 20, the storage module 30 and the time-limited sharing module 40, the receiving module 10 receives the scanned file 11 and the description information 12 of the file, the description information 12 includes the file type and the query key value, and the certificate storage module 20 extracts The hash value of the scanned part 11, upload the hash value to the blockchain 50 for storage, obtain the corresponding block height, the storage module 30 stores the scanned part 11, the storage module 30 establishes the index of the scanned part 11, and the index records the file storage address, File type, query key value, hash value and height of storage certificate block, the time-limited sharing module 40 receives read requests from other departments, and the read request includes department information, retrieval key value, type a...

Embodiment 2

[0035] A blockchain-based file management system, this embodiment specifically improves the smart contract used for time-limited encryption. As shown in Table 4, the encrypted column of the smart contract in this embodiment also includes a second clock and a prompt column.

[0036] Table 4 Smart Contracts

[0037] Encryption column 1 {column ID 1, clock 1, second clock 1, prompt column 1, bulletin column 1} Encryption column 2 {Column ID 2, Clock 2, Second Clock 2, Prompt Column 2, Public Column 2} Encryption column 3 {Column ID 3, Clock 3, Second Clock 3, Prompt Column 3, Public Column 3} … … Encryption column 60 {column logo 60, clock 60, second clock 60, prompt column 60, bulletin column 60}

[0038] The prompt bar is initially hidden. When the second clock counts down to 0, the prompt bar is displayed and the clock is started. When the clock counts down to 0, the clock and the second clock are reset.

[0039] Please see attached ...

Abstract

The invention relates to the technical field of information, in particular to a block chain-based archive management system, which comprises a receiving module, an evidence storage module, a storage module and a time-limited sharing module, and is characterized in that the receiving module receives a scanned copy and description information of an archive, the evidence storage module extracts a hash value of the scanned copy, and the storage module stores the scanned copy; the storage module establishes an index of the scanned copy, the time-limited sharing module receives reading requests of other departments, the time-limited sharing module reads the scanned copy with a query key value conforming to a retrieval key value and an archive type conforming to the archive type after verifying that the departments have the authority of handling corresponding items, watermarks containing item information are added to the scanned copy, and the scanned copy is stored in the storage module; and encrypting the scanned copy by using a time-limited encryption algorithm to obtain a time-limited ciphertext, sending the time-limited ciphertext to a requesting department, and decrypting the time-limited ciphertext by the requesting department within a limited time to obtain a file. The method has the substantial effects that the file management cost is reduced, and the efficiency of handling related items by departments is improved.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a block chain-based file management system. Background technique [0002] Archives are documents for recording rights and interests, and have original recordability. In the event of disputes over rights and interests, the files will serve as an important basis for investigation. Precisely because of the original record and the validity of documents, the current 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 non-tamperable and transparent and traceable, so it can provide credible proof. Provid...
