Anti-tamper official document transmission and storage method based on block chain

Abstract

The invention discloses an anti-tamper official document transmission and storage method based on a block chain. Through utilization of an automatic encryption security mode of the block chain, electronic official document hash values are stored to various nodes of the block chain; the electronic official document bodies are stored to various nodes of a document server distributed network; the system automatically monitors and checks electronic official documents and corresponding hash values; and through utilization of the document server distributed network, tampered electronic official documents in a document server are automatically and synchronously restored. According to the method, the problem of identifying whether the electronic official documents are tampered or not can be solvedfundamentally and the tampered electronic official documents can be automatically restored.

Description

technical field [0001] The invention relates to the field of information, can be used in the transmission and storage of electronic documents, and ensures that the electronic documents are tamper-proof. Background technique [0002] In the existing electronic document transmission process, the official document system is uploaded through attachments. The electronic official documents on the server are also stored randomly, resulting in the following technical problems that need to be improved and solved in the electronic official documents. [0003] 1. The existing storage method of electronic documents leads to arbitrary modification of electronic documents, and the traces cannot be traced after modification, which greatly reduces the effectiveness of electronic documents in government affairs, and the electronic documents issued and circulated by courts and other agencies are deemed invalid . [0004] 2. The current electronic documents are stored on a single server, or ...

Problems solved by technology

[0003] 1. The existing storage method of electronic documents leads to arbitrary modification of electronic documents, and the traces cannot be traced after modification, which greatly reduces the effectiveness of electronic documents in government affairs, and the electronic documents issued and circulated by courts and other agencies are deemed invalid

[0004] 2. The current electronic documents are stored on a single server, or directly shared with other servers

The current situation is that only the last version of the electronic document will be kept, but when it is necessary to find the previous version, it can no longer be found
