Abstract

The invention discloses a method for implementing file evidence storage and authentication based on a blockchain. The implementation process is as follows: firstly, configuring a blockchain network; then, performing evidence storage: performing hash on an evidence storage file by using a hash algorithm to obtain a hash value, encrypting the hash value by using an asymmetric encryption algorithm, extracting evidence storage information as a data model, assembling an evidence storage data structure according to the data model, and writing the assembled data into the blockchain network; and finally, performing authentication: performing hash on the file by using the hash algorithm to obtain a hash value, querying evidence storage data on the blockchain according to the hash value, and verifying the signature. Compared with the prior art, the method for implementing file evidence storage and authentication based on the blockchain disclosed by the invention has the advantage of high security, and has the characteristics of data disclosure and prevention of tampering based on the blockchain technology; and the privacy is good, a source electronic file is not uploaded to the network andis only stored at a file owner.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method for realizing document storage and identification based on block chain. Background technique [0002] Today, with the advancement of science and technology and the increasing economic development, people are paying more and more attention to the protection of digital assets (electronic data), so it is becoming more and more important to store and authenticate the ownership of electronic data. Traditional data storage and identification have the following disadvantages: [0003] 1. They are all carried out by a third-party organization, which leads to the need for the owner of electronic data to trust the organization without reservation. Once the third-party organization maliciously tampers with the deposit certificate and issues false identification information, it will be generated by another user. Huge loss. [0004] 2. The file will be completely store...
