Block chain-based information-authenticating and source-tracing method and system

Abstract

The invention discloses a block chain-based information-authenticating and source-tracing method. The method comprises the steps of (1) acquiring the copy of the original information to be issued by an original information publishing end; (2) generating the hash value of the copy and picking the content information of the copy at the same time; (3) creating the first transaction information based on the content information of the copy and the hash value of the copy; (4) writing the first transaction information into a center database and a block chain, or writing the first transaction information into the block chain; (5) acquiring the transshipment information released by a information transshipment end, and generating the hash value of the transshipment information; (6) comparing the hash value of the transshipment information with the hash value of the copy; if the two hash values are the same, returning a first voucher for representing the information to be true or non-tampered; if the two hash values are not the same, not returning the first voucher or returning a second voucher for representing the information to be not true or tampered. The invention further discloses a corresponding system. According to the invention, the information authentication and the source tracing can be reliably realized.

Description

technical field [0001] The present invention relates to an information authentication and traceability method and system, in particular to a blockchain-based information authentication and traceability method and system. Background technique [0002] With the rapid development of information science and network technology, more and more people are connected to the Internet. In 2010, the number of Internet users in China was 457.3 million. By the end of 2016, the number of Internet users in China had reached 648.75 million. The growth of 200 million people. From the perspective of the number of Internet users alone, there is no doubt that China is the largest country on the Internet. [0003] The huge scale of Internet users has led to more and more information being widely disseminated on the Internet, and the amount of information generated by major social media has grown at the PB level. Due to the fact that most of the online information is released under the non-real n...

Problems solved by technology

[0005] The traditional traceability method needs to label each recorded news and store it on a central server, which will cause problems such as huge data volume, easy to be tampered with, and easy to be attacked
