Abstract

Embodiments of the present application discloses an information authentication method, which includes: generating first transaction information based on content information of first information to be published by an original information publishing end and a HASH value of the first information, wherein the first information is original 5 information or a copy of the original information; writing the first transaction information into a central database and Blockchain, or into the Blockchain; obtaining reprinted information published by an information reprinting end, and generating a HASH value of the reprinted information; comparing the HASH value of the first information with the HASH value of the reprinted information; and returning a first credential, which indicates 10 the reprinted information is true or has not been tampered with, to the information reprinting end, if the HASH value of the first information is equal to the HASH value of the reprinted information. 15
