Block chain based anti-counterfeiting method and system

Abstract

The invention discloses a block chain based anti-counterfeiting method and system. The method includes: acquiring characterization data and materialization data of a material object requiring anti-counterfeiting processing; combining the characterization data and the materialization data of the material object to obtain transaction data; writing the obtained transaction data into a block chain system; querying in the block chain system according to user query instructions, and performing anti-counterfeiting checking according to query results. Problems of data modification, tampering and damaging in material anti-counterfeiting processing are solved by anti-counterfeiting, anti-tampering, openness, transparency and credibility characteristics of block chains.

Description

technical field [0001] The present invention relates to the field of computer application technology, in particular to a blockchain-based anti-counterfeiting method and system. Background technique [0002] Taking the existing centralized silver dollar anti-counterfeiting technology as an example, many centralized anti-counterfeiting traceability systems now have the following main solutions for anti-counterfeiting: [0003] 1. The appraisal company appraises the silver dollar, first numbers the silver dollar, and gives the appraisal opinion at the same time; [0004] 2.
