A packaging material verification method, device and system based on a block chain

Abstract

The invention discloses a packaging material verification method, device and system based on a block chain, and the method comprises the steps: reading an anti-counterfeiting traceability label pastedon a packaging material, so as to obtain a unique identification code of the anti-counterfeiting traceability label, Wherein the anti-counterfeiting traceability label is provided with an identification area for reading the unique identification code and a feature area for a user to input the features of the user; And querying a corresponding block in the block chain network according to the unique identification code; And according to the queried block information of the block, obtaining anti-counterfeiting traceability information of the packaging material corresponding to the anti-counterfeiting traceability label, Wherein the anti-counterfeiting traceability information comprises user characteristic information uploaded by service nodes in a previous circulation process of the packaging material; And obtaining the current user characteristics of the characteristic region on the anti-counterfeiting traceability label, and matching the current user characteristics with the user characteristic information in the block information to verify the authenticity of the packaging material. According to the invention, the package is ensured not to be counterfeited and the trust degree ofusers to brands is improved.

Description

technical field [0001] The present invention relates to the field of information management, in particular to a blockchain-based verification method, device and system for packaging materials. Background technique [0002] The role of anti-counterfeiting traceability is to enhance product reputation and protect brand interests. The traceability function makes users more at ease, and has a deeper understanding of the product, enhancing trust in the product brand.

Problems solved by technology

[0003] At present, one type of traditional packaging does not have the function of anti-counterfeiting and traceability. Users cannot know the production and distribution of products after purchasing, which makes users have certain doubts about product quality. The growth of brand trust requires a lot of time to accumulate

The other type has anti-counterfeiting means, but due to limitations in cost and technology, it may be easily cracked and counterfeited, resulting in a flood of counterfeit goods, or the threshold is too high and requires professional equipment, which cannot be identified by users themselves. attraction
