A blockchain-based packaging material verification method, device and system

Abstract

The invention discloses a block chain-based packaging material verification method, device and system. The method includes: reading the anti-counterfeit traceability label attached to the packaging material to obtain the unique identification code of the anti-counterfeit traceability label. Among them, the anti-counterfeiting traceability label is provided with an identification area for reading a unique identification code and a feature area for users to input user characteristics. Query the corresponding block in the blockchain network according to the unique identification code. According to the block information of the queried block, the anti-counterfeit traceability information of the packaging material corresponding to the anti-counterfeit traceability label is obtained. Among them, the anti-counterfeit traceability information includes the user characteristic information uploaded by the service node in the previous circulation process of the packaging material. Obtain the current user characteristics of the characteristic area on the anti-counterfeit traceability label, and match the current user characteristics with the user characteristic information in the block information to verify the authenticity of the packaging materials. The invention ensures that the packaging will not be counterfeited and improves the user's trust in the brand.

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. Products without anti-counterfeit labels, or anti-counterfeit labels that are easy to copy will lead to rampant counterfeit and shoddy products in the market, damage to the reputation of counterfeit brands, resulting in a decline in product sales and huge economic losses. Smart packaging in a broad sense means that in a package, a product or a combination of a product and a package, there is an integrated component or an inherent feature, through which a smart product compounding specific requirements is endowed wit...

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
