Embodiment Construction

[0029] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0030] Such as figure 1 As shown, a product anti-counterfeiting method based on the material marking block chain of this embodiment, the premise is that the block chain is a special distributed database, it is a point-to-point transaction, the entire network is composed of many points, and the data Stored at various points, it is a network without a center. When building a product verification system, it is necessary to build a blockchain network to attribute different users to different nodes.

[0031] The anti-counterfeiting method comprises the steps of:

[0032] Product material marking: chemical marking of the product; the specific process is: after the production of the product is completed, the key parts of the product are chemically marked, and the product can be uniquely represented by usi...

Abstract

The invention discloses an anti-counterfeiting method for products based on a material marking block chain. The method comprises the following steps of product material marking, marking information and product information chaining, two-dimensional code generation, chained information query and offline inspection. The invention discloses an anti-counterfeiting system for the anti-counterfeiting method for products based on the material marking block chain. The anti-counterfeiting system comprises a material marking module of a product, an upper chain module of marking information and product information, a generation module of a two-dimensional code, a query module of on-chain information and an off-line inspection module. The problem of authenticity of off-chain products is solved throughthe material marking technology; the authenticity of the information on the upload chain is ensured by using a block chain technology. Two-dimensional code technology is utilized to solve the problemthat information on a chain and information off the chain are not interconnected, and firm connection is established between a product off the chain and the information on the chain.

Description

technical field [0001] The invention relates to the technical field of product verification, in particular to a product anti-counterfeiting method and system based on a material marking block chain. Background technique [0002] As an emerging technology, blockchain is increasingly used in real life due to its traceability and tamper-proof features. How to prevent product counterfeiting has been a hot topic for a long time. Finding an effective way to prevent product counterfeiting is of great significance to the development of enterprises. [0003] Traditional product verification is centered on the manufacturing enterprise for product verification. However, it lacks third-party supervision and the center is paralyzed, which will lead to the collapse of the entire system. The entire system crashed, causing a lot of damage. In some enterprises, the two-dimensional code provider not only manufactures two-dimensional codes but also forges two-dimensional codes, which reduces...
