Product anti-counterfeiting method and system based on electronic tag

Abstract

The invention discloses a product anti-counterfeiting system and a product anti-counterfeiting method based on an electronic tag. The system comprises the electronic tag disposed on an anti-counterfeiting object and a verifying device. The system is characterized in that the electronic tag at least comprises a cipher processing unit which can carry out asymmetric cryptographic operation, and a memory module in which electronic tag identification information, an electronic tag authentication code, product information and a product authentication code are stored; the electronic tag holds at least one public key / private key cipher pair; and the verifying device verifies authenticity of the electronic tag through a challenge / response protocol based on an asymmetric cipher technology. The purpose of the invention is to provide an anti-counterfeiting method and an anti-counterfeiting system which enable manufacturers and consumers to verify product authenticity through communicating with the electronic tag disposed on the product.

Description

technical field [0001] The invention belongs to the technical field of article anti-counterfeiting, and in particular relates to an article anti-counterfeiting method and an anti-counterfeiting system using an electronic tag with a password processing unit. Background technique [0002] Counterfeit goods are a common social problem with great harm. Counterfeit goods lead to the proliferation of low-quality goods, which damages the economic interests of manufacturers, has a bad impact on commodity brands, and also damages the interests of consumers. Counterfeit medicines and counterfeit food even endanger the health of consumers. Counterfeit product packaging is often similar or identical to the genuine product, making it difficult for consumers to identify it. Although some manufacturers only sell their products in specialty stores, manufacturers cannot guarantee that specialty stores or salespersons will not participate in the sale of counterfeit products. Therefore, soc...

Problems solved by technology

This method has an important flaw: counterfeiters can easily copy the content of the label and produce a label with the same content

Using asymmetric cryptography in challenge / response mode, counterfeiters cannot generate a correct response to the challenge unless they know the password inside the tag

Because the challenge is different each time, reusing previous responses cannot pass validation
