Embodiment Construction

[0014] refer to figure 1 As shown, an anti-counterfeiting method based on digital signature and public key system is provided:

[0015] Principle: Commodity producers use their own private key to encrypt the digital signature of each unique feature of the product to be sold, generate corresponding ciphertext and bind it to the product; consumers use the public key disclosed by the commodity producer to Decrypt the ciphertext bound with the commodity to be purchased and verify whether the digital signature of its unique feature matches, thereby helping consumers to judge the authenticity of the commodity.

[0016] The method consists of three parts:

[0017] The production part, the production part is mainly completed by the commodity producer, which generates a key pair and performs authentication. The commodity producer generates a set of public key pairs by itself, the private key is used to encrypt its own product data, and the public key is provided to the encrypted The ...

Abstract

The invention discloses a product anti-counterfeiting method based on digital signature and public key system, wherein a medium with a unique surface feature code is bound to each product to be sold; the feature code of the medium cannot be duplicated; the characteristic package of each product to be sold is scanned and imaged to generate pictures, extract corresponding feature code according to a certain algorithm, and generate signature data, commodity HASH value for short; the commodity HASH value of each product to be sold, together with the product name, the producer name, the production time, the quality guarantee period, and the like, is encrypted by using the private key, and the commodity HASH value corresponding to each product to be sold is marked on the commodity; the signature ciphertext corresponding to each product to be sold is marked on the commodity or the commodity package; and the code of the unique producer is marked on the commodity. The counterfeiting method has low production cost and high anti-counterfeiting property, and is convenient to use and is not easy to clone and counterfeit.

Description

technical field [0001] The invention relates to the anti-counterfeiting technology of commodities, in particular to a product anti-counterfeiting method based on a digital signature and public key system, and also relates to a verification method for anti-counterfeiting products using the method. Background technique [0002] In the prior art, in order to prevent commodities from being counterfeited, the product must be subjected to anti-counterfeiting treatment and verified to confirm whether the product is genuine or not. The disadvantages of the old anti-counterfeiting method: the old anti-counterfeiting method has the disadvantage of high cost, or there are The disadvantage of low anti-counterfeiting performance, or the disadvantage of inconvenient use, or the disadvantage of being easily cloned. Contents of the invention [0003] The object of the present invention is to, aim at the above-mentioned defect of existing anti-counterfeiting technology, provide a kind of p...
