Commodity anti-counterfeit code generation and verification method

Abstract

The invention discloses a commodity anti-counterfeit code generation and verification method. According to the generation of a commodity anti-counterfeit code, a production center generates a 0-level plaintext A according to the basic information of a product, wherein the basic information of the product contains an enterprise code A1 and a sequence code A2; the production center obtains an enterprise key K1 corresponding to the enterprise code according to the enterprise code A1 and encrypts the sequence code plaintext A2 according to the enterprise key K1 so as to obtain an encrypted ciphertext B1; the ciphertext B1 and the plaintext A1 constitute a 1-level ciphertext B; the production center encrypts the 1-level ciphertext B according to a production key K2 so as to obtain a 2-level ciphertext C, and then carries out confused encryption so as to generate a ciphertext D, wherein D is composed of D1, D2 and D3; and D is encrypted by a website key K3, so that an anti-counterfeit code E can be obtained. The anti-counterfeit code obtained by using the method of the invention can satisfy uniqueness, confidentiality and irregularity and can help a consumer to verify the authenticity of a commodity and all characteristic information related to the commodity such as a factory release date, a production place and a warranty period.

Description

technical field [0001] The invention relates to a method for generating and verifying a commodity anti-counterfeiting code, which belongs to the technical field of commodity anti-counterfeiting. Background technique [0002] With the development of society and economy, people's demand for materials has increased, and people's attention to product quality has become a topic that cannot be avoided in this society. Counterfeit goods not only violate the rights and interests of consumers, but also bring harm to commodity producers. In order to protect their products from unscrupulous merchants, various production enterprises began to pay more and more attention to the anti-counterfeiting problem of products. However, the anti-counterfeiting code generated by traditional anti-counterfeiting technology has low technical content and simple decryption process. , can no longer meet the needs of this digital society. Contents of the invention [0003] The technical problem to be so...
