Problems solved by technology

However, the existing digital anti-counterfeiting technology basically uses a pseudo-random sequence or an ordered serial number to generate a commodity anti-counterfeiting code through DES symmetric encryption, which has certain differences with the performance requirements of the commodity anti-counterfeiting code "unforgeability and uniqueness" in digital anti-counterfeiting technology. Due to th...

Abstract

The invention discloses a method for generating a commodity anti-counterfeit two-dimensional code, which comprises the following steps: coding commodity identity information to generate a unique commodity identification code; converting the commodity identification code into numerical data and switching data; the initial value, parameters, initial iterative steps and iterative interval steps of the chaotic system are calculated by using commodity identity information and external key respectively, and the chaotic sequence is generated by iterating the Chebyshev chaotic tent map. According to the switching data, a certain operation is selected respectively, and the cipher characters in the corresponding relation table between the user-defined numerical data and the cipher characters are scrambled by using the scrambling rule of the position change before and after the chaotic signal sorting, thereby the commodity anti-counterfeit number is generated, and then the commodity anti-counterfeit two-dimensional code is combined to generate the commodity anti-counterfeit code. The method for generating that commodity anti-counterfeit two-dimensional code provided by the invention is simpleand feasible, has strong safety, is difficult to crack, and the generate commodity anti-counterfeit two-dimensional code has uniqueness and non-forgery.

Description

Technical field [0001] The invention relates to the field of digital anti-counterfeiting technology, in particular to a method for generating anti-counterfeiting two-dimensional codes for commodities. Background technique [0002] In today's society, the counterfeiting of commodities has gradually become a serious problem facing the global economy. The anti-counterfeiting situation in the 21st century is particularly severe. As counterfeiting technology is becoming more sophisticated and counterfeiters are becoming more experienced, the appearance of counterfeit products is also constantly improving. , So there are higher requirements for digital anti-counterfeiting technology. However, the existing digital anti-counterfeiting technology basically uses a pseudo-random sequence or an ordered serial number to generate a product anti-counterfeiting code through DES symmetric encryption, which has certain performance requirements for the "unforgeability and uniqueness" of the product...
