AI Technical Summary

Technical Problem

Existing anti-counterfeiting methods are easily imitated and copied, failing to effectively protect the authenticity of goods and brand reputation. Single digital code anti-counterfeiting methods are also susceptible to being cracked.

Method used

The non-periodic color graphic anti-counterfeiting coding method is adopted. By collecting product information and standardizing it into 14-digit decimal numbers, 64-bit binary numbers are randomly generated. DES encryption and P2-type Penrose mosaic patterns are used to generate basic grid patterns, which are then combined with a visual anti-counterfeiting layer for verification.

Benefits of technology

It improves the security and anti-counterfeiting performance of product information, realizes the comprehensiveness and reliability of multiple anti-counterfeiting measures, and enhances the authenticity of products and brand reputation through the infinite diversity and complex geometric aesthetics of anti-counterfeiting codes.

Abstract

The application provides a non-periodic color pattern anti-fake coding method applied to commodity outer packaging and belongs to the technical field of commodity anti-fake, which forms a pattern of 65 adjacent lattices randomly selected from a P2 Penrose tessellation pattern and a pre-set digital string matrix position processing package identity information, obtains data in different forms meeting commodity package identity identification but containing complete information, generates multiple sets of different geometric pattern, and sprays the pattern on the commodity outer packaging as the unique identity of the package. The application adopts multiple sets of random codes containing complete information which are updated irregularly. On one hand, the method gives the packaged commodity a unique ID and improves the coding capacity; on the other hand, in the case that the information part is damaged, destroyed or tampered, the coding and decoding recovery rate of the original code under different damage conditions is improved, which is beneficial to the anti-fake and tracing of commodities.
