The application relates to the field of information security and anti-counterfeiting technology and discloses a two-dimensional code anti-counterfeiting intelligent verification system which comprises a code assignment management module, a physical fingerprint registration module and an offline verification module. The code assignment management module is used for generating a two-dimensional code load containing a digital signature and a product serial number and transmitting the two-dimensional code load to a printing device to execute a printing instruction. The physical fingerprint registration module collects a microtexture feature vector of a two-dimensional code area during the execution of the printing instruction and binds the microtexture feature vector with the product serial number to generate a preset fingerprint template. The offline verification module is used for acquiring a real-time microtexture and performing feature alignment by referring to the preset fingerprint template. The physical fingerprint registration and feature alignment verification scheme is adopted, the printing microtexture is extracted as a unique identifier, the double binding of the digital signature and the physical feature is realized, the effect of distinguishing the original and the copied copy is achieved, and the problem that the existing static graphics are easily cloned by high-precision photographing or copying is solved.

The invention relates to the technical field of information, and particularly discloses a two-dimensional code verification management system and method. The two-dimensional code verification management method comprises the following steps: step 1, classifying input information into a fixed value and a change value; 2, determining input information, converting the input information into a corresponding code, and determining a product code; 3, converting the product code into a two-dimensional code, and associating the two-dimensional code with the product; counting the number of times of converting the product code into the two-dimensional code, and reporting an error when the number of times is greater than 1; and 4, when the number of the products with the same fixed value is larger than 1, from the second product, the step 2 to the step 3 are repeated, and when the step 2 is repeated, only the change value in the fixed values is determined again until the fixed values of the products change. According to the two-dimensional code verification management system and method, the problem of repeated tagging is solved.
