Agricultural product two-dimensional code anti-counterfeiting inspection method based on watermark library

Abstract

The invention belongs to the field of information identification, and particularly relates to an agricultural product two-dimensional code anti-counterfeiting inspection method based on a watermark library. The method comprises the steps of establishing a two-dimensional code library containing watermarks, tracing a two-dimensional code watermark image, and verifying the two-dimensional code watermark image; the establishment of the watermark-containing two-dimensional code library comprising a two-dimensional code generation module and a watermark library; combing the two-dimensional code generation module with the watermark library to generate a two-dimensional code with a watermark; establishing the two-dimensional code with the watermark into a two-dimensional code library with the watermark; the watermark-containing two-dimensional code library being used for verifying the two-dimensional code watermark image; wherein the two-dimensional code watermark image is obtained by tracinga two-dimensional code containing a watermark through two-dimensional code watermark image tracing. According to the agricultural product two-dimensional code anti-counterfeiting inspection method based on the watermark library, the image watermark library is designed, watermark embedding is not single any more, even if an attacker cracks one bar code, the attacker has little influence on a wholetwo-dimensional code watermark system, and the reliability of the system is further improved.

Description

technical field [0001] The invention belongs to the field of information identification, and in particular relates to an anti-counterfeiting inspection method for two-dimensional codes of agricultural products based on a watermark library. Background technique [0002] Digital watermarking technology seeks to meet the constraints of robustness, imperceptibility, security and reliability, etc. optimal design. At present, the most extensive two-dimensional code anti-counterfeiting method is mainly to form a corresponding traceability code through certain coding rules. The traceability code is similar to the ID code of a product. Each product has its unique traceability code. The rules are uniformly coded. This unique code corresponds to the QR code of the product packaging. Therefore, the QR codes of all products are unique. The combination of traceability codes and product information is used for anti-counterfeiting of QR codes. Only the combination of unique identificatio...

Problems solved by technology

Therefore, the QR codes of all products are unique. The combination of traceability codes and product information is used for anti-counterfeiting of QR codes. Only the combination of unique identification traceability codes and product information for QR code anti-counterfeiting cannot meet the requirements of two-dimensional codes. code anti-counterfeiting requirements
