Color two-dimensional code anti-counterfeiting method based on support vector machine

Abstract

The invention discloses a color two-dimensional code anti-counterfeiting method based on a support vector machine, and the method comprises the steps: firstly generating a color two-dimensional code containing a watermark, then collecting a color two-dimensional code image through employing an APP application program, carrying out the preprocessing, extracting texture and color combination features through employing a gray-gradient co-occurrence matrix method and a color space conversion method, finally, training the image data by using a support vector machine (SVM) algorithm to establish a model, and distinguishing the image data of the test set. The designed two-dimensional code anti-counterfeiting system can better distinguish the printed image and the copied image of the color two-dimensional code, and solves the anti-counterfeiting problem of the current two-dimensional code.

Description

technical field [0001] The invention relates to the technical field of intelligent image processing, in particular to an anti-counterfeiting method of a color two-dimensional code based on a support vector machine. Background technique [0002] With the development of the Internet and information technology and the popularity of smart phones, two-dimensional codes are widely used in payment, anti-counterfeiting, industrial control and product traceability due to their advantages of large capacity, strong error correction ability, easy identification and strong reliability. field has been widely applied. However, the two-dimensional code itself does not have a strict anti-counterfeiting function, because its data conversion and encoding are open, which limits the application of the two-dimensional code in areas with high anti-counterfeiting requirements or special anti-counterfeiting requirements; The code can be easily copied and transferred arbitrarily by means of image co...

Problems solved by technology

However, the two-dimensional code itself does not have a strict anti-counterfeiting function, because its data conversion and encoding are open, which limits the application of the two-dimensional code in areas with high anti-counterfeiting requirements or special anti-counterfeiting requirements; The code can be easily copied and transferred arbitrarily by means of image collection, printing or copying, which makes the two-dimensional code itself does not have the function of preventing forgery and copying

For example, when a two-dimensional code appears in the field of commodity circulation in the form of a label as an information carrier, if it is maliciously copied by criminals and transferred to counterfeit and shoddy products for sale, it will not only disrupt market norms, but also cause confusion in normal commodity circulation. And seriously damage the interests of consumers
