Abstract

The invention relates to an anti-copying coded image. The anti-copying coded image comprises a coded image body arranged on a base image of printed matter, and a digital watermark added to the coded image body. Coding information of the printed matter is contained in the coded image, and a semi-fragile digital watermark technology is adopted for the digital watermark. The invention further provides an anti-copying coded image system and application of the anti-copying coded image system. Through the anti-copying coded image, the anti-copying coded image system and the application, not only can the channel conflict prevention function and the source tracing function of printed matter be achieved, but also the anti-fake function of the printed matter can be achieved.

Description

technical field [0001] The invention relates to the field of image coding, in particular to an anti-duplication encoded image based on digital watermark technology and encoding technology, an anti-duplication encoded image system and its application. Background technique [0002] Because two-dimensional codes and color codes can store more information in a small plane, and the information in two-dimensional codes and color codes can be quickly read by using mobile phones, scanners and other equipment, therefore, existing products are usually Use labels such as QR codes and color codes to mark product information. However, with the rapid development of science and technology, it is very easy to counterfeit goods and these labels on goods, which makes it more and more difficult for consumers to distinguish the authenticity of goods, which brings great inconvenience to consumers and also causes great harm to the market. a lot of trouble. Therefore, researching a coded image...
