Anti-counterfeiting authentication method of anti-counterfeiting image of printed matter based on digital watermarking technology

The invention relates to an anti-counterfeiting authentication method of an anti-counterfeiting image of printed matter based on a digital watermarking technology. Most of encryption technologies and digital watermarking technologies only provide an anti-counterfeiting function for the digital field of an image and can not resist geometric attacks and attacks similar to printing, scanning, and the like. The method comprises the following steps of: firstly, processing a two-value bar code, and embedding the two-value bar code into a carrier image; then, printing once to form authorized printedmatter; taking a picture of the printed matter by using a mobile phone, uploading the picture to an authentication center, and reading the watermark by using a detection algorithm to identify the authenticity of the printed matter so as to achieve the anti-counterfeiting purpose. Because the watermark embedded in the printed matter is invisible, the watermark has good invisibility and safety. Theinvention realizes the detection by using the mobile phone and has the advantages of equipment convenience, mobility, broad application prospect, and the like.
