Problems solved by technology

However, this simple combined application not only loses the brightness of the hologram but also destroys the aesthetics, and the interference of the holographic diffraction light when extracting the watermark information also increases the misjudgment rate and response time

Abstract

The present invention discloses a method for generating an anti-counterfeiting label containing watermark information. The method comprises the steps of (S100) embedding watermark information in a watermark region of an original image and generating a watermark image containing the watermark information, (S200) processing the watermark image and converting watermark image into holographic plate-making data, (S300) forming a hologram on a photoresist plate according to the holographic plate-making data, (S400) using an electroforming mode to form a holographic molded plate containing the hologram on a metallic nickel plate, and (S500) transferring the hologram to a moldable material through the holographic molded plate to create the anti-counterfeiting label. According to the method, the watermark information is embedded into the original image and the watermark information is presented through the diffraction of a holographic microstructure to make the anti-counterfeiting label, the perfect fusion of the digital watermarking technology and the holographic technology is realized, the brightness and the aesthetics of the hologram can be kept, at the same time, the interference and misjudgment rate in identifying and extracting the watermark information of a hologram are reduced, and the response time is greatly reduced.

Description

technical field [0001] The invention relates to the field of laser holographic anti-counterfeit technology, in particular to a method for generating an anti-counterfeit label containing watermark information and the anti-counterfeit label. Background technique [0002] Laser holographic anti-counterfeiting technology is a kind of visual graphic information produced on products by using laser rainbow hologram plate making technology and molded replication technology. With the comprehensive utilization of computer dot matrix lithography technology, 3D true color holographic technology, multiple and dynamic imaging technology and other technologies, the development of a higher level of laser holographic anti-counterfeiting technology has been promoted. Encryption technologies such as optical random interference fringe, optical miniaturization, dynamic holography, spatial stereo, and digital dot matrix images developed by using the above-mentioned technologies continue to emerge...
