一种基于相息图的彩色水印的制备方法

Color watermark preparation method based on kinoform

Abstract

The invention discloses a color watermark preparation method based on kinoform. In the method, kinoform is applied in color watermark technology; compared with conventional color watermark technology, no reference light is led in during reproduction of kinoform, so that a single reproduction image can be acquired during reproduction; a random phase secret key is added, so that safety of watermark information is improved; due to own characteristics of kinoform, both robustness and safety can reach high level.
本发明公开了一种基于相息图的彩色水印的制备方法,该方法将相息图应用到彩色水印技术中,相比于传统的彩色水印技术,由于相息图再现时没有引入参考光,再现时能够得到单一的再现图像,且本发明加入了随机相位密钥,提高了水印信息的安全性,同时又由于相息图自身的特点,在鲁棒性和安全性上均能达到较优水平。
