摘要
数字水印是通过把特定的秘密信息以不可感知的形式嵌入到图像、文本、语音、视频等各种数字媒体中来确认版权所有者,以达到版权保护的目的.一个有效的水印系统必须具备较强的鲁棒性、安全性和透明性.文章介绍了图像处理的基本方法,根据小波理论提出了一种基于KENT的映射置乱小波域盲水印算法.
Digital watermark technology is a new technology that can imbed unsensibly the secret information into picture, text, sound, and video to confirm the copyright owner and achieve copyright protection. An effective watermark system must possess stronger robustness, security and transparency. This text introduces the basic ways of processing images. According to small wave theory, a messy light wave blind watermark algorithm is proposed on the basis of KENT.
