基于Matlab的快速数字水印生成技术

Faster Watermarking Technology Based on Matlab

数字水印作为信息隐藏的一种有效手段，在多媒体数据版权保护方面起着越来越重要的作用。但是由于数字水印 技术涉及到的知识比较广而深，水印的嵌入、提取编程难度较大。本文从数字水印技术本身的特点、一般模型和典型算法出发， 介绍了一种可以快速上手的高效的实用语言--Matlab。并给出一个用 Matlab 工具在静止图像上嵌入水印的实例。

Digital watermarking is a method of information hiding,which plays an important role in protecting copyright of multimedia. But digital watermarking is very hard to learn and to embed a watermark into an image. This paper introduces characteristics, priple, model of watermark. At the same time, some classical arithmetics are expatiated in it. At last, this paper introduces Matlab programe language which used to embed digital watermark in image very fast.
