空格编码数字水印算法研究

Research of Digital Watermarking Algorithm Base on Space Encoding

数字水印是一种将特殊信息嵌入媒体数据的关键技术,近年来已成为国内外研究的热点并有着广阔的发展前景。在介绍文本数字水印通用模型的基础上,对空格编码文本数字水印算法进行研究,该算法属于脆弱型水印,拥有良好的安全性能和较高的水印容量,具有一定的实用价值。

Digital watermark is a key technology which put special information into media data. In recent years it has become the popular topic, and it holds wide application prospect in several domains. Base on the introducing the common module of document digital watermarking, this paper researches the document watermarking algorithm base on space encoding. This algorithm is a kind of fragile watermarking, and it has a high value with good security performance and better capacity of watermarking.
