多重水印技术综述

当今时代，作为计算机领域的研究热点，数字水印技术得到了广泛的应用。多重水印克服了传统数字水印的不足，将多个水印嵌入到宿主载体中，并且每个水印都有不同的特性，代表不同的信息。本文介绍了多重水印的特征及其分类、多重数字水印技术的基本原理，并对典型的多重水印算法进行了阐述。最后．分析指出了数字水印技术的研究现状与发展前景。

A Survey of Multiple Watermarking

As one of the hot research topics in the area of computer, digital watermarking technology has gained wide applications nowadays. Multiple Watermarking overcomes drawbacks of the single digital watermarking .It embeds multiple watermarks each of into the host, each watermark has different characteristics and represents different information. This paper makes an introduction of the characteristics and classifications of multiple watermarking, makes discussion and analysis of typical algorithm. Finally, it gives the recent research circs and the prospect of the digital multiple watermarking.
