LSB数字水印技术 数字水印（Digital WATERmarking）技术是将一些标识信息(即数字水印)直接嵌入数字载体当中(包括多媒体、文档、软件等)或是间接表示(修改特定区域的结构)，且不影响原载体的使用价值，也不容易被探知和再次修改。但可以被生产方识别和辨认。通过这些隐藏在载体中的信息，可以达到确认内容创建者、购买者、传送隐秘信息或者判断载体是否被篡改等目的。数字水印是信息隐藏技术的一个重要研究方向。 数字水印是实现版权保护的有效办法，是信息隐藏技术研究领域的重要分支。作为一种新型的有效的版权保护手段，数字水印技术倍受人们的关注。数字水印主要是通过在原始资料中嵌入秘密信息——水印,来证实资料的所有权。

This discussion will attempt to outline some truths and common misconceptions about digital audio WATERmarking. It will survey the intrinsic obstacles that such technology is required to overcome, shedding light on its performance criteria, compromises and limitations. While doing so, it will also survey a few common types of applications, hopefully leading to a clear understanding as to the appropriateness of such technology and its expertise within multimedia content protection.

During the past four years, most of our research activities have been focused on image but also video and 3-D objects processing for security applications (WATERmarking and biometrics) and communications (talking heads, interfaces), with a special emphasis on facial images. More about our work can be found at http://www.eurecom.fr/~image. Our research activities are conducted with the backing of several industrials, in particular France Telecom Research and STMicroelectronics. For the past few years, we have had a regular scientific collaboration on Fractal Image Coding, WATERmarking and Biometrics with the University of California, Santa Barbara (UCSB), in particular with Prof. K.
