摘要
随着因特网的迅猛发展和数字记录存储设备的普及,对于声像数据进行加密、认证和版权保护的需求也日益增多,本文综合介绍三维数字水印技术,论述了三维数字水印技术目前的发展现状,明确了现有三维数字水印技术的分类,分析几种典型的三维数字水印的算法,并提出相应的攻击分析,最后介绍了今后的三维数字水印发展方向以及研究前景。
With the rapid growth of the Intemet and the widespread use of digital record devices, there is an increasing demand in the encryption, certification and copyright protection of sound and image. The article gives an overview of 3D digital watermark and the current development status, and provides with a clear classification of this watermark, analysis of several corresponding typical watermarking algorithms, and the relevant attack analysis. At last it describes the future direction and research prospects of development of 3D digital watermark.
