一种基于图像融合的数字水印方案

数字水印是一种新型的多媒体信息版权保护技术，它是在多媒体信息中嵌入标志版权信息的不可感知且难以去除的水印信息，通过检测水印信息来进行版权保护及盗版跟踪，从而有效地弥补了数字加密技术的不足之处。提出了一种具有良好鲁棒性的数字水印方案。由于该方案利用人眼视觉系统把数字水印嵌入到图像的视觉重要区域中，对水印的破坏将会非常困难。

A scheme of digital watermark based on image fusion

Digital watermark is a new technique to provide copyright protection for intellectual property that is in digital format.Digital watermark works by concealing imperceptible information within the digital data.A scheme of watermark with good robustness is proposed in this paper.Using human vision system,watermark is embeded into the important vision area of the image,therefore it is very difficult to attempt to damage the watermarking.
