摘要
数字水印是一种新的有效的数字产品版权保护和数据安全维护的技术,它是一种十分贴近实际应用的信息隐藏技术,近年来已成为国内外的研究热点并有着广泛的应用前景。首先介绍数字水印技术的特点、分类及应用领域,并阐述了其基本原理,同时对一些鲁棒彩色图像数字水印算法做了概要性的介绍。由于彩色是我们平时接触最多的,因此,彩色图像的水印算法比灰度图像水印算法更具实用性。最后,指出了彩色图像数字水印今后的研究方向和前景展望。
Digital watermarking, the new and effective technology for protecting digital product and safeguarding the safety of data. It is a technology for reserving information, which is very next to the actual application. It is a topic that has recently gained increasing attention all over the world. The characteristics, classification and applications of watermark techniques are first introduced, and the basic concepts. At the same time , introducing the robust color image digital watermarking. Because the color image is the most we touch in peacetime, so the color image watermark is more utility than the gray image. Finally, the possible research direction of color image digital watermark technology and perspective are pointed out.
