摘　　要：数字水印是解决多媒体数据版权保护问题的有效手段之一 .分析了一般水印方案应该具备的条件 ,结合传统加密技术、扩频通信技术与图像处理技术提出一种新颖的图像水印方案 .对水印图像进行失真压缩及低通滤波等处理时 ,该方案产生的水印具有稳健性 ,可以直接推广到其他媒体数据上 .仿真结果证明了这种水印的有效性及稳健性 .Digital watermarking techniques have been proposed as an effective solution to protecting the copyright of multimedia data. In this paper, the constraints that a watermarking scheme should satisfy are analyzed, and in the light of the technique of traditional encryption, spread spectrum communication and digital image processing, we present a novel image watermarking scheme. Such watermarks show low pass characteristics and, subsequently, are robust to lossy compression and low pass filtering. Moreover, it can be straightforward used for other media data. Finally, experimental results are reported proving the robustness of the proposed method against some of the most common image processing techniques.
