摘要

介绍了两种典型的数字水印算法,并用MATLAB进行了仿真。针对它们的优缺点,通过对结果的分析,提出了基于离散余弦变换和离散小波变换的数字水印算法。分析了多重数字水印在数字版权保护中的应用及盗版跟踪问题。利用Visual c++实现数字图像版权保护系统,包括水印的嵌入和提取。

Research and Implementation on Digital Image Copyright Protection System
Two typical digital watermark algorithms were introduced in this paper, and did the simulation using MATLAB. In view of their advantages and disadvantages through analysis of the results, propose the digital watermarking algorithm based on discrete cosine transform and discrete wavelet transform. Analyze the application of the multiple digital watermarking in digital copyright protection and the pirate tracing problem. Use the Visual C++ to achieve the digital image copyright protection system both including the watermark embedding and extracting.
