基于图像的数字水印攻击技术分析
随着因特网的日益普及,多媒体信息交流达到了前所未有的深度和广度,但作品侵权随之也更加容易,篡改也更加方便.因此,如何保护作品版权已受到人们的高度重 视.为了揭示现行数字水印技术在稳健性方面的一些不足,笔者对几类攻击技术进行论述,分析了DCT（离散余弦变换域）数字水印及人眼视觉感知系统.并基于DCT域数字水印进行水印嵌入、水印提取,从而对此进行包括噪声攻击测试、JPEG压缩攻击测试、高斯低通滤波攻击测试等方式的实验,根据实验结果分析DCT域数字水印对于各种攻击下的鲁棒性,并获得较好的效果.

摘要要翻译成Abstract哦
Image-based Analysis of Digital Watermarking Attacks
With the increasing popularity of Internet, multimedia information exchange to an unprecedented depth and breadth, but also easier to work along infringement, tampering and more convenient. Therefore, how to protect copyright in the work has been people's attention. In order to reveal the existing digital watermarking technology in the stability of the number of deficiencies, the author discusses several types of attack techniques to analyze the DCT (discrete cosine transform) digital watermarking and human visual perception system. Digital watermarking based on DCT domain watermark embedding, watermark extraction, which carried out this attack, including noise testing, JPEG compression attack test, Gaussian low pass filtering attacks testing method of experiment, analysis of the experimental results for a variety of DCT domain watermarking robustness under attack, and get good results.
Key words: digital watermarking; watermark attacks; DCT domain; robustness; MATLAB
