| 摘 要： | 针对计算机网络不断发展中多媒体版权难以保护问题,研究了基于DCT域图像水印算法,分析了该算法的特点,提出了基于DCT域的图像数字水印方案。该方案将水印嵌入到DCT域感觉容量最重要的系数DC分量上。实验结果验证了该算法的有效性、可靠性、抗攻击性、鲁棒性和不可见性,能够为媒体信息在防伪、防篡改、认证、保障数据安全和完整性等方面提供有效的技术保障。

| Abstract: | With the continuous development of computer networks,it is more difficult to protect multimedia copyright.In view of the problem,the digital watermarking algorithm based on DCT was studied and analyzed.An image digital watermarking scheme based on DCT algorithm was put forward.In the scheme,water mark was embedded in the DC components which have the largest perceptual capacity.The results showed that the watermarking images according to DCT are of validity,dependability,robustness,and invisibility.It can pr... |
