摘要
提出一种基于小波变换域的公钥数字图像水印系统,两个密钥对应两个有意义的二值图像水印,公钥对应可公开的版权,私钥对应版权所有者。实验结果表明系统有较强的鲁棒性,能有效抵御数字图像攻击。
Proposes a public key image watermarking system based on wavelet transform, two key two meaningful corresponding binary image watermark, a public key corresponding to disclose copyright, rights holders corresponding private key. The experimental results show that system can resist digital image attacks efficiently.
