中文摘要：

提出了将虹膜特征识别与数字水印相结合的数字图像内容版权认证系统。其基本思想是先对虹膜图像进行预处理，直接选取感兴趣区域灰度图像而不是经信息压缩的特征代码作为水印信息；然后在原始图像一维倒谱域嵌入水印图像；最后通过计算频带受限的相位相关（Band-limited Phase-Only Correlation，BLPOC）函数实现虹膜图像认证。实验结果表明该认证算法在保持水印不可感知的同时具有较高的稳健性。

英文摘要：

An efficient scheme is proposed for protecting the ownership of the digital image content by combined the iris recognition with digital watermarking technique. The main ideal is as follows. Iris image preprocessing is conducted firstly, and instead of the feature codes achieved by information compressing, an iris region of interesting at gray level is selected directly as the watermark. Then the watermark image is imbedded into the 1D cepstrum domain of the host image. Iris image authentication is achieved by computing the Band-limited Phase-Only Correlation （BLPOC） functions. Computer simulation results show that the proposed algorithm is of imperceptibility and is robust to most watermarking attacks.
