针对可逆水印安全性问题，提出一套高容量低失真的实现方案.通过选择图像的参考子集，利用密钥控制下的自适应插值算法，有效预测参考子集的补集，形成相关性较高的估计图像.估计图像与真实图像的差形成差值图像，此差值图像直方图峰值点可以达到较大高度，通过移位操作能隐藏高容量水印，并保持较低的视觉失真.由于预测算法本身由密钥控制，能满足水印嵌入的Kerckhoffs安全准则，提高安全性能.

We propose a scheme of reversible watermarking with high security, low distortion and large capacity. After setting the reference sets, we use a keyinformationbased adaptive interpolation algorithm to estimate a complementary image. Because the predicted images are close to the desired ones, the difference image has a high peak in the histogram. Histogram shifting is performed to achieve a large payload while keeping low embedding distortion. As the operation is controlled by a key, the method conforms to the Kerckhoffs’ criterion and is therefore secure.
