摘要

在这项工作中，我们提出了使用一个复杂的哈达玛变换算法的数字水印的卫生系统图像。我们可以利用新引入的算法检测水印中的未经授权访问和攻击。根据重构图像的均方误差和信噪比，给出了几种攻击对测试医学图像的实验结果。

Algorithms for Digital Watermarking of the Health System Images with Hadamard Transform

In this work we have presented using a complex hadamard transform an algorithm for digital watermarking of health system images. We are able to detection the unauthorized access and attacks in the watermarking with the help of the newly introduced algorithms. The experimental results of the some attacks over the test medical images are drawn made on the base of mean-squared error and signal to noise ratio of the reconstructed images.
