Medical confidentiality is an essential duty in the medical profession. In this paper, we introduce a novel robust blind watermarking method for securing the medical report in a DICOM (Digital Imaging and Communications in Medicine) imaging. The insertion of each bit is done in the subtraction of adjacent DC coefficients of the FFT (fast Fourier transformation) using a key k _w . Each bit of the watermark is eXORed with a bit generated by a proposed system which generates a bit sequence in function of the key k _w . The proposed method has the features of having better security, invisibility, and robustness. Experimental results show that it is robust to single, double, and triple attacks and that it has better robustness than recently proposed watermarking schemes.

用于隐藏医疗报告的 DICOM 成像水印

医疗保密是医疗行业的一项基本职责。在本文中，我们介绍了一种新颖的鲁棒盲水印方法，用于保护 DICOM（医学数字成像和通信）成像中的医学报告。每个位的插入是在使用密钥 k _w 的 FFT（快速傅立叶变换）的相邻 DC 系数相减中完成的 。水印的每一位与由建议的系统生成的位进行异或运算，该系统根据密钥 k _w 生成位序列 . 所提出的方法具有更好的安全性、不可见性和鲁棒性的特点。实验结果表明，它对单、双和三攻击具有鲁棒性，并且比最近提出的水印方案具有更好的鲁棒性。
