Abstract：
: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 kw. 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 kw. 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. Graphical abstract The proposed security system.
