    Region-Based Medical Image Watermarking Approach For Secure EPR Transmission Applied to e-Health
    (Springer, 2024) Benyoucef, Aicha; Hamaouche, M’Hamed
    Digital health services have been more popular recently since it is simple to share electronic medical information via an open network. Several researchers have been interested in the problem of guaranteeing the confidentiality of these important records; they developed different methods of embedding this secret information in the shared medical image by watermarking techniques. One of the essential electronic patient records not being focused on in the security is the medical imaging test report (MITR), which is the radiologist’s interpretation and analysis of the medical images acquired during the examination. So the proposed approach is a region-based medical image watermarking for secure patient MITR. It is a new method based on embedding a QR code image of this MITR in the region of non-interest of the medical image in the frequency domain by applying the discrete wavelet transform and singular value decomposition techniques. The evaluation of the results of the proposed method using the following parameters PSNR (55.2132 dB), SSIM (0.9976), and NC (0.9999) is observed. It achieves high payload capacity, authentication, imperceptibility, and security against different attacks.
