SVD-Based Watermarking Scheme for Medical Image Authentication

In the current pandemic COVID-19 situation, many patient records are exposed without their knowledge, so, a novel technique is needed to protect the authenticity of patient information by incorporating a new watermark to the medical images. So checking the authenticity of any digital copy becomes very much important aspects of digital communications. In this proposed work, a novel SVD based watermarking method has been introduced for medical image authentication in various medical applications. This method examined against various types of threads and attacks. The results, show that the proposed scheme achieved 73.36 dB PSNR and SSIM is near about 0.99 with 64,980 bit embedding capacity. Compared to the traditional methods, proposed method effectively increases the accuracy of tamper localization as well as PSNR value of the self-recovered image are both significantly increased.
