摘要：

In this work, we propose a blind watermarking approach for medical image protection. In this approach, the watermark will be constituted of the Electronic Patient Record and the image acquisition data. In order to enhance the security and guarantee the data integrity, the Electronic Patient Record hash will be added to the watermark. The integration process is based on a DWT-SVD combination, a DWT is applied to the retinal image, then, an SVD is applied to the LL sub-band. The watermark will be then integrated into the least significant bits of the S component obtained by combining the parity of the successive coefficients. Experimental results for imperceptibility and robustness show that the proposed scheme maintains a high quality watermarked image and remains highly robust against several conventional attacks.
