subject

description

International audience; In order to contribute to the security, transmission and sharing of medical data between hospital centers, we propose a watermarking scheme for hiding medical information, specific to the patient, in the host image. In this regard, the watermark consists of inserting data (usually binary data) in media (image in our case) and try to find these data with maximum fidelity, after applying various attacks. The principal goal of our proposal is the conservation of psychovisual quality of the image, on the one hand, and the extraction of the different data inserted in another side The robustness of the proposed scheme is tested against various attacks such as JPEG compression, adding noise, and filtering.
