Abstract: This paper presents a robust watermarking scheme of medical information security and terminal mobile phone adaptation for PocketNeuro project. The later term refers to a project created for the service of neurological diseases. It consists of transmitting information about patients « Desk of Patients » to a doctor’s mobile phone when he is visiting or examining his patient. Our scheme provides image robustness for both image Gray-level transformation and scaling to adapt them to the doctor’s mobile phone. Experiments carried out on a database of 20- 256× 256 pixel-sized medical images show that our watermarking scheme is robust to both scaling and Gray-level transformations. For the purpose of increasing the image watermarking robustness against attacks of an image transmission and to perform a large number of bits to hide into images, we encode with turbo code image-embedded information. Results demonstrate that fidelity can also be improved by this image watermarking scheme.
