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.
Keywords: Feature Points,
Delaunay Tesselation, RGB colour image, Turbo code, Robustness,
Fidelity, collaboration, awareness.
