Abstract
In the field of health, the messages conveyed by images have a considerable impact on the life of patients. In
order to facilitate decision support on medical imaging, we will present in this paper the method of digital
image watermarking based on the Harris principle whose objective is to hide the data in a medical image in
order to evaluate its robustness. In addition, it ensures that the patient's image is authentic for a better
diagnosis. To carry out this work we decided to start on the basis of two principles namely those of Moravec
and Harris to obtain a solution that meets the need for digital watermarking. They consist in taking a random
image (medical or not) and extract these points of interest and we obtain a mark, then take the original image
of the patient that we add to the mark to obtain a digital image watermark. This watermark is invisible since
all the invisibility properties are respected.
