A Salient Region Watermarking Scheme for Digital Mammogram Authentication

Abstract— A region of interest (ROI) based fragile watermarking scheme for digital mammogram authentication is presented in this paper. Here, we propose a new mammogram segmentation scheme for the automatic definition of the ROI for a given mammogram. Difference Expansion based embedding techniques have been used to provide authentication features for the given mammogram. Furthermore, we have implemented the proposed watermarking scheme in both MATLAB and C. Through exploiting the inherent parallelism in the low level image processing layer, we have ported the scheme onto the CUDA platform to further accelerate the real time performance of the proposed scheme. Experimental results and discussions are presented towards the end of this paper.

Index Terms— CUDA, digital mammogram authentication, fragile watermarking, ROI segmentation.
