Robust Blind Watermarking against Geometrical Attacks with Medical Images for EMR/EHR

In this paper, an efficient solution for robust watermarking against geometrical attacks with medical images is proposed. In the embedding process, at first, we select the robust non-overlapping Scale-Invariant Feature Transform regions. Then, we embed the same information into these regions by using the even-odd quantization technique. In the extraction process, blind recovery of information is p...
