In the watermarking algorithm of the medical image, the principal problems faced are how to determine the region of interest (ROI) and improve the hiding capacity. This paper proposes a robust multiple watermarks algorithm for the medical image based on DWT and DCT, which can effectively solve the referred problems. The algorithm combines the visual feature vector of images, encryption technology with the third party authentication, and avoids the tedious process for selecting ROI. This… CONTINUE READING
