Abstract :
In this paper, we propose a robust watermarking algorithm for medical image authentication and protection. The scheme obtains the visual feature vectors of the medical image using DWT-DCT. The watermarking image is encrypted by Logistic Map to strengthen its security. By combining the zero-watermarking concept, we can make the watermarked image robust to common and geometric attacks. Simulation results showed the proposed algorithm has good invisibility and robustness.
