  Robust Color Image Watermarking using Biometric Protection and Image Authentication Key

  By B. P. Mishra, H. N. Pratihari, P. Das

  Abstract: In recent days, it becomes difficult to provide protection to color images which were captured by modern capturing devices. This paper presents a novel work on copyright protection by providing authentication process for extraction of watermark of color still images. New blind frequency domain non-correlation based watermarking algorithm using one dimensional Walsh coding technique is introduced to improve the robustness. The developed algorithms do not required the original image for …
