Data hiding in halftone images with authentication ability using three-level noise-balanced error diffusion
Keyword(s):
A novel data hiding method in halftone images with authentication ability was proposed in this paper. A secret image and an authentication image were simultaneously encoded into two halftone images. The secret image was visually reconstructed by stacking the two halftone images together. To verify the validity of the secret, one halftone image was shifted down for several units and stacked with the other one to reveal the authentication image. Experimental results were provided, demonstrating that the proposed method is effective and outperforms existing methods.
