| Abstract: | This study presents a low-complexity watermarking for embedding a watermark into two or more halftone images with dot diffusion. The first halftone image is obtained by traditional dot diffusion, while the others are achieved by applying the proposed secret-shared dot diffusion (SSDDF) technique. The visual decoding pattern can be observed when these similar dot-diffused images are printed on transparencies and then overlaid each other. An improved decoded result can be yielded by computer-aid XNOR operation. The proposed scheme is proved to be superior to the former dot diffusion with nonlinear thresholding (DDNT) proposed by Taheri et al. from the conducted experiments. Moreover, two extensions, namely dual SSDDF (DSSDDF) and adaptive SSDDF (ASSDDF), are also proposed to provide better decoding rates and compromised image quality. © 2010 Wiley Periodicals, Inc.
