“…For example, if a binary visual pattern is embedded, then it may be visually recognized from as low as 70% of its bits. 8,38 But if sensitive data is embedded, such as names, ID numbers or URLs, then nothing less than CDR = 100% may be acceptable. We also note that error correction coding (ECC) techniques may be used to ensure perfect data recovery from the prints at the expense of reducing the amount of embedded actual useful data.…”

Abstract. In this article, we propose a joint halftoning and data hiding technique for color images. To ensure high quality of the printed image, the color direct binary search (CDBS) iterative halftoning algorithm is used. The proposed approach uses the commonly available cyan, magenta and yellow colorants to hide data in the chrominance channels. Orientation modulation is used for data embedding during the iterative CDBS halftoning stage. The detector is using PCA-learned components to extract the embedded data from the scanned image. Experimental results show that this proposed CDBS-based data hiding method offers both higher data hiding capacity and higher robustness to the print-and-scan channel when compared to the state-of-the-art grayscale counterpart method. The relatively high correct detection rate make this approach suitable for applications which require exact extraction of embedded data in prints.

“…Recently, many watermarking schemes [1,4,7,8] have been proposed to embed a watermark into binary images for image authentication with small distortion. If the image was modified, the recovery operation was used to reconstruct the modified regions.…”

“…Lee et al's scheme also reduced the high pixel-flipping rate. Guo et al [4] then presented a parity-matched error diffusion watermarking scheme, based on a block-wised, majority voting strategy for image authentication. To increase the security, this scheme spread the watermark bit to each pixel of the cover image block.…”

Data hiding is a technique by which secret data can be delivered securely by embedding it into a cover multimedia document. In this paper, a high capacity data hiding scheme based on block classification is proposed for binary images. In the proposed scheme, the block classification process determines complex regions in the image used for embedding secret data. For each block in the complex region of the image, some secret bits are embedded by lightly modifying few pixels to minimize an embedding distortion. On the receiver side, the secret bits can be then extracted without requiring the original image. Experimental results demonstrated that the proposed scheme obtained a high embedding capacity while maintaining a low distortion. In addition, when compared with previous schemes for binary images, the proposed scheme improved the embedding capacity significantly with the same level of embedding distortion.
