Data embedding is one of the important issues for securely conveying secrets from senders to receivers without arousing any notices to attackers. Wet paper coding (WPC) is one of the data embedding schemes which embeds secrets into a subset of pixels of an image. The pixels in the subset are also called dry pixels. Inspired by wet paper coding, a novel data embedding scheme with a magic matrix is...
This paper presents a reversible data embedding scheme with prediction and dissimilar techniques for palette-based images. Two embedding rules are imported in the proposed method, and no extra bit map is required to indicate which rules are applied in which pixels to embed secrets. As the experimental results show, when the hiding capacity is 255 Kb, the visual quality of the decoded image for our...
