In 2010, Chen et al. proposed a data hiding scheme with high payload and good visual quality. The edge information is detected and most of the secret bits are embedded into the edge area. An index pixel is chosen to record the edge information for each block. However, the embedding space will decrease because of the index pixel. Thus, we proposed a data hiding that enhances the visual quality based...
In this paper, a novel data hiding method employing reduplicating embedding is proposed. This method uses seven most significant bits to embed two secret digits and sets the least significant bit as an indicator. Therefore, two secret digits can be embedded into one pixel-group without using the original cover-image and extra data. Because of repeating to embed secret data, our method can provide...
