In this paper, we propose a novel image steganography technique with an adaptive embedding scheme that combines the methods of edge detection and hybrid Hamming codes to conceal a secret message in a cover image. We use the Canny edge detection algorithm to identify the sharpness degree of a block because the human visual system is more sensitive to the smooth regions than the sharp regions in the...
Data hiding is a technique that embeds a cluster of secret messages into the original image. The image with secret messages can be distributed on the Internet while the message embedded would not be easily discovered by a third party. In this way, the secret message can be well protected. At the same time, an image might be made with complex and smooth textures. If changes are made on complex textures,...
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...
