Summary:In this paper, the steganographic method proposed by Chang and Tseng (C.C. Chang et al., 2004) is reviewed and the problem related to the Chang-Tseng scheme is described. A modified scheme is proposed to overcome the problem in which the embedded data cannot be extracted correctly. Moreover, in order to enhance the image quality of the stego-image and enlarge the embedding capacity of the host-image, a novel method to embed secret data into the host-image by adaptive LSB substitution based on the pixel-value differencing is proposed. Experimental results show that both of the embedding capacity and the image quality of the stego-image outperforms than the Chang-Tseng scheme. In addition, the embedded confidential information can be obtained properly from the stego-image without the assistance of the host-image
