An Adaptive Image Steganography Based on Depth-Varying Embedding

Steganographic technique is a means of covert communication. In this paper, an adaptive image steganography with high capacity and good security is proposed. Based on local complexity of a cover image, varying-depth embedding is used to improve the imperceptibility and decrease distortions in it. Experimental results show that the steganographic technique may provide higher capacity and be resistant to several well-known steganalytic methods.
