A Content-adaptive Image Steganography based on SDCS
The “sum and difference covering set (SDCS) is a steganographic technique which provides high embedding efficiency. In this paper, we implement SDCS in image steganography by searching an appropriate SDCS for high embedding efficiency and low complexity. Thus the contamination in smooth areas of image is evident for steganalyzer, we propose a novel content-adaptive steganographic scheme based on SDCS, in which the hidden data are embedded in noisy areas of cover image evaluated by a noise level sorting. The experimental results show that our scheme enhance the steganographic security compared with some state-of-the-art works, and the high visual quality of stego image is preserved with considerable embedding rate.
