%X It has been a difficulty and hotspot in steganography research that how to design large payload steganographic algorithm while high-order statistical security is ensured. Based on the Markov Chain security benchmarking and dynamic compensating means, a novel second-order distribution maintained steganographic method was proposed, which preserves the second-order distribution of the cover image and the embedded payload is unreduced. Experimental results showed that the proposed algorithm can maintain the second-order distribution of cover image while larger secret information is embedded, and improve the steganographic security.
