主　　题：Steganography Distortion function Runlength Complexity 

摘      要：This paper presents a novel adaptive JPEG steganographic scheme in Discrete cosine transform(DCT)domain using Run-length statistical complexity(RSC). Unlike the traditional complexity measurements, RSC considers the change randomness of DCT coefficients in image blocks. The distortion functions in both side-informed and non-side-informed schemes are derived by RSC and minimized by Syndrome trellis coding(STC). Experimental results show superior performance of our scheme over a wide range of embedding rates at different image quality factors compared with previous three common steganographic schemes.
