主　　题：cover object fast coding secret message steganography 

摘      要：Dynamical running coding was previously proposed as a method for construction of steganographic schemes in digital *** this article,a new approach of fast coding is proposed to improve steganographic *** embedding method is discussed in two cases of constructing different generating matrix;however,the proposed method generalizes the problem to only one case by changing the construction method from the original ***,the complexity of the proposed method is less than the original ***,both theoretical analysis and experiment results show better performance in terms of distortions and alterations of the cover objects when embedding the same amount of information data bits,which proves a better resistance against steganalysis.
