Dynamical running coding was previously proposed as a method for construction of steganographic schemes in digital steganography. In this article, a new approach of fast coding is proposed to improve steganographic efficiency. Original 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 method. Therefore, the complexity of the proposed method is less than the original method. Meanwhile, 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.
