Abstract—This paper proposed an adaptive multi-ary steganographic method based on additive noise to ensure the security of secret information. In order to minimizing the distortion caused by embedding operations, the characteristics of multi-ary steganography by adding removable noise and multi-ary matrix embedding are analyzed, and then a combination-based coding method is proposed for embedding information by adding the fewest noises. It directly establishes a map between the vector of the secret information and the cover elements with minimum weight. According to the length of the secret information and the estimated embedding capacity, the steganography adaptively divides the secret information and the cover elements into blocks to make full use of the combination-based coding method. The experimental results show that the proposed steganography method obtains higher embedding efficiency and better ability of resisting statistical steganalysis attacks than the general method.
