In this article, we use the absolute-value-decision policy and effectively promote the SNR performance of the Yang and Wang’s scheme [9]. Besides, there is no need of using extra overhead for the intended receiver. Furthermore, the hidden message can be designed on-demand with various size. Experimental results indicated that the average SNR of the proposed method is larger than that of the Yang and Wang’s scheme about 3.54 dB. The proposed method is also robust against the attacks such as inversion, translation, truncation, and Gaussian noise-addition attacks. Our method is suitable for real-time applications as well.
