In this paper a new steganographic method is presented with minimum distortion, and better resistance against steganalysis. There are two ways to control detectability of stego message: one is less distortion, and another is less modification. Concerning the less distortion, this paper focuses on DCT rounding error, and optimizes the rounding error in a very easy way, resulting stego image has less distortion than other existing methods. The proposed method compared with other existing popular steganographic algorithms, and the proposed method achieved better performance. This paper considered the DCT rounding error for lower distortion with possibly higher embedding capacity.
