    In this paper, we present a steganographic method that improves image quality after existing data hiding methods. This method works in compressed domain (JPEG) of image. In several previous methods, they usually change coefficients to hide information. And some methods tried to enhance the embedding performance of general steganographic method like F5 including Matrix Encoding [1,5-7,9,11]. We have been analyzed the effect of quantization table during data hiding on compressed domain. Finally, we considered that there would be more chance to reduce the distortion from steganographic method. As the result, this paper provides little bit more improved result in view of image quality. This result can give some contribution for future steganographic methods which will work in compressed domain like JPEG
