In this study, we examine the influence of attack parameters of the StirMark3.1 on the picture quality defined by MOS (Mean Opinion Score), and also show the relationship between the MOS and the PSNR (Peak Signal to Noise Ratio), when seven kinds of parameters are changed independently. From experimental results, it is found that the degradation caused by the attack of pixel moving is difficult to find, if the SNR is greater than 15dB. This means that the watermark should be strong against the pixel moving by the attacking parameters "b", "i", and "o" of the StirMark3.1.
