Made a based on DWT and DCT domain of has meaning II value image digital watermark algorithm using Arnold transform on watermark sequence for reset mess, elimination pixel of space correlation, increased watermark of security and combined Wavelet transform and discrete cosine transform of characteristics, will watermark information embedded to image transform domain of low frequency and if coefficient in the, improve watermark of robustness and not visible sexual experimental proved the algorithm has better of anti-compression, and anti-noise and anti-cut sexual.
