The Research on Watermarking for Mobile Computing
面向移动计算的数字水印技术研究

In the mobile computing environment, we propose a novel watermarking algorithm based on integer wavelet through pixel-wise masking with simple human visual system (HVS).Then the correlation between the watermarking sequence and the marked DWT coefficients coded with difference refinement is discussed. Finally, watermarking detection algorithm is presented for scalable coding.
