摘要：How to solve watermarked products against geometrical attacks is the key problem to improve watermark robustness. So this paper proposed a digital watermarking embedding algorithm using discrete wavelet transformation (DWT) based on Singular value decomposition (SVD). Simulation experiment shows that the algorithm can well withstand such geometrical attacks as rotation, scaling, cropping and translation. And it also has good imperceptibility, high security and big watermark capacity. ©2010 IEEE.
