%X Geometric attacks are difficult to resist for watermarking algorithms.Although most existing geometric-resisted algorithms can resist some kinds of geometric attacks，however，their robustness to common image processing is week.A watermarking algorithm which is both strongly robust to geometric attacks and common image processing is proposed in this paper.Watermarking messages combined a Gaussian-noise template are embedded to vertical high frequency coefficients which are produced by one-level integer wavelet transform of the host image.Then the same messages are embedded to each sub-image by quantization repeatedly.Two watermarking images are extracted by correlation calculation and majority rule.Finally，the ultimate watermarking is decided by a judge rule.Experiment results show the algorithm is both robust to geometric attacks and common image processing，meanwhile，the imperceptibility of the algorithm can meet the request.
