The image watermark scheme based on Scale Invariant Feature Transform(SIFT) feature is proposed for resisting geometric attacks.The feature points are used to construct the Delaunay triangular mask,which can make the triangle to against geometric attacks based on the SIFT point’s ability of resisting geometric attacks.Watermark according the several-for-one principle is embedded in the image content using additive method.Experiments demonstrate that the algorithm can well withstand geometric attacks and usu...
