A blind watermarking method on the basis of Singular Value Decomposition is proposed in this paper. Each bit of a watermark is being enclosed in 4x4 blocks. The method modifies the both left and right orthonormal matrices in order to embed a bit. A new embedding rule with adjustable parameters has been proposed for watermarking. The modification of orthonormal matrices is accomplished according to Van Elfrinkhof’s rotational model. Distortions of watermark embedding are minimized. A criterion of watermarking performance has been proposed that combines robustness and transparency. An adaptation on the basis of the criterion has been employed. Popular attacks have been applied and experimental results have been represented. The proposed watermarking method demonstrates better robustness toward some attacks in comparison with other known blind watermarking methods.
