Video watermarking based on multi-dimensional scaling and singular value decomposition

Concerning the intellectual property rights of video on Internet,a new digital video watermarking method based on Multi-Dimensional Scaling (MDS) and Singular Value Decomposition (SVD) was proposed.First,the frames were mapped to points in the 2D space using MDS,and then the watermarks were embedded into the differences between the frames of video and their images under the mapping through SVD.The experimental results show that the proposed method has very strong robustness against spatial desynchronization attacks such as rotating,scaling and clipping.Furthermore,it also achieves high robustness against noise and median filtering.In addition,the method can resist temporal desynchronization such as frame dropping and insertion to some extent.
