Low-complexity video watermarking scheme resisting geometric distortions

A low-complexity video watermarking scheme against geometric distortions is proposed for DCT-encoded compressed video data. The full DCT coefficients have proven to be invariant to scaling and local geometric attacks. Therefore the watermark is embedded into frames by modifying the low-frequency full DCT coefficients. To meet the requirement of real time performance, a fast inter-transformation is employed to construct full DCTs directly from block DCTs. The experimental results show that the proposed scheme is transparent and robust to signal processing attacks, lots of geometric distortions and frame dropping.
