Abstract(in English) A new watermarking method for color video using a nonlinear digital filter to consider the robustness to both the geometry transform attack and the time-domain low-pass filtering attack is proposed. This method is based on Haitsma and Zhao's methods which embed water mark signals into the luminance mean series. The operation of the screen mean value doesn't receive the influence by a geometrical transformation of the screen. We showed that it is more effective to embed into color difference signal instead of the luminance and to use a nonlinear digital filter in the detecting process. But this method was not robust enough to the attack of time domain filtering. In this paper, we newly improve this method by replacing the watermark signal with a low frequency signal and detecting it using the nonlinear digital filter. Computer simulations verify its performance.
