According to the security of video watermarking,a video watermarking scheme based on dual watermark encryption and SVD is proposed. Firstly, scrambling the watermark image, after the scrambling watermark through Chebyshev chaotic mapping is encrypted, guarantee the security of the watermark; then, the video key frames conduct three wavelet transform, Using SVD invariance of geometric distortion, the watermark is embedded into LL3, HL3 and LH3, 3 times. Experimental results show that the algorithm has good robustness to noise attack 、MPEG compression and shear.
