The single watermark algorithms always merely have single function. In order to overcome the drawback, this paper proposed a dual video watermarking scheme based on transform domain. To implement the video copyright and integrality authentication, this paper embedded robust watermarking and fragile watermark. At the same time, this scheme made good use of the wavelet transform to embed the two different kinds of watermarking in the same video respectively. The fragile watermarking is to serve the robust watermarking. Experiments demonstrate this scheme can not only protect the copyright of the video effectively, but also protect against some attacks, such as shearing attack, JPEG lossy compression attack, noise attack etc. This scheme has better robustness and invisibility.
