For the problem of Robust or need much information for realizing Robust of video watermarking scheme,the scheme is proposed that realizes the semi- blind robust video watermarking with video patch,KAZE feature matching and DCT transform.Firstly,user register their information and make an unique key for each one,with the unique key randomly produce the unique frame-patch and save the frame-patch to database. Secondly,frame and frame-patch do KAZE feature matching and detect the embedded region. Lastly,frame patch and the distorted video do KAZE feature matching and extract the watermarking. Experimental results show that the proposed method is robust,synchronization of extraction watermark process and fix the problem of digital property dispute and illegal user tracing
