Abstract: In this paper, we present a hybrid watermarking scheme for video authentication based on wavelet domain. It embeds one robust watermark for temporal authentication distinguishing different inter-attacks, such as frame loss, inserting and reordering. Other two watermarks are used for intra- authentication, one for discriminating the malicious attacks from acceptable manipulations, and the other for locating malicious attacks. The latter two watermarks are content-based. Zernike Moments Magnitudes (ZMMs) of the lowpass wavelet band of the host video frames are chosen as features. Experimental results show that ZMMs are robust to MPEG-2 compression and slight noise, while fragile to content change. This semi-fragile property is used to tell malicious attacks from non-malicious attacks. We also use structure of the embedded ZMMs to locate the tampered area. Experimental results show that this scheme can authenticate the video effectively.
