Video cameras have been widely installed in public facilities for the surveillance applications. So, video authentication has become more and more important. This paper presents an object based self-embedding watermarking for video authentication. The principal content of entire video and details of moving objects are protected by a reference sharing mechanism. At the receiver, if the stego-video is authenticated as un-tampered, the details of moving objects can be restored completely. If the stego-video is judged as tampered and the tampered area is not too extensive, the principal content of tampered regions and details of moving objects can be restored.
