Object based self-embedding watermarking for video authentication

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.
