A Survey of Digital Video Watermarking Schemes

Digital watermarking is a technique or act of hiding a secret information (text, signature, logo, audio, image etc.) in the form of a watermark into a digital multimedia such as text, image, audio and video. There are two classes of watermark; visible and invisible. Visible watermark is viewable by the human eye or detectable by human ear while invisible watermark is only detectable with special software, it cannot be seen by human eye or inaudible and it is more robust than the visible watermark Digital video watermarking is a recent technology and has become an area of concern because most reported copyright violation and distribution transpires in video media content. However, researchers have come up with several techniques in trying to tackle these challenges. A review of the prevailing digital video watermarking techniques is presented in this paper.
