In the recent past years the newly emerging trend of 3D movies and projection drawn huge attention of researchers and enterprises, ranging from movie producing companies and entertainment to researchers and program developers, similar to other multimedia files these types of media need to copyrighted, a 3D video required a significant amount of effort to become a tangible product. In this paper we will present a technique to watermark such media for copyright protection purposes for 3D video to achieve both imperceptibility and robustness, using a scene change detection technique to identify the best location (frame) to be impregnated with the watermark. The 3D video file has attributes such as color channel, stereo objects and depth prospective, in this paper we will focus on such features to inject our watermark, and then discuss the impact of such process on the resulting file. From the experimental results we have concluded that our algorithm has proven imperceptibility and robustness.
