Abstract: Video watermarking is an important issue to encrypt intellectual property information for the data creators. Increasing data exchange over the internet also enhancing the probability of piracy and attacks on the encrypted/watermarked video. This problem is encouraging the research community to work over the robust watermarking algorithm which provides ideally attack free watermarked video with the quality maintenance of the video. The Video watermarking techniques using Discrete Wavelet Transform (DWT) or Principal Component Analysis (PCA) played a vital role to develop enhanced algorithm to develop the digital watermarking techniques since the last decade. In this paper, a rigorous literature survey has been done to understand the new possible trends in digital watermarking. An investigation of DWT, PCA, and other possible techniques has been done. The possible attacks also discussed along with a survey to understand the robustness of the proposed algorithm of watermarking. This study and survey provide a better way to understand the new areas and scope of research to the researchers.
