Digital video is one of the popular multimedia for exchanging data over internet. Due to their perfectly replicable nature many unauthorized copies of the original video can be reproduce. Therefore, methods are required to protect copyrights of the authorized owner and prevent illegal piracy. In this paper, a robust Discrete Wavelet Transform (DWT)-based blind digital video watermarking scheme with scrambled watermarks based on scene changes has been proposed for authentication of digital video, which embeds different parts of a single watermark into different scenes of a video. The watermarking algorithm is very powerful against the attacks of frame dropping, averaging and compression, which are some of the common types of attacks applied particularly on the video and due by the use of DWT it can also withstand geometrical attacks making the watermark perceptually invisible. The proposed algorithm has been compared with an existing DWT based watermarking scheme and is found to exhibit better robustness.

The watermarking scheme takes the major advantages in resisting the attacks and partial removal of the watermark. The results also show that the scheme is robust against different image processing attacks like addition of noise, median filtering and cropping. The approach cultivates an innovative idea of embedding different bits of a watermark in the frames of video and its advantages were clearly seen from the experimental results. The security for the confidential videos of company or defence department is very much important. This system can provide more security to the video. We can restrict piracy and unauthorized downloading of video
