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
