AN EFFICIENT WATERMARKING FRAMEWORK OF AVI VIDEOS USING DCT TECHNIQUE

Abstract

Digital watermarking is a data hiding technique where an information or message is hidden inside a signal
transparent to the user. Video Watermarking is one of the interesting fields to develop a system with authentication and
copyright protection methodology embedded within an efficient video codec. Thus, this technique can be used for copyright
protection, piracy tracing, content authentication, advertisement surveillance, error resilience, and so forth. In this paper, we
give an overview on video watermarking technology, including its properties, applications, performance requirements,
typical algorithms, and comparison among them. As the advanced mixed media are coordinated by means of the system,
expansive measure of information is exchange effortlessly and winding up quicker, less demanding, and require less effort to
make precise. This advance will profit sight and sound item proprietors as deals will increment. The significant hindrance is
the absence of compelling licensed innovation insurance of advanced media to put off unapproved duplicating and
appropriation. In this paper we propose Digital video watermarking plot in light of discrete cosine change additionally the
Design of this plan utilizing Matlab 2014a. Watermarking procedure has been proposed as a strategy to shroud mystery data
into the signs to demoralize illicit duplicating or then again validate the wellspring of the media.
