DWT and IDWT Using Secret Key and Watermarking with in Video Compression
Abstract
In this paper, Authenticating
watermarking is nothing but inserting a hidden
object in order to detect deceitful alteration by
hackers. The object may be in terms of a secret
key or password etc. There are quite few
numbers of authentication methods are
available for videos. Resent developers in
digital video and internet technology helps the
common user to easily produce illegal copies
of videos. In order to solve the copyright
protection problem and deceitful alteration by
hackers of videos, several watermarking
schemes have been widely used. Very few
authenticating of watermarking schemes have
been produced for defining the copyrights of
digital video. The process of Digital
watermark embeds the data called watermark
in digital media like image, video, audio file
etc. so that it can be claimed for rights. The
paper represents the complete software
implementation of 3-Level DWT algorithms
and to have more secure data a secret key is
used. The secret key is given to watermark
image during embedding process and while
extracting the watermark image the same
secret key is used. To check effectiveness of
the watermark video MSE and PSNR
parameters are used.
