AbstractAs the computers are more and more integrated via the network, the
distribution of digital media is becoming faster, easier, and requiring less effort to
make exact copies. One of the major impediments is the lack of effective
intellectual property protection of digital media to discourage unauthorized
copying and distribution.
This paper aims to produce random and dynamic watermarking technique to
provide copyright protection for digital media (video) by embedding a digital
image for video sequences compressed according to the MPEG-1 video coding
Digital image is used to be embedded in one of the most widespread video coding
standard (MPEG-1), by implementing third degree B-spline curve equation on Iframes
macroblocks data to interpolate data and provide according to the
comparing condition effective points that represent the selected location where
watermark image will be embedded.
Using B-spline curve fitting equation will show distribution of watermark location
through secondary intra-frame of MPEG-1 standard by drawing curves depending
on watermarked points as control points.
Test measurements will be used to prove robustness of the proposed technique
against watermark attacks and control point for curve drawing illustrating how
watermark image is distributed among a number of video samples.
