Watermarks technique in mpeg-1video by b-spline

Abstract EN

As 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 standard.

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 macro blocks 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.
