English Abstract

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 thesis aims to produce a.

robust 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 cod i rig, standard.

Digital image is used to be embedded in MPEG-1 video coding standard, by pars in £ video and extracting Intra-frame which are compressed independently by using DCT transform, then third degree B-splint-curve equation will be Implemented on I-frames macro blocks data to interpolate data and provide according to the comparing condition an effective points that represent the selected Location where watermark image will be embedded.

Then B-spline curve fitting equation will be used to show distribution of watermark location through secondary intra-frame of MPEG-1 standard by drawing curves depending on watermarked points as control points.

Watermarking extraction algorithm will be implemented to get watermark image from watermarked video by using the effect point algorithm to find location where watermark being added, then extraction algorithm will be implemented.

Test measurements will be used to prove robustness of proposed technique against watermark attacks and control point for curve drawing illustrating how watermark image is distributed among number of video samples.
