The rapid evaluation of image manipulation and tampering has evoked the need for protecting digital data.Therefore a copyright protection method is used to protect the user information known as watermarking.Watermarking is the major image processing technique used to authenticate digital data.In this paper a hybrid approach is proposed to protect the digital data and also authenticates the user information.The proposed approach is an improvement over traditional video watermarking approaches.It uses fractions from the watermarked image to embed into the unique frames of the original video.The whole approach is divided into three steps which are described in the next sections of this paper.To check the resilience and robustness of this approach, various attacks are implemented over the watermarked video.After attacks, watermark image is extracted from the watermarked video to check the robustness of this approach.The quality of the recovered watermarked image is analysed using bit error rate.Experimental results show that this approach is very robust compared to other approaches.
