In the present scenario there is a requirement to merge watermarking with cryptography for better authentication and security. The proposed work is carried out based on the above requirement and it is done in two folds. The host video is initially divided into frames then divided into two folds as static frames and dynamic frames. In static frame watermarking process is carried out the watermark logo is embedded in the chosen static frames using Haar discrete wavelet transform and in dynamic frame Elgamal encryption process is used for security purpose. The frames were joined to obtain the embedded video, the frames were subjected to various attacks the PSNR and Correlation coefficient factor is obtained for analyzing the quality of the video.
