Dual watermarking for video using discrete cosine transform

Abstract

Digital watermarking technique is becoming popular for copyright information. The watermark embedded in the digital video may be incorrectly detected and extracted due to lack of appropriate algorithm, so the main concern is to implement the algorithm which is more resistant to different types of attacks. We proposed a video watermark technique has been introduced where Pseudo Random Sequence for Frame Section and Discrete cosine Transform fusion Technique, for adding more security, is used. PSNR, MSE and NC values are analyzed on the basis of different noises and attacks. Hybrid technique is robust against high stream, low stream, frame drop, frame trim attacks. Software used MATLAB
