In this paper, a pristine method of tough digital video watermarking algorithm in H.264 compressed domain is articulated. Most of the video watermarking techniques interleave the watermark in I-frames but in this paper a fabulous method of blind low complexity video watermarking in P-frames for H.264 video is proposed. Our algorithm decides which 4×4 block within the macro-block of P-frame will be set in based on the covert key. The proposed method restricts embedding by selecting only the nonzero quantized AC-residuals of P-frames, thus escalating the watermark robustness. Simulation outcome illustrate that there is decrease in bit rate and at the same time it is robust to quite a few diverse attacks.
