Abstract :
We present a watermarking scheme for digital videos that are based on the human visual system characteristics. Our watermarking scheme inserts a perceptually invisible watermark in the discrete cosine transform (DCT) domain. We have shown that the proposed scheme provides better results than two other popular schemes both in transparency and robustness
