Abstract :
We present a watermarking scheme for digital videos that are based on human visual system characteristics. Our watermarking scheme inserts 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.
