摘要：
Blind watermarking techniques that need no original information during watermark detection are more desirable than informed ones for practical usage and convenience in watermark extraction. In this paper, a blind MPEG-2 watermarking technique which is robust against arbitrary ratio scaling is described. It can be directly applied in other block-DCT based video compression techniques. The main advantage of the scheme is its simplicity, blindness and adjustable watermark payload by trading-off with imperceptibility and robustness. Since the watermark extraction is based on self numerical references within frames of watermarked video, synchronization between the original and watermarked video is not necessary for detection.
