Based on the observation that low-frequency DCT coefficients of an image are less affected by geometric processings, we propose a new blind MPEG-2 video watermarking algorithm robust to camcorder recording. The mean of the low-frequency DCT coefficients of the video is temporally modulated according to the information bits. To avoid watermark’s drift into other frames, we embed watermarks only in the B-frames of MPEG-2 videos, which also allows minimal partial decoding and achieves efficiency… CONTINUE READING
