In this paper, we describe a configurable content-based MPEG video authentication scheme, which is robust to typical video transcoding approaches, namely frame resizing, frame dropping and requantization. By exploiting the synergy between cryptographic signature, forward error correction (FEC) and digital watermarking, the generated content-based message authentication code (MAC or keyed crypto hash) is embedded back into the video to reduce the transmission cost. The proposed scheme is secure… CONTINUE READING
