A hybrid digital watermarking system for video authentication includes an
authenticated acquisition subsystem for digitally watermarking video data
and a video management subsystem in signal communication with the
authenticated acquisition subsystem for verifying the digitally
watermarked video data, where the authenticated acquisition subsystem may
include a watermarking device for applying each of an identity signature
and a control signature to the video data within a hybrid digital
watermark, and the hybrid digital watermark may achieve progressively
varying robustness by means of error-correcting signature coding and/or
rate-distortion guided bit embedding.
