The present invention generally relates to digital watermarking and
steganography. In one implementation, a method is provided including acts
of receiving a media signal comprising a steganographic signal
redundantly embedded therein; selecting a subset of the media signal for
steganographic signal detection, wherein the subset of the media signal
is selected based on at least one media signal characteristic associated
with the subset; and detecting a steganographic signal hidden in the
subset of the media signal. In another implementation, a digital
watermark detector is providing including: electronic processing
circuitry; memory; and executable instructions stored in memory for
execution by said electronic processing circuitry. The instructions
comprises instructions to: process a media signal comprising a digital
watermark redundantly embedded therein; select a subset of the media
signal for watermark detection, wherein the subset of the media signal is
selected based on at least one media signal characteristic associated
with the subset; and detect a digital watermark hidden in the subset of
the media signal.
