ABSTRACT:
The present invention generally relates to processing audio, video and images. One claim recites a method including: obtaining media signal comprising a steganographic signal hidden therein; utilizing a programmed electronic processor, selecting portions of the media signal for steganographic signal detection, wherein the subset of the media signal is selected based on at least one or more predetermined probability factors, in which a probability factor comprises a selection criteria or rule to identify portions of the media signal which have a higher likelihood of including a steganographic signal relative to other portions of the media signal; and utilizing a programmed electronic processor, analyzing selected portions of the media signal to obtain the steganographic signal. Of course, other claims and combinations are provided as well.
