Abstract
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.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
96 words
A method comprising: obtaining a media signal comprising a steganographic signal hidden therein; selecting, using a processor, portions of the media signal for steganographic signal detection, wherein the portions of the media signal are selected based on at least one or more predetermined probability factors, wherein 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 analyzing, using the processor, selected portions of the media signal to obtain the steganographic signal.
Claim 2
Independent Claim
96 words
A method comprising: obtaining a media signal comprising a steganographic signal hidden therein; selecting, using a processor, portions of the media signal for steganographic signal detection, wherein the portions of the media signal are selected based on at least one or more predetermined probability factors, wherein 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 analyzing, using the processor, selected portions of the media signal to obtain the steganographic signal.
Claim 3
Dependent Claim
15 words
The method of claim 1 , wherein the media signal comprises imagery, video, or audio.
Claim 4
Dependent Claim
30 words
The method of claim 1 , wherein at least one probability factor utilizes a host media signal information, wherein the host medical signal information is independent of the steganographic signal.
Claim 5
Dependent Claim
19 words
The method of claim 1 , further comprising inhibiting use of the media signal based on the steganographic signal.
Claim 6
Dependent Claim
21 words
The method of claim 1 , wherein the method is carried out in real time as the media signal is received.
Claim 7
Dependent Claim
35 words
The method of claim 1 , wherein selecting portions of the media signal utilizes selection criteria based at least in part on detecting portions of the media signal with a floating segmentation of the signal.
Claim 8
Dependent Claim
