Abstract:
1. A method of decoding of steganographic data from an electronic media signal, the steganographic data being embedded in the electronic media signal by imperceptibly adjusting data values in the media signal to create a steganographically embedded signal, the method comprising: with a programmed electronic processor, processing the electronic media signal to produce data values from the media signal that have been adjusted to embed message signals conveying the steganographic data; with a programmed electronic processor, processing the data values to detect the message signals embedded in the electronic media signal; with a programmed electronic processor, assigning confidence values to the message signals based on confidence that detection of the message signals are correct to produce message signals with corresponding confidence values; with a programmed electronic processor, analyzing the message signals and associated confidence values to confirm detection of a correct message in the media signal.
