1. A method of decoding of steganographic data, the method comprising: processing, using a processor, a media signal to extract message values of the steganographic data, wherein the steganographic data is embedded in the media signal by imperceptibly adjusting data values in the media signal; assigning confidence values to the message values based in signal statistics by which the values are determined; and decoding a corrected message from the message values weighted by the assigned confidence values.
