ABSTRACT:
Aspects of the present disclosure relate generally to methods and systems for signal hiding using feature modulation. One claim recites a method comprising: obtaining data representing a media signal; analyzing the data to determine features of the media signal; using a programmed electronic processor, modifying determined features to hide a signal in the data; and modifying the data to include a characteristic to facilitate later detection of the signal. In some case the features may include statistical features of the media signal. Of course, other claims and combinations are provided too.
