Abstract
The disclosure relates to data hiding and digital watermarking in imagery. One claim recites an apparatus comprising: memory storing an image editing program; an input for receiving imagery, the imagery comprising image features that vary across the imagery; a processor configured for: encoding a pattern of 2-dimensional auxiliary data at a first intensity within a first multi-dimensional region within the imagery; and encoding the pattern of 2-dimensional auxiliary data at a second, different intensity within a second multi-dimensional region within the imagery. Of course, other claims and combinations are provided.
