Abstract. This paper presents two main results. The first is a new ap-
proach to steganography in which data is encoded in correlations among
the pixels in an image. Almost all previous steganographic methods en-
code data in correlations between the pixels and a known external refer-
ence signal. This method hints at the existence of public key watermark-
ing techniques, which will be defined.
The other result is a method for greatly increasing the capacity of a
printed steganographic channel. Because it is specific to printed images,
this method is useful for steganographic problems such as stealth barcod-
