Abstract. We use concepts from communication theory to character-
ize information hiding schemes: the amount of information that can be
hidden, its perceptibility, and its robustness to removal can be modeled
using the quantities channel capacity, signal-to-noise ratio, and jamming
margin. We then introduce new information hiding schemes whose pa-
rameters can easily be adjusted to trade off capacity, imperceptibility,
and robustness as required in the application. The theory indicates the
most aggressive feasible parameter settings. We also introduce a tech-
