Abstract
In this paper we describe a process whereby the magnitude of either one or two frequency components of a signal is modified in order that it may be used to encode a hidden message within a signal in such a way as the casual observer would have no way of noticing the presence of a hidden message. Previous work has used filtering and signal addition to achieve the same goals. The current work improves on this by using a recent super-resolution component-identification technique to isolate the components to modify, limiting the impact on the quality of the signal.
