This paper gives an overview of cryptographically strong mass application invisibility in digital communication. It summarizes principles and methodology, clarifies terminology, and defines some new concepts. A new algorithm for hiding bit selection in digital images is proposed and an experimental implementation of the algorithm is described. Finally, the paper closes with a discussion of the implications of the availability of invisible communication.
