Noiseless Steganography

This volume introduces Nostega—a novel noiseless steganography paradigm. Rather than hiding data in noise or producing noise, Nostega camouflages messages as well as their transmission in the form of unquestionable data in the generated steganographic cover. The book explains how to use Nostega to determine suitable domains capable of generating unsuspicious steganographic cover in which messages are embedded in the form of innocent data compatible with the chosen domain. It presents a number of Nostega-based methodologies and discusses their implementation and steganalysis validation.
