IMITATIONAL SOFTWARE PACKAGE FOR RESEARCHING HIGHLY DETECTABLE STEGOSYSTEMS — HUGO SYSTEMS

This article describes a simulation software designed to conduct research on highly undetectable
stegosystems (so-called HUGO systems), the purpose of which is to increase the efficiency
of the stegosystem with respect to the undetectability of hidden messages, provided they
are transmitted in communication channels with a high noise level. To achieve this goal, this paper
solves the problem of developing a software package that performs on the sender’s side discrete
chaotic transformation of a secret message, then embedding it into a covering object using the
±1HUGO method and encoding, and on the recipient’s side decoding using a multi-threshold decoder,
extracting a secret message and reverse discrete chaotic transformation. In addition, the
software package must calculate performance indicators: the peak signal-to-noise ratio and the
Pearson correlation coefficient of the covering object and the stego
