Analysis of Information Protection Based on Quantum Image Steganography

Abstract

This paper analyzes the principal models of quantum image representation – Qubit Lattice, FRQI, Real Ket, and NEQR and identifies their advantages and drawbacks in the context of data-hiding algorithm implementation. A novel approach is proposed to enhance the efficiency of steganographic systems based on quantum image processing. Special attention is devoted to steganographic algorithms employing the Least Significant Bit (LSB) technique in both simple and block-based forms, as well as their robustness, capacity, and imperceptibility. It has been established that quantum implementations of such algorithms increase the level of confidentiality and reduce the probability of hiddenmessage detection.
