Quantum steganography for secure data transmission

Quantum steganography is an advanced method of hiding information within quantum systems, leveraging the unique properties of quantum mechanics-such as superposition, entanglement, and the no-cloning theorem-to achieve unbreakable secrecy. Quantum steganography provides perfect secrecy against both classical and quantum hacking, making it a cutting-edge technology in cybersecurity. This paper introduces a quantum steganography technique that builds on the advantages of of Novel Enhanced Quantum Representation (NEQR) of digital imaging and integrates quantum-resistant solutions for secure (biometric) transmission, anti-spoofing, and privacy-preserving authentication. Our analysis and experiments have shown that our approach is robust against several types of attacks, and offers protection against both current and future threats while maintaining the steganographic property of imperceptibility and capacity, making it one of the best options for secret information transmission.
