In today’s era of escalating digital threats and the growing need for safeguarding sensitive information, this research strives to advance the field of information concealment by introducing a pioneering steganography methodology. Our approach goes beyond the conventional boundaries of image security by seamlessly integrating classical image processing techniques with the cutting-edge realm of quantum encoding. The foundation of our technique lies in the meticulous identification of distinctive features within the cover image, a crucial step achieved through the utilization of SIFT (Scale-Invariant Feature Transform). These identified key points are further organized into coherent clusters employing the K-means clustering algorithm, forming a structured basis for our covert communication process. The core innovation of this research resides in the transformation of the concealed message into a NEQR (Novel Enhanced Quantum Representation) code, a quantum encoding framework that leverages the power of quantum circuits. This transformative step ensures not only the secrecy but also the integrity of the hidden information, making it highly resistant to even the most sophisticated decryption attempts. The strategic placement of the quantum circuit representing the concealed message at the centroids of the clusters generated by the K-means algorithm conceals it within the cover image seamlessly. This fusion of classical image processing and quantum encoding results in an unprecedented level of security for the embedded information, rendering it virtually impervious to unauthorized access. Empirical findings from extensive experimentation affirm the robustness and efficacy of our proposed strategy.
Modern information security measures have changed as a result of the quick development of quantum computing and communication technologies. As computing power increases, traditional steganography methods are more susceptible to quantum attacks. By using quantum mechanical features like superposition, entanglement, and quantum error-correcting algorithms to safely hide data, quantum steganography shows promise as a solution. Quantum steganography is an advanced cyber security method that offers full secrecy from either classical or quantum hacking. Using quantum-resistant methods for secure (biometric) transmission, anti-spoofing, and privacy-preserving authentication, this work presents a quantum steganography technique that expands upon the benefits of digital imaging's Novel Enhanced Quantum Representation (NEQR). Our research and testing have demonstrated that our method is secure against a variety of attacks and provides defense against present and potential dangers while preserving the steganography characteristics of capacity and imperceptibility, making it one of the greatest choices for transmitting confidential data.

Despite promising prospects, quantum steganography faces challenges such as quantum state fragility and hardware constraints, requiring ongoing research to unlock its full potential in safeguarding sensitive information.
Abstract 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.
In response to rising cyber threats and the limitations of traditional security, this project proposes a hybrid framework combining quantum cryptography and text-based steganography for secure and concealed communication. Using the BB84 Quantum Key Distribution (QKD) protocol, a secure quantum key is established and extended with SHA-256 to encrypt a secret message via XOR operations. The encrypted data is embedded into a cover text using three steganographic techniques: case-based, zero-width, and color-based methods, the latter including double-color and double-color overlay variants. The techniques are evaluated on embedding efficiency, payload capacity, entropy, and deviation percentage. Among them, double-layer color-based steganography demonstrates superior performance, achieving up to 6 bits/symbol and 95% efficiency, with minimal error and high integrity. The system is implemented using Qiskit and HTML rendering, validating its practical feasibility. This dual-layer security model ensures confidentiality and invisibility, offering a robust, quantum-enhanced approach to secure communication in sensitive applications.
In the realm of cybersecurity, the demand for robust encryption and secure data hiding techniques has intensified with the proliferation of digital communication and sensitive information exchange. This paper explores integration of QC advancements for enhancing the security of two critical cryptographic applications: Advanced Encryption Standard (AES) encryption and Least Significant Bit (LSB) image steganography. Quantum computing introduces the concept of qubits, which harness quantum mechanical phenomena to perform computations that classical computers struggle to achieve efficiently. By leveraging qubits, AES encryption can potentially benefit from enhanced key generation and encryption processes, thereby strengthening data confidentiality against conventional and future quantum attacks. Additionally, this paper investigates the application of quantum-inspired techniques to optimize the LSB method in image steganography. LSB embedding involves hiding data within LSB of image pixels, technique vulnerable to statistical attacks. Quantum-inspired approaches aim to mitigate these vulnerabilities by improving embedding efficiency and robustness without compromising image quality. Through theoretical analysis and simulation studies, this research evaluates the feasibility and potential benefits of integrating quantum computing into AES encryption and LSB steganography. The findings underscore the promise of quantum-enhanced methods in fortifying data security across digital platforms, laying the groundwork for future advancements in quantum cryptography and information hiding techniques.
