Several approaches and techniques exist to make communication via the internet secure, one of these approaches is steganography. Computer steganography can be defined as a method of hiding data in cover media so that others are not aware of its existence. Quantum computers, built on the principles of quantum physics, have introduced new possibilities for researchers in security and computer science. This paper explores the fundamentals of quantum computing, its achievements, and the challenges and future prospects it presents in the field of cryptography and steganography. Quantum computers give us a new approach to different kinds of complicated problems in security fields by creating multi-state computing spaces.

Quantum key distribution (QKD) is a secure communication method that implements a cryptographic protocol involving components of quantum mechanics.
The concept of Cryptography and Steganography is not a new technique, even though it is ancient but not static. In Cryptography and Steganography the new emerging techniques are done using Quantum Mechanics and Quantum Physics. In this paper, mainly works on how to use Quantum Technique in cryptography system and in field of steganography. Steganography is a process of hiding information of the different types of media files (audio, text, image and video) in another media files. In this paper, mainly the quantum steganography works for two imagery files. The quantum secret image will be hiding in the Quantum Cover image. In this process of hiding of information or image, need to select the pixels. The Qbits used to store the secret image are two most and least significant Qbits. The secret image will be scrambled first, using Arnold’s cat map technique, and then will be embedded into Quantum Cover picture. The Stegno Image is sufficient to extract the secret information. The NEQR quantum representation model is used for converting image into quantum states. The simulation result and analysis demonstrates that the proposed scheme has good visibility and high embedding capacity.
Many people use the internet for communication, but there is a problem with protecting their information. To ward off the attackers, they need secure communication such as cryptography and steganography techniques. To maintain the security of information, improving the technology of steganography is necessary. In this paper, we propose a novel method to create the secret quantum text steganography more difficult for attackers to intercept. Firstly, the proposed method generates a secret message as a binary string by combining the secret key of the BB84 protocol and message. Then, the secret message is embedded in the first character of each line in the cover text. In the cover text, the first character of each line is changed to the case of the specific character, such as uppercase or lowercase, according to the secret message to be hidden. The cover text uses the English language. Experimental results describe the effectiveness of the proposed method for hiding data within the cover text while maintaining a high level of security. The proposed model is able to secure data transmission because it was difficult for the attacker to reveal or intercept data.
This paper describes a novel steganography algorithm that combines quantum computing with the least significant bit technique (LSB). Using the quantum properties, along with the Python programming language and the Qiskit framework for the circuit simulation, a sub-image can be hidden inside a usual image. For a gray image, this article presents how the LSB of each of the first 16 pixels on the edges can be used to hide two threshold values, that are then used to filter out the image and reveal the secret message. The speedup, compared to the classical version, is possible due to the quantum representation of an image (NEQR is used in this paper) and the efficiency of the novel multi-bit quantum comparators.
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.
Steganography is the art and science of hiding the fact that communication is taking place. Steganographic systems can hide messages inside of images or other digital objects. To a casual observer inspecting these images, the messages are invisible. The security of a classical steganographic system relies on the secrecy of the encoding system. Once the encoding system is known, the steganographic system is defeated. However, modern steganography should be detectable only if secret information is known, namely, asecret key. Because of their invasive nature, steganographic systems leave detectable traces within a medium's characteristics. This allows an eavesdropper to detect modified media, revealing that secret communication is taking place. Although the secret content is not exposed, its existence is revealed, which defeats the mainpurpose of steganography. This work has as purpose to expand the field of applicability of the steganography from the classical informatics to the quantum one.
