“…Hiding information in images through the RGB color layers has been used in several works related to steganography. Liu and Zhang [2], like Abbas et al [26] used this concept in their studies through the LSB method. The proposed algorithm uses the basis of this concept, differing in that it stores bytes directly for the RGB values of the created image(s).…”

This study aims to provide a solution for RSA over-encryption based on steganography variant to hide sensitive information that requires security. The current study describes a software program's implementation phases that allow technicians to re-encrypt a message, first encoded using RSA cryptosystems as an extra security layer. Subsequently, this text was converted into an array of bytes stored in Red, Green, and Blue (RGB) layers of one or more generated images, which will finally be sent to the receiver. The programming recursion technique was used to determine the number of images that need to be sent and the bytes corresponding to each of them. These images were created, reorganized, and encrypted according to pre-defined rules. The security of the proposed method relies heavily on the probability theory. Each of the possible patterns that can store data is equally likely to be chosen by an attacker. The program also uses as a conceptual base the Least Significant Bit Substitution (LSB) technique, with the difference that it directly stores bytes for the RGB values of the generated image(s). Our results indicate that the re-encryption is independent of a carrier image. The number of different ways to organize the pixels and the generated images suggests an acceptable security level. Moreover, it requires a not negligible computational power to decipher the pixels' original order and the channels containing relevant information.

“…While cryptography finds extensive usage in various everyday applications, both techniques have their respective domains of application and can potentially be combined for enhanced security measures. Steganography encompasses a wide range of techniques and can be applied in different forms, such as images, audio, video, and text, to many applications, for example, IoT communication [7,21,40], military [72], cloud storage [2,18,47,68], and more [28,31,32,38,90,95]. The growth of interest in steganography was sparked in two ways: the multimedia industry could greatly benefit from possible water-marking techniques, and restrictions on cryptographic schemes by governments triggered interest in alternative ways for communication to stay secretive [8].…”

In an interconnected world, ensuring the confidentiality and security of digital data has become increasingly vital. Cryptography and steganography serve as two primary approaches to information security. Cryptography shields the content of messages, while steganography conceals their existence. While these methods find applications in diverse fields, there is ongoing exploration regarding the potential benefits of combining them. However, the practicality of merging these techniques hinges upon various factors, including bandwidth limitations, latency constraints, and specific security requirements pertinent to a given scenario, such as electronic voting. This review focuses on journal articles and conference papers implementing the integration of steganography and cryptography in practical applications. Notably, the majority of research conducted so far has been limited to medical applications, whereas image steganography finds widespread use across diverse domains. In this novel research, we do the extensive review in the following ways: i) By gaining valuable insights into the real-world applications being explored in the existing literature., and ii) By categorizing these applications based on their domain of applications (e.g., Medical or Transportation) and technological domain (e.g., Cloud Computing or Internet of Things). Moreover, this review thoroughly analyses the advantages and limitations associated with these implementations and discusses them from three evaluation perspectives: security, performance, and user experience. The categorization of applications facilitates guidance for future research in unexplored areas, while the three evaluation perspectives provide crucial aspects to consider when analyzing or evaluating real-world implementations.

“…Meanwhile we would focus more about Arabic steganography techniques in addition to how we would improve the techniques so they would be unpredicted and would be more effective to be used in. Steganography is a way to provide a communication secretly between two persons by embedding data in a digital file that could be an image, video, audio, or text as cover using a key to produce a stego-file that will make it very difficult or nearly impossible for the person in the middle to detect the stego-file and only the sender and the http://journals.uob.edu.bh receiver are able to detect and understand the file [16]. Embedding the data to make a stego-file is not a simple task and there are things to consider like size of the cover which should not be increased as much, and there are multiple features that we should consider when applying stenographic procedures: Firstly, the embedding capacity, which is how much can we change and alter the size of embedded data without affecting or changing the original quality.…”

Steganography is a technique used for hiding secret information or data in a text, image, audio, or video to make it harder for the attackers to detect the hidden information. Many techniques were developed that target the English language but only few Arabic text steganography techniques exist. In this paper, we explore steganography and its types, presented multiple techniques for Arabic steganography, discuss advantages and disadvantages of each technique and described the main functions in our implemented code, after that, we evaluate each technique and suggested improvements that can benefit each technique to enhance their capacity and minimize any problems that can face them to reach our main goal, which is to improve this field to be able to implement its without worrying about any disadvantages that the techniques may have.
