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.
