Steganography is an information security technique that enables the concealment of data within digital objects without being detected by other users. In the current digital era, this technique is highly valuable for ensuring data security and privacy in digital communication. This paper explores the uses and applications of steganography in the digital age by analyzing existing literature and global research findings. The literature review demonstrates the importance of steganography in data protection and information security, identifying various applications such as banking information security, email communication, and the protection of medical images. The research methodology employed a systematic review of scientific literature for data collection. The global findings indicate that steganography is a widely used technique across different domains, and its application helps maintain information privacy and security. However, its disadvantages include the potential malicious use of the technique for criminal activities. In the discussion section, the obtained results were evaluated, comparisons were made, and challenges associated with the use of steganography in the digital age were identified. In the conclusion section, the most relevant information was summarized, key findings were highlighted, and recommendations for future research were presented. In conclusion, steganography is a useful technique for protecting and ensuring information security in the digital age. Despite some disadvantages, its application can provide significant advantages in safeguarding data privacy and preventing potential cyberattacks.

After analysing the existing literature and conducting this research, it can be concluded that steganography has numerous applications in the digital age, both in civilian and military domains. It can be applied in various areas such as information security, privacy protection, and intellectual property protection, among others. Among the main advantages of steganography are its ability to transmit information secretly, the difficulty of detecting its use, and its flexibility to adapt to different types of files and information systems. However, some disadvantages have also been identified, such as the requirement for specialized technical knowledge and the possibility of misuse for illegal purposes. It is important to emphasize that steganography must be used responsibly and ethically, as its misuse can have serious consequences for individuals’ security and privacy. Additionally, further research and development of new techniques and tools are necessary to improve its effectiveness and reduce potential risks. In conclusion, steganography is a valuable tool in the digital age, offering a wide range of applications and possibilities. However, its use must be responsible and ethical, and further research is needed to fully understand its advantages and disadvantages. The study reveals that steganography plays a crucial role in various aspects of the digital age, ranging from information security to copyright protection and forensic investigations. Nevertheless, its use raises ethical and legal challenges that must be addressed to ensure an appropriate balance between privacy and security in the modern digital environment.
