Abstract: In an era dominated by digital communication, ensuring the security and confidentiality of transmitted data has become increasingly critical due to rising cyber threats and pervasive surveillance. Steganography—the art and science of hiding information within seemingly innocuous media—offers a covert layer of protection that complements traditional encryption methods. This paper presents a comprehensive exploration of steganography, covering its historical evolution, fundamental principles, classification, and various embedding techniques and applications. It also investigates steganalysis, the countermeasure used to detect and analyze hidden information. Furthermore, the study includes a comparative evaluation of steganography techniques . Real-world case studies are presented to illustrate both the practical applications and potential misuse of steganography. Through a comprehensive analysis, we highlight steganography's growing role in modern data security as a discreet and powerful method for protecting information in diverse digital environments.
