Building on Series 2's Exploration of Steganography Applications emphasizes advancing from foundational uses of hidden communication toward deeper, more sophisticated practices. While earlier discussions highlighted basic applications such as covert messaging, watermarking, and digital rights management, this stage focuses on integrating steganography into broader cybersecurity frameworks, enhancing resilience against detection, and exploring its role in modern data protection. Methods evolve from simple least significant bit techniques to advanced transform domain approaches, which embed hidden data within compressed or frequency-based structures, making discovery far more difficult. By building on prior exploration, this phase underscores how steganography is not just a tool for secrecy but a dynamic discipline that adapts to emerging digital threats, ensuring secure and covert communication in increasingly complex technological landscapes.
This lecture is part of CYB 402 STEGANOGRAPHY: ACCESS METHODS AND DATA HIDING in the Cyber Security department. The course has 30 recorded lectures across 10 series, all free to watch. Read or download the CYB 402 lecture note to study alongside the video.
