Foundations of Secret Writing and Steganography refers to the study and practice of concealing information so that only intended recipients can understand or even detect its existence. Secret writing, often associated with cryptography, focuses on transforming messages into coded forms that require a key to decipher, ensuring confidentiality even if intercepted. Steganography, on the other hand, hides the very presence of communication by embedding messages within seemingly ordinary mediums such as images, audio files, or text, making detection difficult. Together, these disciplines form the backbone of secure communication, blending mathematical principles, linguistic techniques, and digital methods to protect sensitive information from unauthorized access while enabling covert exchange in both historical and modern contexts.
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.
