At the end of the lesson, you will understand steganography access methods, data handling techniques, and apply them to secure information.
What do you already know about steganography and its data handling techniques?
Module 1: Introduction to Steganography
Understand the basics of steganography, its history, and its importance in modern data security.
Unit 1.1: What is Steganography?
Steganography is the practice of concealing messages within other non-secret text or data.
Unit 1.2: Historical Background
Explore the evolution of steganography from ancient times to the digital age.
Unit 1.3: Importance in Modern Security
Steganography protects information by hiding it within ordinary files, enhancing security.
