About this episode

This episode covers the concept of steganography, its differences from encryption, and practical applications using the OpenStego tool.

In this lesson, you’ll learn about: steganography and how hidden data is embedded inside digital files without raising suspicion1. What Is Steganography?Steganography is the practice of hiding information inside other non-suspicious data such as images, audio, or video files.🔹 Key Idea Unlike encryption, which hides the content of a message, steganography hides the existence of the message itself.2. Steganography vs Encryption🔹 Encryption Scrambles data into unreadable form Clearly shows that secret communication exists 🔹 Steganography Hides data inside another file Makes the communication look completely normal 👉 Key Insight Steganography is about stealth, not just security.3. How Digital Steganography WorksHidden data is embedded inside a cover file, such as: Images (PNG, JPG) Audio files Video files 🔹 Common technique Modifying least significant bits (LSB) of pixels Using unused or redundant data space 👉 Key Insight Small changes are visually or audibly unnoticeable but can store hidden data.4. Types of Steganography Uses🔹 Legitimate uses: Digital watermarking (copyright protection) Metadata tagging Secure communication channels 🔹 Malicious uses: Hiding malware…
