## **Introduction**
Steganography is the practice of concealing messages or data within other non-secret files, such as images, audio, videos, or even text. Unlike cryptography, which focuses on making data unreadable, steganography aims to hide the very existence of the communication.
## **How Does Steganography Work?**
Steganography techniques vary depending on the medium used:
1. **Image Steganography** – Hiding data within the pixels of an image (e.g., LSB substitution).
2. **Audio Steganography** – Embedding information in sound files (e.g., echo hiding, phase coding).
3. **Video Steganography** – Concealing data in video frames or metadata.
4. **Text Steganography** – Using whitespace, font changes, or invisible characters to hide messages.
## **Applications of Steganography**
- **Digital Watermarking** – Protecting copyrights by embedding hidden identifiers.
- **Covert Communication** – Secure data transmission without raising suspicion.
- **Cybersecurity** – Detecting and preventing hidden malware or exfiltration attempts.
## **Challenges & Detection**
While steganography is powerful, forensic tools can detect anomalies in files (e.g., statistical analysis, machine learning).
## **Conclusion**
Steganography remains a fascinating blend of art and science, playing a crucial role in privacy, security, and digital forensics.
