1. Secure Steganography App for Image and Audio Protection Hiding Secrets in Plain Sight Your Name / Team Name

2. Introduction Steganography: Art of hiding secret data inside ordinary files (images/audio). Why it matters: Protects sensitive information, more secure than encryption alone. Example: Sending a secret message inside a photo without suspicion.

3. Problem Statement Growing cyber threats & data leaks. Encryption alone is detectable. Need a method to hide + protect data invisibly.

4. Objectives Develop a secure app for hiding & retrieving data. Support images & audio as cover files. Provide encryption + steganography for double security. Easy-to-use interface for non-technical users.

5. Methodology Encryption Phase: Convert secret data into cipher text. Embedding Phase: Hide cipher text into image/audio (using LSB method). Decryption Phase: Extract & decrypt hidden data. Tools used: Python, Tkinter/Flask, AES encryption, PIL/NumPy.

6. Features of the App Dual Security (Encryption + Steganography). Image Steganography. Audio Steganography. Simple User Interface. Fast processing & preview option.

7. Implementation Programming Language: Python Libraries: PIL, NumPy, Tkinter, PyCryptodome Output: Encrypted Image/Audio files Demo screenshots of app (optional).

8. Results Successfully embedded messages in images/audio. Hidden data was undetectable to naked eye/ear. Decrypted data matched original. Example: before & after image comparison.

9. Benefits Secure data sharing without suspicion. Protects against cyberattacks & surveillance. Applications: Military communication, Medical records, Personal data protection.

10. Conclusion App provides a robust security layer. Combines encryption with steganography. Easy, reliable, and effective for real-world data protection. Future Scope: Cloud integration, Video steganography, AI-powered detection resistance.
