Cryptography-Based Steganography System for Secure and Hidden Data Transmission

The objective of this project is to design a cryptography-based steganography system that securely hides encrypted information inside digital media files for covert communication.

Study steganography and encryption integration techniques.

Encrypt sensitive data using AES.

Embed encrypted data into image or audio files.

Implement extraction and decryption module.

Test robustness against steganalysis attacks.

Measure embedding capacity and distortion metrics.

Evaluate performance and secrecy level.

Document experimental results and security evaluation.
