In today’s digital world, protecting sensitive information is more important than ever. This project introduces a secure and user-friendly steganography system that hides secret messages inside RGB images using the Least Significant Bit (LSB) substitution method. To enhance security, the messages are first encrypted with the Fernet algorithm, ensuring that even if extracted, they remain unreadable without the correct key. The system allows users to easily encode and decode messages using custom encryption keys while maintaining the image’s original appearance. It also tests reliability by simulating real-world challenges like noise addition. Designed for personal, corporate, and military use, this approach provides a secure, efficient, and practical solution for confidential communication.
