This project explores a novel approach to data security by combining DNA codon encryption with image steganography. Inspired by the way genetic information is stored and transmitted in biological systems, this method maps plaintext into codon sequences (triplets of nucleotides) and embeds them within digital images for secure transmission.
🔑 Key Features
DNA Codon Encryption: Text is converted into codon sequences (A, T, C, G) for biologically inspired encryption.
Image Steganography: Encoded DNA codons are embedded inside images without noticeable visual distortion.
Dual-Layer Security: Even if the image is intercepted, the hidden codon sequences require decryption.
Encode & Decode Modules: Scripts to encode plaintext → codons → stego-image and decode stego-image → codons → plaintext.
Upgradeable Design: Can be extended with quantum key distribution (QKD) or IoT hardware interfaces (ESP32 + OLED) in future versions.
🛠️ Tech Stack
Languages: Python (for core encryption + steganography)
Libraries: NumPy, OpenCV/PIL, etc.
Future Hardware: ESP32 + SSD1306 OLED for key generation/display
🚀 How It Works
Input Text → converted into DNA codon sequence.
Codon sequence is embedded inside an image file (PNG/JPEG).
Decoder extracts codons and translates back to original text.
🎯 Applications
