  • Abstract:
  • This project provides a web-based application that uses steganography techniques to embed and extract messages from photographs utilizing Caesar cipher encryption and Quantum Key Distribution (QKD) for enhanced security. The program allows users to upload photos for message embedding or stego images for message extraction using Flask and OpenCV. By employing the Least Significant Bit (LSB) approach, the encrypted communications seamlessly merge with the image pixel data. Users can input their messages and a shift value for encryption, and the system offers robust error handling for file uploads and processing. By extracting and decrypting the encoded message from the steno picture, the extraction process provides an intuitive interface for encrypted communication. By using QKD, the application makes it easier to create and exchange cryptographic keys across quantum channels, hence lowering the risk of key interception. This project demonstrates the practical application of cryptography and steganographic techniques, highlighting the potential for secure data transit across a variety of domains.
