Designed a system that avoids traditional messaging channels by leveraging WebRTC encoded insertable streams to hide packetized payloads inside outbound video frames and reconstruct them on the receiving end. Key contributions and features: Built secure room-based peer-to-peer communication using WebRTC Implemented a WebSocket signaling server for SDP, ICE, and key exchange Designed covert data transfer by embedding encrypted payloads within encoded video frames Implemented end-to-end encryption using ECDH key exchange and AES-GCM Developed real-time packetization, embedding, extraction, and reconstruction pipelines Added live call metrics including FPS, latency, and payload overhead Architected a modular system with React (Vite) frontend and Node.js backend, integrating cryptographic workflows with real-time media pipelines. This project explores the intersection of real-time communication, cryptography, and steganography, demonstrating how media streams can be repurposed for secure and hidden data transmission.
