Architecture and security

The application is structured into backend and frontend components, with performance-critical tasks handled in Rust and C++ for speed and safety, and high-level logic in Python and TypeScript for flexibility.

Backend

• Python: Orchestrates application logic, Matrix protocol integration, and AI model execution (e.g., Whisper for translation). Uses pyo3 and ctypes for Rust and C++ bindings.

• Rust: Handles encryption (Signal Protocol, CRYSTALS-Kyber, AES-256-GCM), WebRTC peer connections, and session management with Tor for anonymous sessions.

• C++: Implements low-level audio processing (noise reduction, echo suppression, voice correction) and deepfake detection using RNNoise and OpenCV.

• Components:

  • Core: Manages sessions, WebRTC, and configuration.

  • Encryption: Implements hybrid encryption and watermarking.

  • AI: Processes audio and video with on-device AI models.

  • Security: Handles biometric authentication and SOS broadcasts.

Frontend

• TypeScript/React: Provides a responsive UI with components for calls, chats, settings, and SOS features.

• WebRTC Hooks: Manage low-latency audio/video streams.

• Tailwind CSS: Ensures a modern, consistent design.

Security Measures

Selenium AI Call prioritizes security through the following mechanisms:

• Local Rendering: All AI processing (audio, translation, deepfake detection) occurs on-device, minimizing data exposure to servers.

• Anonymous Sessions (Ghost Mode): Uses one-time identifiers and Tor-based routing to prevent tracking.

• Hybrid Encryption:

  • Signal Protocol for E2E encryption with Perfect Forward Secrecy.

  • CRYSTALS-Kyber for post-quantum security.

  • ZRTP for dynamic key sharing during calls.

• Attachment Encryption: Automatically encrypts photos and documents using AES-256-GCM.

• Self-Destructing Messages: Messages are deleted if a screenshot is attempted, protecting sensitive content.

• Biometric Authentication: Voice and facial analysis verify user identity at login.

• Digital Watermarks: Ensure audio/video authenticity, preventing tampering.

Scalability and Reliability

• WebRTC Modifications: Achieve <100ms latency for real-time communication.

• Matrix Protocol: Enables interoperability with other messengers (e.g., Signal, Telegram).

• Modular Design: Facilitates updates and community contributions.
