BehaveGuard - Smart Authentication System

Passwords get stolen. MFA gets bypassed. But the way you type, move, and scroll? That's nearly impossible to fake. BehaveGuard is a continuous behavioral authentication engine that replaces static session trust with a living, real-time security score — built on your unique interaction patterns. No pop-ups. No friction. Just silent, persistent protection running in the background. In this video, I walk through the full system: live anomaly detection, the global security gate, and the admin SOC dashboard — all wired together end to end. ────────────────────────────── 🔍 What BehaveGuard does ────────────────────────────── → Continuous ML scoring — An Isolation Forest model (served via FastAPI) re-evaluates session trust every 2 seconds based on live behavioral signals. → Behavioral telemetry — Custom React hooks capture keystroke dynamics (CPS, flight latency), mouse velocity entropy, and scroll depth at high frequency. → Persistent security gate — A global HOC in Next.js enforces server-side strike counts from MongoDB, making the security layer impossible to bypass with a page refresh. → Dynamic escalation — When behavior drifts from baseline, the system automatically triggers a PIN challenge, downgrades access, or locks the session entirely. → SOC dashboard — A dedicated admin hub for real-time session monitoring, trust score visualization, and manual access restoration. ────────────────────────────── 🛠️ Tech stack ────────────────────────────── Frontend: Next.js 14 (App Router), Tailwind CSS, Framer Motion, Lucide ML engine: Python 3.10, FastAPI, Scikit-Learn, Pandas Backend: Node.js, Express.js, Mongoose (JWT Auth) Database: MongoDB Atlas ────────────────────────────── If you're working on security, ML, or full-stack systems — I'd love to hear your thoughts.
