Who are you, really? Not your name. Not your age. Your behavior.
DBIP builds a dynamic digital identity for every user — not from boring surveys, but from how they actually behave. Every click, every preference, every micro-decision shapes who they are in the system. Companies can then use these identities to simulate real user responses before launching a product.
| Feature | Description |
|---|---|
| 🔐 Auth | Register & login with JWT-secured sessions |
| 🖱️ Interactions | Submit micro-interactions (category, price, brand, decision speed) |
| 🧬 Identity Engine | Rule-based engine computes your behavioral profile in real-time |
| 📊 Dashboard | Visualize your identity with radar charts and category bars |
| 🏢 Simulation | Companies input a product and see predicted Like / Neutral / Dislike across all users |
No ML. No black box. Pure logic — transparent and explainable.
Price Sensitivity → majority of price range choices (low = high sensitivity)
Brand Preference → majority of branded vs generic choices
Decision Style → avg decision time < 10s = Fast, > 20s = Slow
Category Interests → top 3 most interacted categories
Every new interaction instantly updates the profile. Watch your identity evolve in real-time.

- Storage — In-memory (prototype) — no database required
Final year project demonstrating the concept of behavioral identity profiling — a privacy-conscious alternative to traditional user surveys, where identity emerges naturally from interaction patterns.
