+# NetraID - Production-Grade AI Face Authentication Attendance System
+
+NetraID is an enterprise-grade, 100% free, and self-hosted face-authentication attendance platform. Using advanced facial biometrics, liveness classifiers, and high-performance vector indexes, it provides an offline, secure, and production-ready system suitable for digital kiosks, schools, colleges, and startups.
+
+---
+
+## Technical Stack & Architecture
+
+NetraID uses clean-architecture layers (Repository and Service layers) to structure code modularly.
+
+- **AI & Computer Vision**: SCRFD (Face Detection), ArcFace (Face Recognition), MiniFASNet (Silent Face Anti-Spoofing) running on pure ONNX Runtime.
+- **Backend API**: Python 3.12, FastAPI, SQLAlchemy 2.0, Alembic, Pydantic V2, JWT RBAC, and Audit Logging.
+- **Voice synthesis**: Offline `pyttsx3` text-to-speech engine.
+- **Vector Database**: PostgreSQL 16 with the native `pgvector` extension.
+- **Frontend Kiosk & Dashboard**: Next.js 15, TypeScript, Tailwind CSS, Framer Motion, and Apache ECharts.
+- **Deployment**: Docker, Docker Compose, and Nginx.

+
+---
+
+## Setup Instructions
+
+NetraID runs natively on both **Windows** and **Linux**.
+
+### Option A: Quick Launch via Docker Compose (Recommended)
+
+1. **Clone & Navigate**:
+   ```bash
+   cd NetraID
+   ```
+
+2. **Download AI Model Weights**:
+   Run the model downloader script locally to pull the ONNX models to the `./models` folder, or let the backend do it on boot. To run it manually:
+   ```bash
+   cd backend
+   python -m pip install -r requirements.txt
+   python app/core/download_models.py
+   cd ..
+   ```
+
+3. **Start Stack**:
+   ```bash
+   docker compose up --build
+   ```
+
+4. **Access Applications**:
+   - **Dashboard & Kiosk**: [http://localhost](http://localhost) (Nginx proxy)
+   - **FastAPI API Swagger Docs**: [http://localhost/docs](http://localhost/docs)
+   - **PostgreSQL Database**: Port `5432`
+
+---
+
+### Option B: Local Development Setup (Windows & Linux)
+
+#### 1. Setup PostgreSQL + pgvector
+Make sure you have a running PostgreSQL instance and install the `pgvector` extension:
+```sql
+CREATE EXTENSION IF NOT EXISTS vector;
+```
+
+#### 2. Run Backend
+1. **Initialize Virtual Env**:
+   ```bash
+   cd backend
+   python -m venv venv
+   # On Windows:
+   venv\Scripts\activate
+   # On Linux:
+   source venv/bin/activate
+   ```
+2. **Install Packages**:
+   - *On Linux*: Install `espeak` for pyttsx3 and Mesa GL for OpenCV:
+     ```bash
+     sudo apt-get install -y libgl1-mesa-glx libglib2.0-0 espeak
+     ```
+   - *On Windows*: Python packages will install SAPI5 dependencies automatically.
+   ```bash
+   pip install -r requirements.txt
+   ```
+3. **Download ONNX Models**:
+   ```bash
+   python app/core/download_models.py
+   ```
+4. **Boot Server**:
+   ```bash
+   uvicorn app.main:app --reload --port 8000
+   ```
+
+#### 3. Run Frontend
+1. **Navigate & Install**:
+   ```bash
+   cd ../frontend
+   npm install
+   ```
+2. **Boot Dev Server**:
+   ```bash
+   npm run dev
+   ```
+   Open [http://localhost:3000](http://localhost:3000) in your browser.
+
+---
+
+## System Workflows
+
+### 1. Seeding & Credentials
+On startup, the system seeds default values.
+- **Initial Super Admin**: `admin@netraid.ai` / `Admin@NetraID2026`
+- **Default Shift Timing**: Start: `09:00`, End: `17:00`
+- **Grace Period**: 15 minutes.
+- **Similarity Thresholds**: Face Cosine distance: `0.60`, Liveness threshold: `0.75`
+
+### 2. Biometric Face Enrollment (10 Poses)
+To complete a registration, navigate to the **Employees** page, select a user, and click **Camera**. The admin must capture/upload 10 distinct poses to achieve high-accuracy matches:
+- *Poses*: Front, Left, Right, Looking Up, Looking Down, Smiling, Neutral, Indoor Light, Outdoor Light, Glasses (Optional).
+- Reference embeddings are saved as L2-normalized 512-D float vectors inside PostgreSQL.
+
+### 3. Kiosk Scanning & Liveness
+When an employee stands in front of the kiosk webcam:
+1. The system captures frames and scans for exactly one face (SCRFD).
+2. Runs **Silent-Face-Anti-Spoofing** (MiniFASNet). If the liveness score is below `0.75`, the scan is rejected as a spoof (e.g. photos, phone screen).
+3. Extracts the 512-D face embedding (ArcFace) and runs a **pgvector cosine distance** query:
+   ```sql
+   SELECT * FROM face_embeddings 
+   ORDER BY embedding <=> :search_vector LIMIT 1;
+   ```
+4. Calculates similarity `1.0 - distance`. If similarity is $\ge 0.60$, the employee is identified.
+5. Marks Check-In (first swipe) or Check-Out (subsequent swipes) and logs the entry.
+6. Synthesizes a greeting offline using `pyttsx3` (Windows SAPI5 / Linux espeak) based on time-of-day:
+   - `05:00 - 11:59`: "Good Morning"
+   - `12:00 - 16:59`: "Good Afternoon"
+   - `17:00 - 23:59`: "Good Evening"
