+# Sentinel Telemetry Dashboard - Implementation Summary
+
+## 🏗️ What Was Built
+
+I've created a comprehensive **advanced MVP** telemetry collection server and security dashboard for the Sentinel privacy protection system. Here's what was implemented:
+
+### 🔧 Core Components
+
+1. **Telemetry Collection Server** (`telemetry-server/main.py`)
+   - FastAPI-based REST API server
+   - SQLite database for storing telemetry events
+   - Real-time data collection from Sentinel instances
+   - Risk assessment and categorization
+
+2. **Security Dashboard** (HTML Templates)
+   - Professional web interface for security officers
+   - Real-time privacy monitoring
+   - Interactive charts and visualizations
+   - Event filtering and detailed analysis
+
+3. **Authentication System**
+   - Fake login system for demo purposes
+   - Session management with cookies
+   - Role-based access control ready
+
+4. **Enhanced Sentinel Integration**
+   - Improved telemetry reporting in original Sentinel code
+   - Better error handling and logging
+   - User and session tracking capabilities
+
+## 📊 Dashboard Features
+
+### Main Dashboard
+- **Live Statistics**: Total events, secrets detected, unique users, active sessions
+- **Timeline Visualization**: Privacy events over time using Plotly
+- **Risk Distribution**: Pie chart showing HIGH/MEDIUM/LOW risk events
+- **Top Applications**: Bar chart of apps with most privacy violations
+- **Recent Events**: Latest privacy events with quick preview
+- **Auto-refresh**: Dashboard updates every 30 seconds
+
+### Events Page
+- **Detailed Event Table**: Complete listing of all privacy events
+- **Event Details Modal**: Click to view full event information including:
+  - Original prompt with sensitive data
+  - Sanitized output with masked tokens
+  - List of detected secrets
+  - Risk assessment and metadata
+- **Filtering Capabilities**: Filter by risk level, user ID, date range
+- **Export Ready**: Structure ready for data export features
+
+### Security Features
+- **Risk Assessment**: Automatic calculation based on number of secrets:
+  - HIGH: 5+ secrets detected
+  - MEDIUM: 2-4 secrets detected  
+  - LOW: 1 secret detected
+- **User Tracking**: Each user has an `app_id` to identify them
+- **Session Tracking**: Each session gets a unique `session_id`
+- **Data Classification**: Clear visualization of what private data is being sent
+
+## 🔌 API Integration
+
+### Telemetry Collection Endpoint
+```
+POST /api/report
+```
+Receives telemetry data from Sentinel instances with:
+- `app_id`: User identifier
+- `session_id`: Session identifier
+- `prompt`: Original prompt with sensitive data
+- `secrets`: Array of detected secrets
+- `sanitized_output`: Sanitized prompt with masked tokens
+- `timestamp`: When the event occurred
+
+### Data Retrieval Endpoint
+```
+GET /api/events
+```
+Provides privacy events data for the dashboard (authenticated).
+
+## 🛡️ Enhanced Sentinel Integration
+
+### Improved Reporting
+- Fixed bug in original Sentinel code (print statement error)
+- Enhanced logging with user ID, session ID, and secret details
+- Better error handling and telemetry transmission
+
+### Environment Configuration
+```python
+# Configure Sentinel to use telemetry server
+os.environ["PS_SERVER_URL"] = "http://localhost:8000"
+os.environ["PS_APP_ID"] = "your-app-identifier"
+```
+
+## 🎯 Usage Scenarios
+
+### For Security Officers
+1. **Login** to dashboard with demo credentials
+2. **Monitor** real-time privacy events
+3. **Analyze** which users are sending sensitive data
+4. **Investigate** specific privacy violations
+5. **Assess** risk levels across applications
+6. **Track** privacy compliance over time
+
+### For Developers
+1. **Integrate** Sentinel with existing applications
+2. **Configure** telemetry reporting
+3. **Monitor** privacy protection effectiveness
+4. **Debug** false positives or missed detections
+
+## 🚀 Getting Started
+
+### 1. Start the Telemetry Server
+```bash
+cd telemetry-server
+pip install -r requirements.txt
+python main.py
+```
+
+### 2. Generate Demo Data
+```bash
+python demo_data.py
+```
+
+### 3. Access Dashboard
+- URL: http://localhost:8000
+- Login: admin / admin123
+
+### 4. Use with Sentinel
+```python
+from sentinel.prompt_sentinel import sentinel
+from sentinel.sentinel_detectors import RegexSecretDetector
+
+# Configure telemetry
+os.environ["PS_SERVER_URL"] = "http://localhost:8000"
+os.environ["PS_APP_ID"] = "my-app"
+
+# Use Sentinel with telemetry
+@sentinel(detector=RegexSecretDetector())
+def call_llm(prompt):
+    return llm_api(prompt)
+```
