#### **5.2 Companion Web/Mobile Portal**
- Hosted on a cloud service (AWS, Azure, or DigitalOcean).
- Secure API communication with the Raspberry Pi.

---

### **6. Security Requirements**

#### **6.1 Authentication**
- Enforce secure login protocols (OAuth2.0, JWT).
- Two-factor authentication for added security.

#### **6.2 Data Protection**
- Encryption of user data and API keys.
- GDPR compliance for user data privacy.

#### **6.3 Secure Payments**
- PCI DSS compliance for payment processing.

---

### **7. Performance Optimization**

#### **7.1 Optimized for Raspberry Pi**
- Utilize hardware-accelerated video decoding for the video avatar API rendering.
- Lightweight backend and frontend to reduce CPU/GPU load.

#### **7.2 Offline Mode**
- Cache the avatar’s response for limited offline usage (if the internet drops temporarily).

---

### **8. Maintenance and Scalability**

#### **8.1 Updates**
- OTA (Over-the-Air) updates for software.
- Push notifications for feature updates and maintenance schedules.

#### **8.2 Logs and Monitoring**
- Admin access to error logs and API health metrics.
- Auto-notifications for critical issues (e.g., API downtime).

#### **8.3 Future Scalability**
- Modular architecture for adding new features (e.g., advanced analytics).
- Scalability for handling thousands of users if the software is commercialized.
