Technology & Architecture

Core Technology Stack

  • Backend: Spring Boot (Java)
  • Frontend: Flutter
  • Database: MariaDB
  • Hardware Scripting: Python
  • Communication: REST APIs & WebSockets

Testing & Security

Rigorous Testing Approach

To ensure reliability, we employed a multi-faceted testing strategy:

  • Unit & Integrated Testing: Performed on all major components.
  • API Testing: Used Postman for backend endpoint validation.
  • Hardware Testing: On-site testing for the people counter and authentication modules.
  • Real-time System Testing: Utilized Mosquitto for MQTT architecture testing.

Robust Security Measures

  • JWT Token Usage for secure, stateless authentication.
  • Spring Security for authentication and access-control.
  • Hashed Passwords for secure user credential storage.
  • Role-Based Access Control (RBAC) to restrict system access.
