ClassConnect

ClassConnect is an application designed to help teachers take attendance efficiently with just a click on their mobile devices. This system integrates biometric authentication and geolocation verification to ensure accurate attendance tracking.

Workflow

1. Login and Channel Creation:

   • Teachers and students open their respective interfaces of the application.
   • Upon login, a dedicated channel is created for each teacher on the WebSocket server.

2. Student Connection:

   • Students can join their respective teacher's channel by logging in.

3. Starting Attendance:

   • When a teacher clicks on the "Start" button, all connected students on that channel will receive a signal indicating the start of the attendance session.

4. Biometric Authentication:

   • An interface will open on the students' devices, prompting them to authenticate themselves using their biometric data (e.g., fingerprint).

5. Geolocation Check:

   • The student's geolocation is captured to ensure they are within a specified radius of the teacher.

6. Attendance Marking:

   • If a student successfully authenticates their biometrics and is within the defined radius, their data is stored in the session database, and they are marked as present.

7. End of Session Report:

   • When the teacher clicks the "Stop" button, a report of all students marked present during the session is generated from database and provided to the teacher.

System Architecture

The system architecture is divided into three major phases:

1. Client Connection and Session Initialization:
2. Attendance Verification and Marking:
3. Session Closure and Report Generation:

Deployment

The project is deployed on Azure under the resource group ClassConnect. The following are the key components of the architecture:

1. WebSocket Server: Handles communication between teachers and students (named as student on Azure) .
2. Flask Servers: Hosts the Flask applications (named as flask-servers on Azure).
3. MySQL Database Server: Manages session data and stores attendance records (named as classconnect-database on Azure).
