Smart Attendance Management System Using Encrypted QR Codes and Load Balancing

Over the recent years, lots of efforts have been undertaken to improve the existing monotonous and time consuming task of recording attendance in a classroom which includes systems such as biometric scanners and RFID devices. Taking into account various factors such as cost, ease of use and scalability, an encrypted QR code based attendance system has been proposed in this paper based on the students location to prevent proxy. The system will send every student within the boundaries of the classroom a unique QR Code in order to mark their attendance. Digital attendance reports and regular data backups help in enhancing the efficiency and reliability of the system. Considering the large number of requests coming through in an educational institution, a multi-server architecture with load balancing to distribute the heavy traffic has been proposed. A comparative study of four load balancing algorithms like round robin, ip hash, least connection and weighted round robin was analysed based on their performance on the system.
