Development of QR Code-Based Authentication System for Admitting Students into Examination Hall for Polytechnics in Nigeria

This study implements a QR code-based authentication system at Federal Polytechnic Ukana, Nigeria, as a technological solution to the challenges of traditional manual verification methods in examination management. The system architecture includes a database management module (MySQL), a QR code generation module (Python QR Code library), and an authentication module (Android mobile application). The system integrates web-based and mobile platforms, enhancing accessibility and usability. Advanced Encryption Standard (AES) is used to secure QR code data. The system undergoes rigorous testing to validate its functionality, accuracy, and security. A pilot deployment in two departments over a two-week examination period showed improved efficiency, reduced impersonation cases, and enhanced overall examination integrity. Performance metrics showed reduced verification time, increased accuracy, and system reliability under varying conditions. The findings confirm that QR code technology significantly enhances examination security and operational efficiency. However, challenges such as internet connectivity dependency and potential QR code tampering are acknowledged. Future research may explore the integration of biometric authentication and blockchain technology to strengthen security measures. The successful implementation at Federal Polytechnic Ukana provides a model for broader adoption, offering a scalable and cost-effective solution to modernize examination management across Nigerian polytechnics and beyond.
