Development of a Biometric Toilet Monitoring System for Final Examinations: A Socio Technical Perspective

Abstract

Examinations are high stakes environments in which fairness and trust are paramount. Traditional manual approaches to controlling access to restroom facilities during examinations often require invigilators to record the names and entry times of candidates on paper. Such manual logging leaves opportunities for bias, error or impersonation. A biometric toilet monitoring system was designed to address these vulnerabilities by coupling fingerprint authentication with real time data synchronization to a web server. This paper revisits that engineering project through a socio technical perspective. It traces the motivations for automating restroom access, details the hardware and software architecture, reproduces key figures and tables, reports empirical performance findings and situates the system within broader debates about surveillance, consent, privacy and digital inclusion. Ultimately the work demonstrates that a thoughtfully implemented biometric access system can enhance exam integrity while raising questions about equity, autonomy and trust.
