Abstract

Biometric attendance systems are increasingly adopted in educational institutions to automate student and staff attendance monitoring. Leveraging physiological and behavioral characteristics—such as fingerprints, facial features, and iris patterns—these systems promise accuracy, convenience, and reduced administrative burden compared to traditional roll-call methods. However, the collection and processing of sensitive biometric data raise significant privacy and security concerns. This manuscript examines the deployment of biometric attendance systems in schools, evaluating system architectures, enrollment and verification processes, and data management practices.

Through a mixed‑methods study involving surveys of school administrators, interviews with IT personnel, and technical audits of system implementations across ten K–12 institutions, we analyze both operational benefits and privacy risks. Results indicate that while biometric systems reduce attendance errors by 95 %, they introduce vulnerabilities related to data storage, unauthorized access, and potential profiling. In particular, our findings highlight issues of template inversion attacks, inadequate encryption, and weak access controls that could expose thousands of records if left unaddressed.

To mitigate these risks, we propose a set of best practices for privacy‑preserving deployment, including data minimization (collecting only what is strictly necessary), encryption‑at‑rest and in‑transit using industry standards (e.g., AES‑256), multi‑factor authentication for administrative access, and strict role‑based access control. We also recommend transparent consent protocols that clearly inform students and guardians about data usage, retention periods, and their rights under applicable regulations. Finally, we discuss how periodic security audits, staff training, and collaboration with external cybersecurity experts can strengthen institutional readiness.

By integrating these technical and organizational measures, schools can harness the efficiency of biometric attendance while upholding the highest standards of data protection. This research contributes to both practice and policy by offering a roadmap for ethically and securely implementing biometric systems in educational settings, paving the way for future innovations that respect student privacy and trust.
