Attendance systems are fundamental in educational institutions,
workplaces, and various organizations. Traditional attendance management approaches
suffer from vulnerabilities such as fraud, data tampering, and lack of legal accountability.
This paper proposes a novel framework that integrates blockchain technology—
specifically smart contracts—with IoT-based attendance data collection to enhance trust,
immutability, and legal enforceability. By leveraging the TrustContract platform by
TrustMe.uz, the system ensures tamper-proof, timestamped attendance records with legal
validation. The proposed solution’s architecture, smart contract design, IoT integration,
and performance evaluation are presented. Comparative analysis with manual and IoT
only systems highlights significant improvements in security, privacy, and scalability.
Challenges and future research directions related to privacy preservation and widespread
adoption are also discussed.
