Randomized QR-code scanning for a low-cost secured attendance system

Abstract

<span>Human resource management requires good documentation and good data processing. In workspaces such as offices and factories, employee salaries are determined by calculating attendance at each hour of work. Tracking and collecting attendance data for a large number of employees is a difficult thing to do. We need a secure system to facilitate the process of collecting and tracking presence data. We propose an attendance system that uses random quick response code (QR-codes) as one time password (OTP) to improve security. Employees are required to scan the QR-code within ten seconds before it is changed and randomized each time. The proposed attendance system facilitates data collection using employees’ smartphones and Mac-Address as unique identification numbers. The system is able to track employees’ arrival and departure times. We have implemented the system at the local university to collect lecturer attendance data then analyze its security and statistic in all scanning activities. The average time needed by a user to authenticate their presence in the system is 25.8877 seconds. The steps needed to sign in and out from the system are fewer than other previous researches. Those findings tell us that the approach is straightforward and more uncomplicated than other proposed methods. We conclude that randomized QR-code scanning is a relevant scheme to be applied in a secure attendance system.</span>

Enhancing attendance tracking using animated QR codes: a case study

“…To track attendance, the system utilizes employees' smartphones and Mac-Address as unique identification numbers. The authors conclude that the randomized QR-code scanning approach is effective and relevant for implementing a secure attendance system in workplaces such as offices and factories [17]. In summary, the use of QR codes for student attendance tracking has been shown to provide a reliable and efficient way to track attendance, while also enhancing student engagement and promoting a more collaborative learning environment.…”

“…Imanullah and Reswan [17] in the paper "Randomized QR-code scanning for a low-cost secured attendance system" in 2022 propose an attendance system that uses random QR-codes as one-time passwords (OTPs) to ensure security. The system requires employees to scan the QR-code within ten seconds before it is changed and randomized each time.…”
