Attendance as a Service: A multi-layered system design in attendance applications for Covid-19

Abstract

During Covid-19, there has been a requirement of a distributed architecture for contact-less and available smart application which deploys in personal mobile devices. However; the single-layer architecture of the other similar applications in the literature, has not been met the user requirements according to the preliminary tests. Moreover, the conventional ones offer a high-cost architecture. To overcome these challenges; Software as a service (SaaS) has been more preferred for the integration of distributed applications in the cloud market in a cost-efficient way. Therefore; we propose an Attendance as a Service; i.e. new multi-layered system which includes such technologies as QR code, face recognition and fingerprint to meet the reliability and contact-less performing. In the performance evaluation, the proposed system serves with lower delay and higher scalability when compared to conventional ones. It has been observed that the multi-layered structure provides 8 milliseconds of gain in delay compared to the traditional one and overcomes the students' inability to attendance due to server density.
