Research on an Authentication Algorithm for an Electronic Attendance System in the Constructing of a Smart Campus

This paper presents a proposal for a large-scale lecture authentication algorithm for an electronic attendance system. The utilization rate for existing electronic attendance systems is low. Because it couldn't solve the problems that occur by special conditions of university such as vicarious attendance, bottlenecking during attendance check-in, and attendees departure at intermission. The most important things are not the authentication problems or errors on the technical issues. Instead, issues are related to attempts to check attendance simultaneously by a number of students, failure to prevent vicarious attendance, and the uncertainties of students remaining in the classroom following check-in. The authentication algorithm of the proposed system uses smartphone in attendance check. So it will save time and prevent bottlenecks as large numbers of students will not need to stand in line to check-in their attendance in the wall-mounted attendance device. And, it will minimize, if not eliminate, students who might leave at intermission. Because the instructor can verify attendance many times with the simplicity of the attendance check verification procedure and the short authentication time. Thus, the proposed algorithm will facilitate the implementation of a smart electronic attendance system in the construction of the smart campus.
