Attendance Management System Using Indoor Localization Techniques

Recently, interesting in flexible working has been increased, and some central government and large companies are conducting flexible working. With the conducting of flexible working, workers are able to get a convenience but the cost of managing is increased. In this paper, we suggest a method of reducing the cost and managing efficiently. Our study determines the position of the workers using indoor localization techniques through the Wi-Fi fingerprint and smartphone, and records the office hours. The previous time and attendance systems have to install attendance recording device(e.g. Fingerprint Attendance System, RFID Card Attendance System) and are needed to manipulate manually. Our system doesn't need to install extra devices, and also doesn't need to manipulate manually. Our system automatically records the office hours. Also most of previous time and attendance systems have another weakness. They only record data when workers start and stop work. But our system exactly records office hours for each workplaces. In this paper, We introduce an effective time and attendance system in variety flexible working. Our experiments shows that our system workers’ detected office hours accurately. The accuracy of our time and attendance system was 98.7%. 논문 15-40-10-26 The Journal of Korean Institute of Communications and Information Sciences '15-10 Vol.40 No.10 http://dx.doi.org/10.7840/kics.2015.40.10.2068 2068 ※ This work was supported by the National Research Foundation of Korea grant funded by the Korean government, Ministry of Education, Science and Technology (NRF-2012R1A1A3006105). ° First and Corresponding Author : Hongik University, Dept. of Computer Engineering, Real-time System Lab., DI.Seo@mail.hongik.ac.kr, 학생회원 * Hongik University, Dept. of Computer Engineering, Real-time System Lab., {Daye.Ahn@mail.hongik.ac.kr, rhanha@hongik.ac.kr}, 학생회원 논문번호:KICS2015-04-129, Received April 17, 2015; Revised June 15, 2014; Accepted September 18, 2015 논문 / 실내 위치 추적 기법을 이용한 근태관리 시스템
