Abstract
본 논문에서는 RFID를 이용한 위치 추적 시스템을 제안하고자 한다. 수동형 RFID 태그를 사용자의 신분증에 삽입하여 위치추적 및 출입인증에 사용한다. 리더는 주기적으로 신호를 브로드캐스팅 하며, 리더는 태그의 응답 신호를 받아 사용자의 위치를 파악할 수 있다. 위치추적 방법으로는 신호의 세기에 따라 이동 경로를 파악할 수 있으며, 오래 머문 곳에 대한 위치를 이용하여 관심 분야 파악이 가능하다. 또한 백앤드 서버에 저장된 태그 ID값을 이용하여 보안구역 내 출입인증 시스템으로 활용이 가능하다. This paper suggests that location tracking system by RFID. It uses the location tracking and the authentication to entrance after inserts passive RFID tag into user Identification card. The readers periodically broadcast their signal, and then the readers understand where users are by analyzing them. In one of tracking systems, it is possible to detect the area where user had stayed for the longest time during moving according to signal power, to know user moved path and user next moving path. Also, it can be used in entrance authentication system in security area by using tag ID value which stored to backend server.
