In this research, we describe a security robot system and ongoing research results to control human's wrong direction in order to forbid human to enter security zone. Proposed robot system surveils a security area with equipped laserscanner sensor usually. When it detect walking human who is for the area, robot calculates his velocity vector, plans own path to forestall and interrupts him who want to head restricted area and starts to move along the estimated trajectory. The walking human is assumed to be a point-object and projected onto an scanning plane to form a geometrical constraint equation that provides position data of the human based on the kinematics of the mobile robot. While moving the robot continues these processes for adapting change of situation. After arriving at an opposite position human's walking direction, the robot advises him not to be headed more and change his course. The experimental results of estimating and tracking of the human in the wrong direction with the mobile robot are presented.

Most of access control systems for underground utility tunnel work through wired network between central system and the automatic switch control unit. However, there are several issues regarding the absence of network infrastructure and an outdoor reader in a relatively unique environment. To solve these issues we propose an authenticated key based smart phone control system for secure access to the underground utility tunnel and this scheme is anticipated providing us with crucial information about a systemic entrance history and effective management procedures of utility tunnel. In addition, the proposed scheme enables to access to secured control system in smart phone based bluetooth network and it provides information about systemic control and history management for the switch controls through smart phone applications.

Network Access Control System that is one of the efforts to protect the information of internal applies to effectively control of insider and automatic network management and security. However, it has some problems : spoofing the authorized PC or mobile devices, connect to the internal network using a system that authorized users are away. In addition, information leakage due to malicious code in the same system. So in this paper, Network 2-Factor Access Control System based on RFID security control system is proposed for safety communication environment that performing a two-factor authentication using authorized user and devices to connect to the internal network.

Under the physical records management system, both the records and users could be controlled and secured by closing the door of Archives or using permitted records which is used only approved users. According to the electronic records management system and the concept of service on the basis of users, we have to give up the classical manner. As an alternative, we have to consider the electronic access control system. To accomplish this purpose, functional requirements of ERMS that is issued by UK, EU, U.S and Australia must be compared and analyzed. On the basis of U.K ERMS which is more detailed, 'common access control functional requirements' are arranged. As the access control functional requirements is applied in the records classification scheme, we could find out how the access control is executed in ERMS.

Information society in recent times, lots of important information have been stored in information systems. In this situation, unauthorized person can obtains important information by piggy-backing and shoulder surfing in specific area of organization. Therefore, in this study, we proposed network group access control system by combining RFID and infrared-ray for blocking information leakage due to unauthorized access by internal threats and enhancing personnel security. So it can provides a more secure internal network environment.

[그림1]은 신체적 특징(Physiological biometrics)과 행동적 특징(Behavioral biometrics)을 이용한 사용자 인증기술인 바이오인식기술의 유형과 함께 각 기술별 보안취약점(괄호 안 빨강색글자)을 나타내고 있다. 최근 들어, 모바일 지급결제서비스 ATM 인출기 인터넷전문은행 등과 같은 핀테크 분야에서 비대면 인증기술로 바이오인식기술이 각광을 받기 시작했다. 한편, 가짜지문 등 기존의 신체적 특징을 이용한 바이오인식기술의 위변조 위협에 대한 우려 존재함에 따라 뇌파 심전도 근전도 맥박 등 살아있는 사람의 행동적(신체의 기능적) 특징을 이용한 생체신호를 이용하여 비대면 인증기술로서 활용하기 위하여 주요 선진국에서 차세대 바이오인식 기술개발이 가속화되고 있는 추세이다.[1] 또한, 이러한 생체신호는 최근에 삼성전자, LG전자, 애플 등에서 스마트워치를 통해 심장박동수를 측정하고 스마트폰을 통하여 모바일 지급결제, 헬스케어 등과 같은 IoT 모바일 융복합 응용서비스에 활용될 전망이다. 본고에서는 뇌파 심전도(심박수)와 같은 생체신호를 측정하는 스마트워치 밴드형 의복형 또는 패치형태의 웨어러블 디바이스와 같은 생체신호센서, 생체신호 인증기술 및 관련표준화 동향을 고찰해 보기로 한다. 국내외 관련기술과 표준화 동향을 면밀히 분석하여 지난 2015년 5월29일에 발족한 국내외 전문가그룹인 KISA"모바일 생체신호 인증기술 표준연구회"(이하 KISA 표준연구회)가 구심점이 되어 한국형 생체신호를 이용한 차세대 텔레바이오인식기술에 대한 연구개발과 국내외 표준화 추진에 박차를 가할 계획이다.

본 논문은 COVID-19 유증상자를 사전에 판별해 유증상자의 시설 출입을 제한하고, 비접촉 인증 방식인 RFID, 얼굴인식을 사용해 시설 내 COVID-19 집단 감염을 예방하는 시설 관리 스마트 도어록을 제안한다. 기존 디지털 도어록 및 스마트 도어록은 가정용으로 개발되어 많은 사람이 이용하는 다중 시설에서 사용하기에 불편하다. 본 연구에서 구현한 도어록은 아두이노 센서를 통해 시설 사용자의 체온과 산소 포화도 값을 받아 사용자의 COVID-19 증상 유무를 판단한다. 유증상자의 경우 경고음을 울려 시설 출입을 사전에 제한한다. 체온과 산소포화도 측정 후 비접촉 인증 방식인 RFID, 얼굴인식을 통해 시설 출입을 통제한다. 시설 관리자는 RFID, 얼굴인식, 도어록 전용 애플리케이션을 사용해 시설에 출입할 수 있다. 본 시스템을 통해 시설 관리가 편리해지고, 증가하고 있는 스마트 빌딩 및 무인 시설에 활용할 수 있다.

WHO declared a global pandemic on March 11th for Corona 19. However, there is a situation where you have to go to building for face-to-face education or seminars for economic and social activities. The first check method of COVID-19 infection is to measure body temperature, so the primary entrance and exit is blocked for near-field body temperature measurement. However, since it is troublesome to check directly, thermal camera is installed at the entrance of the building, and body temperature is measured indirectly using the infrared camera to control access. In case of middle and high schools, universities, and lifelong education center, we need a system that is possible to interoperate with attendance checks and automatically recognizes whether to wear masks and can authenticate students. We proposed the system that is to confirm whether to wear a mask with a camera that is embedded in a smart mirror, and that authenticates the user through voice recognition of the user who wants to enter the building by using voice recognition technology and determines whether to enter them or not. The proposed system can check attendance if it is linked with near-field temperature measurement and attendance check APP of student's smart phone.

In addition to complying with access standards for facilities that require infection control (operating rooms, delivery rooms, intensive care units, etc.) in accordance with the 2019 Medical Care Act Enforcement Regulations, entry, exit, contact information, etc. for entry and exit, the criteria for entering and exiting special rooms of medical institutions have been revised so that records of facts are kept for one year. However, even now, the inconvenience continues due to the fact that such contents are created by hand or due to errors. For this reason, this study designed and implemented a system that provides automatic opening, closing, and accessing record storage functions for authorized users using IoT devices and UWB technology, and we expected that the convenience of the visitors and systemized access control will be possible.
