기존의 CCTV와는 달리 IP Camera는 네트워크에 유선 또는 무선으로 직접 연결되며 IP Camera에 임베디드된 웹 서버를 통하여 서비스를 제공한다. 한 건물 또는 지역 안에는 다수의 IP Camera가 설치될 수 있다. 이때 각 각의 IP Camera에 웹 서버가 존재하기 때문에 웹서버 마다 다른 key를 가지고 관리하게 되어 서버 관리에 있어서 비효율적이다. 또한 단순 ID, Password로 사용자 인증을 하며 별도의 암호화 과정을 거치지 않기 때문에 취약점을 갖는다. 따라서 본 논문에서는 그룹 키를 이용하여 다수의 웹 서버의 키를 관리하고 PKI 암호를 통하여 사용자 인증 및 세션 키를 생성함으로써 위장 공격, 기밀성, 무결성, 재사용 공격 등의 보안 취약점을 강화한다.

National Assembly is a constitutional institution that is required to first consult the will of the people and it should do its effort continuously so that security of citizens using parking lot would be enhanced at the same time while improving parking service in order to increase customer satisfaction of the people. Under this recognition, in this study, Doonchi parking lot of National Assembly under consigned management was first reviewed in a perspective of criminal prevention through environmental design(CPTED) and particularly, fence installation and reinforcement work for securing 'territoriality' and operation of all round shooting camera and installation of No-trespassing warning board at entrance were suggested. Second, it was recommended to change independent control system in which CCTV security system of National Assembly Doonchi parking lot is operated separately from National Assembly safety situation room and integrate it with National Assembly safety situation room(revised to double safety system) and performance of CCTV camera was made to be increased to over 2m. In addition, video recording mode was converted to NVR mode for application to IP camera in the future and in order to avoid dead zone of security monitoring area and based on site inspection result, addition 3 places of newly installing CCTV were indicated. Third, it was recommended to introduce parking fare billing and management system through unmanned equipment in parking lot management and operation.(specialized management of professional parking service provider was reviewed). By doing so, risk of cash handling by charging personnel was removed by reducing current 7 working personnel to 3 and particularly, by converting parking lot management mode being operated temporarily from 9 A.M. to 9 P.M. at present to 24 hours operation mode and providing more specialized parking service, citizens visiting National Assembly were provided with convenience and image of National Assembly was also enhanced. This study was carried out in parallel with various literature and case studies, including data from the Office of the Defense Protection in the National Assembly.

현재 정부기관이나 은행 등과 같이 침입 탐지의 보안 서비스를 필요로 하는 곳에서는 주로 CCTV(Closed Circuit TV)와 DVR(Digital Video Recording)과 같은 보안 장비들이 사용되고 있다. 하지만 이러한 장비들은 고가이므로 일반 가정이나 소규모 사업장에 이를 도입하는 것은 어렵다. 이에 본 논문에서는 CCTV나 DVR과 같은 고가의 보안 장비를 저렴하게 대체할 수 있는 인터넷 카메라를 이용한 침입탐지 시스템인 IDS(Intrusion Detection System)를 설계 및 구현하였다. IDS는 침입 탐지 보안 시스템이 기본적으로 갖춰야 하는 모니터링, 녹화, 재생. 침입 탐지 등의 기능을 제공할 뿐만 아니라 인터넷을 이용하므로 거리상의 제약점을 극복하였으며, TCP/IP를 이용한 인터넷 카메라를 사용하여 CCTV나 DVR보다 매우 저렴하게 설치 가능하다.

In order to activate the digital broadcasting in Korea, the analog broadcasting will have been closed down until 2012. Recently IPTV(Internet Protocol TV) thorough internet has been regarded as the fourth media following the terrestrial, satellite, and cable for the digital broad casting. And it has been the important medium for the communication and broadcasting system. However IP is not easy to replace the entire broadcasting system with the digital - type broadcasting system. For the digital broadcasting, we should replace all TV sets, install the settop-boxes to receive the various IP media, solve problems about time delaying when changing channels, and support communication and broadcasting consolidation service for such as PVR and Network CCTV. IPMG is the digital converter that is able to solve these problems. In this paper, I'll develop and analyze IPMG converter's performance which sends and receives both the analogue and digital broadcasting signals through various media gives the Network PVR service.

License plate recognition camera is dedicated device designed for acquiring images of the target vehicle for recognizing letters and numbers in a license plate. Mostly, it is used as a part of the system combined with server and image analysis module rather than as a single use. However, building a system for vehicle license plate recognition is costly because it is required to construct a facility with a server providing the management and analysis of the captured images and an image analysis module providing the extraction of numbers and characters and recognition of the vehicle's plate. In this study, we would like to develop an embedded type convergent camera (Edge Base) which can expand the function of the camera to not only the license plate recognition but also the security CCTV function together and to perform two functions within the camera. This embedded type convergence camera equipped with a high resolution 4K IP camera for clear image acquisition and fast data transmission extracted license plate area by applying YOLO, a deep learning software for multi object recognition based on open source neural network algorithm and detected number and characters of the plate and verified the detection accuracy and recognition accuracy and confirmed that this camera can perform CCTV security function and vehicle number plate recognition function successfully.
