  • The purpose of this paper is to improve the authentication method for IP camera user authentication. Since existing authentication uses knowledge-based authentication method, if ID and PW are exposed to attack by attacker, IP camera becomes defenseless from attacker. The attacker can access the IP Camera and acquire and distribute real time video and voice, which can be exploited as a second crime, and there is a fear of a secret leak when a secret facility is installed. In order to compensate for this vulnerability, this paper proposes a DUI authentication method that identifies and registers a device using DUI (Device Unique Identifier), blocks access to unauthorized devices by subordinating the device to the IP Camera and authenticates only authorized devices.

  • 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.

  • 본 논문에서는 Wowza Media Server를 이용하여 IP Camera 영상을 스마트폰에 리스트리밍(Re-Streaming) 서비스하는 것을 연구하였다. 기존에 웹에 포함되어 있는 멀티미디어 파일은 서버로부터 다운로드받아 해당 파일을 실행시켰는데 이는 하드웨어 자원 문제와 다운로드 시간문제, 저장 공간을 필요로 하는 단점이 있었다. 이에 비해 스트리밍 서비스는 서버에서 실시간으로 전송되어 바로 재생이 가능하며 별도의 저장 공간을 필요로 하지 않기 때문에 스마트폰과 같은 제한적인 플랫폼에서 사용되기 적절한 서비스이다. IP Camera 영상을 스마트폰으로 스트리밍 하기위해서는 IP Camera의 영상을 Wowza Media Server로 실시간 스트리밍 한 뒤, Wowza Media Server가 이 영상을 다시 스트리밍서비스하는 리스트리밍(Re-Streaming)기법을 이용한다. 또한 VLC Player를 사용하여 IP Camera의 영상을 각기 다른 스마트폰 환경에 최적화된 영상으로 변환하여 스트리밍 서비스하였다. 이러한 IP Camera영상 스트리밍 서비스는 관공서, 공사장, 가게 등의 상황을 스마트폰으로 실시간 확인하고자 하는 수요를 만족시키기 위해 어플리케이션으로 개발되어 제공될 예정이다.

  • IP camera which transmits image signal in network includes web server, network interface unit and CCD(Charge-Coupled Device) module. IP camera is able to transmit image signals by network in real time and to monitor the scene image always by IP or Web address. IP camera is substituted for analog camera now gradually according to the development and progress of camera technology and expect it to extend the boundary in rolling stock gradually cause of the excellent expansibility and noise solution of analog camera. We survey the IP camera system composition in rolling stock and so this can be a help to develop and design IP camera system, because it has unsolved problems for common use of IP camera.

  • Global companies are building global production network for the demand of the global market. However, the establishment and operation of overseas plants make the unexpected case like theft, low will to produce and salary issue of local workers. Thus in this paper, we propose the raw materials loss prevention model based on IP Camera and RFID Box for raw materials management of overseas plants. This model can prevent the theft or loss of raw materials write inventory up in real-time. This model can be allows us to realize the cost-effective production management because it enables remote inventory management. And this model can prevent brand image danage and profit loss due to reject product.

  • This paper describes a new progressive embedded Internet Protocol(IP) camera available for real-time image transmission. It was applied for ship safety and security on seashore area. The functions of developed embedded system was more effective and excellent than conventional systems. Nowadays, each nation has established harbor security systems to jump up their ports to international port. Recently Incheon port has tried to change man security into center security system used by image security system. The security system of Incheon port has some advantages like effectivity of security system and reduction of manpower and cost, installed by image security system with CCTV cameras at the entrance gate and around the fence. Thus in this paper, we have designed and implemented a Personal Digital Assistants(PDA) based Image Surveillance System for Harbor Security using IP Camera under ubiquitous environment. This system has big advantages which are more effective in an emergency and low cost and small manpower than conventional systems.

  • Currently widely used IP cameras provide the ability to control IP cameras remotely via mobile devices. To do so, the IP camera software is installed on the website specified by the camera manufacturer, and authentication is performed through the password between the IP camera and the mobile device. However, many products currently used do not provide a secure channel between the IP camera and the mobile device, so that all IDs and passwords transmitted between the two parties are exposed. To solve these problems, we propose an authentication and key exchange protocol using ID-based signature scheme. The proposed protocol is characterized in that (1) mutual authentication is performed using ID and password built in IP camera together with ID-based signature, (2) ID and password capable of specifying IP camera are not exposed, (3) provide forward-secrecy using Diffie-Hellman key exchange, and (4) provide security against external attacks as well as an honest-but-curious manufacturer with the master secret key of the ID-based signature.

  • In this paper, we propose the development of high resolution $360^{\circ}$ omnidirectional IP camera with 12 million pixels. The proposed 12-megapixel high-resolution $360^{\circ}$ omnidirectional IP camera consists of a lens unit with $360^{\circ}$ omnidirectional viewing angle and a 12-megapixel high-resolution IP camera unit. The lens section of $360^{\circ}$ omnidirectional viewing angle adopts the isochronous lens design method and the catadioptric facet production method to obtain the image without peripheral distortion which is inevitably generated in the fisheye lens. The 12 megapixel high-resolution IP camera unit consists of a CMOS sensor & ISP unit, a DSP unit, and an I / O unit, and converts the image input to the camera into a digital image to perform image distortion correction, image correction and image compression And then transmits it to the NVR (Network Video Recorder). In order to evaluate the performance of the proposed 12-megapixel high-resolution $360^{\circ}$ omnidirectional IP camera, 12.3 million pixel image efficiency, $360^{\circ}$ omnidirectional lens angle of view, and electromagnetic certification standard were measured.

  • In this paper, we propose a system which can detect the smoke in real time from the high-quality IP camera. For real-time processing, open directly the RTSP streams transmitted from the IP camera using the library FFmpeg as opening a video file. To recognize smoke, color information and morphological characteristics of smoke, as well as the dynamic characteristics of the smoke also considered for candidate regions. To combine the characteristics of the various smoke effectively, the Adaboost algorithm, was used as the boosting algorithm finally. Through the experiments with input videos from IP camera, the proposed algorithms were useful to detect smokes.
