A video information processing system (CCTV) requires comprehensive administrative, physical, and technical security management to collect, transmit and store sensitive information. However, there are no regulations related to video information processing, certification methods for the technology used, and application standards suitable for security technology. In this paper, we propose a cryptography, certification, protection, system (CCPS) model that can protect the system by including encryption technology for application to the video information processing system and authentication measures for the technology used in the system configuration.

It is said that we live in an age of technology. And indeed, science and technology do play key roles to our life of happiness, but they are equally central in all events that threaten it. Science and technology are the means we often turn to in seeking solutions to our problems, and in turn are often the apparent sources of new problems. Thus it is not surprising that they have two aspects at the same time. CCTV has been presented to us as a technical solution to security problems. With the help of CCTV, we can more effectively prevent, detect, and prosecute crimes. With the help of CCTV, both public and private spaces can be made more secure. But of course, CCTV also has a down side. The down side most prominently anticipated has been loss of privacy and proliferation of surveillance. It is largely this potential problem with CCTV that has been regulated against. It is said that one reason for imposing a limitation on individual privacy is the societal interest in the prevention of crime. Accordingly a balance between the need to prevent crime through the use of CCTV and the duty to respect the privacy interests of individual citizens is in need of redress. In other hand, two theories of socio-political philosophy may have provided useful ways of understanding the role of CCTV in contemporary society. Firstly, neo-Marxist frameworks, for instance, stress the use of CCTV to police existing unequal socioeconomic divisions within society and the dominance of particular forms of order based upon materialist agendas. Secondly, Foucauldian frameworks contend that Foucault's notion of panoptic surveillance underpinning (self) disciplinary society is an appropriate template for understanding CCTV in late-modern society. In order to find a new point of valance between security and privacy in the use of CCTV, the participation of each citizen in the discourse to make the new norm is necessary. And to prevent its political misuse, their surveillance, or check for the potential surveillance-power is required.

Arrest effect of CCTV for crime prevention is very important. CCTV for crime prevention is evaluated as the tools that act efficiently in terms of criminal arrest because CCTV is used later as evidence acting as the eyes of the distance in deserted place. Necessity of CCTV is increasing gradually because of the advantages that obtaining evidence and criminal found arrest is easy. But quality of CCTV is bad and Night Recording is poor. So it is necessary to improve quality of CCTV and Night Recording should be possible for using as crime clues and evidence. In addition, through integrated building control systems of CCTV for crime prevention and extension of retention period it is possible to easily obtain a evidence.

Recently, people in cities of developed countries are exposed to unfortified damages of crime and disaster due to urbanization, industrialization and information-oriented era caused by congestion of population in terms of hardware and various social pathology phenomena and frequent and large scale of disaster caused by crime and disorder, which occur in the course of going through nuclear family, a gap between rich and poor and aging society in terms of software. In this regard, demand for security upon individual life and property has been increased but the police that are responsible for the public security does not effectively reduce damage in life and property because their activities are mainly oriented in coping with security accidents more than prevention. Shortage of manpower and budget, retarded equipment, and heavy overwork are the reasons. In order to confront with this kind of situation, we should utilize CCTV system with the purpose of declining possible chances of crime, not for eliminating cause of crime as crime prevention activities to predict danger in advance as a way of prevention and we may expect a role of damage prevention by installing CCTV in places where security accident may possibly happen. In conclusion, there are invasion of privacy, misuse of the system, insufficiency of overall monitoring office management, lack of citizens' understanding and economical allotment of the system installation costs in installation of CCTV system. However. it is necessary to install the CCTV system for effective prevention of crime and prevention activities of security accidents and accurate PR of purposes of installing CCTV to local residents, establishing relevant laws about system misuse, allotment of equipment costs and fees by R&D of the system machinery, cost reduction method of storage, management and replacement, saving costs from co-operative attitude of government, and local autonomous entities and local residents should be involved.

There are so many CCTV in our streets, buildings and public places. Nevertheless, security methods for CCTV are rarely. This paper describes a study on developing a media crypto algorithm for anti-hacking into CCTV. H.264 codec is used to compress the video stream in CCTV systems. HIGHT algorithm provided by KISA is adopted as a crypto algorithm in our development. Other crypto methods except HIGHT could be selected by company's security police. Only some bytes in VCL(Video Coding Layer) of H.264 are encrypted to improve the performance of limited platforms, such as CCTV, WebCam, smartphone. Very fast and light crypto algorithm was developed by our researches.

최근 사물인터넷의 발전에 따른 많은 기기들이 디지털화 되면서 네트워크의 새로운 주요 장비로 등장하고 있으며 이 중 CCTV의 경우 대부분 IP를 갖는 독립적인 네트워크 디바이스가 되고 있다. 하지만 이러한 CCTV의 네트워크 접근에 따른 해킹 가능성이 끊임없이 제공되면서 CCTV를 통한 내부망의 침투가 현실적으로 가능한 상황이다. 현재 대부분의 영상 화면이 암호화되어 운영되고는 있지만 CCTV를 통제하는 제어 데이터는 어떠한 보안조치도 이루어지지 않은 것이 현실이다. 이러한 점을 보완하기 위해 면에서 본 논문에서는 CCTV 통제를 위한 제어 데이터도 인증 및 암호화를 통해 일반적인 접근을 완전히 차단할 수 있는 방안을 제시하고 이를 통한 사물인터넷의 안정성을 검증하는 방안을 제안하고자 한다.

Recently CCTV system is installed widely purpose to enhanced physical security, gathering criminal evidence and management of facilities. In spite of supporting strong management function, CCTV system has weak security function. Therefore high security management function is required. Generally it's not easy to control the devices under NAT using a NMS(Network Management System). So we design and implement alive check algorithm of CCTV devices under NAT using DVRNS address resolution and TCP session check. We evaluated and analyzed of developed system on real environment which includes about 100 DVRs under NAT. As a result of test, it showed that device alive check and DVRNS address resolution were well performed without any error.

시대가 발전함에 따라 기술도 발달하지만 시민의식이 따라가지 못하기 때문에 그 만큼 범죄도 늘어나고 있다. 그럼에 따라 범죄를 예방하기 위해 방범용 CCTV를 늘리고 있는 추세이다. 그러나 방범용 CCTV를 늘리기 위해서는 많은 시간과 예산이 필요하다. 그래서 사용자들은 불법 주정차 시스템에 방범 기능을 요구하고 있는 추세이다. 그러나 기존의 CCTV는 화소가 낮아 이미지가 선명하지 않기 때문에 방범 기능에 적용하기에는 미흡한 점이 많았다. 그래서 본 논문에는 기존의 시스템을 보완하기 위한 방안으로 메가 픽셀을 적용하여 불법 주정차 시스템의 방범 기능을 향상 시킬 수 있는 방안을 제안하였다. 결과적으로 저화질 CCTV를 사용 할 때보다 불법 주정차 단속뿐만 이라 방범 시스템으로도 더 나은 효과를 보일 것으로 예상한다.

CCTV(Closed Circuit television) is one of the widely used physical security technologies and video acquisition device installed at specific point with various purposes. Recently, as the CCTV capabilities improve, facial recognition from the information collected from CCTV video is under development. However, in case these technologies are exploited, concerns on major privacy infringement are high. Especially, a computer connected to a particular space images taken by the camera in real time over the Internet has emerged to show information services. In the privacy law, safety measures which is related with biometric template are notified. Accordingly, in this paper, for the protection of privacy video information in the video surveillance system, the technical and managerial requirements for video information security are suggested.
