Recently, the smart devices has been possessed by a large majority of the adult, and offered various personalization services. This paper proposed the lightweight Intelligent Image Security System that notice the existence of any intruder in real time at the place of requiring the security by using smart device. The proposed image security system recognized whether or not intruder exists using the difference frame on the basis of Integral Image and the dynamic background updating algorithms. The intrusion notification is achieved by using the GCM push server that send massages in the application unit of user mobile device, and the SMTP mail server which is use of e-mail standard protocol. In case of the occurrence of intruder, GCM push server send an push-massage by the private mobile device, and SMTP mail server send the intruder's photograph and intrusion time. By the convergence of the various image processing algorithms and the performance of smart device, The proposed image security system can be applied to the various Intelligent Image Security field.

Recently, new types of security crimes have been steadily occurring in Korea due to environmental changes such as the development of IT technology, and responding to these threats has become a key national task for the establishment of a safe society as well as individuals and businesses. Meanwhile, as the Zero-Contact Era has arrived since the COVID-19 Pandemics, a new convergence security threat that combines the characteristics of the Zero-Contact Era with the existing IT development is threatening our society. Research to prevent and correct these new levels of threats is continuously required in this study. Chapter 1 examined the causes of new convergence security threats and Chapter 2 discussed cybersecurity, fake news, remote voting·work and video security threats as five major threats.

본 논문은 기존의 웨어러블 센서 방식이 아닌 영상으로 반려견의 행동을 분석하는 연구에 대한 것이다. 제안한 시스템은 영상에서 반려견의 영역을 탐지하고, 탐지된 이미지에서 반려견의 관절 좌표를 추출하여 행동을 판단하는 방식이다. 모든 프레임에 대해 처리하지 않고, 일정 주기 단위로 영상을 처리해 실시간성을 확보하였다. 제안한 시스템의 유용성은 실험으로 검증하였으며, 유의미한 실험 결과를 얻을 수 있었다.

Due to the development and market expansion of image analysis and recognition technology, video security such as CCTV cameras and digital storage devices, are required for real-time monitoring systems and intelligent video security systems. This includes the development of more advanced technologies. A rotatable PTZ camera, in a CCTV camera system, has a zoom function so you can acquire a precise picture. However it can cause blind spots, and can not monitor two or more moving objects at the same time. This study concerns, the intelligent tracking of multiple moving objects, CCTV systems, and methods of video surveillance. An intelligent video surveillance system is proposed. It can accurately shoot broad areas and track multiple objects at the same time, much more effectively than using one fixed camera for an entire area or two or more PTZ cameras.

기존 아날로그 방식의 CCTV는 화질이 좋지 않고, 장시간 사용할 경우 화질이 나빠지는 문제가 발생한다. 이와 같은 문제를 해결하기 위해 아날로그 신호출력을 디지털 방식으로 변환하는 DVR과 IP 네트워크로부터 디지털 신호를 받아 처리하는 NVR이 등장하게 되었다. 이와 같은 영상 보안 이슈가 등장함에도 불구하고 보안 산업 보수성과 새로운 기술을 받아들이는데 있어서의 제약사항 등의 이유로 IP-Suveillance에 대한 이해가 부족한 실정이다. 따라서 본 논문에서는 영상보안 시스템의 동향과 분석을 위해 DVR과 NVR을 투자측면, 비용측면, 유지측면에서 비교 분석하였다.

In case of security of IoT-based areas in ICBM industry, the anxiety about safety goes to extremes in public and national safety area, so that the demand for security service related to disaster/safety management is increasing. Like this, as a security service for safety, CCTVs are installed/operated for the purpose of maintenance of public order and crime prevention. Especially, as the recorded images are presented as crucial evidences of crimes, they are rapidly increasing. However, as adverse effects of CCTVs, it is highly possible to unintentionally leak personal information in the process of performing the original purpose, or to violate someone's privacy in case when such technologies are abused. Therefore, it would be necessary to have researches on the multilaterally-combined mechanism for the protection of image privacy.

In this paper, implementation of a wireless video security system relates to a situation outside of using infrared sensors to detect changes when using Zigbee network security in the area of the sensor sends information to the server. The server can judge the situation if an emergency situation through the IP network security camera shot of the area to be transferred command to pantilte. The camera images and information in the security area, sent to administrator's smartphone users to control the camera can see the situation and More than a small video security system was designed so that user can monitor the security zone. Finally, for real-time to identify and respond to emergency situations based on the available wireless networks for video surveillance systems were verified through research and implementation.

In visual surveillance system abandoned objects in public places are the deliberately left things, which should be automatically detected by intelligent systems in the environment where the number of cameras is increasing. This research deals with the design scheme of a smart security disk system which can detect these abandoned objects automatically and save the relevant image information with the wireless interface of high definition images. By implementing the proposed system in this research it is confirmed that the transmission performance shows 60 frames per second without compression of high definition images and the capability of the disk system shows the relevant images can be saved in a RAID configuration. Also, the proposed visual surveillance software shows a good detection rate of 80% in PAT performance.

In this paper, an efficient implementation of AES encryption algorithm is presented for CCTV image security using C# language. In this approach, an efficient S-Box is first designed for reducing the computation time which is required in each round process of AES algorithm, and then an CCTV image security system is implemented on the basis of this algorithm on a composite field GF(((22)2)2). In addition, the shared S-Box structure is designed for realizing the minimized memory space, which is used in each round transformation and key scheduling processes. Through performance evaluation, it was confirmed that the proposed method is more efficient than the existing method. The proposed CCTV system in C# language using Visual studio 2010.
