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.

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.

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.

정보통신의 발달로 인하여 사물간의 필요한 모든 정보를 상호작용하는 IoT(Internet of Thing)환경이 발전하고 있다. 홈 IoT환경에서는 스마트폰 어플리케이션을 통하여 집안 내부를 살펴보고 외부 침입자가 들어오면 이를 감지, 신고할 수 있는 IP Camera의 수요가 증가되고 있다. 그러나 IP Camera의 해킹 사례가 증가 하고 있고 취약한 인증, 잠재적인 공격 가능성 등 보안문제가 발견되었다. 이에 본 논문에서는 대중적으로 많이 사용되고 있는 IP Camera와 Smart Phone과의 안전한 사용자 인증 프로토콜을 제안하였다.

Development of Internet technology and the spread of various smart devices provide a convenient computing environment for people, which is becoming common thanks to the Internet of Things (IoT). However, attacks by hackers have caused various problems, such as leaking personal information or violating privacy. In the IoT environment, various smart devices are connected, and network attacks that are used in the PC environment are occurring frequently in the IoT. In fact, security incidents such as conducting DDoS attacks by hacking IP cameras, leaking personal information, and monitoring unspecified numbers of personal files without consent are occurring. Although attacks in the existing Internet environment are PC-oriented, we can now confirm that smart devices such as IP cameras and tablets can be targets of network attacks. Through performance evaluation, the proposed protocol shows 11% more energy efficiency on servers than RSA, eight times greater energy efficiency on clients than Kerberos, and increased efficiency as the number of devices increases. In addition, it is possible to respond to a variety of security threats that might occur against the network. It is expected that efficient operations will be possible if the proposed protocol is applied to the IoT environment.

In this paper, we propose a system that uses image data and beacon data to classify authorized and unauthorized perosn who are allowed to enter a group facility. The image data collected through the IP camera uses YOLOv4 to extract a person object, and collects beacon signal data (UUID, RSSI) through an application to compose a fingerprinting-based radio map. Beacon extracts user location data after CNN-LSTM-based learning in order to improve location accuracy by supplementing signal instability. As a result of this paper, it showed an accuracy of 93.47%. In the future, it can be expected to fusion with the access authentication process such as QR code that has been used due to the COVID-19, track people who haven't through the authentication process.

There is increasing concern about security as a need for increased safety in the information industry society. However, it does not meet the needs for safety including CCTV. Therefore, in this paper, we link the processing technology using the image information to the IPS system consisting of GPS and Beacon. It designed a conventional RFID tag attached discomfort and image tracking system is limited to complement the disadvantages identifiable area. To this end, we designed a smart device and the Internet of Things convergence system and a research to ensure the accuracy and reliability of the IPS of the access control system. Finally, by leveraging intelligent video information using a PTZ camera, and set the entrant management policies it was carried out to control the situation and control. Also, by designing the integrated video tracking system, an authentication server, visualization systems were designed to establish an efficient technique for analyzing the IPS entrant behavior patterns.
