The decline in the price of IT devices and the development of the Internet have created a new field called Internet of Things (IoT). IoT, which creates new services by connecting all the objects that are in everyday life to the Internet, is pioneering new forms of business that have not been seen before in combination with Big Data. The prospect of IoT can be said to be unlimited in its utilization. In addition, studies of standardization organizations for smooth connection of these IoT devices are also active. However, there is a part of this study that we overlook. In order to control IoT equipment or acquire information, it is necessary to separately develop interworking issues (IP address, Wi-Fi, Bluetooth, NFC, etc.) and related application software or apps. In order to solve these problems, existing research methods have been conducted on augmented reality using GPS or markers. However, there is a disadvantage in that a separate marker is required and the marker is recognized only in the vicinity. In addition, in the case of a study using a GPS address using a 2D-based camera, it was difficult to implement an active interface because the distance to the target device could not be recognized. In this study, we use 3D Depth recognition camera to be installed on smartphone and calculate the space coordinates automatically by linking the distance measurement and the sensor information of the mobile phone without a separate marker. Coordination inquiry finds equipment of IoT and enables information acquisition and control of corresponding IoT equipment. Therefore, from the user's point of view, it is possible to reduce the burden on the problem of interworking of the IoT equipment and the installation of the app. Furthermore, if this technology is used in the field of public services and smart glasses, it will reduce duplication of investment in software development and increase in public services.

본 논문에서는 블록체인 및 암호화폐(토큰)를 이용해 미디어사물인터넷 내 카메라로부터의 비디오 스트리밍 서비스를 제공하는 시스템을 제안한다. 사용자가 분산형 애플리케이션을 통해 블록체인 상에 작성되어 있는 스마트 컨트랙트의 계약조건에 따라 토큰을 지불하고, 토큰을 지불 받은 IP 카메라는 촬영하고 있는 동영상을 실시간으로 사용자에게 스트리밍하는 시나리오를 구성하였다. 블록체인 카메라 스트리밍 서비스의 가능성을 알아보기 위해, 이더리움 기반의 블록체인 위에 스트리밍 서비스를 위한 스마트 컨트랙트를 업로드하고, 거래에 필요한 ERC20 토큰을 제작하여 시스템을 구현하였다.

In this paper We focuses on suggestion to quality model for IoT infrastructure services for Internet of Things. Quality model is suggested on security set out in ISO25000 quality factors and assessment of the existing traditional software application of ISO 9126 quality model. We validated that the proposed model can be realized it was applied to evaluate the 4 elements and related security in Metrics.

지난 1990년대에는 월드와이드웹 (WWW)이 화투였고, 2000년대에는 모바일 인터넷이 화두였다면, 2010년대는 모든 사물이 네트워크에 연결되는 Internet of Things(이하 IoT)의 세상이 될 것으로 전망되고 있다. 지난 2005년에 발간된 ITU 보고서에 따르면, IoT가 식별자(부착하는 사물)와 센서 및 무선 센서 네크워크(감지하는 사물), 임베디드 시스템(생각하는 사물), 나노공학(수축하는 사물) 분야의 기술 발전을 통하여 감각뿐 아니라 지능적 형태로 전 세계의 모든 사물 및 객체가 상호 연결될 것이라 주장하며, 이에 대한 준비와 대비가 필요하다고 언급한 바 있다. 또한, 본 보고서는 IoT 실현을 위한 가장 중요한 도전으로 표준화와 협력, 프라이버시, 사회 도덕적 이슈에 대한 철저한 대응이 될 것이라 직시한 바 있다. 이제 우리가 살아가는 세상은 또 다른 새로운 변화에 직면하고 있는 것이다. 현재 전 세계에는 15억 대의 PC와 10억 대의 휴대폰이 인터넷에 연결되어 있으며, 향후 2020년까지 약 500억 대에서 1,000억 대의 장치가 인터넷에 접속하는 IoT 세상으로 전환될 것으로 예측하고 있다. 더욱이, M2M 통신뿐만 아니라 객체 사이 통신까지 포함한다면 인터넷에 연결되는 잠재적 객체의 수는 100조 개에 달할 것이라고 한다. 최근 우리나라에서도 사물지능통신이란 용어가 자주 회자되고 있다. 사물지능통신을 광의의 의미에서 해석하면 IoT로 일컬을 수 있을 것이며, 다만, 협의의 의미로 해석한다면, M2M 통신을 지칭하는 것이 맞는 해석이라고 생각된다. 이에 본 특집에서는 사물지능통신 기술에 대한 현황 및 정책, 앞으로의 서비스 전망, 나아가 표준화 추진 동향 등에 대해 살펴보고 앞으로 다가올 미래 디지털 ICT 사회 변화를 조명해 보고자 한다.

Recently, IoT has been supported by ICT technology with a variety of ICT powers. In May 2014, Information and Communication Strategy Committee announced the 'Basic plan for Internet of Things'. Also on Febuary 24 this SAME year, KISA(Korea Internet&Security Agency) provides many projects related to IoT, such as announcement of 'K-Global Project' for start-up and venture support related to IoT and ICT companies. In contrast to the various services of Internet of Things, when a connection is made between object-to-object or person-to-object wired and wireless networks, security threats have occurred in the process of communication. We analyzed these kinds of security threats related to Internet of things, and gave a consideration for requirement.

In IoT environment, an intelligent agent is an autonomous entity with computing power that interacts with various things for specific purposes without human intervention. Recently, as the development of Internet technology has increased the size of resources and services that intelligent agents can utilize, an environment where intelligent agents can collaborate with each other is needed. To effectively support these changes, a method is needed to provide workspaces where intelligent agents can form various groups and collaborate on them. In this paper, we present TSpace which is an Ethereum-based group workspace for effective collaboration among intelligent agents. In TSpace, intelligent agents in IoT environment can use group service based on the Ethereum blockchain through the developed CoAP/RESTful web service. TSpace also introduces a new mechanism for managing Ethereum wallets of agents accessing group services and for creating Ethereum transactions using them.

A variety of communications are developed and advanced by integration of wireless and wire connections with heterogeneous system. Traditional technologies are mainly focus on information technology based on computer techniques in the field of industry, manufacture and automation fields. As new technologies are developed and enhanced with traditional techniques, a lot of new applications are emerged and merged with existing mechanism and skills. The representative applications are IoT(Internet of Things) services and applications. IoT is breakthrough technologies and one of the innovation industries which are called 4 generation industry revolution. Due to limited resources in IoT such as small memory, low power and computing power, IoT devices are vulnerable and disclosed with security problems. In this paper, we reviewed and analyzed security challenges, threats and requirements under IoT service.
