In order to realize a smart home, a new type of service that converges the two technologies is required as a method to overcome the respective limitations of augmented reality and IoT technologies. Augmented reality recognizes objects and projects augmented content with the recognized objects on the screen. This technology mainly uses image processing methods such as markers as a method for recognizing objects. In this paper, an augmented reality-based IoT control platform using markers was developed. By defining a marker unique to the object, a unique identifier displayed on the camera was distinguished. A smart home system was implemented by calling a controller to control things. The proposed system receives state information of objects through symptom reality and transmits control commands. The proposed platform was verified by manipulating household lights.

IoT(Internet of Things) has become a major issue as new type of convergence technology, expending existing of USNs(Ubiquitous Sensor Networks), NFC(Near Field Communication), and M2M(Machine to Machine). The IoT technology defines as a networking for things, which can establish intelligent links collaboratively for sensing networking and processing between each other without human intervention. The purpose of this study is to investigate to forecast the future distribution changes and orientation of contribution of distribution industry on IoT and to provide the implication of distribution changes. To become a global market leader, IoT requires much more development of core technology of IoT for distribution industry, new service creation and try to use a market-based demand side strategy to create markets. So, to become a global leader in distribution industry, this study results show that first of all establishment of standardization of IoT, privacy safeguards, security issues, stability and value were more important than others. The research findings suggest that the development goals of IoT should strive to boost the creation of a global leader in distribution industry and convenience to consider consumers' demands as the most important thing.

4차 산업혁명 시대가 빠르게 다가오고 있다. 사물인터넷(IoT)과 인공지능(AI), 자율주행 자동차, 로봇, 드론, 스마트 홈 등이 그것. 4차 산업혁명의 핵심 기술 중 하나는 지능형 첨단센서다. 이 '똑똑한' 센서들 없이는 인공지능도 사물인터넷도 불가능했을 것이다. 첨단 센서 기술이 4차 산업혁명의 기폭제 역할을 하는 셈이다.

In this paper, we propose the terminal authentication system using blockchain and TOTP(Time-based One-time Password Algorithm) to sustain a continuous authentication between user device and service device. And we experiment this system by using door-lock as a terminal of IoT(Internet of Things). In the future, we can apply this result to several devices of IoT for convenience and security. Although IoT devices frequently used everyday require convenience and security at the same time, it is difficult for IoT devices having features of the low-capacity and light-weight to apply the existing authentication technology requiring a high amount of computation. Blockchain technology having security and integrity have been used as a storage platform, but its authentication cannot be performed when the terminal cannot access any network. We show the method to solve this problem using Blockchain and TOPT.

Things Internet technology is rapidly becoming a reality in many parts of our lives through various product services. As the perception of Internet services for things has become more common and the intention to purchase Internet devices has begun to increase, various Internet devices have appeared and the need for a server to control them has been emphasized. In addition, IFTTT, a representative Internet automation service platform, is continuously diversifying related services such as home appliances, light bulbs, and smart homes, and has a variety of Internet information such as weather information and news, which can be utilized through IFTTT. And MQTT, which is designed for use in low-power, low-bandwidth environments. This paper implements a server for controlling and managing Internet devices and related services based on IFTTT and MQTT.

We analyzes representative technologies of IoT patents and reflects these results in the curriculum of IoT. In order to identify the representative technologies, the IPC codes of the patents were analyzed. Among the main category IPC codes, the most used IPC codes were H04L in Single IPC Patent with 974 cases(32.0%) and G06Q in Multiple IPC Patent with 710 cases(29.2%). As a result of classifying the IPC code into the WIPO technology classification system, the most emphasized technologies are Digital Communication, accounting for about 60.5% in the Single IPC Patent and IT Methods for Management(710 cases, 29.2%) in Multiple IPC Patent. The main points to be considered when organizing the curriculum of IoT are: ∇Emphasis on Digital Communication, ∇Expansion of Education related to IT Methods for Management(Including entrepreneurship and patent application), and ∇Consideration of subjects related to the Convergence of IoT. This research can contribute to the curriculum design of new industrial technologies such as AI and Fintech.

최근 사물인터넷(IoT, Internet of Things)관련 기술의 발전 및 서비스 산업의 급속한 발전으로 센서 장치에 대한 수요가 증가하고 있다. 센서 장치는 사물인터넷 플랫폼과의 연동을 위한 통신 인터페이스를 필수로 지원하여야 하며, 그 외에 다양한 센서들의 연동 인터페이스와 소비 전력을 모두 고려하여 하드웨어 및 소프트웨어의 설계가 이루어져야 한다. 이와 같이 센서 장치는 베터리 소비를 최적화하여 모든 기능이 구현되어야 하므로 기능상의 제약이 많이 따른다. 시간 동기화를 위해 사물인터넷 플랫폼에서 송신하는 동기 메시지를 수신하기 위해 슬립모드를 지원하는 경우 센서 장치가 항상 깨어 있어 야하므로 저전력으로 동작 할 수 없는 어려움이 따른다. 따라서 사물인터넷망에서 시간동기화를 위한 마스터 클럭을 선정 방법을 제안하고 이를 위한 단일 프레임 방식을 제안한다. 향후 시간 동기화 프로토콜의 호환을 위해 CoAP 규격과 연동 될 수 있는 연구가 필요하다.
