Recently, service based on internet is inter-connected and integrated with a variety of connection. This kind of internet of things consist of heterogenous devices such as sensor node, devices and end-to end equipment which used in conventional protocols and services. The representative system is healthcare system. From healthcare appliance used by IoT, patient and doctor can utilize healthcare information with safety and high speed management. It is very convenient management to operate mobility. But it induced security and vulnerability issues because it has small memory capacity, low power supply and low computing power. This made impossible to implement security algorithm with embedded engine based on hardware. Nowdays, we can't realize conventional standard algorithm due to these kinds of reasons. From the critical issues, it occurred security and vulnerability issues. Therefore, we analysed and compared with conventional method and proposed techniques. Finally, we evaluated security issues and requirement for end-to-end point healthcare system based on internet of things.

In the existing smart home, a separate platform was set up for each manufacturer to provide services through terminals. However, due to the development of Internet technology, various Internet devices and services have been launched, and there is a limit to the existing closed platforms for each manufacturer. Therefore, in this paper, we propose an object internet controller that integrates control of Internet devices in a smart home environment and provides various services through IFTTT. The proposed Internet controller is connected to the server via WiFi, and can control the Internet device and service of objects through the button input event. In addition, we expect to be able to provide a service environment that can create various smart home services by registering DIY products through open platform of oneM2M standard method.

This paper tries to find the implications applied to art institutions of Korea by analyzing what the content and consequences of services of the Cleveland Museum of Art provided after the Internet of Things adoption in the theoretical perspectives strengthening service marketing through the Internet of Things increases visits and participation in the museum. For analysis, journal articles, statistics, and government press releases, news articles, web pages, web page articles are collected. The results are first, the application of digital and social media is positive in visit to the museum and monetization. Second, the introduction of the Internet of Things will enhance the museum's 'Education', 'Accessibility', 'Communications' services, as well as significantly increase on and offline participation by activating experience. Third, technical support from related companies with the support of local government funds is essential to build the system. Consequently, in order to enable the participation of the spectators in the galleries it is proposed aggressive adoption of such digital technology in domestic barren market of Internet of Things.

As the new technologies like IoT and Fintech appear which have not existed before, security threat ranges in existing system are increasing. Especially, IoT has increasing ranges to cause malicious behaviors in specific systems because related IT infrastructure ranges are increasing. Fintech also requires the innovation of traditional security system because it has new structure which didn't exist in the past. As IoT and Fintech technologies are commercialized and related markets are developing in the future, structural security threats could be connected to actual attacks and secondary attacks by the attackers' imbedding of back door in IoT internet devices through remote access. Customer's device cannot be compulsively controlled for security in new system where these various security threats exist. Therefore, these services should minimize the collected information, and now is the time to politically control the utilizing methods of the collected information. In this thesis, security threats are to be suggested which could occur in newly appearing mobile services like IoT and Fintech.

산업제어시스템과 SCADA(Supervisory Control and Data Acquisition) 제어 시스템들이 기존의 고립적이고 폐쇄적인 시스템에서 점차 개방적이고 표준화된 시스템으로 전환되고 있으며, IT 망과의 통합이 이루어지고 있다. 따라서 주요 국가정보 인프라에 대한 사이버 위협 및 공격에 대한 우려가 증대되고 있다. 산업제어시스템의 정보보호 기술은 일반적인 IT 정보보호 기술과는 특성상 여러 가지 차이점이 존재한다. 국내에서의 산업제어시스템 정보보호 기술에 대한 연구는 아직 미약한 수준이다. 본 논문에서는 국가 주요 정보하부구조를 구성하고 있는 산업제어시스템 중에서 사물인터넷(IoT) 기반 스마트 그리드 시스템의 보안 특성에 대하여 분석하고 보안 쟁점 및 고려사항을 제시하고자 한다.

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.

In recent years, the importance of IoT (Internet of Things) is emphasized by information communication technologies and the performance of various smart devices are rapidly developed and applied in the real world. In this paper, we propose a process-driven IoT-object collaboration model to specify and execute a IoT service based on processes. That is, the purpose of this paper is to suggest a formal method in order to describe a IoT service into a group of tasks having execution order and collaboration between IoT-objects in charge of the enactment of a task. Conclusively, through the proposed model, we expect that IoT services will be automatically executed, analyzed, monitored and reused in the process-driven IoT computing environment.

사물인터넷(Internet of Things: IoT)이란 모든 사물이 인터넷에 연결되어 상호 간에 직접 통신하는, 향후 정보통신의 미래 인프라 및 서비스이다. 이것이 필요한 이유는 초연결 사회에 기반을 둔 삶의 질 향상과 생산성 향상에 있으며, 최종적으로는 국가 자체의 인프라, 더 나아가서는 인류를 위한 중추 신경계를 이루기 때문에 무엇보다 중요하다. IoT는 셀룰러 이동통신 기반의 IoT와 비셀룰러기반의 IoT로 대분되어 오다가 두 분야의 융합이 이루어지고 있다. 그러나 IoT는 현재 거품 최고조기에 있으며, 아직까지 주목할 만한 큰 수익모델이 없는 상태이다. 그 이유는 사물인터넷 서비스 활성화에 가장 걸림돌이 되어온 보안문제, 배터리수명, 통신거리, IoT 디바이스를 포함한 솔루션 가격 그리고 월정료 문제가 여전히 존재하기 때문이다. 최근 이들 문제 해결을 목적으로, 대량의 IoT 디바이스를 필요로 하는 새로운 사물인터넷 커넥티비티에 대한 재정의, 표준화 및 솔루션 개발이 핫이슈이다. 본고에서는 셀룰라 및 비셀룰라 IoT기반의 Low Power Wide Area(LPWA), 즉 저전력 광역 IoT에 대한 시장, 기술 및 솔루션 비교 그리고 표준화 동향을 다룬다. 또한, 비셀룰라기반 즉 비면허대역과 프리밴드 활용을 통한 기술적 및 정책적 대응전략을 살펴본다.
