As the existing face recognition CCTV and home IOT have each individual hardware component, they have a disadvantage that the measured results of their sensors and the CCTV can not be viewed on one screen at a time. In order to overcome the above disadvantages of existing CCTV and home IOT, this paper proposes an integrated platform which constitutes the CCTV and home IOT as one hardware component using Raspberry Pi and shows each result on one screen through Smartphone application. The proposed integrated platform CCTV and home IOT system is a system which can run the application as a Smartphone and check the sensor value measured by Raspberry Pi and the picture taken through the Pi camera. The implemented system measures temperature, humidity, gas, and dust, and implements face recognition technology on a screen shot through a Pi camera, allowing it to be seen at a glance with a Smartphone.

In this paper, we propose a methodology to deal with the IOT system gradually as the use of effective systems such as electronic devices, healthcare, smart cars, smart home, remote meter reading and telemedicine closely related to our real life in the IOT system An IOT integrated account solution is needed as a way to address these needs as the demand grows for the need to identify and manage how users access and use the system for what period of time and at what point in time. We propose the communication algorithms for endpoint system, IOT system management rights policy, user information, and how to apply them to IOT system smart car and smart home on each object internet.

Recently, the development and dissemination of smart devices linked to the network are being actively performed, and IOT(Internet of things) is issued form of mutually cooperative relationship through interoperation within smart devices. In this paper, we propose an innovative intelligent coffee shop management system by sharing and cooperatively controlling smart devices and Internet devices. The system can order smartphones including kiosk orders and beacon-based user identification. And it is a system that can make custom order without grasping user location information using geofence. The paper provides weather, temperature, time and user-based recommendation services based on Big Data. Therefore, the system is increased cost reduction and work efficiency than general coffee shops.

As the IOT technology has developed, it becomes more big issues about IOT device security. An account management is a nerve-in-the-box routine job for the system administrator and users who manage the several hundreds IOT devices(IP camera, Home IOT, the various measuring equipment). This study is to propose the account management system by the hierarchical design and it is efficient for the user to manipulate the account management. The designed system supports 6 functions for the account management and apply the advanced technologies for the existed system. After the performance of the designed system is validated successfully by the authoritative test, the designed system is applied for the relative fields. And it is on going for the development of the smart account management system by applying the AI technique.

Internet of Things (IOT) technology is rapidly becoming a reality in many parts of our lives through various products and services. Currently, the perception of Internet services for things is becoming common, and the B2C (Business to Consumer) market is explosively increasing as consumers are increasingly willing to purchase Internet devices. In particular, the economic effects of the Internet based smart home sector are known to be very large, and global manufacturers are launching various consumer oriented products based on smart home services.However, current smart home service products are closed systems because they provide independent devices for each manufacturer and provide only specific devices and services linked to them. There is a need for an environment that can provide intelligent smart home service through linkage between objects or services, and a controller that can provide smart control is needed. Therefore, this paper proposes a smart home remote control that can control the Internet devices and services of objects. The proposed smart home remote control provides an environment in which users can directly rescue services through the IFTTT automated service platform, which is an independent platform for each manufacturer.

본 논문에서는 Arduino MEGA 2560을 이용하여 JSN270을 통한 와이파이 시스템으로 집안에 있는 모든 전자제품을 제어 할 수 있는 컨트롤 제어 시스템이다. 스마트폰 어플리케이션을 집 내부의 각종 전자기기, 센서, CCTV와 연동하여 사용자가 간편하게 구동 할 수 있고 또한 인체 감지 센서를 통해 상시 감시하여 움직임을 감지시 경보 시스템을 작동 시키도록 설계되어져 있다. Arduino MEGA 2560을 이용한 프로그래밍을 기반으로 와이파이를 통해 내부를 포함한 외부에서도 각종 전자 부품을 ON/OFF 시킬 수 있으며 Raspberry Pi를 통해 카메라로 집 내부, 외부를 확인하여 어플을 통해 도어락을 해제 시킬 수도 있다.

우리에겐 익숙하고 쉽게 느껴지지만, 누군가에겐 어려운 것들이 존재한다. 예로 시각 장애인에게는 거리를 돌아다니는 것, 거리를 달린다는 것은 상당한 용기가 필요한 일이다. 경북대학교 재학 중인 시각 장애인 김경훈 학우는 자신의 유튜브 채널에 등교하는 거리에 익숙해지도록 여러 번 걸어 다니며 연습하는 모습의 영상을 올린 적이 있다. 또 다른 시각장애인은 국민 청원에 트레이닝에 대한 지원 요청을 한 적이 있다. 우리는 이런 사례들을 조사하여 거리에 나가지 않아도, 위험요소를 생각하지 않아도 할 수 있는, 그 누구도 차별 받지 않고 모두가 자연스럽게 운동에 집중할 수 있는 홈 트레이닝 시스템을 구현하였다.

With the development of IOT technology and the expansion of ICT services recently, a variety of home network services have been advanced based on wired and wireless high speed telecommunication. Domestic and global companies have been studying on the innovative technology for the users using IOT based technology and the environment for the smart home services has been gradually developed. The users live their lives with more convenience due to the expansions and developments of smart phones. However, the threatening on the security of the smart home network had occurred by various attacks with the connection to the smart environment telecommunication, lack of applications on low powered and light weight telecommunication, and the problems of security guideline. In addition, the solutions are required for the new and variant attacking cases such as data forgery and alteration of the device for disguising approach with ill will. In this article, the safe communication protocol was designed using certification management technique based on AKI which supplemented the weakness of PKI, the existing certification system in the smart environment. Utilizing the signature technique based on ECDSA, the efficiency on the communication performance was improved, and the security and the safety were analyzed on the security threat under the smart home environment.
