This research examines how IoT makes a significant contribution to the innovation of media firms. The media firms will be able to find new reveue sources and strengthen firms' competence through innovating product, process and business model. While IoT increases the experience of interactivity and immersion for consumption, it improves the way ads are exposed and its impact is measured, leading to revenue increase. For these benefits fulfilled, innovation friendly media eco-system must be established. It is the most critical that media firms should change skeptical attitude toward IoT's potential and actively invest it to employ IoT. The government should create regulatory framework to best utilize the innovative advantages of IoT.

Recently, the Internet of Things are developing in accordance with the technology of implementation in low-cost, small-size, low power consumption and smart sensor that can communicate using the internet. Especially, key management researches for secure information transmission based on the Internet of Things (IoT) are actively performing. But, Internet of Things(IoT) are uses sensor. Therefore low-power consumption and small-memory are restrictive condition. As a result, managing the key is difficult as a general security measure. However, The problem of secure key management is an essential challenge For the continuous development of the Internet of things. In this paper, we propose a key distribution and management technique in secure Internet of things. In the key generation and management stage, it satisfies the conditions and without physically constrained for IoT based communication.

As the scale of the Internet of Things (IoT) environment grows and develops day by day, the information collected and shared through IoT devices becomes increasingly diverse and more common. However, because IoT devices have limitations on computing power and a low power capacity due to their miniaturized size, it is difficult to apply security technologies like encryption and authentication that have been directly applied in the previous Internet environment, making the IoT vulnerable to security threats. Because of this weakness, important information that needs to be delivered safely and accurately is exposed to the threat of malicious exploitation, such as data forgery, data leakage, and infringement of personal information. In order to overcome this threat, various security studies are being actively conducted to compensate for the weaknesses in IoT environment devices. In particular, since various devices interact, and share and communicate information collected in the IoT environment, each device should be able to communicate with reliability. With regard to this, various studies have been carried out on techniques for device authentication. This study examines the limitations and problems of the authentication techniques that have been studied thus far, and proposes technologies that can certify IoT devices for safe communication between reliable devices in the Internet environment.

Internet of Things(IoT) using a variety of technologies in combination provides a convenient, elevated range of services to users. IoT has been noted in combining the fields of medical service in particular. However, with the advent and growing of IoT, the more medical services are evolving, security problems caused by leakage of personal health information will become more serious. U-Health and medical devices, which deal mainly the personal health information, is required to a high level of privacy and security of health information. Therefore, the introduction of the IoT in the healthcare industry requires the medical information security as a prerequisite. This study analyzes security status and trend of IoT, personal medical information leakage cases, the health information protection measures in accordance with the life cycle of medical information, and the standardized protection technologies.

In recent years, the maker culture has realized the concept of 'making' itself through the latest technology of high technology. It is rapidly spreading as a maker's movement by sharing the production methods and information of individuals through the Internet. Countries that are leading the makers' movement expect the maker's movement to be the driving force for new value creation and economic growth from the point of view of things and the Internet. We are developing various types of open IoT platforms that can register various Internet devices and services manufactured and developed through DIY and realize interoperable services. Typical open IoT platforms require specialized API analysis capabilities and difficult access to general users due to difficult platform registration conditions and procedures. In this paper, we try to construct an open IoT platform that can be operated as a real service by creating a simple Internet application device and service application from a general manufacturer's point of view.
