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.

As the supply method of products has become diverse and complex, problems such as manipulation of origin and product trace have occurred in the existing supply chain system. In order to deal with these issues, various Blockchain based studies have been actively carried in the SW industry and academy. However, there is a lack of comprehensive survey research on the applied Blockchain techniques, so that it hardly understand the pros and cons of the technologies. In this study, we intensively investigated the diverse studies from the Industrial and academic area based on the several criteria such as the goals, use of key Blockchain technologies, and IoT technologies.

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.

In a smart home environment that integrates IoT technology into a residential environment, the smart home hub provides convenience functions to users by connecting various IoT devices to the network. The smart home hub plays a role as a gateway to and from various data in the process of connecting and using IoT devices. This data can be abused as personal information because it is closely related to the living environment of the user. Such abuse of personal information may cause damage such as exposure of the user's identity. Therefore, this thesis analyzed the threat by using LINDDUN, which is a threat modeling technique for personal information protection which was not used in domestic for Smart Home Hub. We present evaluation criteria for smart home hubs using the Common Criteria, which is an international standard, against threats analyzed and corresponding security requirements.

The Internet of Things (IoT) is the most creative and focused technology to be employed today. It increases the living conditions of both individuals and society. IoT offers the ability to recognize and incorporate physical devices across the globe through a single network by connecting different devices by using various technologies. As part of IoTs, significant questions are posed about access to computer and user privacy-related personal details. This article demonstrates the three-layer architecture composed of the sensor, routing, and implementation layer, respectively, by highlighting the security risks that can occur in various layers of an IoT architecture. The article also involves countermeasures and a convenient comparative analysis by discussing major attacks spanning from detectors to application. Furthermore, it deals with the basic protocols needed for IoT to establish a reliable connection between objects and items.

Various personalized services are provided based on user context these days, and IoT(Internet of Things) devices provides effective ways to collect user context. For example, user's activity such as walking steps, calories, and sleeping hours can be collected using smart activity tracker. Smart scale can sense change of user's weight or body fat percentage. However, these services are independent to each other and not easy to make them collaborate. Many standard bodies are working on the documents for this issue, but due to diversity of IoT use case scenarios, it seems that multiple IoT technologies co-exist for the time being. This paper propose a framework to collaborate heterogeneous IoT services. The proposed framework provides methods to build application for heterogeneous IoT devices and user context management in more intuitive way using HTTP. To improve compatibility and usability, gathered user contexts are based on MPEG-UD. Implementation of framework and service with real-world devices are also presented.

Since 2000s, proper utilization of IoT (Internet of Things) technology is a key factor for a firm to become more competitive, and this stream is not exceptional for the food and agriculture industry. Along with this stream, Korea government organization, for example MAFRA (Ministry of Agriculture, Food and Rural Affairs), elected to adopt IoT technology, such as USN and RFID technologies, in the food and agriculture industry. Based on the IoT technology, MAFARA launched six "IoT based farm" project in 2007. IoT based farm project includes IoT based greenhouse system project, and it shows drastic efficiency in terms of cost reduction. When it comes to the productivity, however, the effect of IoT based greenhouse system is still ambiguous. In this regard, this study conducted systems analysis and design for IoT based tomato greenhouse in order to help farmers' decision making related to the productivity by establishing standardized database structure and designing output form to analyze productivity indices. Proposed systems analysis and design can be utilized as a data analysis tools by farmers. Productivity data from the proposed systems is can be used by researchers to identify the relationship among environment, plant growth and productivity. Policy makers also can refer to the data and output forms to predict the quantity of fruit during certain period and to revise production guideline more precisely.
