  • 본 연구에서는 특허분석을 통해 빅데이터 분야의 R&D 트렌드를 살펴본 후, 향후 우리나라의 기술개발 방향성을 제시하였다. 특허 분석 결과에 따르면, 빅데이터 분야의 R&D 트렌드는 크게 두 가지 특징을 지니고 있는 것으로 나타났다. 첫째는 미국의 독과점 현상으로 미국은 모든 기술분야에서 비교적 고른 출원 활동을 전개하고 있으며, 기술별 평균 점유율이 40% 이상으로 나타나 세계 시장을 독과점하고 있는 것으로 나타났다. 둘째는 R&D 트렌드의 변화로 과거에는 데이터 분석 및 처리 분야의 기술이 주를 이룬 반면, 최근에는 데이터 운영 및 관리 분야의 기술이 대종을 이루고 있다. 하지만 우리나라의 경우 빅데이터 분야의 특허 출원이 주로 저장기술에 집중되어 있으며, 데이터 운영 및 관리기술에 대한 출원은 상대적으로 저조해 관련 기술에 대한 연구가 시급한 것으로 나타났다.

  • Machine to machine (M2M) communications is the hottest issue in the standardization and industry area, it is also defined as machine-type communication (MTC) in release 10 of the 3rd Generation Partnership Project (3GPP). Recently, most research have focused on congestion control, sensing, computing, and controlling technologies and resource management etc., but there are few studies on security aspects. In this paper, we first introduce the threats that exist in M2M system and corresponding solutions according to 3GPP. In addition, we present several new security issues including group access authentication, multiparty authentication and data authentication, and propose corresponding solutions through modifying existing authentication protocols and cryptographic algorithms, such as group authentication and key agreement protocol used to solve group access authentication of M2M, proxy signature for M2M system to tackle authentication issue among multiple entities and aggregate signature used to resolve security of small data transmission in M2M communications.

  • As the interest in achieving an intelligent society grows with the fourth industrial revolution's development, information and communications technologies technologies like artificial intelligence (AI), Internet of Things, virtual reality, information security, and blockchain technology are being actively employed in different fields for achieving an intelligent society. With these modifications, the information security paradigm in industrial and public institutions, like personal sensitive data, is quickly changing, and it is exposed to different cyber threats and breaches. Furthermore, as the number of cyber threats and breaches grows, so does the need for rapid detection and response. This demand can be satisfied by establishing cyber training programs and fostering experts that can improve cyber security abilities. In this study, we explored the domestic and international technology trends in cyber security education and training facilities for developing experts in information security. Additionally, the AI technology application in the cyber training ground, which can be established to respond to and deter cyber threats that are becoming more intelligent, was examined.

  • Satellite image processing software should be able to support interoperability that is to enable consumers, citizens, large and small businesses and governments to make the fullest possible use of the world's spatial data and spatial processing resources. The goal of interoperability is to perform hands-on research, development, testing, fielding, and validation of potential and existing interoperable geoprocessing technologies. In this paper, component based architecture for fast interoperability is designed to maximize interoperability among the OpenGIS components specified in the OpenGIS abstract specifications and implementation specifications and to mix up the OpenGIS components and the fast access mechanism for high performance.

  • Recently, the need for LBS (Location Based Services) is increasing with the rapid growth of the location measurement units, mobile devices, and communication technologies. Especially, wireless carriers are concentrating on LBS since it is regarded as so-called 'killer application' among wireless data services. Although LBS give us convenience and useful information, its use also raises privacy issues. There are quite possibilities that the people's locations are tracked by location measurement units while people do not recognize the existence of the units. To protect a person's location information, lawful and technical aspects should be considered. In this paper, we explain issues, regulations, standards, and platforms related to the protection of the location information. Finally, we suggest the architecture of a platform complying with the regulations and standards. It considers various issues not covered in other studies.

  • In Korea, we witness vivid evidences of changing trend in communication that insist the emergence of new networking architecture. To accommodate the changing trend and to hold current strong position in global IT industry, Korea have launched broadband convergence network (BcN) initiative. BcN vision for Korea is to be the first in the world to realize converged network infrastructure and ubiquitous service environment. In this paper, we have introduced the concept and the vision of BcN with a viewpoint of a new paradigm to prepare future-proof communication environment. And then, we have disclosed BcN research and development (R&D) activities including R&D philosophy, R&D phases, and key technologies required. Also, we have discussed current development issues in three technology branches including service and control technology, unified transport technology, and next-generation access technology.

  • It is becoming increasingly difficult to identify promising technologies due to the influx of new technologies and the high level of complexity involved in many of these technologies. Identifying promising information and communications technology (ICT)-based converging technologies holds the key to finding new sources of economic growth and forward momentum. The goal of this study is to identify cutting-edge ICT-based converging technologies by examining the latest trends in the US patent market. Analyzing the US patent market, the most competitive of such markets in the world, can yield certain clues about which of the ICT-based converging technologies may be the next revolutionary technologies. For a classification of these technologies, this study follows the International Patent Classification system. As for ICT, there are 58 related fields at the subclass level and 831 fields at the main-group level. For emerging and converging technologies, there are 75 at the main-group level. From these technologies, a final selection for cutting-edge ICT-based converging technologies is made using a composite index reflecting the converging coefficient, emerging coefficient, and technology impact index.

  • 유비쿼터스 컴퓨팅에 대한 개념이 마크와이저에 의하여 제창된 이후 최근 1년은 그 어느때보다 유비쿼터스 컴퓨팅이란 용어가 이슈가 되고 있다. 그러나 유비쿼터스 컴퓨팅이란 용어는 다양한 관점과 용도에 따라 다소 상이하게 정의되고 있어 개념적인 혼돈 상태에 빠져 있는 것이 현실이다. 이에 본 고는 유비쿼터스 컴퓨팅에 대한 개념을 정보 시스템 고유의 관점에서 재조명해보고 이에 기초하여 필요로 하는 핵심 요소 기술 영역에 대한 최근 연구 동향을 살펴봄으로써 향후 유비쿼터스 컴퓨팅 기술연구의 방향을 제시해보고자 하였다.
