Recently software security of the smart phone is an important issue in the field of information science and technology due to fast propagation of smart technology in our life. The smart phone as the security critical systems which are utilizing in terminal systems of the banking, ubiquitous home management, airline passengers screening, and so on are related to the risk of costs, risk of loss, risk of availability, and risk by usage. For the security issues, software hazard analysis of smart phone is the key approaching method by use of observed failures. In this paper, we propose an efficient integrative framework for software security analysis of the smart phone using Fault Tree Analysis (FTA) and Failure Mode Effect Analysis (FMEA) to gain a convergence security and reliability analysis technique on hand handle devices. And we discuss about that if a failure mode effect analysis performs simpler, not only for improving security but also reducing failure effects on this smart device, the proposed integrative framework is a key solution.

In these days, the trends of home networking system is implementation of easily configured system with home security of emergency alarm and visitor verification services. In this paper, we implemented push server system based on Arduino of open source physical computation platform to verify visitors for the homes without home networking services. In the suggested system, visitor verification is performed in and out of home, and home access security of the system could be constructed with low-cost price by use of windows push server system and smart devices with alarm operation in corresponding to not allowed access trying.

This study introduces server-side security-oriented framework for smart financial service. Most of domestic financial institutions providing e-banking services have employed server-side framework which implement service-oriented architecture. Because such architecture accommodates business and security requirements at the same time, institutions are struggling to cope with the security incidents efficiently. The thesis suggests that separating security areas from business areas in the frameworks makes users to be able to apply security policies in real time without considering how these policies may affect business transactions. Security-oriented frameworks support rapid and effective countermeasures against security threats. Furthermore, plans to avoid significant changes on existing system when institutions implement these frameworks are discussed in the report.

Home network system makes it available for controlling inside home and for controlling from outside as well with personal computer, cellular phone or smart phone, by connecting diverse information equipments within home such as lighting, gas, and heating equipments with network Integrated server and wall-pad, which form home network system, have demerits as saying of being high-priced and of needing to implement network infrastructure. Also, there is also risk, which is unavailable for controlling equipments inside home, or can cause malfunction of equipments given the occurrence of a problem about integrated server This study suggested the intelligent home network system, which uses smart phone of supplementing these merits of home network system. It substituted high-specification input & output equipment in the currently and widely supplied smart phone for display and touch screen, which are user interface part of the existing wall-pad, and suggest the common home network system by concentrating management and control function of home network on smart phone.

A sensor network is composed of a large number of sensor nodes which have sensing, computation and wireless communication capabilities. The sensor node sends such collected data, usually via radio transmitter, to a command center (sink) either directly or through a data concentration center (a gateway). These sensor networks can be used for various application areas such as health, military, home network, managing inventory, monitoring disaster areas and so on. Moreover, owing to the rapid growth of mobile technology, high-performance smartphones are widespread and in increasing cases are utilized as a terminal device. In this paper, we propose a home management system using smartphone and sensor networks.

아이폰 출시 이후로 스마트폰의 강세를 이루는 현재, 스마트폰의 보안문제도 많은 화제가 되고 있다. 그 중에서도 Active X를 설치해야 사용할 수 있는 공인인증서가 스마트폰 환경에서 사용할 수 없는 문제가 제기 되었다. 그 대안으로 KISA나 ETRI에서 스마트폰에서 공인인증서를 사용할 수 있는 앱(Application)을 개발 중이지만 공인인증서를 사용하지 않고 USIM정보와 해시함수를 이용하여 기존의 PKI시스템보다 시스템 복잡도를 낮추며 공개키 프레임워크의 확립 및 관리와 관련된 비용절감 효과를 볼 수 있는 시스템을 제안한다.

스마트폰의 대중화와 고성능화로 인하여 다양한 센서들이 부착되고 이를 활용한 서비스가 활발히 출시되고 있다. 이들 중 GPS 위치정보를 기반으로 한 상황 인식 서비스는 다양한 분야에서 킬러 서비스로 각광을 받고 있으나, GPS 위치획득방식 특성상 실내에서는 서비스가 제한되는 문제를 안고 있다. 최근에는 GPS를 대신하여 사용자의 실내위치를 파악하기 위해 NFC, iBeacon과 같이 스마트폰 운영체제에서 제공하는 근거리통신기술을 활용하는 사례가 점차 증가하고 있다. 본 논문에서는 근거리통신기술 중 iBeacon을 사용하여 대학교에서 유용하게 활용할 수 있는 스마트 출석관리 시스템을 제안하고자 한다. 제안된 시스템은 iBeacon과 학생의 스마트폰 간에 BLE(Blutooth Low Energy) 통신을 통하여 출석 정보를 자동으로 수집한다. 또한, 출석정보의 효율적인 수집과 실시간 확인을 위하여 발간/구독 기반의 DDS 미들웨어를 프레임워크로 사용한다.

최근 무선 통신 기술의 발전으로 무선 매체를 통한 다양한 서비스가 활발해지고 있다. 그 중 블루투스를 기반으로 하는 스마트 폰 어플리케이션 시장이 증가하고 있다. 블루투스는 근거리 무선 네트워킹 기술로서 무선이라는 요소와 빠른 전송속도라는 요소를 갖추고 있다는 장점이 있는 반면, 높은 전력소모와 다채널의 갯수 제한 등과 같은 단점이 존재한다. 이러한 블루투스의 단점을 보완하여 부상되고 있는 것이 지그비(Zigbee) 무선통신기술이다. 지그비는 블루투스나 와이파이 등의 기술보다도 저전력, 저가격, 다채널, 브로드캐스팅, 사용의 용이성을 지원하고 있다. 본 논문에서는 센서와 스마트 폰 사이의 무선통신기술로서 지그비를 이용하여서 근거리 무선 네트워크 시스템을 설계하여서 블루투스에 비해 낮은 전력소모와 다채널의 지원을 이용하여 다수의 다양한 센서를 스마트 폰과 근거리에서 실시간으로 무선 네트워크를 제어할 수 있는 시스템을 설계하였다.

In recent years, smart technology has been applied to various information system fields. Especially, traditional library service area is changing to Smart-Library from Digital-Library. In this environment are need to library service software platform for supporting variety content, library services, users and smart-devices. Due to this, existing library service has a limitation that inhibits semantic interoperability between different heterogeneous library systems. In this paper, we propose Linked-Open-Data based smart library as an archetype of future-library system that provide a variety content and system interaction and integration of services. It is an innovative system of the cutting-edge information intensive. Therefore, we designed system environments according to various integration requirements for smart library based on Linked-Open-Data. And, we describe the functional requirements of smart-library systems by considering the users' demands and the eco-systems of information technology. In addition, we show the reference framework, which can accommodate the functional requirements and provide smart knowledge service to user through a variety of smart-devices.
