Recently, Construction business is changing from on the ground to underground space because of deficit of developing space, creation of green space and of incremental of land compensation expenses. Meanwhile, 3D Topographic, Marine and Cadastral maps need to have Spatial Interrelation. Also, understanding of the information is also needed. Spatial information object registration system is impossible to contact and understanding intelligence mutually because the former one is managed as automatic ID system. Therefore, 3D Object information ID System of underground space is managed based on Object Identifier. Construction of Spatial information integration ID System is required and it will offer Division Code (Ground, Index, Underground) and depth information. We are defined and classified Under Spatial Information in this paper. Moreover, we developed the integration ID System based on UFID for cadastral information Construction. We supposed underground spatial information DB Construction and a developed the way of exploiting 3D cadastral information system through the study. The research result will be the base data of Standard ID system, DB Construction and system Development of National spatial data which is considered together with spatial interrelation.

The study concluded that in order to achieve a single sign-on through the federation ID management method must be used among many other methods so to establish a combined approval service that gives access to education related information provided by the 16 city and provincial offices of education and the KERIS(Korea Education & Research Information Service). The federation ID management method allows the usage of authentication policy and enables transfer of ID information to other institutions through standardized processing. Therefore by establishing single sign-on through the federation ID management method allows individual city and provincial office of education to maintain the already existing approval services while combining user identification database.

인터넷 서비스를 사용하기 위해서 사용자들은 이름과 주민등록번호로 실명 인증을 받은 후에 ID를 부여 받았으나, 최근 보안상 문제로 주민등록번호 대체 수단인 I-PIN 서비스를 사용하고 있다. 그리고 하나의 ID로 통합하여 인터넷 서비스를 받을 수 있는 OpenID 서비스가 국내에서도 시행중이지만 사용자 인증이 없어 악성 댓글과 스팸 등으로 악용될 수 있으며 피싱에 대한 문제점을 지적하고 있다. 본 논문에서는 OpenID에서 회원가입을 할 때 I-PIN을 사용하여 사용자 인증을 하는 기법을 제안하고 악의적인 IDP와 RP의 피싱 문제점을 보안하였다. 기존의 OpenID와 I-PIN을 적용한 OpenID를 비교분석을 통하여 보안적인 측면이 강화된 것을 확인할 수 있으며 피싱에 안전하도록 설계하였다.

Grid services offer SSO(single sign-on) mechanism using GSI(grid security infrastructure) based on X.509. However. portal applications in web environment use ID and password model for single sign-on. Grid portals means a system which provides grid services by integrating portlet contents on single web interface. In existing research such as GAMA and PURSE, SSO for a whole grid portal is figured out in the way that user is authenticated by ID and password in front and call grid service via GSI at back-end. Other types of web applications outside of portlet framework cannot unfortunately access grid service in SSO way in the existing researches, because the SSO mechanism is developed for portlet framework only. In this paper, we suggest a SSO mechanism based on ID and password model, which forwards authentication information and a GSI token for grid access among portlets and grid-enabled web applications. This mechanism is applied to MGrid for SSO, which consists of applications of java web start, applet, servlet, and etc. as also as portlets.

In order to use an Internet service, it is a general procedure that user subscribes to the service and then registers her or his id(identifier). As Internet has been more widely used, however, user has more and more ids than ever before. In this environments, whenever user uses an Internet service, she or he must authenticate to the service provider, which makes her or him inconvenient. As user's data is scattered and unmanaged on various web sites, user privacy has been revealed more often. This paper specifies e-IDMS which ETRI has been developing to solve such problems. e-IDMS is an Internet ID(IDentity) management system based on ID Federation Mechanism e-IDMS provides ID Federation-based facilities such as composite authentication, Internet SSG, ID information management, privacy protection and interactive query. e-IDMS is used in establishing integrated ill management system for public institutions.

The vulnerability of privacy in the Identity Management System (IMS) is the most pressing concern of ordinary users. Uncertainty about privacy keeps many users away from utilization of IMS. Therefore, this paper proposes an access-control oriented privacy model for IMS. The proposed model protects privacy using access control techniques with privacy policies in a single circle of trust. We address characteristics of the components of for the proposed model and describe access control procedures. After that, we show the architecture of privacy enforcement and XML-based schema for privacy policies.

현재의 IPTV 시비스는 VoD+PPV와 같이 단순한 형태로 서비스를 제공하고 있다. IPTV 서비스 사업자들은 IPTV의 새로운 수익모델인 양방항성 통신특성에 최적화된 서비스를 제공해야 한다. 양방향 통신의 대표적인 서비스로는 T-commerce가 있다. T-commerce 서비스 제공시 IPTV 가입자의 정보가 제3의 서비스 사업자로 전송되기 때문에 개방된 IP망에서 가입자의 정보가 전송되므로 개인정보보호의 중요성이 커지게 될 것이다. 양방향 서비스를 제공하면서 개인정보보호를 유지하는 방안으로 ID를 통합적으로 관리하는 기술인 IdM(Identity Management)을 IPTV에 적용하는 방안이 고려되고 있다. 본 논문에서는 NGN(Next Generation Network)기반 IPTV의 IdM 적용방안에 대해 기술한다.

In 4G environments, which is the next generation technology for mobile network, it is forecasted that the wireless Internet using a mobile devices such as a mobile phone, PDA will increase because of expansion of Internet and integration of heterogeneous networks. Therefore, we need a Digital ID management technology that can prevent illegal uses and manage private information efficiently in wired and wireless environments. In this paper, we analyze various Digital ID management technologies, and then define requirements of user-centric Digital ID management technology. In addition, we newly propose the authentication mechanism for mobile applications in LTE/SAE network. Finally, we propose the mobile Digital ID Wallet mechanism suitable for 4G environments.
