Most fields of society have constructed and utilized various name identifier systems such and International Standard Name Identifier(ISNI), Open Researcher and Contributor ID(ORCID), and Interested Parties Information System(IPI) in order to uniquely identify individual authors and institutions and to associate them to data related to creative works. Although it might be inevitable to apply name identifier systems in the current data environment with rapid association and integration of data across fields, there are many problems to be addressed when utilizing those systems. In order to overcome these problems and construct better information ecological system by associating and linking data from various fields, this research analyzed advanced cases for data integration based on ISNI. Through the analysis, it suggested managemental refinements for efficiently utilizing ISNI in data integration and association.

최근 사물인터넷에 대한 관심이 증가함에 따라 미래인터넷에 대한 연구가 증가하고 있다. 각기 다른 사물인터넷을 연결하기 위하여 다양한 네트워크 인프라가 필요하며, 사용자뿐만 아니라 다양한 네트워크 자원에서 요구하는 서비스나 콘텐츠 등이 증가하고 있다. 이에 따라 이들을 식별하기 위한 통일된 식별 체계가 필요하다. 이를 위하여 미국에서는 NDN에 대한 연구가 진행 중이며, 이외에도 MobilityFirst, XIA와 같은 프로젝트성 연구들이 활발히 이루어지고 있다. 따라서, 본 논문에서는 기존의 연구들을 보완하고 새로운 미래인터넷에 확장 가능한 통합된 Name-Identifier-Locator 프레임워크를 제안한다.

This study was to investigate the concept of ISNI and to find its availability in authority control, realizing importance of ISNI as the bridge identifier including all the information media content industries. ISNI is needed for global and comprehensive name authority control as the bridge identifier for the identification of public identities of parties involved throughout the information media content industries in the creation, production, management and content distribution chains. First of all, it was to inquire ISNI concept, goal, terms and definitions, structure and syntax, allocation of ISNI, administration of the ISNI system, and metadata. Next, it was to suggest the applicability of ISNI in authority control. First, it should be needed to consider in applying ISNI for cooperative authority control. It is possible to interactively use the authority data created in library and other information industries area by constructing KISNI system. Second, it is possible to construct linked data by linking various identifier through ISNI identifier as bridge identifier. Third, it is needed to develop KORMARC for describing ISNI identifier in KORMARC bibliographic and authority record.

The purpose of this study is to lay the foundation for the construction of an identification system by proposing descriptive items that can identify the creators who participated in the production of broadcasting video records. In order to uniquely identify the creators of broadcasting video records, a total of seven descriptive categories, including name, gender, date of birth, name identifier system, nationality, affiliated agencies, and major fields, were organized into three categories: individual, affiliation, and role. These categories were classified and categorized into two stages. Based on the proposed structure, a total of 10 basic facets and 14 sub-facets were constructed to establish a faceted structure for identifying the creators of broadcasting video records.

This study proposed an integrated management system model of researcher identifiers using the ISNI(International Standard Name Identifier) that can prevent duplicate issuance of identifiers and can be used to reorganize the authors' information. We looked at the metadata structure and management system of the ISNI that can be applied in various fields among identifiers. And we have designed the integrated ID system and system model that can manage the identifiers issued by each institute based on the ISNI. This model consists of data structure layer, platform layer, application layer, management and security layer (4 layers) and we have presented some of the key features and issues to consider when managing the integrations.

In this study, we propose a system for setting a Destination on CNS(Car Navigation System) or PNS(Personal Navigation System). The present Navigation does set the destination by only static method like name search, address search and wire telegraph telephone number search. But, the kind of setting a static destination does not reflect the dynamic moving situation. So we suggest setting the destination of navigation using Identifier of moving terminal. And it includes privacy protection on personal position information

UCI(Universal Content Identifier), a digital content identifier is a identification system based on URN(Uniform Resource Name) for the transparent distribution, efficient search and management of digital contents. Digital contents given a UCI number need metadata for serving a exact contents that users need. However, the only metadata provided by UCI are deficient to represent various information of digital contents, and ontologies which could standardize and define explicitly semantic relations between metadata (provided by UCI) are needed for better representation of information and efficient search and management of digital contents. In this paper, we extended concept-relation between metadata with ontology and designed domain ontology enabling semantic-based search by expanding UCI meta data, and showed the more efficient search and management over the metadata by UCI through various queries.

In this paper, we propose a more effective unique identifier allocation method for macro expansion in a single-process multicore parallel computing environment that does not require locks. Our key idea for such an allocation method is to remove sequential dependencies using the remainder operation. We confirmed that our lock-free method is suitable for improving the performance of parallel macro expansion through the following benchmark: we patched an existing library, which is based on a sequential unique identifier allocation, with our proposed method, and compared the performances of the same program but using two different versions of the library, before and after the patch.

A Certification Authority issues X.509 public key certificates to bind a public key to a subject. The subject is specified through one or more subject names in the 'subject' or 'subjectAltName' fields of a certificate. In reality, however, there are individuals that have the same or similar names. This ambiguity can be resolved by including a 'permanent identifier' in all certificates issued to the same subject, which is unique across multiple CAs. But, a person's unique identifier is regarded as a sensitive personal data. Such an identifier cannot simply be included as part of the subject field, since its disclosure may lead to misuse. We present a new method for secure and accurate user authentication through the PEPSI included in the standard certificate extension of a X.509 certificate. The PEPSI can be served not only for user authentication but also for the user anonymity without divulging personal information.

As the compact and easily accessible handheld devices, such as cellular phones and MP3 players equipped with image acquisition functionality, are becoming widely available among common users, various applications of images are rapidly increasing. Image related services and software such as web-based image presentation and image manipulation for personal or commercial purpose enable users to view contents of remote image archive and to manipulate enormous amount of images in local or network based storage as well. It is necessary for users to identify the images efficiently so that the same images are perceived as one physical entity instead of recognizing them as different images as the trends are getting stronger. In order to support this environment, we propose a method that generates image identifiers or indexing for images within a solid and efficient manner. The proposed image identifier utilizes multiple index values. The integration of component index values creates a unique composite value that can be used as a file name, file system identifier, or database index. Our experimental results on generation of constituent index values have shown favorable results.
