Abstract

This paper proposes a relational security model-based RDF Web ontology access control model. The Semantic Web is recognized as a next generation Web and RDF is a Web ontology description language to realize the Semantic Web. Much effort has been on the RDF and most research has been focused on the editor, storage, and inference engine. However, little attention has been given to the security issue, which is one of the most important requirements for information systems. Even though several researches on the RDF ontology security have been proposed, they have overhead to load all relevant data to memory and neglect the situation that most ontology storages are being developed based on relational database. This paper proposes a novel RDF Web ontology security model based on relational database to resolve the issues. The proposed security model provides high practicality and usability, and also we can easily make it stable owing to the stability of the relational database security model.

이 논문에서는 관계형 보안 모델 기반의 RDF 웹 온톨로지 접근 제어 모델을 제안한다. 시맨틱 웹은 차세대 웹으로 인식되고 있으며 RDF는 시맨틱 웹을 실현하기 위한 웹 온톨로지 서술 언어이다. RDF와 관련된 많은 연구들이 진행되었으나 대부분 에디터, 저장소 및 추론 엔진 등의 연구에만 집중되었을 뿐 정보 시스템의 가장 중요한 요구 사항 중 하나인 보안 문제에 대한 연구는 매우 미비하다. RDF 온톨로지 보안에 대한 일부 연구들이 제안되었으나 관련 데이타를 모두 메모리에 로딩해야 하는 오버헤드를 지니며, 현재 대부분의 온톨로지 저장소가 관계형 데이타베이스를 기반으로 개발되고 있는 상황을 고려하지 않고 있다. 이 논문에서는 이러한 문제점을 해결하기 위한 관계형 모델 기반의 새로운 RDF 웹 온톨로지 보안 모델을 제안한다. 제안된 보안 모델은 높은 실용성과 활용성을 제공하며, 또한 관계형 보안 모델의 안정성에 기인한 제안 모델의 안정성 확보가 용이하다.
