Much research has been recently accomplished for standardization in cloud computing. However, little research on standardization of data sharing and exchanging has been studied. Most of all, the corresponding standardization organization suggests no specific standardization items and reference model. This paper defines the current standardization problems and proposes a set of specific standardization items and a reference model for supporting the semantic interoperability. To achieve the goal of this paper, the overall standardization trend in cloud computing is first analyzed. Especially, this paper describes the status of standard development for addressing the semantic interoperability of data. This paper also defines the potential standardization items based on the concepts of standards in the data exchanging and management field, which are used for developing standards in various fields. Finally, the reference model is describe to show the relationships between items and overall semantic interoperability process. This paper can be used as a guideline for development of standards and also can facilitate standardization of cloud computing.

The current cloud system is not compatible as low interoperability between cloud systems because they build up cloud environments with their own way. For example, users who are using Google's cloud system, it will not be able to use the cloud system of MS (Microsoft). To solve these problems, CSB (Cloud Service Broker) technology appeared, but solves interoperability problems between cloud systems require circumstances to develop and still much research. In this study, in the CSB, which has appeared as a service intermediary technology of heterogeneous distributed cloud environment (Cloud Service Broker) technology, to study authentication system, which is a fundamental problem to be solved of the interoperability of the cloud user.

The development of cloud computing technology and smart devices have increasingly been expanding the influence in various fields. Although DRM(Digital Rights Management) is a very important technology for secure content services, interoperability among DRM technologies must be addressed in order to provide the service without the constraints of time and place on various smart devices. In this paper, we study DRM Cloud which provides DRM functions as a service in cloud computing environment, and address interoperability problem by providing different DRM technologies as a cloud service. That is, when a user wants to play contents with the different DRM technologies on a smart device, the usage of the content is controlled by providing the corresponding DRM module and function as SaaS from DRM cloud. To do this, we define the functions and structure of DRM Proxy which performs smooth service call and provision between DRM cloud user and DRM cloud, and finally we describe the experimental implementation result.

After making amendments to archive-related legislations in 2006, the Electronic Records Management Systems (ERMS) were introduced into public institutions. With this, most institutions constructed digital repositories in their records center. In this system, there are several weaknesses that wasted costs and manpower for its introduction and maintenance. The extensibility of a repository is debased, and securing the interoperability is difficult. The study proposed a cloud computing-based model to solve such problems that the previous system had. In particular, this study expected effects through the proposed model. The expected effects are low-cost, highly efficient, extensible, and interoperable in embracing various systems. Thus, the appropriateness of introducing cloud computing into ERMS was analyzed in this study.

Currently, cloud systems are not interoperable due to low interoperability between cloud systems as operators build up cloud environments with their own way. For example, users of the Google cloud system can not use the Microsoft (Microsoft) cloud system unless they go through an additional log-in process. In order for Google cloud system's users to use MS cloud system services, they must log in to the MS cloud system again after logging out of Google cloud system. In order to solve these problems, Cloud Service Broker(CSB) technology has emerged to resolve the interoperability problem between cloud systems, but many researches and developments are still needed. In this paper, we design an integrated user authentication system, which is a fundamental problem of cloud user interoperability among CSB (Cloud Service Broker) technologies, which is emerging as a service intervention technology of heterogeneous distributed cloud environment.

클라우드 컴퓨팅 서비스의 많은 장점에도 불구하고 아직 기업들이 서비스의 가용성 및 데이터 보안, 자사 데이터에 대한 통제권 확보, 종속성 등의 문제로 클라우드 컴퓨팅 서비스의 이용을 꺼리고 있다. 이 같은 문제들은 기술개발, 표준화, 표준약관, 서비스수준협약(SLA) 등으로 어느 정도 해결이 가능하다 그러나 데이터가 여러 국가에 복제되어 분산 저장될 경우 데이터의 국외이전 금지 문제, 데이터의 보관 및 파기 의무, IT 컴플라이언스 수탁자의 불법행위에 대한 위탁자의 책임, 자신의 데이터센터에 저장된 불법정보에 대한 클라우드 서비스제공자의 책임범위, 클라우드 서비스제공자의 책임제한 등 현행법상의 법적 규제와 충돌되는 부분에 대해서는 법. 제도적 접근과 검토가 필요하다. 클라우드 컴퓨팅 산업의 촉진 및 이용 활성화를 위해서는 구체적으로 다음과 같은 사항이 법 제도적으로 검토되어야 한다. (1) 클라우드 서비스나 솔루션을 시험할 수 있는 테스트베드 구축 등 시범사업 근거 마련, (2) 분야별 특화된 클라우드 서비스 모델 개발 및 사업화를 위한정부시책 추진 및 지원 근거 마련, (3) 민 관의 포괄적 협력 기반조성 및 정부의 기술 개발연구 지원체계 마련, (4) 사전 인증 및 사후 보증체계 구축을 통한 클라우드 서비스의 신뢰성 및 안정성 제고, (5) 클라우드 서비스의 상호운용성 확보를 위한 표준화, (6) 클라우드 컴퓨팅의 정보보안, 개인정보보호 등 각종 법률 이슈와 예상되는 다양한 이해관계 충돌 문제에 대응할 수 있도록 서비스제공자와 이용자 대상의 지침 근거 마련, (7) 클라우드 속에 있는 기업의 정보지산에 대한 접근권 보장, (8) 정보자산의 실제 위치와 선택권 보장, (9) 정보자산의 부적절한 접근 방지와 오남용 방지, (10) 클라우드 서비스 제공기업 또는 서비스 자체의 영속성 보장, (11) 서비스 장애 책임범위와 분담, (12) 소프트웨어 라이선스 등에 대한 규정이 고려되어야 한다.

The mobile devices and cloud computing technology introduced new content services such as N-Screen service. The DRM techniques have been developed to support interoperability and multi-platform for new environment of content service. Nevertheless, it is still inconvenient for the consumers to purchase a new DRM-supported device or to migrate some purchased contents into new device due to the change of the subscription of service. Therefore, in this paper, cloud-based DRM model which is referred as DRMaaS (DRM-as-a-Service) model, is proposed to allow the consumer to freely use and move some DRM-protected contents in various smart devices regardless of subscription of service.

In cloud environment, enterprises use a number of systems which are not interconnected and save master information in a distributed way in each of them. Master information which is not managed is incorrect and discord each other so that lowers efficiency of business process and disables optimum decision making. It is necessary to do high-qualified management of master information to operate efficient and errorless business process. This paper suggests TMDM as a solution to solve heterogeneous problems occurred between interconnected master information in cloud environment and to manage business process in an efficient method. TMDM is an information storage that is suggested to solve mutual discord problems between master information using Topic Maps that considers correlation between data. Topic Maps can be connected by association between topics in order to access through a topic to all related knowledge information which is described by the topic. This also can be applied to master information between legacy systems within cloud.
