The importance of personal data protection is increasingly emphasized both at home and abroad, and while overseas countries are applying various policies and dynamic management technologies, there are some gaps between compliance with laws and regulations and the application of technologies in Korea, and there are few user interfaces that provide convenient ways for data subjects to stop processing personal data. This study first analyzes the need for dynamic personal information consent management technology, the current state of the industry, and the prospects for its development. Next, this study proposes a basic model for dynamic management of personal information consent that maximizes the data subject's right to personal data self-determination while strictly complying with personal data protection laws in Republic of Korea. In particular, this study analyzes the basis of domestic laws and regulations related to the suspension of personal data processing, designs a basic model of personal data consent dynamic management interface, and presents its effectiveness. Based on the results of this study, we expect that the proposed dynamic management model for personal data use consent can be used in various ways for various websites and applications in the future.

There is a need for content providers and operators to control the usage of downloaded digital contents. Digital Rights Management(DRM) is the means to control the usage of the digital contents once it has been downloaded. Therefore, appropriate security mechanism is required. The mobile DRM system Is same as the general DRM system. We use encryption technology to package digital contents. In case of Mobile DRM system, secure distribution and secure keeping of packaging encryption key is important. In this paper, we design and implement DRM system on the Mobile Environments following on OMA(Open Mobile Alliance) DRM Model. We considered being a secure DRM system to contain appropriate security solution.

Existing tools using in the standard e-learning contents authoring were used a method to provide users contents template produced in advance. In order to use resources of the template in a common web-based authoring tool, there is problem to overcome. If the resource of template is inserted within the contents on the authoring tool, the deformation of the template by the user's input that may occur during the edit process cannot be controlled. In this paper, we propose an effective maintenance method to prevent deformation of the resource of template inserted into any WYSIWYG-based HTML authoring tool by user's discretion. We added a template plug-in that can create the IMS-QTI standard resource in tynyMCE the web-based open source editor of representative examples. And the plug-in for tinyMCE was realized as a module of directly respond to the action of limited user input. So, in response to the action of user's input, the structure of the template can be sustained possibly.

최근 데이터가 전략적 의사결정의 핵심요소로 대두됨에 따라 데이터 통합 및 데이터 품질에 대한 관심이 증대되고 있다. 특히, 데이터 품질을 확보하기 위해 데이터 표준화가 필수적으로 수반되어야 한다. 그러나 데이터 활용에 있어 (1)데이터의 중복 및 불일치 발생, (2)데이터에 대한 의미 파악 지연으로 정보 제공의 적시성 결여, (3)데이터 통합의 어려움, (4)정보시스템 변경 및 유지 보수 곤란 등과 같은 현실적인 문제점들이 정확한 정보를 적시에 사용자에게 전달하는데 장애 요인으로 발생하고 있는 실정이다. 따라서 본 연구에서는 '국토관측센서 기반 수문 및 수재해 정보포털시스템 개발'에 앞서 보다 정확한 데이터 통합관리 및 제공서비스가 가능하도록 국내외 사례연구를 통한 기반을 마련하고자 한다. 데이터 표준화는 시스템별로 산재해 있는 데이터 정보요소에 대한 명칭, 정의, 형식, 규칙에 대한 원칙을 수립하여 이를 전사적으로 적용하는 것을 의미하며, 이러한 데이터 표준화 작업은 데이터의 정확한 의미 파악뿐만 아니라 데이터에 대한 상반된 시각을 조정하는 역할을 수행한다. 기본적으로 데이터 모델 및 데이터베이스에서 정의할 수 있는 모든 오브젝트를 대상으로 하는 것이 이상적이나, 주로 관리해야 될 필요성이 있는 오브젝트만을 대상으로 데이터 표준화를 하는 것이 더욱 효율적으로 작용한다. 본 연구는 국내외 데이터 통합관리 표준화 동향을 제시하였으며, 현업 사용자로부터 데이터 표준과 관련된 요구사항을 수요조사를 통하여 조사함으로써 데이터 표준 대상 후보를 식별하고 개선점을 도출하는데 사용할 기반을 마련하였다. 데이터 표준화가 수행되면 현업 사용자는 정확한 데이터를 사용할 수 있고, 올바른 의사결정을 내릴 수 있을 것으로 판단된다. 앞으로 데이터 표준, 데이터 표준 준수 체크, 데이터 표준 조회 및 활용 등 데이터 표준 관리에서 수작업으로 인해 발생하는 애로사항을 배제하기 위해 자동화에 관한 연구가 지속적으로 추진되어야 할 것으로 사료된다.

In various fields, ISO/IEC 11179-based MDR (Metadata Registry) systems have been developed. However, the current systems do not observe the standard, so inconsistency issue between metadata arises. Most of all, there exist several problems because ISO/IEC 11179 provides no standardized access method. SQL/MDR has been suggested to resolve those problems. SQL/MDR supports search operations, but it does not provide operations for vaild building and safe access for MDR. This paper, in the aforementioned issues, suggests MCL(Metadata Control Language) to guarantee safe and easy access control. MCL offers predefined roles and authority of user groups defined in ISO/IEC 11179 Part 6, and users are assigned to a proper user group. With such a way, MCL increases usability and security.

In this paper, we propose the TPS (TPM-enhanced Privacy Protection System) which is an automated privacy protection system enhanced with a TPM (Trusted Platform Module). The TPS detects documents including personal information by periodic scanning the disk of clients at regular intervals and encrypts them. Hence, system manages the encrypted documents in the server. In particular, the security of TPS was greatly enhanced by limiting the access of documents including the personal information with regard to the client in an abnormal state through the TPM-based platform verification mechanism of the client system. In addition, we proposed and implemented a VTF (Virtual Trusted File) interface to provide users with the almost identical user interface as general document access even though documents containing personal information are encrypted and stored on the remote server. Consequently, the TPS automates the compliance of the personal information protection acts without additional users' interventions.

The purpose of this study is to propose strategies for enhancing competitiveness through the utilization of policy funds, especially in the start-up companies supported by the Korea Credit Guarantee Fund. And then, the Korea Credit Guarantee Fund should develop 'user-centered policy funding model' in order to increase start-up's utilization of policy fund and support start-ups that are supported in the long run. The competitiveness of domestic start-up companies has been strengthened by 'user-centered policy funding model' and new innovations have been introduced through 'Living Lab', an open innovation. But, in order to overcome the limitation of reaching the stage of commercialization, the 'user-centered policy funding model' proposed in this study enables start-ups to be the subject of actual policy funding, and also allows users to freely apply for necessary funding at any time. Therefore, the Korea Credit Guarantee Fund has a significance in suggesting 'user-centered policy funding model' as a support model to be customized. However, since SMEs recognize the actual situation and limit acceptance of all the difficulties, the systematic analysis of the actual situation of the policy funds of the start-up by the credit guarantee fund and the related support institutions for the scientific approach of the user-oriented policy funding model need.

Due to the development of IT technology and the spread of infectious diseases, online non-face-to-face services are rapidly expanding. In particular, the information delivery process is also changing from the past postal branch-based to an information delivery system using mobile devices. This change is due to the change from the information delivery using the telephone line to the information delivery system using the Internet. Mobile notification service is a service that sends electronic notices to mobile devices held by users to deliver information and is validated for delivery, which has the advantage of reducing the benefits of unnecessary mail production, exposure to personal information, and misdelivery. However, user identification information must be provided to operators that provide mobile electronic notification services. In this paper, the current state of use of the mobile electronic notice service, which has been in effect since 2019, is investigated and analyzed, and the current mobile electronic notice service is to be safely provided and to take appropriate protection measures for personal information. In providing the mobile electronic notification service to users, it is possible to identify the service standards required by the sending agency, and based on this, prepare the technical standards for the mobile electronic notification service that the sending agency must comply with in advance and use it for the mobile electronic notification service.

Recently, cloud data management has been actively studied along with the development of a cloud computing technology that can process large amounts of data at a lower cost. However, the existing cloud computing platforms do not guarantee interoperability according to the construction environments of users because they do not provide technical and political openness. In other words, in order for users to receive the related services, they use services provided by only one vendor. In this paper, we design and implement a storage interface that supports the international standard CDMI in order to retrieve, update, and delete data in could environments. These interfaces provide the functionality required for developers who want to build and use the cloud storage without special restrictions. In addition, we verify the operability and usability of CDMI international standard through the implementation of the proposed system.
