The purpose of this study is to explore the necessity and method of the development of modern digital image contents using the story of the literary work 'Guunmong'' by Kim Man-joong. Collective intelligence technique is one of the most recommended. Today, most cultural content development is achieved through the application of digital technology through collaboration of various people from the planning stage to the completion stage. Most prototypes of local cultural contents are developed based on the literary works of artists from the region or background of the region on the works. These local cultural resources can be developed into experiential tourism products and used for the development of local cultural industry. This study first examines the availability of collective intelligence method as a way to effectively develop local cultural contents, and proposes application of image-telling technique and using web-toon characters in digital image contents development. In order to prove the practical applicability of the proposed method, we present an example of cultural contents development of 'Guunmong'. Finally, we propose a new business model based on collective intelligence to develop a system of creation and distribution of the cultural contents through the continuous collaboration.

The technique of developing Digital Contents have still not be a standard, and it is cause some problems in the Digital Contents's creating, circulation and consumption, So solve the problem, MPEG suggest MPEG-21 framework. In the standard, The IPMP take charge of the Digital Contents's protection and management, and also it is the same as the rights expression language REL and the dictionary defining the word of REL. But. the study of the IPMP is later than the study of REL and RDD, such as the other study of the MPEG-21 standard. So, there is few system based REL and RDD. In this paper, in order to management and protect contents right. So facing the latest standard, we designed and implementation the Tool Server and the License Server based on REL/RDD.

The emerging ubiquitous environment is improving IT technologies and the popularization of broadband Internet is encouraging creation and sharing of various contents. The contents include the concept of production and circulation of digital information/contents, in forms of characters, codes, voices, sounds, client and videos for being used on the Internet and networks. The contents are widely shared in networks and users can have a wide range of knowledge and gain the freedom of presentation from them. So now users participations are augmented gradually. However, many contents without acquiring agree of copyright are sharing on the Internet, so many problems happen in the manufacturing process of digital contents. To solve this problem, many research projects to limit contents utilization onto legitimate users and to provide secure contents protection and download, are in progress. Therefore, in this paper, we propose a secure D-CAS system (SDCS) which provides security for contents downloading.

With explosive growth in the area of the Internet and IT services, various types of digital contents are generated and circulated, for instance, as converted into digital-typed, secure electronic records or reports, which have high commercial value, e-tickets and so on. However, because those digital contents have commercial value, high-level security should be required for delivery between a consumer and a provider with non face-to-face method in online environment. As a digital contents, an e-ticket is a sort of electronic certificate to assure ticket-holder's proprietary rights of a real ticket. This paper focuses on e-ticket as a typical digital contents which has real commercial value. For secure delivery and use of digital contents in on/off environment, this paper proposes that 1) how to generate e-tickets in a remote e-ticket server, 2) how to authenticate a user and a smart card holding e-tickets for delivery in online environment, 3) how to save an e-ticket transferred through network into a smart card, 4) how to issue and authenticate e-tickets in offline, and 5) how to collect and discard outdated or used e-tickets.

멀티미디어 기기의 발달과 인터넷의 확산 등의 영향으로 디지털 콘텐츠의 제작 및 유통이 일반화되면서 시장 활성화가 되었지만 불법복제로 인한 시장에 악영향도 미치고 있다. 그리하여 DRM이란 정보보호 기술이 일반화되고 그 기능이 중요하게 되었다. 본 논문에서는 기존의 데이터 전체를 암호화하는 방식의 DRM 시스템과는 달리 H.264/AVC의 특성을 이용하여 콘텐츠의 일부만을 암호화하여 서버에 최소한의 영향을 주면서 영상을 전송할 수 있는 효과적인 DRM 시스템을 제안하였다.

Due to changes in information technology and the information environment, portal services, including library service, which systematically provides information needed on the Internet have become popular in our daily lives. In light of that, this study, in order to enhance our understanding on portal services, examines and analyzes Dibrary, the National Digital Lirary, portal services including main portal, regional information, policy information, multicultural information, the information for the handicapped, and the Dibrary blogs. Accordingly, the emphasis has been put on decency, accuracy, usefulness/user-friendliness, and publicity/promotion for the diffusion and activation of Dibrary portal services.

Currently we have many DRM(Digital Rights Management) products but they do not provide interoperability between them. It causes user's inconvenience to use a DRM content and places restrictions to digital content distribution. DRM standardization to solve these sorts of problem has been discussed but dominant standardization which can provide DRM interoperability has not been made. In this paper, we propose DRM interoperable scheme by connection between heterogeneous DRM systems (EU) which uses export and import functions. Proposed EXIM can make a DRM content exchangeable between heterogeneous DRM systems with an open type of technology specification although they don't have to open their DRM structure.

With explosive growth in the area of the Internet and IT services, various types of e-documents are generated and circulated. An e-Document is a sort of electronic records which a organization performs works and goals. In this study, we propose a security algorithm for secure use and distribution of e-documents. Especially, the proposed method can be applied to generate digital signature which can guarantee authenticity, integrity, confidentiality of an e-document and authenticate authorized users. Also, we can get higher security level as using a smart card that provides highly storing capacity and security. We carried out an experiment to verify efficiency and security of the proposed method.

By effect of infinity internet market copyright connection skills for extent extension of digital contents and profit rescue through this impoliticly research and develop. Contents protection techniques, management techniques, circulation techniques etc. are becoming development by contents circulation company and developers but that there is no standard as problem advances soul between copyright managerial system by development competition and in reciprocity compatibility tell. ISO MPEG commission arrived that develop MPEG-21 framework to solve problem that do that is to copyright management's opacity province that non efficiency and standard of contents distribution structure that do that is by redundancy investment are not. Data structure in Framework interior is doing and propose copyright expression language of XML base of REL to establish copyright connection data standard and normalized based on no XML. But, a tool that can be easy as must understand whole framework and can have problem in to edit REL and create copyright document fast was required. In this paper, research about method that edit REL document and develop and spend a edit tool that tan be that expressing intuitionally.

단행본, 소설, 잡지, 만화 등 다양한 형태의 전자출판물에 공통적으로 적용 가능한 표현 기술과 콘텐츠 유통을 위한 패키징 기술로 구성된 표준인EPUB3가 국제표준기구인 ISO/IEC에서 국제표준으로 채택됨에 따라 시장 표준이 공적 표준으로 통합되는 현상이 전자출판 분야에서도 뚜렷이 나타나고 있다. 본고에서는 전자출판 표준인 EPUB3을 교과서 등 교육용 교재, 참고서, 학습서 등 교육 분야에 확대 적용하기 위하여 온라인 평가 서비스, 학습용 소프트웨어 연계, 교육용 메타데이터 활용 등 이질적인 기술 들 간의 융합이 어떻게 이루어져야 하는지에 대한 방향을 제시한다. 이러한 노력은 지난 2013년부터 국제 표준화 단체인 IDPF(International Digital Publishing Forum), IMS Global Learning Consortium, World Wide Web Consortium이 구성한 EDUPUB Alliance를 통해 구체화되고 있다. 따라서 향후 어떠한 구체적인 주제의 논의가 국내에서도 필요한지 알아본다. 또한 디지털 교과서와 학습 교재는 모바일 및 온라인 학습환경에서 다양하게 활용될 수 있으며, 학습자가 생성하는 학습 데이터를 체계적으로 수집하고 분석한다면 학습결과를 향상시키는데 큰 기여를 할 수 있을 것으로 기대한다.
