  • 블록체인 기술은 '새로운 산업을 만드는 구조'는 아니다. 오히려 과거 인터넷이 도입되면서 사회, 경제 모델 전반이 바뀐 것에 비하면 작은 변화에 가깝다고 할 수 있다. 하지만 블록체인은 높은 보안성과 투명성을 기반으로 기존 산업의 기대 효용을 높여 주고, 다양한 시도를 가능하게 만들어 줄 것이라는 점에서 매우 기대되는 분야이기도 하다. 블록체인은 인터넷 이후의 다른 기술과는 확연히 다르다는 주장을 유심히 살펴볼 필요가 있다. 왜냐하면 블록체인이 인터넷과 우리 사회구조를 어떻게 혁신 시킬 수 있는지, 인터넷 이후의 마케팅 세계가 어떻게 변해왔는지, 소비자는 또 어떻게 변해 왔는지 우리는 쉽게 알 수 있기 때문이다. 이처럼 현재 우리 사회는 "새로운 것을 만들기보다는 효율성과 사회의 신뢰성, 콘텐츠 가치의 투명성을 높여 주는 것이 블록체인의 기술이다"라고 정의할 수 있다. 그렇다면 블록체인 기술의 혁신이 미디어 산업 분야에도 접목되어 새로운 동력으로 작용 할 수 있을 것인가? 이같은 질문과 함께 본 고에서는 블록체인과 콘텐츠 산업, 블록체인과 미디어 서비스 구조, 새로운 서비스 사례 및 기존 스트리밍 서비스, 콘텐츠 제작 및 유통 분야 변화, 그리고 유료 콘텐츠 거래, 디지털 콘텐츠의 효율적인 저작권 관리 분야에서 그 역할과 비중이 어떻게 적용되어 효과가 나타나게 될 것인지에 대해 방송 현업 종사자의 시각에서 살펴보았다. 결국 이러한 신기술을 적극 활용하기 위해서는 블록체인 기술이 갖는 신뢰와 가치라는 근본적인 사항과 미디어업계 종사자들의 긍정적인 인식 변화와 함께 블록체인 미디어 비즈니스 생태계 조성을 위한 연구와 파일럿 적용 등 실험적 여정들이 뒤따라야 할 것이다.

  • This paper developed a secure web-based digital notary system. The system conforms to international standards, and gives users very good accessibility to it. The technologies and the application systems for timestamp-related services are not yet popularized, but they are potentially meaningful to many kinds of areas such as ecommerces, digital right managements, and internet mail systems. The digital notary system uses the timestamp requests and responses which conforms to rfc 3161. The system supports secure communication between web-based notary server and its clients by using SSL(Secure Socket Layer), and use nonces for prevention of replay attacks.

  • In this paper, we propose a new design of circulation system of digital music contents in P2P service. It has functions of contents recognition, management of copyright DB, clearing house to perform payment system of P2P service. In P2P service each user provides his music contents, but in other circulation system, service providers provide their music contents. Therefore it is very difficult for each provider to recognize whatever the quality of distributing contents are good or not. Most circulation systems use hash technology or contents recognition technology for the recognition of contents. For the usability and efficiency this proposed system provides the combining technology of hash processing and contents recognition.

  • The evolution of internet have opened the world of IPTV. With internet protocol, IPTV broadcasts contents stream. The IP protocol doesn't provide secure service due to IP characteristics. So, it is important to provide both connect and secure service. Conditional Access System and/or Digital Right Management are being used to protect IPTV contents. However, there exist restrictions in the view of security. In this paper, we analyse existing security technologies for IPTV and propose a novel method to enforce security efficiently. In the proposed method, OTP is used for encryption/decryption contents and CAS controls key for encryption/decryption and the right of user. With this scheme, it reduces the load of the system and provides more security.

  • According as internet and computer technology develops, the amount of information has increased exponentially, arising from a variety of web authoring tools and is a new web standard of appearance and a wide variety of web content accessibility as more convenient for the web are produced very quickly. However, web documents are put out on a variety of topics divided into some blocks where each of the blocks are dealing with a topic unrelated to one another as well as you can not see with contents such as many navigations, simple decorations, advertisements, copyright. Extract only the exact area of the web document body to solve this problem and to meet user requirements, and to study the effective information. Later on, as the reconstruction method, we propose a web search system can be optimized systematically manage documents.

  • This is a study of the digital archives of Culturecontent.com where 'Cultural Archetype Contents' are currently in service. One of the major purposes of our study is to point out problems in the current system and eventually propose improvements to the digital archives. The government launched a four-year project for developing the cultural archetype content sources and establishing its related business with the hope of enhancing the nation's competitiveness. More specifically, the project focuses on the production of source materials of cultural archetype contents in the subjects of Korea's history. tradition, everyday life. arts and general geographical books. In addition, through this project, the government also intends to establish a proper distribution system of digitalized culture contents and to control copyright issues. This paper analyzes the digital archives system that stores the culture content data that have been produced from 2002 to 2005 and evaluates the current system's weaknesses and strengths. The summary of our findings is as follows. First. the digital archives system does not contain a semantic search engine and therefore its full function is 1agged. Second, similar data is not classified into the same categories but into the different ones, thereby confusing and inconveniencing users. Users who want to find source materials could be disappointed by the current distributive system. Our paper suggests a better system of digital archives with text mining technology which consists of five significant intelligent process-keyword searches, summarization, clustering, classification and topic tracking. Our paper endeavors to develop the best technical environment for preserving and using culture contents data. With the new digitalized upgraded settings, users of culture contents data will discover a world of new knowledge. The technology we introduce in this paper will lead to the highest achievable digital intelligence through a new framework.

  • One of the main goals of providing open access is to vitalize the exchange of academic information by allowing access to the scholarly research outputs for everyone without the legal, financial, and technical barriers. We regard the use of the institutional repository as an open access enabler. In this study, we tried to make the factors, which enable the successful deployment of the institutional repository, explicit. We utilized literature review and case studies to generate the potential success factors for the institutional repository deployment. We verified the factors by having in-depth interviews with the subject matter experts. The resulting factors were organized as organizational, political, and technical ones. The organizational factors included the strong open access support by the organization heads. Under the policy factors, a number of issues such as selection of the core contents, minimum quality control, protection of the copyrights, forming supporting groups through active advertising, long-term preservation, incentive, and mandate, were included. The technical factors included easy submission, support for interoperability, and support for the publication activities.

  • In an IPTV system, the rights of the content and service provider can be protected by using Conditional Access System (CAS) and Digital Right Management (DRM). In case of the CAS, only the authorized user who has structured authentication keys can decrypt the encrypted content. However, since the CAS establishes a secure channel only between content provider and Smart Card (SC), it cannot protect the system against McCormac Hack attack which eavesdrops on unsecure channel between SC and Set-Top Box (STB) and SC cloning attack. In this paper, we propose a robust multi-STB assisted SC / STB authentication protocol which can protect the IPTV system against not only McCormac Hack attack, but also SC cloning attack. The previous works which bind a STB and a SC during the SC registration phase against the SC cloning attack does not support multi-STB environments. The proposed system which dynamically updates the STB information in subscriber management system using the bi-directional channel characteristic of IPTV system can support the user's multi-STB device effectively.

  • In making 3D animation with digital technology, it is necessary to increase productivity and reusability by managing production pipeline systematically through standardization of animation content. For this purpose, we try to develop the animation content management system that can manage all kind of information on the production pipeline, based on SCORM of e-teaming by considering production, publication and re-editing. A scene as the unit of visual semantics is standardize into an object that contains meta-data of place, cast, weather, season, time and viewpoint about the scene. The meta-data of content includes a lot of information of copyright, publication, description, etc, so that it plays an important role on the management and the publication. If an effective management system of meta-data such as ontology will be implemented, it is possible to search multimedia contents powerfully. Hence, it will bring on production and publication of UCC. Using the meta-data of content object, user and producer can easily search and reuse the contents. Hence, they can choose the contents object according to their preference and reproduce their own creative animation by reorganizing and packaging the selected objects.

  • If the blockchain means storing information in a distributed environment that cannot be forged or altered, it is mentioned that this is similar to what librarians collect, preserve, and share authoritative information. In this way, this study examined blockchain technology as a way to collect and provide reliable information, increase work efficiency inside and outside the library, and strengthen cooperative networks. This study attempted to propose various ways to utilize blockchain technology in book relations based on literature surveys and case studies in other fields. To this end, this study first analyzed the field and cases of blockchain application to confirm the possibility and value of blockchain application in the library field, and proposed 12 ways to utilize it based on this. The utilization model was proposed by dividing it into operation and service sectors. In the operation sector, it is a digital identity-based user record storage and authentication function, transparent management and traceable monitoring function, voting-based personnel and recruitment system, blockchain governance-based network efficiency function, and blockchain-based next-generation device management and information integration function. The service sector includes improved book purchase and sharing efficiency due to simplification of intermediaries, digital content copyright protection and management functions, customized service provision based on customer behavior analysis, blockchain-based online learning platforms, sharing platforms, and P2P-based reliable information sharing platforms.
