PurposeThis paper aims to present the semantic content identifier (SCI), a permanent identifier, computed through a linear‐time onion‐peeling algorithm that enables the extraction of semantic features from a text, and the integration of this information within the permanent identifier.Design/methodology/approachThe authors employ SCI to propose a mechanism for simultaneously checking the authenticity and degrees of similarity between different information objects, and present an empirical investigation of the method. A management scenario for the control of the authentication process and the detection of the degree of violation of documents is proposed.FindingsSuch a mechanism could be adopted as a component of libraries' strategy for the protection of the copyrights for documents published on the web.Practical implicationsThe use of the proposed numeric code can be utilised efficiently as a constituent part of the digital object identifier (DOI) system, making its computation more efficient and meaningful.Originality/valueThe identifier proposed in the paper can result in a more efficient index for identifying and retrieving objects in a digital library, as well as online repositories and commercial applications that can handle information retrieval requests more effectively.

A digital object identifier refers to diverse technologies associated with assigning an identifier to a digital resource and managing the identification system. One type of implementation of a digital object identifier developed by the Korean Government is termed the Universal Content Identifier (UCI) system. It circulates and utilizes identifiable resources efficiently by connecting various online and offline identifying schemes. UCI tags can contain not only identifiers but also abundant additional information regarding contents. So, researchers and practitioners have shown great interest in methods that utilize the two-dimensional barcode (2D barcode) to attach UCI tags to digital contents. However, attaching a 2D barcode directly to a digital content raises two problems. First, quality of the content may deteriorate due to the insertion of the barcode; second, a malicious user can invalidate the identifying tag, simply by removing the tag from the original content. We believe that these concerns can be mitigated by inserting an invisible digital tag containing information about an identifier and digital copyrights into the entire area of the digital content. In this study, to protect copyrights of digital contents securely without quality degradation, we attempt to discover a sequence of process for generating a 2D barcode from a UCI tag and watermarking the barcode into a digital content. Such a UCI system can be widely applied to areas such as e-learning, distribution tracking, transaction certification, and reference linking services when the system is equipped with 2D barcode technology and secure watermarking algorithms. The latter part of this paper analyzes intensive experiments conducted to evaluate the robustness of traditional digital watermarking algorithms against external attacks.

The role of digital content identification system is being considered as a useful solution for the content management system and service system. Integrated Copyright Number(ICN), only one domestic identifier to the managing of copyright, can provide the service model in the copyright industry, because it include the information of copyright between the creator and the service provider on the digital work. Universal Content Identifier(UCI), has developed on the focus of digital content service, is somewhat lacking on the copyright management, but it is expected that systematical management and distribution system for copyright and digital work to be able to build as that make up for disadvantage with each identifier's advantage by UCI associate with ICN. In this context, This article can suggest the efficiency integrated structure and the service scenario. Therefore it is contribute to the efficient using and the effective running in the digital identification system. 키워드: ICN, UCI, 식별체계, 디지털저작물, 저작권 ICN, UCI, identifier system, digital content, copyrights * ** *** 본 연구는 저작권위원회 표준화과제 지원으로 수행되었음. 한국디지털콘텐츠산업협회 사무국장(oshosh24@gmail.com) (제1저자) 한국저작권위원회 유통진흥팀장(jjlee@copyright.or.kr) (공동저자) ■논문접수일자:2009년 8월 17일 ■최초심사일자:2009년 8월 20일 ■게재확정일자:2009년 9월 2일 ■정보관리학회지, 26(3): 317-333, 2009.

In this paper, we propose a scheme to associate content-based video signature with Universal Content Identifier (UCI) system of broadcast content for copyright identification and management. Note that content-based video signature can identify a previously distributed content since it is directly extracted from content itself without allocation process of identifier such as UCI. Thus, we design the schema of UCI application metadata, which provides a video signature in order to consistently maintain a systemic link between UCI and the video signature. Also, we present the scenarios of copyright identification, management and additional service, which are based on transmission and management mechanism of video signature with UCI identification system.

Content addressing is one of the basic issues while design of CAN architecture and solution. The paper is devoted to the problem of choice of identifier format, length and characteristic. Basic assumptions of CAN as one of Parallel Internets in IIP (Inzynieria Internetu Przyszlości) project are presented and requirements for content identifier are shown in this context. Discussion of possible solutions is presented and proposal of final identifier format is provided.

Nowadays, content management systems (CMSs) have been adopted by many different types of organizations to manage digital contents, but the increasing complexes and independency result in CMSs falling short of their ideal responsibilities. Interoperability and data redundancy are two issues we should solve, which are caused by adopting diverse metadata systems in CMSs. In this paper we propose a framework to provide abilities for uniformly accessing and managing multiple CMSs in a metadata integrated manner. Afterwards, accounting for reducing data redundancy and the convenience of customers, an unified content identifier (UCID) generation algorithm is proposed and successfully integrated with the metadata management.

The goal of Digital Rights Management (DRM) technology is to distribute digital contents in a secure manner that can protect and manage the rights for all participants in contents distribution value-chain including producers, providers, distributors, and consumers. In most existing DRM schemes, rights are granted per content to a consumer, and all the right-granting information including consumer identifier, content identifier, content decryption key and usage rules are tightly related and stored in the license. However, these schemes cause the problems that the license management will become complicated in proportion to increasing the number of contents or consumers, especially in large-scale content distribution scenarios. In this paper, we propose an efficient Right-granting Model with Hierarchical Group Rights (RMHGR) which can grant rights on some group of contents to a group of consumers. Furthermore, we propose a corresponding DRM system model which differs from previous DRM systems in terms of packaging mechanism, license structure, and content decryption key generation method. A comparison with other DRM schemes has shown that our proposed scheme is low overhead, scalable, and efficient for large-scale content distribution.
