Digital content industry is growing rapidly because of the property of high-speed networking and greater demand for digital fulltext-image. However, we know the fact that it is many difficulty in production and supply for good quality of content. Hereupon, we suggest digital fulltext-image service framework to protect copyright. More concretely, we propose integrated model and reference model to securely serve digital fulltext-image by recompositing core objects and reconstructing the value-chain structure of digital content industry to framework including the process(from its production (creators or copyrighters) to consumption (users or consumers)). Also, we construct the digital fulltext- image service system based on reference model and reconstruct its interface that occurs between core subjects.

In order to guarantee the compatibility of e-Book viewers based on EPUB 3, IDPF launched Readium SDK v1.0 in January, 2015, which was followed by research on the implementation of Readium LCP specifications for user-friendly DRM functions. The complexity of the Readium SDK, however, makes difficulties in interlocking Readium SDK with LCP modules. Moreover, from the perspective of the Readium SDK, which tries to maintain the architecture, independently of any specific DRM technologies, the strong interlock with LCP, as a one DRM, is not desirable. This study represents a Content Protection Framework Model for compatibility of Readium-SDK-based e-Book DRM in order to hide the complexity of Readium SDK and implement an easy interlock between plural DRM and Readium SDK.

As networks increase and cross-convergence occurs between various types of devices and communications, there is an increasing demand for interoperable service in the business environment and from end users. In this paper, we investigate interoperability issues in the digital rights management (DRM) and present a practical framework to support interoperability in environments with multiple devices. The proposed architecture enables end users to consume digital content on all their devices without awareness of the underlying DRM schemes or technologies. It also enables DRM service providers to achieve interoperability without costly modification of their DRM schemes.

After more 60 years' legislative practice of water resources protection, the Chinese government has initially established a legislative system of water resources protection, based on Water Law. From the development course of water resources protection legislation, the paper mainly analyzes the legal framework, main content & management system of water resources protection, and pointed out the improved direction of water resources conservation legislation in China in the future.

Research on the Development of EPUB SCP(Secure Content Protection) Technical Specification and International Standardization has been carried out as a R&D project granted by the Korea Copyright Commission since 2014. The research aims to build a standard framework for the EPUB DRM(Digital Rights Management) based on the Readium LCP(Licensed Content Protection) and KS EPUB DRM specifications, to develop element technologies for the framework, and to standardize it as an IDPF(International Digital Publishing Forum) industrial standard. One of the essential features of the EPUB DRM developed though this study is to support the lending model of the digital library. This paper introduces LSD(License Status Document) specification which is a DRM license management protocol for the digital library lending process, and also represents a model which can automatically test the implemented entities of the LSD specification, test scenarios and test materials.

As the broadcasting and communications are digitalized, future broadcasting can provide us new services and content which we have never experienced before. For the services, the development of high-quality content is important as well as the development of efficient technologies. However, if there are no proper methods for protecting and managing content, we can hardly expect the creation of high-quality content to be flourished because much money, time and endeavor should be paid in producing high-quality content. Many activities are under progressing for the protection and management. However, the activities mainly concern general Internet environment which doesn't fully reflect the characteristics of broadcasting. In this paper, we provide a framework model for the protection and management of broadcasting content. First, we analyse the functionalities that must be satisfied in the broadcasting, and we propose a framework model.

With the emergence of increasingly complex networks and diverse user terminals, demand for the next generation IPTV service is rapidly growing. It enables any content to seamlessly be reused on the diverse terminals as well as be broadcasted in real-time through the complex networks. In this paper, a novel security framework is proposed for the real-time and reusable IPTV services. The proposed framework is advantageous over the conventional content protection techniques in easily producing the scalable content with lightweight, perceptual, transcodable, and adjustable security features. It does not only ensure end-to-end security over the entire service range based on a single security mechanism, but also can control a level of security while dynamically transcoding the original content. This approach basically performs selective encryption during and after the compression using scalable video coding. The suitability of the proposed approach is demonstrated through experiments with a practical service scenario. Therefore, it is expected that security technology alone could practically contribute to creating new business opportunities for IPTV services.

There have been proposed various copyright protection protocols in network-based digital multimedia distribution framework. However, most of conventional copyright protection protocols are focused on the stability of copyright information embedding/extracting and the access control to data suitable for user's authority but overlooked the privacy of copyright owner and user in authentication process of copyright and access information. In this paper, we propose a solution that builds a privacy-preserving proof of copyright ownership of digital contents in conjunction with keyword search scheme. The appeal of our proposal is three-fold: (1) content providers maintain stable copyright ownership in the distribution of digital contents; (2) the proof process of digital contents ownership is very secure in the view of preserving privacy; (3) the proposed protocol is the copyright protection protocol added by indexing process but is balanced privacy and efficiency concerns for its practical use.

The growth of digital content market inducted to develope consuming device of various content, and through this, digital content consuming is more Promoted. AXMEDIS(Automating Production of Cross Media Content for Multichannel Distribution) offer various digital broadcasting solution via AXMEDIS Framework for supporting consumption of digital content on various platform. AXMEDIS Framework use cryption tool for protecting and consuming of digital content on device. But, cryption tool management is impossible on device, because of flexible transfer of cryption tool can't be supported between device. In this paper, we designed and implemented transfer module of AXMEDIS cryption tool for flexible operating protection and consumption of digital program on AXMEDIS Framework.

As both a digital camera and a digital camcorder are popularized in recent years, UCC created by general users is also popularized. Unfortunately, according to that, the lack of privacy is also increasing more and more. The UCC is saved on the recordable media(Media) like DVD and deposited personally as well as distributed through Internet portal service. If you use Internet portal service to put up your contents, you can partially prevent the violation of privacy using security technologies such as authentication and illegal copy protection offered by internet portal service providers. Media also has technologies to control illegal copy. However, it is difficult to protect your privacy if your Media having personal contents is stolen or lost. Therefore, it is necessary to develope an additional security mechanism to guarantee privacy protection when you use Media. In this paper, we describe AACS framework for Media Security and propose improved AACS framework to control the access to personal contents saved on Media.
