It is issued that protecting and managing a copyright are very important to a digitization of multimedia content. All of these techniques are for developing solution about protection and management of the copyright and media service. These have been at the head of the growth of the whole media service, but cause problems such as a illegal copy and distribution. To solve these problems, researchers are performing many projects. We analyze the trend of a multimedia service IPMP(Intellectual Property Management and Protection), DMP(Digital Media Project), ENTHRONE(End-to-end Qos through Integrated Management of Content, Networks and Terminals), and DRM(Digital Rights Management).

UCC is a key characteristic of so-called Web 2.0 which encourage the publishing of one's own content and commenting on other people's. Nowadays, UCC has become a widely used. Accordingly, problem of copyright become a issue. In this paper, we propose the DRM system for UCC rights protection. The system solve the copyright problem in UCC. Therefore, UCC creator can exert the right of UCC. In addition, if the problem of copyright occur, we can find the illegal user and call a him to account by CE information which is stored in UCC server and have a property that a manufacture of original contents can control the copyright.

The study aims to discuss on legal prospects of digital collections' fair use through an analysis of treaties and legislations domestic and international. Based on analysis of leading researches and literature, it discusses legal principles of fair use and defines digital collections' concept and types. For understanding the actual legal system on fair use, limitations and exceptions of copyrights which are presented in treaties, such as 'Berne Convention for the Protection of Literary and Artistic Works' and'Copyright Convention', each nation's laws, and judicial precedents. Especially, a legal dispute between 'Technische $Universit{\ddot{a}}t$ Darmstadt' and Eugen Ulmer KG, which debates on library's rights for digitizing their collections without the rightholder's permission, is analyzed. As a result, this study analyzes its implications for the improvement of the existing copyright system in Korea.

As the risk of technical leakage is increasing, technology protection support systems for small and medium-sized businesses have gained attention. This paper analyzed the perception gap of the user and policy-maker regarding technology protection support systems. First, to identify key elements of technology protection support systems and construct measurement factors, interviews with experts are conducted. Then, surveys are conducted to analyze the perception differences between the users and policy-makers. Factor analysis and ANOVA have been utilized to analyze survey results. The result shows that the perception gaps exist in the following areas: management system, cost reduction, copyright protection, customer satisfaction, leakage prevention, and awareness. To enhance the effectiveness of technology protection support systems, this paper suggests technology protection support systems should be customized in terms of the company's size and type of busines.

Digital watermarking techniques have been used as one of the means for copyright protection and authentication of multimedia data. Conventional Chinese Remainder Theorem(CRT)-based spatial domain watermarking techniques do not perform well under JPEG compression. However, it is seen that the CRT-based watermarking technique in Discrete Cosine Transform(DCT) domain performs well for JPEG compression. In this paper, an improved CRT-based image watermarking method in the DCT domain is proposed. The proposed method provides better robustness which decreases changes of absolute difference of residues against rounding errors due to DCT conversion and various attacks. Experimental results show that the proposed method has a good robustness against various attacks compared with the conventional CRT-based watermarking in DCT domain.

Due to social distancing caused by COVID 19, music concerts have not been allowed at home and abroad, and it is not known when overseas concerts will be able to resume unless the pandemics calm down, even if they are available. Meanwhile, people consume much more content through online services such as Netflix and YouTube than before. Under these circumstances, the music industry expects the virtual livestreamed performance to restore sluggish live performances again and bring about a digital renaissance. It also leads to the issue of reestablishing a copyright system regarding a livestreamed performance and of preparing a new rate of royalty standards for the use of works in OTT. In addition, a multi-territorial licensing of r ights in musical works is necessary to resolve copyright issues efficiently by applying the same term s to all countries from where the audience comes. In this paper, I examine the legal nature and the decision of copyright fees of performances as an integral part of the music industry.

With the rapid development in network, graphic technology, and digital technology, content industry is emerging as an important industry for new cultural development and economic development. The development in digital content technology has remarkably expanded the generation and distribution of contents, thereby creating new value and extending into a large distribution market. However, the ease of distribution and duplication, which characterizes digital technology, has increased the circulation of illegal contents due to illegal copying, theft, and alteration. The damage caused by this illegal content is severe. Currently, a copyright protection system targeting online sites is available. By contrast, no system has been established for offline companies that sell offline genuine content, which compete with online companies. The demand for content of overseas tourists is increasing due to the Korean wave craze. Nevertheless, many offline content providers have lost competitiveness due to illegal content distribution with online companies. In this study, we analyzed the case and status of similar copyright certification systems in Korea and overseas through previous research and studied a system to certify the offline genuine contents business. In addition to the case analysis, we focused on interviews obtained through in-depth interviews with the copyright stakeholders. We also developed a certification framework by establishing the certification domain, certification direction, and incentive of the certification system for offline businesses with genuine content. Selected certification direction is ethical, open, inward, store, and rigid (post evaluation). This study aimed to increase awareness among consumers about the use of genuine content and establish a transparent trading order in a healthy content market.

Current certification system use serial key for protect copyright of software and digital contents. But It is not efficient system, because It is not protect copyright through create virtual key or use public key. So we research on various cryptology for prevent illegal copy of serial key, but It is not enough protection of copyright that use software technology only. In this paper, we propose certification system using smart card for protect copyright of software and digital contents.

This paper presents a new contents-based digital still image protection method which includes a copyright message. Since the existing method using gradient values used a pixel based $3{\times}3$ Sobel operator, it was sensitive to attacks and could not extract exact copyright message. Therefore, in this paper, we present a algorithm which uses block based OCL(Orientation Certainty Level) instead of pixel. The experimental results show that the proposed scheme not only has good image quality, but also is robust to JPEG lossy compression, filtering, sharpening, blurring and noise. Moreover, the proposed algorithm has good performance more than 10% in rotation attacks than the existing method.

Recently, the distribution and using of the digital multimedia contents are easy by developing the internet application program and related technology. However, the digital signal is easily duplicated and the duplicates have the same quality compare with original digital signal. To solve this problem, there is the multimedia fingerprint which is studied for the protection of copyright. Fingerprinting scheme is a techniques which supports copyright protection to track redistributors of electronic inform on using cryptographic techniques. Only regular user can know the inserted fingerprint data in fingerprinting schemes differ from a symmetric/asymmetric scheme and the scheme guarantee an anonymous before recontributed data. In this paper, we present a new scheme which is the detection of colluded multimedia fingerprint by neural network. This proposed scheme is consists of the anti-collusion code generation and the neural network for the error correction. Anti-collusion code based on BIBD(Balanced Incomplete Block Design) was made 100% collusion code detection rate about the average linear collusion attack, and the hopfield neural network using (n,k)code designing for the error bits correction confirmed that can correct error within 2bits.
