Among human intellectual creations, the right granted by law to what is worth protecting is defined as intellectual property rights. Copyright is a legal right to creative finished products made by individuals, and in recent years, this legal right has been recognized as very important. In other words, copyright is a system created to protect the rights of individuals who created creations and to recognize their efforts. Works subject to copyright vary from poetry, thesis, novels to designs, paintings, music, and architecture, and the scope of the subject is gradually expanding. Recently, research has begun on how far the Metaverse design area absorbed into the real world among works. Computer-generated video productions and software program works are also subject to digital copyright protection, but it is also true that the interpretation of the author protection law for works, designs, and trademarks in the virtual world is unclear. This study aims to analyze copyrights based on case studies and theoretical backgrounds on copyright protection and to discuss the protection limitations of Metaverse design in the virtual world. In other words, the direction for the protection of Metaverse design is presented through clear distinction and definition of copyright protection in the tertiary virtual world. This study aims to present methods for design copyright protection in the era of Metaverse, respect copyright holders' creative activities, and develop our culture through protection of creations.

In this paper, we propose a removable logo watermarking technique for copyright protection of digital image. Then, visible logo is inserted into digital image to protect copyright, and the information removed by the logo is embedded by a new quantization watermarking. In a legal usage, the image can be reconstructed without logo after watermarking detection process. Experiment results show that the proposed method maintains high image quality in both watermarked images and reconstructed images, and is practical and effective in protection of image copyright.

A digital content have been utilized extensively without being limited to one territory of communication, computer, broadcasting, Mobile etc. A digital contents industry have been raised to a key point industry of a knowledge information society. An information infra setup of a global unit was processing to the development of Internet therefor copyright protection a digital contents and system for the officer have been desired. Like this, according as digital contents do fetters to MPEG-4 is circulated, copyright problem was risen. So, people had a lot of interests to protect and manage copyright. Hereupon, MPEG of the IS0/IEC established IPMP(Intellectual Property Management and Protection) standard, and supplements and corrects continuously standard. Therefore, existing system does fetters to MPEG-4 need system that process IPMP information. Hereupon. in this paper, designed system module that is processed by IPMP extension standard that progress now, and embodied copyright protection and management system that user can insert and update IPMP information efficiently within whole or specification part of MPEG-4 digital contents.

When the owners of the intellectual property rights of digital content have lost control over it in the digital environment, there emerged fears that the intellectual property laws, especially copyright law, would not be effective as in the material (Offline ) world. The reason is that the digital environment helps to reproduce copies in high quality and at almost no cost, while copyright law protection has been limited to programs embedded in CDs. According to copyright laws, the owner of the program did not have the right to prevent buyers of the initial physical copy of the program from copying and reselling it to more than one individual without the permission of the original owner. As a result, business owners have invented the idea of licensing digital content and programs instead of selling them. They set out terms that serve their commercial interests regardless of their abuse to intellectual property laws or even the rules of the traditional contract to sell a material property. The abuse has resulted from the way those terms are concluded and the heavy rules that are unfair to consumer rights. Therefore, business owners insisted on dealing with the website and its programs and digital content as material property. Here raises the question of whether the website and its digital content are subject to the protection of copyright law or the rules of the traditional contract or licensing contracts. As the answer to this question affects the protection of consumer rights, is it possible to find a balance between it and the protection of the owners of digital programs' rights.That is what we will discuss in this paper.

The importance of software industry is rapidly increasing with the growth of Internet and the advent of digital economy. The purpose of this study is to research the impact of the copyright protection for securing producers and enhancing of producing on social welfare. The Korean government reformed the copyright law to enhance the copyright protection in 2000 and intensely controlled software piracy in 2001. However, copyright protection has much controversy in aspects of hindering social use of software. This study compared and analyzed the general equilibrium and the copyright protection for social welfare maximization in two cases when network externality exists or not, by assuming the simple demand and supply functions.

Over the last few years, digital audio watermarking has become an interesting issue In many application areas, including digital broadcasting. This is primarily motivated by a need to provide copyright protection of digital audio content. Digital watermarking is a technique to embed copyright or other information int? the underlying data. Several possible audio watermarking techniques have been developed including spread spectrum watermarking, echo watermarking, phase coding, and patchwork. In this paper, we describe some requirements of digital audio watermarking as a tool for copyright protection of broadcasting content, and compare popular audio watermarking algorithms in some significant aspects.

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.

High-quality digital broadcasting contents are susceptible to illegal copy and unauthorized redistribution, which makes broadcasters difficult to protect valuable media assets. So, broadcasters and content providers need the technology for copyright protection of professional digital content. Digital watermarking technology is one of the most actively developed solutions for the copyright protection. This paper suggests the requirements of watermarking technology in DTV(Digital TV) environment for copyright protection and shows the developed real-time watermark embedding/detecting system for HD(High Definition)/SD(Standard Definition) video and experimental results of the system against watermark attack tests. Our watermarking system meets the watermarking requirements of invisibility, robustness and security of DTV environment.
