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.

Technical treatments of image contents on the web include the copy protection method such as the image capture protection technology and the traitor tracing method to detect unauthorized duplications through watermarking insertion or feature information technology. However, these two methods have their own weaknesses. The image capture protection method is unable to protect illegal captures when the URLs of image sources are exposed. The traitor tracing method is fundamentally unable to protect illegal captures due to its post-treatment method. Besides, the weakness of using the copyright information display technology involves easy removal of copyright information from copyrighted contents. This paper suggests a model of the web image contents protection system which makes it hard to separate copyright information from web image contents and allows image contents to be shown only in the authorized websites.

Digital contents is used already in near place with us. Contents of MPEG-4 standard is used to process multimedia data in field of communication, computer, broadcasting mobile etc. However, absence of copyright management and protection system and interoperability problem of right system between each corporation happened. Because MPEG establish IPMP(Intellectual Property Management and Protection) system standard in agreement with MPEG-4 system standard, proposed cooperation method to manage and protect copyright. Accordingly, in this paper, put in copyright of authorized contents management and protection extension system implementation adding MPEG-4 IPMP system like plug-in into existing MPEG-4 authorizing tool. Therefore, author edits IPMP information to protect contents or object, and process the information in system and authorize MPEG-4 digital contents that have management and protection sign according to IPMP standard. This system designed and implemented to divided into IPMP information save processor, IPMP information creation processor, media IPPM processor, XMT-A to MP4 converter IPMP extension.

The purpose of this study was to examine the factors influencing copyright protection decision-making among Korean eSports game users. Data collection was conducted over a month at an eSports arena located in Seoul. Of the surveys collected, 354 valid data (88.5% of response rate) were analyzed in SPSS Ver. 20.0 through descriptive statistics, correlation and multiple regression analysis. The results showed that copyright protection decision-making regarding eSports contents was significantly influenced by legal/moral norm, perceive group norm, and past habit/behavior. Among the factors, legal/moral norm was found to be the most influential on copyright protection decision-making.

This study is intended to provide more secure contents authentication and user authentication by applying public key algorithm and hardware binding to the DRM system. The proposed system is capable of protecting distributed contents and copyrights as well as resetting any interoperability issues among those involved in transparent and secure contents distribution. The proposed algorithm also affords transparency in the DRM distribution system and protection from unauthorized distribution.

Wisdom contents is made by an ordinary person and contains life tips helpful in general. As the existing copyright management systems are designed for the corporate or professional authors, it's not easy to use and requires high cost for the ordinary person to get the copyright. Blockchain based system can notarize the block of transactions without help of trustful third party such as existing copyright protection center. Thus, blockchain based copyright protection model is needed to protect the ordinary author's copyright. In this study, we propose the smart contract based copyright protection model which run on the blockchain network. The proposed model consists of smart contract creation, contents purchase and profit sharing stages. The digital signature scheme is used to get the contract agreed by the seller and the author. The smart contract stores the author information, contents information and the percentage of the share as states. If the contents is sold, the sales tokens are redistributed to the author and the seller according to the share. The proposed model can be applied to the ordinary person's copyright registration and management for Wisdom contents distributed in cafe, blog, YouTube, etc.

According to the IT839 strategy which was announced by the Ministry of Information and Communication(MIC) in 2004, the convergence trend of the broadcasting and the communication would be much more promoted. Thus, the methods for protecting the broadcasting contents will be indispensible elements for the successful IPTV service achievement. This paper describes the characteristics of IPTV and the related contents protection techniques. To evaluate several security issues, we suggest a security model for IPTV, and speculate the most widespread, two security technologies for IPTV such as CAS and DRM. Moreover, candidate models of IPTV protection system are suggested based on these technologies.

Currently the copyright law and the online digital contents industry development law aim to protect the producers of databases and digital contents. A report on databases in the United States describes that an additional protection of databases is needed as databases get more significant in terms of science and economy and become a key factor on Internet. At this moment, Korea does not recognize the importance of databases of science and technology when we look into any public or civil organizations. Accordingly this paper deals in depth with overall issues surrounding the regal protection of science and technology databases, key contents for science and technology databases protection by current laws, and additional protection problems. Considering that the industry of science and technology databases plays a pivotal role in the securement of national competitiveness, the preparation of legal measures to properly protect databases as one of the policies for the continuing development of databases should not be overlooked.
