Currently, the market of digital contents such as e-books, cartoons and webtoons is growing up, but the copyrights infringement are serious issue due to their distribution through illegal ways. However, the technologies for copyright protection are not developed enough. Therefore, in this paper, we propose the NSS-based publication classification method for copyright protection. Using histogram calculated by NSS, we propose classification method for digital contents using SVM. The proposed algorithm will be useful for copyright protection because it lets us distinguish illegal distributed digital contents more easily.

Most software is distributed as a binary file format, so reverse engineering is not easy. But Android is based on the Java and running on virtual machine. So, Android applications can be analyzed by reverse engineering tools. To overcome this problem, various obfuscation techniques are developed. In android environment, the Proguard is most widely used because it is included in the Android SDK distribution package. The Proguard can protect the Java source code from reverse engineering analysis. But it has no function to protect resources like images, sounds and databases. In this paper, we proposed and implemented resource obfuscation framework to protect resources of android application. We expect that this framework can protect android resources effectively.

In copyright rights of the digital image, copyright holders need to protect copyrights and improve the improvement of copyright laws through accurate understanding of copyright laws, and also to improve the effectiveness of copyright rights of copyright holders and the effectiveness of users' rights. First of all, the scope of the study is based on the case of recognition of the scope of the identity of the same scope and the copyright on the copyright law of the digital image, and the application of the image of the image of the image-writing image and the use of image artifacts based on the image copyright classification system suitable for the user's application.

Computational creativity is a field of artificial intelligence research to replicate creativity of human beings, creating works in various fields or helping human authors. The copyright of works produced by computational creativity has not been established in most countries yet, however, there will be the need for systems to protect the copyrights with the development of the technology in the future. In this paper, we propose a copyright protection system based on blockchain technology that protects the copyright of various contributors contributing to the creation of computer creative creativity, and transparently and safely records the contribution of copyrighted works. The proposed system records the contribution of all related works from the machine learning of computer creativity to the creation of the final work on the blockchain so that it is possible to establish quantitative evaluation criteria for the copyright when the future copyright law system is revised.

There are scattered various kinds of software and digital contents around modern peoples. Most of peoples do not realize the importance of the problem related with rights protections of software and digital contents that most of peoples are acting illegal use or illegal copy of software or digital contents without any sense of guilt. In this paper, we carry out a survey targeting IT department majors and non-IT department majors about their aware of rights of software and digital contents and then we suggest a problem from the results of a survey and study a solution for advancing problem of aware of rights. The most effective solution of aware improvement of rights is continuous and repetitive education concerning rights. Also, Reasonable prices that should makes for paying cost of copyrights by users.

With the development of the IT industry and the increase of cultural activities, the demand for works increases, and they can be used easily and conveniently in an online environment. Accordingly, copyright infringement is seriously occurring due to the ease of copying and distribution of works. Some special types of Online Service Providers (OSP) use filtering-based technology to protect copyrights, but they can easily bypass them, and there are limits to blocking all illegal works, making it increasingly difficult to protect copyrights. Recently, most of the distributors of illegal works are a certain minority, and profits are obtained by distributing illegal works through many OSP and majority ID. In this paper, we propose a profiling technique for heavy uploader, which is a major analysis target based on illegal works. Creates a feature containing information on overall illegal works and identifies major heavy uploader. Among these, clustering technology is used to identify heavy uploader that are presumed to be the same person. In addition, heavy uploaders with high priority can be analyzed through illegal work Distributor tracking and behavior analysis. In the future, it is expected that copyright damage will be minimized by identifying and blocking heavy uploader that distribute a large amount of illegal works.

One of the main goals of providing open access is to vitalize the exchange of academic information by allowing access to the scholarly research outputs for everyone without the legal, financial, and technical barriers. We regard the use of the institutional repository as an open access enabler. In this study, we tried to make the factors, which enable the successful deployment of the institutional repository, explicit. We utilized literature review and case studies to generate the potential success factors for the institutional repository deployment. We verified the factors by having in-depth interviews with the subject matter experts. The resulting factors were organized as organizational, political, and technical ones. The organizational factors included the strong open access support by the organization heads. Under the policy factors, a number of issues such as selection of the core contents, minimum quality control, protection of the copyrights, forming supporting groups through active advertising, long-term preservation, incentive, and mandate, were included. The technical factors included easy submission, support for interoperability, and support for the publication activities.

This paper proposes a novel watermarking algorithm that protects digital copyrights and is robust to attacks. Watermarks are embedded in the subband including the significant part of the signal such as a pitch. Generally, the subband containing the pitch has the biggest energy. In order to find this subband, wavelet packet transform is used to decompose the subbands and their energy are calculated. The signal of the selected subbands is transformed in frequency domain using FFT. The watermarks are embedded using QIM for samples higher than a certain threshold. The blind detection uses the Euclidean distance. The proposed method shows less than 5% BER in the audio watermark benchmarking.

In order to secure the compatibility of eBook viewers based on EPUB 3.0, IDPF launched an open project of Readium in February 2012, which supports the standard platform for eBook viewers and the related SDK that can be implemented on different OSs. The current EPUB standard, however, does not provide DRM standards to protect eBook copyrights. Therefore, the compatibility of Readium SDK cannot be secured. Even though the Readium project has tried to design a standard reference software in order to apply DRM independently of EPUB standards, it still does not definitely solve compatibility problems of plural DRMs. This paper suggests a compatibility model based on Readium SDK and ContentMudule technology, in which eBook viewers can work together with plural DRM technology.

This paper aims to develope the technology for monitoring and identifying webtoon works that are being illegally distributed through the web-hard, torrent and overseas websites. The technology is to effectively prevent the illegal distribution and protect the copyrights of the webtoon works, leading to create a healthy market. This paper deals with the technology for (a) automatic collection of webtoon works from the webtoon service sites, (b) extraction of the features from the images of the collected webtoon works, and (c) registers them in the feature database. For these purposes, the required system performance and features were analyzed and the structures of webtoon service sites were examined, through which the system for automatic registration of webtoon works and features was developed. The system can work for the early stage blockage of illegal distributions of webtoon works which occur during the period from webtoon posting to feature registration.
