This paper describes our design of a contents distribution framework that supports transparent distribution of digital contents on the Internet as well as copyright protection of participants in the contents distribution value chain. Copyright protection must ensure that participants in the distribution channel get the royalties due to them and that purchasers use the contents according to usage rules. It must also prevent illegal draining of digital contents. To design a contents distribution framework satisfying the above requirements, we first present four digital contents distribution models. On the basis of the suggested distribution models, we designed a contract system for distribution of royalties among participants in the contents distribution channel, a license mechanism for enforcement of contents usage to purchasers, and both a packaging mechanism and a secure client system for prevention of illegal draining of digital contents.

Digital Contents are increasing the modification of the contents by individual user and the modified or copied contents are simply distributed though the ultrahigh speed internet and the negative pervasive effect on the contents market is increasing. The solutions for copyright protection from illegally distributing contents are developing by various standardization groups and contents manufacturers and its commercia use is partly practiced. The MPEG was developing the IPMP technique to apply existed MPEG standards as a way of digital contents protection. However, as these IPMP techniques did not provide a satisfactory function for contents protection, the DMP standard was suggested as an alternative plan. In this paper, the system is designed and materialized to apply the TooIPack concept of DMP which ensure the interoperability of DRM system. With this paper, it is expected that the practical use and the possibility of the DMP standard in the DRM market would be verified and DMP standard may presents as a reference model for more systematic standardization operations.

The MPEG-4 standard is aimed to define an object based audiovisual coding standard to address the emerging needs from interactive broadcasting. Since a broadcasting program is created on the basis of its objects, it is considered that MPEG-4 is most suitable for interactive broadcasting contents production and it can be retrieved in terms of its properties. But, there is no system that protects the copyright of digital contents and manages copyright and possibility that contents producer and author's copyright receives infringement at process that exchange contents mutually rose very. Therefore, we need to control and distribute contents according to user's permission rights. In this paper, we present the authoring system based on MPEG-4 IPMP for copyright and protection of MPEG-4 contents. The main features of the proposed approach is to provide an MPEG-4 compliant IPMP authoring system in a plug-in type along with standardized interfaces, which is to be able to incorporated into an existing MPEG-4 content authoring system. In this way, it is capable of authoring content to the MP4 file format while accommodating protection and management of content in a unified way. Furthermore, it also allows a user to edit and/or author IPMP information in a more efficient way by offering form based user interfaces.

Digital copyright protection is important in the protective side of effort to have leaned to in property right and it which are intelligent of an author and is very important for development of digital contents industry. It is the misgovernment that a reproduction is easy as for the digital contents. and the original and a copy have the same characteristic, and it is so, and is experiencing what is hard for protection of copyright and large quantity illegal copy and illegal distribution prevention. CDN needs a copyright protective plan about the digital contents that digital contents providers were written jointly. The paper used a non-repudiation multi-technique for copyright protection about the digital contents which were written jointly. The Non-repudiation multi-technique proved efficiency about this.

Recently, the studies of contents protection technique are getting popular in the field of internet DRM(Digital Right Management). But, authentication process of digital contents is different from each implementation. Also, protection technique for the contents rights intrusion adapts each other methodologies. We survey the modeling and system of DRM such as DOI, INDECS, MPEG-21, XrML, and OPIMA standard in this paper.

It is issued that protecting and managing a copyright are very important to a digitization of multimedia contents. 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). 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.

Throughout the years, cybersecurity incidents related to the shipbuilding and maritime industries are occurring more frequently as the IT industry develops. Accordingly, expertise in the information protection industry is necessary, and effective education contents on information protection are needed for this purpose. Recently, there have been more and more cases of increasing user experience by applying Metaverse technology to the educational field. Therefore, this study analyzes the existing information protection education and training and the information protection education contents in the maritime industries and proposes four directions for content development (i.e., online education and seminars, cybersecurity threat learning of virtual ships, accident reproduction, and maritime cybersecurity exhibition operation).

In this paper, we proposed and modeled a video contents protection system based on the infectious information hiding(IIH) technique as using characteristics of biological viruses. Our proposed IIH System considered the requisite important information for video contents protection as the infectious virus, and suggested a new paradigm about video contents protection that transmitted infectious information from contents(host) or video CODECs(viral vector). Also, we modeled the Pathogen, Mutant and Contagion virus as the infectious information and defined technical tools about verification of infectious information, kernel based IIH, contents based IIH and creation/regeneration of infectious information as main techniques for our IIH system. Finally, through simulations that carried the infectious information by using conventional information hiding algorithms as kernel based and contents based IIH techniques, we verified possibilities of our proposed IIH system.

There have been researches into digital Watermarking technology or Fingerprinting vigorously to safeguard Protective rights for knowledge and poverty for digital contents. DRM(Digital Rights Management) is not only Protective rights for knowledge and poverty, but also management and systems that are necessary to put out, circulate and use for contents. This paper proposes two kinds of ideas. One is protecting contents from illegal acts such as illegal copies when the contents are in the process of circulation. The other is the protocol that can give users convenience. Hidden Agents are used so that contents are protected from illegal copies and illegal use in the contents and cuts off those illegal acts. The Agent will be installed without any special setup. In addition, it can replace roles of Watermarking as a protection. Therefore, this paper shows the solution of illegal copies that happens frequently.
