Radio-Frequency Identification (RFID) or Near Field Communication (NFC) technology has many advantages over other visual interfaces since it does not require line-of-sight alignment, can identify multiple tags simultaneously, and does not destroy the integrity of original objects. In addition, smart devices such as smartphone and smartpad have NFC/RFID readers which can provide mobile and natural interactions with digital and physical contents. Augmented reality has an excellent visual interaction capability with digital contents in a real environment by embedding digital contents into the physical world. In this paper, we propose a new approach to digital content interactions using RFID/NFC-based tangible interfaces in augmented reality environments that utilize invisible interfaces in addition to marker-based visual interfaces. By combining the advantages of invisible and visual interfaces, more intuitive interactions with digital contents can be provided, which can remove the difficulty of using typical AR paddles that are widely used in AR interactions. In particular, a semantic AR ontology is defined to provide more convenient interactions. Through the semantic ontology-based inferencing, physical querying and filtering are effectively supported. We will show the effectiveness and advantage of the proposed approach by demonstrating implementation results.

To make the DRM technology protect adequately the copy right of digital contents, DRM software should have high quality and no defects when DRM is added to digital contents. It can be a basis for the effective protection of the copyright of digital contents to develop a quality evaluation model of DRM SW. First of all, the security of DRM SW is the most critical quality characteristic that DRM software must have. In this paper, we conducted research on how to measure the quality of security of DRM SW.

This paper proposes a method to manipulate digital hologram contents by manipulating and/or synthesizing the depth information. To synthesize digital holograms themselves in order to create new digital hologram contents. This paper uses both the depth information obtained by converting the disparity information by using a stereo matching method and that obtained by taking pictures with a depth camera. In addition, assuming that digital holograms are created using the computer-generated holography method, we propose a technique for authoring and compositing hologram contents by using either the changes in the three-dimensional positions of objects in the hologram or by combining the objects with other contents by means of changes in the depth information. Further, more than one digital hologram was synthesized to form a hologram. The reconstructed result from the synthesized hologram also contained all the objects in each digital hologram before synthesis at the same positions and distances.

Digital contents market has been drastically increasing under Clouding Computing and Smart Phone environment. The Contents industry is going to be more essential portion than manufacture or service industry in the near future. One good example of high value-added contents is the Harry Potter series which exceeds 10 years' net profit of Hundai automobile company. This one example shows us very well that digital contents market as a core-engine for culture industry development is economically influential and attractive as well. This study focuses on activation of Digital Copyright Exchange in knowledge service convergence era. First, it examines other services like stock exchange, electronic documents and authentication certificate etc. which are similar to DCE service. Then it analyzes what factors make copyright industry have interested in the DCE the through technology acceptance model. Based on the results of the analysis, finally, this study evaluates how the DCE contributes to copyright industry overall including fair utilization of works.

The purpose of research is to investigate patterns and diffusion of consumer participation on Internet UCC based on digital contents services. A sample survey of internet users was conducted, responses were collected from 629 respondents and consumer streaming data were analyzed. Some of the practical implications of the results are follows. Research can find out that patterns of user participation in UCC. The major genres of UCC are like daily lives of individuals, humors, parodies of star entertainers and types of contents like still pictures or images, texts are relatively highly generated comparing with multimedia UCC. Although participants have been being increased in UCC recently, the consumers as prosumers who are classified in contents generating group are ten percents at the most. In generating community-based UCC such as posting answers of questions and activities in Blog, prosumers who are in contents making group(recreational group) show more positive attitudes than simple participants(consuming only). The results of multiple regression analysis indicated that fun & entertainment, arousal, self-expression, user friendly web interface variable commonly posited a significant effect in multimedia UCC Services between two groups. Information sharing and perceived usefulness posited a significant effect in recreational group.
