Today people adopt various contents from their mobile devices which lead to numerous platforms. As technology of 5G, IOT, and smart phone develops, the number of people who create, edit, collect, and share their own videos, photos, and articles continues to increase. As more contents are shared online, the numbers of data being stolen continue to increase too. To prevent these cases, an authentication method is needed to encrypt the content and prove it as its own content. In the report, we propose a few methods to secure various misused content with secondary security. A unique private key is designed when people create new contents through sending photos or videos to platforms. The primary security is to encrypt the "Private Key" with a public key algorithm, making its data-specific "Timeset" that doesn't allow third-party users to enter. For the secondary security, we propose to use Message Authentication Codes(MACs) to certify that we have produced the content.

In this era of convergence, which is characterized by the integration and combination of technology and industries, broadcasting and communications, offline and online, and devices and services, the content industry is also experiencing rapid changes including inter-genre exchange, the creation of new industries, and customized demand. Specifically, IT-based digital content industries such as the online game, e-book, mobile contents and web portal industries are no longer restricted to the boundaries of video, music and games but are being expanded into the realms of education, medicine, fashion and sports thanks to CT innovation of 3D, CG, AR/VR, VFX, etc. As such, various countries have come to recognize the convergent content industry as a new growth engine that will pick up where the IT industry left off, and are forming policies for its development accordingly. This research aims to optimize the system of content taxonomy which is currently genre-focused and unable to support technological development and convergence, and to discover and select star contents to be rigorously developed with governmental support. In this paper, 20 star contents in 8 areas were selected, and these are expected to create tremendous cultural and economic value through ongoing technological and industrial development.

In this work, the effects of maleic anhydride (MA) content on mechanical properties of chopped carbon fibers (CFs)-reinforced MA-grafted-polypropylene (MAPP) matrix composites. A direct oxyfluorination on CF surfaces was applied to increase the interfacial strength between the CFs and MAPP matrix. The mechanical properties of the CFs/MAPP composites are likely to be different in terms of MA content. Surface characteristics were observed by scanning electron microscope, Fourier transform infrared spectroscopy, and single fiber contact angle method. The mechanical properties of the composites were also measured by a critical stress intensity factor (K_IC). From the K_IC test results, the K_IC values were increased to a maximum value of 3.4 MPa with the 0.1 % of MA in the PP, and then decreased with higher MA content.

As networks increase and cross-convergence occurs between various types of devices and communications, there is an increasing demand for interoperable service in the business environment and from end users. In this paper, we investigate interoperability issues in the digital rights management (DRM) and present a practical framework to support interoperability in environments with multiple devices. The proposed architecture enables end users to consume digital content on all their devices without awareness of the underlying DRM schemes or technologies. It also enables DRM service providers to achieve interoperability without costly modification of their DRM schemes.

This paper researches on the cases wherein the concept of gamification is applied to branded content. Gamification is the application of game elements to non-game fields, and it is being actively utilized in the areas of education, marketing, medical, sports, and shopping. Especially, the concept of gamification is applied to branded content and wherein marketing (advertisements) are expanded into entertainment content. This paper studies the methods on how the concept of gamification affects marketing, and application in the expansion of branded content into entertainment content. To achieve this, this paper looked into the concepts and characteristics of gamification and branded content, and analyzed the methods on how the elements of game (goal, competition, feedback, reward) were applied to five kinds of real cases. Finally, this paper verified that gamification is an efficient method of extending branded content into entertainment content.

The age of digital content mainstream consumers in the era of smart technology is expanding compared to the past. Consumers are taking a leading role in the production and distribution of contents in various forms. At the center of this is a post-modern social structure and space that break down the boundaries among Personal Digital Device, contents, production and consumption as a medium. Content rejects the existence of the same thing in the world. The tendency of the main consumer segment and the provision of post modern storytelling that penetrates it creates a huge industry group with various forms of contents. In order to carry out this study, with analyzing examples of movies, games, and advertisements, we found the fact that the center of content creation for individuals made their unique style, excluding generality. As a result of this research, the relationship between the user-driven digital contents and post modern storytelling have been revised the awareness about the possibility of various convergence in the field of contents production.
