The development of artificial intelligence technology and the shift to a software-driven society are raising the need for digital literacy education on how to access, understand, use, create and share new open content in a variety of sustainable open content. At this point in time, this paper defines the digital literacy as the subliteracy concept for data, tools, and device elements. It is defined as a concept that includes cognitive and non-cognitive abilities and is stratified by computer literacy, ICT literacy, and information literacy. Open content is also defined as teaching-learning materials that can be used and shared freely by anyone, such as the Open Education Resource (OER) and the Open Access movement. Based on the two definitions, a three-step strategy for digital literacy education was developed to select open content in the digital environment, followed by a digital literacy education plan, and finally, an education frame to foster digital literacy capabilities.

The usage of DRM-applied digital contents reduces user's convenience, thus it leads the many users to avoid using DRM-applied digital contents. In this paper, therefore, we propose the new distribution model in which the users, who purchase the DRM-applied digital contents, can resale freely those contents to the other users. As a result, the proposed model induces the users to distribute contents soundly by including them in one of distribution objects. For the purpose of this, in this paper, we propose that a packaged content and usage rights are transferred to another user by using a method which based on some existing digital ticket or coupon. In addition, the security of the proposed system is discussed for the double transfer, the forgery and the modification of usage rights, and the reproduction of contents and usage rights.

For the domestic digital contents, a proactive cooperation system or framework between the government, the businesses and research institutions, which would allow for free flow of interaction among these players, can play that role. We have proposed and realized the Dynamic Coordinating Framework(DCF) to bridge these gaps among the major players in the industry. The the Dynamic Coordinating Framework rests on the following major functions. The first major function of the DCF is to decipher any ambiguity that may be embedded in external inputs by stratified role and bias. The second function is to create cooperative groups that will deal with the ambiguities based on its consequent situation. The third is a feedback function that will draw out a new cooperative way by re-feeding the capacities and the conflicts that stem from the existing organizations and strategies into cooperation and adjustment process. Our DCF has compared and evaluated with England and Australia digital content industry models under AHP(Analytic Hierarchy Process) method. DCF has turned out to be well designed and have strong points based on OECD innovation and cooperation criteria.

An electronic commerce model is proposed which distributes digital content in mobile environment. This model resolves the problems caused by various digital content and complex distribution structure. The online distribution systems under the wireless environment include many different factors from the conventional offline and wired networks. Furthermore, the multimedia content may be propagated more easily and illegally. The scheme to protect the rights and profits of people related to the copyrights of digital content is needed. In this paper a framework for electronic commerce of content distribution under the wireless environment based on MPEG-21 is proposed. This model can be applied to the digital rights management system and utilized to protect the rights of trading entities in online distribution of electronic commerce.

In this study, the intellectual property rights of digital contents (creations) are protected by using block chain technology that cannot be damaged or forged. So, we build a blockchain-based content sales revenue tracking system and platform that activates the transaction and distribution of digital content (creation). We developed an API server that can be used for content registration and revision history management smart contract, license management smart contract according to content purchase, content inquiry function through files and hashes, and web and APP services. Through this, it is possible to prove the relationship between the rights of the creators of digital content creations and protect the rights of the creators.

As for the digital content, a reproduction is easy and manuscript is identical with original copy. Because of these characteristics, there are difficulties on prevention of an illegal reproduction and an illegal currency. In recent days various digital content service systems based on a web are commercialized. An appropriate copyright protection technology is required so that these systems develop as a profit model. Generally we use encrypted digital content transmission method for the copyright protection on a web base system. At the time of this, it is increased sire of encrypted digital content. As for this, it be increased time required on an execution process. Therefore, a design of the system that considered a execution time and a security is required. In this study, we designed the digital content transmission system that considered execution time and a security through a partial encryption based on a digital content copyright management technique. Also we evaluated performance of a proposed system through analysis.

The number of digital content used in mobile devices such as smartphones or tablet PCs has been rapidly increasing along with the development of IT industry. At the same time, studies on digital content management are actively conducted. One of the previous studies defined CTI(Content Tracking Information) for efficient management of the information on digital content usage between mobile devices in an area in which the internet is inaccessible, and suggested ways to deal with CTI management, reduction of the overhead and a technique of collecting as many CTIs as possible within a short time. This paper presents the design and implementation of a simulator capable of verifying the logic and the performance of the CTI management method. This tool simulates a mobile environment where devices move around in the internet inaccessible area and propagates digital contents each other. It shows several advantages including the efficient synchronization of CTI management and overhead reduction.
