온라인게임은 부정로그인 및 게임봇 (Game BOT) 탐지 등 서비스에 악영향을 주는 이상징후를 조기에 탐지해야 하는 서비스 분야이다 보니, 데이터기반 보안 (Data-Driven Security)이 상당히 오랜 기간 자생적으로 구축이 되어왔다. 온라인 게임은 초당 동시접속이 800만~1천만에 육박하는 게임도 시장에 빈번히 존재하기 때문에, 게임유저들의 로그데이터를 빅데이터 기술을 접목한 데이터 분석이 필수적이다. 본고에서는 온라인게임 분야에 존재하는 다양한 위협요소 중 하나인 게임봇 및 작업장 탐지에 적용된 데이터기반 보안 기술들에 대해 조사하고 향후 온라인게임분야에서의 데이터기반 보안의 연구 방향을 제시해 보고자 한다.

Approaches to find hidden values using various and enormous amount of data are on the rise. As big data processing becomes easier, companies directly collects data generated from users and analyzes as necessary to produce insights. User-based data are utilized to predict patterns of gameplay, in-game symptom, eventually enhancing gaming. Accordingly, in this study, we tried to analyze the gaming strategy and user activity patterns utilizing Battlegrounds in-game data to detect the in-game hack.

The progress in Information & Communication Technology enables data scientists to analyze big data for identifying peoples' daily lives and tacit preferences. A variety of industries already aware the potential usefulness of analyzing big data. However limited use of big data has been performed in game industry. In this research, we adopt data mining technique to analyze data gathered from a strategic simulation game. Decision Tree, Random Forest, Multi-class SVM, and Linear Regression techniques are used to find the most important variables to users' game levels. We provide practical guides for game design and usability based on the analyzed results.

교육용 소프트웨어 산업이 급속히 발전하면서 온라인 게임을 플랫폼으로 하는 다양한 교육용 게임이 개발되고 있다. 현재 대부분 교육용 게임 시스템은 온라인 게임의 학습도구와 웹을 기반으로 하는 부가적 교육 학습도구로 이중화 되어 개발되고 있다. 하지만 온라인 게임의 학습 데이터 결과와 웹의 학습 데이터 결과가 일치화 되지 않아 학습자에게 올바른 학습 결과를 줄 수 없을 뿐만 아니라 게임 시스템의 학습과정에 따른 레벨 시스템을 적용하기가 어렵다. 본 논문에서는 이러한 비동기적 데이터 처리방식을 온라인 게임 시스템과 웹의 학습과정의 분기 조건에 필요한 학습결과 데이터만을 동기화 처리하는 학습 데이터 동기화 처리 방식을 구현하였다. 이러한 학습결과 데이터 동기화 처리는 위와 같은 문제점으로 다양한 학습 콘텐츠들이 온라인화 하지 못했던 문제점을 해결하고, 향후 통합 교육용 시스템과 다중 교육용 게임 시스템으로 개발 될 때 좀 더 효과적인 학습 시스템으로 개발될 수 있는 학습 데이터 처리 방식이 될 것이다.

With the development in the IT industry and the growth in the game industry, user's game data is recorded in seconds according to various plays and options, and a vast amount of game data can be analyzed based on Bigdata. Combined with business, Bigdata is used to discover new values for profit creation in various fields, but it is utilized in the game industry in insufficient ways. In this study, considering the characteristics of the subdivided lines, we constructed a win-loss prediction model for each line using the game data of League of Legends, and derived the importance of variables. This study can contribute to planning of strategies for general game users to get information about team members in advance and increase the win rate by using the record search sites.

On this paper, suggests a communication structure making possible to fast data send-receive for the gaming process synchronization. For these things, first of all, analyze the data send-receive speed effecting on the online game by the game genre. Moreover, we suggested a proper data communication structure like real-time online action game genre which gaming synchronization effects on the gaming process. Communication structure suggested on this paper is being used with TCP/UDP protocol, and it is applied to the network system and verify improved data send-receive speed. These data send-receive structure can be applied to the various online games.

I designed the game UCI identification metadata to enable the game industry to provide copyright protection of game content, the efficiency of the management and distribution. This was mapped with existing UCI metadata which is composed of 9 elements that are applied to international standards for interoperability. I redefined 3 elements and added 3 more elements for reflecting the characteristics of the game. So it is composed of 12 elements in total. The result is verified by the general user survey and expert interviews. And I will develope the game UCI identification metadata management system with the results of study to be utilized by game agencies.

Methodology of server development is so important for the development of online game because the client where the users play the online game depends on the server. In this research, we have studied data linkage methods of the online game server which permits the server to save and retrieve the user data on the database. The data linkage method of the server is critical to make the users continue their games anywhere online. In this paper, several data linkage methods have been proposed and classified with their definitions. The proposed methods have been evaluated with the experimental data. It will contribute for the developer of online game server to choose a good data linkage method for the features of the game.

We think that it is important to develop the metadata for educational game. Because they are applicable to game contents, separate learning sources and studying components in the game-based LCMS. But markets of eduainment and educational games are newborn field, so systematic development of metadata is not advanced yet. Therefore in this paper, we first established the design process of educational game metadata, and then according to the rule, we suggested this as a prototype. And we defined the extracted data as metadata for educational game through inspection of an expert group. If these metadata prototype are operated by adopting through standardization stage of public institutes, we can provide the convenience of searching, managing and recycling these metadata to learner, instructor and the developing institute. And we can also expect the prevention of overlapping investment.
