Korean Game industry, especially MMORPG(Massively Multiplayer Online Game) has been rapidly expanding in these days. But As game industry is growing, lots of online game security incidents have also been increasing and getting prevailing. One of the most critical security incidents is 'Game Bots', which are programs to play MMORPG instead of human players. If player let the game bots play for them, they can get a lot of benefic game elements (experience points, items, etc.) without any effort, and it is considered unfair to other players. Plenty of game companies try to prevent bots, but it does not work well. In this paper, we propose a behavior pattern model for detecting bots. We analyzed behaviors of human players as well as bots and identified six game features to build the model to differentiate game bots from human players. Based on these features, we made a Naive Bayesian classifier to reasoning the game bot or not. To evaluated our method, we used 10 game bot data and 6 human Player data. As a result, we classify Game bot and human player with 88% accuracy.

This paper proposes and tests a theoretical model of the relational link between a novel form of customer-perceived fairness for a reward design (distributive peer justice climate) and C2C helping intention via community identification and online C2C interaction (friend-, neighboring customer-, audience-interaction) qualities in a collective consumption context (MMORPG). To test hypotheses, we amassed survey data within a collective consumption context (massively multiplayer online role-playing games, MMORPGs). We used structural equation modeling in analyzing the survey data. The results reveal that user-perceived distributive peer justice climate for a reward design enhances their C2C helping intention via community identification and C2C interactions in MMORPG contexts. Collective consumption-type service managers should focus on promoting the user-perceived distributive peer justice climate for their reward system to enhance users' present C2C co-creation experience (community identification, C2C interaction) and future C2C co-creation behavior (helping intention). By adopting an intra-unit level distributive justice concept (customer-perceived distributive peer justice climate) to a reward design in a collective consumption context (MMORPGs), this study informed collective consumption-type service managers of the importance of its management.

User enjoyment is a key factor to understand online and mobile game users' behaviors. This study aims to understand the differences between mobile and online games, and the differences between Korean and Chinese game users in terms of the perceived importance of user enjoyment elements. To use AHP (Analytic Hierarchical Process), we decompose user enjoyment into sub-elements; sensory enjoyment, content enjoyment, enjoyment of the achievement, and enjoyment of interaction. Though the empirical study and independent t-test, we can find that there are the differences in the perceived importance of user enjoyment elements between Korean and Chinese game players, and between mobile and online games. Chinese users more stress on enjoyment of interaction and Korean users more emphasize on enjoyment of the achievement.

최근 온라인게임, e-Book, 모바일콘텐츠, 포털 등 IT 기반의 새로운 서비스 산업으로서 디지털콘텐츠 산업이 급성장하고 있다. 또한, 과거 엔터테인먼트 위주의 콘텐츠산업이 미래에는 제조, 서비스를 포함한 전 산업영역에 체화융합되어 확산되고, CT 및 IT 기반의 새로운 콘텐츠 산업이 급성장할 것으로 전망되는 등 융합형 콘텐츠에 대한 관심이 증대되고 있다. 정부에서도 신성장동력으로서의 융합형 콘텐츠 산업에 주목하여, 관련 산업을 발굴육성하는데 정책적 관심을 기울이고 있다. 기존의 콘텐츠 분류체계는 영화, 음악, 방송 등 장르 중심적이어서 관련 기술의 발전 및 융합현상을 제대로 반영하지 못하는 한계점을 가지고 있다. 따라서 미래 정책추진의 기반(base)로서 효과적으로 활용되고, 콘텐츠 분야의 외연확장을 포괄하는 새로운 분류체계(taxonomy)의 정립이 요구되는 상황이다. 이에 본 고에서는 미래 정책추진 및 산업활성화에 초점을 맞추어 기존 분류체계의 한계점을 극복하는 차세대 융합형 콘텐츠 산업에 대한 새로운 분류체계를 제시하고자 한다.

이동통신 시장에서 SKT의 시장 점유율이 점차 높아지면서 KTF와 LGT의 가입자 이탈 막기에 비상이 걸렸다.지난 9월말 기준 이동전화 가입자 현황을 살펴보면 SKT는 전달에 비해 6만2,868명이 늘어난 데 반해 KTF와 LGT는 각각 2,053명과 7,541명이 줄어든 것으로 나타났다. 이 같은 현상은 올해 내내 이어지고 있는 상황으로 LGT의 경우 지난 3월 이후 약 11만6,000여명의 가입자가 이탈한 것으로 나타났다.이에 따라 KTF와 LGT는 SKT의 독주체제를 막기 위해 모바일 뱅킹 사업에 대한 전략적 제휴를 체결하는 등 방안 마련에 부심하고 있는 것으로 알려 졌다. KTF의 한 관계자는“이동통신시장의 특성상 지배적 사업자가 갖는 이점으로 인해 이 같은 현상이 나타나고 있지만 한발 앞선 모바일 콘텐츠 서비스 등으로 가입자 기반을 점차 늘려 나갈 계획”이라고 밝혔다.한편, 초고속인터넷 서비스 가입자수의 경우 지난달에 약 5만여명이 늘어나 증가세가 계속되고 있는 것으로 나타났다.

The authors map some of the current Business Models in the Massively Multiplayer Online Player scenario. These maps represent Value Creation Systems by resorting to Value Net constructs and notations, and are offered here as a proof of concept and utility. The authors claim that these mappings can enable readers, managers and IT experts, to build new insights onto such Business Models and develop requirements for Information System infrastructure. When approaching the Value Creation System as a Value Net the goal is to think outside the conceptual box of Value Chains and understand how the different activities interact, by exposing the multiplicity of value types and flows. In doing this study the authors are attempting to synthesize a new Business Model proposal that could underlie the development of an infrastructure for the collaborative creation, distribution and exploration of online massively multiplayer games, beyond the traditional producer-consumer roles.

Although interest in the metaverse increases due to the pandemic, the understanding of the metaverse interest factor, which is an essential element for the sustainability of any metaverse platform, is lacking. This study aims to reveal the interest factors of metaverse services by analyzing user community discourse. We collected user community discourses from and applied LDA to extract topics. Further, we categorize the factors into growth and verifiable indicators, various levels of interaction, self-expression and freedom, and connection with the real world. The content planning direction of the game-based metaverse of utilization was derived. This study is meaningful in that it analyzes the interest factors of the metaverse based on the empirical evidence of user discourse data.

As digital content services, especially OTT(over-the-top) video services, diffuse rapidly, so do smartTVs. Based on the indirect network effect theory and the complementarity theory, this study explores the relationship between digital content services and smartTV. Using the Media panel dataset, this study analyzes how the usage of digital content service (OTT usage, OTT usage volume, the usage of various OTT service types, and online game/music/education/news service) affects smartTV usage. This study shows that OTT usage and its usage volume is positively associated with smartTV usage, and that the usage of various OTT service types is positively associated with smartTV usage compared with non-OTT users. As for online content services, the usage of online education service is positively associated with smartTV usage while the usage of online news service is associated negatively. These results support the indirect network effect theory and the complementarity theory.

Recently, most of information services are provided by the computer network, since the technology of computer communication is developing rapidly, and the worth of information over the network is also increasing with expensive cost. But various attacks to quietly intercept the informations is invoked with the technology of communication developed, and then most of the financial agency currently have used OTP, which is generated by a token at a number whenever a user authenticates to a server, rather than general static password for some services. A 2-Factor OTP generating method using the OTP token is mostly used by the financial agency. However, the method is vulnerable to real attacks and therefore the OTP token could be robbed and disappeared. In this paper, we propose a 3-Factor OTP way using HMAC to conquer the problems and analyze the security of the proposed scheme.
