초록
온라인 게임의 인기가 증가하면서 희소성 있는 재화를 현금으로 바꾸는 RMT (Real Money Trade) 유저들이증가하였고 이를 전문적으로 이용하는 게임 내 범죄 집단인 GFG (Gold Farming Group)이 나타났다. GFG는게임재화를 수집하기 위해서 다수의 봇 계정이 필요한데, 이를 위해 명의 도용, 개인정보 유출 문제를 발생시키게된다. 또한 현금거래를 유발시켜 게임 내 경제의 형평성을 파괴하고, 계정 도용, 아이템 탈취를 유발 시킨다. 따라서GFG를 제거 및 차단하는 일은 사회적, 게임 내 관점에서 중요한 문제이다. 본 논문은 기존의 판매자 관점의 탐지가 아닌 수요공급의 원칙에 따라 현금거래 구매자를 탐지하는 근본적인 방안을 제시하였다. 실제 게임 데이터를 분석하여 두 가지의 RMT 형태를 발견하였고, 구매자 탐지의 재현율이 98% 이상을 보일 수 있었다.
Abstract
As the rise in popularity of online games, the users start exchanging rare items for real money. As RMT (Real Money Trade) is prevalent, GFG (Gold Farming Group) who abuse RMT shows up. GFG causes social problems such as identity theft, privacy leaks. Because they needs many bot characters to gather game items. In addition, GFG induce RMT that makes in-game problems such as a destroying game economy, account hacking. Therefore, It is very important work to collapse GFG at the perspective of social and in-game. In this paper, we proposed a fundamental method for detecting RMT buyers for the collapse of GFG at the perspective of buyer by Law of Demand and Supply. We found two type of RMT by analyzing actual game data and detected RMT buyers with high recall ratio of 98% by ruled-based detection.
