User identification based on game-play activity patterns
Kuan-Ta Chen, Li-Wen Hong · 2007
Account hijacking is considered one of the most serious security problems in online games. A hijacker normally takes away valuable virtual items from the stolen accounts, and trades those items for real money. Even though account hijacking is not uncommon, there is currently no general solutions to determine whether an account has been hijacked. The game company is not aware of a hijack unless it is reported by the victim. However, it is usually too late---usually a hijacker already took away anything valuable when a user finds that his/her account has been stolen.
