TLDR
This paper proposes a new biometric for human identification based on users' game-play activities, and proposes the RET scheme, which is based on the KullbackLeibler divergence between idle time distributions, for user identification.Abstract:
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 stolenIn this paper, we propose a new biometric for human identification based on users' game-play activities Our main summary are two-fold: 1) we show that the idle time distribution is a representative feature of game players; 2) we propose the RET scheme, which is based on the KullbackLeibler divergence between idle time distributions, for user identification Our evaluations shows that the RET scheme achieves higher than 90% accuracy with a 20-minute detection time given a 200-minute history sizeread more

A new design for a Turing Test for Bots
TL;DR: A new design is described for a game bot programming competition, the BotPrize, which will make it simpler to run, and, it is hoped, open up new opportunities for innovative use of the testing platform.

TL;DR: The information deviation between any two finite measures cannot be increased by any statistical operations (Markov morphisms) and is invarient if and only if the morphism is sufficient for these two measures as mentioned in this paper.
