Claim:
A method for detecting a bot in a Massive Multiplayer Online Role Playing Game (MMORPG), the method comprising: counting the number of packets having an inter-arrival time over a first threshold (itthr 1 ) among consecutive packets inputted from a user within a window having a predetermined size; counting the number of packets having the inter-arrival time over a second threshold (itthr 2 ) among the consecutive packets; and determining the user as a bot when the number of packets having the inter-arrival time over the first threshold (itthr 1 ) is less than a third threshold (itrt 1 ), or a ratio of the number of packets having the inter-arrival time over the second threshold (itthr 2 ) and the number of packets having the inter-arrival time over the first threshold (itthr 1 ) is more than a fourth threshold (itrt 2 ).
