Abstract
Provided are a method and system for detecting a bot in a Massive Multiplayer Online Role Playing Game (MMORPG) online and in real time. By analyzing a communication pattern between a client and a server, the bot is detected based on parameters such as data length, inter-arrival time and data length auto correlation. Tests using respective parameters are combined to construct a global decision scheme, and thus more accurate detection results can be obtained. An integrated anti-bot defense system can be built by combining other tests such as a Turing test.
Claims2
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 (itthr1) 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 (itthr2) 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 (itthr1) is less than a third threshold (itrt1), or a ratio of the number of packets having the inter-arrival time over the second threshold (itthr2) and the number of packets having the inter-arrival time over the first threshold (itthr1) is more than a fourth threshold (itrt2).
A method for detecting a bot in a Massive Multiplayer Online Role Playing Game (MMORPG), the method comprising:
- counting the number of packets having a data length over a first threshold (dlthr1) among consecutive packets inputted from a user within a window having a predetermined size;
- counting the number of packets having the data length over a second threshold (dlthr2) among the consecutive packets;
- and
- determining the user as a bot when the number of packets having the data length over the first threshold (dlthr1) is less than a third threshold (dlrt1), and the number of packets having the data length over the second threshold (dlthr2) is less than a fourth threshold (dlrt2).
