Abstract

A system and method for actively validating a network device is provided. Nodes in a network game community are prompted to engage in interrogation and response to facilitate the identification of nodes operating with hacked, modified and non-typical game configurations. In one embodiment, a query is presented to a user'"'"'s machine which triggers a response, and where the response indicates whether certain data at the user is valid and wherein invalid data is suggestive of illegal community behavior. Functions are triggered and data is queried to determine whether the state of game environment is operating according to known metrics or constraints. Various queries to test user integrity include memory peeks, confirmation of location of functions in memory, memory hashing, profiling of threads operating on the user machine, and combinations thereof. Queries may be actively initiated by a server, peer, peer group or combinations thereof and may be scheduled on a routine basis, triggered in response to passive listening, and via collaborating users who suspect cheat activity.

Claims

1. A method for validating network devices in a gaming network, comprising:

sending at least one query to at least one of the network devices, the at least one of the network devices configured for play of a network game;

receiving a response to the at least one query;

determining whether the at least one of the network devices is valid based on the response to the at least one query

designating the at least one of the network devices as validated based on the response to the at least one query; and

sending fewer queries to the at least one validated device than to a network device that has not been validated.

2. The method of claim 1, further comprising determining whether the at least one of the network devices violates rules associated with the network game.

3. The method of claim 2, further comprising resolving a violation of the rule associated with the network game.

4. The method of claim 1, further comprising allowing the at least one of the network devices to continue playing the network game in the gaming network based on the response to the at least one query.

5. A system for validating computing devices in a network game environment comprising:

a computing device configured to monitor one or more computing devices playing a game in a network game environment;

a query engine in communication with the monitoring computing device, the query engine configured to pose at least one query to the one or more computing devices play the game and to receive a response to the at least one query;

an analysis engine in communication with the query engine, the analysis engine configured to determine whether the one or more computing devices are valid based on the response to the at least one query; and

a storage medium configured to store an indication that the one or more computing devices are validated based on the response to the at least one query, wherein the query engine is further configured to send fewer queries to a validated computing device than to a computing device that has not been validated.

6. The system of claim 5, wherein the monitoring computing device comprises a server.

7. The system of claim 5, wherein the one or more computing devices playing a game are associated with one or more users.

8. The system of claim 5, wherein the monitoring computing device is further configured to allow the one or more computing devices to continue playing the network game based on the response to the at least one query.

9. A computer readable medium having embodied thereon a program, the program being executable by a processor for performing a method validating network game users, the method comprising:

monitoring one or more users playing a game in a network game environment;

sending at least one query to the one or more users;

receiving a response to the at least one query;

determining whether the one or more users are valid based on the response to the at least one query;

recording the one or more users as validated based on the response to the at least one query; and

sending fewer queries to a validated user than to a user that has not been validated.

10. The computer readable medium of claim 9, further comprising determining whether the one or more users violate rules associated with the game.

11. The computer readable medium of claim 10, further comprising resolving the violation.

12. The computer readable medium of claim 9, further comprising allowing the one or more users to continue playing the network game based on the response to the at least one query.
