Abstract

Various techniques are disclosed for authenticating a first gaming application adapted for deployment at a first gaming machine that is operable to receive a wager on a game of chance. A first gaming application signature is accessed. In at least one embodiment, the first gaming application signature is associated with a first portion of a first plurality of gaming objects that are associated with the first gaming application. A first certified gaming signature associated with the first gaming application may also be accessed. Authentication of the first gaming application may be performed. In at least one embodiment, the first gaming application may be authenticated, for example, by comparing at least one gaming application signature with at least one certified gaming signature. If it is determined that the first gaming application is not authentic, the first gaming application signature may be analyzed to identify at least one invalid gaming object.

wherein the generating of the object signatures comprises at least one of;

generating a checksum from a corresponding one of the first plurality of gaming objects, applying a hashing function to a portion of a corresponding one of the first plurality of gaming objects, generating an audio file signature, generating a video file signature, and extracting a digital water mark.

4. The method of claim 1 further comprising:

generating an object signature for each of the first portion of the first plurality of gaming objects; and

combining the object signatures to generate the first gaming application signature;

wherein the combining of the object signatures comprises at least one of;

combining the object signatures using at least one logic function, applying a hashing function to the object signatures, and generating a checksum from the object signatures.

5. The method of claim 1 further comprising:

analyzing individual object signatures associated with the first portion of the first plurality of gaming objects to identify at least one invalid gaming object.

6. The method of claim 1 wherein the certified gaming signature includes a plurality of certified gaming objects, the method further comprising:

generating a separate object signature for selected objects of the first portion of the first plurality of gaming objects; and

comparing a first certified gaming object to a corresponding object signature of the first portion of the first plurality of gaming objects in order to identify at least one invalid gaming object.

7. The method of claim 1 further comprising:

detecting a noncompliance condition relating to the authentication of the first gaming application; and

analyzing, in response to detection of the noncompliance condition, the first gaming application signature to identify at least one invalid gaming object associated with the noncompliance condition.

8. The method of claim 1:

wherein the first gaming application is deployed at the first gaming machine; and

wherein the first portion of the first plurality of gaming objects are deployed at the first gaming machine.

9. The method of claim 1 further comprising wherein the first portion of the first plurality of gaming objects correspond to gaming objects deployed at the first gaming machine.

10. The method of claim 1 wherein the first plurality of gaming objects are stored in at least one network node of a network, and wherein the first portion of the first plurality of gaming objects are retrieved from the at least one network node via the network.

11. The method of claim 1 wherein the first plurality of gaming objects are stored on a gaming application server.

12. The method of claim 1 wherein the first gaming application signature comprises an original signature, the method further comprising:

storing the original signature for authentication of subsequently generated signatures corresponding to deployed gaming applications.

13. The method of claim 1 wherein the first gaming application signature corresponds to a deployed gaming application, the method further comprising:

comparing the first gaming application signature to a previously stored original signature to authenticate the first gaming application.

14. The method of claim 13 further comprising:

generating an object signature for each of the first portion of the first plurality of gaming objects; and

comparing at least one of the object signatures to a corresponding object signature associated with the previously stored original signature where the first gaming application is determined to be not authentic.

15. The method of claim 1 wherein the first plurality of gaming objects includes one or more objects selected from a group including:

a core gaming object, an audio object, a video object, a graphics object, a pay table object, and a non-core gaming object.

16. The method of claim 1:

wherein the first plurality of gaming objects are stored in at least one of;

a gaming application server and a gaming machine in a network; and

wherein the first portion of the first plurality of gaming objects are retrieved via one of;

the gaming application server and the gaming machine in the network.

17. A system for authenticating a first gaming application adapted for deployment at a first gaming machine, the first gaming machine being operable to receive a wager on a game of chance, the system comprising:

at least one processor;

at least one interface operable to provide a communication link to at least one other network device in the data network; and
