Abstract

Methods and apparatus for filtering wagering game content are described herein. In one embodiment, the wagering game system includes a wagering game content filter to receive wagering game content over a communications network and to authenticate the wagering game content. The wagering game system can also include a memory unit to receive the wagering game content after the wagering game content filter has authenticated the wagering game content. The wagering game system can also include a processor to fetch the wagering game content from the memory unit and to conduct a wagering game based on the wagering game content.

7. The wagering game system of claim 1, wherein the wagering game content is selected from the group consisting of audio content, video content, and computer program code.

8. The system of claim 1, wherein the wagering game content filter includes a storage unit to store the wagering game content, the wagering game content filter deleting the non-authenticated content from the storage unit.

9. The system of claim 1, further including a wagering game content server from which the wagering game content filter receives the wagering game content over the communications network.

10. The system of claim 1, further including a persistent storage unit, and wherein the wagering game content filter forwards the authenticated wagering game content to the persistent storage unit.

11. The system of claim 1, wherein the three-way handshake comprises:

transmitting a challenge message from the wagering game content filter to the filter authentication unit;

receiving a digitally signed version of the challenge message from the filter authentication unit;

authenticating the digitally signed version of the challenge message; and

upon authenticating the digitally signed version of the challenge message, indicating to the filter authentication unit that the digitally signed version has been authenticated.

12. The system of claim 1, wherein the filter authentication unit is disposed within a cabinet and the wagering game content filter is disposed outside the cabinet, and wherein the wagering game content filter is to provide filtered wagering game content to a plurality of wagering game machines in the wagering game system, wherein each of the wagering game machines comprise an associated filter authentication unit to authenticate the wagering game content filter and be authenticated by the wagering game content filter prior to providing filtered wagering game content.

13. A non-transitory machine readable medium including instructions, which when executed by a machine, cause the machine to perform operations comprising:

receiving wagering game content over a communications network;

determining, at a wagering game content filter, whether the wagering game content originated from a trusted source and whether the wagering game content has been modified;

authenticating a filter authentication unit using the wagering game content filter, the filter authentication unit being coupled to a wagering game machine, wherein authenticating the filter authentication unit is performed using a three-way handshake between the wagering game content filter and the filter authentication unit;

upon authenticating the filter authentication unit, transmitting wagering game content to the wagering game machine.

14. The non-transitory machine readable medium of claim 13 to cause the machine to further perform operations comprising:

if the wagering game content did not originate from a trusted source or if the wagering game content has been modified, prohibiting transmission of the wagering game content to the memory unit.

15. The non-transitory machine readable medium of claim 13 to cause the machine to further perform operations comprising:

encrypting the wagering game content in a format that can be unencrypted by the wagering game machine.

16. The non-transitory machine readable medium of claim 13, wherein the wagering game content is selected from the group consisting of audio content, video content, and computer program code.

17. The non-transitory machine readable medium of claim 13, wherein the machine-readable medium is disposed within a cabinet of the wagering game machine.

18. The non-transitory machine readable medium of claim 13, wherein the machine-readable medium is disposed outside a cabinet of the wagering game machine.

19. A method comprising:

authenticating a wagering game content filter using a filter authentication unit;

upon authenticating the wagering game content filter;

receiving, in a wagering game machine, wagering game content forwarded from the wagering game content filter, wherein the wagering game content is received over a network;

authenticating the filter authentication unit before forwarding the wagering game content, wherein the filter authentication unit and the wagering game content filter authenticate each other using a three-way handshake; and

forwarding the wagering game content after determining that the wagering game content originated from a trusted source and was not modified; and

conducting a wagering game using the wagering game content.

20. The method of claim 19, wherein the wagering game content includes audio content, video content, or computer program code.

21. The method of claim 19, wherein the wagering game content is received in a memory unit.

22. The method of claim 21, wherein the memory unit and the gaming content filter are contained within a cabinet.
