Abstract
Description
- This application claims the benefit of U.S. Provisional Application Ser. No. 60/565,791 filed Apr. 26, 2004, which is incorporated herein by reference.
- A portion of the disclosure of this patent document contains material to which the claim of copyright protection is made. The copyright owner has no objection to the facsimile reproduction by any person of the patent document or the patent disclosure, as it appears in the U.S. Patent and Trademark Office file or records, but reserves all other rights whatsoever.
- This invention relates generally to the field of gaming systems and more particularly to secure gaming system communication techniques.
- Casino gaming machines (e.g., video slots, video poker, video blackjack, video keno, video bingo, video pachinko, and video lottery) are often configured to operate as part of a host-based gaming network. Host-based gaming networks typically include a number of gaming machines, where each gaming machine is communicatively coupled via a single dedicated data channel (i.e. a non-public data channel) to one or more gaming hosts. In such a configuration, the gaming hosts collect various types of gaming data, such as betting information, payout information, banking information, etc. over the single data channel. One disadvantage of using a single data channel to transmit information between gaming machines and a gaming host is that a single data channel may be difficult to secure. An infiltrator could access to all communications between the gaming machine and the gaming host by breaching the single data channel. Another disadvantage of the single data channel is a lack of bandwidth. Currently, most of the dedicated gaming data channel networks are bandwidth-limited RS232 networks, which operate at 19.2 kbps to 38.4 kbps.
- A method and system for using multi-channel communications to enhance security is described herein. In one embodiment, the method comprises receiving in a first gaming device a set of gaming data stream portions over a plurality of data channels, wherein the gaming data stream portions are received from a second gaming device. The method further comprises combining ones of the set of gaming data stream portions into a gaming data stream.
- In one embodiment, the system includes a first gaming device for performing a number of operations. The operations include disassembling a gaming data stream into gaming data stream portions and transmitting the gaming data stream portions. The system also includes a second gaming device for performing the following operations: receiving the gaming data stream portions and assembling the gaming data stream portions into the gaming data stream. The system also includes a plurality of data channels for transmitting gaming data stream portions from the first gaming device to the second gaming device.
