The embodiments described herein relate generally to electronic gaming machines and, more particularly, to systems and methods for use in authenticating gaming machine content.
At least some gaming machines include gaming packages that include a plurality of files used to present one or more games to a player. Each gaming package typically contains the files associated with a specific game. A processor displays aspects of the game to the player using graphic files and may also cause one or more sounds to be generated from sound files stored within the gaming package. The processor also uses data files within a memory area of the gaming machine to account for or to record bonus awards, credits or payments paid by the player, the player's play history, and/or other aspects of the game.
To prevent unauthorized modification of the game files, at least some gaming machines may execute a verification process on the gaming packages. For example, at least some gaming machines may store a file signature or other verification data for each gaming package, and may use the stored verification data to determine if the files have changed during a boot process of the gaming machine and/or after the gaming package has been downloaded into the gaming machine. Such a verification process may be time-consuming for gaming machines that have a large number of gaming packages.
In one aspect, a gaming machine may include a memory area including at least one bootup memory device, and at least one data storage device including at least one operating system and a plurality of gaming packages. The gaming machine also may include a display device configured that may display at least one game selected from the plurality of gaming packages to a player, and a processor coupled to the memory area and to the display device. The processor may authenticate the at least one bootup memory device, and may authenticate the at least one operating system. The processor may also be configured to determine an authentication sequence for the plurality of gaming packages, and authenticate the plurality of gaming packages in a sequence different from the determined authentication sequence.
In another aspect, a method of authenticating gaming machine content may include authenticating at least one bootup memory device of the gaming machine, may authenticate at least one operating system of the gaming machine, may receive at least one of a local user input to the gaming machine and an input to the gaming machine from a remote device, and may authenticate a plurality of gaming packages after receiving the at least one of a local user input and an input from a remote device.
Exemplary embodiments of apparatus, methods, and computer-readable storage media having computer-executable components for use in authenticating gaming machine content, such as gaming packages, operating systems, and initialization software of bootup devices, are described herein. The embodiments described herein may enhance the security of gaming machines and may be implemented to determine whether gaming packages and/or operating systems installed within gaming machines may be authenticated or should be trusted. Moreover, the embodiments described herein may enable gaming machines to be accessible to users while gaming packages may be authenticated.
As used herein, an element or step recited in the singular and proceeded with the word “a” or “an” should be understood as not excluding plural elements or steps, unless such exclusion is explicitly recited. Furthermore, references to “one embodiment” of the present disclosure are not intended to be interpreted as excluding the existence of additional embodiments that also incorporate the recited features.

Moreover, processor 104 may authenticate at least a portion of data storage device 146 (i.e., the instructions and/or data within a portion of data storage device 146), such as the instructions and/or data that may be required to boot or execute primary operating system 402 that may be stored within data storage device 146.
Primary operating system 402, in the exemplary embodiment, may execute authentication module 412 to authenticate gaming operating system 404 and gaming packages 406. Authentication module 412 may execute gaming operating system 404 once system 404 has been authenticated. Moreover, authentication module 412 may authenticate gaming packages 406 while gaming operating system 404 may execute (e.g., in the background and/or in parallel with gaming operating system 404). In the exemplary embodiment, gaming operating system 404 may enable and/or may receive local player input (and/or input from a remote device) and/or interaction with gaming machine 100 while gaming packages 406 may be authenticated. More specifically, input from a player or a remote device may be received and may be acted upon concurrently with the authentication of gaming packages 406. If input from the player or remote device is not received, authentication module 412 may authenticate gaming packages 406 according to a default, or predetermined sequence. In one embodiment, the default authentication sequence may be downloaded to gaming machine 100 by a remote server or another device such that gaming packages 406 may be authenticated according to the downloaded sequence upon the next bootup of gaming machine 100.
Moreover, in the exemplary embodiment, authentication module 412 may authenticate gaming packages 406 in a selectable, adjustable, and/or dynamic sequence such that authentication module 412 may depart from the default authentication sequence to authenticate gaming packages 406 in a sequence different from the default sequence. In one embodiment, gaming packages 406 may be authenticated in order of popularity. Accordingly, the most popular game may be authenticated first, the second-most popular game may be authenticated next, and the like. In one embodiment, gaming operating system 404 may receive data from a remote device or server, such as player tracking server 206 (shown in
In another embodiment, authentication module 412 may authenticate gaming package 406 and may include the game that was last played by the player or the last game that was played on gaming machine 100 by any player. In other embodiments, authentication module 412 may authenticate gaming packages 406 according to player preferences (stored within gaming machine 100 and/or received from player tracking server 206 or another remote server or device), according to the game or gaming package 406 most recently installed within gaming machine 100, and/or according to any other predetermined, configurable, or selectable criteria.
In the exemplary embodiment, the authentication of gaming packages 406 may be player selectable and/or player overridable. Additionally or alternatively, the authentication of gaming packages 406 may be selectable and/or overridable by a remote device, such as a server. For example, authentication module 412 may begin authenticating a first gaming package 406 as part of a predetermined authentication sequence, and a player may input a selection to play an unauthenticated game, and/or an input from a remote device may be received concurrently with the authentication of first gaming package 406. In such an embodiment, the unauthenticated game may be indicated as unavailable, for example, by displaying the title of the game with a reduced opacity and/or using a reduced color palette (e.g., in a “grayed out” manner), and/or a message may be displayed to the player indicating that the game will begin after a delay. Authentication module 412 may stop authenticating the first gaming package 406 and may depart from the predetermined authentication sequence and may authenticate the selected gaming package 406. After the selected gaming package 406 has been authenticated, authentication module 412 may resume the prior authentication sequence by authenticating first gaming package 406.
In one embodiment, authentication module 412 may prioritize the selected gaming package 406 above the next identified gaming package in the sequence (i.e., above a second gaming package 406). Accordingly, the selected gaming package 406 may be authenticated after (or concurrently or in parallel with) first gaming package 406 and before second gaming package 406. After the selected gaming package 406 has been authenticated, authentication module 412 may resume authenticating gaming packages 406 (including second gaming package 406) according to the predetermined authentication sequence.
Moreover, in the exemplary embodiment, a plurality of gaming packages 406 may be authenticated in parallel. For example, processor 104 may include a plurality of execution units, or cores, and/or may be multi-threaded such that a plurality of instructions may be executed concurrently. In such an example, processor 104 may authenticate (using authentication module 412) a first gaming package 406 using a first core or thread, and may authenticate additional gaming packages 406 using additional cores or threads. Moreover, in the exemplary embodiment, authentication module 412 may authenticate executable files and non-executable files, such as graphic files, sound files, data files, and/or any other files within gaming packages 406.
In the exemplary embodiment, authentication module 412 may authenticate each certificate file 408 and each gaming package 406 by accessing certificate file 408 associated with gaming package 406. Authentication module 412 may decrypt file signature 418 to obtain the stored hash value of certificate file 408. Authentication module may calculate the hash value of certificate file 408 and may compare the calculated hash value to the stored hash value. If the calculated hash value equals the stored hash value, authentication module 412 may determine that certificate file 408 may be intact and unmodified (i.e., that certificate file 408 is “trusted”). If the calculated hash value does not equal the stored hash value, authentication module 412 may stop authenticating gaming package 406 and may generate an error message or indicator to an administrator, remote server, or another device or individual.
If authentication module 412 may determine that certificate file 408 may be authenticated or trusted, authentication module 412 may receive file data section 416 from certificate file 408. Authentication module 412 may calculate a hash value of the files identified in file data section 416 and compares the calculated hash value to the stored hash value of the files. If the calculated hash value equals the stored hash value of the files, authentication module 412 may determine that gaming package 406 may be unmodified or trusted. Authentication module 412 may then enable the authenticated gaming package 406 to be loaded and/or accessed by gaming operating system 404 and the player, and may identify gaming package 406 as being authenticated within the list stored in database 410. Moreover, authentication module 412 may continue authenticating other gaming package 406 that may be listed in database 410 as being unauthenticated. However, if the calculated hash value does not equal the stored hash value of the files, authentication module 412 may stop authenticating gaming package 406 and may generate an error message or indicator to an administrator, remote server, or another device or individual.
Accordingly, as described herein, gaming machine 100 and authentication system 300 may provide increased security during a bootup of machine 100 as compared to prior art gaming machines. Moreover, gaming machine 100 and authentication system 100 may increase player satisfaction by enabling gaming machine 100 to be accessible while gaming packages 406 may be in the process of being authenticated. If a player wants to play a game that has not yet been authenticated, authentication module 412 may prioritize the gaming package including the game above other gaming packages 406 in the authentication sequence. As such, authentication system 300 may enable gaming machine 100 to be more accessible to players while retaining and/or improving the security of gaming packages 406 and gaming machine 100.
In the exemplary embodiment, method 500 may include determining 502 a physical security of gaming machine 100. For example, physical security device 302 (shown in
After processor 104 may have authenticated 504 first bootup memory device 142, processor 104 and/or first bootup memory device 142 may authenticate 506 second bootup memory device 144 and instructions from second bootup memory device 144 may be executed. When processor 104 and/or first bootup memory device 142 may have authenticated 506 second bootup memory device 144, second bootup memory device 144 may authenticate 508 a first, or primary operating system 402 (shown in

In one embodiment, the computer-readable storage media may also include a gaming operating system, wherein the authentication module causes the at least one processor to authenticate the gaming operating system. In addition, the computer-readable storage media may include a plurality of certificate files associated with the plurality of gaming packages, wherein the authentication module causes the at least one processor to use data included within the plurality of certificate files to authenticate the plurality of gaming packages. More specifically, the authentication module may cause the at least one processor to authenticate each certificate file associated with each gaming package, and authenticate each gaming package if the associated certificate file is authenticated.
In another embodiment, the computer-readable storage media may include a first certificate file associated with a first gaming package of the plurality of gaming packages. The first certificate file may include a file signature section including an encrypted hash value of the first certificate file. The authentication module may cause the at least one processor to decrypt the encrypted hash value to obtain an unencrypted hash value of the first certificate file, calculate a hash value of the first certificate file, and compare the calculated hash value of the first certificate file with the unencrypted hash value of the first certificate file for use in authenticating the first certificate file.
Moreover, the first certificate file may include a file data section including a hash value of the first gaming package. The authentication module may cause the at least one processor to calculate a hash value of the first gaming package and compare the calculated hash value to the hash value of the file data section for use in authenticating the first gaming package. The file data section may include a list of files within the first gaming package such that the authentication module causes the at least one processor to calculate a hash value of the files listed within the file data section and compare the calculated hash value to the hash value of the file data section for use in authenticating the first gaming package.
In another embodiment, an authentication system for use with a gaming machine may include at least one bootup memory device and a data storage device including at least one operating system and a plurality of gaming packages. The authentication system may also include a processor coupled to the at least one bootup memory device and the data storage device. The processor may be configured to authenticate the at least one bootup memory device, authenticate the at least one operating system, receive at least one of a local user input and an input from a remote device, and authenticate the plurality of gaming packages after receiving the at least one of the local user input and the input from the remote device.
The authentication may also include a physical security device configured to determine a physical security of the gaming machine. In addition, the at least one operating system may include a primary operating system and a gaming operating system. The at least one operating system may also include an authentication module such that the processor may be configured to authenticate the plurality of gaming packages by executing the authentication module and authenticating the plurality of gaming packages using the authentication module.
In one embodiment, the processor may be configured to authenticate the plurality of gaming packages by determining an authentication sequence for the plurality of gaming packages and departing from the determined authentication sequence in response to an input received by the gaming machine. In another embodiment, the processor may be configured to authenticate the plurality of gaming packages by authenticating a first gaming package of the plurality of gaming packages according to a determined authentication sequence. The determined authentication sequence may identify a second gaming package of the plurality of gaming packages to be authenticated after the first gaming package has been authenticated. The processor may be further configured to authenticate the plurality of gaming packages by receiving at least one of a local user input and an input from a remote device, and prioritizing an authentication of a third gaming package of the plurality of gaming packages over an authentication of the second gaming package. After the third gaming package has been authenticated, the processor may be further configured to return to the predetermined authentication sequence.
In another embodiment, the processor may be configured to authenticate the plurality of gaming packages in parallel. In yet another embodiment, the processor may be configured to authenticate the plurality of gaming packages concurrently with the receipt of at least one of the local user input and the input from the remote device. In a still further embodiment, a first gaming package of the plurality of gaming packages may include at least one non-executable file such that the processor may be configured to authenticate the at least one non-executable file.
The above-described embodiments may provide benefits to casinos, gaming machine manufacturers, and players alike. For example, using the present disclosure may enable casinos to gain increased security from the authentication process, and may increase player satisfaction by enabling gaming machines to be accessible while gaming packages are in the process of being authenticated.
