The currency-value converter according to the present invention transmits amount-of-converted-currency data indicating the amount of basic currency identified based on the type of this currency, the amount of the currency and the exchange rate, to a controller installed in a gaming machine, when the type of currency accepted through a currency validator is not the basic currency. The exchange rate is a rate in which a correspondence relationship between an amount of the basic currency and an amount of another type of currency other than the basic currency is set for each type of currency other than the basic currency. Then, a game is played at the gaming machine based on the transmitted amount-of-converted currency.

The system, method, and computer program product described herein provides a built-in feedback mechanism for a blockchain to sanction validator nodes that consistently “vote” in a manner that does not match the ultimate consensus.

An integrity verifier and validator is provided in which an initial anti-virus scan is performed against an entire file system to verify the integrity of the file system and create a corresponding file system level integrity verification database of known scanned regions of the file system. The database contains a copy of the file system's partition table referencing the range of occupied inodes and directory blocks. When new or updated content is written to the file system the integrity of the corresponding occupied inodes and directory blocks is no longer assured, and the integrity verifier flags them on the database for rescanning. Subsequent attempts to rescan any portion of the file system triggers the integrity validator to scan the database to validate whether that portion of the file system falls within any of the occupied inodes or directory blocks that have been flagged for rescanning. If they are not flagged, then rescanning of that portion of the file system is unnecessary as the integrity of at least that portion is assured. However, if they are flagged, then the anti-virus software rescans that portion of the file system for the presence of viruses.

This invention provides automated systems and methods for configuring and reconfiguring gaming machines and games playable on a gaming machine. The automated systems and methods employ a complementary gaming machine configuration device, such as a paper-based ticket, and interface operably associated with a gaming machine, such as a note acceptor or bill validator that receives and reads the paper-based ticket. The gaming machine configuration device stores game parameter configuration information in the form of configuration indicia. The indicia may contain the content required to effect configuration directly or may do so indirectly by containing a reference to a location where a set of configuration parameters have been stored. This location may reside within the gaming machine or external to it, but accessible via. a communications link. The interface reads the indicia from the configuration device, and provides a signal to a processor responsible for managing the gaming machine. The processor has access to software or memory that stores associations between the configuration indicia and configuration and reconfiguration commands for the parameters. The processor and software are then designed or configured to convert the signal provided by the interface to commands that act on appropriate mechanisms of the gaming machine to configure or reconfigure the games and/or gaming machine components responsible for expression of the affected game parameters.

The invention is a method and system for managing admission to an attraction. In one or more embodiments, the system comprises a first queue by which customers may access the attraction by waiting in line and a second queue by which customers may access the attraction in a manner which avoids the first queue. The system includes a first validator for validating an entitlement of a customer to receive an assigned time in the future for accessing the attraction via the second queue, a media distributor for distributing a media to an entitled customer, the media including the assigned time at which the entitled customer is entitled to access the attraction in the future, and a second validator for validating the entitled customer access to the attraction at the time provided on the media. In accordance with a method of the invention, a customer may access an attraction in a manner which avoids standing in a first waiting line by verifying entitlement to utilize a second queue, obtaining a pass entitling the customer to access the attraction at a future time, and returning to the attraction at the future time and gaining access with the pass. In this method, the customer may leave the vicinity of the attraction between when the pass is issued and the future time at which the customer is entitled to access to the attraction.

A disclosed gaming machine has a plurality of “gaming peripherals,” each communicating with a master gaming controller via a standard peripheral interface such as the USB (Universal Serial Bus). Further, the gaming peripherals employ a standard peripheral controller and one or more specialized “peripheral devices” (e.g., the actual lights, bill validators, ticket printers, etc. that perform the specific functions of the gaming peripherals). Much of the hardware associated with the peripheral controller is identical from one gaming peripheral to the next. Only a portion of the peripheral controller hardware is specific to the different types of gaming peripherals.

A network with authentication implemented using a client health enforcement framework. The framework is adapted to receive plug-ins on clients that generate health information. Corresponding plug-ins on a server validate that health information. Based on the results of validation, the server may instruct the client to remediate or may authorize an underlying access enforcement mechanism to allow access. A client plug-in that generates authentication information formatted as a statement of health may be incorporated into such a framework. Similarly, on the server, a validator to determine, based on the authentication information, whether the client should be granted network access can be incorporated into the framework. Authentication can be simply applied or modified by changing the plug-ins, while relying on the framework to interface with an enforcement mechanism. Functions of the health enforcement framework can be leveraged to provide authentication-based functionality, such as revoking authorized access after a period of user inactivity or in response to a user command.

A method and system is provided to provide single sign on (SSO) functionality in a network that avoids storing a user's credentials in persistent storage. A session may be initiated with a portal which sends a session ID derivative as a credential string instead of a user's password to a target application. When the target application attempts to authenticate the user, by sending a request to a LDAP directory, the request is intercepted by a LDAP proxy that instead validates the UserID with the LDAP directory and the password is validated by a credential validator component which verifies with the portal that the credential string presented as the user password has been produced from the active session ID. In an embodiment, the credential string validator validates each short-living credential only once and upon detecting a second validation request for the same string, initiates a security breech process. A target application proxy may also be employed to terminate all sessions with the UserID when duplicate session requests occur.

A computer-implemented method and system for the validation of a true browsing user on a website is disclosed. The invention allows for the collection of data regarding the evolving threat landscape created by online attackers. The system and method fingerprint user behavior to detect differences between a local user, a remote/foreign user, and an automated script. The system then covertly transmits that information back to a financial institution client without giving online attackers the opportunity to notice such transmittal. Certain embodiments of the invention also correspond with the browsing user to validate their identity. The claimed system and method proactively reveal attackers and attack ploys, additionally enabling institutions and security consultants to adapt to attacks in an automated fashion.

Trustworthy systems require that code be validated as genuine. Most systems implement this requirement prior to execution by matching a cryptographic hash of the binary file against a reference hash value, leaving the code vulnerable to run time compromises, such as code injection, return and jump-oriented programming, and illegal linking of the code to compromised library functions. The Run-time Execution Validator (REV) validates, as the program executes, the control flow path and instructions executed along the control flow path. REV uses a signature cache integrated into the processor pipeline to perform live validation of executions, at basic block boundaries, and ensures that changes to the program state are not made by the instructions within a basic block until the control flow path into the basic block and the instructions within the basic block are both validated.
