Abstract: Generating and validating a subscription key based on subscription parameters associated with a jurisdiction file stored in a NVRAM, the subscription key having characters based on a subscription start date, a subscription term, a key generation date, and a cyclical redundancy check value. Parameters are extracted from the subscription key including the subscription start date, the subscription term, the key generation date, and the cyclical redundancy check value and are stored in a memory of the gaming machine. The key is checked by generating a local cyclical redundancy check value based on a MAC address of the gaming machine and one or more of the extracted parameters, and is validated when the local cyclical redundancy check value matches the cyclical redundancy check value extracted from the subscription key. The jurisdiction file may be updated during a RAM clear function during installation of the gaming machine.

Abstract: The different advantageous embodiments provide a system for managing license utilization comprising a client system, a number of message transport servers, and a number of license management servers. The client system is configured to generate a number of messages having information about usage associated with a project code or a business unit. The number of message transport servers replicates the number of messages. The number of messages is transmitted to a message transport server in the number of message transport servers. The message transport server receiving the number of messages replicates the number of messages to each message transport server. The number of license management servers has a number of license management services configured to listen for updates from the number of message transport servers. The updates are the number of messages replicated across the number of message transport servers.

Abstract: Aggregated transaction data from a transaction data provider may be encrypted and exchanged with a content item selection system using commutative encryption algorithms. The transaction data provider and content item selection system may utilize a set of common identifiers that are each encrypted using a respective commutative encryption algorithm of the transaction data provider or content item selection system. The other of the transaction data provider or content item selection system encrypts the single-encrypted common identifier using a respective commutative encryption algorithm to generate double encrypted common identifiers. The double encrypted common identifiers may be used to match a set of common identifiers with transaction data. The transaction data may be encrypted and/or may include random offset values.
