Abstract: A method being implemented via execution of computing instructions configured to run at one or more processors and stored at one or more non-transitory computer-readable media. The method can include receiving, at a transaction system being situated along a proxy communication channel extending from a point-of-sale terminal of a first entity to a mobile wallet provider, an encrypted transaction code. The encrypted transaction code can be generated and sent to the point-of-sale terminal by a mobile device that runs a mobile application associated with the mobile wallet provider. The mobile device receives from a point-of-sale terminal an identifier of the first entity, a transaction amount of a transaction, and a transaction identifier for the transaction, receives an authorization from a user of the mobile device for the transaction while the user is at the point-of-sale terminal, and determines that the mobile device is unable to communicate with the mobile wallet provider.

Abstract: A method being implemented via execution of computing instructions configured to run at one or more processors and stored at one or more non-transitory computer-readable media. The method can include receiving a preauthorization code at a mobile device while the mobile device is in data communication with a mobile wallet provider. The preauthorization code can include a preauthorization amount, an expiration time, and a digital signature. The method also can include storing the preauthorization code in the mobile device. The method additionally can include receiving, at the mobile device, an authorization from a user of the mobile device for a transaction having a transaction amount while the user is at a point-of-sale terminal of a first entity. The method further can include determining that the mobile device is unable to communicate with the mobile wallet provider. The method additionally can include verifying that the transaction amount is less than or equal to the preauthorization amount.

Abstract: A method being implemented via execution of computing instructions configured to run at one or more processors and stored at one or more non-transitory computer-readable media. The method can include receiving a transaction amount and a preauthorization code from a first entity. The preauthorization code can include a preauthorization amount, an expiration time, and a digital signature. The transaction amount is for a transaction authorized by a user of a mobile device at a point-of-sale terminal of the first entity. The transaction amount is less than or equal to the preauthorization amount. The mobile device received the preauthorization code and stored the preauthorization code in the mobile device while the mobile device was in data communication with a mobile wallet provider. The mobile device provided a transaction code to the point-of-sale terminal while the mobile device was unable to communicate with the mobile wallet provider.

Abstract: A method including receiving a request from a provider to perform a provisioning of an account to a mobile wallet operating on a mobile device. The method also can include sending an inquiry to a risk determination system to authenticate the provisioning of the account to the mobile wallet. The risk determination system can generate a fraud risk level by applying business rules and one or more statistical modeling techniques. The method additionally can include receiving from the risk determination system a response based on the fraud risk level. The method further can include determining whether to proceed with the provisioning of the account to the mobile wallet based at least in part on the response received from the risk determination system. The method additionally can include providing a token to the provider in response to the request to perform the provisioning of the account to the mobile wallet when the fraud risk level is below a predetermined threshold. Other embodiments are provided.

Abstract: A method including receiving an inquiry from a provider to authenticate a provisioning of an account to a mobile wallet. The method also can include determining device ownership information for a mobile device that operates the mobile wallet, account ownership information for the account, device risk information associated with the mobile device, and account risk information associated with the account. The method additionally can include determining an ownership correlation between the device ownership information and the account ownership information. The method further can include generating a fraud risk level by applying business rules and one or more statistical modeling techniques. The method additionally can include providing a response to the provider based on the fraud risk level. Other embodiments are provided.

Abstract: A method including receiving a request from a mobile wallet operating on a mobile device to perform a provisioning of an account to the mobile wallet. The method also can include generating account information about the account. The method additionally can include generating device information about the mobile device. The method further can include sending an inquiry to a risk determination system to authenticate the provisioning of the account to the mobile wallet. The risk determination system can generate a fraud risk level by applying business rules and one or more statistical modeling techniques. The method additionally can include receiving from the risk determination system a first response based on the fraud risk level. The method further can include determining whether to proceed with the provisioning of the account to the mobile wallet or to perform an additional verification based at least in part on the first response received from the risk determination system.

Abstract: A method including receiving, at a mobile device being used by a consumer, a transaction code from a point-of-sale terminal at a store of a merchant. The transaction code can include a merchant public identifier being associated with the merchant, a payment amount for one or more items to be purchased from the merchant by the consumer in a transaction, a transaction identifier for the transaction, and a digital signature. The method also can include verifying the digital signature for the transaction code.

Abstract: A method including receiving, at a transaction system from a first entity, a request including a merchant public identifier associated with a merchant. The transaction system can be in data communication with a first financial institution that maintains a first account of a consumer and a second financial institution that maintains a second account of the merchant. The transaction system can be maintained by an entity that is different from the merchant, the first financial institution, and the second financial institution. The consumer can use a mobile device at a store of the merchant to pay for one or more items in a transaction. The mobile device can receive a transaction code from a point-of-sale terminal at the store. The transaction code can include a transaction identifier, a payment amount for the transaction, the merchant public identifier, and a digital signature. The transaction code can be verified by the mobile device using the digital signature of the transaction code.

Abstract: A method including determining, at a point-of-sale terminal at a store of a merchant, a payment amount for one or more items to be purchased from the merchant by a consumer in a transaction. The method also can include generating a transaction code including a merchant public identifier, the payment amount, a transaction identifier for the transaction, and a digital signature.

Abstract: The security of a transaction conducted at a mobile device, using a one-time password to authenticate the mobile device user, is enhanced by requiring that the mobile device also be authenticated by providing a valid mobile device ID. A security server that provides the one-time password to the mobile device also provides a hyperlink that, when selected, causes a mobile device ID, such as an IMSI, to be retrieved from a SIM in the mobile device The retrieved mobile device ID is then sent to the security server. A database associated with the security server stores valid mobile device IDs, and compares the retrieved mobile device ID from the mobile device to the valid mobile device ID for that mobile device stored in the database. In alternative embodiments, the mobile device is authenticated without the use of a one-time password.
