Abstract: A system and method comprising receiving information corresponding to a prospective transaction by a user, computing a characteristic value for the user based at least in part on the information, and generating a score for at least one payment type based at least in part on the information and historical data about previous transactions, the at least one payment type corresponding to at least one computer-executed workflow for finalizing the prospective transaction. The system and method further comprising, determining, based at least in part on the score and the characteristic value, an interface to display to the user, the interface including functionality that enables the user to initiate execution of the at least one computer-executed workflow, and providing the interface to the user.

Abstract: Details associated with a transaction are received from a first computing device. An identity of a party to the transaction is determined. An address to which communications to the party can be directed and accessed via a second computing device is obtained, where the second computing device is associated with the party. Confirmation data specific to the transaction is generated. The confirmation data is provided, via the address, to the second computing device. Confirmation of receipt of the confirmation data is received from the party. A set of payment options is provided to the part. A selection of a payment option is received from the party, and notice that the transaction has been completed is provided to the first computing device.

Abstract: A system and method comprising receiving a request to access a first set of details associated with a first transaction conducted by a user, the request including first information that corresponds to a first asset under the control of the user, determining an identity of the user based at least in part on the first information, and identifying a second transaction likely to be associated with the user, the second transaction being associated with second information that corresponds to a second asset different than the first asset. The system and method further including requesting confirmation from the user that the second asset is under the control of the user, and, upon receiving the confirmation, associating the first and second transactions with the first and second information.

Abstract: A system and method comprising receiving information consequent to communication between a user and the computer system, performing one or more queries based at least in part on the information, and computing a set of frequency values for results of the one or more queries. The system and method further comprises determining at least one confidence score for the one or more queries based at least in part on an outcome of evaluating the set of frequency values against one or more sets of decision rules, and, based at least in part on the at least one confidence score, outputting at least one user identity associated with the at least one confidence score.

Abstract: In certain embodiments, systems and methods may authorize an online transaction over a data communications network, including receiving a request for a transaction from a user via the network where the transaction request relates to a purchase order. Some embodiments include receiving a user identifier, determining if the user identifier provides sufficient information about an identity of said user to fulfill the transaction, requesting additional user identifiers until it is determined that there is sufficient information to fulfill the transaction, and authorizing the transaction if there is sufficient information for transaction fulfillment.
