Abstract:

A system of verifying a purported registrant's ownership or control of a payment instrument includes a communication device, a memory and a processor coupled to the communication device and to the memory. A payment instrument verification module stored in the memory and executable by the processor is adapted to receive information relating to the payment instrument from a registrant, initiate a financial transaction involving the payment instrument via the communication device, generate a dispute amount for the financial transaction, receive via the communication device a notification from a financial institution of the registrant that the financial transaction has been disputed by a comparison amount and compare the comparison amount with the dispute amount for purposes of verifying the payment instrument.

Assignee:

Visa U.S.A. Inc. - San Francisco CA

International Classification:

G06Q 40/00

US Classification:

705 35, 705 44

Abstract:

An address of a computing device for conducting a transaction with a merchant on an account of an account holder is used to obtain display attributes of the computing device. An authentication request is formatted using the obtained display attributes of the computing device. The formatted authentication request is sent for delivery to the logical address of the computing device. In response to the formatted authentication request, authentication information for the account holder is received from the logical address of the computing device. A validation attempt is performed on the received authentication information for the account holder. If the received authentication information for the account holder was successfully validated by the performance of the validation attempt, the authentication response is transmitted for delivery to a logical address for the merchant.

Timothy Lee - San Francisco CA, US

Assignee:

Visa International Service Association, A Delaware Corporation - Foster City CA

International Classification:

G06F017/60

US Classification:

705044000

Abstract:

An account authentication service where a trusted party verifies an account holder's identity for the benefit of a requestor during an online transaction. The account authentication involves requesting a password from the account holder, verifying the password, and notifying the requestor whether the account holder's authenticity has been verified. An alternative embodiment of the account authentication service includes a value-adding component where information about a customer is shared with a value-adding party. The customer information is rich in detail about the customer since it is collected by each of the parties in the account authentication process. The value-adding party can then use this information in various manners. All of the parties involved can benefit from sharing the customer information. The value-adding party can be, for example, a merchant, a shipper, a security organization, or a governmental organization. A transaction identifier identifies a specific transaction between a customer, a merchant, and the customer information.

International Classification:

H04M 3/16

US Classification:

455410000

Abstract:

A method and system for performing a secure transaction are disclosed. A service provider system may receive an account identifier and a one-time passcode from a user system via a communication network. The service provider system may determine whether the one-time passcode is valid. If the one-time passcode is valid, the service provider system may transmit a personal assurance message to the user system via the communication network. If the personal assurance message is verified, the service provider may receive a password from the user system via the communication network and determine whether the password is valid. If the password is valid, the user system and the service provider system may then perform a secure transaction.
