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.

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.
