Abstract

A computer implemented system of automated intrinsic authorization of on-line electronic transactions is disclosed. The system involves the use of a merchant transaction tracking service that identifies the transaction, using a unique transaction identifier, and manages the authorization process. The merchant transaction tracking service also provides authentication of aspects of the transaction and its participants during the authorization process. The merchant need not contact the customer'"'"'s credit card company directly, as a communication that includes the transaction identifier is embedded in the merchant'"'"'s payment form. The payment form is transmitted to the customer, and then relayed to the credit card issuer. Authentication is provided automatically, using an encrypted certificate bearing the digital signature of the credit card issuer. The digital certificate is associated with the transaction identifier, and is transferred to the merchant transaction tracking service, which then verifies the transaction to the merchant.
