Abstract
Abstract An electronic commerce process that facilitates online transactions among multiple participants, that prevents consumer fraud due to pirated payment card numbers, with calculated risk, involving at least one trusted payment card host (3), where buyer's payment card number is registered and corresponding secret keys are set up. The buyer (1b) initiates an online transaction by selecting a host from a list of hosts that served by the seller's web server (2a). Then, the buyer participant (1a) sends an order online (4), SSL encrypted. The seller participant (2a) receives and decrypts the order, confirms the availability of ordered items, assigns an orderID to the order, and sends a response (5a), SSL encrypted, to the buyer participant (1a) with the assigned orderID. The buyer participant (1a) encrypts and notifies the selected host (3) of this order and orderID, and authorizes the payment (6a) using secret keys. At the same time, the seller participant also encrypts and sends payment approval request (7) for this orderID through the host. The host (3) decrypts and matches up the orderID, retrieves the secret keys, and hashes to obtain the corresponding payment card number. The host then encrypts and send for payment authorization (8a) from the payment card issuer with the payment card number, through payment clearing network. Upon receiving and decrypting the response (9) back from the payment card issuer, the host (3) encrypts and notifies (10a) the seller participant (2a) of the card issuer's response (9) for the orderID. After fulfilling the order (11,12), the seller participant encrypts and sends for payment capturing (13a) for this order with orderID, through the host and payment network (14a,15,16).
