<p>An online method that prevents fraud due to pirated payment card numbers by utilizing SSL security techniques between a buyer (1a), a seller (2a), and a trusted payment card host (3) who has the buyers' payment card information and corresponding secret keys. The buyer (1a) initiates the transaction by utilizing a host (3) providing service to the seller's web server (2a). The buyer (1a) sends an encrypted order to the seller (2a), who assigns an order ID and sends an encrypted response to the buyer (1a) with the assigned order ID. The buyer (1a) then notifies the host (3) of this order, and authorizes the payment using secret keys. The seller (2a) sends payment approval request to the host (3). The host (3) matches up the order ID, retrieves the secret keys and hashes to obtain the corresponding payment card number. The host then requests payment authorization and notifies the seller (2a) of the card issuer's response.</p> |
