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.
