Abstract: Methods and systems for conducting a secure transaction over a network using one or more gateway servers. The methods include receiving a request from a consumer, sending the request to a merchant, and receiving, from the merchant, a payment order associated with the request. The payment order is received via a merchant programmable user interface. The methods also include confirming the payment order to transform the payment order to a confirmed payment order, sending the confirmed payment order to a user, and receiving, from the user, a payment authorization associated with the confirmed payment order, and the payment authorization being received via a consumer programmable user interface. The payment authorization from the user includes a secure, encrypted, Internet Protocol (IP) message using encryption hashed with public and private key management. The methods also include performing a transaction in accordance with the payment authorization.
