Abstract: PURPOSE: A method, systems, and a program, are provided to perform electronic transactions that includes the feature of a "thin" consumer's wallet by adding an issuer gateway and moving the credit/debit card authorization function from the merchant to the issuer. CONSTITUTION: A four-party protocol method includes the step of sending from a consumer's computer(202) a start messages(220) over an internet network to a merchant's computer(204). The merchant's computer then replies to the consumer's computer with a merchant message including a wallet initiation message(222), a merchant digital signature, and a digital certificate from an acquiring bank(208). The wallet initiation message includes a payment amount, an order description, a timestamp, and a nonce. This starts a consumer's wallet program in the consumer's computer in response to the wallet initiation message. The consumer's computer then sends a message(224) over the internet network including some consumer identity and authentication information, such as a user id and user password, plus the merchant message, to an issuer gateway(214) operating on behalf of an issuing bank(212). The issuer gateway verifies the merchant's signature to prove that the consumer is dealing with the actual merchant and validates the merchant's certificate and the acquirer's certificate to prove that the merchant and issuer share a common financial arrangement. The issuer gateway then verifies that the consumer's account is active and has sufficient funds and/or credit to support the payment amount.

Abstract: PURPOSE: Controlling device and method for a vehicle engine are provided to control position of an EGR(Exhaust Gas Recirculation) valve through arranging a negative pressure sensor on a vacuum pipe or a solenoid valve mixing unit between the engine and the EGR valve. CONSTITUTION: A device for controlling an engine is formed by a negative pressure detect instrument between the engine and an EGR valve for detecting negative pressure of the engine; a control instrument receiving a signal from the detect instrument for calculating a duty rate and a target negative pressure to output a duty control signal; and a drive instrument duty controlled by the duty control signal. Herein, the control instrument detects a first negative pressure for operating the target negative pressure and the first negative pressure. In case of the calculated value within an established tolerance range, the control instrument is returned to a main routine. Otherwise, a subtracted value of the first negative pressure from the target negative pressure decided to be over zero. Then, the control instrument calculates a second negative pressure by multiplying the target negative pressure to an added value of the first negative pressure and the tolerance value. Otherwise, the second pressure is calculated by multiplying the target pressure to a subtracted value of the tolerance value from the first pressure. The second negative pressure is converted into the target negative pressure for outputting the duty control signal.
