Patent

CA 2275561

A communication method for increasing security for information communicating between a user terminal and a service provider via a PPP (point-to-point protocol) server is disclosed. A dial-up connection is set up between the user terminal and the PPP server via a public network and an Internet access route is set up between the PPP server and the WWW server through the Internet. When card ID information is transferred between the user terminal and the service provider, a dial-up access route is set up between the PPP server and the dial-up server through the public network. The Internet access route is changed to the dial-up access route to transmit the card ID information through the dial-up access route. When processing of the card ID information has been completed, the dial-up access route is disconnected and changed back to the Internet access route.
