  • Terminal device and method for requesting user certification from host computer
    Patent number: 6425085
    Abstract: A terminal device generates and transmits to a host computer a user certification code formed by combining a unique password input by a user and a unique code stored in the terminal device when the host computer requests a password from the terminal device. The host computer uses the certification code to perform user certification. Thereby, if a password assigned to one user is used, the host computer cannot be accessed by a terminal device other than the user's terminal device. Thus, security can be maintained, even if another person knows the password.
