Abstract

An authentication method capable of logging in a desired server which requires user authentication in a short time in a simple manner, while improving security of an ID and a password is provided. A user operates a portable terminal 1, and then selects a screen memo function so as to display a screen memo list on a display 2. The user selects a server number of a desired server from this screen memo list. Subsequently, a key code input screen is displayed, and the user inputs a key code used to log in the server from an input key 4, whereby a log-in process is carried out, and after the completion of the log-in process, the portable terminal 1 displays Compact HTML received from the server on the display 2.

Claims

1. An authentication method of a portable terminal, wherein a Compact HTML-adaptable portable terminal equipped with a screen memo function capable of saving thereinto a source file of Compact HTML logs into various kind of servers which require user authentication and are provided on an information communication network, comprising the steps of:

inputting a key code based upon said screen memo function into said portable terminal, to which both user information and said key code corresponding to said user information have been previously registered, said user information being used when said predetermined server executes an authentication process of said portable terminal;

transmitting said user information corresponding to said key code from said portable terminal to said predetermined server in response to the inputting of said key code; and

logging in said predetermined server which receives said user information and executes the authentication process based upon said user information by said portable terminal.

2. The authentication method of a portable terminal as claimed in

claim 1

wherein:

said user information is composed of both a user ID and a password, which are used to log in said predetermined server.

3. The authentication method of a portable terminal as claimed in

claim 2

wherein:

contents of such data as the user ID, the password, and the key code, which have been registered in said screen memo in said portable terminal, are constituted in such a manner that said data contents cannot be observed from the outside of said portable terminal.

4. The authentication method of a portable terminal as claimed in

claim 1

wherein:

said key code is composed of a numeral having a plurality of digits.

5. The authentication method of a portable terminal as claimed in any one of the preceding

claims 1

to

4

wherein:

said various kind of servers which require said user authentication and are provided on the information communication network are connected via a gateway server to said portable terminal.
