Abstract

A user authentication method includes transmitting a number of the mobile communication terminal, a user identifier (ID), and a unique number (PW); at the web server, storing the number of the mobile communication terminal, the user identifier (ID), and the unique number (PW); at a mobile communication terminal registered in the web server, transmitting location information of the mobile communication terminal; at the web server, storing a table in which the location information is mapped together with the number of the mobile communication terminal, the user identifier (ID), and the unique number (PW); and when the web server receives an access request from the mobile communication terminal registered in the web server, at the web server, confirming location information of the mobile communication terminal and comparing the location information of the mobile communication terminal with the table.

Claims

1. A user authentication method using location information for access of a mobile communication to a web server, the method comprising:

at the mobile communication terminal, transmitting a number of the mobile communication terminal, a user identifier (ID), and a unique number (PW);

at the web server, storing the number of the mobile communication terminal, the user identifier (ID), and the unique number (PW);

at a mobile communication terminal registered in the web server, transmitting location information of the mobile communication terminal;

at the web server, storing a table in which the location information is mapped together with the number of the mobile communication terminal, the user identifier (ID), and the unique number (PW); and

when the web server receives an access request from the mobile communication terminal registered in the web server, at the web server, confirming location information of the mobile communication terminal and comparing the location information of the mobile communication terminal with the table.

2. The user authentication method using location information according to claim 1, further comprising, at the web server, transmitting a message informing that the table has been stored in the mobile communication terminal.

3. The user authentication method using location information according to claim 1, wherein the transmitting of the location information of the mobile communication terminal comprises

acquiring a location information value based on a global positioning system (GPS) of the mobile communication terminal and transmitting the location information value, or

receiving a location information value directly from a user of the mobile communication terminal and transmitting the location information value.

4. The user authentication method using location information according to claim 1, wherein in the storing of the table in which the location information is mapped,

as the location information, location information storing a table in which at least one location information value acquired based on the GPS of the mobile communication terminal or at least one location information value input directly from the user of the mobile communication terminal is received and mapped is used.

5. The user authentication method using location information according to claim 1, wherein the comparing of the location information of the mobile communication terminal with the table comprises:

at the mobile communication terminal, requesting the web server to perform first access authentication using the number of the mobile communication terminal, the user identifier (ID), and the unique number (PW);

at the web server, performing the first access authentication based on the number of the mobile communication terminal, the user identifier (ID), and the unique number (PW) with reference to the table and requesting the mobile communication terminal to transmit the location information;

at the mobile communication terminal, transmitting the location information of the mobile communication terminal to the web server; and

at the web server, comparing the received location information with the table and performing second access authentication on the mobile communication terminal when the location information is matched with the location information in the table.

6. The user authentication method using location information according to claim 5, wherein in the requesting of the mobile communication terminal to transmit the location information, the location information for performing the first access authentication when the number of the mobile communication terminal, the user identifier (ID), and the unique number (PW) are matched with information in the table is used.

7. The user authentication method using location information according to claim 5, wherein the transmitting of the location information of the mobile communication terminal comprises

acquiring a location information value based on a global positioning system (GPS) of the mobile communication terminal and transmitting the location information value, or

receiving a location information value directly from a user of the mobile communication terminal and transmitting the location information value.

8. The user authentication method using location information according to claim 5, wherein, in the performing of the second access authentication,

when a location information value acquired based on a GPS of the mobile communication terminal or a location information value input directly from a user of the mobile communication terminal is matched with information in the table, location information for performing the second access authentication so that a service is provided from the web server is used.

9. The user authentication method using location information according to claim 1, further comprising, at the web server, transmitting a message informing the mobile communication terminal that the second access authentication has been performed to the mobile communication terminal.

10. The user authentication method using location information according to claim 9, further comprising:

by a user of the mobile communication terminal, requesting the web server to release access authentication of the mobile communication terminal when the received message is transmitted due to illegal access; and

at the web server that is requested to release, releasing the first access authentication and the second access authentication on the mobile communication terminal.
