One-time password service system using mobile phone and authentication method using the same
First Claim
1. An one-time password service system comprising:
- an one-time password (OTP) server for generating and transmitting a query(a) for an authentication to transmit, receiving a response password N corresponding to the query(a), generating a one-time password M corresponding to the query(a), and performing the authentication when the one-time password M corresponds with the response password N;
a short message service (SMS) server for converting the query(a) transmitted from the OTP server into a text message including the query(a) and transmitting the generated text message;
an OTP terminal for detecting the query(a) in the transmitted text message from the SMS server and generating and displaying the response password N;
a personal communications device for transmitting the response password N to the OTP server when the response password N corresponding to the transmitted query(a) from the OTP server is input; and
a content offer server for providing to the personal communications device content corresponding according to the authentification.

10. A method of authentication using a one-time password (OTP) service system, the method comprising:
-
generating a query(a) for an authentication required to provide content in an OTP server, transmitting the query(a) to a personal communications device and to an SMS (short message service) server, and generating a one-time password M by using the query(a);
transforming, in the SMS server, the query(a) transmitted from the OTP server into a text message including the query(a), and transmitting the text message to an OTP terminal;
detecting, in the OTP terminal, the query(a) included in the text message transmitted from the SMS server, and generating a response password N using the query(a);
transmitting the response password N into the OTP server when the response password N is inputted to the personal communications device;
receiving, in the OTP server, the response password N to perform the authentication when the response password N is corresponds with the one-time password M; and
selectively, in the content offer server, providing corresponding content to the personal communications device according to the authentication. - View Dependent Claims (11, 12, 13)

14. A mobile phone capable of generating an one-time password (OTP), the mobile phone comprising:
-
a text message idenitificator for determining a type of a text message by using an identification value included in the text message when the text message is transmitted from a short message service (SMS) server, and determining whether the text message includes a query(a);
a query detector for detecting the query(a) from the text message when it is determined that the query(a) is included in the text message;
a password generator for generating a response password N corresponds to the detected query(a) and identifying information(b)allocated to the OTP mobile phone; and
a display unit for displaying the response password N. - View Dependent Claims (15, 16)
