Abstract

The present invention generally relates to a wireless banking system and a wireless banking method using a mobile phone. The mobile phone includes a smart card inputting smart card information consisting of bank account information, log information, and an authentication key. A card applet is provided which operates the smart card information. The banking service uses a common full text and individual full texts used for banking transactions, prepared through the smart card information and an input of the mobile phone. An encoding/decoding module is provided for encoding the banking service full text and decoding the response to the banking service full text by using a session key; and a card manager communicating the application with the smart card.

Claims

1. A mobile phone for conducting wireless banking transactions in connection with a server system of a bank through a wireless communication network, comprising:

a smart card inputting smart card information consisting of bank account information, log information, and an authentication key, and having a card applet which operates the smart card information;

one banking service full text consisting of a common full text and individual full texts used for banking transactions being prepared through the smart card information and an input of the mobile phone;

an application completing a transaction after receiving a response to the one banking service full text while transmitting the banking service full text, and having an encoding/decoding module for encoding the one banking service full text and decoding the response to the banking service full text by using a session key, wherein a new session key is allocated to each banking service full text when said application transmits each banking service full text; and

a card manager communicating the application with the smart card.

2. A wireless banking system which enables a mobile phone to conduct wireless banking transactions in connection with a server system of a bank through a communication network, comprising:

the mobile phone, comprising;

a smart card inputting smart card information consisting of bank account information, log information, and an authentication key, and having a card applet which operates the smart card information;

one banking service full text consisting of a common full text and individual full texts used for banking transactions being prepared through the smart card information and an input of the mobile phone;

an application completing a transaction after receiving a response to the one banking service full text while transmitting the banking service full text, and having an encoding/decoding module for encoding the one banking service full text and decoding the response to the banking service full text by using a session key, wherein a new session key is allocated to each banking service full text when said application transmits each banking service full text; and

a card manager communicating the application with the smart card; and

the bank server system receiving the banking service full text in connection with the mobile phone through the communication network, and transmitting a response to the banking service full text to the mobile phone, comprising;

a wireless banking server exchanging a session key with the mobile phone and decoding the banking service full text while encoding the response to the banking service full text by using the session key.

3. A wireless banking method using a mobile phone, comprising the steps of:

a first step of preparing one banking service full text consisting of a common full text and individual full texts by using information on a smart card in the mobile phone where the smart card containing banking transaction information therein is attached;

a second step of exchanging a session key during a handshake process by connecting the mobile phone with the wireless banking server;

a third step of encoding the banking service full text and transmitting the encoded banking service full text to the wireless banking server by using the session key;

a fourth step of the wireless banking server decoding the banking service full text by using the session key to activate the banking service; and

a fifth step of the wireless banking server encoding an activated result of the banking service by using the session key, and transmitting the encoded result to the mobile phone, wherein a new session key is allocated to each banking service full text when said application transmits each banking service full text.

4. The wireless banking method of claim 3, wherein the first step comprises the steps of:

authenticating through authentication information of the smart card;

identifying the banking transaction information contained in the smart card; and

preparing the one banking service full text.

5. A wireless banking method using a mobile phone, comprising the steps of:

a first step of preparing one banking service full text consisting of a common full text and individual full texts by using information on a smart card in the mobile phone where the smart card containing banking transaction information therein is attached;

a second step of exchanging a session key during a handshake process by connecting the mobile phone with the wireless banking server;

a third step of encoding the banking service full text and transmitting the encoded banking service full text to the wireless banking server by using the session key;

a fourth step of the wireless banking server decoding the banking service full text by using the session key to activate the banking service; and

a fifth step of the wireless banking server encoding an activated result of the banking service by using the session key, transmitting the encoded result to the mobile phone, input of the mobile phone to initiate a further transaction after transmission of the response being a new session with a new session key being allocated.
