As described above, according to the present invention, the user of the mobile communication terminal can perform a financial transaction by simply creating and transmitting a text message in a specific format in the same manner as sending a text message to another person.

Since text messages have a lower cost than other communication methods of a mobile communication terminal, text messages have a low cost in processing financial transactions.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Financial transaction system using a text message transmission and reception according to an embodiment of the present invention is a financial transaction mobile communication terminal 100, financial transaction relay server 200, bank company financial transaction processing server ( 300). Here, the financial transaction relay server 200 and the bank company financial transaction processing server 300 does not necessarily need to be configured with physical hardware, but may be configured by software. Furthermore, although the term "server" is used for both the financial transaction relay server 200 and the banking company financial transaction processing server 300, it does not necessarily need to be configured in an independent form, and any one may be configured as another software module. It may be. A more detailed description thereof will be provided later.

The financial transaction mobile terminal 100 refers to a portable wireless communication device, such as a mobile phone, PDA (Personal Digital Assistants) having a text message transmission function, in particular used for financial transactions' mobile communication terminal 100 for financial transactions It's not just used for financial transactions.

The financial transaction mobile communication terminal 100 transmits a text message containing the financial transaction information of a predetermined format prepared by the user, using the transaction bank identification number selected by the user as the text message destination number.

Herein, the selection of the bank identification number by the user includes a case where the bank ID is selected by the user as well as being directly input by the user.

For example, the bank identification number may include a combination of special characters and numbers. For example, the identification number of Shinhan Bank may be '# 5858'. Here, Shinhan Bank as a bank and '# 5858' as its identification number are just examples, and can be changed as many as possible.

Although not specifically illustrated in the present embodiment, the mobile communication network is provided with a Short Message Service Center (SMSC), and performs a function of delivering a text message transmitted from the mobile communication terminal to a corresponding text message destination number. Since the transmission process is well known, a detailed description thereof will be omitted.

In this embodiment, although the called number of the text message transmitted from the mobile communication terminal corresponds to the identification number of the specific bank, the financial transaction relay server 200 serves as a gateway for the text message to each bank as described below. Since the SMSC of the mobile communication network delivers a text message transmitted from the mobile communication terminal to the financial transaction relay server 200.

The financial transaction relay server 200 generates a financial transaction request message according to a text message received from the mobile communication terminal 100 for financial transaction, and sends the generated financial transaction request message to a transaction bank identification number (ie, a text message incoming). Number corresponding to the banking company financial transaction processing server 300. To this end, the financial transaction relay server 200 should store data in which the bank identification number and the bank company financial transaction processing server 300 address (for example, IP address: Internet Protocol address) match.

In this embodiment, the financial transaction relay server 200 generates a predetermined message (for example, a financial transaction request message) by modifying a text message received from the mobile terminal to generate another message including additional information. In addition, it is meant to include the text content of the text message received from the mobile communication terminal as it is, and to change only the form to match the communication protocol with the banking company financial transaction processing server 300. That is, it also includes performing a kind of forwarding function.

Furthermore, messages generated by the financial transaction relay server 200 such as a financial transaction request message may be made of text or binary data in a format different from that of a text message transmitted from the mobile communication terminal 100 for financial transactions, and also a bank. It may also include only predetermined information or data contracted with the private financial transaction processing server 300.

That is, the format or form of the information generated by the financial transaction relay server 200 and transmitted to the banking financial transaction processing server 300 may be variously changed.

In addition, the financial transaction relay server 200 transmits a text message according to the response of the banking company financial transaction processing server 300 to the mobile communication terminal. This process also requires the operation of a device related to message transmission, such as a short message transmission center provided in a mobile communication network, but the detailed description is omitted since it is well known.

Sending a text message from a mobile terminal to a specific server is called a mobile originated (MO) service, and vice versa for sending a text message from a specific server or a specific computer to a mobile terminal. Called service. For example, sending a text message to a mobile communication terminal so that the message is displayed at the bottom of the TV cable broadcasting screen is a MO service, and accesses a specific web site using a computer to send a text message to another mobile terminal. The transmission corresponds to the MT service.

Therefore, in the present embodiment, transmitting the text message to the financial transaction relay server 200 by the mobile communication terminal 100 for a financial transaction may correspond to an MO service, and a predetermined text message may be transmitted from the financial transaction relay server 200. What is transmitted to the mobile communication terminal 100 for financial transactions may correspond to the MT service.

Communication between the financial transaction relay server 200 and the bank company financial transaction processing server 300 may be encrypted.

An example of a functional block configuration of the financial transaction relay server 200 is illustrated in FIG. 2A.

As shown in the figure, the financial transaction relay server 200 may include an MO interface unit 210, an MT interface unit 220, an encryption communication module 230, and a database unit 240.

The MO interface unit 210 performs a function of receiving a text message from the mobile communication terminal 100 for financial transactions, and the MT interface unit 220 receives a text message according to the response of the banking company financial transaction processing server 300. It performs a function of transmitting to the mobile communication terminal 100 for financial transactions.

The database unit 240 stores a bank company financial transaction processing server 300 address, for example, an IP (Internet Protocol) address, which matches a text message called party number received from a mobile communication terminal.

The encryption communication module 230 performs an interface function for communication with the banking company financial transaction processing server 300 and simultaneously encrypts the communication contents. The cryptographic communication module 230 may generate a random number for cryptographic communication. When the encryption of the communication data is not necessary, only an interface for communication with the banking company financial transaction processing server 300 may be provided instead of the encryption communication module 230.

Meanwhile, the banking company financial transaction processing server 300 includes a database including user account data in which a mobile communication terminal unique number and an account number match, and finance from a financial transaction request message received from the financial transaction relay server 200. A unique number of the mobile communication terminal 100 for transaction is extracted, and an account number corresponding to the extracted unique number of the mobile communication terminal 100 for financial transaction is extracted from the database.

The bank account corresponding to the extracted account number is processed by the financial transaction request message received from the financial transaction relay server 200.

Here, processing the financial transaction not only allows the actual account balance to be transferred to another account, such as an account transfer, but also extracts the corresponding information so that the customer can view or verify the account information and transmits it to the mobile communication terminal 100 for financial transaction. It also includes.

In addition, the banking company financial transaction processing server 300 needs to receive predetermined information, for example, an account password, a service use password, etc. from the mobile communication terminal according to the financial transaction to be processed, a message for guiding this. Can be generated. At this time, by generating and forwarding a new reply number, the mobile communication terminal 100 for financial transactions and the connection for financial transactions may be maintained.

Here, maintaining the connection state between the banking company financial transaction processing server 300 and the mobile communication terminal 100 for financial transactions does not mean that the communication channel or line is actually kept occupied, but for financial transactions. This means that it is possible to confirm that the text message transmitted from the mobile communication terminal 100 includes a text message including predetermined information (for example, an account password, etc.) associated with the previously requested financial transaction. In other words, it also means to perform the function to overcome the non-connectivity of text message transmission and reception. A more detailed description thereof will be described later.

An example of a functional block configuration of a banking company financial transaction processing server 300 that performs the functions described above is illustrated in FIG. 2B.

As shown in the figure, the banking company financial transaction processing server 300 includes a message interpreter 340, a message generator 330, a reply number generator 320, a database 350, and an encryption communication module 310. It may be configured to include).

The message interpreter 340 performs a function of interpreting and processing a financial transaction request message received from the financial transaction relay server 200. For example, the unique number of the mobile communication terminal 100 for a financial transaction from the financial transaction request message. And extract an account number corresponding to the extracted unique number of the mobile communication terminal 100 for financial transactions from the database.

In addition, the message analyzing unit 340 analyzes the message transmitted from the financial transaction mobile communication terminal 100 from the financial transaction request message to determine which financial transaction is requested, and further includes whether a security card number or the like is included. Judge.

That is, the text message transmitted from the mobile communication terminal 100 for financial transactions is prepared in a predefined format, and the message analyzer 340 determines what information is included in the text message based on the predefined format. Interpret / Judge

The message generator 330 generates a message for requesting additional information necessary for a financial transaction, or performs a function for generating a message after the financial transaction is processed.

The reply number generator 320 performs a function of generating a reply number for maintaining the connection state for each financial transaction.

The database unit 350 includes information such as account information and transaction history of each customer. In particular, the database unit 350 includes user account data in which a unique ID and an account number of the mobile communication terminal match.

The encrypted communication module 310 configures a communication interface with the financial transaction relay server 200 and further performs a function of enabling encrypted communication. Here, the encryption communication module 310 may be connected to the encryption communication module 230 of the financial transaction relay server 200 by a dedicated line. That is, when the bank company financial transaction processing server 300 and the financial transaction relay server 200 are operated by different operators, for example, the bank company financial transaction processing server 300 and the financial transaction relay server 200 Although it may be connected to each other through the Internet network, when the bank company financial transaction processing server 300 and the financial transaction relay server 200 is operated / managed by the same operator, for example, the bank company financial transaction processing server 300 and The financial transaction relay server 200 may be connected by a dedicated line to exclude the connection of another network.

Furthermore, the functional block configuration of the bank company financial transaction processing server 300 and the financial transaction relay server 200 is for explaining the functions of the bank company financial transaction processing server 300 and the financial transaction relay server 200. It is just one example, and the bank company financial transaction processing server 300 and the financial transaction relay server 200 may be configured as one hardware. In this case, the cryptographic communication modules 230 and 310 of FIGS. 2A and 2B configured in the banking company financial transaction processing server 300 and the financial transaction relay server 200 may also be omitted internally.

In the above embodiment, the financial transaction mobile communication terminal 100 communicates with the financial transaction relay server 200 via a base station and a mobile communication network, and the financial transaction relay server 200 is a banking company financial transaction processing server through the Internet network. It is configured to communicate with the 300, but the configuration of the communication network between each device can be changed as much as of course.

Hereinafter, a method of controlling a financial transaction system using text message transmission and reception according to an embodiment of the present invention will be described with reference to FIGS. 3A to 4.

First, an example of a process of transferring money using a text message will be described with reference to FIG. 3A.

The financial transaction mobile communication terminal 100 user inputs an account transfer text message in a specific format as shown in FIG. 5 (a) so that the mobile communication terminal generates a text message (step S1).

In this embodiment, each field is separated by using a delimiter '*', '43180201135963' entered in the first field corresponds to the other party's account number to be transferred, and 'Kookmin Bank' in the second field is The other bank to which the account is to be transferred, and '53000' in the third field means the amount to be transferred.

As such, the user of the financial transaction mobile communication terminal 100 which has created a text message for bank transfer enters the identification number of his or her bank in the recipient of the text message. Here, the identification number of the bank may be a combination of special characters and numbers.

In FIG. 5 (a), the transaction bank identification number is input as '# 5858', and '# 5858' may correspond to, for example, Shinhan Bank.

When requesting the transmission of the text message created using the transaction bank identification number as the called number, the mobile communication terminal transmits the text message to the mobile communication network (step S3).

In order to transmit a text message, a text message center, such as a short message center of a mobile communication network, needs to go through a device that is responsible for delivering a text message.

However, the text message transmission process according to the present embodiment may be regarded as a kind of MO service in that the text message transmission process is transmitted from the mobile communication terminal to a server on a predetermined network, unlike the text message transmission process between general mobile communication terminals.

The financial transaction relay server 200 receiving the text message transmitted from the mobile communication terminal 100 for financial transaction is the address of the bank company financial transaction processing server 300 corresponding to the called number (that is, the transaction bank identification number). For example, IP Address: Internet Protocol Address) is extracted (step S5).

To this end, the financial transaction relay server 200 should store data in which the bank identification number and the bank company financial transaction processing server 300 address match.

Subsequently, the financial transaction relay server 200 generates and encrypts a financial transaction request message (step S7), wherein the financial transaction request message is a text message received from the mobile communication terminal 100 for financial transaction and the mobile communication for financial transaction. Terminal 100 may include a unique number. Here, the financial transaction request message generated by the financial transaction relay server 200 does not necessarily have to be configured in the form of a text message transmitted from the mobile communication terminal 100 for financial transactions as described above. 300 only need to be in a predetermined data format for the transmission and reception of predetermined information.

The financial transaction mobile terminal 100 unique number may be a phone number of the financial transaction mobile communication terminal 100 for transmitting a text message, or may be a unique serial number of the terminal, such a terminal identification number is a text When the message is transmitted, it is preferable to use a forgery or forgery among those transmitted to the financial transaction relay server 200 through the mobile communication network. When the unique number of the financial transaction mobile communication terminal 100 is a phone number, the financial transaction relay server 100 may be transmitted to the financial transaction relay server 200 by the calling number display service.

Receiving the encrypted financial transaction request message (step S9), the banking company financial transaction processing server 300 decrypts the financial transaction request message and analyzes the contents (step S11).

As such, the encrypted transaction is performed between the financial transaction relay server 200 and the banking company financial transaction processing server 300 so that the confidentiality of the communication contents can be guaranteed even if the contents are intercepted in the middle. Therefore, when the financial transaction relay server 200 does not need to encrypt all the information, the financial transaction relay server 200 may partially encrypt only the content that requires confidentiality.

As the encryption method between the financial transaction relay server 200 and the banking company financial transaction processing server 300, a symmetric key encryption method or a public key encryption method may be used. In the case of using the symmetric key encryption method, the financial transaction relay server 200 may be used. And the bank company financial transaction processing server 300 must be provided with the same pre-generated secret key, when using a public key encryption method, a mutual public key exchange process is further required.

The bank company financial transaction processing server 300 analyzing the financial transaction request message first processes a user authentication confirmation based on the unique number of the mobile communication terminal 100 for financial transaction included in the financial transaction request message (step S11).

That is, the banking company financial transaction processing server 300 is provided with a database unit 350 including user account data matching the mobile terminal unique number and account number (step S8), the banking company financial transaction processing server ( 300 may perform a user authentication process by checking whether the unique number of the financial transaction mobile communication terminal 100 included in the financial transaction request message is registered in the database unit 350.

When the customer opens an account in the bank in order to ensure that the unique identification number and account number of the mobile communication terminal are matched and stored in the database 350, a process of applying by inputting a mobile communication terminal phone number or wireless Internet through a mobile communication terminal, etc. Joining process may be further included.

The banking company financial transaction processing server 300 may additionally check whether the user of the mobile communication terminal 100 for financial transaction is authorized to use the financial transaction service using a text message. That is, when the financial transaction service permission information using the mobile terminal unique number and the text message is matched and additionally stored in the database unit 350, the banking company financial transaction processing server 300 uses the matching information to perform financial transaction. It may be determined whether to perform financial transaction processing based on the text message transmitted from the mobile communication terminal 100.

When the user authentication is made, the bank company financial transaction processing server 300 checks the owner name corresponding to the counterpart account number included in the text message (that is, the financial transaction request message) through a communication through a financial communication network (not shown). (Step S15).

That is, referring to Figure 5 (a), the banking company financial transaction processing server 300 inquires who owns the account of the 'Kookmin Bank' account number '43180201135963' to the server provided to Kookmin Bank, etc. Check the owner's name. Since the process of checking who owns the account for the transfer of funds is generally known through a financial communication network, detailed description thereof will be omitted.

In the same way as described above, the bank company financial transaction processing server 300 confirming the owner name of the account receiving the transfer generates a reply number using a random number (step S17).

Here, the reply number corresponds to a called number for transmitting additional information later in the mobile communication terminal 100 for financial transactions, so as not to be duplicated in connection with a large number of financial transactions and to make it difficult for others to guess easily. Generated random numbers may be included.

The random number generated here may be generated by using random numbers generated for the encrypted communication when the random number is generated for the encrypted communication between the financial transaction relay server 200 and the banking company financial transaction processing server 300. The associated load can be reduced.

In this case, both the financial transaction relay server 200 and the bank company financial transaction processing server 300 may be configured to simultaneously generate and use a random number, which is generated by the financial transaction relay server 200 and then the bank company financial transaction. It may be configured to transmit to the processing server 300 for use.

The banking company financial transaction processing server 300 matches the generated reply number with the financial transaction progress and temporarily stores it (step S18). Here, the banking company financial transaction processing server 300 may also store and match the generated reply number with the telephone number of the financial transaction mobile communication terminal 100 requesting the financial transaction. The telephone number of the financial transaction mobile communication terminal 100 may correspond to, for example, a caller's telephone number delivered to the financial transaction relay server 200 by a conventional CID (Caller IDentification) service.

Subsequently, the banking company financial transaction processing server 300 generates an input request message for additional information (for example, a bank security card number) for bank transfer (step S19). Owner name and reply number may be included. And the called number of the additional information input request message may be a phone number of the mobile communication terminal 100 for financial transactions.

The reply number may be a combination of the extracted random number and the bank identification number. For example, when the extracted random number is '123456789', the reply number is '# 5858' which is a combination of the bank identification number '# 5858' and the random number '123456789'. Can be '.

Receiving the encrypted additional information input request message from the banking company financial transaction processing server 300 (step S21), the financial transaction relay server 200 first performs decryption processing (step S23).

Most of the information transmitted between the bank company financial transaction processing server 300 and the financial transaction relay server 200 may be encrypted as described above, but the encryption process may be omitted when the need for confidentiality is small. The same applies to the encryption process performed in the following steps.

The financial transaction relay server 200 generates the additional information input request text message based on the decoded additional information input request text message and transmits the generated text to the mobile communication terminal 100 for financial transaction (step S25). The reply number of the message is generated by the banking company financial transaction processing server 300 to be a reply number included in the additional information input request message.

An example of a screen of the financial transaction mobile communication terminal 100 that receives and displays additional information input request text message from the financial transaction relay server 200 is illustrated in FIG. 5 (b).

Referring to FIG. 5 (b), it can be seen that a message is displayed to transmit a text message including 'Hyungsoo Kim', the owner name of the account receiving the transfer, and a bank security card number for the transfer of the account. In addition, it can be seen that the reply number of the text message is '# 585812456789' described above.

Subsequently, when the user of the financial transaction mobile communication terminal 100 prepares a bank security card number as shown in FIG. 5 (c) and requests a transmission to the reply number, the financial transaction mobile communication terminal 100 transfers the account created by the user. The additional information text message is transmitted (step S27).

Here, the mobile communication network is set to be transmitted to the financial transaction relay server 200 for text messages to all reply numbers starting with '# 5858' (this is between the carrier and the company managing the financial transaction relay server 200). Can be made by a contract), and thus, the above-mentioned transfer account additional information text message is transmitted to the financial transaction relay server 200 using the called number '# 5858123456789'.

The financial transaction relay server 200 extracts the address of the bank company financial transaction processing server 300 to which the text message is to be transmitted, based on the incoming number of the received bank transfer additional information text message (step S29).

For example, when the information of the database unit 240 is configured so that all the called numbers beginning with '# 5858' are connected to the banking company financial transaction processing server 300 corresponding to Shinhan Bank, the banking company financial transaction processing server 300 may extract the IP address of the banking company financial transaction processing server 300 of Shinhan Bank for the text message having the called number '# 5858123456789'.

Subsequently, the financial transaction relay server 200 generates and encrypts a financial transaction request message including an account transfer additional information text message (ie, a bank security card number) (step S31) and transmits it to the banking company financial transaction processing server 300. (Step S33). In this case, the called number '# 5858123456789' is also included in the financial transaction request message.

The bank company financial transaction processing server 300 decodes the financial transaction request message received from the financial transaction relay server 200 and then analyzes or analyzes the corresponding message (step S35).

First, the banking company financial transaction processing server 300 determines whether there is a temporarily stored reply number that matches the called number included in the financial transaction request message (step S37). If there is a matching reply number, the bank company financial transaction processing server 300 may check what financial transaction processing was being performed.

Here, the banking company financial transaction processing server 300 for the financial transaction delivered through the financial transaction relay server 200, instead of determining whether the incoming number included in the financial transaction request message and the pre-stored reply number match. As a method of determining whether a reply number matching the telephone number (ie, the CID) of the mobile communication terminal 100 is pre-stored, the financial transaction status currently in progress with the mobile communication terminal 100 for financial transactions may be checked. That is, the information to be compared in order to maintain the connection state between the financial transaction mobile communication terminal 100 and the bank company financial transaction processing server 300 may be variously changed / configured.

That is, the banking company financial transaction processing server 300 is any financial processing is performed with the mobile communication terminal 100 for financial transactions when the incoming number of the financial transaction request message corresponds to the reply number previously generated and transmitted. We can confirm whether there was.

Accordingly, the banking company financial transaction processing server 300 adds '# 3658' (see FIG. 5 (c)) included in the financial transaction request message received as the called number to '# 5858123456789' before the bank transfer itself. You will see that it corresponds to the requested bank credit card number.

As such, the reply number generated by the banking company financial transaction processing server 300 serves to maintain a connection state between the banking company financial transaction processing server 300 and the mobile communication terminal 100 for financial transactions.

That is, the text message has a structure that transmits unilaterally from one side to the other, which makes it difficult to maintain the connection state. If the reply number is properly used as in this embodiment, the connection state can be maintained. .

In particular, a financial transaction requires a process of requesting and transmitting predetermined information for authentication processing. In this case, a reply number is used to maintain a connection state between the financial transaction mobile terminal 100 and the banking company financial transaction processing server 300. Can be used.

On the other hand, the bank company financial transaction processing server 300 when the bank security card number included in the financial transaction request message matches the security card number of the account associated with the unique number of the mobile communication terminal 100 for financial transactions (step S39). The requested account transfer processing is performed (step S41), and a transfer result message is generated and transmitted to the financial transaction relay server 200 (step S43). In this case, the called number becomes the phone number of the mobile communication terminal 100 for financial transactions, and since the financial transaction processing is completed, the reply number may be '# 5858' corresponding to the original bank identification number.

The financial transaction relay server 200 transmits the transfer result text message to the financial transaction mobile communication terminal 100 (step S45), and the financial transaction mobile communication terminal 100 displays it (step S47).

An example in which a transfer result text message is displayed on the mobile communication terminal 100 for a financial transaction is illustrated in FIG. 5 (d).

Accordingly, the user of the mobile communication terminal can make a money transfer from his financial account to another person's account by creating and transmitting a text message to his mobile communication terminal.

In the above embodiment, the financial transaction relay server 200 is only responsible for the communication relay between the financial transaction mobile communication terminal 100 and the bank company financial transaction processing server 300 and is transmitted from the financial transaction mobile communication terminal 100. Analyzing the actual content of the text message to the bank company financial transaction processing server 300 has been described as an example.
