Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

1 is a block diagram showing an electronic tax invoice issuing system according to an embodiment of the present invention.

As shown, the mobile communication terminal 110 and the purchaser terminal 120 for issuing and issuing a tax invoice and issuing a request, approval or rejection of the tax invoice, and the mobile support for the wireless communication between the terminal (110, 120) An operation module unit which is connected to the communication network server 130 and the mobile communication network server 130, performs overall management of issuance, approval or approval rejection, printing, etc. of the electronic tax invoice and generates and converts a document form of the electronic tax invoice ( 150) and an authorized authentication server 140 that performs an authorized authentication procedure when the electronic tax invoice is issued.

The operation module unit 150 is a control system 156 that performs control related to issuing an electronic tax invoice of the present invention, and an authentication server 158 that performs an electronic signature and encryption function in association with the authorized authentication server 140. In connection with the mobile communication network server 130, an SMS server 154 for transmitting a short message and a call back-URL message, an enterprise resource management system (ERP) 164 that is previously implemented to manage all information of the enterprise. , A database management system (DBMS) for XML (166), the XML DBMS (166) and the enterprise resource management system (164) for easily modeling, storing, and retrieving an XML document. Because different data formats are handled in XML, XML Mapper 162 is provided as a converter to automatically generate XML / EDI document by acting as interface and data conversion function between each other. It is composed of an XML / EDI system 160 for securely transmitting documents handled on the Internet such as XML.

Reference numeral 152 denotes a web server 152 that provides a process for processing an electronic tax invoice in a website in association with a mobile communication network and an internet network.

Here, the tax invoice provided in the present invention is implemented as a complete electronic document through XML. That is, the operation module unit 150 is to define the process of issuing a tax invoice and manage while organizing related data.

Next, the process of issuing an electronic tax invoice according to the present invention configured as described above will be described in detail.

Here, the electronic tax invoice is notified from the seller mobile communication terminal 110 to the purchaser terminal 120 issuing the fact that the buyer confirms the electronic tax invoice, reject or approve the approval and request for correction When the pre-written electronic tax invoice from the purchaser terminal 120 is transmitted to the seller mobile communication terminal 110, the seller is divided into an issuing method for rejecting the approval or approval and requesting correction, respectively. This will be described with reference to 2b.

In addition, it is assumed that basic information of a buyer and a seller who receives the electronic tax invoice, such as a business registration number, is managed by the enterprise resource management system 164 or the XML DBMS 166.

2A is a flowchart illustrating a process of issuing an electronic tax invoice using a mobile according to an embodiment of the present invention.

First, when a transaction occurs for a specific item or the like between the seller and the buyer (ST200), the seller must issue a tax invoice to the buyer.

The tax invoice is prepared by the seller using his mobile terminal 110.

To this end, the seller operates his mobile communication terminal 110 to access the web server 152 associated with the control system 156 to directly create a tax invoice issuing menu, or to generate the transaction The XML DBMS 166 is searched for, selected, and created (ST202).

When the electronic tax invoice prepared directly in the issuing menu is transmitted to the XML DBMS 166 through a mobile communication network, the XML / EDI system 160 sends the electronic tax invoice or the XML DBMS 166 The selected electronic tax invoice is stored through encryption and digital signature through the authentication server 158 and the authentication server 140 using the public certificate of the public key infrastructure (PKI).

Here, when the electronic tax invoice information issued for the transaction is in the existing enterprise resource management system 164, the information format related to the tax invoice transmitted from the enterprise resource management system 164 is the XML mapper ( 162 is automatically converted into XML / EDI format and sent to the XML DBMS 162 and stored by the XML DBMS 162.

Subsequently, the control system 156 automatically transmits that the prepared electronic tax invoice is issued to the purchaser's mobile communication terminal 120 through the mobile communication network using the short message service (ST204).

Then, the buyer checks the short message and checks whether the electronic tax invoice is normally issued through his mobile communication terminal or computer terminal 120 (ST206).

This is because the purchaser accesses the web site 152 using his mobile terminal 120 and then accesses a screen for processing the tax invoice, and then verifies or decrypts the electronic signature on the encrypted tax invoice. The method is used to verify the stability of the data. Alternatively, the purchaser may directly access and check the web server 152 using a computer terminal.

The digital signature method is performed according to a mutual authentication procedure between the authentication server 158 and the authorized authentication server 140 associated with the XML / EDI system 160, and in general, if authentication is not performed for a predetermined number of times, access is performed. Make it impossible.

Meanwhile, as described above, the purchaser accesses the web server 152 through his mobile terminal or the computer terminal 120 and checks whether the tax invoice in the XML / EDI format is correctly issued. If the electronic tax invoice is normally issued, the approval process is performed (ST210-Yes). If the contents described in the electronic tax invoice are incorrectly written or cannot be confirmed due to an error, the mobile telecommunication terminal 110 of the seller is performed. Deny approval of the electronic tax invoice and request correction (ST212-No).

When the seller's mobile communication terminal 110 receives the correction request from step ST212, the seller returns to the process of rewriting the electronic tax invoice contents by using the mobile communication terminal 110 of the seller. do.

2b is a flowchart illustrating a process of reversely issuing an electronic tax invoice using a mobile according to an embodiment of the present invention.

The reverse issuance method is a service in which a buyer prepares an electronic tax invoice differently from the net issuance method and requests a seller to issue it.

This may be the case where the buyer directly requires the tax invoice before the seller issues the tax invoice after the commerce occurs between the seller and the buyer as described above.

First, when the commerce occurs (ST220), the purchaser prepares an electronic tax invoice for the generated commerce using its mobile communication terminal or computer terminal 120 (ST222). It is created by accessing a web server 152 associated with the control system 152 by operating a mobile communication terminal or a computer terminal 120 and accessing an electronic tax invoice issuing menu, or writing the generated transaction in an XML DBMS. In (166), search, select, and create.

In this case, the electronic tax invoices are stored in the XML DBMS 166 in XML / EDI format in case of direct writing by accessing the web through the terminal 120 or searching and selecting the generated transaction. .

Subsequently, when the electronic tax invoice is prepared and a text message requiring approval is transmitted from the purchaser terminal 120 to the seller's mobile communication terminal 110 via the mobile communication network (ST224) (see FIG. 3A), The seller checks the details described in the electronic tax invoice using his mobile communication terminal 110 according to the request for approval of the electronic tax invoice transmitted (ST226).

In the case where the electronic tax invoice is normally written according to the verification process (ST228-Yes), the seller presses this when the predetermined key provided in his terminal 110, for example, the Arabic numeral '1' is set as the approval key. (See FIG. 3B).

The approval procedure is performed by the control system 156 normally processing the electronic tax invoice when the approval key is operated.

However, if the electronic tax invoice is abnormally described (ST228-No), the seller rejects the approval by pressing a predetermined key provided in the mobile communication terminal 110, for example, if the Arabic numeral '2' is set as the rejection key. And a correction request procedure (see FIG. 3B).

When the approval rejection key is manipulated, the corresponding message is transmitted to the purchaser's terminal 120, and the buyer rewrites the electronic tax invoice and repeats the procedure requiring issuance approval as described above (step 222). comeback).

As described above, according to the electronic tax invoice issuance system of the present invention, when a tax invoice is required to be issued according to a predetermined commerce occurrence, the seller prepares and issues a tax invoice using a mobile device such as a mobile communication terminal, and the purchaser purchases a mobile device. You can check this directly or by accessing the website through a computer terminal.On the contrary, when a buyer completes a tax invoice through a mobile device or computer terminal and sends it to the seller, the seller confirms the tax invoice through the mobile terminal. By approving and approving, the tax invoice can be issued in real time without any space restrictions.

In addition, it is possible to issue a secure electronic tax invoice because encryption and digital signature authentication procedures are provided in XML / EDI format in connection with XML DBMS and enterprise resource management system.

On the other hand, the present invention is not limited to the above-described specific preferred embodiments, and various changes can be made by those skilled in the art without departing from the gist of the invention claimed in the claims. will be.
