The security unit 110 may provide thorough security to a database (DB) in which data necessary for the accounting service is stored, as will be described later.

FIG. 2 is a diagram illustrating an accounting starter server according to an embodiment of the present invention.

2, the accounting captain server 100 includes an SNS communication unit 101, a voice recognition unit 102, a scrap unit 103, a data processing unit 104, a tax accounting processing unit 105, A foreign exchange processing unit 106, a foreign exchange processing unit 107, and a control unit 108.

The SNS communication unit 101 communicates with the business entity terminal 200 and the tax agent terminal 300 in cooperation with the SNS server 400 through the network and transmits data transmitted from the business entity terminal 200 and the tax agent terminal 300 And transmits the information processed by the accounting captainer server 100 to the business terminal 200 and the tax agent terminal 300 so that the information is displayed on the display unit of each terminal.

The SNS communication unit 101 receives the user ID of the SNS server 400 through the OAuth authentication method of the SNS provided by the SNS server 400, Service becomes available. This also applies to the tax agent terminal 300.

The voice recognition unit 102 may automatically convert the transaction history voice information received from the business entity terminal 100 into transaction history text information and store the transaction history text information in a DB for each business entity terminal account. That is, the speech recognition unit 102 can recognize the speech signal in the transaction history voice information and generate character string information composed of text. Here, the transaction history voice information includes transaction date, supplier name, transaction content, purchase revenue identification information (transaction classification information), payment means identification information (cash, card, etc.), purchase purchase cost (supply price, can do. As an example of speech recognition technology, it is possible to utilize an API in the form of STT (Speech To Text) disclosed by Google or the following. The voice recognition unit 102 transmits the character string information generated based on the voice signal to the data processing unit 104.

The scrap unit 103 scrapes the transaction details of the business entity terminal from the financial institution server (not shown) based on the business name, the business registration number, the main transaction card number and the main account account number provided by the business entity terminal 100 can do. At this time, the control unit 108 may check the validity of the transaction history text information acquired by the speech recognition unit 102 based on transaction details scrapped by the scrap unit 103. [

The data processor 104 may process the converted transaction history text information and / or scrapped transaction details into tax accounting data and store the processed tax accounting data in a database (DB) for each business terminal account.

The tax accounting processing unit 105 performs the tax accounting period based on the tax accounting data processed by the data processing unit 104. [ Here, the tax accountant may be performed by the tax agent terminal 300 through the accounting captain program.

The simple book creating unit 106 creates a simple book containing a predetermined list or containing only a list desired by the business operator. The generated simple book can be quickly transferred to the account of the provider terminal 200 using the SNS.

FIGS. 3 and 4 are views showing examples of simple books according to an embodiment of the present invention.

Referring to FIG. 4, the simple book is generated based on recent input transactions, and includes a transaction date, a transaction classification, a customer, a transaction content, a supply price, and a tax amount as a list.

In addition, referring to FIG. 5, it can be seen that a simple account for the card sales / deposit history is generated from the tax accounting data, and the sales amount, the deposit amount, and the estimated deposit amount are displayed in different colors.

In addition, when the tax accounting processing data includes the foreign exchange information, the service server can convert the corresponding foreign exchange information into the Korean currency through the foreign exchange processing unit 17 and reflect it in the tax accounting processing data.

That is, when the tax accounting data includes the foreign exchange information, the foreign exchange processing unit 107 converts the foreign exchange information into foreign exchange information of the first and second foreign currencies. Preferably, the foreign currency processing unit 107 can perform foreign currency conversion by applying the foreign currency exchange rate based on the receipt date, that is, based on the sales entry point.

For example, on April 1, 20xx, the company sold 80,000 won worth of merchandise overseas and earned $ 100 in foreign currency sales. The exchange rate per dollar for each point was 1,000 won on March 31, 20xx, and April 1, The foreign exchange processing unit 107 applies the foreign exchange rate at the foreign exchange rate based on the foreign exchange rate of April 1, 20xx, which is the date of receipt, The conversion rate can be reflected. Furthermore, since it is difficult for operators to easily convert the value of goods into their mental arithmetic, this function can intuitively and conveniently allow the operator to understand how much sales are made.

In another embodiment, when the tax accounting processing data includes foreign exchange information and the purchase revenue identification information is 'purchase', the foreign exchange processing unit 107 may convert the sales cost of the first currency into a second currency To provide information and to settle the second call. At this time, the second currency can be determined as the currency having the lowest real-time exchange rate, that is, the lowest real-time value, compared with the pre-stored reference exchange rate. For example, if there is a currency exchange rate of $ 1 = 100 and a currency exchange rate of $ 1 = 10,000, the payer would prefer the currency with the lowest real-time value to be the second currency.

The first call and the second call are distinguished from each other only for the sake of identification, and the first call and the second call are not necessarily the same, but may be different from each other. When the first call and the second call are different, for example, the first call and the second call are all charged in the case of a non-major currency (pound, franc, etc.) rather than a major currency (dollar, Can be set higher. If desired, it may be possible for the user to select a currency type.

Also, the foreign exchange processing unit 107 selects any one of the plurality of payment means to perform settlement. The plurality of payment means may include a first payment means and a second payment means. The first payment means may settle the first call. The second payment means may settle the second call different from the first call. It can be done. Here, the payment means may be a bank account or a credit card, and may include various payment solutions such as Samsung Pay and Naver Pay.

The control unit 18 controls functions and operations of the respective components.

5 and 6 are views for explaining the security operation of the security unit of FIG.

5, the security unit may store the transaction history text information and the tax accounting processing data in the DB after the matrix encryption processing.

The matrix encryption process divides the received character string into four character strings to generate four character strings.

Next, in the conversion step, the four character strings are arranged in order from the first row to the fourth row, and converted into a 4X4 matrix. For example, when the received character string is "sagedatabestcomp ", in the conversion step," sagedatabestcomp "is divided into four character strings and four four character strings, i.e., " sage "," data ", " comp ". According to the embodiment, when the number of characters in the received character string does not reach 16, the number of characters in the character string can be reduced to 16 by inserting special characters (#, *, /, or?

Next, in the rearrangement step, the character strings belonging to the i-th (i is a natural number) row in the 4x4 matrix are rearranged into the i-th column.

In the figure, the first matrix M1 means a matrix before rearrangement, and the second matrix M2 means a matrix after rearrangement. In the rearrangement step, the character string (e.g., "sage") belonging to the first row in the first matrix M1 is rearranged from the second matrix M2 to the first column (e.g., "sage & (E.g., "data") belonging to the second row in the matrix M1 is rearranged from the second matrix M2 to the second column (e.g., "data").

Next, in the replacement step, each element in the rearranged 4X4 matrix is replaced with another element. The step of replacing each element with another element in the rearranged 4X4 matrix may be performed by the following equation.

[Equation 1]

a [j] '= ((s1 + a [j]) Mod 26 + s2 Mod 26

Where a [j] represents a character sequence value of each element in the rearranged 4x4 matrix, a [j] 'represents a character sequence value of each element in the replaced 4x4 matrix after being replaced, j is a natural number, s1 is a first cryptographic key, s2 is a second cryptographic key, and Mod is a function for obtaining a remainder value, wherein s1 is a first cryptographic matrix of 4X4 composed of 16 random numbers, Th row) of the first row corresponds to the j-th element value in a state in which the random numbers belonging to the i-th row are rearranged to the k-th column, and s2 corresponds to the second element of 4x4 composed of 16 random numbers that differ from the random numbers by at least one And corresponds to the j-th element value in a state where the random numbers belonging to the (l is a natural number) row of the encryption matrix are rearranged in the lth column.

The encryption keys s1 and s2 are generated as random numbers. According to the embodiment, the cipher keys s1 and s2 can be rearranged into respective columns for security enhancement. In the figure, the matrices S1 and S2 represent cryptographic key values generated by random numbers.

When the i is 1, the character of a [1] in the second matrix M2 is 's'. When the i is 16, the letter of a [16] in the second matrix M2 is 'm'. When the letter 'a' is the zeroth in alphabetical order, the letter 's' is the 18th alphabetical order. The number in the matrix S1 of the first cryptographic key s1 corresponding to a [1] in the second matrix M2 is '1'. the number is '1' in the matrix S2 of the second cryptographic key s2 corresponding to a [1]. The number in the matrix S1 of the first cryptographic key s1 corresponding to a [16] in the second matrix M2 is '0'. The number in the matrix S2 of the second cryptographic key s2 corresponding to a [16] in the second matrix M2 is '5'.

The value of a [1] of the first element 's' in the second matrix M2 is 18 and the value of the matrix S1 of the first cryptographic key s1 corresponding to a [1] in the second matrix M2 is 18, , The sum of the two numbers is (18 + 1) = 19. 19 is divided by 26 is 7, and the number is 1 in the matrix S2 of the second cryptographic key s2 corresponding to a [1], so that the sum of the two numbers is (7 + 1) = 8. The remainder of dividing 8 by 26 is 2. Therefore a [1] '= 2. When the letter 'a' is the zeroth in alphabetical order, the second alphabetic character is 'c'. The replacement module 15 therefore replaces the first element, the letter 's', in the second matrix M2 with the other element 'c' in the third matrix M3. Since the number of alphabets is 26, the remaining value is obtained by dividing by 26. However, in the case of a number or a special character, another number may be used instead of the number 26.

On the other hand, most of the DB encryption methods are installed in the DB by applying the software method, and the efficiency of the DB server is decreased because the performance of the DB server is significantly lowered at the time of operation. When the DB encryption function is applied and the encryption function is not applied, the performance is degraded by several times to several tens of times.

According to the present invention, as another embodiment, the security unit provides a thorough security to the database by the data masking technique.

Referring to FIG. 6, the security unit stores the transaction history text information and the tax accounting processing data in the database (DB) after the masking process.

① The administrator sets a data masking policy to protect the important data from the user in the data masking server.

② The user requests the query to the DB server through the data masking server.

③ The data masking server sends the user query to the DB server.

④ The DB server sends the result to the data masking server.

⑤ The data masking server compares the data masking policy setting with the server response value and masks the data with special characters (for example, '*' (asterisk)) when data masking is required.

Here, the data masking technique includes a data masking technique based on a regular expression expression in which a regular expression is set and masking processing is performed when the regular response expression of the server response string value matches the corresponding regular expression, and a masking process is performed on the table and the column specified by the administrator A data masking technique based on table and column designation can be used.

(6) The data masking result value is transmitted to the user, and the user receives the result value in which some of the server response values are masked.

Specifically, the user requests a user command through the data masking server to the DBMS. At this time, the data masking server extracts and analyzes the form and basic information of the user command.

Next, based on the analyzed data and the data masking policy of the basic data, the table, column and row information to be subjected to data masking are analyzed and extracted.

Next, the extracted data masking target table, column, and row information are analyzed according to the data masking policy for the set regular expression. If the masking policy is met, the information is masked.

The advantage of this data masking technique is that the user and the DB server do not have to install or change the settings of a separate program, thus ensuring high availability and the user can select and use the application program according to the business need without any limitation of the application program, It is equally applicable to systems with different environments.

This data masking technique, which is a centralized method by the data masking server, not only improves the method of collecting relevant information (logs and the like), but also manages and manages the data, but also has a dedicated client as in the existing data masking technique It is possible to protect important data by data masking even when using non-exclusive client tool.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. This is possible. Therefore, the scope of the present invention should not be construed as being limited to the embodiments described, but should be determined by the scope of the appended claims, as well as the appended claims.
