Referring to FIG. 1 , an electronic device 110 according to the present invention includes a list generator 111 and a storage unit 112 .

When a tree structure listing command for a table inserted into an electronic document (the table is composed of a plurality of fields and data is inserted for each field) is received from the user, the list creation unit 111 By subordinating the lower data inserted into the n+1 (n is a natural number of 1 or more) field on the table to the upper data corresponding to each lower data among the upper data inserted into the n-th field, each of the plurality of fields Creates a tree structure list of inserted data.

For example, when it is assumed that a table composed of a plurality of fields 211, 212, and 213 as shown in FIG. 2 is inserted into the electronic document, the list generator 111 selects the n+1th field on the table. By subordinating the lower data inserted in to the upper data corresponding to each lower data among the upper data inserted in the n-th field, each of the plurality of fields 211, 212, and 213 as shown in FIG. You can create a tree structure list of inserted data.

In relation to this, the list generator 111 converts 'mackerel' and 'saury', which are lower data inserted into a field called 'thing' (212), into 'mackerel' among upper data inserted into a field called 'classification' (211). ', 'saury' can be subordinated to 'fish', which is the upper data corresponding to 'thing' (212), and 'pigeon' and 'sparrow', which are lower data inserted into the field called 'thing' (212), are called 'class' (211). Among the upper data inserted into the field, it can be subordinated to 'bird', which is the upper data corresponding to 'pigeon' and 'sparrow', and the lower data inserted into the field 'thing' (212), 'whale', ' 'Rabbit' may be subordinated to 'mammal', which is upper data corresponding to 'whale' and 'rabbit' among upper data inserted into the field 'classification' 211 .

In this way, the list generator 111 converts the lower data inserted into the field 'description' 213 to the upper data corresponding to each lower data among the upper data inserted into the field 'thing' 212. can be subordinated.

In this way, the list creation unit 111 may generate a tree structure list as shown in FIG. 3 by subordinating lower data existing in the n+1 th field to corresponding upper data in the n th field.

When the tree structure list is generated, the storage unit 112 creates a list file composed of data for the tree structure list and then stores the list file in the file storage 113 .

In this case, according to an embodiment of the present invention, the electronic device 110 may further include an outline document display unit 114 .

After the list file is stored in the file storage 113, the outline document display unit 114 reads the data for the tree structure list when an open command for the list file is received from the user, and An outline document in which upper data and lower data corresponding to each upper data are sequentially listed and displayed from top to bottom is generated, and then the outline document is displayed on the screen.

In this regard, when it is assumed that a list file consisting of data for a tree structure list as shown in FIG. 3 is stored in the file storage 113, the outline document display unit 114 receives an open command of the list file from the user. is received, the data for the tree structure list is read, and as shown in FIG. 4, upper data and lower data corresponding to each upper data in the tree structure list are sequentially listed from top to bottom. After generating the displayed outline document, the outline document may be displayed on the screen.

In this regard, the outline document display unit 114 displays data in the order of fields of 'classification' 211, 'object' 212, and 'description' 213 from top to bottom, as shown in the figure shown in FIG. After creating an overview document that is sequentially listed and displayed, it can be displayed on the screen.

Through this, the user can view the overview document and easily grasp the upper-lower relationship of data for each field.

At this time, according to an embodiment of the present invention, the electronic device 110 may further include a list correction unit 115 .

The list modifying unit 115 responds to the change of the first data when the user changes the first data, which is any one data existing on the outline document, after the outline document is displayed on the screen. After modifying the tree-structured list by changing the first data existing on the tree-structured list, the list file is regenerated based on the data for the tree-structured list and stored again in the file storage 113. can be saved

For example, when it is assumed that an overview document such as the picture shown in FIG. 4 is displayed on the screen, and that the user changes 'saury' to 'hairtail' among the data existing on the overview document, the list correction unit ( 115) corrects the tree structure list by changing 'saury' to 'hairfish' on the tree structure list shown in FIG. The file can be recreated and saved back to the file store 113.

According to one embodiment of the present invention, the electronic device 110 is configured to enable security settings for the list file, and includes a table maintenance unit 116, a random number generator 117, and an encryption key extraction unit 118. ), a file encryption unit 119 and a guide message display unit 120 may be further included.

The table maintenance unit 116 stores and maintains a table in which predetermined t (t is a natural number of 2 or more) encryption keys and integers of 0 or more and t-1 or less corresponding to each encryption key are recorded.

For example, assuming that t is '5', the table maintenance unit 116 may store and maintain an encryption key table such as Table 1 below.

5 encryption keys integer value encryption key 1 0 encryption key 2 One encryption key 3 2 encryption key 4 3 encryption key 5 4

After the list file is stored in the file storage 113, the random number generator 117 generates a random number of k (k is a natural number of 3 or more) digits when a security setting command for the list file is received from the user.

For example, when k is 3, the random number generator 117 may generate a random number such as '221' as a 3-digit random number.

When the random number is generated, the encryption key extraction unit 118 calculates an operation value by performing a modulo operation with the random number as the dividend and the t as the divisor, and corresponding to the operation value from the table A first encryption key is extracted.

Here, the modulo operation refers to an operation of calculating a remainder by performing division by dividing a dividend by a divisor.

For example, as in the above example, when it is assumed that t is '5' and the random number is '221', the encryption key extraction unit 118 takes the random number '221' as the dividend and sets the '5' By performing a modulo operation as a divisor, the operation value may be calculated as '1'.

Then, the encryption key extraction unit 118 may extract 'encryption key 2' as the first encryption key corresponding to the operation value '1' from the table such as Table 1 above.

The file encryption unit 119 encrypts the list file with the first encryption key.

For example, as in the above example, when 'encryption key 2' is extracted as the first encryption key through the encryption key extraction unit 118, the file encryption unit 119 converts the list file to the first encryption key ' It can be encrypted with encryption key 2'.

When the list file is encrypted, the guide message display unit 120 displays a guide message indicating that the random number is a security code for decryption of the list file on the screen.

At this time, the user may read the guide message and be familiar with the security code displayed on the screen in order to perform decryption of the list file later.

At this time, according to an embodiment of the present invention, the electronic device 110 may further include a security code input message display unit 121 and a decryption unit 122.

The security code input message display unit 121 inputs a security code instructing the user to input the security code for security release when a security release command of the list file is received from the user after the encryption of the list file is completed. A message is displayed on the screen.

For example, when a command to release the security of the list file is received from the user, the security code input message display unit 121 may display a security code input window on the screen along with a security code input message saying 'Please enter a security code'. there is.

At this time, when the random number is input to the electronic device 110 in response to the security code input message from the user, the decoder 122 performs a modulo operation with the random number as the dividend and the divisor with t, , After calculating the calculation value, extracting the first encryption key corresponding to the calculation value from the table, and then decrypting the list file with the first encryption key.

For example, as in the above example, when it is assumed that t is '5' and the random number is '221', the decoder 122 receives the random number '221' from the user as a security code. An operation value of '1' may be calculated by performing a modulo operation with the random number '221' as the dividend and '5' as the divisor.

Then, the decryption unit 122 extracts 'encryption key 2' as the first encryption key corresponding to the operation value '1' from the table such as Table 1, and then decrypts the list file with 'encryption key 2'. can do.
