<Processing Operation of Document Management Apparatus 1>
Next, the processing operation of the document management apparatus 1 of this embodiment will be described.

<How to create a hierarchy / user ID correspondence table>
First, a method for creating a hierarchy / user ID correspondence table will be described with reference to FIGS. FIG. 3 is a flowchart for explaining a method of creating a hierarchy / user ID correspondence table.

  First, the input unit 13 inputs the number of hierarchies (N) of the access level to the hierarchy / user ID correspondence table storage unit 14 (step S1). The tier / user ID correspondence table storage unit 14 secures tier tables for the number of tiers (N) input from the input unit 13 (step S2). In this case, as shown in FIG. 2, the hierarchy / user ID table storage unit 14 sets the hierarchy table with the lowest access level to 1, and sets the hierarchy table with the highest access level to N ( Step S3).

  Next, the input unit 13 inputs the user ID and the access level (hierarchy) of the user ID to the hierarchy / user ID correspondence table storage unit 14 (step S4). The hierarchy / user ID correspondence table storage unit 14 sets the user ID in the hierarchy table of the access level (hierarchy) input from the input unit 13 (step S5).

  Next, the hierarchy / user ID correspondence table storage unit 14 determines whether or not all user IDs input from the input unit 13 have been set in the hierarchy table (step S6). When all user IDs input from the input unit 13 are set in the hierarchy table (step S6 / Yes), the hierarchy / user ID correspondence table storage unit 14 converts the hierarchy table into the hierarchy / user ID correspondence table. Is stored in the hierarchy / user ID correspondence table storage unit 14 (step S7), and the process is terminated.

  As a result, the hierarchy / user ID correspondence table storage unit 14 creates the hierarchy / user ID correspondence table shown in FIG. 2, and uses the created hierarchy / user ID correspondence table as the hierarchy / user ID correspondence table storage unit. 14 will be saved and managed. Note that the creation method of the hierarchy / user ID correspondence table shown in FIG. 2 is not limited to the above-described method, and any creation method can be applied.

<How to create a document correspondence hierarchy table>
Next, a method for creating a document correspondence hierarchy table will be described with reference to FIGS. FIG. 4 is a flowchart for explaining a method for creating a document correspondence hierarchy table, and FIG. 5 is an explanatory schematic diagram thereof.

  First, the input unit 13 reads a document and creates an electronic document (step A1). As a result, the electronic document shown in FIG. 5A is obtained. Next, the document correspondence hierarchy table creation unit 15 counts the number of characters (M) of the electronic document shown in FIG. 5A (step A2), and secures a hierarchy table for the counted number of characters (M) (step S2). A3). As a result, the document correspondence hierarchy table shown in FIG. 5B is created.

  Next, the document correspondence hierarchy table creation unit 15 sets all areas of the document correspondence hierarchy table shown in FIG. 5B created in step A3 to default 1 (the lowest hierarchy) (step A4). As a result, the document correspondence hierarchy table in the default state shown in FIG. 5C is created. Further, the document correspondence hierarchy table creation unit 15 stores the electronic document shown in FIG. 5A in the document storage unit 12. In the example of FIG. 5, the electronic document is divided into a plurality of segments (M) in character units, and a hierarchy is set for each segment (M). However, the unit divided into segments is not limited to character units, and can be constructed so as to be divided into chapters, paragraphs, sentences, and words.

<Setting method of document correspondence hierarchy table>
Next, a method for setting the document correspondence hierarchy table will be described with reference to FIGS. FIG. 6 is a flowchart for explaining a method for setting a document correspondence hierarchy table, and FIG. 7 is an explanatory schematic diagram thereof.

  First, the document correspondence hierarchy table creation unit 15 determines whether or not to perform hierarchy division (step B1). The document-corresponding hierarchy table creating unit 15 starts the hierarchical character division M ′ (where 1 ≦ M ′ ≦ M) and the hierarchy N ′ (where 1 ≦ N ′ ≦) that is set to the starting character position M ′. When N is input from the input unit 13, it is determined that the hierarchy is to be performed (step B1 / Yes), and the start character position M ′ and the hierarchy N ′ are set in the document correspondence hierarchy table ( In this case, the document correspondence layer table creation unit 15 sets all layers of character positions M ′ + 1 to M after the start character position M ′ to N ′ (step B4).

  The document correspondence hierarchy table creation unit 15 performs the above-described series of processing of Steps B1 to B4 until there is no place to divide the hierarchy, and when it is determined that the hierarchy division is finished (Step B5 / Yes), the document correspondence hierarchy table Is stored in the document correspondence hierarchy table storage unit 16 (step B6), and the process ends. As a result, the document correspondence hierarchy table creation unit 15 saves the document correspondence hierarchy table shown in FIG. 7B in the document correspondence hierarchy table storage unit 16.

  The document correspondence hierarchy table creating unit 15 includes the electronic document shown in FIG. 5A stored in the document storage unit 12 and the document correspondence hierarchy table shown in FIG. 7B stored in the document correspondence hierarchy table storage unit 16. Are assigned the same document ID, and the electronic document shown in FIG. 5A and the document correspondence hierarchy table shown in FIG. 7B are managed in association with each other.

<Output processing of electronic document corresponding to user ID>
Next, an electronic document output process corresponding to the user ID will be described with reference to FIGS. FIG. 8 is a flowchart for explaining the output processing of the electronic document, FIG. 9 is a flowchart for explaining the processing 1 shown in FIG. 8, and FIG. 10 is an explanatory schematic diagram of FIGS. It is.

  First, the user inputs a user ID from the user terminal device 2, logs in after receiving authentication (step C1). Next, the user inputs a document name to be browsed from the user terminal device 2 (step C2).

  The document output unit 17 reads out the corresponding electronic document from the document storage unit 12 based on the document name input from the user terminal device 2 (step C3). Further, the document output unit 17 reads out the document correspondence hierarchy table corresponding to the corresponding electronic document from the document correspondence hierarchy table storage unit 16 (step C4).

  For example, assume that the document name input from the user terminal device 2 is the document “Hiragana” shown in FIG. In this case, the document output unit 17 reads the document correspondence hierarchy table corresponding to the document “Hiragana” from the document correspondence hierarchy table storage unit 16 as shown in FIG.

  Next, the document output unit 17 sets 1 (lowest hierarchy) in the register R1 (step C5), and determines whether or not a user ID is registered in the hierarchy set in the register R1 (step C6). If the user ID is not registered in the hierarchy set in the register R1 (step C6 / No), the document output unit 17 adds one hierarchy set in the register R1 (R1 = R1 + 1) (step C7 ). Then, it is determined whether or not the hierarchy set in the register R1 is greater than N (the highest hierarchy) (step C8). If the hierarchy set in the register R1 is greater than N (the highest hierarchy) (step C8 / Yes), it is determined that the user ID input from the user terminal device 2 is not registered in the hierarchy / user ID correspondence table storage unit 14 (no user ID), and the process ends.

  In addition, when the user ID is registered in the hierarchy set in the register R1 (Step C6 / Yes), the document output unit 17 determines that the user ID input from the user terminal device 2 is the hierarchy / user. It is determined that it is registered in the ID correspondence table storage unit 14, and processing 1 shown in FIG. 9 described later is started (step C9). Then, the document output unit 17 outputs the electronic document subjected to the processing 1 to the user terminal device 2 (Step C10), and ends the processing.

<Detailed operation of processing 1>
Next, the detailed operation of the process 1 in step C9 shown in FIG. 8 will be described with reference to FIG.

  First, the document output unit 17 sets 1 in the register R2 (step D1). The register R2 indicates the character position in the document correspondence hierarchy table shown in FIG. In this case, the first character position in the document correspondence hierarchy table; 1 is indicated. Next, the document output unit 17 sets a hierarchy usable by the user in the register R3 (step D2). For example, it is assumed that the user ID input from the user terminal device 2 is ID A003 shown in FIG. In this case, the document output unit 17 uses the user ID; A 003 shown in FIG. 10A input from the user terminal device 2 as shown in FIG. Hierarchy available to the user 003; 2 is read from the hierarchy / user ID correspondence table storage unit 14, and the hierarchy; 2 is set in the register R3.

  Next, the document output unit 17 determines whether or not the hierarchy of the character position set in the register R2 is higher than the hierarchy set in the register R3 (step D3). If the character position set in the register R2 is higher than the set in the register R3 (step D3 / Yes), the document output unit 17 converts the electronic document at the character position set in the register R2 into a hidden character (step D4). ). Thus, the document output unit 17 can make the electronic document in a character position that is not permitted to be browsed into a format that cannot be browsed by the user. The processing performed on the electronic document at the character position where browsing is not permitted is not particularly limited as long as it can be converted into a format that cannot be viewed by the user. For example, character conversion processing or mosaic processing is not limited. Etc. are applicable.

  In addition, when the hierarchy of the character position set in the register R2 is not larger than the hierarchy set in the register R3 (step D3 / No), the document output unit 17 keeps the electronic document at the character position set in the register R2 as it is. Format. As a result, the document output unit 17 can keep the electronic document at the character position permitted to be browsed in a browsable format.

  Next, the document output unit 17 determines whether or not the character position set in the register R2 is the last character of the electronic document (step D5). If it is not the last character (step D5 / No), the character output is set in the register R2. The selected character position is shifted by one (R2 = R2 + 1) (step D6). Then, the processes in steps D3 to D6 are repeated until the character position set in the register R2 becomes the last character. When the character position becomes the last character (step D5 / Yes), the process is terminated.

  For example, based on the user ID; A003 shown in FIG. 10A input from the user terminal device 2, as shown in FIG. 10C, the user with the user ID; A003 can use it. 2 is read from the hierarchy / user ID correspondence table storage unit 14, and the hierarchy; 2 is set in the register R3. In this case, the document output unit 17 converts the electronic document at the character position in the hierarchy set in the register R3; the hierarchy higher than 2 in the document correspondence hierarchy table shown in FIG. As a result, the document output unit 17 converts the electronic document at the character position higher than 2 in the document correspondence hierarchy table shown in FIG. The electronic document shown in d) is generated and output to the user terminal device 2.

<Operation / Effect of Document Management System of Present Embodiment>
As described above, the document management apparatus 1 of the document management system according to the present embodiment associates the user ID for identifying the user with the access right (hierarchy) for permitting browsing of the electronic document. The hierarchy / user ID correspondence table shown in FIG. 2 is created and stored in the hierarchy / user ID correspondence table storage unit 14.

  Further, the document management apparatus 1 divides one electronic document into a plurality of segments, sets an access right (hierarchy) for permitting browsing for each segment, and creates a document correspondence hierarchy table shown in FIG. It is created and stored in the document correspondence hierarchy table storage unit 16.

  Then, based on the document name shown in FIG. 10 (a) input from the user terminal device 2, the document management apparatus 1 reads out the electronic document with the corresponding document name from the document storage unit 12, and the corresponding document name. The document correspondence hierarchy table shown in FIG. 10B corresponding to the electronic document is read from the document correspondence hierarchy table storage unit 16. Further, based on the user ID shown in FIG. 10B input from the user terminal device 2, the hierarchy (access right) shown in FIG. Read from the user ID correspondence table storage unit 14. Then, the hierarchy (access right) of the user ID read from the hierarchy / user ID correspondence table storage unit 14 and the document correspondence hierarchy table shown in FIG. Based on the user ID hierarchy, the segment with a value set below the user ID hierarchy can be viewed, and the segment with a value greater than the user ID hierarchy cannot be viewed. The electronic document shown in FIG. 10 (d) is created, and the created electronic document shown in FIG. 10 (d) is output to the user terminal device 2 to be viewed by the user.

  As a result, the document management apparatus 1 according to the present embodiment divides one electronic document into a plurality of segments, and the document correspondence hierarchy table shown in FIG. 10B in which the access right (hierarchy) is set for each segment. Will be created. Then, the document correspondence hierarchy table shown in FIG. 10 (b) in which the access right (hierarchy) is set for each segment, and the hierarchy shown in FIG. 10 (c) in which the access right (hierarchy) is set for each user. Based on the user ID correspondence table, the electronic document shown in FIG. 10 (d) in a format that can be viewed with the access right (hierarchy) set for each user is generated, and the generated FIG. 10 (d) It is possible to allow the user to browse the electronic document shown in FIG.

(Second Embodiment)
Next, a second embodiment will be described.

  In the first embodiment, based on the document correspondence hierarchy table shown in FIG. 10B and the hierarchy / user ID correspondence table shown in FIG. 10C, the access right ( The electronic document shown in FIG. 10 (d) in a format that can be browsed in a hierarchy) is generated, and the user is allowed to browse the generated electronic document shown in FIG. 10 (d).

  In the second embodiment, based on the document correspondence hierarchy table shown in FIG. 12B, the document file shown in FIG. 12C that can be viewed with each access right (hierarchy) is displayed for each access right (hierarchy). Create and save in the document storage unit 12. Then, the document file for each access right (hierarchy) shown in FIG. 14 (c) stored in the document storage unit 12 and the hierarchy / file shown in FIG. 14 (b) in which the access right (hierarchy) is set for each user. Based on the user ID correspondence table, a document file that can be viewed with the access right (hierarchy) set for each user is acquired from the document storage unit 12 shown in FIG. 14C, and the acquired FIG. The user browses the electronic document of the document file shown in (d). As a result, a document file for each access right (hierarchy) is stored in the document storage unit 12 in advance, and the electronic document of the document file is browsed by the user, so that the user can quickly browse the electronic document. It becomes possible. Hereinafter, a second embodiment will be described with reference to the accompanying drawings. Note that the system configuration of the document management system of the second embodiment is the same as that of the first embodiment, and only the processing operations performed by the document management device 1 are different. Only explained.

<How to create a hierarchy / user ID correspondence table>
The method for creating the hierarchy / user ID correspondence table is created in the same manner as in the first embodiment shown in FIG.

<How to create a document correspondence hierarchy table>
The document correspondence hierarchy table is created in the same manner as in the first embodiment shown in FIGS.

<How to create document files for each layer>
Next, a document file creation method for each hierarchy will be described with reference to FIGS. 11 and 12. FIG. 11 is a flowchart for explaining a document file creation method for each layer, and FIG. 12 is a schematic diagram for explaining the method.

  First, the document correspondence hierarchy table creation unit 15 determines whether or not to perform hierarchy division (step B1). The document-corresponding hierarchy table creating unit 15 starts the hierarchical character division M ′ (where 1 ≦ M ′ ≦ M) and the hierarchical character N ′ (where 1 ≦ N ′ ≦) that is designated as the starting character position M ′. When N is input from the input unit 13, it is determined that the hierarchy is to be performed (step B1 / Yes), and the start character position M ′ and the hierarchy N ′ are set in the document correspondence hierarchy table ( Steps B2 and B3) In this case, the document correspondence hierarchy table creation unit 15 sets all the levels of character positions M after the start character position M ′ to N ′ (step B4). When the series of processes in steps B1 to B4 described above are performed until there is no place to perform hierarchy division, and it is determined that hierarchy division is complete (step B5 / Yes), the document correspondence hierarchy table is stored in the document correspondence hierarchy table storage unit 16. (Step B6), whereby the document correspondence hierarchical table shown in FIG. Will save Le in the document corresponding hierarchical table storage unit 16.

  Next, the document correspondence hierarchy table creation unit 15 sets hierarchy 1 in the register R1 (step B'7) and sets character position 1 in the register R2 in order to create a document file for each hierarchy (step B). '8). The register R1 indicates the hierarchy of the electronic document, and the register R2 indicates the character position in the document correspondence hierarchy table shown in FIG.

  Next, the document correspondence hierarchy table creating unit 15 determines whether or not the hierarchy of the character position set in the register R2 is larger than the hierarchy set in the register R1 (step B'9), and the character position set in the register R2 Is higher than the level set in the register R1 (step B'9 / Yes), the electronic document at the character position set in the register R2 is converted into a syllabary (step B'10). As a result, the document correspondence hierarchy table creating unit 15 can make the electronic document in a character position larger than the hierarchy set in the register R1 into a format that cannot be viewed.

  In addition, when the hierarchy of the character position set in the register R2 is not larger than the hierarchy set in the register R1 (step D3 / No), the document correspondence hierarchy table creating unit 15 performs the electronic document at the character position set in the register R2. In the same format. As a result, the document correspondence hierarchy table creating unit 15 can keep the electronic document in the character position not larger than the hierarchy set in the register R1 in a viewable format.

  Next, the document correspondence hierarchy table creating unit 15 determines whether or not the character position set in the register R2 is the last character of the electronic document (step B′11). When the character position set in the register R2 is not the last character (step B'11 / No), the document correspondence hierarchy table creation unit 15 shifts the character position set in the register R2 by one (R2 = R2 + 1) (step B′12), the processes of steps B′9 to B′12 are repeated until the character position set in the register R2 becomes the final character. Then, when the character position set in the register R2 becomes the last character (step B'11 / Yes), the document correspondence hierarchy table creation unit 15 converts the document storage unit 12 as a document file for the hierarchy set in the register R1. (Step B'13).

  Next, the document correspondence hierarchy table creating unit 15 determines whether or not the hierarchy set in the register R1 is the highest hierarchy N (step B′14). If the hierarchy set in the register R1 is not the highest hierarchy N (step B'14 / No), the document correspondence hierarchy table creation unit 15 adds 1 to the hierarchy set in the register R1 (R1 = R1 + 1) (step B′15), a document file for the new hierarchy set in the register R1 is created and stored in the document storage unit 12 (steps B′8 to B′13). Then, when the hierarchy set in the register R1 is the highest hierarchy N (step B′14 / Yes), the document correspondence hierarchy table creation unit 15 ends the process.

  For example, the document correspondence hierarchy table shown in FIG. In this case, the document correspondence hierarchy table creation unit 15 creates a document file for each hierarchy shown in FIG. The document file at level 1 shown in FIG. 12C converts the electronic document at a character position higher than 1 into a hidden character so that only the electronic document at a character position not higher than 1 can be viewed. . In addition, the document file at level 2 shown in FIG. 12C converts an electronic document with a character position higher than 2 into a hidden character so that only an electronic document with a character position not higher than 2 can be viewed. ing. In addition, the document file of level 3 shown in FIG. 12C converts an electronic document with a character position higher than 3 into a hidden character so that only an electronic document with a character position not higher than 3 can be viewed. ing.

<Output processing of electronic document corresponding to user ID>
Next, an electronic document output process corresponding to the user ID will be described with reference to FIGS. FIG. 13 is a flowchart for explaining an electronic document output method, and FIG. 14 is a schematic diagram for explaining the method.

  First, the user inputs a user ID from the user terminal device 2, logs in after receiving authentication (step C1). Next, the user inputs a document name to be browsed from the user terminal device 2 (step C2).

  Next, based on the user ID input from the user terminal device 2, the document output unit 17 reads out a hierarchy that can be used by the user with the user ID from the hierarchy / user ID correspondence table storage unit 14.

  Next, the document output unit 17 sets 1 (lowest hierarchy) in the register R1 (step C5), and determines whether or not a user ID is registered in the hierarchy set in the register R1 (step C6). If the user ID is not registered in the hierarchy set in the register R1 (step C6 / No), the document output unit 17 adds one hierarchy set in the register R1 (R1 = R1 + 1) (step C7 ). Then, it is determined whether or not the hierarchy set in the register R1 is greater than N (the highest hierarchy) (step C8). If the hierarchy set in the register R1 is greater than N (the highest hierarchy) (step C8 / Yes), it is determined that the user ID input from the user terminal device 2 is not registered in the hierarchy / user ID correspondence table storage unit 14 (no user ID), and the process ends.

  If the user ID is registered in the hierarchy set in the register R1 (step C6 / Yes), the document output unit 17 stores the document name input from the user terminal device 2 and the user ID. Based on the registered hierarchy, the document file corresponding to the hierarchy of the user ID is read from the document storage unit 12, and the electronic document of the read document file is output to the user (step C'9), End the process.

<How to create a hierarchy / user ID correspondence table>
The method for creating the hierarchy / user ID correspondence table is created in the same manner as in the first embodiment shown in FIG.

<How to create a document correspondence hierarchy table>
The document correspondence hierarchy table is created in the same manner as in the first embodiment shown in FIGS. The document correspondence hierarchy table is created by the document division information creation unit 18.

<Setting method of split file>
Next, a method for setting a divided file will be described with reference to FIGS. FIG. 16 is a flowchart for explaining a method for setting a divided file, and FIG. 17 is an explanatory schematic diagram thereof.

  First, the document division information creating unit 18 determines whether or not to perform document division (step E1). The document division information creating unit 18 starts the document division starting character position M ′ (where 1 ≦ M ′ ≦ M) and the hierarchy N ′ specified for the starting character position M ′ (where 1 ≦ N ′ ≦ N). Are input from the input unit 13, it is determined that the document is to be divided (step E1 / Yes), and the start character position M ′ and the hierarchy N ′ are set in the document correspondence hierarchy table (step E2, E3) In this case, the document division information creation unit 18 saves the document division information in a table in which the division order, the division file name, and the hierarchy N ′ are associated with each other and stored in the document division information storage unit 19. (Step E4) Further, the document division information creation unit 18 cuts out the electronic document up to the start character position M ′, and associates the layer N ′ with the division file name and stores it in the document storage unit 12 (Step E5). .

  The document division information creating unit 18 performs the above-described series of processing of Steps E1 to E5 until there is no part where document division is performed. When it is determined that the document division is finished (Step E6 / Yes), the processing is finished.

  Next, the document output unit 17 sets 1 (lowest hierarchy) in the register R1 (step C5), and determines whether or not a user ID is registered in the hierarchy set in the register R1 (step C6). If the user ID is not registered in the hierarchy set in the register R1 (step C6 / No), the document output unit 17 adds one hierarchy set in the register R1 (R1 = R1 + 1) (step C7 ). Then, it is determined whether or not the hierarchy set in the register R1 is greater than N (the highest hierarchy) (step C8). If the hierarchy set in the register R1 is greater than N (the highest hierarchy) (step C8 / Yes), it is determined that the user ID input from the user terminal device 2 is not registered in the hierarchy / user ID correspondence table storage unit 14 (no user ID), and the process ends.

  In addition, when the user ID is registered in the hierarchy set in the register R1 (Step C6 / Yes), the document output unit 17 determines that the user ID input from the user terminal device 2 is the hierarchy / user. It is determined that it is registered in the ID correspondence table storage unit 14, and based on the document name input from the user terminal device 2, the document division information corresponding to the document name is read from the document division information storage unit 19 (step C '9). Next, based on the document division information read from the document division information storage unit 19 and the hierarchy that can be used by the user, the document output unit 17 converts the divided file of the hierarchy that can be viewed by the user into the document storage unit. Read from 12 (step C'10). In this case, the document output unit 17 reads the division file from the document storage unit 12 in the division order included in the document division information. Next, the document output unit 17 outputs the composite document obtained by combining the divided files read from the document storage unit 12 to the user terminal device 2 (Step C′11), and ends the process.

  For example, it is assumed that the document name input from the user terminal device 2 is the document “Hiragana” shown in FIG. 19A, and the user ID is ID A003 shown in FIG. In this case, the document output unit 17 determines that ID A003 is registered in the hierarchy; 2 as shown in FIG. Then, the document output unit 17 reads out the document division information shown in FIG. 19C corresponding to the document “Hiragana” from the document division information storage unit 19. Then, the document output unit 17 includes the document division information shown in FIG. 19C read from the document division information storage unit 19, the hierarchy shown in FIG. 19B that can be used by the user; Based on the divided files for each access right (hierarchy) shown in FIG. 19 (d) stored in FIG. 12, the divided files in the hierarchy that can be browsed by the user are read from the document storage unit 12 shown in FIG. 19 (d). read out. Then, the document output unit 17 outputs a composite document obtained by combining the divided files shown in FIG. 19E read from the document storage 12 to the user terminal device 2.
