Description

  The present invention relates to a classification management apparatus for classifying and managing various documents and files.

In companies and the like, documents are created every day, and the amount of the documents is enormous. Therefore, there arises a problem of how to classify and manage these documents. In general, the created document is filed according to a certain system. In addition, a database system for registering information such as the title name, storage location, and retention period of a document filed in this way has been developed (see, for example, the following patent document).
JP 2000-335163 A

  Recently, due to legal requirements represented by the Personal Information Protection Law, security has been required more than ever before to store various documents. However, there is a trade-off between the safety of document storage and the convenience of reuse. The more strictly the document is stored, the more difficult it is to browse and take out the document, resulting in a decrease in business efficiency.

  In order to mediate the trade-off between safety and convenience, it is possible to evaluate the confidentiality of each document and to take security measures corresponding to the importance. However, at present, there are no effective tools for evaluating the importance of a document, and humans must actually make a judgment by looking through the contents of the document. Then, since the place which depends on an individual's knowledge and experience becomes large, judgment criteria will vary and there is a possibility that the evaluation of importance may not be unified in the whole organization. Of course, as the amount of documents to be stored increases, it goes without saying that a great deal of effort is required only by evaluating the importance.

  The present invention has been made in view of the above, and provides a tool that can easily evaluate the confidentiality of a document, and thus favorably supports classification management according to the importance.

  In order to solve the above-described problem, as shown in FIG. 1, a management object such as a document or a file containing documents is classified and managed in a plurality of security classifications. A reference table storage unit 101 that stores a reference table that is a set of records in which category information indicating security categories set correspondingly is described, and a title name assigned to the management object are acquired, and the title name A keyword selection unit 102 that selects keywords included in the reference table from the keywords registered in the reference table, and category information corresponding to the keywords selected by the keyword selection unit 102 is extracted from the reference table, A classification management device 1 is provided that includes a determination result output unit 103 that outputs a security classification to be given to a target management object. It was.

  Here, the “file” is a general term for a document that is bound using a filing tool (ring binder, pipe file, etc.) or a document that contains a document (box file, etc.). “Title name” refers to a title name, a file name, etc., and is usually written on a document or entered on a label attached to a file. “Acquisition” refers to a process of reading from a predetermined storage device or medium, accepting manual input by a user, or receiving via a telecommunication line, and “output” refers to a predetermined storage device or medium. This is the process of writing to the screen, displaying it on the screen of a display, printing, or transmitting via a telecommunication line. The “table” may be a data file in a required format.

  The classification management apparatus 1 according to the present invention has a function of assigning a security classification indicating the confidentiality level based on the title name of a document or file to be stored. Thereby, it is possible to eliminate the complexity of actually judging the importance by looking through the contents of the document, and it is possible to favorably support the classification management and the enforcement of security measures according to the importance.

  In the case where a plurality of keywords are selected by the keyword selection unit 102 or a keyword cannot be selected, and the security classification to be given to the target managed object cannot be uniquely specified, the determination result output unit 103 It is desirable to output notification information for notifying the user of the fact. This is because the evaluation of the importance of such a document or file should be left to human judgment.

  Alternatively, when a plurality of keywords are selected by the keyword selection unit 102, and the security classification to be given to the target managed object cannot be uniquely specified, the determination result output unit 103 has a plurality of keywords corresponding to each keyword. Of the category information, information indicating the category with the highest rank from the viewpoint of security may be output.

  In the record of the reference table stored in the reference table storage unit 101, accompanying information related to storage of the management object including the keyword in the title name is described together with the classification information, and the determination result output unit 103 selects the keyword selection If the incidental information corresponding to the keyword selected by the unit 102 is also extracted from the reference table and output as information relating to storage of the target management object, it becomes more useful for document or file classification management. “Accompanying information” refers to, for example, information indicating ancillary items required for storage of the subject management object (storage period, range allowed for disclosure, history management necessity, copying availability, management location specification, etc. Etc.), filing classifications other than security classifications (stratification such as major classification, middle classification, and minor classification), information indicating the type of filing tool being used, and the like.

  The keyword selection unit 102 and the determination result output unit 103 sequentially acquire the title names of a plurality of managed items, sequentially select the keywords included in each title name, and sequentially classify information corresponding to each keyword. If it is extracted and the classification information related to each of the plurality of managed items is output at once, the determination results for the plurality of managed items can be obtained at a time.

  When configuring the classification management apparatus 1, the computer obtains at least the title name given to the managed item, and selects the keyword included in the title name from the keywords registered in the reference table. A program that functions as the keyword selection unit 102 and the determination result output unit 103 that extracts the category information corresponding to the keyword selected by the keyword selection unit 102 from the reference table and outputs it as the security category to be given to the target management object. It is conceivable to produce it. The program may be a single application program, or may be a script or a macro program (particularly, a macro program that uses the functions of known spreadsheet software or database software) that cooperates with other programs. .

  According to the present invention, the confidentiality level of a document can be easily evaluated, and classification management according to the importance level can be suitably supported.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The classification management apparatus 1 of the present embodiment is mainly a computer that can be directly operated and used by a user. The computer is typically a general-purpose personal computer or workstation, but may be a PDA (Personal Digital Assistant), a mobile phone terminal, or the like.

  For example, as shown in FIG. 2, the computer includes hardware resources such as a processor 1a, a main memory 1b, an auxiliary storage device 1c, a display control device 1d, a display 1e, an operation input device 1f, and a communication interface 1g. Are controlled by a controller (that is, a system controller or an I / O controller) 1h to perform a cooperative operation. The auxiliary storage device 1c is a hard disk drive, a flash memory, an optical disk drive, or the like. The display control device 1d temporarily stores video chips (graphics chips), image data, and the like that generate image data to be displayed based on the drawing instruction received from the processor 1a and send the image data to the display 1e. The video memory etc. The operation input device 1f is a pointing device such as a push button, a keyboard, a mouse, a track pad, or a touch panel that can be operated with fingers. The communication interface 1g is a device for performing information communication via an electric communication line, and is typified by a NIC (Network Interface Card) or a wireless LAN transceiver, but besides these, a USB (Universal Serial Bus), IEEE1394, or the like is used. An interface can also be adopted.

  Normally, a program to be executed by the processor 1a is stored in the auxiliary storage device 1c. When the program is executed, the program is read from the auxiliary storage device 1c into the main memory 1b and decoded by the processor 1a. In this embodiment, a known OS (Operating System) program and various device driver programs attached thereto are installed in advance to mediate use of hardware resources by other programs. In addition, a program necessary for configuring the transaction support apparatus 1 according to the present invention is installed. Then, according to the program, the hardware resources are operated, and functions as the reference table storage unit 101, the management table storage unit 104, the operation input reception unit 105, the keyword selection unit 102, and the determination result output unit 103 shown in FIG. It has become something that demonstrates.

  The function of each part will be described. The reference table storage unit 101 stores a reference table using a required storage area of the main memory 1b or the auxiliary storage device 1c. As shown in FIG. 4, the reference table is a set of records in which keywords and category information indicating security categories set corresponding to the keywords are described. In FIG. 4, each horizontal row is one record related to one keyword. For example, the security classification “V” is set for the keyword “contract”. This means that the security classification “V” should be given to the management item including the keyword “contract” in the title name.

  In the illustrated example, four levels of security classifications “V”, “P”, “C”, and “R” are provided. “V” indicates Vital documents, the document itself is important, legally required to be preserved, and the originality is questioned, or the document has a great influence on the business continuity and business activity continuity. “P” indicates that the management is obliged by Private documents, the enforcement of the Personal Information Protection Law, and the like. “C” indicates Confidential documents, the document itself is important, the recorded content is important, and the information should not be altered, destroyed or leaked. “R” indicates Reference documents, published documents referred to in performing business, distributed publications, and the like. In other words, the confidentiality of management items and the severity or priority of security measures required for storage are divided into a plurality of stages in the order of V, P, C, and R from the top. In other words, it is also a stage of ease of browsing use required for business efficiency. The types of contracts must be kept strictly, but they are not taken out every day or are not shown to many people. Product sales catalogs and the like are public information, and if they cannot be taken out immediately as needed, they may lose opportunities.

  In addition, in the record for each keyword, accompanying information corresponding to the keyword is described. In FIG. 4, the attributes other than the keyword and the security classification are all incidental information, and it is possible to register major classification, middle classification, retention period, disclosure range, necessity of history management, copying availability, management location, and the like. For example, a management item that includes the keyword “score” in the title name belongs to the filing category of “category” as the major category “sales” and “sales activity” as the middle category. Management “○”, copy impossible “○”, and management location “Section Manager”.

  The reference table shown in FIG. 4 is merely an example. The attribute values of keywords, category information, and accompanying information can be appropriately changed. These depend on the customs and culture of each company and organization. In addition, although there are spare attributes in the reference table, the user can register arbitrary data here as necessary. Spare attributes can also be part of the accompanying information.

  The management table storage unit 104 stores a management table using a required storage area of the main memory 1b or the auxiliary storage device 1c. As shown in FIG. 5, the management table describes the title name given to the management object to be stored, the classification information indicating the security classification to be given to the management object, and the accompanying information regarding the storage of the management object Is a set of records to be processed. In FIG. 5, each horizontal row is one record related to one managed item. In principle, the title name, location, and creation year of each managed item are input by a user who wants to classify and manage the managed item. On the other hand, attributes other than the title name, location, and creation year are empty, but the attribute values are written by the determination result output unit 103. Further, the management table includes the number of hits and the attribute of the hit keyword. As will be described later, the number of hits and the hit keyword play a role as notification information.

The operation input receiving unit 105 receives a user operation input via the operation input device 1f. Enumerating opportunities to accept operation inputs
A command for accepting manual entry (ie, addition, modification or deletion) of keywords, classification information, and accompanying information in the reference table, or reading from another data file (stored in the auxiliary storage device 1c in advance) Acceptance of manual entry of title name in management table, or instruction to read from other data file. Security classification of instruction / management thing to determine security classification of management object whose title name is registered in management table For example, an instruction to output the statistical information of the determination result, an instruction to output the determination result of the security classification of the managed object as a data file, and the like.

  The keyword selection unit 102 refers to the management table and acquires a title name registered in the management table. Then, for each acquired title name, the keyword included in the title name is searched and selected from the keywords registered in the reference table.

  The determination result output unit 103 extracts category information corresponding to the keyword selected by the keyword selection unit 102 from the reference table, and outputs it as a security category to be given to the target managed item. In addition, incidental information associated with the same keyword is also extracted from the reference table and output as information related to storage of the target managed item. In addition, for a certain title name, when the keyword selection unit 102 has selected a plurality of keywords or has not been able to select keywords, the security classification to be given to the target management object cannot be uniquely specified. Is notified to the user.

  There are various ways of outputting the category information and the accompanying information. In this embodiment, the category information and the accompanying information extracted from the reference table, the number of hits as notification information, and the hit keyword are the targets in the management table. Are written in the record related to the managed item and displayed on the screen of the display 1e. Also, if necessary, it is printed, stored as a separate data file in a required storage area of the auxiliary storage device 1c, or directed to another computer (not shown) connected via an electric communication line. You can also send it.

  Hereinafter, a procedure of processing executed by the computer according to the program will be described. The program started on the computer displays windows as illustrated in FIGS. 6, 7, and 9 on the display 1e. 6 is a screen that displays the contents of the reference table stored in the reference table storage unit 101, and FIG. 7 or FIG. 9 is a screen that displays the contents of the management table stored in the management table storage unit 104. It is. When the user wants to display the reference table, the user uses the operation input device 1f and clicks the tab “VPCR reference table (A table)” T1 displayed on the screen. The computer that has received this operation displays the reference table display screen shown in FIG. 6 on the display 1e according to the program. On the other hand, when the user wants to display the management table, the user clicks the tab “check screen (table B)” T2 displayed on the screen using the operation input device 1f. The computer that has received this operation displays the management table display screen shown in FIG. 7 or 9 on the display 1e according to the program.

  In order to execute the security classification determination process to be given to each managed item, it is necessary to register the title name of the target managed item in the management table. In that case, the user designates a column (so-called cell, text box, etc.) for inputting a title name on the management table display screen shown in FIG. 7 using the operation input device 1f, and sets an attribute value in the designated column. Enter manually. The computer that has received these operations adds a new title name to the management table in accordance with the operation input, or modifies or deletes the title name already described in the management table according to the operation input.

  If a data file in which the title name of the managed object is described in advance in a required data format, for example, the CSV (Comma Separated Values) format, is created, the title name information is imported into the management table from there (or ). In this case, the user uses the operation input device 1f and clicks a “data fetch” button T3 on the management table display screen shown in FIG. The computer that has received this operation displays a dialog (not shown) for selecting the corresponding data file on the display 1e according to the program. Thereafter, the user selects the corresponding data file from the file group displayed in the list in the dialog. As a result, the computer obtains path information for identifying the selected data file, reads the data file, and writes the title name in the management table.

  Prior to the process of determining the security classification of the managed object, the registration contents of the reference table can be adjusted. In that case, the user uses the operation input device 1f to specify a field for inputting a keyword, classification information, or incidental information on the reference table display screen shown in FIG. 6, and manually inputs an attribute value in the specified field. To do. The computer that has received these operations adds a new keyword or the like to the reference table according to the operation input according to the program, or modifies or deletes the keyword or the like already described in the reference table.

  Similarly to the management table, information can be imported into a reference table from a data file in which keywords, classification information corresponding thereto, and accompanying information are described according to a required data format.

  Accordingly, when the execution of the security classification determination process of the managed object is started, the user clicks the “VPCR determination” button T4 on the management table display screen shown in FIG. 7 using the operation input device 1f. The computer that has received this operation executes the processing procedure shown in the flowchart of FIG. 8 according to the program.

  First, one of the title names registered in the management table is read (step S1). Subsequently, the keywords registered in the reference table are sequentially read (step S2), and the keywords are compared with the title name to determine whether the keyword is included in the title name (step S3). If the keyword is included in the title name, the keyword is temporarily stored as a keyword hit for the title name (step S4), and the hit count is increased by 1 for the title name (step S5). The above steps S2 to S5 try for all the keywords registered in the reference table.

  After the comparison with all the keywords is completed (step S6), the division information and the accompanying information are given to the managed item with the title name. Specifically, the division information and accompanying information described in the hit keyword record are read from the reference table (step S7), and these are written in the title name record in the management table (step S8). However, for the disposal period among the attributes of the management table, it is calculated by referring to the retention period read from the reference table and the creation year of the target management object read from the management table, and written to the management table. And Further, the hit number and the hit keyword are written in the record of the title name in the management table (step S9).

  When the processing of steps S7 to S9 is finished for a certain title name, the process returns to step S1, the next title name is read from the management table, and the same procedure is executed. The process is repeated until the determination process is completed for all title names registered in the management table (step S10).

  FIG. 9 shows an example of a result display when the security classification determination process for managed objects is completed. That is, classification information based on the title name and accompanying information are given to each managed item and reflected on the management table display screen. For example, a managed item with the title “Lease Contract Aka Sasa” is judged as security classification “V” because the title name includes the keyword “Contract”, and is classified into the major category “Sales”. “Sale”, middle class “sales”, preservation period is “7”, disposal period is “2012” (because the creation year is 2004), and the disclosure range is “inside”. The management object with the title “Catalog Delivery List 2003 Aggregation” has the keyword “Catalog Delivery List” in the title name, so it is determined as the security classification “P”, and the major classification “Sales”, the middle classification “Sales promotion”, preservation period is “3”, disposal period is “2007” (because the creation year is 2003), disclosure range is “inside”, and copying is prohibited “○” Yes.

  The number of hits in the management table after the determination processing indicates the number of keywords hit for each title name. In addition, the hit keyword indicates the hit keyword for each title name. If the number of hits is “1” and the number of hit keywords is singular, it can be inferred that the security classification to be given to the managed object is uniquely specified. However, if the number of hits is “2” or more and there are a plurality of hit keywords, it cannot always be said that the security classification to be given to the target management object is uniquely specified. For example, a managed item with the title name “product catalog invoice” includes the keywords “product catalog” and “invoice” in the title name. In the reference table shown in FIG. 4, the security classification corresponding to “Product Catalog” is defined as “R”, and the security classification corresponding to “Invoice” is defined as “P”. Identifying security categories to be given to objects can cause problems. Therefore, it is desirable for a managed object having a hit count of “2” or more and a plurality of hit keywords to be determined by human beings through actual inspection.

  In addition, as in the above example, in a case where a plurality of types of security classifications are given to one managed item by determination based on the title name, it is conceivable to assign a higher ranking classification from the viewpoint of security. That is, when a plurality of keywords are selected as hit keywords in step S3 and a plurality of types of category information corresponding to each keyword are extracted in step S7, the most of the category information in step S8. A mode in which an item indicating a high-order category is written in the management table as a security category to be assigned to the target management object can be employed. If applied to the above example, the security category “P” having a higher rank than the security category “R” is assigned to the management item with the title “product catalog invoice”.

  Further, if no keyword hits the title name, it is natural that a security classification cannot be assigned to the target management object, and a human must actually make a final decision by looking through. For example, the keyword “brochure” is not registered in the reference table shown in FIG. 4, and therefore, no security classification can be assigned to the management object with the title name “brochure”. As shown in FIG. 9, the classification information and the accompanying information are not output to the record of the managed item in which the keyword does not hit. The number of hits and the hit keyword also remain empty (likely, “0” may be displayed for the number of hits).

  Generally speaking, the number of hits in the management table and the attribute value of the hit keyword can be notification information for notifying the user whether or not it is actually necessary to look through the target management item and determine the security classification. This is because the number of hits does not become “1” (including empty) or the hit keyword does not become singular (including empty) in the judgment processing result display is given to the managed object. This is because it indicates the fact that the security classification to be uniquely identified could not be specified. However, the mode of the notification information is not limited to this. For example, on the management table display screen, by changing the title name or record display mode (character color, background color, etc.) of the managed item for which the keyword did not hit, the security classification of the managed item can be uniquely identified. It is also conceivable to notify that there was not.

  By the way, in the classification management apparatus 1 of the present embodiment, it is possible to output statistical information on the determination result of the security classification to be given to the managed object. When outputting statistical information, the user uses the operation input device 1f and clicks the “Create graph” button T5 on the management table display screen shown in FIG. The computer that has received this operation counts the category information assigned to each management item registered in the management table for each category of “V”, “P”, “C”, and “R” according to the program. A statistical table and a graph as illustrated in FIG. 10 are drawn and displayed on the display 1e or printed. The statistical information can be used, for example, in a company or organization to estimate the space, furniture, security system, and the like necessary for storing the accumulated management items.

  Furthermore, it is possible to externally output a data file of the determination result of the security classification to be assigned to the managed object. When it is desired to externally output the data file of the determination result, the user clicks the “data copy” button T6 on the management table display screen shown in FIG. 9 using the operation input device 1f. The computer that has received this operation stores, in accordance with the program, all or part of the title name, classification information, accompanying information, etc. described in the management table in the auxiliary storage device 1c as a data file in accordance with a required data format. Or transmitted to another computer connected via a telecommunication line. For example, the data file can be read and used by known file management software, label printing software, or the like. When it is read and used by label printing software, etc., the label printing mode (font, character size, character color, etc.) according to the classification information and / or accompanying information given to the target management object It is also possible to make the types of label mounts different.

  According to the present embodiment, a document and a management object such as a file collecting documents are classified and managed in a plurality of security classifications, and a keyword and a security classification set corresponding to the keyword The reference table storage unit 101 that stores a reference table that is a set of records in which the classification information indicating is acquired, and the title name given to the management object are acquired, and the keyword included in the title name is The keyword selection unit 102 selected from each keyword registered in the reference table, and the classification information corresponding to the keyword selected by the keyword selection unit 102 is extracted from the reference table, and the security to be given to the target management object Since the classification management apparatus 1 including the determination result output unit 103 that outputs the classification is configured, the document or file It can be automatically granted a security classification indicating the importance of its confidential based on title such as Le. Thereby, it is possible to eliminate the complexity of actually judging the importance by looking through the contents of the document, and it is possible to favorably support the classification management and the enforcement of security measures according to the importance.

  In the case where a plurality of keywords are selected by the keyword selection unit 102 or a keyword cannot be selected, and the security classification to be given to the target managed object cannot be uniquely specified, the determination result output unit 103 Since the notification information for notifying the user of the fact is output, the reliability of the determination result is also ensured.

  Alternatively, when a plurality of keywords are selected by the keyword selection unit 102, and the security classification to be given to the target managed object cannot be uniquely specified, the determination result output unit 103 has a plurality of keywords corresponding to each keyword. Of the category information, information indicating the category with the highest rank from the viewpoint of security may be output.

  In the record of the reference table stored in the reference table storage unit 101, accompanying information related to storage of the management object including the keyword in the title name is described together with the classification information, and the determination result output unit 103 selects the keyword selection Since the accompanying information corresponding to the keyword selected by the unit 102 is also extracted from the reference table and output as information related to storage of the target management object, it is further useful for managing the classification of documents or files.

  The keyword selection unit 102 and the determination result output unit 103 sequentially acquire the title names of a plurality of managed items from the management table, sequentially select the keywords included in each title name, and class corresponding to each keyword Since the information is sequentially extracted from the reference table and the classification information related to each of the plurality of managed items is collectively output, the determination result for the plurality of managed items can be obtained at a time.

  The present invention is not limited to the embodiment described in detail above. In particular, the functions of the respective units shown in FIG. 1 or FIG. 3 are not distributed to a plurality of computers connected to each other and integrated to constitute the classification management apparatus 1 according to the present invention.

  In addition, the specific configuration and processing procedure of each part can be variously modified without departing from the spirit of the present invention.
