Embodiment 1 FIG.
FIG. 1 is an explanatory diagram illustrating a schematic configuration of a document management system according to the present embodiment. This document management system is a system that later collects documents distributed to a plurality of users in a meeting, a questionnaire, etc., and manages each document collected from each user in association with the user and the original document.

  Therefore, a meeting organizer or the like creates document data using a terminal such as a personal computer, and prepares a distribution to each user by printing out the document data. A document ID that is an identifier is assigned to the document data that is the source of the distribution. In this embodiment, when creating a distribution to each user, the assigned document ID is embedded in the document data itself, and the document ID is recorded in the distribution. In the example shown in FIG. 1, “DOC001” is assigned as the document ID to the document data that is the creation source of the distribution, and each distribution to “Mr. A”, “Mr. B”,. Shows a state where the document ID “DOC001” is recorded.

  It is assumed that the annotations written by each user are included in the distributed material after the conference. In this system, these distributions are read by a scanner device or the like, and the obtained read data is stored in association with the original document data and each user. Therefore, when reading the distribution, a user ID for identifying each user and a read data ID for identifying read data are assigned, and the document ID, user ID, and read data are stored in association with each other. The example illustrated in FIG. 1 illustrates a state in which a user ID “USR001” and a read data ID “SCN001” are assigned to the distribution of “Mr. A”.

  These three relationships are registered in a database prepared in a document server 200 (see FIG. 3) described later. FIG. 2 is an explanatory diagram for explaining the configuration of a database prepared in the document server 200. In the present embodiment, a document management database 205c (hereinafter referred to as document management DB 205c) that associates original document data with read data obtained by reading a document collected from each user, and a read data management database 205d that associates read data with each user. Document management is performed using (hereinafter, read data management DB 205d).

  Therefore, when the relationship shown in FIG. 1 is registered in each database, in the document management DB 205c, between the document ID “DOC001” and the read data IDs “SCN001”, “SCN002”,..., “SCNXXX” of each read data In the read data management DB, between the read data IDs “SCN001”, “SCN002”,..., “SCNXXX” and the user IDs “USR001”, “USR002”,. Is associated.

  FIG. 3 is a block diagram showing the overall configuration of the document management system according to the present embodiment. The document management system includes an administrator terminal 100 used by an administrator who performs registration work, a document server 200 that performs document management, a digital multifunction peripheral 300 that performs print output, and a user terminal 400 that is used by a user. The devices are connected via a communication network N.

  The administrator terminal 100 is a personal computer, for example. The administrator terminal 100 includes a control unit 101 that controls the entire apparatus, an operation unit 103 that receives operations of the administrator, a display unit 104 that displays information to be notified to the administrator, and communication for connection to the communication network N.

Next, each database provided in the document server 200 will be described.
FIG. 4 is a conceptual diagram showing the configuration of the document management DB 205c. In the document management DB 205c, a document ID, a document data storage destination, a read data ID, a privileged password, and a contact address are registered in association with each other. The document ID is an identifier assigned to the document data that is a creation source of the delivery to the user, and is issued by the document server 200 when the document data is fetched. The document data storage destination is information indicating the storage destination of the captured document data. That is, the storage position in the document data storage area 205a prepared in the storage unit 205 of the document server 200 is shown. The read data ID is an identifier given to the read data of the document distributed to each user, and is issued by the document data 200 when the read data is taken. Here, one document data ID is registered in association with one or a plurality of read data IDs.

  The privileged password is a password for authenticating a privileged user (for example, an administrator of the document server 200) who can view all read data associated with each document data. The contact address is a notification address used when notifying the user that registration of the read data is completed. An e-mail address can be used as the contact address.

  FIG. 5 is a conceptual diagram showing the configuration of the read data management DB 205d. In the read data management DB 205d, a read data ID, a read data storage destination, and a user ID are registered in association with each other. As described above, the read data ID is an identifier given to the read data of the document distributed to each user. The read data storage destination is information indicating the storage destination of the read data that has been taken in. That is, the storage position in the read data storage area 205b prepared in the storage unit 205 of the document server 200 is shown. The user ID is an identifier for identifying each user, and is assigned in advance to each user who uses this system. Here, one read data is registered in association with one user ID, and by referring to the user ID, it is possible to determine which user the read data is. .

  In the present embodiment, the two databases 205c and 205d are used to associate the document data, the read data, and the user. However, the database structure is not limited to these, and one database is used. It is also possible to prescribe the relationship between the three parties.

  FIG. 6 is a conceptual diagram showing the configuration of the user management DB 205e. In the user management DB 205e, a user ID, a user name, and a password are registered in association with each other. The user ID is an identifier for identifying each user as described above. The user name is the name of the user. The password is a password for authenticating a user who can view the read data associated with the user ID.

The operation of the document management system according to this embodiment will be described below.
FIG. 7 is a flowchart for explaining the procedure of processing executed when registering document data. This registration work is performed by an administrator using the administrator terminal 100. First, the administrator terminal 100 accepts designation of document data to be registered through the operation unit 103 (step S10). Further, the administrator terminal 100 receives the privileged password registered in association with the designated document data, one or a plurality of user IDs, and a contact address through the operation unit 103 (steps S11 to S13). Then, the document data specified in step S10 and the input data received in steps S11 to S13 are transmitted to the document server 200 through the communication unit 105 (step S14).

  When the document server 200 receives document data and input data transmitted from the administrator terminal 100 (step S15), the document server 200 issues a document ID assigned to the document data (step S16). The document ID to be assigned is generated by the control unit 201 according to a predetermined rule. After issuing the document ID, the document server 200 embeds the document ID in the document data (step S17). Here, embedding a document ID means adding a document ID, which is character data, to document data. In the present embodiment, the document ID based on the character data is embedded, but a form such as a two-dimensional barcode that can be easily recognized by a computer may be embedded.

  Next, printing is performed for the number of user IDs based on the document data in which the document ID is embedded (step S18). Specifically, a print job is generated based on the document data in which the document ID is embedded, and the generated print job is transmitted to the digital multifunction peripheral 300 to perform print output. At this time, setting the number of copies to the number of user IDs saves the administrator from having to specify the number of copies to be output.

  Next, document data and input data are registered (step S19). Specifically, the issued document ID is registered in the document management DB 205c, and the received document data is stored in an appropriate storage location in the document data storage area 205a. Then, the storage location information, privileged password, and contact address are associated with the document ID and registered in the document management DB 205c. After the registration is completed, the document server 200 transmits a registration completion notification to the administrator terminal 100 (step S20).

  When the administrator terminal 100 receives the registration completion notification transmitted from the document server 200 (step S21), the administrator terminal 100 notifies the administrator that registration has been completed (step S22), and ends the processing according to this flowchart.

  Next, a procedure for registering read data obtained by reading a distribution (original) distributed to each user will be described. FIG. 8 is a flowchart for explaining the procedure of processing executed when registering read data. This registration work is performed by each user using the digital multifunction peripheral 300. First, the digital multifunction peripheral 300 receives a user ID and a user password through the operation unit 303 (steps S30 and S31).

  Next, the digital multi-function peripheral 300 reads the original (step S32), and transmits the obtained read data and the input data received in steps S30 and S31 to the document server 200 (step S33).

  When the document server 200 receives the read data and the input data (step S34), the document server 200 extracts the document ID from the read data (step S35). Since the distributed material distributed to each user is a manuscript with a document ID added, when extracting the document ID from the read data of the manuscript, the document ID can be extracted by using an existing character recognition technology. it can. When a two-dimensional barcode or the like is added as the document ID, the document ID is extracted by using an existing pattern recognition technique.

  Next, the document server 200 issues a read data ID assigned to the received read data (step S36). The read data ID to be allocated is generated by the control unit 201 according to a predetermined rule. Next, the read data is registered based on the extracted document ID and the issued read data ID (step S37). Specifically, the document management DB 205c is searched using the extracted document ID as a search key, and the read data ID issued in association with the searched document ID is registered.

  Next, the control unit 201 of the document server 200 checks the user ID and password by referring to the user management DB 205e (step S38), and determines whether authentication is possible (step S39). When the authentication cannot be performed (S39: NO), the control unit 201 performs error processing (step S40). Specifically, a process for deleting the contents registered in step S37 is performed.

  When it is determined that the user has been authenticated (S39: YES), the read data management DB 205d is updated (step S41). Specifically, the issued read data ID is registered in the read data management DB 205d, and the received read data is stored in an appropriate storage location in the read data storage area 205b. Then, the storage location information and the user ID are associated with the registered read data ID and registered in the read data management DB 205d. After the registration is completed, the document server 200 transmits a registration completion notification to the digital multi-function peripheral 300 (step S42).

  When the digital multifunction peripheral 300 receives the registration completion notification transmitted from the document server 200 (step S43), the digital multifunction peripheral 300 notifies the user that the registration is completed (step S44), and ends the processing according to this flowchart.

  Next, a procedure when each user reads the read data and document data registered in the document server 200 will be described. FIG. 9 is a flowchart for explaining the procedure of processing executed when reading the read data and document data. This reading operation is performed by each user using the user terminal 400. First, the user terminal 400 receives a document ID, a user ID, and a user password through the operation unit 403 (steps S50 to S52). Then, the received input data is transmitted to the document server 200 (step S53).

  When the document server 200 receives the input data transmitted from the user terminal 400 (step S54), the document server 200 searches the document management DB 205c using the document ID included in the received input data as a search key, and associates it with the document ID. The read data ID is acquired (step S55). Then, the control unit 201 of the document server 200 searches the corresponding user ID by referring to the reading data management DB 205d using the reading data ID as a search key (step S56).

  As a result of searching the read data management DB 205d, the control unit 201 determines whether there is a matching user ID (step S57). When it is determined that there is no matching user ID (S57: NO), the control unit 201 performs error processing (step S58). Specifically, a process for transmitting a message indicating that there is no matching user ID to the user terminal 400 is performed.

  If it is determined that there is a matching user ID (S57: YES), information on the storage location of the read data is acquired from the read data management DB 205d, and the read data of the user stored in the read data storage area 205b is read. (Step S59). Further, information on the storage location of the document data associated with the read data ID acquired in step S55 is acquired from the document management DB 205c, and the document data stored in the document data storage area 205a is read (step S60). . Then, the read reading data and document data are transmitted to the user terminal 400 (step S61).

  When the user terminal 400 receives the read data and document data transmitted from the document server 200 (step S62), the process according to this flowchart is terminated. The user can browse, edit, and print by operating the operation unit 403 of the user terminal 400 and opening the read data and document data from an appropriate application program. At this time, user authentication may be further performed at the user terminal 400, and browsing, editing, and printing may be performed only when authentication is performed. Further, the control unit 401 of the user terminal 400 may automatically display the read data and document data on the display unit 404 when the read data and document data are received in step S62.

  In the flowchart shown in FIG. 9, the user terminal 400 accepts the user ID and the user password, but the privileged password may be accepted. In this case, the user terminal 400 transmits the document ID and the privilege password to the document server 200. The document server 200 that has received the document ID and the privileged password acquires all the associated read data IDs from the document management DB 205c, reads all the read data from the read data storage area 205b, and sends it to the user terminal 400 together with the document data. Send. Further, when a privileged password is accepted, it is not always necessary to read out all read data associated with the document ID, and only arbitrary read data selected by a privileged password user (such as an administrator) is read out. It is good.

  In this embodiment, the document data and the read data are managed based on the document ID assigned to the document data. However, it is possible to associate the two without assigning the document ID. For example, when registering the read data in association with the document data, a print image of the already registered document data is created and a difference from the read data is calculated. Then, it can be determined that the data with the smallest calculated difference is the document data of the original creation source, and the read data can be registered in association with the document data.

Embodiment 2. FIG.
In the first embodiment, only the document ID is embedded in the document data. However, the user ID of each user may be embedded.

  FIG. 10 is a flowchart for explaining the procedure of processing executed when registering document data. This registration work is performed by an administrator using the administrator terminal 100. First, the administrator terminal 100 accepts designation of document data to be registered through the operation unit 103 (step S70). Further, the administrator terminal 100 receives a privileged password, one or more user IDs, and a contact address registered in association with the designated document data through the operation unit 103 (steps S71 to S73). Then, the document data specified in step S70 and the input data received in steps S71 to S73 are transmitted to the document server 200 through the communication unit 105 (step S74).

  When the document server 200 receives the document data and input data transmitted from the administrator terminal 100 (step S75), the document server 200 issues a document ID to be assigned to the document data (step S76). The document ID to be assigned is generated by the control unit 201 according to a predetermined rule. After issuing the document ID, the document server 200 embeds the document ID in the document data (step S77). Here, embedding a document ID means adding a document ID, which is character data, to document data. Further, a configuration using a two-dimensional code or the like may be used.

  Next, document data and input data are registered (step S78). Specifically, the issued document ID is registered in the document management DB 205c, and the received document data is stored in an appropriate storage location in the document data storage area 205a. Then, the storage location information, privileged password, and contact address are associated with the document ID and registered in the document management DB 205c.

  Next, a print image of the document is generated based on the received document data (step S79), and a user ID is embedded in the generated print image (step S80). Here, the embedding of the user ID means that the user ID is combined with the print image, and the image processing unit 204 performs the combining process. Then, a print job is generated based on the print image in which the user ID is embedded, and printing is performed by transmitting the generated print job to the digital multi-function peripheral 300 (step S81).

  Next, the control unit 201 determines whether or not the processing for all users having the received user ID has been completed (step S82), and when determining that the processing has not been completed (S82: NO), the control unit 201 The process returns to step S79. When it is determined that the processing for all users has been completed (S82: YES), a registration completion notification is transmitted to the administrator terminal 100 (step S83).

  When the administrator terminal 100 receives the registration completion notification transmitted from the document server 200 (step S84), the administrator terminal 100 notifies the administrator that the registration is completed (step S85), and ends the processing according to this flowchart.

  As described above, in this embodiment, each user's ID is embedded in the document to be distributed to each user, so that it is not necessary for each user to input the user ID and password when registering the read data. For example, an administrator can perform registration work in a lump.

Embodiment 3 FIG.
In the first and second embodiments, the read data read by the digital multi-function peripheral 300 is registered in association with the document data. However, the original distributed to each user, the original read by the digital multi-function peripheral 300, and The difference is only the presence or absence of annotations written by the user, so it is not always necessary to store the entire read data, and the extracted data that extracts only the annotation part is stored in each user and the original document data. It is good also as a structure linked and memorize | stored.

  FIG. 11 is an explanatory diagram illustrating a schematic configuration of the document management system according to the present embodiment. In this embodiment, when creating a distribution for each user, the document ID assigned to the document data is embedded in the document data, and the document ID is recorded in the distribution. In the example shown in FIG. 11, “DOC001” is assigned as the document ID to the document data that is the creation source of the distribution, and the document ID “DOC001” is assigned to the distribution to “Mr. A”,. Is shown.

  It is assumed that the annotations written by each user are included in the distributed material after the conference. In this system, these distributions are read by a scanner device or the like, and an annotation portion written by each user is extracted as annotation data from the obtained read data. Then, the annotation ID assigned to the annotation data, the user ID set for each user, and the document ID are registered in the database.

  FIG. 12 is an explanatory diagram for explaining the configuration of a database prepared in the document server 200. In the present embodiment, a document management database 215c (hereinafter referred to as document management DB 215c) that associates original document data with read data obtained by reading a document distributed from each user, and associates annotation data extracted from the read data with each user. Document management is performed using the annotation data management database 215d (hereinafter, the annotation data management DB 215d).

  FIG. 13 is a conceptual diagram showing the configuration of the document management DB 215c. In the document management DB 215c, a document ID, a document data storage destination, an annotation data ID, a privileged password, and a contact address are registered in association with each other. The document ID is an identifier assigned to the document data that is a creation source of a delivery to the user, and is issued by the document server 200 when taking in the document data. The document data storage destination is information indicating the storage destination of the captured document data. That is, the storage position in the document data storage area 205a prepared in the storage unit 205 of the document server 200 is shown. The annotation data ID is an identifier given to the annotation data extracted from the read data, and is issued by the document server 200 when the extraction of the annotation data from the read data is completed. Here, one or more annotation data IDs are associated with one document data ID and registered.

  The privileged password is a password for authenticating a privileged user (for example, an administrator of the document server 200) who can view all annotation data associated with each document data. The contact address is a notification address used when notifying the user that registration of annotation data has been completed. An e-mail address can be used as the contact address.

  FIG. 14 is a conceptual diagram showing the configuration of the annotation data management DB 215d. In the annotation data management DB 215d, the annotation data ID, the annotation data storage destination, and the user ID are registered in association with each other. The annotation data ID is an identifier for identifying the annotation data extracted from the read data as described above. The annotation data storage destination is information indicating the storage location of the extracted annotation data. That is, the storage position in the storage unit 205 is shown. The user ID is an identifier for identifying each user, and is assigned in advance to each user who uses this system. Here, one user ID is associated with one annotation data, and it is configured to be able to determine which user the annotation data is by referring to the user ID.

  The operation of the document management system according to this embodiment will be described below. The document data registration process is exactly the same as that of the first embodiment, and thus the description thereof is omitted.

  FIG. 15 is a flowchart for explaining the procedure of processing executed when registering annotation data. This registration work is performed by each user using the digital multifunction peripheral 300. First, the digital multi-function peripheral 300 receives a user ID and a user password through the operation unit 303 (steps S100 and S101).

  Next, the digital multifunction peripheral 300 reads the original (step S102), and transmits the obtained read data and the input data received in steps S100 and S101 to the document server 200 (step S103).

  When the document server 200 receives the read data and the input data (step S104), the document server 200 extracts the document ID and the annotation data from the read data (step S105). The distributed material distributed to each user is a document with a document ID and an annotation added by each user. Therefore, when the document ID is extracted from the read data of the original, the document ID can be extracted by using an existing character recognition technique. In addition, an annotation added by using an existing handwritten character recognition technique can be extracted as annotation data.

  Next, the document server 200 issues an annotation data ID to be assigned to the extracted annotation data (step S106). The annotation data ID to be assigned is generated by the control unit 201 according to a predetermined rule. Next, annotation data is registered based on the extracted document ID and the issued annotation data ID (step S107). Specifically, the document management DB 215c is searched using the extracted document ID as a search key, and the annotation data ID issued in association with the searched document ID is registered.

  Next, the control unit 201 of the document server 200 checks the user ID and password by referring to the user management DB 205e (step S108), and determines whether authentication is possible (step S109). When the authentication cannot be performed (S109: NO), the control unit 201 performs an error process (step S110). Specifically, a process for deleting the contents registered in step S107 is performed.

  If it is determined that the user has been authenticated (S109: YES), the annotation data management DB 215d is updated (step S111). Specifically, the issued annotation data ID is registered in the annotation data management DB 215d, and the extracted annotation data is stored in an appropriate storage location. Then, the storage location information and the user ID are associated with the registered annotation data ID and registered in the annotation data management DB 215d. After the registration is completed, the document server 200 transmits a registration completion notification to the digital multi-function peripheral 300 (step S112).

  When the digital multifunction peripheral 300 receives the registration completion notification transmitted from the document server 200 (step S113), the digital multifunction peripheral 300 notifies the user that the registration is completed (step S114), and ends the processing according to this flowchart.

  FIG. 16 is a flowchart for explaining the procedure of processing executed when reading annotation data and document data. This reading operation is performed by each user using the user terminal 400. First, the user terminal 400 receives a document ID, a user ID, and a user password through the operation unit 403 (steps S120 to S122). Then, the received input data is transmitted to the document server 200 (step S123).

  When the document server 200 receives input data transmitted from the user terminal 400 (step S124), the document server 200 searches the document management DB 215c using the document ID included in the received input data as a search key, and associates it with the document ID. Annotated annotation data ID is acquired (step S125). Then, the control unit 201 of the document server 200 searches the corresponding user ID by referring to the annotation data management DB 215d using the annotation data ID as a search key (step S126).

  As a result of searching the annotation data management DB 215d, the control unit 201 determines whether there is a matching user ID (step S127). If it is determined that there is no matching user ID (S127: NO), the control unit 201 performs error processing (step S128). Specifically, a process for transmitting a message indicating that there is no matching user ID to the user terminal 400 is performed.

  If it is determined that there is a matching user ID (S127: YES), the annotation data storage destination information is acquired from the annotation data management DB 215d, and the user annotation data stored in the storage unit 205 is read (step S120). S129). Further, information on the storage destination of the document data associated with the annotation data ID acquired in step S125 is acquired from the document management DB 215c, and the document data stored in the document data storage area 205a is read (step S130). . Then, the read annotation data and document data are transmitted to the user terminal 400 (step S131).

  When the user terminal 400 receives the annotation data and document data transmitted from the document server 200 (step S132), the process according to this flowchart is terminated. The user can browse, edit, and print by operating the operation unit 403 of the user terminal 400 and opening the annotation data and document data from an appropriate application program. At this time, user authentication may be further performed at the user terminal 400, and browsing, editing, and printing may be performed only when authentication is performed.

  In the present embodiment, the document server 200 transmits the annotation data and the document data to the user terminal 400 that requested it. However, the print image is created from the document data, and the annotation data is added to the created print image. Then, the synthesized image obtained may be transmitted to the user terminal 400 together with the document data.

  In the flowchart shown in FIG. 16, the user terminal 400 accepts the user ID and the user password. However, the privileged password may be accepted. In this case, the user terminal 400 transmits the document ID and the privilege password to the document server 200. The document server 200 that has received the document ID and the privileged password acquires all the associated annotation data IDs from the document management DB 215c, reads all the annotation data, and transmits them to the user terminal 400 together with the document data. Further, when a privileged password is accepted, it is not always necessary to read out all the annotation data associated with the document ID, and only arbitrary annotation data selected by a privileged password user (such as an administrator) is read out. It is good.

  As described above, in the present embodiment, since only the annotation data extracted from the read data is stored in the storage unit 205 of the document server 200, the data amount can be reduced.
