As a result, when it is determined that the keyword is included in the document data, the document data is not stored in the document management system, but temporarily stored in the document registration system, and the document data is stored in the document management system. The administrator of the document registration system is notified that the information has not been stored in the document registration system.

  When it is determined that the keyword is included in the document data, the document data is stored in the document management system, and the document data including the keyword is stored in the document management system. Notify the registration system administrator.

  Accordingly, it is possible to prevent unconditionally registering document data having confidential information registered as a keyword in the document management system, and an administrator of the document registration system can store the document data including the keyword in the document management system. It is possible to know whether or not the data has been stored, and to take necessary measures, so that the security as the document registration system can be strengthened.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 is a block diagram showing a configuration of a network system including a document registration system according to an embodiment of the present invention.

  In FIG. 1, reference numeral 1 denotes a multi-function machine having functions such as reading (scanning) of a document image, transmission / reception of a facsimile (FAX), printing, and the like, and is obtained by receiving image data obtained by scanning or FAX. The received image data is transmitted to the document registration system 4 via the network 12. Here, such image data is referred to as “document”.

  Reference numeral 2 denotes a document management system composed of a personal computer, which stores and manages documents as an application service provider.

  Reference numeral 3 denotes a mail server, which is connected to the network 12 in order to realize electronic mail transmission from the document management system 2 to the administrator of the document registration system 4.

  Reference numeral 4 denotes a document registration system composed of a personal computer, which is operated by a document storage application.

  A personal computer constituting the document registration system 4 may realize the functions of the document management system 2. However, in the embodiment shown in FIG. It is assumed that the system 2 is composed of separate personal computers.

  The document registration system 4 includes a CPU 5, ROM 6, RAM 7, HD 8, input device 9, display 10, and I / F 11.

  The CPU 5 performs calculation processing and program execution processing in the document registration system 4.

  The ROM 6 stores basic software for operating the internal device functions of the document registration system 4.

  The RAM 7 temporarily loads the software shown in FIG. 2 from the ROM 6 or the HD 8 so that the CPU 5 can execute it.

  The HD 8 is a large storage capacity hard disk for storing an OS (Operating System), a document storage application, and mail software.

  The input device 9 is an input device such as a keyboard and a pointing device (mouse) for operating a GUI (graphical user interface) of the document registration system 4.

  The display 10 is an image display device for displaying a software screen and an execution state.

  The I / F 11 is a network interface for communicating the document registration system 4 with the multifunction device 1, the document management system 2, the mail server 3, an external communication device, another system, or the Internet via the network 12.

  The network 12 is a local area network (LAN) and can be connected to the Internet.

  FIG. 2 is a diagram showing a configuration of software that operates in the document registration system 4.

  The OS 22 is located in the upper layer of the BIOS (Basic Input / Output System) 21, and the document storage application 23 and the mail software 24 are located in the upper layer of the OS 22.

  The BIOS 21 and the OS 22 perform operation control of each hardware constituting the document registration system 4. Communication on the network 12 is performed using, for example, TCP / IP (Transmission Control Protocol / Internet Protocol), and the OS 22 handles the protocol.

  The document storage application 23 implements functions of communication with the multifunction machine 1, storage of documents in the document management system 2, and mail notification.

  The mail software 24 is software for transmitting information on the success or failure of document storage passed by the mail notification function of the document storage application 23 and warning information in the security mode as electronic mail.

  FIG. 3 is a diagram showing the configuration of the document storage application 23.

  The protocol control unit 31 transmits and receives a document between the multifunction device 1 and the document registration system 4 using a protocol such as FTP (File Transfer Protocol), for example. When a document is transmitted from the multifunction device 1 to the document registration system 4, the protocol control unit 31 notifies the general control unit 33 to that effect, and the general control unit 33 receives the notification. Then, image processing is started, and processing in the document storage unit 32 is started.

  The document storage unit 32 stores the document received by the protocol control unit 31 from the multifunction device 1 in a designated storage location of the document management system 2.

  The overall control unit (server core) 33 manages the delivery of documents from the protocol control unit 31 to the document storage unit 32, and the operation status (successful reception, storage success, error, etc.) of the protocol control unit 31 or the document storage unit 32. Information creation for the mail notification function, information delivery to the mail software 24, mail transmission request, etc. are performed.

  The setting program 35 is a program for setting the operation of the document storage application 23. The setting program 35 sets in advance items necessary for registering a document from the multifunction device 1 to the document management system 2, and when actually sending a document, the document storage application 23 automatically performs registration processing according to the setting contents. Do.

  The setting storage unit 34 is a part for storing the settings created by the setting program 35. When the document is registered, the information stored in the setting storage unit 34 is read from the overall control unit 33, and the processing is executed. Automatic registration in the registration system 4 is possible. In the setting storage unit 34, the setting information may be stored in a general text format, profile, or the like. In addition, the software that displays the file as text is stored in a file format that cannot display the contents. As long as the document storage application 23 can read the setting contents, the form is not limited.

  Next, with reference to FIG. 4, the setting process procedure and setting items by the setting program 35 of the document storage application 23 will be described in detail.

  FIG. 4 is a flowchart showing a procedure of processing performed by the setting program 35 shown in FIG.

  First, in step S101, execution of the setting program 35 of the document storage application 23 is started. The setting program 35 is provided in the form of an executable program so that the user can perform a setting operation separately from the document registration process of the document storage application 23.

  In step S102, a destination name is set. The name of the destination is a registered destination of the document when the document read by the scan / fax function of the multifunction device 1 is registered in the document management system 2. The document management system is displayed on the operation panel of the multifunction device 1. A plurality of cabinet folders included in 2 are displayed. The user selects a desired destination (cabinet folder) from among them. As a result, the document can be registered in the cabinet folder of the selected document management system 2. The cabinet folder is a so-called concept of a document folder arranged in a bookcase, and anyone can browse without limitation.

  In step S103, a communication protocol is selected. In this case, the multifunction device 1 selects a protocol for transmitting an image to the document registration system 4, and a protocol suitable for the multifunction device 1 is selected from several types of protocols.

  In step S104, detailed settings necessary for operating the protocol selected in step S103 are performed. For example, when the protocol is FTP, the user name and password for logging in to the FTP server, and the actual document transmission destination viewed from the multifunction device 1 when the document is sent from the multifunction device 1 to the document registration system 4 Set the FTP folder and so on. In the document registration process, the protocol control unit 31 shown in FIG. 3 reads the document from the FTP server based on the setting contents set in this way, and then proceeds with the process.

  In step S105, image processing is set. In this step, the setting required for the image storage application 23 to perform image processing such as changing the format of the document sent from the multifunction device 1 or converting the format to a document format that can be registered in the document management system 2 is performed. In step S105.

  In step S106, a document storage destination is set. The storage destination is a cabinet folder in the document management system 2, and the document storage unit 32 of the document storage application 23 registers the document in the document management system 2 according to this setting. The destination displayed on the operation panel of the multifunction device 1, the FTP folder in the document registration system 4 where the multifunction device 1 actually transmits the document, and the storage destination set in step S106 are set in cooperation. Thus, the document storage application 23 can automatically register a document from the multifunction device 1 to the document management system 2.

  In step S107, a keyword including a character string and a word related to confidential information is set, and the keyword is stored in association with the cabinet / folder. Multiple keywords can be set. The keyword storage form is conceptually stored in a profile format called a keyword list.

  In step S108, a security mode is set. In the security mode, if the keyword set in step S107 is included in the character information on the document to be registered in the document management system 2, the document registration is not performed, and the management of the document registration system 4 is informed. A security mode 1 for notifying a person by e-mail and a security mode 2 for notifying the administrator of the document registration system 4 by e-mail that a document is registered but a keyword is included in the document. In S <b> 108, the user selects and sets one of the security modes 1, 2, and a normal document registration mode without executing either security mode.

  In step S109, the various settings performed in steps S102 to S108 are saved.

  Next, in step S110, execution of the setting program 35 of the document storage application 23 is once ended.

  Next, in step S111, using the settings saved in step S109, an operation for setting the items to be set in the multifunction device 1, such as the destination and protocol settings, to the multifunction device 1 is started.

  In step S112, an actual setting operation is performed on the multi function device 1. Here, a remote user interface that takes out necessary information in an address book format and provides the multi function device 1 to the network environment using HTTP (Hypertext Transfer Protocol) is used. To register. Since the registration operation and the setting procedure in the multifunction device 1 are already known techniques, detailed description thereof will be omitted.

  Finally, in step S113, the setting operation for the multifunction machine 1 is terminated.

  After the setting to the multifunction device 1 is completed, document transmission from the multifunction device 1 becomes valid. In other words, the end user first selects the document transmission mode using the operation panel provided in the multifunction device 1, and then selects the destination to which the document is to be registered as the destination displayed on the operation panel of the multifunction device 1. Select from the above, set the document to the document table for scanning, select the FAX document stored in the MFP 1 for FAX reception, and finally execute the start button to start the processing of the MFP 1 As a result, document transmission from the multifunction device 1 to the document registration system 4 becomes possible. At this time, if the overall control unit 33, protocol control unit 31, and document storage unit 32 of the document storage application 23 shown in FIG. 3 are activated on the document registration system 4, the document registration system 4 starts from the multifunction device 1. This is an environment in which documents can be automatically stored in the document management system 2.

  FIG. 5 and FIG. 6 are flowcharts showing a series of processing procedures in which the document storage application 23 registers a document in the document management system 2. Here, an e-mail notification function and the like are also shown. FIG. 8 is a diagram conceptually illustrating a document and a processing flow in the entire document registration process in which the document registration system 4 registers the document transmitted from the multifunction device 1 in the document management system 2. The above processing will be described below with reference to the flowcharts of FIGS. 5 and 6 and will be described with reference to FIG. 8 as appropriate.

  Note that the mail server 3, the mail notification function of the document storage application 23 on the document registration system 4, and the mail software 24 shown in FIG. 2 use a general protocol such as SMTP for transmission and POP3 for reception.

  First, in step S201 in FIG. 5, the document storage application 23 is started. This corresponds to activation of the overall control unit 33, the protocol control unit 31, and the document storage unit 32 constituting the document storage application 23 shown in FIG.

  In step S202, the service is started by the FTP server, and the apparatus waits for reception by the FTP server. Here, an example using the FTP protocol is shown, and the document that is controlled by the protocol control unit 31 and transmitted from the MFP 1 (P2 in FIG. 8) is received by the document storage application 23, but the protocol is not FTP. Also good. In this step, the entire process shifts to a state of waiting for reception, and the protocol may be any environment in which both the multifunction device 1 and the protocol control unit 31 of the document storage application 23 can perform data communication.

  In step S203, it is determined whether or not a document has been received. When the protocol control unit 31 receives the document, it notifies the overall control unit 33 to that effect, so the overall control unit 33 makes this determination based on the presence or absence of this notification. If there is no document reception, the process returns to step S202 to continue the document reception waiting state. On the other hand, if a document has been received, the process proceeds to step S204.

  In step S204, it is determined whether the document reception is successful. If the document reception has failed, the process proceeds to step S219 to notify the administrator of the document registration system 4 of the document reception failure by e-mail. If the document reception is successful, the process proceeds to step S205.

  In step S205, image processing is performed on the document transmitted from the multifunction device 1. That is, mainly, the document transmitted from the multifunction device 1 is converted into a document format that can be input by the document management system 2. This is because the document management system 2 does not necessarily support the document format transmitted by the multifunction device 1.

  In step S206, it is determined whether or not a security mode is designated. The security mode is set by a setting process (step S108 in FIG. 4) by the setting program 35 of the document storage application 23. In the setting, since there is a setting for performing normal document registration without executing any security mode in addition to security mode 1 and security mode 2, which mode is set in step S206. Confirm. If the mode is for normal document registration, the process proceeds to step S216. If the security mode is specified, the process proceeds to step S207.

  In step S207, the document is subjected to OCR (Optical Character Reader) processing to create character string information. Since OCR (optical character recognition) is a well-known technique that has already been generalized, its detailed description is omitted, but simply speaking, it means converting a character image into text data.

   In step S208, word information is created from the character string information created in step S207. The creation of word information is also a general known technique and will not be described in detail. This technique is generally used for kana-kanji conversion processing for recognizing a word from a sentence composed of hiragana and converting a kanji-convertible word into kanji. In this embodiment, the word ( Recognize and extract nouns), and use applied technology that lists them as word information. The concept of creating character string information from an image document and further creating word information is shown in FIG.

  FIG. 7 is a diagram illustrating an example of an image document (A), character string information (B), and word information (C). That is, the character string information (B) is extracted from the image document (A) by OCR (P4 in FIG. 8), and further word analysis is performed by determining the area of word analysis or block selection (P5 in FIG. 8). Information (C) is generated and temporarily stored in the storage area of the document registration system 4 in the form of a word information list.

  In step S209, it is determined whether or not the character string picked up in the word information list includes the keyword set in step S107 in FIG. Since the keyword is stored in association with the cabinet / folder of the document management system 2, the document storage application 23 is based on the destination specified by the multifunction device 1 and is the document management system 2 that is the final document registration destination. And the keyword stored in association with the cabinet folder is read out. Then, the read keyword is compared with the word in the word information list for each keyword one by one to determine whether or not the same word exists (P6 in FIG. 8).

  If the keyword is included in the word information list in step S210, the process proceeds to step S211. If the keyword is not included in the word information list, the process proceeds to step S216.

  In step S211, it is determined whether the security mode is security mode 1 or security mode 2. The security mode has been described in the description of step S108 in FIG. If the security mode 2 is set, the process proceeds to step S215. If the security mode 1 is set, the process proceeds to step S212.

  In step S212, an e-mail reflecting the contents of the security mode 1 is transmitted to the administrator of the document registration system 4. As described above, the security mode 1 notifies the administrator of the document registration system 4 by electronic mail without registering the document in the document management system 2. This will be described with reference to FIG.

  That is, in the security mode 1, the document is not registered in the document management system 2, but temporarily stored in the document registration system 4 (P3), and the fact that the document is temporarily stored and the storage location of the document are e-mails. (P10), the administrator of the document registration system 4 is notified.

  In the process of security mode 1, document reading (P8) and registration process (P9) are not performed, thereby ensuring security.

  Returning to FIG. 6, in step S213, the document that is no longer registered in the document management system 2 is temporarily stored (P3 in FIG. 8). Here, for convenience of explanation, it is shown that the document is temporarily saved. However, actually, the document received from the multifunction device 1 is already saved under the management of the document storage application 23.

  As a function of the document storage application 23, for example, when the document registration in the document management system 2 fails, the administrator of the document registration system 4 is notified of this (P10 in FIG. 8). Upon receiving the notification, the administrator of the document registration system 4 can perform error document recovery processing by issuing a manual command for starting re-registration processing for an unregistered document managed and stored by the document storage application 23. For this reason, in the process in the security mode 1, when an e-mail is sent to the administrator of the document registration system 4, the administrator of the document registration system 4 subsequently performs a recovery operation. By doing so, the function of the document storage application 23 for registering a document in the document storage system 2 is not impaired. In other words, security can be improved by entrusting the operation of the recovery process to the administrator of the document registration system 4.

  In step S214, it is determined whether or not the processing of the entire document storage application 23 is to be terminated. When the process ends, the process proceeds to step S220, processing necessary for ending the application, such as saving the operation state, is performed, and the operation as a program is ended. If not completed, the process returns to step S202 and waits for reception of a document from the multifunction machine 1.

  In step S215 in FIG. 5, the operation in the security mode 2 is performed, and the document including the keyword is registered in the document management system 2 as described in step S108 in FIG. 4 (P9 in FIG. 8). The administrator of the document registration system 4 is notified by e-mail that the document including the keyword is registered in the document management system 2 (P10 in FIG. 8).

  As keywords, character strings and words related to confidential information and the like are registered. Therefore, when a document including such a keyword is registered in the document management system 2, confidential information may be leaked to the outside. By notifying the administrator of the document registration system 4 by e-mail that the document including the keyword is registered in the document management system 2, the administrator can be alerted and security can be enhanced.

  In step S216, the document is registered in the document management system 2 (P9 in FIG. 8). If it is determined in step S206 that the mode for normal document registration (no security mode) is set, this step S216 is also executed. In this case, however, step S215 is not executed, so only mere document registration is executed. It will be.

  In step S217, it is determined whether document registration in the document management system 2 has succeeded or failed. If the document storage is successful, the process advances to step S218 to notify the administrator of the document registration system 4 of the success by e-mail. If unsuccessful, the process proceeds to step S219, and the administrator of the document registration system 4 is notified by e-mail of the failure. These e-mail notifications in step S218 and step S219 are executed as part of a normal document registration process that is not related to the security mode process.

  After execution of step S218 and step S219, the process proceeds to step S214 in FIG.

  As described above, in the document registration system 4 according to the present embodiment, a document including confidential information (keywords) is not unconditionally transmitted to and stored (registered) in the external document management system 2. Confidential information can be prevented from leaking and security can be ensured. Even when a document including confidential information is transmitted and stored (registered) to the document management system 2, the administrator of the document registration system 4 is notified that the document including confidential information has been transmitted to the document management system 2. The administrator can grasp and confirm the document registration status of documents including confidential information, and can ensure security.

  In the above embodiment, the document registration system 4 evaluates the validity of document registration in the cabinet / folder of the document management system 2 by extracting character information on the image document and comparing it with keywords. This strengthens the security of document registration in the document management system 2. Also, the security mode 1 and the security mode 2 are set, and any mode can be executed in step S211 of FIG. By the way, as for the flow of the two processes after branching in step S211, various applications can be considered, and it goes without saying that both applications are within the scope of the present invention.

  Further, in the above embodiment, the document registration system 4 receives image data or facsimile received image data obtained by reading a paper document by the scanner of the multifunction device 1 and performs character recognition by OCR. Although the character string is obtained, the present invention can be applied even when the document registration system 4 receives the text data from the beginning.
