To.

  The user management server 30 compares the received user ID and password with the data in the document creation user database 305. If there is no matching record, the process returns to step A3 and the user ID and password input screen is displayed again on the terminal device 10. Is transmitted (step A6). When the ID and the password match, the user management server 30 transmits the document registration screen managed by the screen information management unit 303 to the terminal device 10 via the network 100 (step A7). An example of this document registration screen is shown in FIG. As illustrated in FIG. 12, the document registration screen includes a user name of a document creation user, a user ID, selectable approval user information, and an access path designation field for an approval target document in the terminal device 10. When creating this screen, the screen information management unit 303 of the user management server 30 refers to the approval user DB 306 (FIG. 6) based on the approval user ID registered in advance in the document creation user DB 305 (FIG. 5). Approve user names corresponding to the IDs are extracted and listed on the document registration screen. Therefore, if a plurality of approval user IDs are registered in the document creation user DB 305 in advance, there will be a plurality of approval users listed on the document registration screen in FIG. When the document creation user designates the document and the approval user on this screen and presses the transmission button, the screen posting information and the approval target document are transmitted to the document management server 40 via the network 100 (step A8).

  When receiving the document and other information, the document management server 40 first assigns a unique document number (step A9). Next, a new record is created in the document information management DV 406 shown in FIG. 8, and the document creation user ID included in the received information, the designated approval user ID, the assigned document number, and the file name are associated with each other. (Step A10). Here, at the time of creating a record, the approval / disapproval information column is “unapproved”, and the approval date and time is blank. Next, the document management server 40 transmits the document number and the designated approval user ID to the user management server 30 via the network 100 (step A11). Further, a document name or the like may be transmitted, and the received information is stored in a storage area (not shown) of the user management server 30.

  The user management server 30 refers to the approved user DB 306 based on the received approved user ID, extracts an email address, and describes an address for connecting to the user management server 30 managed by the screen information management unit 303. Is sent to the mobile phone 20 of the corresponding authorized user. Here, the server 30 prepares an access page for each document, and the approval user receives an approval request including the approval user ID, the document number, or information obtained by encoding these in the address described in the document mail. You may comprise so that only a document can be accessed.

  This mail is received by the approval user's mobile phone 20, and the approval user confirms the approval request mail and makes a connection request to the user management server 30 from the address described (step A13). In this case, it is preferable that the mail application of the mobile phone 20 has a hyperlink function, and a connection request is transmitted when a network address described in the mail is selected. Upon receiving a connection request from the mobile phone 20, the user management server 30 returns an approved user login screen managed by the screen information management unit 303 via the network 100 (step A14). An example of this authorized user login screen is shown in FIG. When the approved user operates the information input unit 203 of the mobile phone 20 to input the user ID and password on the screen and presses the send button, the information is transmitted to the user management server 30 (step A15). At this time, the model information of the mobile phone 20 is also included in the transmission information. The model information of the mobile phone may be configured to be automatically included in the transmission information, or may be input or selected by the authorized user in the model information input field. Further, the cellular phone 20 is configured to automatically delete the user ID and password from the memory after the login information is transmitted, thereby preventing subsequent unauthorized access (step A16).

  The user management server 30 refers to the approved user database 306 and compares the received ID and password of the approved user with the record (step A17). If there is no matching user information as a result of this comparison, the process returns to step A14 and the login screen is transmitted to the mobile phone 20 again. If there is matching user information, the process proceeds to step A18.

  In step A18, the user management server 30 transmits a document selection screen (not shown) managed by the screen information management unit 303 to the mobile phone 20 (step A18). On the document selection screen, the document number received from the document management server 40 in step A11 is posted, and the approval user can select it. In this case, if there are a plurality of documents waiting for approval at the time of access by the approval user, a plurality of document numbers and document names are displayed, and the user can select one of the documents. Note that information such as the title of the document may be notified in advance from the document management server 40 to the user management server 30 in step A11, and the information may be listed on the document selection screen.

  The approval user operates the mobile phone 20 to transmit information specifying the document to be approved and the model information of the mobile phone 20 to the document management server 40 via the network 100 (step A19). The document selection screen is configured so that, for example, one or more documents can be selected with a radio button that can be selected and input, and the document management server 40 is notified of the document number of the corresponding document by the selection. The document management server 40 extracts the document specified by the document conversion unit 404 from the storage area based on the received document number and the model information of the mobile phone 20, and the file format / size suitable for the browser of the mobile phone 20 (Step A21). That is, for example, the model name is notified from the mobile phone 20, and the document management server 40 registers a file format, display screen size, and resolution information that can be handled by each mobile phone in advance from the model name (not shown). This table is referenced using the notified model name as a key, and the document information management database 406 is referred to the document information management database 406 based on the notified document number, and the document conversion is performed. A necessary file conversion application is started in the unit 404 to change the document into a format (for example, HTML) and a size suitable for the browser of the mobile phone 20. For example, model A has a screen size of 2.5 inches and a resolution of 480 × 690 dpi, and model B has a screen size of 2.1 inches and a resolution of 240 × 345 dpi, and is converted into a suitable document based on such information. The

  The document management server 40 transmits the converted document and the approval / disapproval selection screen to the mobile phone 20 via the network 100 (step A22). An example of this approval / disapproval selection screen is shown in FIG. The mobile phone 20 displays the received document on the screen, and the approved user confirms the content (step A23). Since the document is converted into a format (HTML or the like) that can be displayed on the browser of the mobile phone 20, it can be displayed without depending on the application used when creating the document. Thereafter, when approval / disapproval is selected on the registration screen as shown in FIG. 14 and any button is pressed, the information is notified to the user management server 30 (step A24). This notification includes information identifying the document such as a document number.

  The user management server 30 that has received the notification from the mobile phone 20 transmits the information to the document management server 40 via the network 100 when the content is approved (step A27). If the document is unapproved, an e-mail with content indicating that the document is unapproved is created and transmitted to the e-mail address of the terminal device 10 of the document creating user via the network 100 (step A26). In this case, the user management server 30 refers to the document management server 40 for the mail address of the user who created the document, using the document number notified from the mobile phone 20 of the authorized user as a key. In another embodiment, the approval / disapproval information by the approval user may be transmitted directly to the document management server 40.

  The document management server 40 that has received the approval approval information registers the approval approval / disapproval information and the date / time of the notification in the document information management database 406. Also, the document file is extracted from the notified document number, the document conversion unit 404 converts the document into a display format such as a print image, and overwrites and saves it in the storage area (step A29). This conversion prevents subsequent data tampering by a third party. Although not explicitly shown in FIG. 10, the approval / disapproval information by the approval user is directly transmitted to the document management server, and the document management server 40 stores information such as approval / disapproval information and approval date / time in the DBs 405 and 406 based on the information. It may be registered.

  Thereafter, the document management server 40 transmits the document number, the document creation user ID, the approval date / time, and the information of the approver for database update to the user management server 30 (step A30), and transmitted to the mobile phone of the approved user earlier. The document file converted into a format that can be displayed on the mobile phone is erased from the storage area (step A31). The user management server 30 refers to the document creation user database 305 from the notified creation user ID, extracts the email address of the terminal device 10 of the document creation user, and creates a mail indicating that the document can be approved. Transmit (step A32). The terminal device 10 displays the received approval / disapproval information (step A33). FIG. 15 is a diagram showing an example of this screen. As shown in the figure, a screen in which an approval mark is pressed in the approval column is displayed on the terminal device 10. Here, the information of the approver and the date and time of approval is transferred from the notification information from the document management terminal 40.

  Although one embodiment of the present invention has been described in detail above, the present invention is not limited to the configuration and operation of the above embodiment, and various other modifications can be added. For example, in the above embodiment, the user management server 30 and the document management server 40 are configured separately, but this can be configured as a single server as long as each function described above is realized. When the mobile phone 20 notifies the document management server 40 of the model information, the mobile phone 20 notifies the document management server 40 not only of the model name but also information such as the file format and screen size that can be handled by the terminal itself. You may comprise as follows. Further, when the approved user completes the confirmation of the document content on the mobile phone 20, the document file in the mobile phone may be automatically deleted from the memory.

  As described above, according to the present invention, since the content confirmation and approval work of the document is realized using the mobile phone owned by the user having the authorization authority, even if the authorized user is out of the office, Approval work can be carried out quickly. In addition, since it is sent to the approved user's mobile phone after being converted into a display suitable for the mobile phone and a format (HTML, etc.) that can be displayed by a browser, the contents are checked on the mobile phone without depending on the application that created the document. be able to. In addition, since the ID and password when accessing the server from each terminal are automatically deleted immediately, it is possible to prevent an urgent login or unauthorized viewing by a third party.
