  When the user authentication passes, the personal computer apparatus PC and the network compatible MFP FX issue a document distribution request to the document distribution apparatus DS, and when the user authentication fails. The personal computer device PC and the network-compatible MFP FX display a message to that effect and do not issue a document distribution request to the document distribution device DS.

  FIG. 5 shows an example of distribution prohibition condition information stored in the document distribution apparatus DS.

  This distribution prohibition condition information is composed of three categories of “target”, “prohibited item”, and “value”. The contents of “target” consist of two items, “distribution setting information” or “distribution data”, and the contents of “prohibited items” are “distribution means”, “distribution destination”, “additional processing” (the distribution setting above). Information), “document size upper limit”, “document page upper limit”, “document type”, “prohibited characters”, “prohibited objects” (hereinafter, distributed data).

  Here, the distribution information transmitted from the personal computer apparatus PC and the network compatible MFP FX to the document distribution apparatus DS includes “distribution setting information” for instructing a distribution destination and “distribution data” representing the main body of the distribution document. .

  As the distribution data, the personal computer device PC uses application documents appropriately created by the personal computer device PC, for example, document data created by document creation software, table data created by spreadsheet software, and the like. It is done. Further, in the network compatible MFP FX, a facsimile document (image information) received from another group 3 facsimile machine, image data read by the scanner 5, and the like are used.

Similarly, “PDF conversion (no password)” registered in “value” indicates a case where PDF conversion is selected as an additional process at the time of distribution processing, and no password is set. ing.

  In addition, “prohibited characters” in “prohibited items” of “distributed data” prohibits distribution if the content of the distributed data includes this character (in this case, “confidential” or “print prohibited”). ". The “prohibited object” is “prohibit distribution when the content of distribution data includes this object (in this case,“ table ”)”.

  As described above, the distribution data is prohibited from being distributed when it contains contents that may lead to the leakage of personal information, which is a security problem. For example, in a customer list table created by an application such as Excel (registered trademark), “customer list” will be specified as the document type, and the data format is “table” in the first place. The distribution of such distribution data is prohibited.

  Since the other items in FIG. 5 are general matters, detailed description thereof is omitted.

  FIG. 6 shows an example of the processing of the personal computer device PC and the network compatible MFP FX in this case, that is, the device that issues a document distribution request to the document distribution device DS.

  First, the user authentication information is input to the user (process 101), the user authentication information is transmitted to the document distribution apparatus DS, and the user authentication result is received (process 102). When the document distribution device DS notifies that the user authentication has not been passed (the result of determination 103 is NO), an error is displayed (process 104), and the process of issuing the document distribution request at this time ends in error.

  Further, when the document distribution device DS notifies that the user authentication has been passed (the result of the determination 103 is YES), the user is made to input distribution setting information (process 105), and a distribution instruction is input from the user. (Process 106), a delivery document set for delivery is created (Process 107), and delivery information and delivery data are transmitted to the document delivery device DS (Process 108).

  FIG. 7 shows an example of user authentication processing performed by the document distribution apparatus DS in this case.

  First, when user authentication information is received from the personal computer device PC or the network compatible MFP FX (process 201), information for user authentication (not shown) (for example, an information group consisting of a set of a user name and a registered password). , User authentication is performed (process 202), and the authentication result is notified to the transmission source of the user authentication information (process 203).

  FIG. 8 shows an example of a distribution prohibition determination process performed by the document distribution apparatus DS in this case.

  First, when distribution information and distribution data are received from the personal computer apparatus PC or the network compatible MFP FX (process 301), the contents of the received distribution information and distribution data are analyzed (process 302), and the above-described distribution prohibition condition information is obtained. With reference to this, it is checked whether any of the distribution prohibition conditions is satisfied (processing 303).

  FIG. 9 shows another example of processing of the personal computer device PC and the network compatible MFP FX, that is, the device that issues a document distribution request to the document distribution device DS in this case.

  First, the user authentication information is input to the user (process 401), the user authentication information is transmitted to the document distribution apparatus DS, and the user authentication result is received (process 402). When the document distribution apparatus DS notifies that the user authentication has not been passed (the result of the determination 403 is NO), an error is displayed (process 404), and the process of issuing the document distribution request at this time ends in error.

  Further, when the document distribution apparatus DS notifies that the user authentication has been passed (the result of the determination 403 is YES), the user is made to input distribution setting information (process 405), and a distribution instruction is input from the user. (Process 406), a distribution document set for distribution is created (Process 407), and distribution information and distribution data are transmitted to the document distribution device DS (Process 408).

  Next, it is checked whether or not erroneous delivery has been notified from the document delivery device DS (decision 409). When the result of determination 409 is YES, an error is given to the user that the designated document delivery request is erroneous delivery. Display (step 410), and the operation at this time is terminated.

  FIG. 10 shows an example of a distribution operation performed by the document distribution apparatus DS in this case.

  First, when distribution information and distribution data are received from the personal computer device PC or the network compatible MFP FX (process 501), the contents of the received distribution information and distribution data are analyzed (process 502), and the above-mentioned distribution prohibition condition information is obtained. With reference to this, it is checked whether any of the distribution prohibition conditions is satisfied (process 503).

  Then, it is determined by processing 503 that any one of the distribution prohibition conditions is satisfied, and it is checked whether or not the distribution is erroneous (determination 504). When the result of determination 504 is NO, distribution data is distributed according to the distribution information received at this time (process 505).

  Further, when the result of determination 504 is YES, since an erroneous delivery has been detected, a delivery stop process is performed (process 506), and log information about the delivery stop at that time is created and saved (process 507). Then, the transmission source of the distribution information / distribution data at that time is notified that the erroneous distribution has been detected (process 508).

  In this way, in this embodiment, the document distribution apparatus DS refers to the distribution prohibition condition information for the document distribution request specified by the user of the personal computer apparatus PC and the network compatible MFP FX, and receives the received distribution information / Check whether the distribution data satisfies any of the distribution prohibition conditions, and if so, the personal computer device PC and the network compatible MFP FX are notified of erroneous distribution without performing distribution. It is advantageous in terms of security.

  By the way, the document distribution apparatus DS includes a user list table as shown in FIG. 11A and a group member table as shown in FIG. 11B as information to be referred to at the time of user authentication. In this case, the group member table includes three groups, “Administrator” representing an administrator group as a group name, “Guest Users” representing guest users, and “All Users” representing all users.

  Therefore, as shown in FIG. 12, the distribution prohibition condition information can be configured by setting application items for each user and each user group. Here, each item of the distribution prohibition condition information in FIG. 12 is the same as that shown in FIG. In addition, for the “user-specific set value”, the top item represents the user name or group name, and the column corresponding to each item following it satisfies the condition for the item with a value of “O”. Indicates that the distribution is forcibly stopped, and the item with the value “●” indicates that the user is to confirm the continuation of the distribution when the condition is satisfied, and the value is “−”. The item is not covered.

  Therefore, for example, for the user with the user name “ddd”, when the value of “distribution means” of “distribution setting information” is “shared folder”, it is determined that the distribution prohibition condition is satisfied, and “distribution” When “table” is included in “data”, a process of inquiring whether or not to continue distribution to the user is performed.

  FIG. 13 shows an example of the processing of the personal computer apparatus PC and the network compatible MFP FX in this case, that is, the apparatus that issues a document distribution request to the document distribution apparatus DS.

  First, the user authentication information is input to the user (process 601), the user authentication information is transmitted to the document distribution apparatus DS, and the user authentication result is received (process 602). When the document distribution apparatus DS notifies that the user authentication has not been passed (the result of the determination 603 is NO), an error is displayed (process 604), and the process of issuing the document distribution request at this time ends with an error.

  Further, when the document distribution device DS notifies that the user authentication has been passed (the result of the determination 603 is YES), the user is made to input distribution setting information (process 605), and a distribution instruction is input from the user. (Process 606), a distribution document set for distribution is created (Process 607), and distribution information and distribution data are transmitted to the document distribution device DS (Process 608).

  Next, it is checked whether or not the document distribution apparatus DS has instructed to confirm the continuation of distribution (decision 609). When the result of the determination 609 is YES, the user is confirmed whether or not to continue the distribution. Input is performed (process 610), and the input result of process 610 is transmitted to the document distribution apparatus DS (process 611).

  In addition, when an erroneous delivery is notified from the document delivery apparatus DS, an error is displayed to the user that the designated document delivery request is an erroneous delivery, and the operation at this time is terminated (not shown). .

  FIG. 14 shows an example of a distribution prohibition determination process performed by the document distribution apparatus DS in this case. In this case, the same process as that in FIG. 7 is applied to the user authentication process.

  First, when distribution information and distribution data are received from the personal computer device PC or the network compatible MFP FX (process 701), the contents of the received distribution information and distribution data are analyzed (process 702), and as shown in FIG. With reference to the distribution prohibition condition information, it is checked whether or not any distribution prohibition condition is satisfied for the login user at that time (process 703).

  Then, it is determined by processing 703 that any one of the distribution prohibition conditions or the distribution continuation confirmation condition is satisfied, and it is checked whether or not the distribution is erroneous (determination 704). When the result of determination 704 is NO, the distribution data is distributed according to the distribution information received at this time (process 705).

  If the result of determination 704 is YES, it is checked whether or not the distribution continuation confirmation condition is satisfied (determination 706). If the distribution prohibition condition is satisfied and the result of determination 706 is NO, an erroneous distribution has been detected, so a distribution cancellation process is performed (process 707), and log information about the distribution cancellation at that time is created. Then, the output is saved (process 708), and the transmission information / distribution data transmission source at that time is notified that the erroneous distribution has been detected (process 709).

  Further, when the result of determination 706 is YES, a command to request confirmation of distribution continuation is issued to the transmission source of distribution information / distribution data at that time (process 710). Then, when a response to the process 710 is received (process 711), it is checked whether or not it is notified that the distribution is continued (decision 712). When the result of determination 712 is YES, the process proceeds to process 705 and a distribution operation is performed. When the result of determination 712 is YES, the process proceeds to process 707 and distribution is stopped.

  By the way, for users who repeat misdelivery, it is preferable to take measures to prevent acceptance of subsequent document delivery services when the number of misdelivery reaches a certain value, for example, 10 times.

  Therefore, for example, as shown in FIG. 15A, erroneous delivery history information for storing the number of times of erroneous delivery is created for each user, and the number of times of erroneous delivery exceeding the upper limit of 10 is shown in FIG. In such a manner, processing is performed such that all the values of the items in the user column of the distribution prohibition condition information for each user are corrected to “◯”.

  Thus, thereafter, all document distribution requests operated by the user are handled as erroneous distribution.

  In the above-described embodiment, the personal computer device PC and the network compatible MFP FX are used as devices for creating a distribution document, but other appropriate information generation devices can be applied.
