The control unit 204 reads out the digitized originals stored in the original storage unit 206 to which a document ID that matches a part of the input document ID has been assigned, and outputs it to the input / output unit 202. The input / output unit 202 transmits this digitized original to the file server 50 (S605).

  The input / output unit 502 in the file server 50 receives the digitized original from the original storage server 20 and outputs it to the control unit 504. The control unit 504 outputs the digitized original and the electronic document stored in the file storage unit 506 in S602 to the difference detection unit 506. The difference detection unit 508 detects a difference between the input digitized original and the electronic document, and generates difference information representing the difference (S606). For example, when the stored electronic document is an electronic original that has been added or modified, a difference is generated between the electronic original and the electronic document, and difference information representing the difference is generated. The generated difference information is sent to the control unit 504.

  Further, the control unit 504 generates information (installation location information) indicating the installation location of the file server 50 (S606). The installation location information includes an identifier of the file server 50 and an identifier of the business office Z where the file server 50 is installed. Furthermore, the control unit 504 adds the document ID specified by the analysis in S603 to each of the difference information from the difference detection unit 508 and the generated installation location information, and outputs the information to the input / output unit 502. The input / output unit 502 transmits the difference information with the document ID added thereto and the installation location information to the trace server 10 (S607).

  On the other hand, in the trace server 10, operations similar to S410 to S412 in FIG. 11 corresponding to the above-described fourth operation are performed. That is, the input / output unit 102 in the trace server 10 receives the difference information and the installation location information transmitted from the file server 50 in S <b> 607 and outputs them to the control unit 104. The control unit 104 stores the input difference information in the trace data storage unit 108 (S608). Further, the control unit 104 evaluates the input installation location information (S609), and notifies the operator of the evaluation result by displaying the evaluation result on a monitor (not shown) or the like (S610).

  FIG. 14 is a sequence diagram showing a seventh operation of the in-company system. In the seventh operation, information on the installation location of a device that transfers a packet including an electronic document or the like is managed.

  The input / output unit 602 in the router Z76 includes an electronic document to which a document ID is assigned from a transfer source device (any one of the scanner 30, the printer 40, the file server 50, and the user PC 60), and a packet in which a transfer destination is set. Is transmitted (S701), the packet is received and output to the control unit 604. The control unit 604 specifies the transfer destination set in the input packet, and instructs the input / output unit 602 to transfer to the transfer destination. In accordance with this instruction, the input / output unit 602 transfers the received packet to a router (transfer destination router) to which a transfer destination device (not shown) is connected (S702).

  Next, the control unit 604 analyzes the document ID given to the electronic document included in the input packet (S703). Furthermore, the control unit 604 generates information (installation location information) indicating the installation location of the router Z76 (S704). The installation location information includes an identifier of the router Z76 and an identifier of the business office Z where the router Z76 is installed. Then, the control unit 504 adds the document ID specified by the analysis in S703 to the generated installation location information and outputs the information to the input / output unit 602. The input / output unit 602 transmits the installation location information to which the document ID is added to the trace server 10 (S705).

  The input / output unit 102 in the trace server 10 receives the installation location information transmitted from the router Z76 and outputs it to the control unit 104. The control unit 104 evaluates the input installation location information (S706), and notifies the operator of the evaluation result by displaying the evaluation result on a monitor (not shown) or the like (S707).

  As described above, in the in-company system of the present embodiment, the scanner 30, printer 40, file server 50, and router Z76 constituting the information processing apparatus are processed information obtained by processing the electronic original as original information. When the new electronic document is obtained, an identifier including the identifier given to the digitized original is given to the new electronic document, and further, the identifier and information on the location where the new electronic document is obtained are added. These are transmitted to the trace server 10 and managed by the trace server 10. Accordingly, it is possible to obtain information on the processing location after associating the digitized original with a new electronic document, and to manage the information processing process.

  Further, the scanner 30, the printer 40, and the file server 50 constituting the information processing apparatus detect the difference between the digitized original and the new electronic document, and the trace server together with the identifier assigned to the new electronic document. 10 are managed by the trace server 10. Accordingly, it is possible to manage the difference by associating the digitized original and the new electronic document.

  As described above, according to the information processing apparatus, information management apparatus, information processing method, information management method, information processing program, and information management program according to the present invention, it is possible to manage the information processing process. It is useful as an information processing apparatus.
