The best mode for carrying out the present invention will be described with reference to the drawings.
FIG. 1 is a network configuration diagram showing this embodiment.
In the information processing system, a plurality of client PCs 101 to 103 that output documents and document information, a document storage device 110 that stores documents and document information, and a document processing device 111 are configured by, for example, a LAN (Local Area Network). They are connected via a network 104. The document storage device 110 is, for example, a print server, the document processing device 111 is, for example, a printer, and the document stored in the document storage device 110 is printed by the document processing device 111.

FIG. 2 is a diagram illustrating a document and document information generated by the client PCs 101 to 103.
A document 201 is a set of data related to contents processed by the document processing apparatus 111. For example, when the document processing apparatus 111 is a printer, it is a drawing command or compressed image data.
On the other hand, the document information 202 is information related to a document such as a document name (document name) and information (document owner name) indicating a user who outputs the document from the client PC.

FIG. 3 is a diagram illustrating the configuration of the document storage device 110.
The CPU 301 controls the entire document storage device 110. The document storage device 110 is connected to the network 104 via the network interface 302. The storage unit 303 stores a program for controlling the document storage device 110 and the like. The document storage unit 304 stores documents received from the client PCs 101 to 103 via the network interface 202 together with the document ID.

The document information storage unit 305 stores document information received from the client PCs 101 to 103 via the network interface 202 together with the document ID. The document ID is an identifier for identifying a document or document information, and a numerical value or the like is used. Hereinafter, for example, a document stored in the document storage unit 304 together with the document ID “001” (provided with the document ID “001”) is referred to as “document ID“ 001 ””, and the document ID “001” is the example. The assigned document information is referred to as “document information of document ID“ 001 ””.
Note that the same document ID is associated with the document and the document information by assigning the same document ID to the document and the document information.

  Information stored in the document information database 306 will be described later. The user information database 307 stores a user and an information notification destination such as an email address in association with each other. The output instruction unit 308 issues an instruction to output a document and document information to the document processing apparatus 111. Specifically, the output instruction unit 308 receives an output instruction from an IC card reader or the like, and receives the output instruction data from the received output instruction data. Can be specified.

FIG. 4 is a flowchart showing the flow of processing performed by the CPU 301 when the document storage device 110 stores documents and document information.
The CPU 301 starts processing when a document and document information are transmitted from the client PCs 101 to 103 to the document storage device 110. For example, when a user issues a print instruction from an application (printer driver) running on the client PC 101, the application generates document and document information corresponding to the document, and the document and document information are sent to the document storage apparatus 110 to the client PCs 101 to 101. 103.
As a specific example, when a case where the user “A” issues a print instruction for a document “customer list.txt” from an application, a drawing command representing the contents of the “customer list.txt” document is generated as a document. On the other hand, as the document information, information that the document name is “customer list.txt” and the document owner name is “A” is generated by the application. Then, both the document and the document information are transmitted from the client PCs 101 to 103 to the document storage device 110.

  The document storage device 110 receives a document and document information corresponding to the document via the network interface 302 (S401). The document storage apparatus 110 extracts the document and the document information separately from the document and document information received in step S401 (S402). The document storage device 110 generates a document ID, the document is stored in the document storage unit 304 together with the document ID, and the document information is stored in the document information storage unit 305 together with the document ID (S403). For example, when the document storage device 110 generates the document ID “001”, the document with the document ID “001” is stored in the document storage unit 304 and the document information with the document ID “001” is stored in the document information storage unit 305. Is done.

  Subsequently, new document information is generated in the document storage device 110 (S404). This new document information has the same items (document name, document owner name, etc.) as the document information output from the client PC. For example, the document information with the document name “271828.doc” and the document owner name “*” is included. Generated. At this time, the document name is generated using a random number or the like.

  Document information output from the client PC (hereinafter sometimes referred to as “pre-replacement document information”) and new document information generated by the document storage device 110 (hereinafter also referred to as “replacement document information”). FIG. 9 shows a contrast. In the document information before replacement, the document name is “customer list.txt”, whereas in the document information after replacement, “271828.doc”, and in the document information before replacement, the document owner name is “A”. On the other hand, the replacement document information is “*”.

  Subsequently, in the document storage device 110, the document information stored in the document information storage unit 304 is replaced with the document information generated in step S403 (S405). That is, the document information of the document ID “001” stored in the document information storage unit 304 is changed from the document name “customer list.txt” and the document owner name “A” to the document name “271828.doc” and the document owner name “ * ". At this time, as shown in FIG. 5, the document ID, the document name before replacement “customer list.txt”, and the document owner name “A” before replacement are stored in the document information database 306 in association with each other.

  In the document storage device 110, the information notification destination of the user “A” associated with the document owner name “A” before replacement is referred to from the user information database 307, and the user “A” is received from the document storage device 110 via the network interface 302. ”Is notified of the document name“ customer list.txt ”before replacement and the document name“ 271828.doc ”after replacement (S406). For example, a character string “Customer list.txt” is displayed as “271828.doc” is notified to the information notification destination of the user “A”. Information notified to the information notification destination is not limited to character information.

FIG. 6 is a flowchart showing the flow of processing performed by the CPU 301 when the document storage device 110 outputs document information to the client PCs 101 to 103.
The document storage device 110 receives a document information output instruction from the client PCs 101 to 103 via the network interface 302 (S601). Next, the document storage device 110 gives a document information output instruction to the document information stored in the document information storage unit 305 together with information (state information) indicating the current state of the document related to the document information. The output is transmitted to the client PC (S602). The status information includes “processing” indicating that the document is being processed in the document processing apparatus 111, “pause” where processing of the document is temporarily stopped, and the like.

As a result of step S602, information as shown in FIG. 7 is displayed on the client PC.
That is, the document name and the document owner name after being replaced in step S405 are displayed together with the state of the document. Since only pseudo document information that is different from the document information output from the client PC is displayed on the screen, the user other than “A” who viewed this display screen can see what name and what document the document storage device has. I do not know if it is stored in 110. However, since the user “A” can see that his document “customer list.txt” is displayed as “271828.doc” from the information notified from the document storage device 110 in step S406, It is possible to determine what kind of document state it is.

FIG. 8 is a flowchart showing the flow of processing performed by the CPU 301 when the document storage device 110 outputs a document and document information to the document processing device 111.
When an output instruction is issued by the output instruction unit 308 of the document storage device 110, the user who has issued the output instruction from the document storage device 110 is identified (S801). The document ID of the document for which the user is the document owner is specified from the document information database 306 (S802). For example, when the user “A” gives an output instruction, the document ID “001” is specified from the contents of the document information database 306 shown in FIG. In the document storage device 110, the document with the document ID specified in step S802 is specified using the document storage unit 304 (S803). Then, the document specified in S803 and the document information corresponding to the document ID stored in the document information database 306 are output to the document processing apparatus 111 (S804). That is, together with the document, the document information before being replaced in step S405 is output to the document processing apparatus 111. For example, instead of the document “271828.doc” and the document owner name “*” stored in the document information storage unit 204, the document name “customer list.txt” and the document owner name “A” are used as the document information. 111 is output. In this way, by returning the document information to the state before replacement and outputting it to the document processing apparatus 111, when the document processing apparatus 111 records the document information about the processed document as a history, the history is correct. Document information (before replacement) is recorded.

In addition to the above embodiments, the present invention includes various modifications as follows.
In the above-described embodiment, the client PCs 101 to 103, the document storage device 110, the document processing device 111, and the client PC are connected via the common network 104. However, another configuration may be used. For example, the present invention can also be applied to a configuration in which the document storage device 110 and the document processing device 111 are connected via another network, but the client PCs 101 to 103 and the document processing device 111 are not connected at all. Further, the document storage device 110 and the document processing device 111 may be integrated as one device.

  In the above embodiment, the user information database 307 is used to refer to the information notification destination. However, another configuration may be used. For example, when a document and document information are output from the client PCs 101 to 103 to the document storage device 110, an information notification destination may be output to the document storage device 110. In this embodiment, the user information database 307 is not necessary.

  In the above embodiment, in order to associate the document with the document information, the same numerical value is assigned as an identifier (document ID) to the document information related to the document, and the document storage unit 304 or the document information storage unit 305 is assigned. However, another configuration may be used. For example, the document is stored in the document storage unit 304 without being assigned an identifier, while the document information is stored in the document storage unit (specifically, a part of the document storage unit 304 is associated with a numerical value such as “001”). The pointer may be stored in the document information storage unit 305. Even in such a configuration, specific document information can be identified from a plurality of document information stored in the document information storage unit 305, and a document related to the document information can be identified.

  Further, in the above embodiment, random numbers or the like are used when generating new document information in step S404. However, any configuration can be used as long as document information different from the document information output from the client PCs 101 to 103 can be generated. There may be. Furthermore, it is desirable that the document information be different from other post-replacement document information already stored in the document information storage unit 305.

  In the above embodiment, the document information stored in the document information storage unit 304 is replaced with the document information generated in step S404 in step S405. However, another configuration may be used. For example, the document information stored in the document information storage unit 304 may be output from the client PC, and the document information generated in step S404 may be stored in a part different from the document information storage unit 304. Even in this case, when the document storage device 110 receives a document information output instruction from the client PC (S601), the document storage device 110 stores the document information generated in step S404 to the client PC. The confidentiality of the document information can be improved.

  In the above embodiment, the output instruction unit 308 is provided in the document storage device 110. However, another device such as the document processing device 111 may be provided with the output instruction unit.

  In the above embodiment, the document and the document information are output from the document storage apparatus 110 to the document processing apparatus 111 only after the output instruction is issued by the output instruction unit 308. However, another configuration may be used. For example, if a document and document information are stored in the document storage device 110 for a predetermined time or longer, the document may be automatically output to the document processing device 111. In such a configuration, the output instruction unit is not necessary.

  In the above embodiment, the document information output from the document storage device 110 to the document processing device 111 is the information before replacement, but may be information after replacement. Even with this configuration, the confidentiality of the document information stored in the document storage device can be improved.

  Further, in the above-described embodiment, the description has been given on the assumption that there are a plurality of client PCs. However, a single client PC may be used.

  The present invention includes a program for controlling the apparatus or system as described above. As recording media for supplying this program, there are a hard disk, a CD-ROM, a DVD-ROM, and the like.
