Description

The present invention relates to an electronic document that automatically performs communication processing between electronic documents, and more particularly to an electronic document system that facilitates communication processing between documents by determining a communication partner according to the contents of the electronic document .

  In recent years, with the development of computers and the spread of the Internet, electronic documents expressed in digital information have become widespread. Electronic documents are useful because they can share document information with multiple people at remote locations by using communication technology.

  An electronic document is usually processed by a program that runs on a computer called an application program, and is similarly processed by an application program when document information is communicated between a plurality of computers. Therefore, when handling an electronic document, the user needs to install these application programs in the computer in advance. For this reason, if an application program capable of processing the same electronic document is not installed on all computers used as communication processing terminals, the document information communication processing cannot be executed between the computers, and the document information is shared. Can not do it.

  In addition to the communication processing, the user cannot view the electronic document unless an application program that interprets the format of the electronic document and displays it on the screen is installed on the computer that is the communication terminal. There is also.

  As one method for solving this problem, the present applicant discloses a technique such as an encapsulated document structure in the specification of Japanese Patent Application No. 2001-198818.

  The encapsulated document structure is an electronic document structure in which a content file representing a document structure or content and an operation program file for operating the content file are encapsulated. Since the operation program in the encapsulated document file interprets the content file as electronic document information and executes the operation process, the document file having the encapsulated document structure can be executed without an external application program. .

  By encapsulating an operation program for processing electronic document information by adopting these technologies, it is possible to communicate and display electronic document information between computers in different environments.

  Specific examples of conventional techniques include those described in the following patent documents.

  In the above-described conventional electronic document processing, if document ID information is not added at the time of creating an electronic document, the electronic document to be communicated cannot be specified from the document ID information at the time of communication processing. The problem that it is not possible arises.

  In addition, when the document ID information is added to the document, if the document management server or the like cannot be used, the document ID information used for communication processing cannot be managed centrally. Even if it exists, the same document ID information may be assigned.

  In addition, electronic documents are easy to edit, unlike paper documents, so while electronic documents are used, the document contents are often edited to update the document contents. If the same document ID information is assigned to each other and communication processing is executed between computers, the electronic document before editing and the electronic document after editing cannot be distinguished. For this reason, during communication processing, document content information that is not intended by the transmission side is likely to cause problems such as manipulation (modification processing for pointers and document content information) and modification on the reception side.

  As a countermeasure, the document ID information can be changed when the electronic document is edited. However, if the document ID information is changed each time an editing operation is performed, a large amount of unnecessary document ID information is created. There arises a problem that management of information becomes complicated. In addition, when document ID information is not centrally managed by a server or the like, when document editing is performed on a plurality of computers, the same document ID information is obtained even if the electronic documents have different editing contents. The problem of being assigned arises.

  Considering each of the conventional techniques described above, first, in Japanese Patent Application Laid-Open No. 2002-41503, the feature amount of the external character information in the document is calculated and stored in the server. Thus, on the client computer side, it is possible to search for a desired document using the feature value, but the feature value is used only for document search in the server, and communication processing is performed between the documents. It is not considered to be used as identification information. Therefore, there is a problem in that computers having electronic documents having the same content cannot be automatically communicated with each other.

  In the device described in Patent Document 2 (Japanese Patent Application Laid-Open No. 2002-175311), a feature amount is added to video information as content information by digital watermark technology, and the video information and the feature amount are integrated to obtain video information. However, the feature amount is used only for video search in the server, and the use of identification information for communication processing between videos or documents is considered. Therefore, there is a problem that computers having the same content or video or electronic document cannot be automatically communicated with each other. Further, if a feature amount is included in the header portion of the video information, the feature amount information in the header portion may be lost when the image format of the video information is changed.

  In the device described in Patent Document 3 (Japanese Patent Laid-Open No. 2002-183704), access control at the time of communication is possible by calculating a feature amount from biometric information and performing personal authentication, but from content information such as a document. Since the calculation of the feature amount is not taken into consideration, there is a problem in that it is not possible to automatically perform communication processing between computers having electronic documents having the same contents unless user information is managed at the time of communication processing. is there.

  In the device described in Patent Document 4 (Japanese Patent Application Laid-Open No. 2003-242033), it is possible to reduce operations such as setting and management of user IDs, passwords, and the like by using feature amounts as access control for file sharing. However, the feature amount and the file must be registered in the file management server, and registration work is required. Of course, the file sharing system cannot be used without a file management server.

  In the document described in Patent Document 5 (Japanese Patent Application Laid-Open No. 2000-48011), a document can be updated without transmitting unnecessary data by specifying an edited part and transmitting only the part. Since only the document information update processing method is considered, it is not considered to use the feature information as identification information for communication processing between documents. Cannot be automatically communicated.

  In the device described in Patent Document 6 (Japanese Patent Laid-Open No. 2002-197101), an electronic document is updated by adding document ID information to the electronic document and managing the update history of the electronic document with a document management system. In this case, a paper document with updated document contents can be printed out from the copier, but a document management system having a server that centrally manages document ID information is required, and an electronic document is updated. Since the document ID information is changed each time, a large amount of unnecessary document ID information is created and management becomes complicated.

  In the document described in Patent Document 7 (Japanese Patent No. 3384016), when a document is edited in the network in the document management system, the change intention is estimated and the estimation result is calculated based on the document change intention determination rule. By displaying to the user, the contents of the document in the network can be matched, but it is not considered to add a document ID information or the like to the document to determine a computer that performs communication processing in the network. There is a problem that it is not possible to automatically perform communication processing between computers having electronic documents of contents.

  In the device described in Patent Document 8 (Japanese Patent Laid-Open No. 5-128117), it is possible to simultaneously update the same document by specifying a position for editing the document in advance from the document and editing the document. However, since it does not consider determining a computer that performs communication processing in a network by adding document ID information or the like to a document, communication processing is automatically performed between computers having the same electronic document. There is a problem that can not be.

  In the device described in Patent Document 9 (Japanese translations of PCT publication No. 2002-519790), unnecessary data is transmitted by transmitting only the objects updated at the time of collaborative document editing by assigning an identifier to each object constituting the document. However, it is not considered to add a document ID information to the document and determine the computer that performs communication processing within the network. There is a problem that communication processing cannot be performed.

  In the document described in Patent Document 10 (Japanese Patent Laid-Open No. 6-284242), smooth communication is possible by adding a document ID information to a document and determining a computer that performs communication processing in the network. Since it is not considered to change the document ID information after editing, there is a problem that the communication processing is similarly performed even when the document contents are different between the document after editing and the document before editing. Also, since no consideration is given to the method of adding document ID information, it is difficult to assign document ID information.

  In the device described in Patent Document 11 (Japanese Patent Laid-Open No. 7-66970), information leakage due to transmission of a confidential document can be prevented by the feature amount information of the confidential document. Since this is not taken into consideration, there is a problem in that communication processing between documents cannot be automatically started.

  In the document described in Patent Document 12 (Japanese Patent Application Laid-Open No. 2003-099303), document ID information that identifies the document itself is recorded in the encapsulated document file, so that the document can be used without depending on the computer environment. Therefore, smooth communication is possible by determining a computer that performs communication processing in the network. However, since it is not considered to change the document ID information after editing the document, even when the document contents are different between the document after editing and the document before editing, a problem that communication processing is similarly performed may occur. Further, it is difficult to assign document ID information.

  In the document described in Patent Document 13 (Japanese Patent Application Laid-Open No. 2004-102627), the genotype ID information in which the ID number is genetically mutated every time the document editing process is executed is added to the document after editing. Although it is possible to perform communication processing by distinguishing the previous document, if document ID information is mutated every time editing is performed, there is a problem that a large amount of unnecessary document ID information is created. Further, if document ID information is not centrally managed by a server or the like, when document editing is performed by a plurality of computers, there is a possibility that the same document ID information may be allocated even for electronic documents with different editing contents. is there. Furthermore, since no consideration is given to the method of adding document ID information, it is difficult to assign document ID information.

The present invention has been made in order to solve the above-described conventional problems, and a computer to be a communication destination can be provided even in an environment where use of a server or the like that centrally manages document information is restricted. An electronic document system capable of calculating document specifying information for specifying and automatically processing electronic documents having the same document contents without performing communication processing between electronic documents having different document contents. It is.

  A first object of the present invention is an electronic document processing that automatically performs communication processing between computers having the same electronic document even if document identification information such as document ID information is not added to the electronic document in advance. The device is to provide an encapsulated document structure.

  A second object of the present invention is an electronic document processing apparatus that automatically performs communication processing between electronic documents having the same document specifying information, such as a server that centrally manages electronic documents cannot be used in a network. To provide an electronic document processing apparatus and an encapsulated document structure that are unlikely to assign the same document specifying information to electronic documents having different contents even under an environment.

It is an object to provide an encapsulated document structure capable of performing communication processing while distinguishing between documents.

  A fourth object of the present invention is to pre-calculate the feature amount of an electronic document at the time of editing the document and store it in the electronic document, thereby reducing the computer determination processing at the time of communication processing and speeding up the initial operation at the time of document communication It is to provide an encapsulated document structure that can be performed.

The destination is set and communication processing can be performed.

  FIG. 4 is a flowchart showing an outline of this communication process.

  First, when the user of the computer 10A presses the communication execution button of the encapsulated document file 100 (step S11), the feature amount calculation program 121 in the operation program file 120 of the encapsulated document file 100 is activated to encapsulate the document file. 100 feature amount information is calculated (step S12). The feature amount information may be calculated using only the content file information in the encapsulated document file 100, or may be calculated using the operation program file information.

  Here, the feature amount information of the encapsulated document file 100 is, for example, an electronic fingerprint for the encapsulated document file 100. As a calculation method of this feature amount information, SHA1 (Secure-Hash-Algorithm 1) and the like can be cited. In SHA1, the data block of the encapsulated document file 100 is compressed with a 20-byte sequence. As a basic characteristic of SHA1, when the encapsulated document file 100 is changed even by 1 bit, the feature amount information of the encapsulated document file 100 is also changed. Due to this characteristic, the document content of the encapsulated document file 100 and the feature amount information have a one-to-one relationship. Therefore, the same feature amount information is calculated for encapsulated document files having the same document content. On the other hand, in the case of an encapsulated document file having different document contents, a difference occurs in the feature amount information. Of course, an algorithm other than SHA1 may be used as a method for calculating the feature amount information of the encapsulated document file.

  The feature amount information of the encapsulated document file calculated by the feature amount calculation program 121 is transmitted to, for example, the broadcast address 255.255.255.255, and the feature amount information is transmitted to all computers in the network ( Step S13).

  On the other hand, the other computer side in the network 30 receives the transmitted feature amount information (step S14), and uses the feature amount comparison program 122, and the feature amount of the encapsulated document file 100 and the like in the computer. Information is calculated (step S15), and it is compared whether or not the calculated feature amount information is the same as the received feature amount information (steps S16 and S17).

  Here, the range of the encapsulated document file 100 or the like to be compared with the feature amount information may be a predetermined range for all encapsulated document files stored in the computer, or may be stored in a specific folder. It may be a predetermined range only for the encapsulated document file, or may be a predetermined range only for the encapsulated document file activated when the feature amount information is received.

  If the feature amount information is the same, the document contents of the encapsulated document file in the sending computer and the receiving computer are the same, and therefore communication processing between documents is executed on the sending computer and the receiving computer.

  That is, if there is an encapsulated document file in which the same feature amount information as the received feature amount information is calculated (Yes in step S17), the communication determination program 123 sends the communication address information of the receiving computer to the transmitting side. To the computer. 3 and 4, the computer 10D transmits communication setting information such as an IP number (IP address) to the computer 10A (step S18). If there is no encapsulated document file for which the same feature quantity information as the received feature quantity information is calculated, the communication process is terminated (step S23). In the example of FIG. 3, since the computers 10B and 10C do not have the encapsulated document file in which the same feature amount information is calculated, the communication process with these is not performed.

  The encapsulated document file of the sending computer 10A receives the communication address information of the receiving computer 10D (step S19) and stores it in the communication processing list (step S20). Thus, the communication determination program 123 can determine a computer that executes communication processing in the network 30.

  In the communication program, the communication processing is executed by transmitting the document information to be communicated to the IP address destination stored in the communication processing list (steps S21 and S22).

  Through the above processing, even for an encapsulated document file to which document ID information for specifying document information is not added in advance, communication settings are automatically made with a computer having an encapsulated document file having the same document content. Therefore, communication between documents can be realized easily. Of course, the operation program and the like in this embodiment are not limited to the encapsulated document file format, and the content file and the operation can be obtained by installing the operation program in the encapsulated document file in the computer in advance. It is also possible to apply to a normal electronic document format in which the program file is divided.

  FIG. 5 shows a typical hardware configuration of the electronic document creation apparatus 20 for creating the encapsulated document file of the present invention.

  The electronic document creation apparatus 20 reads an operation program file of an encapsulated document file, performs various controls and processes, a CPU (central processing unit) 201, a RAM (random access memory) 202, and an HDD (hard disk drive) 203. A pointing device such as a mouse, various input interfaces (hereinafter abbreviated as I / F) 204 such as a keyboard and buttons, a display 209 such as a CRT (cathode ray tube) connected via a display I / F 206, a CD -By connecting a recording device 207 such as an RW (compact disk rewritable) drive and an external I / F 208 for wired or wireless connection to an external device such as a printer or an electric communication line such as the Internet via a bus. Composed.

  The RAM 202 is used as a work area for the CPU 201 and also as a recording area for fixed information such as a plurality of operation programs for executing the operation processing in the present invention and other control programs. For example, the operation program is loaded into the RAM 202 via the recording device 207, or once stored in the HDD 203, then loaded into the RAM 202 when necessary, or loaded into the RAM 202 via an electric communication line connected to the external I / F 208. Loaded.

  The electronic document creation apparatus 20 can be easily realized by executing a program for copying the encapsulated document structure information (data encapsulating the content file / operation program file) stored in the storage medium in the hardware. .

  The encapsulated document file 100 here may be distributed in a state where the content file 110 and the operation program file 120 are encapsulated in a single file, or may be distributed in a physically divided state. However, when the encapsulated document file 100 is distributed in a physically divided state, the content information of the content file 110 and the operation program file 120 that executes the operation processing of the content information can be associated with each other. It is necessary to devise such as adding position information of the operation program file 120 to the content file 110.

  FIG. 6 shows an example of a file format in which the position information is added as attribute information such as content information in the content file 110.

  In this encapsulated document file 100, URL (uniform resource locator), which is each location information, is added to the text information 111, the image information 112, and the audio information 113 of the content file 110, and the operation program file 120 is the same. In addition, URL information is included as position information 120 a indicating the location of the feature amount calculation program 121, the feature amount comparison program 122, the communication determination program 123, and the communication program 124. The encapsulated document file 100 acquires the operation program file 120 by referring to the position information 120a, thereby causing the content information operation process to be executed.

  By using the file format of FIG. 6, even if the encapsulated document file is distributed in a physically divided state, the operation program file is executed from the position information of the content file to perform communication processing between the documents. It becomes possible to execute.

  As described above, in this embodiment, even if document identification information such as document ID information is not added to the electronic document in advance, the communication partner is determined from the feature amount calculation result, and the electronic document having the same content is determined. You can have your computers automatically communicate with each other.

(Embodiment 2)
Figure 7 is a diagram showing an example of the encapsulated document file structure according to a second embodiment of the present invention. In the following description, the same components as those in the first embodiment will be described with the same reference numerals.

  The encapsulated document file 200 shown in the figure includes a content file 210 and an operation program file 220 similar to those in the above-described embodiment, and a document specifying file 230 added in the present embodiment.

  The content file 210 stores content information indicating the document content of the encapsulated document file 100 such as text information 211, image information 212, and audio information 213. Other content information may be stored in the content file 210 as necessary.

  In the operation program file 220, a feature amount comparison program 222, a communication determination program 223, and a communication program 224 are stored. The feature amount comparison program 222 has a function for comparing whether or not the feature amount information of the own document and the feature amount information of the encapsulated document file owned by the computer in the network 30 are the same by the electronic document processing apparatus 10. It is realized. Further, the communication determination program 223 is an encapsulation in which the feature amount information is the same for a plurality of computers in the network 30 based on the execution result of the feature amount comparison program 222 by the electronic document processing apparatus 10 using a computer. A function for determining whether or not a computer has a document file is realized. The communication program 224 has a function of executing communication processing with a computer in which the feature amount information is determined to be the same by the communication determination program 223 in cooperation with the electronic document processing apparatus 10. Various operation programs such as a display program for displaying the content information 211 stored in the content file 210 and a content information update program for updating the document contents are stored in the operation program file 220 as necessary. You may do it.

  The document specifying file 230 stores feature amount information 231 of the encapsulated document file. Here, the feature amount information 231 is, for example, “gdtuihd329f9f”. The feature amount information 231 is calculated when the encapsulated document file 200 is created and the document information is stored.

  The feature amount calculation program used for calculating the feature amount information 231 may be a program stored in the encapsulated document file 200 in advance, or may be a program stored in the computer as an external program. Good. The calculation processing of the feature amount information 231 is automatically executed when the user creates and saves a document. The feature amount information 231 is a program that combines the functions of the document creation program and the feature amount calculation program. Good.

  Further, as data used for calculating the feature amount information 231, only the content file of the encapsulated document file may be used, or an operation program file may be used. When the feature amount information 231 is calculated, the previous feature amount information may not be included. The calculated feature amount information 231 is stored in the document specifying file 230 in the encapsulated document file 200. When the encapsulated document file 200 is created and saved by the above processing, the feature amount information 231 of the encapsulated document file 200 is automatically calculated and saved in the document specifying file 230. The content file 210 is the same as that in the first embodiment.

  In the operation program file 220, a feature amount comparison program 222, a communication determination program 223, and a communication program 224 are stored. Communication determination program 223 and communication program 224 are the same as communication determination program 123 and communication program 124 in the first embodiment, respectively.

  The feature amount comparison program 222 is stored by the electronic document processing apparatus 10 in the feature amount information 231 stored in the document specifying file of the document itself and in the document specifying file 230 in the encapsulated document file 200 in the computer in the network 30. A function for comparing whether or not the feature amount information is the same is realized. In addition, various operation programs such as a display program for displaying content information stored in the content file 210 and an editing program for editing document contents are stored in the operation program file 220 as necessary. Also good.

  When the editing program is stored in the operation program file 220, the feature amount information 231 of the encapsulated document file 200 is calculated when the document content information is edited and stored, and the calculated feature amount information 231 is stored in the document specifying file 230. A functional part to be saved is added to the editing program.

  FIG. 8 is a processing flowchart of a communication method using an encapsulated document file according to this embodiment.

  In the figure, when the user of the computer A presses an execution button for the communication processing of the encapsulated document file (step S31), the feature amount information 231 stored in the document specific file of the encapsulated document file is read into the RAM. (Step S32). The feature amount information 231 of the encapsulated document file read from the document specific file is transmitted to the broadcast address 255.255.255.255, and the feature amount information 231 is transmitted to all the computers in the network (step S33). ). The computer side in the network receives the transmitted feature amount information 231 (step S34), starts the feature amount comparison program, and reads the feature amount information stored in the document specific file of the encapsulated document file in the computer. (Step S35), whether or not the read feature quantity information is the same as the received feature quantity information 231 is compared as in the first embodiment (Step S36). Then, the communication determination program 223 and the communication program 224 cause communication processing to be executed in the same procedure (steps S37 to S43) as steps S17 to S23 in the first embodiment described above. That is, if the feature amount information 231 and the like are the same, the document contents of the encapsulated document file in the transmission side and reception side computers are the same. Is executed.

  If there is an encapsulated document file having the same feature quantity information 231 as the received feature quantity information 231 (Yes in step S37), the communication determination program 223 sends the communication address information of the receiving computer to the sending computer. Send to. In the example of FIG. 8, the computer 10D transmits communication setting information such as an IP number to the computer 10A (step S38). If there is no encapsulated document file having the same feature quantity information 231 as the received feature quantity information 231, the communication process is terminated (step S43).

  The encapsulated document file of the sending computer 10A receives the communication address information of the receiving computer 10D (step S39) and saves it in the communication processing list (step S40). Thus, the communication determination program 223 can determine a computer that executes communication processing in the network 30.

  In the communication program, the communication processing is executed by transmitting the document information to be communicated to the IP address destination stored in the communication processing list (steps S21 and S22).

  By executing the above communication process, the communication partner can be determined without calculating the feature amount information 231 of the encapsulated document file 200 during the communication determination process. Therefore, the communication determination processing time is reduced, and the communication process between documents is performed. It is possible to provide an encapsulated document structure capable of performing the initial operation of the above at high speed.

(Embodiment 3)
FIG. 9 is a diagram showing an example of the encapsulated document file structure according to the third embodiment of the present invention, and shows an example of the embodiment according to the first, third, and fourth aspects of the present invention.

  The encapsulated document file 300 of the present embodiment is composed of a content file 310 and an operation program file 320 similar to those in the above-described embodiment, and a document specifying file 330 added in the present embodiment. The identification file 330 stores document ID information for identifying the encapsulated document file 300 in advance.

  In the example shown in FIG. 9, document ID information 331 is stored in the document identification file 330, and the document ID information 331 is, for example, “No. 56342-00 '. The number included in the document ID information 331 is assigned when the encapsulated document file 300 is created.

  The content file 310 stores content information indicating the document content of the encapsulated document file 300 such as text information 311, image information 312, and audio information 313, as in the first embodiment.

  The operation program file 320 includes a feature amount calculation program 321, a feature amount comparison program 322, and a communication determination program that are the same as the programs included in the embodiment described above (the number at the end indicates the correspondence). 323 and a communication program 324 are stored, and a document ID change program 325 is stored.

  The feature amount calculation program 321 realizes a function of calculating feature amount information of the encapsulated document file 300 by the electronic document processing apparatus 10 using a computer. The feature amount comparison program 322 has a function of comparing whether or not the feature amount information of the own document and the feature amount information of the encapsulated document file owned by the computer in the network 30 are the same by the electronic document processing apparatus 10. It is realized.

  Further, the communication determination program 323 has an encapsulated document file having the same feature amount information for a plurality of computers in the network 30 based on the execution result of the feature amount comparison program 322 by the electronic document processing apparatus 10. An encapsulated document file that realizes a function for determining whether or not it is a computer, and that is to execute communication processing with reference to a document ID stored in the document specific file, for example, a number included in the document ID information. Is identified.

  The communication program 324 has a function of executing communication processing with a computer in which the feature amount information is determined to be the same by the communication determination program 323 in cooperation with the electronic document processing apparatus 10. Various operation programs such as a display program for displaying the content information 311 stored in the content file 310 and a content information update program for updating the document contents are stored in the operation program file 320 as necessary. can do.

  The document ID changing program 325 has a function of changing the document ID information 331 stored in the document specifying file 330 according to the comparison result of the feature amount information by the feature amount comparison program 323.

  FIG. 10 shows an example of an electronic document processing system that performs communication processing between a plurality of computers in the network 30 using the encapsulated document file of this embodiment.

  In the example shown in FIG. 4, four computers 10 </ b> A to 10 </ b> D that can function as the electronic document processing apparatus 10 are connected in the network 30. Here, the computer 10A and the computer 10D have the encapsulated document file 300 having the same document ID information 331 number (for example, “56342-00”, hereinafter also referred to as a document ID number). Further, the numbers (eg, “56342-11” and “27895-00”) of the document ID information 331 of the encapsulated document file 300 held by the computer 10B and the computer 10C are not the same.

  When communication processing is started in this situation, the communication determination program 323 executes the communication processing with reference to the document ID information 331 of the encapsulated document file 300 held by the computers 10A to 10D in the network 30, whereby the same document ID is obtained. The computer 10A and the computer 10D having the encapsulated document file 300, which is a number, can automatically set a communication partner and perform communication processing without setting the communication partner (such as setting an IP address). Become.

  FIG. 11 is a flowchart showing a processing procedure at this time.

  In the figure, when the user presses the execution button of the communication processing of the encapsulated document file 300 on the computer 10A (step S51), the document ID information stored in the document specific file is transmitted to the computers in the network (step S52). ). The computer 10D side in the network receives the transmitted document ID information (step S53) and compares it with the document ID information of the encapsulated document file in the computer (step S54). If there is no encapsulated document file 300 having the same document ID number as the document ID information 331 received by the computer 10D (No in step S55), the computer 10D ends the communication process and broadcasts from the computer 10A. A predetermined response is not made (step S61). If there is an encapsulated document file having the same document ID information as the received document ID information (Yes in step S55), the computer 10D sends communication address information such as its own IP number (IP address) to the computer 10A. Transmit (step S56).

  In the case shown in FIG. 10, the computer 10A receives the communication address information based on the encapsulated document file 300 (step S57), and stores the transmitted communication address information of the computer in the communication processing list (step S58).

  In this manner, the computer that executes communication processing in the network 30 can be determined by the communication determination program 323. Then, the communication program 324 causes the computer 10A to transmit document information to be communicated to the IP address destination stored in the communication processing list, and communication processing with the computer 10D is executed (steps S59 and S60).

  From the above processing, if the document ID information 331 is added in advance when the encapsulated document file 300 is created, the communication setting with the computer having the same encapsulated document file 300 is automatically set, so that it is easy. Inter-document communication can be realized. However, considering the usage of electronic documents, document content information is often updated by editing operations.

  FIG. 12 shows an example of the usage form of such an encapsulated document file.

  In the figure, the computer 10A creates an encapsulated document file 300 (step P1), transmits it to the computer 10D (step P2), and receives it on the computer 10D side (step P3). This is an example in which communication processing (steps P4 and P5) between documents is started in 10D.

  In this case, initially, the document content information of the encapsulated document file 300 is the same, and no trouble occurs during communication processing between documents. However, after the communication processing is completed, the document editing operation is performed only on the computer 10A side. When the document content is updated (step P6), the document content information of the encapsulated document file 300 held by the computer 10A and the computer 10D is different. Therefore, if an attempt is made to execute communication processing between documents after the editing / update, there is a possibility that information unintended by the user (information related to the update contents) is operated on the other side.

  As a solution to this, it is conceivable that the communication processing is executed by distinguishing the pre-edited and post-edited encapsulated document file 300 by changing the document ID information 331 each time the document content information is updated by the editing operation. . However, in that case, a large amount of unnecessary document ID information is created as described below, and management of the document ID information 331 becomes complicated.

  FIG. 13 shows a processing example when the communication processing is executed by changing the document ID information 331 every time the document content information is changed.

  Also in the example shown in the figure, similarly to the case of FIG. 12, after the encapsulated document file 300 first created by the computer 10A is transmitted to the computer 10D (steps P11 and P12), communication processing between documents is executed. (Steps P13 to P15).

  Then, after the communication process is completed, the document editing work is performed on the computer 10A (step P16), and the document content information of the encapsulated document file is updated (step P17). At the time of the update, the document ID information is also changed. (Step P18). This update process is executed each time a document is edited / updated (steps P19 to P24).

  Through the above processing, when performing communication processing between documents after editing, the document ID information 331 recognizes that the document contents are different before and after editing, and executes the communication processing while distinguishing both documents. It becomes possible.

  However, since the document editing operation is executed many times in normal business, if the document ID information 331 is changed each time the document content information is updated, a large amount of unnecessary document ID information is created, and the document ID information Is managing the document ID information.

  If a server or the like that centrally manages the document ID information 331 is not installed in the network 30, as shown in FIG. 14, update processing (steps P36 to 38, P41 to 43) in the respective computers 10A and 10D is performed. There is a possibility that the same document ID information (for example, document ID: 0002 illustrated in FIG. 14) is assigned even if the information is different document contents.

  15 and 16 show a processing example in such a case.

  In FIG. 15, in response to the transmission of the document ID information from the computer 10A (step S71), the computer 10D first receives the document ID information (step S72), and encapsulated document file having the same document ID information. (Step S73), and if there is an encapsulated document file having the same document ID information (Yes in step S74), the feature amount information is calculated and transmitted (steps S76 and S77). . Further, after receiving the feature amount information from the computer 10D (step S78), the computer 10A calculates the feature amount information of the encapsulated document file 300 on the own device side (step S79), and receives the calculated feature amount information and the received feature amount information. The feature amount information is compared (step S80), and if the feature amount information matches, document communication processing with the computer 10D is executed (steps S81 to S83).

  Assume that after such communication processing between documents is completed, the document contents are updated by individually performing document editing operations on the computers 10A and 10D. At this time, if there is no server or the like that centrally manages the document ID information in the network, the computer 10A and the computer 10D may be updated to the same document ID information after the document editing process as shown in FIG. In the prior art, as described above, there may be a case where communication processing that distinguishes between differences in document content information cannot be executed.

  In order to solve such a problem, in this embodiment, communication processing is performed by distinguishing document content information updated by editing processing without creating a large amount of unnecessary document ID information 331 during document editing. An encapsulated document file 300 is provided.

  FIG. 16 shows the main part of the communication method using the encapsulated document file of this embodiment as a process following the process of FIG.

  First, the communication determination program 323 searches the network 30 for a computer having the encapsulated document file 300 that is the same document ID information as the document itself (steps S71 to S73), and the same document ID information 331 in the network 30. If there is no computer having the encapsulated document file 300, communication processing between documents is terminated (steps S74 and S75), while the encapsulated document file 300 having the same document ID information 331 is held. If the computer exists, the feature amount information of the encapsulated document file is calculated using the feature amount calculation program 321 in the operation program file 320 (steps S74 and S76). Next, the calculated feature amount information is transmitted from the computer 10D to the encapsulated document file 300 of the computer 10A by the communication program 324 of the encapsulated document file 300 (step S77). When the encapsulated document file 300 of the computer 10A receives the transmitted feature amount information (step S78), the feature amount information of the encapsulated document file 300 in its own device is calculated using the feature amount calculation program (step S78). S79). Next, using the feature amount comparison program, the computer 10A matches the feature amount information transmitted from the encapsulated document file 300 of the computer 10D with the feature amount information calculated from the encapsulated document file 300 in its own device. It is determined whether or not to perform (step S80). Here, if the feature amount information matches (Yes in step S81), the document contents of the encapsulated document files of the computer 10A and the computer 10D are the same, and the documents between the computers 10A and 10D Can be executed (steps S82 and S83).

  When a document editing operation is executed on either computer, the document content information of the encapsulated document file 300 is updated, and the feature amount information becomes different. That is, since the document contents of the encapsulated document file 300 and the feature amount information thereof have a one-to-one relationship, there is a difference in the feature amount information between the pre-edited and the edited encapsulated document file.

  In the present embodiment, when the feature amount information is different, a dialog box 51 as shown in FIG. 17 is displayed, and a selection button 51a for determining whether or not to execute the process for changing the document ID information of the encapsulated document file. , 51b (step S84; change confirmation process). Here, when the user selects the document ID information changing process (Yes in step S85, “Yes” in FIG. 17), the document ID changing program in the encapsulated document file saves the document ID information. The changed document ID information is changed (step S86), and the inter-document communication process is terminated (step S87).

  As the document ID information changing process, for example, one lower digit value of the document ID number is added. That is, the document ID information before the change is No. If it is 56342-00, the document ID information after the change is No. 56342-01. No. in the network. When the document ID information of 56342-01 is used, one is added in order.

  Because the document ID information is different, the encapsulated document file 300 of the computer 10A and the computer 10D is distinguished as different electronic documents. Therefore, when the next communication process is performed, it is possible to determine whether or not the communication process of the encapsulated document file is necessary or the content only by comparing the document ID information 331 without calculating the feature amount information.

  If the user does not select the change processing of the document ID information 331, the selection buttons 53a and 53b can be used to select whether or not to update the document content information of the encapsulated document file as shown in FIG. A dialog box 53 that can be displayed is displayed. When the user does not select the update processing of the encapsulated document file by this button selection operation, the communication processing between the documents is terminated (step S87).

  When the update processing of the encapsulated document file is selected (Yes in step S88), the encapsulated document file is transmitted from the computer 10A to the computer 10D (step S89). The computer 10D receives the encapsulated document file 300 from the computer 10A (step S90), and updates the document content information of the encapsulated document file held by the computer 10D using the content information update program (step S91).

  As an update processing method, the encapsulated document file of the computer 10D is erased and the encapsulated document file of the computer 10A is stored, or the content file 310 in the encapsulated document file 300 of the computer 10A is taken out and the computer For example, a process for replacing the content file 310 in the 10D encapsulated document file 300 may be used. After matching the document content information of the encapsulated documents of the computer 10A and the computer 10D by the update process, a communication process between the documents is executed (steps S92 and S93).

  Although an example in which the document content information of the encapsulated document file of the computer 10D is updated with reference to the document content information of the encapsulated document file 300 of the computer 10A is shown here, conversely, the encapsulated document file of the computer 10D is shown. The document content information of the encapsulated document file 300 of the computer 10A may be updated with reference to the document content information 300.

  By executing the above processing, even in an environment where the use of a server or the like that centrally manages document ID information in the network 30 is restricted, it is efficient without creating a large amount of unnecessary document ID information 331. By changing the document ID information, it is possible to distinguish the document content information updated by the editing process, determine the communication partner, and provide an encapsulated document file for executing the communication process.

(Embodiment 4)
FIG. 19 is a diagram showing an example of an encapsulated document file structure according to the fourth embodiment of the present invention, and this embodiment relates to the invention of claim 2 .

  As shown in the figure, the encapsulated document file in this embodiment is composed of a content file 410, an operation program file 420, and a document specifying file 430.

  In the content file 410, content information indicating the document content of the encapsulated document file 400, such as text information 411, image information 412, and audio information 413, is stored as in the above-described embodiments.

  The operation program file 420 is similar to the program included in the third embodiment described above (the number at the end indicates the correspondence), and includes a feature amount comparison program 422, a communication determination program 423, and a communication program 424. And a document ID changing program 425 is stored.

  The feature amount comparison program 422 has a function of comparing whether or not the feature amount information of the own document and the feature amount information of the encapsulated document file owned by the computer in the network 30 are the same by the electronic document processing apparatus 10. It is realized. The communication determination program 423 is a computer having an encapsulated document file having the same feature quantity information for a plurality of computers in the network 30 based on the execution result of the feature quantity comparison program 422 by the electronic document processing apparatus 10. A function to determine whether or not is realized. At that time, the encapsulated document file to be subjected to the communication process is specified by referring to at least one of the document ID information and the feature amount information stored in the document specifying file 430.

  The communication program 424 has a function of executing communication processing with a computer in which the feature amount information is determined to be the same by the communication determination program 423 in cooperation with the electronic document processing apparatus 10. In the operation program file 420, various operation programs such as a display program for displaying the content information 411 stored in the content file 410 and a content information update program for updating the document contents are stored as necessary. can do.

  The document identification file 430 stores document ID information 431 for identifying the encapsulated document file and feature amount information 432 of the encapsulated document file 400. The document ID change program 425 includes a feature amount comparison program. The document ID information 431 stored in the document identification file 430 is changed according to the comparison result of the feature amount information 423.

  In the example illustrated in FIG. 19, the document ID information 431 includes, for example, “No. 56342-00 '. The number of the document ID information is information assigned when the encapsulated document file 400 is created, and the communication program 424 refers to this number to identify the encapsulated document file 400 that executes communication processing. The feature amount information 432 is, for example, “gdtuihd 329f9f”. This information is information indicating the feature quantity of the encapsulated document file 400, and is calculated when the encapsulated document file 400 is edited and the document content information is updated.

  FIG. 20 is a flowchart relating to a feature amount information calculation process executed when the document content information is updated.

  In the figure, first, the user creates an encapsulated document file 400 (step S101), performs document editing work on the encapsulated document file 400 (step S102), and updates the document content information of the encapsulated document file 400. (Step S103). Then, when updating the document content information, the feature amount information 432 of the encapsulated document file 400 is calculated (step S104). The feature amount information 432 is calculated in the same manner as the feature amount calculation in the second embodiment, and the calculated feature amount information 432 is stored in the document specifying file 430 in the encapsulated document file 400 (step S105). . Thereby, when the encapsulated document file 400 is edited, the feature amount information 432 of the encapsulated document file 400 is automatically updated and stored in the document specifying file 430.

  FIG. 21 is a flowchart regarding the communication method of the encapsulated document file. In the figure, the same steps as those shown in FIG. 15 or FIG. 16 are given the same step numbers (any one of S71 to S93), and different processing contents will be described in detail.

  In this process, first, after the computer 10A transmits the document ID information, the communication determination program 423 in each computer capable of responding operates, and the process of searching for documents having the same ID information is executed. Are searched for another computer having the encapsulated document file 400 having the same document ID information as the document (own document) in the computer 10A (steps S71 to S74).

  If there is no computer having the encapsulated document file 400 having the same document ID information in the network 30 (No in step S74), the communication processing between documents is terminated (step S75). If there is a computer having an encapsulated document file having the same document ID information (Yes in step S74), the feature amount information 432 stored in the document specifying file 430 is transferred from the computer 10D to the computer 10A. It transmits to the encapsulated document file (step S106). The encapsulated document file 400 of the computer 10A receives the transmitted feature amount information 432 (step S78).

  Next, the computer 10A uses the feature amount comparison program 422, the feature amount information transmitted from the encapsulated document file of the computer 10D, and the features of the document specifying file 430 in the encapsulated document file 400 of the computer 10A. It is determined whether or not the quantity information 432 has the same value. If the feature amount information is the same (Yes in step S81), the document contents of the encapsulated document file 400 in the computer 10A and the computer 10D are the same, and communication processing between documents is performed (step S82). To S83).

  The processing after comparing and determining the feature amount information is performed in substantially the same manner as in the third embodiment. However, if the feature amount information is not the same (Yes in step S81), the processing between steps S91 and S92 described above is performed. A process of step S109 for calculating and storing the feature amount of the updated encapsulated document file is added.

  In this post-processing, when the document information content of the encapsulated document file 400 is updated, the feature amount information 432 of the encapsulated document file 400 after the update processing is calculated and the feature amount information 432 of the document specifying file 430 is stored. .

  By executing the series of communication processes as described above, the communication partner can be determined without calculating the feature amount information 432 of the encapsulated document file 400 during the communication determination process. It is possible to provide an encapsulated document structure that can perform an initial operation at the time of communication processing at high speed.

(Embodiment 5)
FIG. 23 is a diagram showing an example of an encapsulated document file structure according to the fifth embodiment of the present invention. This embodiment relates to the inventions of claims 5 and 6 .

  In the present embodiment, an encapsulated document structure that can be updated for each content object, instead of processing the entire document when updating the document, by calculating feature amount information for each content object that constitutes the content file. provide.

  The encapsulated document file 500 of this embodiment illustrated in FIG. 23 is almost the same as that of the third and fourth embodiments, and the content file 510 serving as the document content information of the encapsulated document file 500 is a plurality of content information objects. (Hereinafter referred to as a content object) 511 to 514 and the like. Here, the content objects 511 and 512 are text information, and the content objects 513 and 514 indicate image information or audio information pasted on a document. As an object division unit, each text information paragraph may be divided as one object, or each document page may be divided as one object. Regarding image information, each image may be divided as one object, or one image may be arbitrarily divided from image information and divided into a plurality of objects.

  In the third and fourth embodiments, only the feature amount information of the encapsulated document file is calculated. In this embodiment, the feature amount information of the content objects 511 to 514 constituting the content file 510 in the encapsulated document file 500 is calculated. Is also calculated. Document ID information 531 and feature amount information 532 are stored in the document specifying file 530 in the encapsulated document file 500.

  As shown in FIG. 24A, the document identification file 530 has a document ID number as the document ID information 531, feature amount information 532 of the encapsulated document file 500, and feature amount information and operation of the content file 510. The feature amount information of the program file 520 is included. Further, as the feature amount information of the content file 510, information (for example, “ngieuhiuhsiti” in FIG. 24A) representing the feature amount of the entire content file 510 and its calculation are used. The feature amount information of the specific or each content file (for example, “poihiaegthy” and “qhsriuibuig” in FIG. 24A) is used as the feature amount information of the operation program file 520. Information to be used (for example, “jtijdioahighiua” in FIG. 24A) and used for calculation thereof Contains feature amount information of a particular or each operation program (for example, FIG. 24 in (a) 'eijihauhutr', 'iuiaiuheuht'). The feature amount information 532 has a tree structure as further illustrated in FIG. The feature amount information of the entire content file 510 may be calculated from, for example, information obtained by combining the content objects 511 and 512, or may be calculated from information obtained by combining the feature amount information of the content objects 511 and 512.

  FIG. 25 and FIG. 26 are flowcharts showing the communication processing procedure of the encapsulated document file 500 in this embodiment.

  In the communication process shown in the figure, as in the case of the third and fourth embodiments, first, after the computer 10A transmits the document ID information, the communication determination program 523 in each computer that can respond is activated, and the same ID A document search process having information is executed, and another computer having the encapsulated document file 500 having the same document ID information as that of the document (own document) in the computer 10A is searched from the network 30 (step S111). To S114). In the figure, the computer 10D is a computer that holds an encapsulated document file 500 having the same document ID information.

  Next, as the encapsulated document file of the computer 10D, the document specifying file in the own document is transmitted from the computer 10D to the encapsulated document file 500 of the computer 10A (step S116).

  The encapsulated document file 500 of the computer 10A receives the transmitted document specific file (step S117). Then, using the feature amount comparison program 520, the document specifying file transmitted from the encapsulated document file of the computer 10D is compared with the feature amount of the document specifying file 530 in the encapsulated document file 500 of the computer 10A. (Step S118).

  FIG. 27 is a flowchart showing an example of the feature amount comparison process.

  In the figure, first, it is compared whether the feature amount information 532 of the encapsulated document file 500 matches between the computer 10A and the computer 10D (step S142). If the feature amount information 532 matches (Yes in step S143), the document content of the encapsulated document file 500 is the same, so the communication process is started.

  If the feature amount information does not match (No in step S143), a feature file feature amount comparison process (steps S145 and S146) and an operation program file feature amount comparison process (steps S149 and S150) are performed. . If the feature amount information of the content file does not match (No in step S146), the feature amounts of the content objects constituting the content file are further compared (step S147) to search for content information with different feature amount information. (Step S151), the object name of the content information is stored in the document identification file (step S148).

  The operation program file is also subjected to a comparison process substantially similar to the feature amount comparison process.

  Through the above processing, it is possible to specify object names of content information having different document contents in the encapsulated document file 500 of the computer 10A and the computer 10D. The processing after comparing and determining the feature amount information is performed in the same manner as in the third embodiment.

  When the document content information of the encapsulated document file 500 is updated in later processing, information such as the document specifying file 530 and the content objects 511 to 514 is transmitted. On the receiving side, referring to the object name information of the content information stored in the document specific file, the files such as the content objects 511 to 514 of the own document are updated.

  By executing the above processing, it is possible to provide an encapsulated document structure that can be processed for each of the content objects 511 to 514, instead of processing the entire document at the time of updating the document by editing work. That is, since only different content objects can be updated, it is possible to provide an encapsulated document structure that can reduce the amount of data to be updated and can be processed for each content object.

  As described above, the electronic document processing apparatus and the encapsulated document structure of the present invention automatically communicate between computers having the same electronic document among a plurality of computers having different environments such as application installation states. It can be applied to and useful for communication tools, electronic commerce, conference systems, document workflow systems such as examination approval, minutes, and document management systems.
