DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] An information processing system according to this embodiment will be described with reference to Fig. 1. Fig. 1 shows an example of the configuration of the information processing system according to this embodiment.

[0020] The information processing system according to the present embodiment includes, as an example, a terminal device 10, a dedicated server 12, a mail server 14, and a terminal device 16. The number of each device is merely an example, and a plurality of terminal devices, a plurality of mail servers, etc. may be included in the information processing system.

[0021] In this embodiment, the terminal device 10 is the device that sends the e-mail (i.e., the device used by the user who sends the e-mail), and the terminal device 16 is the device that sends the e-mail (i.e., the device used by the user who is the destination of the e-mail). Of course, the terminal device 10 may receive the e-mail, and the terminal device 16 may send the e-mail.

[0022] The terminal devices 10 and 16 are, for example, personal computers (hereinafter, referred to as "PCs"), tablet PCs, smartphones, or mobile phones.

[0023] The sender terminal device 10 is equipped with a plug-in 18. The plug-in 18 is, for example, a program, and is executed by a processor to realize the function of the plug-in 18. The plug-in 18 has a function of changing the destination of an e-mail from the mail server 14 to the dedicated server 12, and sending the e-mail to the dedicated server 12.

[0024] The dedicated server 12 is an example of an information processing device, and includes a document generation unit 20, an access information management unit 22, and a display control unit .

[0025] The document generation unit 20 receives an e-mail sent from the terminal device 10, and generates a document including the contents of the body of the e-mail.

[0026] An e-mail includes, for example, a header section, which is a standardized section, and a body text. The header section includes, for example, information indicating the destination of the e-mail (for example, the name and e-mail address of the destination), information indicating the sender (for example, the name and e-mail address of the sender), information indicating the subject, and information regarding the structure of the e-mail. In the body text, a character string such as a message is written by the sender user.

[0027] The document generated by the document generation unit 20 may include all or part of the information contained in the header portion in addition to the contents of the body of the e-mail.

[0028] The document according to the present embodiment is, for example, a web page in HTML format, a text file, a rich text file, or a PDF file. The document includes, for example, character strings, images (for example, bitmap images or vector images), and graphics. The document may contain only character strings, may contain character strings and images, or may contain only images.

[0029] The access information management unit 22 generates access information regarding the document generated by the document generation unit 20, and manages the history of users who have accessed the document and operations on the document. The access information includes, for example, address information for accessing the document, the email address of the email destination, authentication information required when accessing the document (for example, an access ID and an access password), and history information showing the history of operations on the document. The address information is information indicating the location of the document (for example, information indicating the address of a storage area where the document data is stored). For example, if the document is a web page, the address information is the URL of the web page.

[0030] In addition, the access information management unit 22 sends an email containing the above address information but not all of the content of the body of the email to the email address specified as the destination of the email via the mail server 14.

[0031] Not including all of the content of the body of an email means not including the content of the body itself, and may mean, for example, not including all of the content of the body (i.e., not including even a portion of the content of the body, or not including the content of the body at all), or not including some of the content of the body (i.e., including some of the content of the body).

[0032] When the address indicated by the address information is accessed by the user who is the destination of the e-mail, the display control unit 24 displays the document on the display of the terminal device 16 used by the destination user. For example, when the document is a Web page and the address information is the URL of the Web page, and the destination user operates the terminal device 16 to access the URL, the display control unit 24 displays the Web page on the display of the terminal device 16. In this case, the display control unit 24 may be a Web server.

[0033] The mail server 14 receives e-mails and transmits the e-mails to their destinations. The mail server 14 is, for example, a known mail server.

[0034] Hereinafter, the hardware configuration of the terminal device 10 will be described with reference to Fig. 2. Fig. 2 shows an example of the hardware configuration of the terminal device 10. Note that the terminal device 16 also has the same hardware configuration as the terminal device 10.

[0035] The terminal device 10 includes, for example, a communication device 26, a UI 28, a memory 30, and a processor 32.

[0036] The communication device 26 is a communication interface having a communication chip, a communication circuit, etc., and has a function of transmitting information to other devices and a function of receiving information from other devices. The communication device 26 may have a wireless communication function or a wired communication function.

[0037] The UI 28 is a user interface and includes at least one of a display and an operation device. The display is a display device such as a liquid crystal display or an EL display. The operation device is a keyboard, input keys, an operation panel, or the like. The UI 28 may be a UI such as a touch panel that combines a display and an operation device.

[0038] The memory 30 is a device constituting one or more storage areas for storing various types of information. The memory 30 is, for example, a hard disk drive, various types of memory (e.g., RAM, DRAM, ROM, etc.), other storage devices (e.g., optical disks, etc.), or a combination thereof. One or more memories 30 are included in the terminal device 10. For example, the memory 30 of the source terminal device 10 stores a plug-in 18 (i.e., a program that realizes the functions of the plug-in 18).

[0039] The processor 32 is configured to control the operation of each unit of the terminal device 10. The processor 32 may have a memory. For example, the processor 32 executes the plug-in 18 to realize the function of the plug-in 18. The processor 32 corresponds to an example of a first processor.

[0040] The hardware configuration of the dedicated server 12 will be described below with reference to Fig. 3. Fig. 3 shows an example of the hardware configuration of the dedicated server 12.

[0041] The dedicated server 12 includes, for example, a communication device 34 , a UI 36 , a memory 38 , and a processor 40 .

[0042] The communication device 34 is a communication interface having a communication chip, a communication circuit, etc., and has a function of transmitting information to other devices and a function of receiving information from other devices. The communication device 34 may have a wireless communication function or a wired communication function.

[0043] The UI 36 is a user interface and includes at least one of a display and an operation device. The display is a display device such as a liquid crystal display or an EL display. The operation device is a keyboard, input keys, an operation panel, or the like. The UI 36 may be a UI such as a touch panel that combines a display and an operation device.

[0044] The memory 38 is a device constituting one or more storage areas for storing various types of information. The memory 38 is, for example, a hard disk drive, various types of memory (e.g., RAM, DRAM, ROM, etc.), other storage devices (e.g., optical disks, etc.), or a combination thereof. One or more memories 38 are included in the dedicated server 12.

[0045] The processor 40 is configured to control the operation of each part of the dedicated server 12. The processor 40 may have a memory. For example, the processor 40 executes a program to realize the functions of the document generation part 20, the access information management part 22, and the display control part 24. The program is stored in, for example, the memory 38. The processor 40 corresponds to an example of a second processor.

[0046] The flow of processing by the information processing system according to this embodiment will be described below with reference to Fig. 4. Fig. 4 is a sequence diagram showing the flow of processing.

[0047] First, the user who is the sender of the e-mail operates the terminal device 10 to enter the contents in the body of the e-mail, specify the destination e-mail address, and instruct the sending of the e-mail. This operation is the same as sending a normal e-mail. In addition, a file such as a document may be attached to the e-mail. Hereinafter, the e-mail sent in this manner will be referred to as the "first e-mail."

[0048] When the sender user instructs transmission of the first electronic mail, the plug-in 18 of the terminal device 10 transmits the first electronic mail to the dedicated server 12 (S01). In other words, the first electronic mail is transmitted to the dedicated server 12 without being transmitted to the normal mail server 14.

[0049] Next, the document generation unit 20 of the dedicated server 12 receives the first e-mail sent from the terminal device 10 and generates a document including the content of the body of the first e-mail (S02). For example, the document generation unit 20 generates a Web page including the content of the body of the first e-mail.

[0050] Next, the access information management unit 22 generates access information for the document generated by the document generation unit 20 (S03). The access information includes the address of the document generated by the document generation unit 20 (e.g., the URL of a web page), the email address of the destination of the first email, an access ID, an access password, and operation history information.

[0051] Next, the access information management unit 22 sends an email (hereinafter referred to as the "second email") that includes the address information of the document (e.g., the URL of a web page) but does not include all of the content of the body of the first email, to the email address of the destination of the first email via the mail server 14 (S04).

[0052] The processor of the destination terminal device 16 receives the second electronic mail from the mail server 14 (S05).

[0053] The second e-mail contains address information of the document (e.g., the URL of a web page), and when the destination user operates terminal device 16 to access the address indicated by the address information (e.g., the URL of a web page) (S06), display control unit 24 causes the document at that address (e.g., the web page specified by the URL) to be displayed on the display of terminal device 16. The destination user can view the displayed document or perform other operations on the document. On the other hand, since the second e-mail does not include the entire content of the body of the first e-mail, display control unit 24 will not cause the entire content of the body of the first e-mail to be displayed on the display unless the destination user accesses the address indicated by the address information.

[0054] When the destination user accesses the document, the access information management unit 22 adds information indicating that the destination user has accessed the document to the operation history information included in the access information of the document, and updates the history information (S07). For example, the access information management unit 22 adds information indicating which destination user accessed the document and when to the history information of the document. The access information management unit 22 may also add information indicating the operation performed on the document by the destination user who accessed the document to the history information of the document.

[0055] The process for correcting a document will be described below with reference to Fig. 5. Fig. 5 is a sequence diagram showing the flow of the process.

[0056] First, the user who is the sender of the first e-mail corrects the document including the contents of the body of the first e-mail (S10). For example, it is possible to correct the contents of the body of the first e-mail if there is an error in the contents. The sender user operates the terminal device 10 to request the dedicated server 12 to correct the document, and corrects the document on a screen for correction, for example. If a file is attached to the first e-mail, the file may be replaced with another file, or a new file may be attached.

[0057] The document generation unit 20 of the dedicated server 12 modifies the document according to the modification instruction from the sender user, and generates a document reflecting the modification (hereinafter referred to as a "modified document") (S11). For example, if the document is a Web page, the Web page is modified and a modified Web page is generated.

[0058] When a document is modified and a modified document is generated, the access information of the document before modification is linked to the modified document as the access information of the modified document. Even if a document is modified, the address information does not change. Therefore, the modified document can be accessed by accessing the address (e.g. URL) indicated by the address information.

[0059] When the document is modified, the access information management unit 22 updates the operation history information included in the access information of the modified document (S12). Here, the access information management unit 22 adds information indicating that the document has been modified to the history information. If the document is a web page, the access information management unit 22 adds information indicating that the web page has been modified to the history information included in the access information of the web page, and updates the history information.

[0060] Next, the access information management unit 22 refers to the operation history information included in the access information of the revised document, and checks whether or not there is a destination user who accessed the document before the revision (for example, the Web page before the revision) (S13).

[0061] If there is a destination user who accessed the document before revision (S13, Accessed), the access information management unit 22 notifies only the destination user who accessed the document before revision that the document has been revised (S14). For example, the access information management unit 22 sends an email including information indicating that the document has been revised, via the mail server 14, to the email address of the destination user who accessed the document before revision. The access information management unit 22 does not notify the destination users who did not access the document before revision that the document has been revised.

[0062] The processor of the destination terminal device 16 receives the email containing information indicating that the document has been modified (S15).

[0063] When the destination user operates terminal device 16 to access the address (e.g., URL) of the revised document (S16), display control unit 24 causes the revised document at that address (e.g., the revised Web page specified by the URL) to be displayed on the display of terminal device 16. The address of the revised document is the address contained in the previously sent second e-mail. The destination user can view the displayed document and perform other operations on the document.

[0064] When the destination user accesses the revised document, the access information management unit 22 adds information indicating that the destination user has accessed the revised document to the operation history information contained in the access information of the revised document, and updates the history information (S17).

[0065] If no destination user accessed the document before the revision (S13, no access), the access information management unit 22 does not notify the destination user that the document has been revised. In other words, if none of the destination users of the first e-mail accessed the document before the revision, the access information management unit 22 does not notify the destination user that the document has been revised.

[0066] After the document is revised, when a destination user who has not accessed the document before revision operates terminal device 16 to access the address listed in the second e-mail, display control unit 24 causes the revised document to be displayed on the display of terminal device 16. In this way, the revised document is provided to users who have not accessed the document before revision, and not the document before revision.

[0067] The process shown in FIG. 4 will be described below with a concrete example.

[0068] First, user ZZZ, who is the sender of the first electronic mail, operates the terminal device 10 to write the contents in the body of the first electronic mail, specify the destination electronic mail address, and instruct the sending of the first electronic mail. As an example, it is assumed here that an electronic mail is to be sent to two users (e.g., user AAA and user BBB). User ZZZ specifies the respective electronic mail addresses of users AAA and BBB and instructs the sending of the first electronic mail.

[0069] 6 shows the contents of the first email 42. The email address of user AAA is specified as the destination, and the email address of user BBB is specified as CC (carbon copy), which is included in the destination concept.

[0070] The subject and the contents of the message are also described in the first email 42. The subject is "Product Conference" and the contents of the message inform the destination user of the date, time and venue of the conference. Also, a file of a map to the venue is attached to the first email 42.

[0071] When user ZZZ instructs transmission of the first email 42, the plug-in 18 of the terminal device 10 transmits the first email 42 to the dedicated server 12. In other words, the first email 42 is transmitted to the dedicated server 12 without being transmitted via the mail server 14 to users AAA and BBB.

[0072] When the document generation unit 20 of the dedicated server 12 receives the first email 42 from the terminal device 10, the document generation unit 20 generates a document including the content of the body of the first email 42. As an example, the document generation unit 20 generates a Web page including the content of the body of the first email 42.

[0073] FIG. 7 shows a Web page 44 generated by the document generating unit 20. This Web page 44 is an example of a document including the contents of the text of the first email 42. In the example shown in FIG. 7, in addition to the contents of the text, the destination, CC, and subject are also written on the Web page 44. Also, a file 46 of a map attached to the first email 42 is placed on the Web page 44 in a downloadable state. For example, a hyperlink to the file 46 is written on the Web page 44, and the file 46 is downloaded by accessing the hyperlink. The data of the Web page 44 is stored on the dedicated server 12 or another device.

[0074] Next, the access information management unit 22 generates access information for the Web page 44. The access information includes the URL of the Web page 44, an email address of the destination of the first email (e.g., the email addresses of users AAA and BBB), an access ID, an access password, and operation history information. The URL, access ID, and access password for the Web page 44 are generated by the access information management unit 22. The access information for the Web page 44 is stored in the dedicated server 12.

[0075] The access ID is an ID corresponding to a combination of the URL of the web page 44 and the destination email address. For example, an access ID is generated for each destination email address (i.e., for each destination user). Specifically, an access ID for user AAA and an access ID for user BBB are generated.

[0076] The access password is a password that corresponds to the access ID. When an access ID is generated for each destination email address, a corresponding access password is generated for each destination email address.

[0077] The combination of the access ID and the access password is required when accessing the Web page 44. When a combination of the access ID and the access password that matches the combination of the access ID and the access password included in the access information of the Web page 44 is entered, access to the Web page 44 is permitted, and the Web page 44 is displayed.

[0078] It should be noted that an access ID and an access password do not have to be generated for each destination email address, but may be generated so that the access ID and the access password are common to all destination users.

[0079] The operation history information includes information indicating the history of operations performed by the user thereafter. For example, the history information includes information indicating that the source user ZZZ has modified the web page 44, information indicating that the destination user has accessed the web page 44, information indicating that the destination user has viewed the web page 44, and information indicating that the destination user has downloaded the file 46.

[0080] The access information management unit 22 sends a second e-mail, which includes the URL of the web page 44 but does not include the entire content of the body of the first e-mail 42, to the e-mail address of the destination of the first e-mail 42 via the mail server 14. In this case, the second e-mail is sent to the e-mail addresses of users AAA and BBB.

[0081] Figure 8 shows the contents of a second email 48 sent to the email address of user AAA. Figure 9 shows the contents of a second email 50 sent to the email address of user BBB.

[0082] 8 and 9, the same URL is described in the second emails 48 and 50. This URL is the URL of the web page 44.

[0083] The second email 48 addressed to user AAA contains an access ID for user AAA, and the second email 50 addressed to user BBB contains an access ID for user BBB. The access ID for user AAA and the access ID for user BBB are different access IDs.

[0084] In the examples shown in Figs. 8 and 9, the access passwords are sent to users AAA and BBB by separate e-mails. The access password for user AAA is a password corresponding to the access ID for user AAA. The access password for user BBB is a password corresponding to the access ID for user BBB.

[0085] 8 and 9, the content of the body of the first email 42 is not included at all in the second email 48, 50. In other words, not even a part of the content of the body of the first email 42 is included in the second email 48, 50. As another example, a part of the content of the body of the first email 42, the subject, or the destination may be included in the second email 48, 50.

[0086] The access information of the web page 44 includes information about the user AAA and information about the user BBB.

[0087] When the second email 48 is sent to the email address of the user AAA, the information about the user AAA includes the following: URL of web page 44: http: / / aaa.bbb.co.jp / f9deiowail5m32f Email Address: The email address of user AAA · Access ID for user AAA: 3f84mt8gh3 - Access password for user AAA: A string corresponding to the access ID "3f84mt8gh3" Operation history: None At this point, user AAA has not accessed web page 44, viewed web page 44, or downloaded file 46, so the operation history is "none."

[0088] When the second email 50 is sent to the email address of user BBB, the information about user BBB includes the following: URL of web page 44: http: / / aaa.bbb.co.jp / f9deiowail5m32f Email Address: User BBB's email address · Access ID for user BBB: f3489hrga - Access password for user AAA: A string corresponding to the access ID "f3489hrga" Operation history: None At this point, user BBB has not accessed Web page 44, viewed Web page 44, or downloaded file 46, so the operation history is "none."

[0089] The terminal device 16 of the user AAA receives the second email 48 from the mail server 14. Similarly, the terminal device 16 of the user BBB receives the second email 50 from the mail server 14.

[0090] In the following, it is assumed that user AAA accesses web page 44 and user BBB does not access web page 44 .

[0091] The user AAA operates the terminal device 16 to access the URL of the web page 44 described in the second email 48 .

[0092] When the URL of the Web page 44 is accessed, a screen 52 shown in Fig. 10 is displayed on the display of the terminal device 16 of the user AAA. The screen 52 is a screen for inputting an access ID and an access password.

[0093] When the user AAA inputs an access ID and an access password for the user AAA on the screen 52 and presses the OK button, the combination of the access ID and the access password input here is sent to the dedicated server 12. The access information management unit 22 permits the user AAA to access a Web page having access information including the combination of the input access ID and the access password. For example, the access information management unit 22 checks whether or not the combination of the input access ID and the access password is included in the access information of the Web page 44. If the combination of the input access ID and the access password is included in the access information of the Web page 44, the access information management unit 22 permits the user AAA to access the Web page 44, and if the combination of the input access ID and the access password is not included in the access information of the Web page 44, the access information management unit 22 does not permit the user AAA to access the Web page 44.

[0094] When user AAA is permitted to access the Web page 44, the display control unit 24 causes the Web page 44 to be displayed on the display of the terminal device 16 of user AAA. The Web page 44 shown in Fig. 7 is displayed on the display. This allows user AAA to view the Web page 44.

[0095] In addition, user AAA can download file 46 by accessing a hyperlink provided on web page 44 .

[0096] As an example, it is assumed here that a web page 44 is displayed on the display of the terminal device 16 of the user AAA and a file 46 is downloaded.

[0097] The access information management unit 22 updates the operation history information in response to an operation by a user AAA on the Web page 44.

[0098] When the Web page 44 is displayed on the display of the terminal device 16 of the user AAA and the file 46 is downloaded by the user AAA, the information about the user AAA included in the history information of the Web page 44 is updated to the following content. URL of web page 44: http: / / aaa.bbb.co.jp / f9deiowail5m32f Email Address: The email address of user AAA · Access ID for user AAA: 3f84mt8gh3 - Access password for user AAA: A string corresponding to the access ID "3f84mt8gh3" · Operation history: browsing, downloads Because Web page 44 is displayed on the display of terminal device 16 of user AAA, the fact that Web page 44 has been viewed is recorded as part of the operation history of user AAA. Also, because file 46 has been downloaded by user AAA, the fact that the file has been downloaded is recorded as part of the operation history of user AAA. Also, access information management unit 22 records the date and time when user AAA accessed Web page 44 (i.e., the date and time when user AAA started viewing Web page 44) and the date and time when user AAA downloaded file 46 as part of the operation history of user AAA. Information indicating these dates and times is included in the history information of Web page 44.

[0099] Since user BBB has not accessed web page 44, the information about user BBB contained in the history information of web page 44 is not updated.

[0100] The process shown in FIG. 5 will be described below with a concrete example.

[0101] First, user ZZZ, who is the sender of the first electronic mail, requests the dedicated server 12 to modify the web page 44 by operating the terminal device 10. When multiple first electronic mails are sent by user ZZZ and multiple web pages are generated, if the user ZZZ wishes to modify a web page, a list of the web pages is displayed on the display of the terminal device 10, and user ZZZ selects the web page to be modified from the list and requests the modification of the web page.

[0102] When the user ZZZ requests to modify the Web page 44, a screen for modifying the Web page 44 is displayed on the display of the terminal device 10. An example of the screen 54 is shown in FIG.

[0103] Screen 54 displays a list 56 of the history of operations on web page 44, buttons 58 for instructing corrections and notification of the corrections, and buttons 60 for instructing changes to the web page 44, file 46, and attached files to be corrected.

[0104] 6 to 10, user AAA viewed web page 44 and downloaded file 46, and user BBB did not access web page 44. List 56 of the operation history includes the date and time when user AAA viewed web page 44 and the date and time when user AAA downloaded file 46.

[0105] On the screen 54, the user ZZZ can modify the web page 44, change the file 46 to another file, or delete the file 46.

[0106] In this example, the "date and time" written on the web page 44 is modified, and the file 46 is changed to another file.

[0107] FIG. 12 shows the contents after the correction. Web page 62 is a Web page that reflects the correction of the "date and time." Specifically, the "date and time" written on Web page 44 has been corrected from "14:00-15:00" to "14:30-15:30." In addition, file 46 attached to Web page 44 has been changed to another file 64. Web page 62 is an example of a corrected document.

[0108] The document generating unit 20 generates a web page 62 by modifying the web page 44 according to the modification operation by the user ZZZ, and changes the file 46 to a file 64. The data of the web page 62 is stored in the dedicated server 12 or another device.

[0109] When web page 44 is revised to web page 62, the access information of web page 44 is linked to web page 62 as is. The URL for accessing it is not changed, and the URL of web page 44 is used as the URL of web page 62. History information of operations on web page 44 is also included in the access information of web page 62.

[0110] When user ZZZ presses button 58, access information management unit 22 notifies only destination users who accessed Web page 44 before the modification that Web page 44 has been modified.

[0111] Since user AAA has accessed and viewed web page 44 and downloaded file 46, but user BBB has not accessed web page 44, access information management unit 22 sends an email including information indicating that web page 44 has been modified and file 46 has been changed to the email address of user AAA via mail server 14. Access information management unit 22 does not send the email to user BBB.

[0112] When the processor of the terminal device 16 of the user AAA receives the email containing information indicating that the web page 44 has been modified and the file 46 has been changed, the processor displays the contents of the email on the display of the terminal device 16. The contents of the email are shown in FIG.

[0113] The e-mail describes the modified parts of the Web page 44, as indicated by the reference numeral 66. In this case, since the "date and time" has been modified, the details of the modification are described. Also, since the file 46 before the modification has been downloaded, as indicated by the reference numeral 68, a message urging the user to re-acquire the modified file 64 is described. The details indicated by the reference numerals 66 and 68 are displayed on the display of the terminal device 16. Note that if the Web page 44 has been viewed but the file 46 has not been downloaded, the details indicated by the reference numeral 68 are not described.

[0114] The corrected Web page 62 is displayed on the display of the terminal device 16 of the user AAA. Note that the Web page 62 may be displayed when the user AAA accesses the URL of the Web page 62 (i.e., the URL of the Web page 44 before the correction).

[0115] After the Web page 44 has been modified, when the user BBB operates the terminal device 16 to access the URL listed in the second e-mail, a screen 52 shown in FIG. 10 is displayed on the display of the terminal device 16 of the user BBB. When the user BBB inputs an access ID and an access password for the user BBB on the screen 52 and presses the OK button, the combination of the access ID and the access password input here is transmitted to the dedicated server 12. If the combination of the input access ID and the access password is included in the access information of the Web page 62, the access information management unit 22 permits the user BBB to access the Web page 62, and if the combination of the input access ID and the access password is not included in the access information of the Web page 62, the access information management unit 22 does not permit the user BBB to access the Web page 62.

[0116] When user BBB is permitted to access Web page 62, the display control unit 24 displays Web page 62 on the display of the terminal device 16 of user BBB, as shown in Fig. 14. Web page 62 is a Web page that reflects the modifications made to Web page 44. This allows user BBB to view the modified Web page 62. For example, user BBB can view the modified Web page 62 without recognizing that the unmodified Web page 44 has been modified.

[0117] Also, the file has been changed from file 46 to file 64. This allows user BBB to download the changed file 64. For example, user BBB can download the changed file 64 without recognizing that the file has been changed from file 46 to file 64.

[0118] The functions of each of the above terminal devices 10, 16, dedicated server 12, and mail server 14 are realized, for example, by cooperation between hardware and software. For example, the processor of each device reads and executes a program stored in the memory of each device, thereby realizing the function of each device. The program is stored in the memory via a recording medium such as a CD or DVD, or via a communication path such as a network.

[0119] In each of the above embodiments, the term "processor" refers to a processor in a broad sense, and includes general-purpose processors (e.g., CPU: Central Processing Unit, etc.) and dedicated processors (e.g., GPU: Graphics Processing Unit, ASIC: Application Specific Integrated Circuit, FPGA: Field Programmable Gate Array, programmable logic device, etc.). Furthermore, the operation of the processor in each of the above embodiments may not only be performed by one processor, but may also be performed by multiple processors located at physically separate locations working together. Furthermore, the order of each operation of the processor is not limited to the order described in each of the above embodiments, and may be changed as appropriate. [Explanation of symbols]
