Things that can be exchanged, including similar ones. Hereinafter, it is also referred to as content.
The specific person is, for example, a person (an operator of the publication destination PC 190) who is a destination such as a mail address designated by a person who publishes a document to be described later (an operator of the document publication setting PC 170 (an in-house user)). In general, it is a person who cannot access the target document, for example, when the document is an in-house document, this is a person outside the company.
Also, “to open” means to make a target document in a state where it can be browsed, and includes, for example, making it possible to download (transmit).

Between the document publication setting PC 170 and the publication information receiving module 105 of the document management server 100, publication setting information input (destination mail address, target document designation) 103 is performed via the in-house communication line 198. The public information receiving module 105 receives a document public request from an in-house user (user of the document public setting PC 170), displays the public information input screen by transmitting it to the document public setting PC 170, and performs user operations (keyboard, Based on an operation on a mouse, a touch panel, and so on (hereinafter the same applies), the user specifies a public setting information such as a destination e-mail address, a document to be disclosed, and a publication period. This will be described later with reference to FIG.
Public setting information acquisition 107 is performed between the public information reception module 105 and the public information control module 110. That is, the public setting information received from the document public setting PC 170 is passed to the public information control module 110.

URL access and password setting 194 are performed via the communication line 199 between the disclosure destination PC 190 and the password setting reception module 135 of the document management server 100.

The public information control module 110 performs the following processing in cooperation with a connected module or the like. An association process associating an empty password, a document to be published, a publication period of the document with the first access position, and when the first access position is accessed, the access time is the first access position. A first determination process for determining whether or not it is within a public period associated with an access position; and if the first determination process determines that it is within a public period, the first access position A second determination process for determining whether or not the password associated with the password is empty; and if the password is determined to be empty by the second determination process, the first access position is accessed. A setting process for setting a password by the operator's operation, a generation process for generating a second access position when the password is set by the setting process, and the second determination. If the process determines that the password is not empty, the acceptance process for accepting the password by the operation of the operator who has accessed the first access position, and the password accepted by the acceptance process are the first access position If it is determined by the third determination process that the password is matched with the password associated with the password, and the third determination process determines that the password matches, the document to be published is sent to the operator. The publishing process is performed to make it publicly available. In the association process, when a second access position is generated by the generation process, the second access position is set as the first access position, and the setting process is performed at the first access position. The password set by, the document to be published, and the publication period are associated.
An empty password means a state in which no password is set, but the state may be represented by a flag indicating that no password has been set yet. In this embodiment, a flag indicating that no password is set may be used instead of an empty password.
The access position is the position (address) of information such as a web page, and includes, for example, a URL (Uniform Resource Locator), a URI (Uniform Resource Identifier), and the like. explain.

The public information control module 110 may be configured as follows. The association process further associates an expiration date of the first access position with the first access position, and when the second determination process determines that the password is not empty, the first access position Further, a fourth determination process for determining whether or not the expiration date associated with the position is within the expiration date, and when the setting process is determined not to be within the expiration date by the fourth determination process, A password is set by the operation of the operator who has accessed the first access position, and if the reception process is determined to be within the expiration date by the fourth determination process, the password is set to the first access position. You may make it receive the password by operation of the operator who accessed.
If the first access position is not accessed within the validity period, the first access position is authorized without performing a process of associating an empty password, a document to be published, and a publication period of the document. The access position (second access position) can be treated as a temporary access position (first first access position). Generally, when the first access position is not accessed within the expiration date, the operator needs to perform the operation again from the beginning. That is, in order to perform “a process of associating an empty password, a document to be published, and a publication period of the document with the first access position”, an operation by the operator is necessary, but the operation is not necessary. is there.

The public information control module 110 may use the mail notification module 125 as follows. Notification processing for notifying the operator's destination of the first access position or the second access position may be further performed.
The notification may be anything that can convey the text data of the access location such as URL, for example, e-mail, chat, message of social networking service, etc. In the following, e-mail is mainly exemplified explain.

The process performed by the public information control module 110 will be specifically described. First, the process is based on the flowchart illustrated in FIG. 3 described later.
The public information control module 110 generates public information based on the public setting information sent from the public information reception module 105. The public information is generated separately for each publication destination, and “public ID (information for uniquely identifying the public in the present embodiment)”, “password”, “identifier for identifying the target document (target document ID: book (Information for uniquely identifying a document in the embodiment) ”and“ public period ”(public information storage table 700 illustrated in FIG. 7 described later), and when it is first generated,“ public ID ”is The ID generated by the public ID issuance module 115 is held as a temporary public ID, and the “identifier identifying the target document” and “publication period” are operations of the publishing user (user of the document publishing setting PC 170). The information based on is held. “Password” is empty. After the public information is generated, the URL generation module 120 is requested to generate a URL using the temporary public ID, and the mail notification module 125 is requested to send a URL mail notification.

  When the publishing destination PC 190 accesses the URL based on the operation of the external user (the user of the publishing destination PC 190), the publishing information is specified from the publishing ID of the URL, and it is confirmed whether it is within the “publishing period” period. If it is outside the period, error information is returned to the external user (public PC 190) at that time. If it is within the period, check whether the “password” is set. If it is set, the download control module 130 is instructed to accept a password, and is downloaded after authentication. If the “password” is empty in the temporary public ID state, the public ID issuing module 115 issues a regular public ID. Further, the password setting reception module 135 is instructed to display a screen for setting a password for the PC (public PC 190) accessed from the URL, and the password input result is acquired. Copy the “identifier that identifies the target document” and “publication period” from the temporary public information, and generate and store new public information. Thereafter, the URL generation module 120 is requested to generate a URL using the official public ID, and the mail notification module 125 is requested to notify the URL of the mail.

Next, the process is based on the flowchart illustrated in FIG. 4 described later.
The public information control module 110 generates public information based on the public setting information sent from the public information reception module 105. The public information is generated separately for each publication destination, and has “public ID”, “password”, “identifier identifying the target document”, “public period”, and “public ID validity period” (illustrated in FIG. 7 described later). The public information storage table 700), when first generated, holds the ID generated by the public ID issuing module 115 as a temporary public ID, and “identifier identifying the target document”, In the “publication period”, information based on the operation of the user of the publication source (the user of the document publication setting PC 170) is held. “Password” and “Public ID expiration date” are empty. After the public information is generated, the URL generation module 120 is requested to generate a URL using a temporary ID, and the mail notification module 125 is requested to notify the URL of the mail.

  When the publishing destination PC 190 accesses the URL based on the operation of the external user (the user of the publishing destination PC 190), the publishing information is specified from the publishing ID of the URL, and it is confirmed whether it is within the “publishing period” period. If it is outside the period, error information is returned to the external user (public PC 190) at that time. If it is within the period, it is checked whether “password” is set and whether it is within the period set in “public ID expiration date”. If the “password” is set and within the expiration date, the download control module 130 is instructed to accept the password, and is downloaded after authentication. If the “password” is still empty in the temporary public ID state or the time limit set in the “public ID expiration date” has passed, the public ID issuing module 115 issues a regular public ID. Further, the password setting reception module 135 is instructed to display a screen for setting a password for the PC (public PC 190) accessed from the URL, and the password input result is acquired. Copy the “identifier that identifies the target document” and “publication period” from the temporary public information, and generate and store new public information. Thereafter, the URL generation module 120 is requested to generate a URL using the official public ID, and the mail notification module 125 is requested to notify the URL of the mail.

In response to a request from the public information control module 110, the public ID issuance module 115 issues a unique ID used for publication. For example, a random ID is issued.
In response to a request from the public information control module 110, the URL generation module 120 issues a URL including a server's FQDN (Fully Qualified Domain Name) and a public ID.
Upon receiving a request from the public information control module 110, the mail notification module 125 notifies an external user (public PC 190) by mail. The URL passed from the public information control module 110 is described in the body of the mail.
The password setting reception module 135 is instructed by the public information control module 110 that has received a URL access from an external user (public destination PC 190), and receives a password from the public information control module 110 when it is necessary to set a password. The password is displayed for an external user (public PC 190).
The download control module 130 is instructed by the public information control module 110 that has received URL access from an external user (public PC 190), and displays a password input screen on the public PC 190. Further, based on the operation of the user of the disclosure destination PC 190, the password is accepted, and after authentication by the disclosure information control module 110, the content (document) is downloaded to the disclosure destination PC 190.
In response to the request from the public information control module 110, the document information control module 140 performs document information acquisition 147 from the database 145 and content acquisition 152 from the file storage 150. Then, the obtained document information and content (document) are passed to the public information control module 110.
The database 145 stores document information and the like. The file storage 150 stores content (documents).
The SMTP server 180 is a server for sending electronic mail. For example, it corresponds to SMTP (Simple Mail Transfer Protocol) which is a mail transmission protocol (communication protocol).

Next, a processing example of the document management server 100 will be described using a flowchart.
First, it is assumed that an electronic document (attribute information and content) is stored in advance in the document management server 100 in a state that can be uniquely specified by a document ID. This is a prerequisite.
FIG. 2 is a flowchart illustrating an example of document publication processing. A flow from when the login user (user of the document publication setting PC 170) first performs the document publication operation to when the first electronic mail is sent to the publication destination will be described.
In step S <b> 202, the public information reception module 105 receives input of necessary information and requests publication of a document by an operation of a user who has logged in by the document publication setting PC 170.
Specifically, based on the operation of the logged-in user, necessary information is input and a document publication request is made.
-The following information is input based on the operation of the logged-in user.
-Documents to be published-E-mail addresses for publication destinations-Publication period

In step S204, the public information control module 110 issues a temporary public ID for each public destination, and stores the public information in association with (associating with) the public ID.
Specifically, a temporary public ID is issued for each public destination, and public information is stored in association with the temporary public ID.
・ Public information has the following information.
-Public ID: An identifier for uniquely specifying public information.
-Password ... A password for downloading document content from this public information. It is empty at this point.
-Target document ID: An identifier that identifies the target document.
-Publication period: It is a period during which the target document can be downloaded from the publication destination.
-Expiration date of public ID: Date and time when document content cannot be downloaded with public information of public ID (may be year, month, day, hour, minute, second, second or less, or a combination thereof). This information is only in the case of the flowchart illustrated in FIG.
In step S206, the mail notification module 125 notifies the disclosure destination user (the user of the disclosure destination PC 190) of the URL with the temporary publication ID.

  FIG. 3 is a flowchart illustrating an example of the download process. A flow (first flow) from when a user who has received an e-mail (a user of the disclosure destination PC 190) accesses a URL in the e-mail to when a document is downloaded will be described. When publishing a document, a URL based on a temporary publication ID is issued once, and a password is set at the timing when the notification destination user accesses the URL. Furthermore, a URL based on a regular public ID that can be actually downloaded at that timing is issued, and an e-mail notification is sent again to the same notification destination as the e-mail address sent first.

In step S302, the disclosure destination PC 190 accesses the URL in the e-mail delivered to the external user by the operation of the external user.
In step S304, the public information control module 110 determines whether the access (current) is within the public period. If it is within the period, the process proceeds to step S306, and if it is out of the period, the process proceeds to step S322. In other words, the document management server 100 identifies the public ID from the URL, and confirms the public period of the public information associated therewith. If it is within the public period, the process proceeds to step S306. If it is outside the public period, an error is displayed (step S322) and the process ends.
In step S306, the public information control module 110 determines whether or not a password has been set. If it has not been set, the process proceeds to step S308, and if it has been set, the process proceeds to step S314.
In step S308, since a password setting screen is displayed on the external user's disclosure destination PC 190, the password is set by the operation of the external user.

In step S310, the public information control module 110 associates the set password with the publicly issued public ID and regenerates and stores the public information. Specifically, public information is newly generated in response to a password setting based on an operation of an external user. At this time, each information of the public information is set as follows.
-Public ID: A new unique value is generated.
-Password: Set based on external user operation.
-Target document ID: Copy the target document ID of the public information associated with the temporary public ID.
-Public period: Copy the public period of the public information associated with the temporary public ID.
In step S312, the e-mail notification module 125 sends e-mail notification to the public user of the URL with the regular public ID. Then, after notifying the public user of the new URL with the regular public ID, the document management server 100 waits until the user accesses the new URL. Then, the process returns to step S302.

In step S314, a password input screen is displayed on the external user's disclosure destination PC 190, and the password is input by the operation of the external user. If a password is set in step S306, a password input screen is displayed on the external user's disclosure destination PC 190, and the input password is acquired.
In step S316, the public information control module 110 determines whether or not the passwords match. If they match, the process proceeds to step S318, and if they do not match, the process proceeds to step S320. The document management server 100 confirms whether the input password matches the password set in the public information. If they match, the process proceeds to step S318. If they do not match, an error is displayed (step S320) and the process ends.
In step S318, the public information control module 110 sends a document (content) to the public PC 190 of the external user. A document (content) is acquired from the target document ID of the public information, downloaded to the public PC 190 based on the operation of the external user, and the process ends.
In step S320, the public information control module 110 displays an authentication error message on the external user's public PC 190.
In step S322, the public information control module 110 displays a public expiration date message on the external user's public destination PC 190.

  FIG. 4 is a flowchart illustrating an example of download processing. A flow (second flow) from when a user who has received an e-mail (a user of the disclosure destination PC 190) accesses a URL in the e-mail until a document is downloaded will be described. Here, apart from the expiration date of the publication itself, an expiration date is provided for the regular URL, and the expired regular URL is now treated as a temporary URL, and the same processing is repeated.

In step S402, the publishing destination PC 190 accesses the URL in the e-mail delivered to the external user by the operation of the external user.
In step S404, the public information control module 110 determines whether the access time (current) is within the public period, and if it is within the period, the process proceeds to step S406, and if it is outside the period, the process proceeds to step S424. In other words, the document management server 100 identifies the public ID from the URL, and confirms the public period of the public information associated therewith. If it is within the public period, the process proceeds to step S406. If it is outside the public period, an error is displayed (step S424) and the process ends.
In step S406, the public information control module 110 determines whether a password has been set. If it has not been set, the process proceeds to step S408, and if it has been set, the process proceeds to step S414.
In step S408, since a password setting screen is displayed on the external user's disclosure destination PC 190, the password is set by the operation of the external user.

In step S410, the public information control module 110 associates the set password with the publicly issued public ID and regenerates and stores the public information. Set an expiration date for the public ID. Specifically, public information is newly generated in response to a password setting based on an operation of an external user. At this time, each information of the public information is set as follows.
-Public ID: A new unique value is generated.
-Password: Set based on external user operation.
-Target document ID: Copy the target document ID of the public information associated with the temporary public ID.
-Public period: Copy the public period of the public information associated with the temporary public ID.
-Expiration date of public ID: The date and time calculated by adding a predetermined time to the current date and time.
In step S412, the e-mail notification module 125 sends e-mail notification to the publishing destination user of the URL on which the regular public ID is placed. Then, after notifying the public user of the new URL with the regular public ID, the document management server 100 waits until the user accesses the new URL. Then, the process returns to step S402.

  In step S414, the public information control module 110 determines whether or not the validity period of the public ID has expired. If it has expired, the process proceeds to step S408, and if it is within the period, the process proceeds to step S416. That is, at the time of access (current), it is confirmed whether the expiration date of the public ID recorded in the public information has passed.

In step S416, a password input screen is displayed on the external user's disclosure destination PC, and the password is input by the operation of the external user. If a password is set in step S406, a password input screen is displayed on the external user's disclosure destination PC 190, and the input password is acquired.
In step S418, the public information control module 110 determines whether or not the passwords match. If they match, the process proceeds to step S420, and if they do not match, the process proceeds to step S422. The document management server 100 confirms whether the input password matches the password set in the public information. If they match, the process proceeds to step S420. If they do not match, an error is displayed (step S422) and the process ends.
In step S420, the public information control module 110 sends a document (content) to the public PC 190 of the external user. A document (content) is acquired from the target document ID of the public information, downloaded to the public PC 190 based on the operation of the external user, and the process ends.
In step S422, the public information control module 110 displays an authentication error message on the external user's public PC 190.
In step S424, the public information control module 110 displays a public expiration date message on the external user's public destination PC 190.
Note that the processes of steps S402 to S408, step S412, and steps S416 to S424 are equivalent to the processes of steps S302 to S308, step S312, and steps S314 to S322 in the flowchart illustrated in FIG.

Hereinafter, based on the flowchart illustrated in FIG. 4, specific processing will be described using examples of the display screen of the document publication setting PC 170 and the publication destination PC 190, the data structure used in the document management server 100, and the like.
In the present embodiment, it is a precondition that an electronic document (attribute information and content) is stored in advance in the database 145 and the file storage 150 of the document management server 100 in a state that can be uniquely identified by the document ID. .
In the database 145, for example, a document information storage table 500 is stored. FIG. 5 is an explanatory diagram showing an example of the data structure of the document information storage table 500. The document information storage table 500 includes a document ID column 510, a version column 520, a document name column 530, a type column 540, a content information column 590, and the like. The document ID column 510 stores a document ID. The version column 520 stores the version of the document. The document name column 530 stores the document name of the document. The type column 540 stores the type of the document (such as the type of application that can handle the document). The content information column 590 stores content information (an address such as a file path where the contents of a document are stored).

A specific example from when the login user (user of the document publication setting PC 170) first performs the document publication operation to when the first electronic mail is sent to the publication destination (publication destination PC 190) will be described along the flow. The process in the flowchart illustrated in FIG. 2 will be described with reference to FIGS.
(1, Step S202) A logged-in user inputs necessary information and requests publication of a document.
The logged-in user inputs the following information and requests the publication of the document (selection of the OK button 652). FIG. 6 is an explanatory diagram showing a processing example according to the present embodiment. The required disclosure information input screen 600 has a target document input area 610, a mail address input area 620, a disclosure period input area 630, an OK button 652, and a cancel button 654. The required disclosure information input screen 600 is presented on a display device such as a liquid crystal display of the document disclosure setting PC 170.
-Document to be published (target document input area 610)
-Public mail address group (mail address input area 620)
-Publication period (publication period input area 630)

(2, Step S204) A temporary public ID is issued for each public destination, and public information is stored in association with it. FIG. 7 is an explanatory diagram showing an example of the data structure of the public information storage table 700 and the relationship between the document information storage table 500 and the public information storage table 700.
The public information storage table 700 has a public ID column 710, a password column 720, a target document ID column 730, a public period 740, and a public ID expiration date column 750.
-Public ID (Public ID column 710): An identifier for uniquely specifying public information.
-Password (Password field 720): A password for downloading a document (content) from this public information. It is empty at this point.
-Target document ID (target document ID column 730) ... This is an identifier for specifying the target document.
-Publication period (publication period 740): This is a period during which the target document can be downloaded from the publication destination.
-Expiration date of public ID (public ID expiry date column 750): Date and time when document content cannot be downloaded with public information of public ID.
For example, from the first row of the document information storage table 500, public information on the first and second rows of the public information storage table 700 is generated for each notification destination (two in this example).

(3, Step S206) The URL with the temporary public ID is notified to the public user (public PC 190) by e-mail.
FIG. 8 is an explanatory diagram showing a processing example according to the present embodiment. An e-mail is generated from the first line of the public information storage table 700 and transmitted to the public PC 190B (user of the public PC 190B), and an electronic mail is generated from the second line of the public information storage table 700, It is transmitted to the disclosure destination PC 190A (the user of the disclosure destination PC 190A). Then, for example, “△△ Function Specification.docx has been released as the mail contents 810 of the e-mail to be sent to the destination PC 190B. Please access the following URL: http: //aaa.bbb.ccc .co.jp / application / j7fjY8r7jsxcudKeo23i "is described. Note that “ΔΔ functional specification. Docx” is extracted from the document name column 530 of the document information storage table 500. The final part of the URL is extracted from the public ID column 710 of the public information storage table 700.

A specific example from the access to the URL in the e-mail until the document is downloaded in the flowchart illustrated in FIG. 4 will be described with reference to FIGS. .
(1, Step S402) Based on the operation of the external user (the user of the disclosure destination PC 190), the URL received by e-mail is accessed. FIG. 9 is an explanatory diagram showing a processing example according to the present embodiment. The URL in the e-mail is described in the URL designation field 920 in the browser upper part 910 where the browser 900 is enlarged and displayed.
(2, Step S404) It is confirmed whether it is within the public period.
-The document management server 100 side specifies a public ID from the URL, and confirms a public information disclosure period associated therewith. Specifically, the last part of the URL in the URL designation column 920 is extracted, and the row corresponding to “public ID column 710 of the public information storage table 700” is extracted. If the access time (current time) is within the disclosure period, the process proceeds to (3). If it is outside the release period, an error is displayed and the process ends.

(3, Step S406) It is confirmed whether a password for public information is set. FIG. 10 is an explanatory diagram showing a processing example according to the present embodiment. Specifically, the password field 720 of the public information storage table 700 (in this example, the password field 720 on the first line of the public information storage table 700) is confirmed, and if it is empty, that is, not set (5 ) If set, go to (4).

(4, Step S414) It is confirmed whether the expiration date of the public ID recorded in the public information has passed. FIG. 11 is an explanatory diagram showing a processing example according to the present embodiment. Specifically, in (3), a password is set in the password field 720 of the public information storage table 700 (in this example, the password field 720 on the third line of the public information storage table 700). The public ID expiry date column 750 of the public information storage table 700 (in this example, the public ID expiry date column 750 in the third row of the public information storage table 700) is extracted, and when accessed (current time), It is determined whether it is within the expiration date. If it has passed, go to (5). Instead of returning to the flow illustrated in FIG. 2, it is not necessary to issue a new temporary public ID by proceeding to (5). That is, the number of public IDs issued is reduced. If not, go to (8).

(5, Step S408) Since the password setting screen is displayed on the external user's disclosure destination PC 190, the external user himself / herself sets the password. FIG. 12 is an explanatory diagram showing a processing example according to the present embodiment. The browser 1200 has a password setting area 1250, and a password input field 1255 and an OK button 1260 in the password setting area 1250. A password is input in the password input field 1255, the OK button 1260 is selected, and the password is set.
(6, Step S410) The public information is regenerated and stored by associating the set password with the publicly issued public ID. Also, an expiration date is set for the public ID.
・ New public information is generated in response to external user password settings. That is, a regular public ID is generated. Specifically, a new line (in this example, the third line) is added to the public information storage table 700. And each information of public information is set as follows.
-Public ID (Public ID column 710) ... A new unique value (regular public ID) is generated.
-Password (password field 720): This is set by an external user (in this example, the password set in the password entry field 1255).
-Target document ID (target document ID column 730) ... The target document ID of the public information associated with the temporary public ID is copied (in this example, the content of the target document ID column 730 on the first line is the target on the third line) Copy to document ID column 730).
-Publication period (publication period 740) ... The public information public period associated with the temporary public ID is copied (in this example, the contents of the public period 740 in the first line are copied into the public period 740 in the third line). .
-Expiration date of public ID (public ID expiry date field 750): The date and time calculated by adding a predetermined time to the current date and time. However, the expiration date is checked so as not to exceed the period set in the disclosure period 740. When the period set in the publication period 740 is exceeded, a display indicating that a publication ID is issued again (that is, returning to the flow illustrated in FIG. 2) may be performed.

(7, Step S412) The URL on which the regular public ID is placed is notified to the public user by e-mail. After the notification, the server side waits until the user accesses a new URL. Return to (1).
FIG. 13 is an explanatory diagram showing a processing example according to the present embodiment. An e-mail is generated from the third row of the public information storage table 700 and transmitted to the public PC 190B (the user of the public PC 190B). Then, for example, “△△ Function Specification.docx has been released as the mail content 1310 of the e-mail to be sent to the publishing destination PC 190B. Please access the following URL: http: //aaa.bbb.ccc .co.jp / application / 9Uiduwe73kcep83kGdif "is described. Note that “ΔΔ functional specification. Docx” is extracted from the document name column 530 of the document information storage table 500. The final part of the URL is extracted from the public ID column 710 on the third line of the public information storage table 700.

(8, Step S416) A password input screen is displayed on the external user's disclosure destination PC 190 to prompt the user to input the password. Then, the input password is acquired. FIG. 14 is an explanatory diagram showing a processing example according to the present embodiment. The browser 1400 has a password setting area 1450, and the password setting area 1450 has a password input field 1455 and an OK button 1460. When a password is input in the password input field 1455 and the OK button 1460 is selected, the password is acquired.
(9, Step S418) Check whether the passwords match. That is, the server side confirms whether the entered password matches the password set in the public information. Specifically, the password entered in the password input field 1455 and the value in the password field 720 of the public information storage table 700 (here, the public ID field 710 of the public information storage table 700 corresponding to the final part of the URL is 3 Since it is the line, it is determined whether or not the password field 720) of the third line matches. If they match, go to (10). If they do not match, display an error and exit.

(10, Step S420) The document content is sent to the public PC 190 of the external user. That is, the content of the target document is acquired from the target document ID of the public information, downloaded to the external user (public destination PC 190), and the process ends. Specifically, a document in the downloadable document display area 1570 is selected by an operation of an external user, and the document is downloaded.
FIG. 15 is an explanatory diagram showing a processing example according to the present embodiment. The browser 1400 is presented with the downloadable document display area 1570 added to the example illustrated in FIG. In this example, the document ID column 510 (first row) of the document information storage table 500 corresponding to the target document ID column 730 of the third row of the public information storage table 700 is specified, and the content information column 590 of the first row. Is reflected in the downloadable document display area 1570. When the downloadable document display area 1570 is selected, the document (document in the content information column 590 of the document information storage table 500) is downloaded.
