Description

Mail function providing apparatus, method, program

The present invention relates to a mail function providing apparatus which displays a mail interface and allows a user to use a mail.

2. Description of the Related Art Conventionally, e-mail software such as Microsoft's Outlook Express (registered trademark) is used to display an e-mail interface to provide and use e-mail functions for computer users.

For example, Patent Document 1 discloses electronic mail software. In this e-mail software, the user sets a keyword and a character string of an e-mail address. Then, when the mail is sent, it is determined whether the set character string is included in the mail. Then, if it is determined to be included, a warning is displayed to the user. By this display, it is possible to prevent an inappropriate transmission such as an email containing a set keyword being erroneously sent to the set address.

Japanese Patent Laid-Open No. 2002-207672

However, according to the e-mail software of the conventional patent document 1, even though the administrator of the computer wants the appropriate transmission to be performed, the transmission may be improper. In other words, if the user who sends e-mail is not conscious to send e-mail properly, the setting is deleted, the setting is inappropriate, and other e-mail software other than the e-mail software described in Patent Document 1 is used. If you do, you will be sent inappropriately.

Also, simply by being warned, the user can not understand why such a warning is given, can not raise the user's awareness sufficiently and reliably, the warning can be ignored, and the warning is displayed. And inappropriate transmissions may be repeated.

The present invention has been made in view of the above points, and when mail is transmitted, it is possible to reliably prevent inappropriate transmission regardless of the circumstances of the user side, and furthermore, the user's The purpose is to be able to raise awareness.

That is, according to the present invention, it is possible to display more appropriate content, to be surely displayed, and to have a simple configuration in the display at the time of the determination of a violation that is an inappropriate transmission. The purpose is to be compatible with the display.

In order to solve the above-mentioned subject, the present invention adopts the following composition.

That is, a web mail function providing unit that causes a web browser of a computer to display a web mail interface and causes a user of the computer to use the web mail, and a rule in which transmission of the web mail performed by the web browser is predetermined. Is held when a judgment unit for judging whether or not the information is violated, a wording specific data storage unit for storing wording specific data for specifying the wording of the rule, and the judgment unit by the judgment unit And a display control unit configured to display the wording specification data on the web browser.

Here, the wording specification data is data for specifying a character string indicating a rule wording, and is a main body of the character string or a link (pointer) to a storage area in which the character string is stored. The specified character string is, for example, a character string of the form “don't do B in the case of A”, “must do the D in the case of C”, or the like.

Also, “display the wording specification data on the web browser” means displaying the wording specified by the wording specification data on the web browser. The display control unit may display the word immediately now. In addition, the display control unit displays a link to the wording, and when the displayed link is clicked, displays the wording of the displayed link, and displays the wording later than the present time. It is also good.

Then, the storage unit stores a file such as Excel (registered trademark), Access (registered trademark), Word (registered trademark), etc. created by the user and in which the rule wording, the article number, etc. are stored as the wording specification data. Remember.

Then, the display control unit acquires the term specific data by searching the stored Excel file or the like, and displays the acquired term specific data.

In addition, the wording specific data (for example, the file of Excel etc.) which can display the character string which is a word of a rule are memorize | stored by the wording specific data storage part. On the other hand, determination of the rule is performed by the determination unit. When the violation is determined, the display control unit acquires, as data to be used for display, the wording specific data stored in the storage unit rather than the simple warning character string or the like. The text of the rule is displayed by displaying the text specific data. As a result, better data can be displayed as data to be displayed when determining a violation.

In other words, it is not a mere warning, but a persuasive basis for explaining that the transmission is inappropriate, the wording of the rule regarding the violation is displayed, and the user's awareness of the transmission being inappropriate It can be enhanced reliably, sufficiently and quickly.

In addition, a special storage unit for storing special data is not newly required, and appropriate display can be performed using mere wording specification data, and more suitable display can be performed with a simple configuration.

Moreover, with this configuration, the software such as Outlook Express that allows the user to easily change the operation can display the wording with the web browser of the webmail instead of displaying the wording. As a result, regardless of the circumstances of the user, it is possible to ensure that display can be performed to prevent inappropriate transmissions that violate the rules.

Note that, for example, regardless of whether or not special software is installed on the user's computer, it is possible to surely display an appropriate display.

As a result, even if the mail system is provided in an organization system used in an organization such as a company, the following advantages are realized. That is, at this time, many users with low awareness of appropriate transmission are included among the users. In spite of this, it is possible to prevent improper transmission reliably and to make it possible to raise awareness to perform appropriate transmission easily and quickly. As a result, even if there is a low-conscious user, for example, a user who does not know the rule or a user who is late for knowing the rule, the user can use the mail in the organization system.

Irrespective of the circumstances on the user side, it is possible to prevent inappropriate transmission of e-mails from being performed, and to increase awareness that adequate and reliable transmission should be performed.

Further, more appropriate data can be acquired as data to be displayed when the determination of a violation is made, and the acquired more appropriate data can be displayed.

For example, the web mail server apparatus 11 implements the function of the web mail server 100 in the web mail server apparatus 11 by executing predetermined software stored in the web mail server apparatus 11. A portion of this software may be known software, such as, for example, known software that processes Internet Message Access Protocol (IMAP).

For example, the web mail server apparatus 11 includes an information processing unit 11a and an information storage unit 11b. The information processing unit 11 a includes, for example, a CPU (Central Processing Unit) of a computer built as the web mail server apparatus 11. The information processing unit 11a processes operations and other information. The information storage unit 11 b includes, for example, all or part of a random access memory (RAM), a read only memory (ROM), a hard disk drive (HDD), a solid disk drive (SDD), or the like included in the computer. The information storage unit 11 b stores information. The web mail server apparatus 11 functions as a computer by operating the hardware, that is, the information processing unit 11a and the information storage unit 11b. The web mail server apparatus 11 thereby realizes the function of the web mail server 100 in the web mail server apparatus 11. The information storage unit 11 b may store, for example, the above software. The information processing unit 11a (and the information storage unit 11b) executes control of the web mail server apparatus 11 to realize the function of the web mail server 100 by executing the stored contents of the software.

Note that the information processing unit 11 a and the like of the web mail server device 11 shown in FIG. 2 are merely an example. That is, each computer with which the in-company system 1 is equipped, such as the employee computer 12, for example, includes the information processing unit 11a of the computer.

Here, each of the functional blocks (FIG. 2 etc.) of each part of the web mail server 100, the web mail server 100, etc. may be a functional block of a function by an object. That is, each functional block may be, for example, a functional block of a function realized by an object generated by the web mail server 100 executing software. Here, an object is an object in object orientation. For example, these objects may be objects implemented by an object-oriented language such as JAVA (registered trademark), PHP (Hypertext Preprocessor), JavaScript, ruby, or the like (each registered trademark).

The employee computer 12 is a computer included in the in-house system 1, such as a personal computer, which is used by the user 12 u who is an employee belonging to the company of the in-house system 1. The employee computer 12 implements the function of the web browser 200 by executing the software of the web browser. In the employee computer 12, for example, software of a web browser is installed.

The web mail server 100 is a functional block of the web mail server realized by the web mail server apparatus 11. The web mail server 100 causes the web browser 200 of the employee computer 12 to display a web mail interface 201 and provides the user 12 u with a web mail function.

The web mail server 100 is, for example, a web application that operates on the function of the web server implemented by the web mail server apparatus 11. The web server may be, for example, Apache. For example, the web mail server 100 may be a web application implemented by software such as PHP (Hypertext Preprocessor) or JAVA (registered trademark) installed on a web server. A part of the webmail server 100 may be constructed by known webmail technology. Technologies to be used include, for example, GMAIL (registered trademark, http://www.gmail.com), which is a web mail service of Google, and Yahoo Mail (http://mail.yahoo.co. A technique equivalent to the technique included in jp) may be used.

In addition, about the part which may be implement | achieved by well-known technology among the in-company systems 1, description is abbreviate | omitted about the detailed structure of the part suitably. The in-house system 1 includes systems in which various configurations are adopted in a detailed configuration in which the description is omitted. For example, the in-house system 1 includes a system in which the detailed configuration without description includes a system configured according to a known technology, a system configured according to a new future developed technology, and a technology that will become common in the future Including systems configured according to

The web browser 200 of the employee computer 12 is a functional block of the web browser function implemented by the employee computer 12. The web browser 200 displays the web mail interface 201 to the user 12 u. The interface 201 is an interface that the web mail server 100 causes the web browser 200 to display. The web browser 200 may be, for example, a conventional web browser. More specifically, for example, the web browser 200 may be Internet Explorer (registered trademark), Fire Fox (registered trademark), or Safari (registered trademark). , May be another web browser.

The other computers in the in-house system 1 other than the employee computer 12, such as the other employee computers 13 and the other employee computers 14, are the same computers as the employee computer 12, and the description thereof will be omitted as appropriate.

The in-house rule R is a rule established by a company when an employee such as the user 12 u uses web mail. The user 12 u is obliged to observe the company rule R when using web mail using the employee computer 12. The in-house rule R is provided, for example, as information of a booklet in which the in-house rule R is printed, from the company to each employee such as the user 12 u.

The rule server device 15 stores in-house rule data Re in which the in-house rule R is recorded in the form of electronic data. The in-house rule data Re is data of the wording of each rule included in the in-house rule R. Then, when the web browser 200 opens the URL of each stored rule, for example, by working as a web server, the rule server device 15 causes the web browser 200 to display the wording of the in-company rule of the URL. . The rule server device 15 may be configured by, for example, a personal computer. More specifically, the rule server device may be configured by a general-purpose personal computer. The in-house rule data Re is, for example, a file such as Excel or Access. The in-house rule data Re may be a simple text file.

In the in-house system 1, instead of the two separate server devices of the web mail server device 11 and the rule server device 15, one server device having the functions of the web mail server device 11 and the rule server device 15 together May be provided. One or both of the web mail server device 11 and the rule server device 15 may be interpreted as functional blocks of functions implemented in the in-house system 1.

FIG. 2 is a diagram showing the detailed configuration of the web mail server 100 (FIG. 1).

The web mail server 100 includes a mail data acquisition unit 111, a determination unit 300, a violation processing unit 400, and a determination log management unit 500 (see FIGS. 17 to 20 and the like).

Although not shown in FIG. 2, the web mail server 100 also includes a charging display control unit 119 and the like shown in FIG. 32.

The mail data acquisition unit 111 acquires mail data from the web browser 200. Specifically, the mail data acquisition unit 111 acquires mail data when the user 12 u transmits a mail by the interface 201 that the web mail server 100 causes the web browser 200 to display. That is, when transmitting the e-mail, the e-mail data acquisition unit 111 acquires from the web browser 200 e-mail data that the web browser 200 causes the web e-mail server 100 to execute the transmission. The mail data acquisition unit 111 may be understood to include the basic functions of the web mail server 100. For example, the mail data acquisition unit 111 causes the web browser 200 to display a web mail interface, and causes the user 12 u to use the web mail.

The mail data includes the address of the mail to be sent, the text of the mail, an attached file, and the like. Here, the e-mail destination includes the destination in the To column, the destination in the Cc column, and the destination in the bcc column. Also, the mail data includes sender identification data that identifies the sender of the mail. Here, as the sender identification data, the user 12 u of the employee computer 12 of the transmission source of the sender identification data is set by the web browser 200 as a sender identified by the sender identification data. Specifically, the sender identification data is the sender's personal ID. Also, in the mail data, whether the operation of the user whose creation of the mail has been started is a new mail creation operation, an operation to reply a mail, or a forwarding operation to forward the email. Includes start operation data specifying which operation was or which operation was.

In addition, at least a part of the mail data is held by, for example, a mail server of the external company 2 (FIG. 1) in the external mail server apparatus 11 or a destination mail box in the Web mail server apparatus 11. By this, the mail of the mail data is sent to the destination of the mail by the mail data.

The mail data acquisition unit 111 may also acquire mail data by a known communication method in a WEB application, for example. For example, the mail data acquisition unit 111 causes an interface such as a send button to be displayed on the web browser 200, and when the interface is clicked, the mail data is transmitted by the employee computer 12 to the web mail server 100. Make it The mail data acquisition unit 111 acquires mail data by displaying this interface. The send button is an interface through which the user 12 u inputs an operation such as a click to cause the web mail server 100 to send the created mail. Then, the e-mail data acquisition unit 111 causes the web browser 200 to display a send button or the like to be transmitted by, for example, HTTP (HyperText Transfer Protocol) communication, and acquires e-mail data from the web browser 200 by HTTP communication. . The HTTP communication is a general communication as communication performed by the web browser to the web mail server in the web application.

The web browser 200 transmits the webmail to the user 12 u of the employee computer 12 executing the web browser 200 by specifying the user who is logging in as the sender with respect to the provided webmail function, for example. Identify as a person. Login to web mail is performed using, for example, an employee ID.

The determination unit 300 analyzes the mail data acquired by the mail data acquisition unit 111 to make a determination. More specifically, the determination unit 300 has the functions of the following parts, and performs analysis and determination using the functions of the parts as described in detail below.

That is, the determination unit 300 includes the rule determination condition master DB (DB: database) 311 (FIG. 3), the transmission destination domain master DB 312 (FIG. 9), the organization master DB 313 (FIG. 8), and the approval history DB 314 (FIG. 23). And a determination processing unit 320.

FIG. 3 is a diagram showing the configuration of the rule determination condition master DB 311 (FIG. 2) and the rule identification information DB 411 (FIG. 2).

The rule determination condition master DB 311 holds feature data of the rule code in association with a rule code for specifying each of the plurality of rules included in the in-house rule R (FIG. 1, FIG. 2). The feature data indicates the feature of the mail data when transmission by the user 12 u is performed in violation of the rule of the rule code corresponding to the feature data. Here, the rule code is, for example, the number assigned to each rule, or the item number of the rule among the item numbers of a plurality of rules of the in-house rule R.

The characteristic data is, in the table of the rule determination condition master DB 311 shown in FIG. 3, each row of character string to target operation in each column such as R001, that is, the second to seventh rows (the second row from the top It is indicated by the 7th line). That is, as shown in FIG. 3, the feature data is character string data (line 2), department ID (line 3), transmission destination identification data (line 4), and start operation data (5th line). And 7 lines). String data specifies a string such as "idiot" included in mail. The department ID is an ID of a department to which the sender of the mail belongs among a plurality of organizations such as divisions making up a company, and is an ID such as H001, for example. The sender identification data is data such as “outside” that specifies the destination of the mail. The start operation data specifies, out of the three operations of new creation, reply and transfer, the user operation whose creation of the mail has been started. Then, the feature data specifies the following mail data as the mail data having the feature of the feature data. That is, the feature data specifies that the transmission of the mail by the specified mail data is a transmission that violates the rule of the feature data. The email data to be identified includes the character string identified by the character string data in the text of the email, and the department identified by the department ID is the department to which the sender of the email belongs, and The operation specified by the start operation data is mail data which is an operation at which creation of the mail is started.

The rule determination condition master DB 311 may store a file having the above data structure as mail data, for example, in a memory (information storage unit 11 b) such as the main storage of the web mail server apparatus 11. In addition, the rule determination condition master DB 311 is a virtual storage unit, and stores a file having the above data structure and the like in a predetermined actual storage device outside the web mail server apparatus 11. It is also good. Then, when the virtual storage unit is accessed from the outside of the rule determination condition master DB 311 to the virtual storage unit, the virtual storage unit generates an access to a real storage device corresponding to the access, and the virtual storage unit is virtualized. Write and read may be realized in the access to the general storage unit. The same applies to other DBs other than the rule determination condition master DB 311, storage units, and the like.

Whether the mail data acquired by the mail data acquisition unit 111 (FIGS. 3 and 2) has the feature data feature for each of the feature data items held in the rule determination condition master DB 311 It is determined whether or not. That is, the determination processing unit 320 determines whether transmission of the mail by the acquired mail data is transmission in violation of a rule related to the feature data.

Specifically, the determination processing unit 320 determines whether the character string of the feature data is included in the acquired mail data. Further, the determination processing unit 320 determines whether the department of the feature data is the department of the sender of the mail data. Further, the determination processing unit 320 determines whether the transmission destination of the feature data is the transmission destination of the mail data. In addition, the determination processing unit 320 determines whether the operation of the feature data is the operation of the mail data.

Then, the determination processing unit 320 determines that the mail data includes the character string of the feature data, determines that the department is the department of the feature data, and the transmission destination is the transmission destination of the feature data. If it is determined that the operation is the operation of the feature data (if the violation condition is satisfied), it is determined that a violation occurs. That is, when the violation condition is satisfied, the determination processing unit 320 determines that the mail data is mail data that violates the rule of the feature data, that is, transmission of the mail violates the rule. judge.

Conversely, whether the determination processing unit 320 determines that a character string is not included, determines that a department is not a department of feature data, or determines whether a transmission destination is not a transmission destination of feature data Alternatively, if it is determined that the operation is not the operation of the feature data (if the violation condition is not satisfied), it is determined that the operation is not a violation. That is, in this case, the determination processing unit 320 determines that the mail data is not a violation mail data.

In the case where the feature data does not include a character string, that is, when the feature data consists of only a department or the like, the determination processing unit 320 determines whether the violation is or not based on only the result of the department determination. Do.

In addition, the determination processing unit 320 performs the determination using the organization master DB 313, for example, as specifically described with reference to FIG. Further, the determination processing unit 320 performs the above determination regarding the transmission destination using, for example, the transmission destination domain master DB 312 as specifically described in FIG. 9. However, the in-house system 1 is not limited to a system that performs these determinations using the organization master DB 313 and the destination domain master DB 312, and is a system that does not use one or both of the organization master DB 313 and the destination domain master DB 312. It may be.

It should be noted that, in order to perform the above-described determination relating to the operation, for example, whether the operation specifying data (described above) included in the mail data specifies the same operation as the start operation data included in the feature data It is judged whether or not it is judged.

Among the plurality of parts of the determination unit 300 shown in FIG. 2, parts other than the parts described above, for example, the part such as the approval history DB 314 will be described in detail later.

The violation processing unit 400 (FIG. 2) includes a rule identification information DB 411 (FIGS. 3 and 4), an accident case information DB 412, an avoidance method information DB 413, an in-house rule display control unit 421, and an accident case display control unit 422. , An avoidance method display control unit 423, a confirmation processing unit 431, and an approval processing unit 432 (FIG. 23).

FIG. 4 is a diagram showing a more detailed configuration of the rule identification information DB 411 (FIG. 2, FIG. 3).

The rule identification information DB 411 holds the URL. The held URL is a URL (Uniform Resource Locator) that causes the rule server device 15 to display the wording of the rule on the client as a web server by being transmitted to the rule server device 15. More specifically, the rule identification information DB 411 holds, for each rule code (see the description of FIG. 3), a URL in which the rule of the rule code is displayed. In FIG. 4, the held URLs are illustrated in the link destination (base information) column of the third column of the table of FIG. 4.

When the determination processing unit 320 determines that the rule is violated, the in-house rule display control unit 421 (FIGS. 2 and 4) causes the link to the URL to acquire the mail data for which the determination is made. It is displayed on the web browser 200. Specifically, in this case, the internal rule display control unit 421 applies the rule to the rule code that the rule determination condition master DB 311 (FIG. 3) associates the feature data (FIG. 3) for which the determination of the violation is made. A link to the URL that the specific information DB (FIG. 4) associates is displayed. As a result, the internal rule display control unit 421 causes the rule server device 15 to display the violated rule on the web browser 200, that is, to display the wording of the violated rule and display the displayed word Let 12u view it.

The details of the screen on which the in-house rule display control unit 421 causes the link to be displayed will be described in detail later with various variations (FIG. 7 and the like).

If the user 12 u of the web browser 200 clicks a send button for sending a mail, for example, the in-house rule display control unit 421 causes the web mail server 100 to display the web browser next to the page on which the clicked send button is displayed. A link is displayed on the page displayed on 200.

FIG. 5 is a flowchart showing the flow of processing performed by the in-house system 1.

In step S121, the web browser 200 transmits the mail data to the web mail server 100.

In step S111, the mail data acquisition unit 111 acquires (receives) the mail data transmitted in step S121.

Then, the web mail server 100 performs the processing of step S112 and step S11a for each of the feature data held in the rule determination condition master DB 311 (FIG. 3). For example, the feature data includes data of importance, and the web mail server 100 performs this processing in order from processing of feature data including data of higher importance.

In step S112, the determination processing unit 320 determines whether the mail data acquired in step S111 violates the rule of the feature data as described above.

Then, if it is determined in step S112 that no violation occurs (step S112: determination of conformity), the in-house rule display control unit 421 causes the web browser 200 to display the link to the URL of the rule described above ( The process for the feature data ends without performing step S114 described later).

In step S113, when it is determined in step S112 that the rule of the feature data is violated (step S112: violation determination), the internal rule display control unit 421 (FIG. 2) determines the URL of the rule corresponding to the feature data. Is acquired from the rule identification information DB 411 (FIG. 4).

In step S114, the in-house rule display control unit 421 causes the link to the URL acquired in step S113 to be displayed.

In step S124, the web browser 200 displays the page of the link displayed by the in-company rule display control unit 421 in step S114, and in the page when the link is clicked, the wording of the rule in which the violation is determined Display. In step S124, for example, when the user 12u does not click the link, the web browser 200 does not display this, and the processing of FIG. 5 ends.

Note that, for example, the web mail server 100 may perform the processing of the above-described steps S112 to for each of the plurality of stored feature data.

FIG. 6 is a diagram showing the mail M. The mail M in FIG. 6 is a mail in which the user 12 u enters the addresses of a plurality of domains of the company 2 (FIG. 1) in the Cc column (not shown), and thereby two different transactions of those domains. It is an email for requesting a quote for the same one product to the destination company.

The details of the in-house system 1 described above will be described using the mail M in FIG. 6 as an example.

In step S112, when the mail data of the mail M in FIG. 6 is acquired, the determination processing unit 320 sends the mail of the mail data in the rule of the feature data of the rule code R008 in FIG. It is determined to violate (step S112: determination of violation). Here, the feature data of the rule code R 008 specifies the transmission destinations of the destinations of the addresses of a plurality of domains, as indicated by the “multiple to outside company” symbol in FIG. For this reason, since the determination processing unit 320 determines that the transmission destination indicated by the acquired e-mail data is the transmission destination specified by the feature data of the rule code R008, the e-mail transmission with the e-mail data is performed according to the rule code R008. Determine that it is a violation of

Therefore, in step S113, the in-house rule display control unit 421 acquires the URL of the rule code R008, and in step S114, the in-company rule display control unit 421 causes the interface 201 to display a link to the acquired URL. Display the wording of the rule of rule code R008.

FIG. 7 is a view showing the web browser 200 in a state in which a link RL to a rule is displayed and in a state in which a rule word Rx is displayed, on the left of FIG. 7 and the right of FIG.

The web browser 200 on the left side of FIG. 7 is the web browser 200 in a state in which the internal rule display control unit 421 displays the link RL to the URL of the rule code R008 in step S114 (step S114). The in-house rule display control unit 421 causes the web browser 200 to display the link RL of the URL of the rule for which a violation has been determined (step S112: violation determination), for example, as shown in the state on the left of FIG.

The web browser 200 on the right of FIG. 7 is a diagram showing a rule statement Rx that the web browser 200 causes the web browser 200 to display when the link RL in the state on the left of FIG. 7 is clicked. Here, the wording Rx of the displayed rule is the wording of the above-mentioned rule code R 008 for which the violation has been determined.

Thus, the web mail server 100 causes the user 12 u to browse the displayed rule text Rx. This indicates to the user 12 u that the rule is included in the in-house rule R and explains that the transmission of the mail M (FIG. 6) is inappropriate. Indicated.

(Organization master DB 313, transmission destination domain master DB 312)
FIG. 8 is a diagram showing the configuration of the organization master DB 313 (FIG. 2).

FIG. 9 is a diagram showing the configuration of the destination domain master DB 312 (FIG. 2).

The organization master DB 313 (FIG. 8) associates and holds, for each department of a company, an organization code (department code) for specifying each department and personal IDs of a plurality of employees who belong to the department.

Then, the determination processing unit 320 specifies the organization code that the organization master DB 313 associates the same personal ID as the personal ID of the sender identification data included in the mail data with the organization code of the department to which the sender belongs, Identifies the department as the department to which the sender belongs. The determination processing unit 320 determines whether the section of the sender thus identified is the section of the feature data (FIG. 3) and determines whether the mail data has the feature of the feature data. (Step S112 in FIG. 5: violation determination).

The transmission destination domain master DB 312 (FIG. 8, FIG. 9) is the transmission destination identification data and the transmission destination identification data for each of the transmission destination identification data (described above) held by the rule determination condition master DB 311 (FIG. 3). Holds the correspondence with the domain name included in the e-mail address of the destination specified by. For example, as shown in FIG. 9, the transmission destination domain master DB 312 associates and holds transmission destination identification data and a sender's domain name identified by the transmission destination identification data. The transmission destination domain master DB 312 may associate and hold transmission destination identification data and data of a regular expression for identifying the domain name of the sender identified by the transmission destination identification data.

Then, the determination processing unit 320 specifies the transmission destination of the e-mail address having the domain name that the transmission destination domain master DB 312 associates with the transmission destination specification data included in the feature data, and the transmission destination specified by the transmission destination specification data. Do. Then, the determination processing unit 320 determines whether the email address included in the email data is the email address of the transmission destination identified by the feature data identified in this way, and determines whether the email data is a violation email or not Determination (step S112 in FIG. 5).

(Determination processing unit 320)
FIG. 10 is a flowchart showing details of the process of determination by the determination processing unit 320 in step S112 of FIG.

Details of the process of determination by the determination processing unit 320 in step S112 of FIG. 5 will be described with reference to FIG.

In step S21, the determination processing unit 320 determines whether the text of the mail data includes the character string of the feature data. For example, the determination processing unit 320 performs this determination by searching whether or not the character string is included in the text.

In step S22, when it is determined that the character string is included in step S21 (step S21: included), the determination processing unit 320 determines whether the department of the transmitter is the same as the department of the feature data. Determine if As described above, in this determination, for example, the organization master DB 313 is used.

In step S23, when it is determined that the departments are the same in step S22 (step S22: match), the determination processing unit 320 determines whether the transmission destination of the mail data is the transmission destination of the feature data. Do. As described above, in this determination, for example, the destination domain master DB 312 (FIG. 9) is used.

In step S24, when it is determined in step S23 that the transmission destination is the transmission destination of the feature data in step S23 (step S23: matches), the operation of the mail data is the operation of the feature data. It is determined whether or not they match. The details of this determination are, for example, as described above.

In step S25a, when it is determined that the violation condition is not satisfied (step S21: not included, S22: not matched, S23: not matched, S24: not matched) in FIG. It is determined that the transmission of the mail by the mail data acquired in step S111 does not violate the rule of the feature data (step S112 in FIG. 5: conformity determination). In this case, it is specified that no character string is included (step S21: not included), or that a group is not identical (step S22: not matched), or the transmission destination is This is either the case where the transmission destination of the feature data is specified (step S23: no match), or the case where the operation is not specified match (step S24: no match). .

In step S25b, when the determination processing unit 320 determines that the violation condition is satisfied (step S21: included, S22: match, S23: match, S24: match) in step S111 of FIG. It is determined that the transmission of the mail by the mail data acquired in the step violates the rule of the feature data (Step S112 in FIG. 5: violation determination). In this case, it is determined that a character string is included (step S21: included), and it is determined that the departments are the same (step S22: match), and the transmission destination is the transmission destination of the feature data. This is a case where it is specified that there is a certain (step S23: match), and it is determined that the operation matches (step S24: match).

(Processing part 400 at the time of violation)
Next, the details of the violation process performed by the violation process unit 400 in step S11a of FIG. 5 will be described.

Characters may be included or sounds may be included.

The accident case display control unit 422 (FIG. 2) determines the accident case information of the rule relating to the violation from the accident case information DB 412 when the violation is determined (step S112 of FIG. 5: violation determination, step S25b of FIG. 10). The acquired and acquired accident case information is displayed on the web browser 200. More specifically, the accident case display control unit 422 acquires, from the accident case information DB 412, accident case information that the accident case information DB 412 associates with the rule code corresponding to the feature data for which the violation has been determined. Display the accident case information that has been

The avoidance method information DB 413 (FIG. 2) holds the method of transmission without violating the rule, that is, the avoidance method information specifying the evasion method for avoiding the violation by the rule. More specifically, the evasion method achieves the intended purpose not to be achieved by the transmission of the mail determined to be a violation, by transmitting data such as the transmission of the mail in a manner not to violate the determined rules. It is a method. A concrete example of the avoidance method will be described in detail later. For example, the avoidance method specifically includes a method of transmitting an encrypted e-mail, and a method of delivering an attached file by means other than e-mail. The avoidance method information DB 413 holds the avoidance method information of the rule of the rule code in association with each of the plurality of rule codes. The avoidance method information may be various information as long as it is information that allows the user 12 u to recognize the avoidance method when it is displayed by the web browser 200 and can use the recognized avoidance method. A URL for using the method may be included. The URL may be a URL for launching application software for using the method.

The avoidance method display control unit 423 (FIG. 2), when the violation is determined (step S112 in FIG. 5: violation determination, step S25 b in FIG. 10), the avoidance method associated with the rule code for which the violation is determined. Information is acquired from the avoidance method information DB 413, and the acquired avoidance method information is displayed on the web browser 200.

In step S31 (FIG. 11), the in-house rule display control unit 421 (FIG. 2) determines from the rule identification information DB 411 the violation determination (step S112 in FIG. 5: violation determination, step S25 b in FIG. 10). Get URL

In step S32, the in-house rule display control unit 421 causes the web browser 200 to display the wording of the rule held by the rule server device 15, using the URL acquired in step S31. Specifically, the internal rule display control unit 421 acquires the wording of the rule from the rule server device 15, transmits the acquired wording of the acquired rule to the web browser 200, and displays the transmitted wording of the rule You may Also, for example, the internal rule display control unit 421 transmits the URL to the web browser 200 as the URL of the page to be displayed by the web browser 200 inside the frame included in a part of the page displayed on the web browser 200. May be Then, the in-house rule display control unit 421 may display the wording of the rule in the frame in the web browser 200 by this transmission.

The web browser 200 on the left side of FIG. 12 is the web browser 200 having a state in which the in-house rule display control unit 421 displays the rule word Rx in step S32.

Note that, for example, if the predetermined setting is made to the web mail server 100 by, for example, the user 12 u, the internal rule display control unit 421 displays the link (link RL) as shown in FIG. 7. Instead, as shown by the web browser 200 in the state shown in the left side of FIG.

In step S33 (FIG. 11), the accident case display control unit 422 acquires, from the accident case information DB 412, the accident case information of the rule in which the violation is determined.

In step S34, the accident case display control unit 422 causes the interface 201 to display the accident case information acquired in step S33.

The web browser 200 in the center of FIG. 12 is the web browser 200 having a state in which the accident case display control unit 422 displays the accident case information Ex in step S33.

As shown by the displayed accident case information Ex in FIG. 12, the accident case information is a basis for explaining that the transmission is inappropriate, and specifically, that the rule is valid. It is the basis to explain and information that is the purpose.

In the accident case display control unit 422, accident case information such as a button (refer to the web browser 200 in the left state of FIG. 12) or the like in which characters such as "watch accident case" are described in step S32 described above, for example. The interface for displaying may be displayed in the page on which the in-house rule display control unit 421 displays the rule. Then, when the user 12 u inputs an instruction to display accident case information to the web mail server 100 through the interface by clicking the button or the like, the accident case display control unit 422 causes an accident in step S 34. Case information may be displayed. Then, as shown by the broken arrow on the left side in FIG. 12, the accident case display control unit 422 specifically changes the page to be displayed from the page to another page. The accident case information may be displayed on the page.

In step S35, the avoidance method display control unit 423 acquires the avoidance method information of the rule from the avoidance method information DB 413.

In step S36, the avoidance method display control unit 423 causes the web browser 200 to display the avoidance method information acquired in step S35.

The web browser 200 on the right of FIG. 12 is the web browser 200 in a state in which the avoidance method display control unit 423 displays the avoidance method information Ax in step S36.

The display of the avoidance method information may be performed in the same manner as the display of the accident case information described above. That is, in step S34 described above, the avoidance method display control unit 423 displays an interface for displaying the avoidance method information, such as a button (refer to the center in FIG. 12) in which characters such as "next" are described. It may be displayed in some way. Then, the avoidance method display control unit 423 displays the avoidance method information in step S36 when the user 12 u inputs an instruction to display the avoidance method information through the interface by, for example, the button being clicked. May be Then, as shown by the broken arrow on the right side in FIG. 12, the avoidance method display control unit 423 specifically changes the page to be displayed from the page to another page. The accident case information may be displayed on the page.

In this example, the accident case display control unit 422 causes the accident case display control unit 422 to display the accident case information after the in-house rule display control unit 421 causes the rule wording to be displayed, and the avoidance method display control unit 423 performs the avoidance method after the display. Display the information (see FIG. 12). As another example, after the in-house rule display control unit 421 causes the rule wording to be displayed, the avoidance method display control unit 423 causes the avoidance method information to be displayed, and after the indication, the accident case display control unit 422 causes an accident case. Information may be displayed. Further, after the avoidance method display control portion 423 displays the avoidance method information, the in-house rule display control portion 421 causes the wording of the rule to be displayed, and after the display, the accident case display control portion 422 causes the accident case information to be displayed.

May be Each of these display orders allows for the display of information that produces an effect corresponding to that order.

(Internal rules)
FIG. 13 shows the web browser 200 in each state of displaying the mail M violating the rule regarding the secret information (left) and displaying the link RL to the rule violating the mail M (right). It is a figure shown on the left and FIG. 13 right, respectively.

The mail M on the left side of FIG. 13 includes the character string “secret” of the character string data included in the feature data of the rule of the rule code R 004 shown in FIG. That is, transmission of the mail M is transmission that violates the rule of the rule code R004.

When the mail data of the mail M on the left side of FIG. 13 is acquired (step S111 of FIG. 5), the determination processing unit 320 determines that the internal rule of the rule code R004 is violated (step of FIG. 5). S112: violation determination, step S25b of FIG. Therefore, the in-house rule display control unit 421 causes the web mail interface 201 to display the link to the URL of the rule of the rule code R004 as the link RL on the right of FIG. 13 (step S114 in FIG. 5 and step in FIG. 11). S32).

As for the setting to display the link to the rule wording described above or to directly display the rule wording (see the description of step S32 in FIG. 11), any setting is made hereinafter. In the case where it is clear that the description of the process at the time of reading is obvious, the detailed description is appropriately omitted.

The in-house system 1 may be configured to perform only the process of displaying the link without performing such setting, or may employ the configuration of performing only the process of directly displaying the wording of the rule.

FIG. 14 shows the web browser 200 in two states: a state (left) in which the mail M violating the rules regarding the slander is displayed (left) and a state (right) in which the link RL to the rule is displayed. It is.

The mail M on the left side of FIG. 14 includes the same character string as the character string “idiot” of the character string data included in the feature data of the rule of the rule code R006 shown in FIG.

When the mail data of the mail M on the left side of FIG. 14 is acquired (step S111 of FIG. 5), the determination processing unit 320 determines that the internal rule of the rule code R006 is violated (step of FIG. 5). S112: violation determination, step S25b of FIG. Therefore, the in-house rule display control unit 421 causes the web mail interface 201 to display the link to the URL of the in-company rule of the rule code R006 as the link RL on the right of FIG. 14 (step S114 in FIG. 5, FIG. Step S32).

FIG. 15 shows the web browser 200 in two states, the state (left) displaying the mail M violating the in-company rule regarding the transmission destination and the state (right) displaying the link RL to the rule. FIG.

E-mail M on the left side of FIG. 15 is an e-mail in which the user with the personal ID “1000000” is a sender. The personal ID “1000000” is a personal ID that the organization master DB 313 (FIG. 8) associates with the department ID H001 of the feature data of the in-house rule of the rule code R003 shown in FIG. The sender's personal ID of the rule.

Also, in the mail M on the left side of FIG. 15, the domain of the destination mail address is domainA.xx. The domain domainA.xx is a domain that the destination domain master DB 312 (FIG. 9) associates with the destination D02 of the feature data of the rule code R003 described above, and is the domain of the feature data.

When the mail data of the mail M on the left side of FIG. 15 is acquired (step S111 of FIG. 5), the determination processing unit 320 determines that the rule of the rule code R003 is violated (step S112 of FIG. 5). : Violation determination, step S25 b of FIG. Therefore, the in-house rule display control unit 421 causes the web browser 200 to display the link to the URL of the rule of the rule code R003 as the link RL on the right of FIG. 15 (step S114 in FIG. 5 and step S32 in FIG. 11).

More specifically, as described above, the in-house system 1 performs the display of the determination of the violation, the display of the link to the word of the rule for which the determination of the violation has been made, and the display of the word of the rule.

(Processing on the second violation)
The process of the in-house system 1 will be described in more detail.

FIG. 16 is a flowchart showing a specific example of the violation process performed by the violation process unit 400 in step S11a of FIG. In step S11a of FIG. 5, for example, the process of FIG. 16 is performed in addition to the above process.

The rule determination condition master DB 311 (FIG. 3) holds type specification data that specifies the type of the rule of the rule code, which is associated with each rule code. Types identified include: bans, cautions, warnings.

In step S41, when a violation is determined (step S112 in FIG. 5: violation determination, step S25 b in FIG. 10), the violation processing unit 400 identifies the type associated with the rule code for which the violation is determined. It is determined whether the type specified by the data is prohibited.

In step S42, when it is determined in step S41 that the type is not prohibited (step S41: caution / warning), the violation processing unit 400 determines whether to display a link or an in-house rule. For example, the violation process unit 400 determines that the rule determination condition master DB 311 is to be displayed when the predetermined flag associated with the rule code is on (step S42: display), and is off. , It is decided not to display (step S42: not displayed). The detailed configuration of the flag may be, for example, a configuration based on known technical knowledge.

In step S43, when it is determined in step S41 that the type is prohibited (step S41: prohibited), the in-violation processing unit 400 determines whether to display a link or an in-house rule. For example, also in this case, the violation process unit 400 makes a determination based on the above-described flag.

In step S421, when it is determined to be displayed in step S42 (step S42: display), the violation processing unit 400 determines the type of type identification data associated with the rule code for which the violation has been determined. Is displayed. In step S421, the violation processing unit 400 displays, for example, characters of “warning message” shown on the web browser 200 on the left side of FIG. That is, in step S421, the time of violation processing unit 400 causes the character for displaying the type to be displayed in the title of the page on which the link or the wording of the rule is displayed. Note that the character displayed when the type is a warning may be, for example, the character of "attention" in the web browser 200 on the right of FIG.

The rule identification information DB 411 (FIG. 4) holds the message associated with the rule code of each rule code (second column in FIG. 4).

Then, in step S421, the violation process unit 400 causes the interface 201 to display a message associated with the violated rule code. Specifically, for example, when the violating rule code is R099 shown in FIG. 4, the in-violation processing unit 400 displays a message to be held to display “Warning! "To, Cc, there are multiple domains outside the company ..." to display the message.

Although not illustrated in FIG. 7 and the like, the violation processing unit 400 may cause the interface 201 to display an OK button and a cancel button in step S421. The displayed OK button is a button for the web mail server 100 to transmit a mail of the acquired mail data when it is clicked. The cancel button is a button for the web mail server 100 to cancel transmission when clicked.

In step S422, when it is determined not to display (step S42: not displayed) in step S42, the violation processing unit 400 does not display the link (or the word of the rule) as described above, but simply does not display it. Only the display of the type of violation, the display of the held message, and the display of the two buttons of the send button and the cancel button are performed (not shown).

In step S423, the web mail server 100 (violation processing unit 400) transmits the mail of the acquired mail data when the OK button displayed in step S421 or step S422 is clicked.

In step S431, when it is determined in step S43 that the violation processing unit 400 is to display (step S43: display), the type of violation is displayed, that is, the display object such as a character indicating prohibition is displayed. Display. In addition, in step S431, the violation process unit 400 causes the message and the link (or the wording of the rule) to be displayed.

Then, in step S431, the in-violation processing unit 400 does not display the cancel button but displays only the OK button. The displayed OK button is merely a button that the user 12 u clicks when it is confirmed that transmission is a violation, and is not a button for executing transmission. The violation processing unit 400 cancels the transmission by preventing the transmission of the OK button not to be displayed in step S 431 (step S 433).

In step S432, the violation process unit 400 causes the type of violation, the message, and the OK button to be displayed when it is determined in step S43 not to display (step S43: not displayed). The processing at the time of violation 400 prevents the transmission even in step S432 and cancels the transmission (step S433).

In step S 433, the violation process unit 400 performs a process for canceling transmission, that is, discards prepared data such as prepared data for transmission, secured memory area, and generated object. In step S433, the violation processing unit 400 causes the web browser 200 to display an interface for editing the mail having a state of starting editing the mail whose transmission has been canceled, and the transmission is canceled. You may start (resume) editing of the mail.

(Determination log management unit 500)
As shown in FIG. 2, the determination log management unit 500 includes a determination log DB 501 and a determination log display control unit 502.

FIG. 17 is a diagram showing the configuration of the determination log DB 501.

The determination log DB 501 generates determination log data, and holds the generated determination log data after the generation. This generation is performed each time transmission is determined to be a violation by the determination processing unit 320 (FIG. 17, FIG. 2) (step S112 in FIG. 5: violation determination, step S25 b in FIG. 10). The judgment log data to be generated includes the time when the judgment of the violation corresponding to the generation was made, the sender identification data (personal ID) of the sender of the mail for which the determination was made, and the type identification data of the determination rule And the rule code of that rule.

FIG. 18 is a flowchart showing a specific example of the process (refer to the web browser 200 in the state on the right of FIG. 12) performed by the avoidance method display control unit 423 (FIG. 17, FIG. 2) in step S3a of FIG. As described above, the process of FIG. 11 is the process of step S11a in FIG. Therefore, the process of FIG. 18 is the process of step S11a of FIG.

In step S51, the avoidance method display control unit 423 determines whether or not the following determination log data is included in the plurality of determination log data held in the determination log DB 501. That is, in step S51, the avoidance method display control unit 423 determines the personal ID of the sender of the mail data for which the violation has been determined in step S112 immediately before step S11a of FIG. 5 including the process of FIG. It is determined whether or not the determination log data of the rule code thus included is included.

That is, in step S51, the avoidance method display control unit 423 determines whether or not determination log data indicating that determination of a violation regarding the same rule has been performed in the past is held for the same sender.

In step S52, the avoidance method display control unit 423 obtains the avoidance method information when it is determined that the determination of the violation for the same sender and the same rule has not been made in the past (step S51: Yes). (Step S35 in FIG. 11).

In step S53, the avoidance method display control unit 423 displays the information of the avoidance method acquired in step S52 (step S36 in FIG. 11).

On the other hand, when it is determined that the determination of a violation regarding the same sender and the same rule has been made in the past (step S51: No), the avoidance method display control unit 423 performs step S52 and step S53 (FIG. 11 (FIG. 11). The process of step S35 and step S36) is not performed, and the avoidance method information is not displayed. In step S51 at the time of the first violation in the past, it is determined that the same violation has not been made in the past (step S51: Yes), and the avoidance method information is displayed (steps S52 and S53).

For example, in step S53, the avoidance method display control unit 423 is configured not to display the “next” button illustrated in the web browser 200 in the center state of FIG. 12, and does not display the page in the state of FIG. Let's do it. Then, in step S53, the avoidance method display control unit 423 causes the “send as is” button and the “reedit” button in the right state to be displayed on the page in the center state of FIG.

In addition, there is also a case where the user 12 u has forgotten the avoidance method in step S 51: No (FIG. 18). Therefore, for example, even if the avoidance method display control unit 423 or the like causes the redisplay necessity button to be displayed, and the user 12 u makes the user 12 u input the necessity of the redisplay necessity by operating the displayed redisplay necessity button. Good. Then, the avoidance method display control unit 423 or the like may display the avoidance method when the operation desired to be redisplayed is input, and may not display the avoidance method when the operation is not input.

Also, the determination log DB 501 (FIG. 17) may be used as follows.

The determination log display control unit 502 (FIG. 17 and FIG. 1) causes the web browser 200 to display the information of each held determination log data.

FIG. 19 is a view showing the web browser 200 in a state of displaying the first violation history display Kv.

The first violation history display Kv is displayed by the determination log display control unit 502 in a page in which the in-company rule display control unit 421 displays a link similar to the page in the state of the web browser 200 on the left in FIG. It is an interface (display object). The first violation history display Kv indicates, for each type of violation, the number of judgment log data of that type held by the judgment log DB 501, that is, for each type of judgment of a violation of that type in the past Indicates the number of times.

Then, the determination log display control unit 502 displays such a first violation history display Kv, and displays the number of determinations of each type of violation.

FIG. 20 is a diagram showing the web browser 200 in a state of displaying the second violation history display Kv.

The web browser 200 on the left side of FIG. 20 is the web browser 200 having a state for displaying the main screen 201 m (main page) of web mail. The main screen 201m has various icons such as an icon of mail inbox (mailbox), an icon of a sent folder for saving sent mail, and a variety of icons such as an icon of a draft folder for saving drafts and saved in the inbox Contains a list of each email. In addition, in FIG. 20, each icon is illustrated by the character string which shows the icon. In this list, for example, in the state shown in FIG. 20, the destination is Tanaka, the sender is in the middle, the transmission / reception date is 4/25 of the E-mail column, the destination is Kimura, the sender is Wada, the transmission / reception date is 5 Contains multiple email fields, such as the / 11 email field. Then, this list includes selection columns which are highlighted by hatching, are highlighted, and are selected by the user 12 u by clicking or the like in the list of FIG. Then, the content of the mail in such a selection column is displayed on the web browser 200 when instructed by the user 12 u by, for example, clicking a button in which “E-mail content display” is written in FIG. Be done. The main screen 201 m is an interface that allows the user 12 u to select an e-mail whose content is to be displayed.

The web mail server 100 displays such a main screen 201 m on the left side of FIG. Then, the web mail server 100 displays the button 201 mb in the main screen 201 m. The button 201 mb is a button for causing the determination log display control unit 502 to display the second violation history display Kv on the web browser 200. For example, when the button 201mb is clicked, the determination log display control unit 502 displays the second violation history display Kv.

The web browser 200 in the state shown in the right of FIG. 20 is the web browser 200 having the state in which the determination log display control unit 502 causes the second violation history display Kv to be displayed when the button 201mb in the left state is clicked. .

Here, the page displayed by the web browser 200 in the state shown in the right side of FIG. 20 on which the second violation history display Kv is displayed is account information for causing the web mail server 100 to display various information of the user 12 u in use. It is a display screen. The web mail server 100 identifies, for example, that the user in use is the user 12 u from the login name input at the time of login to the web mail server 100, and information of the user 12 u identified as the user in use is identified. , To be displayed on this account information display screen. The displayed information of the user 12u is, for example, as shown in the page in the right state of FIG. 20, the user's name, mail address, remaining capacity of the inbox folder, charging information using web mail And so on.

The determination log display control unit 502 causes the second violation history display Kv to be displayed in such a page. The second violation history display Kv performs, for example, the same display as the display performed by the first violation history display Kv in FIG.

(Execution process of workaround method)
FIG. 21 is a view showing the web browser 200 (left) displaying the rule wording Rx and the web browser 200 (right) displaying the execution button Ae1 and the execution button Ae2 of the method for avoiding the rule. is there.

The page in the state of the right of FIG. 21 displays information of two avoidance methods for the rule of the wording Rx of the first avoidance method information Ae1 v and the second avoidance method information Ae2 v.

Then, as illustrated in FIG. 21, the rule of the rule word Rx in FIG. 21 is that the user 12u receives an approval from an approver, such as the superior of the user 12u or an administrator, for example, and transmits the mail. It is a rule that defines what must be done.

Then, in the first avoidance method, as shown in the first avoidance method information Ae1v on the right of FIG. 21, the mail or the attached file included in the mail is encrypted and the encrypted attachment is encrypted. It is a method by which application of this rule is avoided by being sent.

On the other hand, a second avoidance method is a method of avoiding by transmitting after the user 12 u receives an approval for the mail to be sent.

The first execution button Ae1 has a position corresponding to the position of the first avoidance method information Ae1v, and corresponds to the first avoidance method information Ae1v, and when the first execution button Ae1 is clicked, the avoidance method display control unit 423 Is a button for performing processing for executing the first avoidance method. Specifically, the avoidance method display control unit 423 performs, for example, an encryption process as this process.

The user 12 u clicks the first execution button Ae 1 and causes the avoidance method display control portion 423 having the avoidance method display control portion 423 to execute the processing, thereby using the process to be performed. To carry out.

The execution button Ae1 may be a button for the employee computer 12 to execute the first avoidance method such as encryption instead of the avoidance method display control unit 423 when the execution button Ae1 is clicked.

Thus, the avoidance method display control unit 423 displays the following when displaying the avoidance method information in an appropriate case, for example, when the predetermined avoidance method execution setting is set to the web mail server 100. Such processing may be performed. That is, at this time, the avoidance method display control portion 423 has an interface (first execution button Ae 1, 2nd) for causing the avoidance method display control portion 423 to execute processing for implementing the avoidance method of the avoidance method information to be displayed. The execute button Ae2) may be displayed together with the displayed avoidance method information.

(Approved)
Then, when displaying information on a plurality of avoidance methods, the avoidance method display control unit 423 causes an interface for executing processing for each of the avoidance methods to be displayed.

The second execution button Ae2 (FIG. 21) has a position corresponding to the position of the second avoidance method information Ae2v, and corresponds to the second avoidance method information Ae2v, and when clicked, the webmail The server 100 is a button that performs processing for the second avoidance method.

FIG. 22 is a view showing an approval notification 13M acquired by the web mail server 100 from another employee computer 13 (FIG. 1) used by the approver 13u.

Another employee computer 13 (FIG. 1) is a computer used by the approver 13 u.

The approval / non-approval notification 13M (FIG. 22) is, for example, a mail transmitted from the other employee computer 13 to the web mail server 100. Then, the approval / non-approval notification 13M is sent to notify the web mail server 100 that the approver 13u who is the user of the other employee computer 13 either approves or does not approve the transmission of the mail by the user 12u. The email is

Here, the approval notification 13M includes permission data (not shown) indicating whether to approve or not, and an approval code for specifying the transmission targeted by the approval notification 13M among the transmissions of each webmail. .

Note that the approval / non-approval notification 13M also includes a comment such as a comment prompting attention that the approver 13u conveys to the user 12u at the time of approval, which is shown as an approver comment column in FIG.

When the second execution button Ae2 (FIG. 21) is clicked, the approval processing unit 432 (FIG. 2) performs the following processing, for example, under the control of the avoidance method display control unit 423. That is, when the second execution button Ae2 is clicked, the approval processing unit 432 causes the web browser of the other employee computer 13 used by the approver 13u to display the approval notification 13M of the new approval code. By causing this display, the approval processing unit 432 causes the web mail server 100 to acquire the approval / non-authorization notice 13M transmitted by the approver 13u using the displayed interface 201.

The approval processing unit 432 causes the approver 13 u to edit the displayed approval notification 13 M by using the interface that the approver 13 u can edit to display the approval notification 13 M. As a result, the approval / non-authorization notification 13M in which the availability data or the like is set to an appropriate content by editing is acquired by the web mail server 100.

The approval processing unit 432 preferably displays information that is useful for the judgment of the approver 13 u as to whether or not to approve, in the approval notification or the like to be displayed. The displayed information may include, for example, the type of the rule, and may include an analysis result obtained by analyzing the mail to be approved by the web mail server 100 (above, three lines in FIG. 22). Information such as the text of the target mail, attached data, etc. may be included.

Then, the e-mail data acquisition unit 111 (FIG. 2) described above, for example, receives mail data when the execution button Ae2 (FIG. 21) of the second avoidance method is clicked, as notification 13M Is held by the web mail server 100 until it is acquired by the web mail server 100. Then, when the approval / non-authorization notice 13M is acquired by the approval processing unit 432, the mail data acquisition unit 111 is notified by the approval / non-approval notification 13M among the plurality of pieces of mail data held in the holding unit. Acquires mail data of mail from holding unit. For example, the holding unit holds the correspondence between the approval code and the mail data according to the approval code, and the mail data acquisition unit 111 corresponds to the same approval code as the approval code of the acquired approval notification 13M. Get mail data that the relationship corresponds.

Then, when the mail data acquisition unit 111 acquires the mail data of the acquired approval / non-approval notification 13M, the judgment processing unit 320 (FIG. 2) described above makes another judgment on the acquired mail data. If the acquired approval / non-approval notification 13M is a notification for approving transmission in this second determination, the determination processing unit 320 determines that the transmission is not a violation (step S112 in FIG. 5: conformity determination). Step S25a of FIG. 10, if it is a notification not approved, it is determined again that it is a violation (step S112 of FIG. 5: violation determination, step S25b of FIG. 10).

Then, the web mail server 100 determines that it is not a violation in the second determination (step S112 in FIG. 5: matching determination, step S25a in FIG. 10), and the first determination is regarded as a violation and transmitted. There was no sending of that email. On the other hand, if the web mail server 100 determines that a violation has been made in the second determination as well (step S112 in FIG. 5: violation determination, step S25 b in FIG. 10), the email is also used in the second determination. Will not be sent.

(Judgment on approval)
The other employee computer 13 (FIGS. 22 and 2) transmits the approval / non-authorization notice 13M to the web mail server 100 even when the execution button Ae2 (FIG. 21) of the second avoidance method is clicked. For example, the approver 13 u is verbally asked for approval by the user 12 u, creates an approval notification 13 M and sends it to the web mail server 100. At this time, the approval / non-approval notification 13M includes the personal ID (sender ID) of the sender of the mail to be approved, the personal ID of the approver 13u (hereinafter, the approver ID), and the availability data described above, Also includes the comments described above.

FIG. 23 is a diagram showing the configuration of the approval history DB 314 (FIG. 2).

The approval history DB 314 (FIG. 23, FIG. 2) indicates the time when the approval notification 13M is acquired, the sender ID of the mail data of the approval notification 13M, the approver ID, and the availability data (result data). Holds approval data consisting of comments, etc. The approval data may include an approval ID (not shown) in addition to the approval code. Although the approval data is not shown in FIG. 23, the approval data may also include specific data such as the subject of the mail to be approved for transmission and the subject of the destination according to the approval data.

Therefore, the approval data includes the sender ID, the approver ID, and the identification data such as the subject, and further includes approval target email identification data that identifies the target email from a plurality of emails.

Then, the approval history DB 314 generates approval data for the approval notification 13M each time the approval notification 13M is acquired, and holds the generated approval data thereafter.

The approval history DB 314 may include an acquisition control unit that acquires the approval notification 13M, and the web mail server 100 may acquire the approval notification 13M by the acquisition control unit.

FIG. 24 is a flowchart showing the process of determination of approval performed by the determination processing unit 320.

The processing in FIG. 24 is performed by the determination processing unit 320 in step S112 in FIG. Here, the process of FIG. 24 is performed, for example, between step S24 and step S25 b in the process of FIG. 10 in which the process of step S112 of FIG. 5 is performed, and it is determined that the operation matches in step S24. In the case (step S24: match), if the result of the process in FIG. 24 is a predetermined result (step S662 in FIG. 24), the violation is determined (step S25 b, step S112 in FIG. 5: violation determination). If the result is not a result (steps S661 and S663 in FIG. 24), it is a process to make a determination not a violation (step S25a, step S112 in FIG. 5: matching determination).

As shown in FIG. 3, the rule determination condition master DB 311 determines that transmission by the approver 13 u is required for transmission, and for example, approves the type of rule associated with a rule code such as the rule code R 007. Hold type identification data to identify.

The determination processing unit 320 executes the processing of FIG. 24 between step S24 and step S25b if the type identification data of the rule for determining the violation identifies the type of approval.

In step S61, the determination processing unit 320 determines whether the sender is a predetermined excluder. Here, the excluded person is, for example, an employee who does not receive approval, such as a company president or a director. Specifically, for example, the determination processing unit 320 holds excluder identification information for identifying the individual ID of the excluder, and the personal ID of the sender of the mail data is identified by the excluded person identification information held. It is determined whether the sender is an excluder by determining whether it is the sender of.

In step S663, when it is determined in step S61 that the sender is an excluder (step S61: Yes), the determination processing unit 320 determines that transmission is not a violation (step S25a (FIG. 10)). Step S112 in FIG. 5: Conformity determination). However, in step S663, the violation processing unit 400 causes the web browser 200 to display a warning indicating that the sender is not an excluder, indicating a violation. The approval processing unit 432 displays this warning, for example, at the timing of any one of the processes in step S11 a of FIG. 5.

In step S62, when it is determined in step S61 that the sender is not an excluded person (step S61: No), determination processing unit 320 is the same sender as the sender of the acquired mail data, and It is determined whether approval data indicating whether the approval data is to be approved is held by the approval history DB 314 or not.

In step S63, when it is determined in step S62 that the approval data satisfying the condition is held (step S62: Yes), the determination processing unit 320 determines the subject etc. specified by the identification data such as the subject of the approval data. It is determined whether or not the subject of the acquired mail data or the like.

In step S63, the determination processing unit 320 may determine whether or not the subject is the same or similar instead of determining whether the subject is the same or the like.

In step S64, when it is determined in step S63 that the same subject or the like is the same (step S63: Yes), the time of the approval data is a predetermined time from the current time. It is determined whether or not it is the time in the relatively new past. That is, in step S63, the determination processing unit 320 determines whether or not the time of the approval data is later than the past which is older by a predetermined time than the present.

In step S661, when it is determined that the time is relatively new in step S64 (step S64: Yes), it is determined that the transmission of the acquired mail data is approved by the approval notification 13M of the approval data.

In step S65, of the plurality of approval data held by the approval history DB 314, in step S62, the determination processing unit 320 determines that the transmission of the mail is not a target of approval by the approval data being processed. If it is (step S62: No, S63: No, S64: No), the following process is performed. That is, when it is determined that the approval data satisfying the above conditions relating to the sender or the like is not held (step S62: No), when it is determined that the same subject is not the same (step S63: No) If it is determined that the time is not a new time (step S64: No), the following process is performed. The processing to be performed is to execute the above-described processing of steps S62 to S64 with respect to approval data in which one employee belonging to the same department as the department to which the sender of the mail data belongs belongs and the selected employee is the sender. It is a process. Thus, the above-described steps S62 to S64 are repeated. Here, in step S65, the determination processing unit 320 specifies, by using the organization master DB 313, an employee who belongs to the same department among the respective employees, and selects the specified employee. Thereby, in the steps S62 to S64, if appropriate approval data is included in the plurality of approval data, it is identified (S64: Yes), and not included if not included (S64: S65: No).

In step S661, the determination processing unit 320 determines that the approval is not necessary when the determination of S64: Yes is made. Here, the case where the determination of S64: Yes is made means that when the approval by the approval data in which the selected employee is the sender is determined in Steps S62 to S64 at the time of repetition (Step S64: Yes) And, in the first steps S62 to S64, the case where the approval by the approval data to the sender of the mail to be approved is judged (step S64: Yes) is included. Thus, the determination processing unit 320 determines that the transmission does not violate the rule (step S112 in FIG. 5: conformity determination, step S25a in FIG. 10).

In step S662, when there are no remaining employees who can be selected in step S65 (step S65: No), the determination processing unit 320 transmits the mail of the mail data acquired this time as a new one. Determine that the required approval is required.

In step S65 described above, the determination processing unit 320 does not select the employee selected in each selection before the selection, while performing the selection repeatedly.

Then, if it is determined that the rule is violated (step S662), the determination processing unit 320 determines that the transmission is a violation (step S112 in FIG. 5: violation). Determination, step S25b of FIG.

Then, the avoidance method display control unit 423 determines, for example, that there is no approval (step S662), and the violation is determined (step S112 in FIG. 5: violation determination, step S25 b in FIG. 10). , The execution button Ae2 of FIG. 21 is displayed. Then, as shown in FIG. 22, the avoidance method display control unit 423 causes the other employee computer 13 to display an approval notice 13M for approving the transmission of the mail of the mail data, and the web mail server Allowing 100 to obtain approval notification 13M.

When the approval notification 13M is displayed on the other employee computer 13 in this way, a new approval ID is generated by, for example, the avoidance method display control unit 423 (FIG. 23, FIG. 2), etc. An approval / non-approval notification 13M may be displayed. Then, the holding unit of the mail data acquisition unit 111 described above may hold the correspondence that associates the mail data with the generated approval ID. Then, when the approval notification 13M is acquired from another employee computer 13, the holding unit uses the mail data associated with the approval ID of the acquired approval notification 13M as the mail data of the approval notification 13M. With regard to the identified and identified mail data, the process of the determination described above may be performed.

(Judgment of data volume)
Further, the determination processing unit 320 (FIG. 2) determines whether the transmission of the mail data of the mail data acquired by the mail data acquisition unit 111 violates the data amount rule.

Although not shown in FIG. 3, the rule determination condition master DB 311 has respective reference values such as the first prescribed value described below in association with the rule code of the rule related to the data amount. Feature data may be held.

When the violation of the data amount is determined, the violation processing unit 400 causes the web browser 200 to display a warning that the data amount is violated.

FIG. 25 is a flowchart showing the data amount determination process performed by the determination processing unit 320.

In step S71, the determination processing unit 320 determines that the post-multiplication data amount obtained by multiplying the data amount of the text of the email contained in the acquired email data by the number of destinations of the email is less than the first prescribed value. It is determined whether the

Note that the number of destinations is the number of destinations to which mail is sent. For example, the number of destinations described in the To column, the number of destinations described in the Cc column, and the number of destinations described in the bcc column And is the total number totaled.

The first prescribed value is, for example, an appropriate amount of data that can be accepted as an increase in the amount of data of text data stored in the in-house system 1. The first predetermined value is, for example, a value included in feature data as described above.

In step S72, when it is determined in step S71 that the amount of data is not less than the first specified value (step S71: No), the transmission of the mail is performed according to the data amount rule. Then, it is determined to violate the data volume rule of the text.

In step S73, the determination processing unit 320 determines whether the acquired e-mail data is data of an e-mail attached with attached data.

In step S74, when it is determined that the attached data is attached (step S73: Yes), determination processing unit 320 determines the amount of data of the attached data included in the acquired mail data. It is determined whether the amount of data after multiplication multiplied by the number of destinations of is smaller than a second predetermined value.

The second prescribed value is, for example, an appropriate amount of data that can be tolerated as an increase in the amount of data of attached data stored in the in-house system 1. The second predetermined value is, for example, a value included in feature data.

In step S75, when it is determined that the post-multiplication data amount is not less than the second predetermined value (step S74: No), transmission of the mail is performed according to the data amount rule. Determine that the data amount rules for attached data are violated.

The determination processing unit 320 may first determine whether the feature data is feature data of a data amount rule, for example, in step S112 of FIG. 5. Then, if the determination processing unit 320 determines that the data is the feature data of the data amount, it determines whether or not it is a violation by the process of FIG. 25 (step S112 of FIG. 5: violation determination / conformity determination, FIG. 10 without performing steps S25a and S25b) and performing the processing for determining whether or not a violation such as the processing of steps S21 to S24 of FIG. Good.

When the violation is determined in step S71 (step S71: No), the violation processing unit 400 displays, on the web browser 200, a warning display indicating that transmission violates the data amount rule of the text. Display. When the violation is determined in step S74 (step S74: No), the violation processing unit 400 displays a warning message indicating that transmission violates the data amount rule of attached data, as the web browser 200. Display on.

FIG. 26 is a view showing the web browser 200 in a state (left) displaying an email M violating a rule relating to a data amount and a state (right) displaying a link RL to the rule.

An E-mail M shown on the left of FIG. 26 is an E-mail attached with attached data of the attached document, and the post-multiplication data amount obtained by multiplying the data amount of the attached data by the number of destinations is equal to or more than the second specified value.

Therefore, when mail data of mail M on the left side of FIG. 26 is obtained, determination processing unit 320 determines that attached data is present in step S73 (step S73: Yes) and after multiplication in step S74. It is determined that the data amount is not less than the second specified value (step S74: No). Accordingly, in step S75, the determination processing unit 320 determines that the transmission of the mail M on the left in FIG. 26 violates the data amount rule of the attached data.

Therefore, when it is determined in step S75, the violation process unit 400 displays a page indicating that the transmission violates the data amount rule of attached data, as shown on the right of FIG. Among them, display a link RL to the rule.

Then, the avoidance method display control unit 423 displays an execution button (see the execution button Ae1 etc. in FIG. 21) of the avoidance method for avoiding the data amount rule (not shown). For example, the avoidance method display control unit 423 causes the link RL and its execution button to be displayed in the page displayed by the web browser 200 on the right side of FIG.

The execution button may be a button that, when clicked by the user 12 u, the web mail server 100 converts the attached data into a URL, and adds the URL holding the attached data to the mail to the mail. . Then, at the time of this addition, the web mail server 100 may delete the attached data from the mail, and may transmit the mail whose data amount is reduced by the addition and deletion.

Here, URL conversion is processing for causing the server for URL conversion to hold the data in advance and specifying the held URL from acquiring the server from the server etc. May be there.

When a mail that has been deleted, etc., is sent by the web mail server 100, the URL added is used by the device of the transmission destination, and the deleted attached data held by that device by the device is deleted. It is an email to be acquired.

In addition, when the execution button is clicked, the web mail server 100 specifies different timings having a predetermined time difference as transmission timings to a plurality of destinations, and the specified timings are identified. The button may be a button for performing transmission to the destination corresponding to that timing.

FIG. 27 is a diagram showing another example of the process of the web mail server 100 when it is determined that the rule of the data amount of attached data is violated (step S75 of FIG. 25).

In this example, the violation processing unit 400 may not display the execution button.

When the determination in step S75 of FIG. 25 is made, the violation process unit 400 causes the urgency of the mail and the post-multiplication data amount to exceed the second specified value, as indicated by the mail data. Depending on the amount, the processing corresponding to the emergency degree and the over amount is performed.

Here, the degree of urgency is a value or the like specified by the urgency degree specifying data, which is included in the mail, considered by the user 12 u, and which specifies the degree of urgency that the mail is to be transmitted.

In the case of high urgency, that is, from the top row of the table in FIG. 27, the violation processing unit 400 counts the second row and when the urgency is intermediate (second row). Makes some form of transmission.

First, the violation processing unit 400 performs normal transmission (the first row, first column) if the specified over amount is a small over amount that is less than or equal to the first reference amount. In addition, when the over amount is larger than the first reference amount, that is, when the over amount is in the middle to the large (in the second row, the third column of the first row) The data is converted into a URL, the URL converted into a URL is attached, and an email with the attached data deleted is sent.

In addition, when the degree of urgency is intermediate (line 2), the in-violation processing unit 400 performs the same process as that in the case where the degree of urgency is high, in principle. (2 lines, first column), to display a warning message on the web browser 200.

Further, when the degree of urgency is low (line 3), the violation processing unit 400 determines that the identified over amount is equal to or less than the second reference amount larger than the above-described first reference amount, that is, the over amount Is small to middle (the third column, the first column, the second column), the following processing is performed. The process to be performed is a process of displaying a warning message and performing transmission based on the above-described time difference. Further, when the specified amount of overrun is larger than the second reference amount (third column of the third line), the in-violation processing unit 400 causes the web browser 200 to display an interface for correcting the mail. Note that this interface is, for example, an interface for editing a mail, and is an interface for correcting the mail by making the editing. In addition, even when the amount of overrun is large (the third column of the third row), the in-violation processing unit 400 may perform transmission based on a time difference instead of performing such a display.

(Forbidden)
FIG. 28 is a flowchart showing a flow of processing when the determination processing of FIG. 10 (step S112 of FIG. 5) is performed for a rule regarding transfer prohibition.

The feature data of the rule code R002 held in the rule determination condition master DB 311 (FIG. 3) is the feature data of the transfer prohibition rule, and has character string data specifying the character string "transfer prohibited" It has start operation data that specifies an operation.

In step S81 (FIG. 28), the determination processing unit 320 determines whether the operation of the mail data is the operation of the feature data. Then, for example, the operation of the transfer prohibited feature data is only the transfer operation as indicated by the start operation specifying data of the feature data of the rule code R002 in FIG. 3, and the operation of newly creating and the operation of reply are included. Absent. Therefore, specifically, the determination processing unit 320 determines whether the mail data operation is a transfer operation and not a new creation operation and a reply operation.

The determination processing unit 320 may determine, for example, from the character string data included in the feature data, whether the feature data is transfer-prohibited feature data. Then, when it is determined that the feature data is transfer prohibition, the determination processing unit 320 switches the order of the process of step S24 of FIG. 10 and the order of the process of step S21. That is, in this case, the determination processing unit 320 performs the process of step S24 of FIG. 10 in the order of step S21, and performs the process of step S21 in the order of step S24. The process of step S81 of FIG. 28 is a part of the process of step S24 performed in the order of step S21 of FIG.

In step S 821, when the determination processing unit 320 determines in step S 81 that the transfer operation has been started (step S 81: based on the transfer operation), the transmitted mail indicated by the mail data is the feature data It is determined whether the character string of (1), that is, the character string prohibiting transfer in the rule code R002 is included.

The process of step S821 may be part of the process of step S21 performed in the order of step S24 of FIG.

In step S 831, when it is determined that the character string is included (step S 821: Yes), the determination processing unit 320 determines that the transmission of the acquired mail data is prohibited (FIG. 5). Step S112: Violation determination, Step S25 b of FIG.

Then, when it is determined in step S831, the violation processing unit 400 prohibits the transmission of the mail, that is, does not execute the transmission. This determination is the violation determination in step S112 in FIG. 5 (step S25 b in FIG. 10).

FIG. 29 shows the web browser 200 (left) having a state of displaying the mail M violating the transfer prohibition rule and the web browser 200 (right) displaying the link RL to the transfer prohibition rule. FIG.

A specific example of the process described above with reference to FIG. 28 will be described with reference to FIG.

The mail M in FIG. 29 includes the character string “transfer prohibited”, which is a character string of the rule code R002. Therefore, in the process of transmission of the mail M in FIG. 29, when the type of transmission is transmission by transfer operation (step S81 in FIG. 28: based on transfer operation), the determination in step S831 is made.

Therefore, the violation processing unit 400 prohibits the transmission of the mail M in FIG. 29, and displays the page of the web browser 200 in the state of the right in FIG. 29, and the internal rule display control unit 421 displays the page displayed. , The link RL of the rule of the rule code R002 (FIG. 3) is displayed.

In step S822, when it is determined that the character string is not included (step S821: No), the determination processing unit 320 determines whether the transferred e-mail to be transferred is an e-mail whose disclosure range is defined. Determine The email data includes the text of the email to be sent. Then, the forwarding mail is attached to the end of the text of the included mail. Therefore, the determination processing unit 320 specifies the transfer mail attached to the end of the text of the mail to be sent, and whether or not the specified transfer mail includes a portion defining the disclosure range. judge. That is, the determination processing unit 320 determines whether or not the disclosure range is specified by the mail data, and in other words, determines whether or not the disclosure range is defined.

In step S823, when it is determined that the disclosure range is not defined (step S822: No), the determination processing unit 320 determines whether the transfer e-mail is a limited e-mail. For example, if the mail header of the transfer mail includes a predetermined mail header indicating that the transfer mail is a limited mail, the determination processing unit 320 may determine that the mail is a limited mail. .

In step S832, when the determination processing unit 320 determines that the disclosure range is defined (step S822: Yes) and when it is determined that the disclosure mail is a limited mail (step S823: Yes), It is determined to give a warning (Step S112 in FIG. 5: violation determination, Step S25 b in FIG. 10).

Then, when it is determined in step S 832, the in-violation processing unit 400 causes the warning to be displayed by, for example, the in-house rule display control unit 421 although the transmission of the mail is executed. The warning to be displayed indicates that the transmission is transmission of a mail defining a disclosure range, or indicates transmission of a limited mail.

In step S833, when it is determined in step S823 that the mail is not the limited mail (step S823: No), the determination processing unit 320 determines that the transmission does not violate the rule (step S112 in FIG. 5: conforming). Determination, step S25a of FIG.

(Confirmation display)
FIG. 30 is a flowchart showing the web mail server process shown on the left of FIG. 5 in more detail.

Steps S111, S112, and S11a in FIG. 30 are as described in the description of FIG.

In step S94, the determination processing unit 320 selects the remaining feature data not processed in step S112 (see FIG. 5) among the plurality of feature data held in the rule determination condition master DB 311, If there is the feature data of and the selection is possible (step S94: Yes), the web mail server 100 is made to perform the processing of steps S112 to S11a for the selected feature data.

Such processing is as described above in the description of FIG.

In step S95, the confirmation processing unit 431 (FIG. 2) determines whether the mail transmission is canceled and not transmitted if there is no remaining feature data in step S94 and it can not be selected (step S94: No). Do.

FIG. 31 is a diagram showing a confirmation display F.

In step S96, when it is determined that transmission is to be performed (step S95: Yes), the confirmation processing unit 431 causes the web browser 200 to display a confirmation display F of transmission.

In step S96, the confirmation processing unit 431 displays the confirmation display F after all the display of the links and the rules, the display of the avoidance method information, and the display of the accident case information described above (see FIG. 11) are completed.

For example, when the mail M is transmitted, the confirmation processing unit 431 causes the web browser 200 to display the screen of the confirmation display F illustrated in FIG.

Then, as shown in FIG. 31, for example, the confirmation processing unit 431 displays a plurality of destinations of the transmitted mail in the confirmation display F, and causes the user 12 u to confirm again.

The left hexagon in FIG. 31 indicates the process of causing the confirmation processing unit 431 to display, and the right hexagon indicates the process of sending mail by the web browser 200.

(Billing)
FIG. 32 is a diagram showing the charging display control unit 119 and the like.

The web mail server 100 further includes a storage capacity acquisition unit 115, a charge determination unit 118, and a charge display control unit 119.

The storage capacity acquisition unit 115 is a data amount obtained by totaling the data amounts of all the data of the user 12 u held by the web mail server 100, such as mail of the user 12 u held by the web mail server 100. To get The storage capacity acquisition unit 115 may acquire the total data amount by calculating the total data amount from the data amount of each data held in the web server, for example.

Here, the amount of data acquired is an average amount when averaged over a predetermined period such as one month, for example, and is an amount of data on which a charge amount for the user 12 u holding data is specified. .

Here, the charge amount is, for example, an amount recorded as part of the cost of the user 12 u in company accounting. Then, the amount of charging is, for example, a larger amount as the average amount increases, as shown in the charging rate master DB of FIG.

Specifically, for example, even if the storage capacity acquisition unit 115 acquires an amount of data to be acquired by calculating an appropriate amount of data using the function of the operating system (OS) of the web mail server 100. Good.

The charge determination unit 118 determines whether the amount of data acquired by the storage capacity acquisition unit 115 has reached a predetermined amount of message data.

Here, the message data amount is set to an amount appropriate for the web browser 200 to cause the web browser 200 to display a billing message when the data amount reaches the message data amount. As will be described later, the message data amount is specified by specific data consisting of the data of the charging rate master DB 116 and the data of the management table 117 as a whole.

When it is determined that the data amount is the message data amount, the charging display control unit 119 causes the web browser 200 to display a charging message indicating that the data amount is the message data amount. For example, when the determination is made, the charging display control unit 119 causes the charging guidance message 201 n shown on the right web browser 200 of FIG. 32 to be displayed.

(Charging rate master DB 116 and management table 117)
Therefore, the message data amount will be described in more detail.

The web mail server 100 further includes a charging rate master DB 116 and a management table 117 (FIG. 32).

The charging rate master DB 116 holds the correspondence between the average amount of data and the amount of charging. For example, as shown in FIG. 32, the charge rate master DB 116 is a correspondence relationship in which 500 yen is associated with an average amount of 0 MB to 100 MB, and 1000 yen is associated with an average amount of 100 MB to 500 MB. Hold.

Here, the correspondence relationship held is a charge change point of 100 MB in which the amount of charge changes from 500 yen to 1000 yen, and a charge change point of 500 MB in which the amount of charge changes from 1000 yen to 2000 yen. Identify the charge change point where the amount of money changes.

Further, the charging rate master DB 116 holds, as an average amount of data amount of the user 12 u, an allowable limit data amount which is a limit permitted by the company. For example, as shown in FIG. 32, the charging rate master DB 116 holds an amount of data of 2 GB as an allowable amount of data.

The specific data amount includes the charge change data amount and the allowable limit data amount. The specific data amount is the data amount to be shown to the user 12 u when the data amount is in the vicinity of the data amount.

The charging rate master DB 116 specifies the data amount of the charging change point described above and the allowable limit data amount as the specific data amount.

The message data amount described above is the amount of data in the vicinity of the specific data amount. The neighborhood is the data volume of 105% from the data volume of 80% of the specific data volume. Here, the message data amount is the data amount of the 80% to 90% of the specific data amount, the data amount of the attention section, and the data amount of the warning section which is the 90% to 104% section. , The data amount of the section of the charging guide, which is a section of 104% to 105% (see the management table 117 of FIG. 32).

The charging rate master DB 116 specifies each specific data amount.

The management table 117 holds data in which each section of the specific data amount is specified from the specific data amount. The held data specifies the correspondence between the specific data amount and each section. Specifically, the held data specifies the range of the ratio of the data amount of the section to the specific data amount, such as 80% to 90% described above.

Then, the charging rate master DB 116 and the management table 117 as a whole specify the respective specific data amount by the charging rate master DB 116, and the specific data amount specified and the above-mentioned correspondence relationship. The data amount of each section corresponding to the data amount is specified. As a result, the charging rate master DB 116 and the like specify the amount of data in all of the sections in the specific data amount as the message data amount. Further, the charging rate master DB 116 or the like specifies the data amount of the part of each section as the data amount of the section among the message data amounts.

The charge determination unit 118 determines whether the data amount acquired by the storage capacity acquisition unit 115 is a message data amount. Then, when it is determined that the acquired data amount is the message data amount, the charging display control unit 119 displays a predetermined display. At this time, specifically, for example, among the plurality of specific data amounts, the charging display control unit 119 displays a display indicating which specific data amount the acquired data amount is the message data amount in, It may be displayed on the web browser 200. At this time, for example, the charging display control unit 119 may cause the web browser 200 to display a display indicating a section including the acquired data amount among a plurality of sections of the message data amount.

More specifically, these points are as follows, for example.

The management table 117 holds the correspondence between the specific data amount and the vicinity of the specific data amount. For example, as shown in FIG. 32, specifically, the vicinity specific data is the highest ratio 105% from the lowest data amount obtained by multiplying the specific data amount of the specific data by the lowest ratio 80% with respect to the specific data. Corresponds the neighborhood consisting of the highest data amount multiplied by. The management table 117 holds neighborhood specific data consisting of pairs of the lowest percentage 80% and the highest percentage 105%.

As a result, the management table 117 specifies the amount of data contained in the vicinity specified by the vicinity specifying data as the above-mentioned message data amount, specifically, from the minimum data amount of 80% of the specific data amount, Each data volume up to the maximum data volume% is specified as the message data volume.

The management table 117 also has section identification data for dividing the vicinity of the amount of money (charging change point etc.) into a plurality of sections corresponding to the type of message (attention, warning, charging guide). Specifically, as shown in FIG. 32, the section identification data specifies each of the sections by the lowest ratio and the highest ratio of the sections. The section identification data specifies an 80% to 90% proportion data amount section as the attention section, specifies a 90% to 104% proportion data amount section as the warning section, and charges As a section of guidance, a section of data volume with a rate of 104% to 105% is specified. The section identification data may be specifically configured by a range of ratios for identifying those sections.

When the amount of data acquired by the storage capacity acquisition unit 115 is 80% to 105% of the amount of any specific data, the charge determination unit 118 determines that the acquired amount of data is in the vicinity. It is specified (judged) that it is a data amount, that is, a message data amount.

Among the plurality of specific data amounts (data amount at charging change point, allowable limit data amount), the charging display control unit 119 includes the specific data amount in the vicinity of which the data amount acquired by the holding capacity acquiring unit 115 is included. If it is determined that there is, the accounting message is displayed.

Then, when it is specified (determined) that the data amount acquired by the storage capacity acquisition unit 115 is included in the vicinity of the specific data amount, the charge determination unit 118 divides the plurality of types of the vicinity thereof. In the above, the type of division in which the acquired data amount is included is specified. Types to be identified include cautions, warnings, and charging guidance as described above.

When displaying the charging message, the charging display control unit 119 displays the identified type in the charging message to be displayed.

FIG. 33 is a diagram showing processing in which a charging message is displayed by using the charging rate master DB 116 and the management table 117.

The line (1) in FIG. 33 shows a process performed when the amount of data acquired by the storage capacity acquisition unit 115 is 50 MB. In the case of (1), the acquired data amount of 50 MB is less than 100 MB × 80% = 80 MB multiplied by 80% with respect to 100 MB which is the minimum specific data amount. For this reason, the amount of data acquired is not near any specific data amount (100 MB, 500 MB, 1 GB, 2 GB). Therefore, the charge determination unit 118 determines that the acquired data amount of 50 MB is not the message data amount. By this determination being made, the charging display control unit 119 causes the charging message indicating that the data amount has reached the vicinity of the specific data amount to be displayed as shown in the rightmost column of the row (1). Instead, simply display the announcement "The current charge is 500 yen per month."

Rows (2) to (4) in FIG. 33 indicate processing performed when the amount of acquired data is 80 MB or more and less than 105 MB. In the case of (2) to (4), the amount of acquired data is equal to or greater than 80 MB and 100 MB × 105% = less than 105 MB. The amount of data in the vicinity of the specific data amount of 100 MB is determined to be the amount of message data. Since this determination is made, the charging display control unit 119 displays a charging message indicating that the data amount has reached the vicinity of the specific data amount. Then, in the cases of (2) to (4), the charging determination unit 118 determines that the data amount is included in the sections of caution, warning, and charging guide, respectively, and the type including the data amount. Is displayed in the charging message as a caution, warning, and charging guide.

That is, in the case (2) where the amount of data is 80 MB or more and less than 90 MB (= 100 MB × 90%), the charge determination unit 118 determines the type of the message as a warning, and the charge display control unit 119 displays the type to be careful. Further, in the case (3) where the amount of data is 90 MB or more and less than 104 MB (100 MB × 104%) (3), the charge determination unit 118 determines the type of the message as a warning, and the charge display control unit 119 Display a warning type. Also, if the data amount is 104 MB or more and less than 105 (100 MB × 105%) MB (4), the charge determination unit 118 determines the type of the message as the charge guide, and the charge display control The unit 119 displays the type of charging guide.

Similarly, when the acquired data amount is included in the vicinity of another specific data amount other than 100 MB, the charge determination unit 118 displays an appropriate display.

However, in cases (6) to (9), the amount of acquired data is near the amount of specific data, and the amount of specific data contained in the vicinity of the amount of data is the allowable amount of data (2 GB) Show the processing to be performed.

In the case of (6) to (9) in which the data amount has reached the vicinity of the allowable limit data amount, the charge display control unit 119, as shown in FIG. , Display a charging message indicating that the amount of data has reached the allowable amount of data.

Thus, the following mail function providing devices are configured.

In the web mail utilization system (in-house system 1), the web browser (web browser 200) of the computer (employee computer 12) displays a web mail interface (pages to be displayed, buttons, links, characters, etc.) Determining whether a webmail function providing unit (mail data acquisition unit 111) causing the user of the computer to use webmail and the transmission of the webmail performed by the web browser violate a predetermined rule Holding when the judgment unit (judgment unit 300), the word identification data storage unit (rule identification information DB 411) storing word identification data for identifying the word of the rule, and the judgment unit judges the violation Control unit that causes the web browser to display the specified term identification data Display control unit 421a: internal rule display control unit 421, accident case display control unit 422, avoidance method display control unit 423, confirmation processing unit 431, approval processing unit 432, determination log display control unit 502, charging display control unit 119) A mail function providing device (web mail server device 11) is provided. Here, to use web mail means to display the interface for editing the web mail on the computer, to obtain the mail data of the mail that has been edited, and by the destination computer of the mail destination, It means having the data stored in the destination mailbox so that the mail is received.

As a result, in the web browser using the mail function, the display of the wording of the rule for warning the user is performed. Thereby, regardless of the user's circumstances such as whether or not special software is installed on the user's computer, it is possible to reliably prevent inappropriate transmissions that violate the rules.

Moreover, not only a warning but also a persuasive basis for explaining that the transmission is inappropriate, the wording of the rule relating to the violation is displayed. This makes it possible to reliably, sufficiently and quickly raise the user's awareness that the transmission is inappropriate.

As a result, the function of e-mail is provided in the in-house system 1 in the company, and the user 12 u can reliably prevent inappropriate transmission despite the possibility of being a user who is low in consciousness to appropriately transmit. be able to. In addition, it is possible to make the user 12 u more aware of appropriate transmission easily and quickly. As a result, even if there is a low-conscious user, for example, a user who does not know the rule or a user who knows the rule late, it is possible to make each user use the mail function in the in-house system 1 in the company. .

That is, word-specific data (such as an Excel file) that can display a character string that is a word of a rule is stored by the word-specific data storage unit. On the other hand, determination of the rule is performed by the determination unit. When the violation is determined, the display control unit acquires, as data to be used for display, the wording specific data stored in the storage unit rather than the simple warning character string or the like. Wording specific data is used. Thus, the character string of the rule can be displayed at the time of display. As a result, more appropriate data can be displayed as data to be displayed when determining a violation.

The display control unit (violation processing unit 400) causes the in-company rule display control unit 421 to display the term identification data on the web browser.

In addition, when the web browser transmits a web mail, a data acquisition unit (mail data acquisition unit 111) that acquires data from the web browser, and the transmission has the data if the transmission violates the rule And a feature data holding unit (rule determination condition master DB 311) for holding feature data specifying a predetermined feature, wherein the determination unit is configured to specify the acquired data by the held feature data If it has a feature, a mail function providing device is configured to determine that the transmission is a violation. Here, the data acquisition unit is, for example, part or all of the mail function providing unit.

In addition, an accident case information storage unit (accident case information DB 412) for storing accident case information for specifying an accident case due to transmission violating the rule is provided, and the display control unit determines that the violation is determined. In addition, the mail function providing device is configured to cause the web browser to display the stored accident case information together with the wording specification data.

Thus, it is possible to prevent the user from being convinced why the rule is valid only by simply displaying the wording of the rule, and to avoid the situation where the violation of the rule is repeated. In other words, by showing the specific ground accident case that the rule is valid together with the rule, the user 12 u will be more likely not to violate, and there will be less inappropriate transmission more reliably. You can

The display control unit further includes an avoidance method information storage unit (a avoidance method information DB 413) for storing avoidance method information that specifies an avoidance method for avoiding the transmission from violating the rule, and the display control unit determines the violation. A mail function providing device is configured to display the stored avoidance method information on the web browser together with the wording specific data and the accident case information when being removed.

This prevents the user 12 u from being violated simply by not knowing the evasion method although the user 12 u intends to not violate the rules. That is, the avoidance method is known by displaying the avoidance method information on the web browser. This ensures that the user 12 u can avoid violations, and more reliably prevent inappropriate transmission and ensure proper transmission.

In addition, when the determination unit determines that the transmission is a violation, an avoidance method execution unit (a avoidance method display control unit 423) that executes a predetermined process of performing at least a part of the avoidance method. A mail function providing device provided is configured.

This allows the user 12 u to actually experience the transmission that avoided the violation immediately when the determination of the violation is made, and thereafter the user 12 u can use the avoidance method to avoid the violation. This can more reliably reduce the occurrence of inappropriate transmissions.

The display control unit (determination log DB 501) is configured to record recording data indicating that the determination is made when the determination unit determines that transmission is a violation. A display control unit 421a (judgment log display control unit 502) is a mail function that causes the web browser to display whether or not the judgment recording unit records the record when web mail is transmitted by the web browser. A provision device is configured.

In the mail function providing device, the display control unit displays the avoidance method information only when the recording data indicating that the determination recording unit determines that the violation is not made is recorded. Configured

In addition, the display control unit causes the interface to execute the predetermined process when the determination that the transmission is a violation is made (a page in the state shown in the right of FIG. 21, an execution button Ae1, etc. ) Is displayed on the web browser, and the avoidance method execution unit executes the processing when the user causes the processing to be input by the displayed interface when the determination of the violation is made. A mail function providing device is configured.

Further, the rule includes a first rule (rule of rule code R008) in which transmission of a web mail having a plurality of destinations is a violation, and the determination unit determines whether the destinations of the web mail to be transmitted are plural or not. When it is determined that there are a plurality of destinations, the display control unit displays the wording specific data of the first rule stored in the wording specific data storage unit on the web browser (for example, A mail function providing device for displaying the link RL (FIG. 7) is configured.

Thus, when a plurality of webmail destinations are sent, the second destination is revealed at the first destination. As a result, for example, there is a possibility that a rigging may occur between the first destination and the second destination. In other words, by revealing the other destination, which is information that is unnecessary to be clarified, an unexpected situation occurs. Processing is performed in the in-house system 1 for the first rule for avoiding such an unexpected situation.

In addition, such a rule that is hard to imagine for a low-conscious user is selected as a rule to be processed by the in-house system 1 so that information required for the user 12 u can be accurately displayed. .

Further, the avoidance method information storage unit stores the avoidance method information of the first rule, and the avoidance method information of the first rule to be stored is Blind Carbon Copy among the respective destination fields in the web mail. The method for describing the plurality of destinations in the field is shown, and the avoidance method execution unit corrects the web mail so that the plurality of destinations are described only in the Blind Carbon Copy field as the predetermined process. A mail function providing apparatus for performing processing is configured.

Here, the avoidance method information relating to the bcc column is the avoidance method information which is hard to imagine for a low-conscious user, and the necessary information can be accurately displayed.

The rule includes a second rule (rule of rule code R 007) violating the transmission if the transmission of the webmail is a transmission other than the transmission approved by the predetermined approver, Whether the avoidance method execution unit approves the transmission to the web browser of the approver's computer as the predetermined process when the determination unit determines that the second rule is violated. A mail function providing apparatus is configured to display an interface (approval availability notification (mail) 13M in FIG. 22) for transmitting a notification indicating “n” to the mail function providing apparatus.

Also, prior to the determination as to whether or not a violation has occurred, a notice indicating that the approver approves the transmission of the web mail is obtained in advance, and when the notice is obtained, recorded data indicating the obtaining. The mail function providing apparatus is configured to include an approval recording unit (approval history DB 314) that records the e-mail, and the determination unit does not determine that transmission violates the second rule when the recording data is recorded. Ru.

In addition, the determination unit determines whether the sender of the webmail is a predetermined excluded person (step S61 in FIG. 24), and only when it is determined that the sender is not the excluded person, A mail function providing apparatus is configured to determine that transmission violates the second rule.

In addition, when the approval recording unit is notified by the approver, the approval recording unit records the time of the notification, and the determination unit (determination unit 300) records the recording data by the approval recording unit.
