Description

The present invention relates to a terminal, a method, and a program.

As a measure against erroneous sending of electronic mail (hereinafter also referred to simply as "mail"), a technique is known in which a check screen is displayed to prompt the sender to confirm the legitimacy of the destination address and the legitimacy of the attached files before sending the mail, and the sender is made to check the check. For example, a technique is known in which a check screen is displayed to prompt the sender to confirm the legitimacy of the destination before sending the mail, and the mail is not sent until the confirmation results on the check screen are obtained (see, for example, Patent Document 1).

Japanese Patent Application Publication No. 2007-87327

However, with the above-mentioned conventional technology, the same check screen is displayed every time an email is sent, which can lead to senders sending emails without carefully checking the content. Furthermore, this can become a chronic problem, and the checks themselves can become a mere formality.

The present invention was made in consideration of the above points, and aims to prevent the erroneous sending of emails.

To achieve the above object, a terminal according to an embodiment of the present invention has a display control means for displaying at least one specific confirmation item, among the confirmation items included in a confirmation screen for preventing erroneous sending of a mail to be sent, among a confirmation item for confirming the body of the mail to be sent, a confirmation item for confirming an attachment of the mail to be sent, and a confirmation item for confirming the destination of the mail to be sent, in a more prominent display manner than the other confirmation items.

It is possible to prevent email from being sent incorrectly.

It is a figure showing an example of employee information. FIG. 3 is a diagram showing an example of erroneously sent email information. FIG. 2 is a diagram illustrating an example of the operation of the email erroneous transmission prevention system according to the present embodiment. FIG. 3 is a diagram (part 1) showing an example of a confirmation screen. FIG. 2 is a diagram showing an example of a confirmation screen (part 2). FIG. 3 is a diagram showing an example of a confirmation screen (part 3).

Hereinafter, an embodiment of the present invention (hereinafter also referred to as "this embodiment") will be described. In this embodiment, a confirmation screen (a screen for the sender to confirm the validity of the email content) is generated according to the content of the email to be sent, the attributes of the sender, information on past erroneously sent emails, etc. An e-mail erroneous transmission prevention system 1 that prevents erroneous e-mail transmission by displaying the information on the sender's terminal will be described.

<Overall composition>
First, the overall configuration of a system 1 for preventing erroneous e-mail transmission according to this embodiment will be described with reference to Fig. 1. Fig. 1 is a diagram showing an example of the overall configuration of a system 1 for preventing erroneous e-mail transmission according to this embodiment.

As shown in FIG. 1, the email erroneous transmission prevention system 1 according to the present embodiment includes an erroneous transmission prevention server 10, one or more email sending/receiving terminals 20, one or more management terminals 30, and a mail server 40. and is included. These servers and terminals are communicably connected via any communication network such as an in-house LAN (Local Area Network).

The erroneous transmission prevention server 10 receives email from the email sending/receiving terminal 20 and generates a confirmation screen based on the content of the email, the sender's attributes, information on past erroneously sent emails, etc. The erroneous transmission prevention server 10 then transmits the generated confirmation screen to the email sending/receiving terminal 20, causing the confirmation screen to be displayed.

The erroneous transmission prevention server 10 also checks (checks) the confirmation screen displayed on the mail sending/receiving terminal 20, and when the sender issues a transmission instruction, it sends (transfers) the mail from the mail sending/receiving terminal 20 to the mail server 40. The erroneous transmission prevention server 10 is realized by one or more computers.

The mail sending/receiving terminal 20 is a terminal used by a mail sender (user). The email sending/receiving terminal 20 creates and sends emails (including forwarding and replying to emails) in response to user operations. Further, the mail sending/receiving terminal 20 receives mail from the mail server 40. Note that the mail sending/receiving terminal 20 is realized by, for example, a PC (personal computer). However, the email sending/receiving terminal 20 may be realized by various devices or devices such as a smartphone or a tablet terminal.

In this embodiment, the sender is assumed to be a member of a company, organization, etc. (e.g., an employee of a company, a staff member of an organization, a student of a school, etc.). Hereinafter, members of these companies, organizations, etc. will be collectively referred to simply as "employees."

The management terminal 30 is a terminal used, for example, by the administrator of the erroneous transmission prevention server 10. The management terminal 30 can operate (add, delete, edit) information stored in the template screen generation rule storage unit 111, the employee information storage unit 112, the erroneous transmission email information storage unit 113, etc., described below, in response to operations by the administrator.

The mail server 40 forwards the mail from the erroneous transmission prevention server 10 to another device according to the destination address. Furthermore, the mail server 40 forwards mail from other devices to the mail sending/receiving terminal 20 or the like according to the destination address. In addition, in this embodiment, when simply written as "destination address", it means the email address set in the To field of the email, the email address set in the Cc field, and the email address set in the Bcc field. This refers to all of the above.

Here, the erroneous transmission prevention server 10 has, as its functional units, a transmission control unit 101 and a screen generation unit 102. Each of these functional units is realized, for example, by a process in which one or more programs installed in the erroneous transmission prevention server 10 are executed by a CPU (Central Processing Unit) or the like.

The erroneous transmission prevention server 10 also has, as storage units, a template screen generation rule storage unit 111, an employee information storage unit 112, and an erroneously transmitted email information storage unit 113. Each of these storage units can be realized using, for example, a hard disk drive (HDD) or a solid state drive (SSD). However, at least one of these storage units may be realized using a storage device or the like that is connected to the erroneous transmission prevention server 10 via a communication network.

The transmission control unit 101 receives mail (hereinafter also referred to as "mail to be sent") from the mail sending/receiving terminal 20, and controls the sending of the mail to be sent. When confirmation is made on the confirmation screen and a transmission instruction is given by the sender (or when the confirmation screen is not displayed on the mail sending/receiving terminal 20), the transmission control unit 101 sends (transfers) the mail to be sent received from the mail sending/receiving terminal 20 to the mail server 40.

The screen generation unit 102 generates a confirmation screen according to the contents of the target email received from the email sending/receiving terminal 20, the sender's attributes, information on past erroneously sent emails, and the like. Then, the screen generation unit 102 transmits the generated confirmation screen to the email sending/receiving terminal 20.

Here, the screen generation unit 102 generates a confirmation screen template based on, for example, the contents of the email to be sent and the template screen generation rules stored in the template screen generation rule storage unit 111. Then, the screen generation unit 102 generates a confirmation screen by editing the confirmation screen template (hereinafter also referred to as the "template screen") using the employee information stored in the employee information storage unit 112, the erroneously sent email information stored in the erroneously sent email information storage unit 113, and the trained machine learning model.

Note that the trained machine learning model is a model in which trends in content to be displayed as a confirmation screen have been learned in advance using employee information indicating employee attributes and past erroneously sent email information. As the machine learning model, any model used in machine learning methods is used. Further, such a machine learning model may be available using a library, an API (Application Programming Interface), a Web API, or the like.

The template screen generation rule storage unit 111 stores template screen generation rules, which are a rule table for generating template screens. Details of the template screen generation rules will be described later.

The employee information storage unit 112 stores employee information indicating the attributes of the employee (sender). Details of employee information will be described later.

The erroneously sent email information storage unit 113 stores erroneously sent email information that indicates information about emails that have been erroneously sent in the past. Details of the erroneously sent email information will be described later.

As described above, the template screen generation rules, employee information, and erroneously sent email information can be created and edited by the administrator using the management terminal 30. However, the erroneously sent email information may be automatically collected in the erroneously sent email information storage unit 113, for example, every time an erroneous email is sent (or periodically).

Furthermore, the mail sending/receiving terminal 20 has, as functional units, a mail processing unit 201 and a display control unit 202. Each of these functional units is realized, for example, by a process executed by a CPU or the like of one or more programs (e.g., a mail application, etc.) installed in the mail sending/receiving terminal 20.

The email processing unit 201 performs processing related to the creation and sending of emails (including forwarding and replying). The display control unit 202 displays the confirmation screen received from the erroneous transmission prevention server 10.

Note that the configuration of the email erroneous transmission prevention system 1 shown in FIG. 1 is an example, and other configurations may be used. For example, the email erroneous transmission prevention system 1 may not include the management terminal 30. Further, for example, some functional units (for example, the screen generation unit 102) of the erroneous transmission prevention server 10 may be realized by a device or system (for example, a cloud server, etc.) connected via a communication network.

<Stemplate screen generation rules>
Here, the template screen generation rules stored in the template screen generation rule storage unit 111 will be explained with reference to FIG. 2. FIG. 2 is a diagram showing an example of template screen generation rules.

As shown in FIG. 2, the template screen generation rule storage unit 111 stores template screen generation rules consisting of one or more records. Each record includes the following fields: "record number," "email attributes," "destination address," "add address," "attachment," "keywords," and "template screen."

Among these fields, "email attributes", "destination address", "address addition", "attachment", and "keyword" are the conditions, and when these conditions are met, the "template screen" corresponding to the condition is displayed. " is generated. The template screen generation rule stores the number of records corresponding to the combinations of values that each of these conditions can take. That is, each record is information that associates conditions for generating a template screen with the template screen.

In "Record No.", identification information that uniquely identifies each record is set. In "Email Attribute", one of the following conditions is set: "New", which indicates that the email is a newly created and sent email, "Reply", which indicates that the email is a reply to a previously received email, or "Forward", which indicates that the email is a forwarded received email.

For "Destination address", either "Internal only" indicating that the destination address is an address within the company only, or "Includes outside the company" indicating that the destination address includes an address outside the company is set as a condition. Ru. Note that, for example, "contains a specific address" indicating that a predetermined specific address is included in the destination address may be set as a condition.

"Whether or not an address is added" is based on whether or not an email address has been added to the received email that was the target of reply or forwarding when the "email attribute" is "reply" or "forward". Set. In addition, if "Added" is set to indicate that an email address has been added to a received email, "Added" is set to indicate that the added email address is only an internal email address. The conditions may be further subdivided into "with addition (external)" indicating that the email address includes an external email address. In addition, when the above-mentioned specific address is added, it may be subdivided into "added (specific address)", for example.

In the "attachment presence/absence" field, whether or not a file is attached to the email is set as a condition. Note that when "Yes" is set indicating that a file is attached to the email to be sent, the conditions may be further subdivided to include information indicating the type of attached file. For example, if a PDF file is attached, it may be subdivided into "Yes (PDF)", when an executable file is attached, it may be subdivided into "Yes (EXE)", etc.

In "Keyword," the condition is set as whether the email contains a string that matches or partially matches a specified keyword. For example, if it is set as "Matches 'Estimate'," the condition is that the email contains the string "Estimate."

Note that various judgment statements may be set in the "keyword". For example, if the "∨" operator, which indicates "or", is used to set "match, 'A∨B'", the condition is that the email contains either the character string "A" or "B". Similarly, the "∧" operator, which indicates "and", may be used.

In addition, the "keyword" may be set to a location in the email that contains a specific keyword (e.g., the subject, the body, the attachment file name, etc.). For example, if it is set to "match, attachment file name, 'A ∨ B'", the condition is that the attachment file name contains either the character string "A" or "B".

In the "template screen", information regarding a template screen that is generated when each of the above conditions is satisfied is set. The "template screen" further includes "display presence/absence" indicating whether or not to display the template screen, and "items" included in the template screen when displaying the template screen. Here, the item refers to a confirmation item.

Examples of such "items" include "body," "attachment," "destination," and "warning." For example, if "body" is set as the "item," the confirmation screen displays a message indicating that the email body should be checked. Similarly, if "attachment" is set as the "item," the confirmation screen displays a message indicating that the attachment should be checked. Similarly, if "destination" is set as the "item," the confirmation screen displays a message indicating that the destination (recipient email address) should be checked. On the other hand, if "warning" is set as the "item," the confirmation screen displays a message indicating that the email contains a character string that matches the above "keyword" condition as a warning to the sender.

In this way, the template screen generation rules store one or more records that correspond to each condition and the template screen that is generated when each condition is met. This allows a template screen that serves as a confirmation screen template to be generated depending on the email to be sent.

<Employee Information>
Next, the employee information stored in the employee information storage unit 112 will be described with reference to Fig. 3. Fig. 3 is a diagram showing an example of employee information.

As shown in FIG. 3, the employee information storage unit 112 stores one or more pieces of employee information. Each of these employee information includes employee attribute information such as ``name,'' ``department,'' ``position,'' ``years of service,'' ``email address,'' ``risk,'' and ``number of incorrect transmissions.'' ” is included.

"Name", "Department", "Position", "Years of Service", and "Email Address" are set with the employee's name, department, position, years of service, and email address, respectively.

Risks are set according to the employee's department, position, years of service, past rule violations, etc. For example, if there are many sales emails addressed to outside the company, "sales mail" is set, and if there has been a violation of internal rules in the past, "company rules violated" are set as risks.

The "Number of times erroneously sent" field is set to the number of times erroneously sent emails have been sent in the past. The reason for the erroneous sending of the email (e.g., "wrong destination" or "wrong attachment") and the number of times it was sent may also be set.

In this way, employee information includes various attribute information of employees. This makes it possible, for example, to use a machine learning model to determine items that should be specifically confirmed according to the attributes of the sender (employee). become. Note that, for example, the template screen may be edited so as to include the determined item.

<Incorrectly sent email information>
Next, the erroneously sent email information stored in the erroneously sent email information storage section 113 will be explained with reference to FIG. 4. FIG. 4 is a diagram illustrating an example of erroneously sent email information.

As shown in FIG. 4, the erroneously sent email information storage unit 113 stores one or more pieces of erroneously sent email information. These erroneously sent email information is information about erroneously sent emails that occurred in the past, and includes "To", "Cc", "Bcc", "Subject", and " ``body'', ``presence of attachment'', and ``reason for error'' are included.

"To", "Cc", "Bcc", "Subject", "Body" and "Attachment" are set to the email address set in the To field of the erroneously sent email, the email address set in the Cc field, the email address set in the Bcc field, the subject, the body and whether or not there is an attachment.

The reason why the erroneously sent e-mail occurred is set in the "error reason" field. Examples of such reasons include "wrong destination" and "wrong attached file."

In this way, the erroneously sent email information includes the contents of erroneously sent emails that occurred in the past, the reason for the error (the reason for the occurrence), and the like. This makes it possible, for example, to use a machine learning model to determine items that should be specifically checked depending on the content of the email to be sent. Note that, for example, the template screen may be edited so as to include the determined item.

However, the mis-sent email information storage unit 113 does not have to store all of the mis-sent email information that has occurred in the past. For example, the mis-sent email information storage unit 113 may store only mis-sent email information related to mis-sent emails that have occurred recently, or may store only mis-sent email information related to the most recent mis-sent email. Or, for example, the mis-sent email information storage unit 113 may store only mis-sent email information related to mis-sent emails selected by an administrator, etc.

<Operation of erroneous e-mail sending prevention system 1>
Next, the operation of the process for preventing erroneous e-mail transmission by the erroneous e-mail transmission prevention system 1 according to the present embodiment will be described with reference to FIG. FIG. 5 is a diagram illustrating an example of the operation of the erroneous mail transmission prevention system according to the present embodiment. In the following, it is assumed that a sender performs a mail sending operation (an operation for sending a new mail, an operation for replying to or forwarding a received mail) using the mail sending/receiving terminal 20.

The email processing unit 201 of the email sending/receiving terminal 20 accepts an email sending operation by the sender (step S101).

When the email processing unit 201 of the email sending/receiving terminal 20 receives the email sending operation, it sends the email to be sent to the erroneous sending prevention server 10 (step S102).

The transmission control unit 101 of the erroneous transmission prevention server 10 receives the email to be sent (step S103).

Next, the screen generation unit 102 of the erroneous transmission prevention server 10 refers to the template screen generation rules stored in the template screen generation rule storage unit 111, identifies a record for which the target email satisfies the conditions, and generates a template screen associated with the conditions in the identified record (step S104).

More specifically, the screen generation unit 102 identifies records that satisfy the conditions among the records that constitute the template screen generation rules, based on the email attributes of the email to be sent, the destination address, whether an address has been added, whether an attachment has been added, whether a keyword is included, etc. Then, if "displayed" is set for the "template screen" included in the identified record, the screen generation unit 102 generates a template screen that includes the items set in each "item" of the "template item."

Here, if the "display presence/absence" of the "template screen" included in the identified record is set to "no display", the screen generation unit 102 does not generate the template screen. In this case, steps S105 to S109, which will be described later, are not executed, and the mail to be sent is sent in step S110, which will be described later. This is because in this case, confirmation of the sender is not required.

Although the template screen is generated in step S104 above, it does not necessarily need to be generated, and it is sufficient to simply specify the items included in the template screen.

Next, the screen generation unit 102 of the erroneous transmission prevention server 10 generates the employee information stored in the employee information storage unit 112 (or the employee information and the erroneously sent email stored in the erroneously sent email information storage unit 113). information) to edit the template screen and generate a confirmation screen (step S105).

More specifically, the screen generation unit 102 first identifies the employee information of the sender from the sender address of the email to be sent (i.e., the sender's email address). Next, the screen generation unit 102 inputs the identified employee information (or both the identified employee information and the erroneously sent email information stored in the erroneously sent email information storage unit 113) into a machine learning model to obtain items (confirmation items) according to the sender's attributes and the content of the email to be sent. Note that the content of the email to be sent may also be input into the machine learning model.

Then, the screen generation unit 102 generates a confirmation screen by editing the template screen using the obtained items.

At this time, the screen generation unit 102 may, for example, generate a confirmation screen that includes only common items between the obtained items and the items included in the template screen, or may generate a confirmation screen that includes only the obtained items. A screen may be generated, or a confirmation screen may be generated by adding the obtained items to the template screen. Alternatively, the screen generation unit 102 may, for example, ensure that the total number of the obtained items and the items included in the template screen is equal to or less than a predetermined number, and that the obtained items are the items included in the template screen. A confirmation screen may be generated that is preferentially included.

Note that the machine learning model used is one that has been trained in advance so that items to be confirmed by the sender are output according to the sender's attributes and the contents of the email to be sent.

Next, the screen generation unit 102 of the erroneous transmission prevention server 10 transmits the confirmation screen generated in step S106 above to the email sending/receiving terminal 20 (step S106).

The display control unit 202 of the email sending/receiving terminal 20 displays the confirmation screen received from the erroneous transmission prevention server 10 (step S107). An example of the confirmation screen displayed by the display control unit 202 is shown in Figs. 6 to 8. Figs. 6 to 8 are diagrams showing an example of the confirmation screen.

The confirmation screen 1100 shown in FIG. 6 includes a subject confirmation item 1101, a destination (To) confirmation item 1102, a destination (Cc and Bcc) confirmation item 1103, a text confirmation item 1104, and an attached file as items (confirmation items). Confirmation item 1105 and warning confirmation item 1106 are included. The sender can perform a transmission instruction operation by pressing the send button 1107 after confirming the validity of the mail to be sent using each of these confirmation items, and can send the mail to be sent.

Unlike the confirmation screen 1100 shown in FIG. 6, the confirmation screen 1200 shown in FIG. 7 includes only a subject confirmation item 1101 and a text confirmation item 1104. That is, confirmation screen 1200 shown in FIG. 7 has fewer confirmation items than confirmation screen 1100 shown in FIG. 6. In this way, for example, by displaying only the items that the sender particularly wants to confirm, it is possible to prevent the sender from chronically checking the information.

The confirmation screen 1300 shown in FIG. 8 differs from the confirmation screen 1100 shown in FIG. 6 in that it only includes an attachment confirmation item 1105 and a warning confirmation item 1106. This is similar to FIG. 7 in that, for example, only the items that the sender is specifically required to confirm are displayed, and this can prevent the sender from becoming chronically hesitant to confirm.

In this way, in the email erroneous transmission prevention system 1 according to the present embodiment, the confirmation items on the confirmation screen displayed on the email sending/receiving terminal 20 of the sender are changed depending on the attributes of the sender and the contents of the email to be sent. be done. This makes it possible to prevent sender confirmation from becoming a chronic problem and prevent erroneous email transmission, as well as to reduce the burden of confirmation.

Note that in this embodiment, only the confirmation items are changed, but in addition to this, for example, the design of the confirmation screen (for example, the background color of the confirmation screen, the arrangement of confirmation items, etc.) may be changed. Further, in this embodiment, a confirmation screen that includes only the confirmation items that the sender particularly wants to confirm is displayed, but the present invention is not limited to this. For example, a confirmation screen that includes all confirmation items may be displayed to Only the confirmation items that are particularly desired to be confirmed may be displayed in a conspicuous manner. The conspicuous display mode may be, for example, displaying only the relevant confirmation item in a large size (for example, displaying it twice or three times larger than a normal confirmation item). Alternatively, as a conspicuous feature, for example, a certain character string (for example, an e-mail address set as a destination) in the corresponding confirmation item may be changed in color or blinked. Furthermore, in the case of confirmation items for confirming recipients (To) and recipients (Cc and Bcc), for example, instead of displaying all recipients, only external email addresses may be displayed, or additional items may be added. You can display only the e-mail address that has been entered, or you can display the size of a certain part of the character string in the e-mail address (for example, the character string before the @ or the character string after the @). The display mode may be changed by changing the display mode or changing the color.

The display mode may be different depending on a certain time period or the time period before or after a certain schedule. For example, during times when the risk of erroneous transmission is high (e.g., before work, late at night, before a business trip, just before a meeting, etc.), the message may be displayed in a particularly noticeable manner. The schedule may be specified in advance, or may be different for each user based on a personal schedule book, etc.

Furthermore, for example, a "risk" item may be set in the template screen generation rule (for example, this item may be set to "includes attachments" or "includes external addresses", or a value that quantifies risk) and each record of the template screen generation rule may be ranked according to this risk. For example, "includes attachments" may be given the "first" risk rank, "includes external addresses" the "second" risk rank, "contains a specified keyword in the text" the "third" risk rank, etc. Then, the confirmation items in the confirmation screen may be displayed from the top according to the risk rank, or the confirmation items may be displayed in a display mode according to the risk rank (for example, the higher the risk rank, the larger the display).

Following step S107, the email processing unit 201 of the email sending/receiving terminal 20 accepts the sending instruction operation on the confirmation screen (step S108).

When the email processing unit 201 of the email sending/receiving terminal 20 receives the sending instruction operation, it sends the sending instruction to the erroneous sending prevention server 10 (step S109).

When the transmission control unit 101 of the erroneous transmission prevention server 10 receives the transmission instruction, it transmits the email to be sent to the mail server 40 (step S110). As a result, the mail server 40 transmits the email to be sent to the destination address.

<Summary>
As described above, in the email erroneous transmission prevention system 1 according to the present embodiment, the trained machine learning model is used to check the contents of the email to be sent, the sender's attributes, past erroneously sent email information, etc. Change the confirmation items included in the screen. This makes it possible for the sender to appropriately confirm the items to be confirmed, making it possible to effectively prevent erroneous email transmission. Furthermore, since the number of items that the sender must check is reduced compared to the case where all items are checked uniformly, it is possible to reduce the burden of confirmation on the sender.

In this embodiment, a template screen determined by the conditions satisfied by the email to be sent is generated or identified, and then the confirmation screen is generated by editing this template screen, but this is not necessarily limited to this. For example, a confirmation screen may be generated using a trained machine learning model in accordance with the content of the email to be sent, attribute information of the sender, information on past erroneous emails, etc., without generating or identifying a template screen.

The present invention is not limited to the above-described specifically disclosed embodiments, and various modifications and changes can be made without departing from the scope of the claims.
