Description

  The present invention relates to a technique for preventing erroneous transmission of an email, which enables an erroneous transmission due to an artificial error such as an error in an electronic mail address of a partner and an attachment file to be forgotten to be confirmed when the electronic mail is transmitted.

  When using an e-mail system, there is a problem that if the wrong party is mistaken, the other party to whom an unrelated mail is sent will not only be inconvenienced, but the contents that require confidentiality will be known to others. is there. There is also a problem in that if an attachment is forgotten or the content is incorrect, it is necessary to send the mail again and ask the other party to delete the previous mail. Therefore, various proposals have been made for preventing erroneous mail transmission that causes these problems (for example, Patent Document 1).

Patent Document 1 discloses a method for easily and surely confirming erroneous transmission of an electronic mail. In Patent Document 1, the server temporarily holds the email sent by the sender, and before the server delivers the email to the recipient, the email sent by the sender is delivered to the sender. A method to confirm the contents is proposed.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings. This is merely an example, and the technical scope of the present invention is not limited to this.

[Functional configuration of an erroneous email transmission prevention device equipped with an erroneous email prevention program]
FIG. 1 is a diagram illustrating a functional configuration of an erroneous email transmission prevention apparatus 1 including an erroneous transmission prevention program according to the present embodiment. The erroneous mail transmission prevention device 1 includes an input unit 3, an email management unit 10, and an erroneous transmission prevention unit 20. The mail management means 10 is a function that is generally provided by application software called a mailer, and is, for example, Outlook Express or Netscape Messenger. The mail management means 10 has various functions. Here, the mail management means 10 includes a mail creation means 11, a mail control means 12, a mail display means 13, and a mail transmission / reception means 14, which are necessary in the following description.

  The erroneous transmission prevention means 20 is one of the functions provided by the program of the erroneous transmission prevention method according to the present invention. The erroneous transmission prevention means 20 includes a mail determination means (transmission determination means) 21, an input content editing means (information acquisition means) 22, a confirmation mail creation means 23, an encryption means 24, an address DB (address storage means) 30, and a domain. A DB (domain storage means) 31 is included. In addition, it is good also as a system which uses each means and each DB as an external device, and connects these external devices in a communication network. Further, the mail management unit 10 may include the erroneous transmission prevention unit 20. In the present embodiment, the mail display means 13 and the confirmation mail creation means 23 are used as the presenting means. The presenting means presents the contents using the confirmation mail created by the confirmation mail creating means 23 to a person who confirms whether there is an error in the contents of the transmission e-mail (hereinafter referred to as a confirmer).

  The mail creating means 11 creates a scheduled mail for transmission based on the contents input by the user of the erroneous mail transmission preventing apparatus 1 using the input means 3. The emails to be sent are both newly created emails (hereinafter “email” is simply called email for brevity) and emails that have been created again by modifying the email that has already been created. including. In addition, the mail creation means 11 provides other functions used when creating a mail, for example, functions such as attaching a file to a mail, storing a mail, and printing a mail.

  The mail control unit 12 accepts a transmission instruction input by the user of the erroneous mail transmission preventing apparatus 1 through the input unit 3 with respect to the transmission planned mail or the transmission mail, and passes the transmission planned mail or the transmission mail to the mail determination unit 21. Here, the transmitted mail is a confirmation mail created for the planned mail to be sent, and it is confirmed by the confirmer that there is no error in the planned mail to be sent. Therefore, it is a planned mail to be transmitted to the other party.

  The mail display means 13 displays received mail and outgoing mail as a list on an output means (not shown), and individually displays the contents of the mail on an output means (not shown). The mail transmission / reception means 14 transmits a mail to a mail partner via the network, and an electronic mail address (hereinafter referred to as an address for brevity) owned by the user of the erroneous mail transmission preventing apparatus 1 is the partner. Receiving e-mail.

  The mail determination means 21 determines whether or not the mail delivered from the mail control means 12 is a transmission mail to be transmitted by the mail transmission / reception means 14. In other words, the mail determination means 21 determines whether or not it is a transmission planned mail for which a confirmation mail is to be created. When the mail determination means 21 determines that the mail delivered from the mail control means 12 is a planned transmission mail, the mail determination means 21 passes the planned transmission mail to the input content editing means 22. On the other hand, when the mail determination means 21 determines that the mail delivered from the mail control means 12 is a transmission mail, the mail determination means 21 passes the transmission mail to the mail transmission / reception means 14.

  The input content editing means 22 changes the description format of the property of the scheduled mail to be transmitted so that the confirmer can easily confirm it visually. The properties of the scheduled mail are the destination and the transmission date / time. The confirmation mail creating means 23 creates a confirmation mail in which the properties of the mail whose format has been converted by the input content editing means 22 are described in the mail text. The encryption unit 24 performs encryption on the transmitted mail passed to the mail transmission / reception unit 14.

  The address DB 30 stores a plurality of addresses designated as counterparts, a plurality of names possessing each address, and a plurality of pieces of encrypted information for encrypting mail in association with each other. The domain DB 31 stores a plurality of domains included in each address designated as a destination and a plurality of organization names that own the domains in association with each other.

[Address DB]
FIG. 2 is a diagram showing an address table of the address DB 30. As shown in FIG. The address table includes items such as an address column 40, a name column 41, an encryption flag column 42, and an encryption information column 43. The address table may not include the encryption flag column 42 as long as it includes at least the address column 40, the name column 41, and the encryption information column 43. The address table may include other items, for example, image information such as company marks. Furthermore, as long as the address table includes an address, a name, and encryption information, an address book provided in the mailer may be used.

  The address field 40 stores the address of the other party specified by TO, CC, and BCC in the mail. The address may be a personal address or a group address. In the name column 41, names of personal users who are users of the address and departments of the company are stored. The name column 41 may store the company name, the school name, and the like.

  The encryption flag column 42 stores information on whether or not to encrypt mail. For example, as shown in FIG. 2, it is possible to indicate whether or not the encryption flag is encrypted with a flag of 0 and 1. Here, “0” indicates that encryption is required, and “1” indicates that encryption is not required. The encryption information column 43 is information for encrypting plain text mail, and includes, for example, a password, a public key method, and a common key method. In FIG. 2, the address “aaa@xxx.co.jp” is an address owned by “XX Company Taro Tanaka”, and the mail is sent using the encryption information specified in the encryption information item. Stores encrypted transmission.

[Domain DB]
FIG. 3 is a diagram showing a domain table of the domain DB 31. As shown in FIG. The domain table includes items such as a domain column 44 and an organization name column 45. Note that the domain table only needs to include at least the domain column 44 and the organization name column 45, and may include other items.

  The domain column 44 stores identifiers assigned to computers and networks existing on the Internet. In the organization name column 45, an organization name represented by a domain, for example, a company name or a school name is recorded. The domain has a hierarchical structure like a real-world address, and the top level domain (TLD: Top Level Domain), second level domain (SLD: Second Domain), and third It is aligned with the level domain (LD: Second Level Domain).

  The top level domain or the like means an organization name, and the closer to the top level domain, the larger the organization. That is, each domain delimited by “.” Belongs to the right domain, for example, the second level domain belongs to the top level domain. Therefore, by registering not only the domain but also the top-level domain or the like individually in the domain DB 31, it is possible to specify a rough organization to which the domain belongs even for a domain that is not registered.

  For example, the domain “xxx.co.jp” at the address “aaa@xxx.co.jp” indicates that “Ox company” is owned by FIG. Further, since the domain “xxx.co.us” at the address “ccc@xxx.co.us” is not registered in the domain table shown in FIG. 3, each domain “xxx”, “ “co” and “us”. As a result of the search, “co” is “company”, and “us” is “US”, so that “xxx.co.us” is “US company”.

  It is also effective to search for a domain including “xxx”. In the example described above, if the domain is “xxx.co.us”, “xxx.co.jp” is searched as a domain including the same “xxx”. "Xxx.co.us" is supposed to have some relationship with "xxx company" that owns "xxx.co.jp", and combined with the above results, "XX company in America" is displayed. Thus, the organization name can be estimated and displayed for any domain that is not registered in the domain DB 31.

[Incorrect transmission prevention processing]
FIG. 4 is a flowchart of erroneous transmission prevention processing. FIG. 5 shows a schematic diagram of a scheduled mail. Based on the contents input by the user of the erroneous mail transmission preventing apparatus 1 using the input means 3, the mail creating means 11 creates a scheduled mail and presses the send button 50 shown in FIG. Is received, the e-mail to be sent is passed to the e-mail determination means 21, and the process starts.

  When creating a mail, a mail creating means 11 which is a function provided by application software called a mailer is used. As shown in FIG. 5, the mail creation screen includes a send button 50, a file insertion button 51, a TO field 52, a CC (Carbon Copy) field 53, a BCC (Blind Carbon Copy) field 54, an attachment field 55, a subject field 56, And a text column 57 and the like. Here, a specific mail creation process of the user of the erroneous mail transmission preventing apparatus 1 will be described, and will be described as a process in the mail shown in FIG.

  The user of the erroneous mail transmission preventing apparatus 1 sets the mail address “aaa@xxx.co.jp” in the TO field 52, the mail subject “announcement of regular meeting” in the subject field 56, and the mail text “○ “Oh ...” is entered in the text field 57. If there is an attached file, the user can attach the file to the mail by clicking the file insertion button 51 and specifying the file on the pop-up screen (not shown). In FIG. 5, “Meeting material.txt” is attached. The attached file name is displayed in the attachment field 55. Here, the attached file is a file such as a text, an image, and a sound that is sent along with the body of the mail.

  Further, when mail is to be transferred to a destination other than the address specified in the TO column 52, the address of the destination to which the email is to be transferred is input to the CC column 53 and the BCC column 54. In FIG. 5, “bbb@xxx.co.jp” is stored in the CC column 53, “ccc@yyy.co.jp”, “dddd@mmm.co.jp”, and “ “eeee@ppp.co.jp” is input. When all necessary items have been entered, when the user of the erroneous mail transmission preventing apparatus 1 presses the transmission button 50, the mail control means 12 accepts the transmission, and the mail to be sent is sent to the mail determination means 21. In the above description, the user of the erroneous mail transmission preventing apparatus 1 transmits the mail created by the user, but the user does not need to transmit the mail created by the user. You may send an email created by. Therefore, the user who created the mail does not always match the user who sent the mail.

S1: The mail determination means 21 determines whether or not to create a confirmation mail for the scheduled mail sent from the mail control means 12. A method of determining whether to create a confirmation mail will be described later.
S2: In step S1, when the mail determination means 21 determines to create a confirmation mail, the input content editing means 22 and the confirmation mail creation means 23 create a confirmation mail.

[Confirmation email creation process]
FIG. 6 is a flowchart of confirmation mail creation processing. The confirmation mail creation process will be described with reference to FIG.
S11: The input content editing means 22 uses the address DB 30 to name and encrypt based on the addresses input in the TO column 52, CC column 53, and BCC column 54 in the schematic diagram of the planned outgoing mail shown in FIG. Get the flag. Name acquisition will be described by taking the address “aaa@xxx.co.jp” in the TO column 52 in the scheduled transmission mail shown in FIG. Here, assuming that the address DB 30 shown in FIG. 2 is used, the input content editing means 22 searches the address DB 30 on the condition of “aaa@xxx.co.jp” in the address DB 30, and the name “XX Company Taro Tanaka” Is obtained.

  S12: The input content editing means 22 determines whether or not a name has been acquired in step S11.

  S13: If the input content editing unit 22 determines in step S12 that the name could not be acquired, the input content editing unit 22 acquires the organization name from the domain DB 31 based on the domain included in the address. The acquisition of the organization name will be described by taking “aaa@xxx.co.jp” specified in the TO column 52 as an example in the schematic diagram of the scheduled transmission mail shown in FIG. Here, assuming that the domain DB 31 shown in FIG. 3 is used, the input content editing means 22 searches the domain DB 31 using the domain “xxx.co.jp” below @ as a condition, and acquires the organization name “XX company”. To do.

  If the domain “xxx.co.jp” below @ is not stored in the domain DB 31, the input content editing means 22 is a domain for each block obtained by dividing the domain below @ by “.”, That is, the top level. -The domain DB 31 is searched using each domain as a search term. In the above example, the search terms are “xxx”, “co”, and “jp”. This makes it possible to specify a rough organization name to which the domain belongs even for a domain that is not registered. It is also possible to infer an organization from domains including the same top level domain. Even when the name is acquired in step S11, step S13 may be performed to acquire both the name and the organization name.

  S14: The input content editing means 22 converts the notation of the time when the send button 50 shown in FIG. 5 is pressed into a notation format that can be easily confirmed by the checker of the confirmation mail. The notation format includes a format that separates numbers that represent the date with ":", "/", or "date", and a format that separates numbers that represent time with ":" or "hours and minutes". is there. Moreover, you may convert a number into a full-width or a Chinese number.

S15: The input content editing means 22 determines whether or not there is an attached file in the transmission scheduled mail.
S16: If it is determined in step S15 that there is an attached file, the input content editing unit 22 acquires the property of the attached file for each attached file. The attached file properties include the file size, creation date, update date, presence / absence of encryption, and the like. For obtaining the property of the attached file, an existing technique is used, for example, a technique for obtaining the property of the attached file provided by an OS (Operating System) such as Windows (registered trademark).

  S17: The confirmation mail creating means 23 creates a confirmation mail using the information acquired in steps S11 to S16 and the planned transmission mail. FIG. 7 is a diagram illustrating an example of presenting the contents of a planned email to be transmitted by a confirmation email. The confirmation mail corresponds to the transmission planned mail shown in FIG. Specific methods for presenting the contents of the e-mail to be sent to the confirmer include a method of describing the contents in the confirmation mail body and presenting it to the confirmer, or dividing the contents into several parts, one by one. There is a method of presenting in a popup with a confirmation button. FIG. 7A is a diagram showing an example of presentation when the content of the planned email to be sent is written in the text field 77 of the confirmation email. FIG. 7B is a diagram showing an example of presentation when a program for confirming the contents of a scheduled mail to be sent one by one in a pop-up is attached to the confirmation mail. With reference to the presentation example of FIG. 7A, the content of the transmission planned mail to be presented will be described below. The content presented in FIG. 7A is the same as in FIG. 7B.

  In the TO column 72, the address of a person who confirms the content of the scheduled transmission mail, for example, the user of the erroneous mail transmission preventing apparatus 1 that has transmitted the planned transmission mail is specified. In FIG. 7, nothing is specified in the CC column 73 and the BCC column 74, but an address such as a mail manager or a person in the same department may be specified. Thereby, a double check can be performed and erroneous transmission can be more effectively prevented. Further, in the TO column 72, an address of a mail manager or a person in the same department may be designated instead of the address of the user of the erroneous mail transmission preventing apparatus 1 that has transmitted the scheduled mail. As a result, the e-mail to be sent will be sent after confirmation by the e-mail administrator, etc. Therefore, not only double check to prevent wrong e-mail transmission but also approval to send e-mail must be obtained You can add a mechanism. As described above, not only the user of the erroneous mail transmission preventing apparatus 1 that has transmitted the planned outgoing mail but also a mail manager or the like may be designated as the confirmer.

  In the subject field 76, the same subject as that of the scheduled mail is specified. As a result, the user of the erroneous mail transmission preventing apparatus 1 that has transmitted the scheduled mail can easily grasp which mail corresponds to the confirmation mail. In order to clarify that it is a confirmation mail, a word that can be seen at a glance such as “confirmation mail” or “confirmation required” may be added to the subject of the transmission mail.

  In the text column 77, in FIG. 5, the number of addresses specified in the TO column 72, CC column 73, and BCC column 74, confirmation items for each address, mail transmission date and time, and when there is an attached file in the mail Indicates the properties of the attached file and the mail text. As described above, since all items to be confirmed are described in the text column 77 to prevent erroneous transmission of the e-mail, the confirmer only needs to confirm the text column 77. Moreover, since the confirmation part is only the text column 77, it is possible to prevent the confirmation person from omission of confirmation. Hereinafter, the contents described in the text column 77 will be described in detail.

  First, the confirmation mail describes how many destination addresses specified in the TO column 52, CC column 53, and BCC column 54 of the planned transmission email shown in FIG. Is done. In FIG. 5, it is displayed that there are five destinations because one item is specified in the TO column 52, one item in the CC column 53, and three items in the BCC column 54. By describing the number of addresses of the other party, the confirmer can easily find the presence or absence of address specification omission by looking at the number of addresses.

  Secondly, confirmation items for each address are displayed in the confirmation mail. In FIG. 5, the address “aaa@xxx.co.jp” specified in the TO field 52 and the address “ccc@yyy.co.jp” specified in the BCC field 54 are described in the confirmation mail as examples. The contents will be described in detail. In step S11 of FIG. 6, the address “aaa@xxx.co.jp” has acquired the name “XX Company Taro Tanaka”, so the name “XX Company Taro Tanaka” is described instead of the address. On the other hand, since the address “ccc@yyy.ao.jp” is not registered in the address DB 30, the name is not acquired in step S11. Therefore, not the name but the address is written as it is.

  For an address such as the address “ccc@yyy.ac.jp” whose name cannot be acquired in step S11 of FIG. 6, the organization name is acquired from the domain in step S13 of FIG. The organization name “Δ University” is acquired from the domain “yyy.ac.jp” of the address “ccc@yyy.ac.jp”, and the acquired organization name is described together with the address. As described above, by describing the name of the organization to which the address DB 30 is not registered, it is easy to notice that the company or the like designated by the confirmer is wrong, and at least send it. Sending emails to companies that shouldn't have been prevented.

  Subsequently, the presence / absence of registration in the address DB 30 of the address that is the destination of the planned outgoing mail and in the domain DB 31 of the domain included in the address that is the destination of the outgoing planned mail is described. Whether or not each is registered is determined by whether or not the name can be acquired in step S11 of FIG. 6 for the address, and whether or not the organization name can be acquired for the domain in step S13 of FIG. By displaying the presence / absence of registration, the confirmer can confirm that there is no registration in the address DB 30 and the domain DB 31 and prompt the registration.

  Furthermore, it is described in which of the TO column 52, the CC column 53, and the BCC column 54 the address is specified in the transmission scheduled mail in FIG. As a result, it is possible to prevent the address from being specified in the wrong column. Strict management of personal information is also required. Therefore, although it should be described in the BCC column, it may be a big problem to describe in another column. This is particularly effective in preventing such a serious problem.

  Finally, describe whether or not to encrypt the scheduled email. The information on whether to perform encryption uses the encryption flag acquired in step S11 of FIG. When “encrypt” is selected, the mail transmitted to the address is encrypted by the encryption means 24 at the time of transmission. On the other hand, if “not encrypted” is set, the mail transmitted to the address is transmitted without being encrypted.

  When an email is sent to an address designated as the other party, information on whether or not to encrypt is explicitly displayed, so that it is possible to prevent an omission of encryption and thus an information leakage. In addition, for an address that should be encrypted but is not encrypted in the confirmation mail, if the address is registered in the address DB 30, an update that adds encryption information to the address DB 30 Need to do. If it is not registered in the address DB 30, it must be registered together with the mail address.

  Thirdly, in the confirmation mail, the transmission date and time converted into the description format easy to confirm in step S14 in FIG. 6, and “year / month / day, hour / minute” in FIG. 7 are described. It is easy for the confirmer to visually identify that the emails with the same subject line are distinguished by describing the transmission date and time in an easy-to-confirm description format, and that the transmission date and time has been altered due to a virus. I can know.

  Fourth, the property of the attached file is described in the confirmation mail. However, it is not described when there is no attached file in the planned email to be sent. The properties of the attached file acquired in step S16 in FIG. 6, and the file name, size, presence / absence of password setting, and update date / time are described in FIG. By displaying the size of the attached file, it is possible to perform a check when the volume of mail that can be received by the transmission destination is limited, and it is possible to prevent a transmission error due to the capacity limitation. It should be noted that a transmission error can be prevented more reliably by storing in the address DB 30 a capacity that restricts reception of each address and displaying them together.

  In addition, by describing the presence / absence of password setting, the confirmer can easily confirm the presence / absence of password setting without opening the attached file, preventing information leakage caused by sending without password setting. be able to.

  Furthermore, by describing the update date and time, the confirmer can easily visually check whether or not the attached file is the latest one. As a result, it is possible to prevent sending an old version file. In addition to the information described above, the contents described in the text field 57 of the scheduled mail to be sent in FIG. 5 are displayed together, so that it is possible to check not only the other party etc. but also the text contents.

Returning to FIG. 4, step S3 and subsequent steps will be described.
S3: The confirmer confirms whether or not there is an error in the content of the scheduled mail to be transmitted by using the confirmation mail shown in FIG. As a result, if there is no error in the content, the confirmer inputs to the input means 3 that there is no error in the content, and the mail control means 12 accepts the input and moves the process to step S5. On the other hand, if there is an error, the confirmer does not input to the input means 3 that there is no error in content, and the process proceeds to step S4. Here, when the confirmation mail creating means 23 creates the confirmation mail, it is desirable to attach the scheduled mail to the confirmation mail. After confirming the confirmation email, both when sending the scheduled email and when modifying the scheduled email, it saves you from having to search for the email in the send list etc. and prevents you from selecting another email by mistake. Because. In the following description, it is assumed that the scheduled mail is attached to the confirmation mail.

  If there is no error in the content of the scheduled transmission mail presented in the confirmation mail, the confirmer inputs that fact through the input means 3. Thereafter, the mail determination means 21 passes the scheduled transmission mail that has been confirmed to be error-free by the confirmer to the mail transmission / reception means 14 as a transmission mail. For example, in the case of FIG. 7 (a), the confirmer opens the transmission scheduled mail shown in FIG. 5 attached to the confirmation mail in the case of FIG. The transmission button 50 shown in FIG. This is because the fact that the scheduled mail has been sent means that there is no error in the contents.

  Further, in the case of FIG. 7B, if the confirmer inputs that there is no error in the content of the planned email to be sent by the input means 3, there is no error in all pop-ups presenting the content of the planned email to be sent. That is, the confirmer inputs the information using the input means 3. In this case, after the confirmer confirms all pop-ups, the mail management unit 10 may instruct the transmission of the scheduled mail.

  By the way, whether the erroneous transmission preventing means 20 is a mail scheduled to be created as a confirmation mail or a transmission mail whose contents are confirmed by the confirmation mail and transmitted to the other party. It is necessary to make a judgment. This is because the scheduled mail and the transmitted mail are different in subsequent processing. The mail determination means 21 determines whether the mail delivered from the mail control means 12 is a transmission planned mail or a transmission mail. As a method for the mail determination means 21 to determine whether the mail delivered from the mail control means 12 is a scheduled transmission mail or a transmission mail, for example, a confirmation mail is created in the erroneous transmission prevention means 20. There is a way to remember.

  More specifically, the erroneous transmission preventing means 20 temporarily stores the destination and subject of the planned outgoing mail. The mail judging means 21 judges whether or not the destination stored in the temporary storage matches the subject when the mail is sent from the mail control means 12. Is determined to be a transmission mail to be transmitted to the mail transmission / reception means 14, and the transmission mail is transferred to the mail transmission / reception means 14. On the other hand, if they do not match, the mail determination means 21 determines that the mail is a transmission planned mail that is a confirmation mail creation target, and passes the transmission planned mail to the input content editing means 22. At the same time, the mail determination means 21 temporarily stores the destination and subject of this mail.

  S4: If the confirmer determines in step S3 that there is an error in the content of the mail, the confirmer corrects the scheduled transmission mail attached to the confirmation mail, and retransmits the mail. Executes step S1. Specifically, when the mail creation unit 11 recreates the scheduled transmission mail and the mail control unit 12 receives a transmission instruction for the redesigned transmission mail, the mail determination unit 21 executes Step S1.

S5: When the confirmer inputs that there is no error in the scheduled mail to be sent in step S3, the encryption means 24 encrypts from the address DB 30 based on the address designated as the mail partner. Get flags and encryption information.
S6: The encryption unit 24 determines whether or not there is an address whose encryption flag acquired in step S6 is “encrypted”.

S7: The encryption unit 24 encrypts the mail that is determined to be “encrypted” in step S6 by using the encryption information acquired in step S5.
S8: The mail determined to be “not encrypted” in step S6 is not encrypted, and the mail determined to be “encrypted” is transmitted to the other party as the mail encrypted in step S7.
