Claims (5)

If the message to be sent has an attachment, a determination unit determines whether or not the attachment contains predetermined important information. If it is determined that the attached file does not contain the important information, the storage unit stores the attached file in a predetermined storage service, If it is determined that the attached file contains the important information, a display control unit displays a screen for the user to confirm the important information, A creation unit that creates a message in which the attached file is deleted and the storage location of the attached file in the storage service is specified, A device for preventing accidental transmission.
If the message to be sent has an attachment, a determination unit determines whether or not the attachment contains predetermined important information. If it is determined that the attached file does not contain the important information, the storage unit stores the attached file in a predetermined storage service, If it is determined that the attached file contains the important information, the display control unit will not store the attached file in the storage service, but will instead display a screen for the user to confirm the important information. A device for preventing accidental transmission.
If the message to be sent has an attachment, a determination procedure for determining whether the attachment contains predetermined important information, If it is determined that the attached file does not contain the important information, a storage procedure is performed to store the attached file in a predetermined storage service. If it is determined that the attached file contains the important information, a display control procedure is provided to display a screen for confirming the important information. A creation procedure for creating a message that deletes the attached file and specifies the storage location of the attached file in the storage service, A method used by computers to prevent accidental transmissions.
If the message to be sent has an attachment, a determination procedure for determining whether the attachment contains predetermined important information, If it is determined that the attached file does not contain the important information, a storage procedure is performed to store the attached file in a predetermined storage service. If it is determined that the attached file contains the important information, a display control procedure is performed to display a screen for viewing the important information without storing the attached file in the storage service, A method used by computers to prevent accidental transmissions.
A program that causes a computer to function as a device to prevent accidental transmission as described in claim 1 or 2.

Description

This invention relates to a device for preventing erroneous transmissions, a method for preventing erroneous transmissions, and a program. As a technology to prevent the accidental sending of emails (hereinafter also simply referred to as "mail"), a technology is known that displays a confirmation screen to allow the sender to verify the validity of the recipient's address and attached files before sending the email. For example, Patent Document 1 discloses a technology that displays a confirmation screen to allow the sender to verify the validity of the recipient's address before sending the email, and prevents the email from being sent until the confirmation result on this screen is obtained. Incidentally, in recent years, instead of attaching electronic files (hereinafter simply referred to as files) directly to emails, there has been an increase in usage methods such as storing files in a storage service and then including the URL of the storage location (Uniform Resource Locator) in the email. Since this method of use is essentially the same as attaching the file itself to an email, it is considered to pose similar security risks. Japanese Patent Publication No. 2007-87327 This figure shows an example of the functional configuration of the email sending terminal according to this embodiment.This flowchart shows an example of the email sending process according to this embodiment.This figure shows an example of a submission confirmation screen.This flowchart shows an example of the important information determination process according to this embodiment.This figure shows an example of a screen for confirming important information.This figure shows an example of the functional configuration of a modified email sending terminal and an email misdelivery prevention server. The following describes one embodiment of the present invention. This embodiment describes an email sending terminal 10 capable of preventing accidental transmission of emails containing a file's storage URL. Here, "misdirected transmission" refers to sending an email unintentionally. For example, the cases described in (1) to (3) below constitute misdirected transmission. ） Furthermore, in addition to the above, the email sending terminal 10 according to this embodiment displays a screen (a screen for confirming important information, described later) for the user to confirm if the file (mainly the file stored at the location indicated by the above-mentioned storage URL) contains important information (e.g., personal information). This allows the user to be notified before sending the email if the file contains important information, making it possible to have the user confirm, for example, whether or not it is really okay to send the URL of the file's storage location. This embodiment describes email as an example, but this is just one example. This embodiment can also be applied to messaging applications such as instant messengers and chat applications. That is, it can be applied similarly when sending a message containing a file's URL via a messaging application, to prevent accidental sending as described in (3) above, or to notify the user that the file contains important information. Furthermore, since email applications (so-called mailers) for sending and receiving emails can be considered a type of messaging application, email also falls under the category of messages. Furthermore, while the files stored in the storage service (and files attached to emails) are primarily assumed to be document files, they are not limited to these; they may also be any electronic data, such as image files. <Overall configuration of email sending terminal 10> Figure 1 shows the functional configuration of the email sending terminal 10 according to this embodiment. As shown in Figure 1, the email sending terminal 10 according to this embodiment has an email creation unit 101, an erroneous transmission prevention processing unit 102, and a display control unit 103. Each of these units is realized, for example, by processing that one or more programs installed on the email sending terminal 10 cause to be executed by various computing devices such as a CPU (Central Processing Unit). For example, the email creation unit 101 can be realized by processing that an email application causes to be executed by the computing device. Also, for example, the erroneous transmission prevention processing unit 102 may be realized by processing that an erroneous transmission prevention application program different from the email application causes to be executed by the computing device, or by processing that a program that is added in or added on to the email application causes to be executed by the computing device. The display control unit 103 may be realized by processing that the above-mentioned erroneous transmission prevention application program causes to be executed by the computing device, or by processing that the above-mentioned add-in or add-on program cau
