Insert the previous name and its mail address, and insert the title (SUB), attached file name, and file size of the sent e-mail in the corresponding parts of the multiple “xxx” in the body 222. In addition, in order to access the attached file, a URL specifying the attached file storage area is described, and an electronic mail is generated.

  Subsequently, the information processing apparatus 100 distributes an e-mail describing a notification about the attached file to be downloaded to the mail box of the destination mail server 15 (step S20).

Thereafter, when it is detected at the transmission destination terminal that the electronic mail has been distributed, the transmission destination terminal reads out the distributed electronic mail stored in the mail box by the operation of the operator.
Thereafter, when the operator reads the e-mail and wants to download the attached file, the operator operates an input unit (not shown) of the terminal and displays the initial authentication screen 300 shown in FIG. 11 (not shown). When the input is made, the terminal transmits a message to that effect to the information processing apparatus 100.

  When the information processing apparatus 100 receives a request to transmit the initial authentication screen 600 from the transmission destination terminal, the information processing apparatus 100 transmits a Web page constituting the initial authentication screen 600 to the transmission source terminal (step S21).

  When a user ID is input to the user ID field 301 of the received initial authentication screen 600 and the “login button” 602 is clicked by the transmission source user, the terminal transmits the user ID to the information processing apparatus 100.

  Upon receiving the user ID from the terminal (step S22), the information processing apparatus 100 generates a password that can be temporarily used by applying a random number, for example, and displays a password display screen shown in FIG. 12 that displays the generated path. The constituent web page is transmitted to the terminal (step S23).

The terminal receives the Web page that constitutes the password display screen, and displays the password display screen 610 on the display unit.
Thereafter, the user clicks an “OK” button 612 after storing or refraining from the password displayed on the password display screen.
Then, the terminal transmits to the information processing apparatus 100 that the password has reached the user.

Then, when the information processing apparatus 100 receives that the password has reached the user (step 24), the uniquely encrypted encryption information (“ARTCE” in FIG. 12A) shown in FIG. 12 is embedded. The web page constituting the authentication screen 620 is generated, and the generated web page is transmitted to the user terminal (step S25).
The encryption information is an alphabet generated based on the generated random number.

When the user terminal receives the Web page received from the information processing apparatus 100, the user terminal displays an authentication screen 620 in which encryption information is embedded on the display unit.
The user inputs the previously transmitted password in the password input field 623 in the authentication screen displayed on the user terminal and clicks the “OK” button 622.
Then, the user terminal transmits an authentication screen 620 displayed on the display unit to the information processing apparatus 100.

When receiving the authentication screen 620 from the user terminal, the information processing apparatus 100 reads the password input to the received authentication screen and the encryption information embedded in the authentication screen (step S26).
Next, the information processing apparatus 100 uses the encrypted password embedded in the authentication screen 620 in which the read password is the password transmitted to the user terminal first, and the received encrypted information is transmitted to the user terminal first. It is determined whether or not they are the same (step S27).

  If the information processing apparatuses 100 determine that both are the same (step S27; YES), the information processing apparatus 100 authenticates that the user is a legitimate user by assuming that there is no so-called “spoofing” (step S28), and FIG. A web page constituting the process selection screen 630 shown in (b) is generated, and the generated web page is transmitted to the user terminal (step S28).

When the user terminal configures the process selection screen 630 from the information processing apparatus 100 and receives a Web page, the user terminal displays the process selection screen on the display unit.
When the user inputs a URL for downloading an attached file in the URL column 631 described in the process selection screen 630 displayed on the display unit of the user terminal and clicks an “OK” button 632, the URL The URL input in the column 631 is transmitted to the information processing apparatus.

  When receiving the URL for downloading the attachment file from the user terminal, the information processing apparatus 100 reads the attachment file from the attachment file storage area 24, transmits the read attachment file to the user terminal (step S29), and performs processing. finish.

  When receiving the attached file from the information processing apparatus 100, the user terminal stores the received attached file in the storage unit.

  If the information processing apparatus 100 determines in step S27 that the encrypted information is not the same (step S27; NO), the information processing apparatus 100 transmits a screen (not shown) indicating that the attached file cannot be downloaded (not shown). Step S30), the process ends.

  The information processing apparatus 100 according to this embodiment compares the extracted security level with the virus level stored in advance in the virus level storage area 23. If the extracted security level is equal to or lower than the virus level, the information is received. Since the e-mail is discarded, the risk of receiving an infected e-mail can be reduced.

  When the information processing apparatus 100 of this embodiment detects an e-mail that is likely to be infected by a computer virus, the information processing apparatus 100 sends an e-mail that describes that the e-mail is likely to be infected to the sender of the e-mail. Since it is transmitted, the spread of computer viruses can be prevented.

  According to the information processing apparatus 100 according to this embodiment, when an e-mail having an attachment file having a large file size is transmitted, the attachment file is separated from the e-mail, and the attachment file is separated into the e-mail. Since the e-mail describing the information for specifying the attached file, its size, and the URL for accessing the attached file is transmitted to the recipient, it is possible to eliminate the hindering of receiving the subsequent e-mail.

  Further, the information processing apparatus 100 according to this embodiment transmits a password set in advance with a random number to the user terminal, then transmits an authentication page including uniquely encrypted encryption information to the user terminal, and transmits it first. If the password entered in the authentication and the encrypted information is the same, the user is authenticated as a legitimate user, so that the authentication accuracy can be obtained more than the POP authentication.

Next, the information processing apparatus 100 reads out the e-mail stored in the e-mail storage area 27, reads the title and the e-mail transmission source from the header of the e-mail, and stores them in the read storage unit 12. (Step S42).

  Subsequently, the information processing apparatus 100 reads out the email stored in the email storage area 27 and checks whether or not it is infected with a virus (step S43). When the electronic mail is not infected with a virus (step S43; NO), the information processing apparatus 100 extracts only the attached file from the electronic mail stored in the electronic mail storage area 27, and extracts the extracted attached file. The file is stored in the attached file storage area 43 (step S44).

Thereafter, the information processing apparatus 100 transmits a text e-mail obtained by removing the attached file from the e-mail to the user terminal (step S45).
Next, the information processing apparatus reads the template e-mail 710 shown in FIG. 15B from the template e-mail storage area 25 in the external storage device 20, and uses the read template e-mail 710 as shown in FIG. The e-mail 730 describing the notification about the attached file to be downloaded is generated (step S46).
That is, the information processing apparatus 100 stores the name of the transmission source stored in the storage unit 12 and its mail in the transmission destination (TO) and transmission source (FROM) in the template electronic mail 420 shown in FIG. The address, the name of the destination and its mail address are inserted, and the title (SUB) of the transmitted email, the name of the attached file, In order to insert a file size and to access an attached file, a URL specifying an attached file storage area is described, and an e-mail 730 is generated.

  Subsequently, the information processing apparatus 100 distributes the e-mail 730 describing the notification about the attached file to be downloaded to the mail box of the destination mail server 15 (step S47).

After that, when it is detected that the e-mail 730 has been delivered at the destination terminal, the destination terminal reads the delivered e-mail 730 stored in the mailbox by the operation of the operator.
After that, the operator reads the e-mail 730 and, when he / she wants to download the attached file, operates the input unit (not shown) of the terminal and displays the initial authentication screen 600 shown in FIG. 11 (not shown). When the input is made, the terminal transmits a message to that effect to the information processing apparatus 100.

  When the information processing apparatus 100 receives a request to transmit the initial authentication screen 600 from the transmission destination terminal (step S48), the information processing apparatus 100 transmits a Web page constituting the initial authentication screen 600 to the transmission source terminal (step S48).

The web page constituting the authentication screen 620 is generated, and the generated web page is transmitted to the user terminal (step S52).
The encryption information is an alphabet generated based on the generated random number.

When the user terminal receives the Web page received from the information processing apparatus 100, the user terminal displays an authentication screen 620 in which encryption information is embedded on the display unit.
The user inputs the previously transmitted password in the password input field 623 in the authentication screen displayed on the user terminal and clicks the “OK” button 622.
Then, the user terminal transmits an authentication screen 620 displayed on the display unit to the information processing apparatus 100.

When receiving the authentication screen 620 from the user terminal, the information processing apparatus 100 reads the password input to the received authentication screen 620 and the encryption information embedded in the authentication screen 620 (step S53).
Next, the information processing apparatus 100 uses the encrypted password embedded in the authentication screen 620 in which the read password is the password transmitted to the user terminal first, and the received encrypted information is transmitted to the user terminal first. It is determined whether or not they are the same (step S54).

  If both the information processing apparatuses 100 determine that they are the same (step S54; YES), the information processing apparatus 100 authenticates that the user is a legitimate user by assuming that there is no so-called “spoofing”, and FIG. A web page constituting the process selection screen 630 shown is generated, and the generated web page is transmitted to the user terminal (step S55).

When the user terminal configures the process selection screen 630 from the information processing apparatus 100 and receives a Web page, the user terminal displays the process selection screen 630 on the display unit.
When the user inputs a URL for downloading an attached file in the URL column 631 described in the process selection screen 630 displayed on the display unit of the user terminal and clicks an “OK” button 632, the URL The URL input in the column 631 is transmitted to the information processing apparatus.

  When receiving the URL for downloading the attached file from the user terminal, the information processing apparatus 100 reads the attached file from the attached file storage area 24, transmits the read attached file to the user terminal (step S56), and performs processing. finish.

  When receiving the attached file from the information processing apparatus 100, the user terminal stores the received attached file in the storage unit.

  If it is determined in step S54 that the encryption information is not the same (step S54; NO), a screen indicating that the attached file cannot be downloaded is transmitted (step S57), and the process ends.

  In step S43, if a virus is infected (step S43; YES), the information processing device 3 specifies the name of the virus infected with the electronic mail (step S58), and stores the specified virus name in the storage unit. 12 (step S59).

Next, the information processing apparatus 3 deletes the email stored in the email storage area 27 (step S60).
Subsequently, the information processing apparatus 3 generates an email stored in the notification email storage file 26 for notifying that the received email is infected with a virus (FIG. 15A). A template e-mail 700 as shown in FIG. 18 is read out, and a notification e-mail 720 as shown in FIG. 18A is generated based on the read template e-mail 700 ( Step S61).

That is, the information processing apparatus 100 describes the email address of the sender that transmitted the infected email in the destination column 723 of the header 721 of the template email.
Further, the information processing apparatus 3 generates a notification e-mail 720 by describing a title in a location 724 and a virus name in a location 725 in the body part 722 of the template e-mail.

  When the information processing apparatus 100 generates the notification e-mail, the information processing apparatus 100 transmits the generated e-mail 720 to the transmission source of the e-mail previously infected with the virus (step S62), and ends the process.

According to the information processing apparatus 100 of this embodiment, when it is determined that the received e-mail is infected with a virus, the received e-mail is discarded and the e-mail is transmitted to the virus as a source of the e-mail. Since it is informed that it is infected, the sender can know that the email is infected with a virus.
Therefore, it is possible to prevent the spread of virus infection by transmitting without being aware that the virus is infected.
