Further, the telegraph file delivery system 5 of the present embodiment does not have an e-mail transmission function such as an SMTP (Simple Mail Transfer Protocol) server, but may be provided therein. Here, an example of the e-mail 800 is shown. “The customer has received an electronic file. Please visit http://www.sample.com/cgi/posta.dll?pu=233-33982-FIAAAV4 and download it before accessing the above URL. Please call 03-1234-5678 while notifying the caller's phone number from your mobile phone 090-1111-1111. If you access the above URL within 30 seconds after calling, download the file. I can do it."

Next, the operation of the module related to the electronic file receiving side will be described.

The caller telephone number reception module 400 receives a dial from the mobile phone 60 accompanied by a caller telephone number notification via the telephone line interface 120, and sets the caller telephone number and the date and time when the dial is received as the dial incoming date and time. Deliver to the writing module 410. On the other hand, caller telephone number reception module 400 rejects dialing from mobile phone 60 without caller telephone number notification. Since the caller telephone number reception module 400 can acquire the caller number only by receiving a dial from the mobile phone 60 or the fixed telephone 50, the electronic file delivery system 5 is not necessarily connected to the mobile telephone 60 or the fixed telephone 50. It does not have to be in a call state.

The dial incoming date / time writing module 410 accepts the caller telephone number and the date / time when the dial was received from the caller telephone number reception module 400. Next, the dial incoming date / time writing module 410 selects a record in which the received caller telephone number matches the electronic file recipient telephone number 5206 of the file information storage table 520 from the file information storage table 520. Then, the dial arrival date / time writing module 410 stores the accepted dial reception date / time in the dial arrival date / time 5207 of the selected record. When a plurality of files are transmitted for one telephone number, the dial arrival date / time writing module 410 selects a plurality of records from the file information storage table 520, so that all the selected records are recorded. The dial reception date and time is stored in the dial incoming date and time 5207.

FIG. 7 is a configuration diagram of the file information storage table 520 of the electronic file delivery system 5 according to the first embodiment. The file information storage table 520 in this explanatory diagram is after receiving a dial from the file recipient. Specifically, this is the file information storage table 520 after the caller telephone number reception module 400 receives a dial from “090-1111-1111” at “13:45:36 on December 1, 2005”. In this case, the dial arrival date / time writing module 410 selects, from the file information storage table 520, records 521 and 523 in which “090-1111-1111” matches the electronic file recipient number 5206 of the file information storage table 520. . Then, “December 1, 2005 13:45:36” is stored in the dial arrival date and time 5207 of the selected records 521 and 523. Thereby, the records 521 and 523 of the file information storage table 520 shown in FIG. 6 are updated to the records 531 and 533 of the file information storage table 520 shown in FIG.

Returning now to FIG. The file download web page sending module 300 receives access from the personal computer 20 operated by the user who has received the e-mail 800 via the data communication interface 110. Then, the URL for which access has been accepted is delivered to the download URL access permission determination module 310, and a request for access permission is requested.

The download URL access permission determination module 310 accepts the URL from the file download web page sending module 300. Next, the file ID, recipient ID, and URL ID are read from the accepted URL. Next, the read URL ID is delivered to the file information reading module 320, and a request is made to read information related to the URL ID from the file information storage table 520. For example, the download URL access permission determination module 310, when there is an access of “http://www.sample.com/cgi/posta.dll?pu=233-33982-FIAAAV4”, relates to “FIAAAV4” of the URL ID. The file information reading module 320 is requested to read the information.

The file information reading module 320 accepts the URL ID from the download URL access permission determination module 310. Next, a record in which the accepted URL_ID matches the URL_ID 5201 of the file information storage table 520 is selected from the file information storage table 520. Next, a file ID 5202, a recipient ID 5203, a dial incoming date / time 5207, a file name 5205, and a file storage destination folder path 5204 are extracted from the selected record. Here, the extracted value is a response 730. Then, the file information reading module 320 transmits a response 730 to the download URL access permission determination module 310. If no value is stored in the dial incoming date / time 5207 or if a record matching the URL_ID 5201 does not exist in the file information storage table 520, the file information reading module 320 sends the URL access permission determination module 310 for downloading. Notify that. Here, an example of the notification method is shown. If no value is stored in the dial incoming date / time 5207, the file information reading module 320 transmits a response 730 in which the dial incoming date / time 5207 is “1/01/1900 00:00:00” which is an invalid value. If there is no record that matches the URL_ID 5201, the file information reading module 320 transmits a response 730 in which the file ID 5202 included in the response 730 is blank. Note that other methods can be used as the notification method as long as the purpose is achieved.

The download URL access permission determination module 310 accepts the response 730 from the file information reading module 320 and determines whether or not to permit access to the URL received from the file download web page sending module 300. When permitting access, the download URL access permission determination module 310 transmits a response 730 to the file download WEB page sending module 300. On the other hand, when the access is not permitted, the download URL access permission determination module 310 notifies the file download WEB page sending module 300 of the disapproval. For example, the download URL access permission determination module 310 notifies the file download WEB page transmission module 300 of the response 730 with the file storage destination folder path 5204 included in the response 730 blank, thereby notifying the non-permission. Note that other methods can be used as the non-permission notification method as long as the purpose is achieved. Here, the download URL access permission determination module 310 permits access to the URL received from the file download WEB page sending module 300 when all of the following three conditions are satisfied.
(Condition 1) The date and time when the response 730 is accepted is within a certain time from the dial incoming date and time 5207 included in the response 730.
(Condition 2) The file ID 5205 included in the response 730 matches the file ID included in the URL received from the file download WEB page sending module 300, and the recipient ID 5203 included in the response 730 and the file download WEB page The receiver ID included in the URL received from the sending module 300 matches.
(Condition 3) At least one of a notification that no value is stored in the dial incoming date and time 5207 and a notification that there is no record that matches the URL_ID 5201 have not been received from the file information reading module 320.

For a certain period of condition 1, a shorter file can realize safe file transfer. This is because the date and time when the file download URL was accessed by a person who was not the original electronic file recipient who eavesdropped on the e-mail 800 is less likely to be included in the date and time when access is permitted. On the other hand, if the fixed time of condition 1 is too short, the original electronic file recipient cannot secure enough time to access the file download URL from the dial. . In the present embodiment, the fixed time for Condition 1 is 30 seconds, but it is left to the practitioner of the present invention to balance safety and convenience.

Here, an example is shown in which the download URL access permission determination module 310 determines that access is permitted. On December 1, 2005, 13:45:36, an incoming call arrived from 090-1111-1111 to 03-1234-5678 allocated to the telephone line interface 120, followed by “http://www.sample.com. /Cgi/posta.dll?pu=233-33982-FIAAAV4 ", and the download URL access permission determination module 310 receives the file information reading module 320 from 13:45:50 on December 1, 2005. File ID “233”, recipient ID “33982”, dial arrival date and time “2005/12/1 13:45:36”, file name “SecretFile.txt”, and file storage destination folder path “C: ¥ file ¥ FIAAAV4” I received a response. Since the response was accepted on December 1, 2005, 13:45:50, 30 seconds or more have not passed since the dial arrival date and time “2005/12/1 13:45:36”, condition 1 is satisfied. Visited http: // www. sample. com / cgi / posta. dll? The file ID “233” and the recipient ID “33982” included in pu = 233-33982-FIAAAV4 are equal to the file ID “233” and the recipient ID “33982” received from the file information reading module 320, and the condition 2 is satisfied. Fulfill. At least one of the notification that the dial arrival date / time is not written in the record of URL ID “FIAAAV4” requested to be read by the file information reading module 320 and the notification that there is no matching record are not received, and the condition 3 is satisfied. Therefore, since all three conditions are satisfied, the download URL access permission determination module 310 determines that access to the URL is permitted.

In condition 1 of the present embodiment, the interval between the dial arrival date and time included in the response 730 and the date and time when the download URL access permission determination module 310 accepts the response 730 is used.
