Description

  The present invention relates to a technique for preventing erroneous transmission of electronic data.

  Various methods for preventing erroneous transmission when electronic data is transmitted by FAX or SMS (Short Message Service) in a public telephone network have been considered.

  For example, in Patent Document 1, the telephone number of the input destination is confirmed by referring to a telephone directory registered in the telephone as the destination.

  In Patent Document 2, the presence of transmission data is notified to a destination of transmission data, and transmission data is transmitted after confirmation on the destination side to prevent erroneous transmission.

  In Patent Document 3, a FAX transmission form in which a customer's FAX number is two-dimensionally encoded is printed with reference to a database storing information related to a customer who is a FAX transmission destination, and a document including the FAX transmission form is faxed. Send to central management system. Then, the FAX central management system decodes the two-dimensionally encoded FAX number and sends the document to the customer to prevent erroneous transmission.

  In Patent Literature 4, erroneous transmission is prevented by recommending destination candidates using a transmission history.

On the other hand, there is known a technique that allows an incoming call to be permitted or rejected by registering a transmission source that rejects the incoming call (see Non-Patent Document 1).

This program is stored in a storage device included in the relay apparatus 100, and can be recorded on a recording medium such as a magnetic disk, an optical disk, or a semiconductor memory, or provided through a network.

  FIG. 3 is an explanatory diagram illustrating examples of telephone numbers, user names, and unique IDs stored in the storage unit 110. The storage unit 110 stores user names and unique IDs in a one-to-one correspondence. Since a plurality of users may use the same telephone number, the storage unit 110 stores one or more unique IDs in association with one telephone number. Therefore, when the user name search unit 140 searches for a unique ID using a user name, the number of searched unique IDs is one. On the other hand, when the telephone number search unit 130 searches for a unique ID using a telephone number, one or more unique IDs are searched.

  The comparison processing unit 150 compares the unique ID searched by the user name search unit 140 with each of the unique IDs searched by the phone number search unit 130, and the unique ID searched by the user name search unit 140 is the phone number search unit 130. Is included in the retrieved unique ID.

  FIG. 4 is a block diagram showing the configuration of the transmission terminal 200. The transmission terminal 200 shown in the figure includes an operation user interface 210 for selecting electronic data to be transmitted and inputting a destination user name, telephone number or unique ID, a display 220 for displaying input information and status, call control, A telephone control unit 230 that transmits and receives information, a telephone information storage unit 240 that stores telephone information, and a data storage unit 250 that stores electronic data are provided. In this embodiment, a personal computer provided with input means such as a keyboard and a mouse is used as the transmission terminal 200. However, for example, a telephone and a mobile phone can also be used.

  FIG. 5 is a block diagram showing a configuration of receiving terminal 300. The receiving terminal 300 shown in the figure includes an operation user interface 310 for inputting a unique ID, selecting permission, and rejecting, a display 320 for displaying received electronic data, a telephone control unit 330 for performing call control and information transmission and reception, and the like. A telephone information storage unit 340 that stores telephone information is provided. In this embodiment, a telephone provided with a display device is used as the receiving terminal 300. However, for example, a personal computer or a mobile phone can also be used.

  Next, the operation of the electronic data relay system in this embodiment will be described. FIG. 6 is a sequence diagram showing the operation of the electronic data relay system in the present embodiment.

  First, the sender selects the electronic data stored in the data storage unit 250 using the display 220 of the transmission terminal 200 and the operation user interface 210, and inputs the destination telephone number and the destination user name (step). 101). FIG. 7 shows a display example of the display 220 of the transmission terminal 200 at this time.

  The input destination telephone number is transmitted to the telephone control unit 230, and the telephone control unit 230 refers to the telephone information registered in the telephone information storage unit 240 and obtains the telephone number of the transmission source. Then, the telephone control unit 230 transmits to the relay device 100, and transmits the transmission destination telephone number, the transmission destination user name, the electronic data, and the transmission source telephone number (step 102).

  The relay device 100 receives a transmission destination telephone number, a transmission destination user name, electronic data, and a transmission source telephone number via the public telephone network, and stores the electronic data in the electronic data storage unit 120. The comparison processing unit 150 compares the unique ID searched using each of the destination telephone number and the destination user name to determine whether or not the destination telephone number is correct (step 103). Details of processing for determining whether or not the destination telephone number is correct in the relay apparatus 100 will be described later.

  If the destination telephone number is correct, the relay device 100 sends the receiving terminal 300 using the telephone control unit 160 and transmits the destination user name (step 104). Thereby, the receiving terminal 300 knows that the electronic data with respect to the user of a transmission destination exists.

  Receiving terminal 300 that has received the destination user name displays a screen for prompting input of the destination user name and a unique ID corresponding to the user name on display 320 (step 105). FIG. 8 shows a display example of the display 320 of the receiving terminal 300 at this time.

  The receiver (transmission destination user) inputs his own unique ID using the operation user interface 310 of the receiving terminal 300 (step 106).

  The input unique ID is transmitted to the relay device 100 by the telephone control unit 330 (step 107).

  The relay device 100 receives the unique ID via the public telephone network, and compares the unique ID received by the comparison processing unit 150 with the unique ID corresponding to the destination user name (step 108). The recipient is authenticated by comparing the unique ID.

  When the comparison processing unit 150 determines that the received unique ID and the unique ID corresponding to the user name of the transmission destination match, the comparison processing unit 150 transmits the transmission source telephone number to the reception terminal 300 (step 109). At this time, the transmission source user name may be transmitted in addition to the transmission source telephone number, or the transmission source user name may be transmitted.

  Receiving terminal 300 that has received the telephone number of the sender displays the received telephone number on display 320 and prompts the user to select whether to permit or reject the display of the transmitted electronic data (step 110). FIG. 9 shows a display example of the display 320 of the receiving terminal 300 at this time.

  The recipient uses the operation user interface 310 of the receiving terminal 300 to select permission or rejection of electronic data display (step 111).

  When the recipient selects permission, the receiving terminal 300 notifies the relay device 100 that the electronic data reception is permitted by the telephone control unit 330 (step 112).

  When the relay device 100 receives the permission to receive via the public telephone network, it reads the electronic data to be transmitted from the electronic data storage unit 120 and transmits it to the receiving terminal 300 by the telephone control unit 160 (step 113). In addition, the transmission terminal 200 is notified that reception of electronic data is permitted (step 114).

  The receiving terminal 300 displays the electronic data received from the relay device 100 on the display 320 (step 115). FIG. 10 shows an example in which electronic data is displayed on the display 320 of the receiving terminal 300. Although an example in which still image data such as a map is transmitted as electronic data has been described in this embodiment, it is needless to say that text, voice, video, or the like may be used.

  On the other hand, when receiving a notification from the relay device 100 that the receiver has permitted the reception of the electronic data, the transmitting terminal 200 displays that fact on the display 220 of the transmitting terminal 200 (step 116). FIG. 11 shows a display example of the display 220 of the transmission terminal 200 at this time.

  Thus, via the relay device 100, electronic data can be transmitted by designating a receiving user while preventing erroneous transmission. In particular, it is suitable for a transmission / reception service of electronic data that has a strong request for a destination and a request for designation by a receiving user.

  If the comparison processing unit 150 determines in step 103 that the destination telephone number is incorrect, the relay device 100 transmits an error to the transmission terminal 200. The transmission terminal 200 that has received the error displays on the display 220 that the telephone number or the destination user name is incorrect.

  In step 109, when determining that the unique ID received by the comparison processing unit 150 does not match the unique ID corresponding to the transmission destination user name, the relay device 100 transmits an error to the receiving terminal 300. The receiving terminal 300 that has received the error displays on the display 320 that the unique ID is not correct.

  In step 112, when the recipient selects rejection, the receiving terminal 300 transmits an electronic data reception rejection message to the relay device 100 by the telephone control unit 330. The relay apparatus 100 notifies the transmission terminal 200 that reception of electronic data has been rejected, and the transmission terminal 200 displays on the display 220 that reception of electronic data has been rejected.

  In step 104, in addition to the transmission destination user name, the transmission source user name is transmitted to the reception terminal 300, so that the reception terminal 300 displays the transmission source user name as shown in FIG. Is possible.

  When a mobile phone is used as the receiving terminal 300, a unique ID is generated using the mobile phone ID registered in the mobile phone in response to the unique ID input request, and transmitted to confirm the destination user. You may do it. Alternatively, a unique ID stored in the IC card may be read from an IC card reader to generate a unique ID. For example, a unique ID may be stored in a non-contact IC chip mounted on a mobile phone, and a unique ID may be generated using the unique ID.

  Next, a process (step 103 in FIG. 6) in which the relay apparatus 100 determines whether or not the destination telephone number is correct will be described with reference to the flowchart shown in FIG.

  Receiving the transmission destination telephone number, user name, electronic data, and transmission source telephone number from the transmission terminal 200, the telephone control unit 160 transmits the transmission destination user name to the user name search unit 140 (step 201). The destination telephone number is transmitted to the telephone number search unit 130 (step 202).

  The user name search unit 140 searches the storage unit 110 for a unique ID corresponding to the destination user name (step 203). On the other hand, the telephone number search unit 130 searches the storage unit 110 for a unique ID associated with the destination telephone number (step 204). Since a plurality of unique IDs may be associated with a telephone number, one or more unique IDs are obtained.

  If the user name search unit 140 or the telephone number search unit 130 cannot obtain a unique ID (steps 205 and 206), an error is transmitted to the transmission terminal 200.

  The comparison processing unit 150 compares the unique ID searched by the user name search unit 140 with the unique ID searched by the telephone number search unit 130, and determines whether there is a matching unique ID (step 207). ). If there is a matching unique ID, the telephone number of the transmission destination and the user name of the transmission destination are correct, so that the receiving terminal 300 is notified that electronic data to be transmitted exists (step 104 in FIG. 6).

  Thus, by determining whether or not the unique ID corresponding to the user name of the transmission destination is included in the unique ID associated with the telephone number of the transmission destination, the telephone number of the transmission destination of the electronic data is correct. Guaranteed.

  Therefore, according to the present embodiment, when electronic data is transmitted, the relay device 100 compares the unique ID corresponding to the user name of the transmission destination with the unique ID associated with the telephone number of the transmission destination. By searching for whether there is a unique ID to be transmitted, it is possible to prevent erroneous transmission of electronic data.

  According to the present embodiment, by receiving the electronic data reception permission from the receiving terminal 300, the receiver can select reception permission or rejection each time electronic data is transmitted.

  According to the present embodiment, the relay device 100 receives the unique ID corresponding to the transmission destination user name from the receiving terminal 300 and authenticates the transmission destination user, so that other users can view the electronic data. Things will disappear.

  According to the present embodiment, by generating the unique ID using the mobile phone ID, the user does not need to input the unique ID.

[Second Embodiment]
The electronic data relay system in the second embodiment has the same basic configuration as the electronic data relay system in the first embodiment. Hereinafter, differences from the first embodiment will be described.

  The second embodiment is different from the first embodiment in that a sender's unique ID is input when the sender transmits electronic data (step 101 in FIG. 6).

  The relay device 100 that has received the sender's unique ID searches the sender's user name from the unique ID, and sends the sender's user name together with the destination user name (step 104 in FIG. 6). As a result, it is ensured that the sender is correct, and the sender can be specified even when a plurality of users share the telephone number of the sender. The second embodiment is a system applicable to a service having a strong demand for guaranteeing the identity of a file transmission source.

  Therefore, according to the present embodiment, by transmitting the sender's unique ID when the transmission terminal 200 transmits electronic data, the relay device 100 can ensure that the sender is correct. .
