2. Description of the Related Art Due to the widespread use of mobile phones and the like, services for performing regular subscription-type information distribution using electronic mail are rapidly spreading. However, for this reason, it is necessary to notify the service provider of the email address that is personal data, and even if the information is no longer needed by the user, the service provider unilaterally delivers the email and the user must receive it. There is a problem of not getting.

As a measure against this problem, for example, Japanese Patent Application No.
As described in JP-A-280728, there is a method in which a mail from a specific sender mail address is registered as a reception refusal address in a mail server and the user is not notified.

However, there are the following problems with respect to this countermeasure.

If the service provider leaks the user's e-mail address to a peer, or if the service provider himself changes the sender's e-mail address, the e-mail will be sent from an unspecified sender's e-mail address. However, there is no means to prevent the reception except that the user judges that it is an unnecessary mail and registers the reception refusal every time.

Although this problem can be dealt with by changing the user's mail address, it is not an effective method because the originally required mail cannot be received.

Next, the operation of the electronic mail transmission / reception method with the unwanted mail reception prevention function of the first embodiment will be described with reference to FIGS. 2, 3, and 4.

FIG. 2 shows a sequence from the user 10a to the registration of the information distribution by mail from the service provider 20X.

When the user 10a makes a registration request for information distribution to the service provider 20X as in the sequence 1, the address is notified as the destination of the mail, but the sequence 2
At the mail server 30a, the temporary allocation address No. 1 is generated instead of the address 11A permanently used by the user 10a, and the information is stored in the user information 32a storing the information of the user 10a in sequence 3. In sequence 4, the service provider 20X is notified of the temporary allocation address No. 1 as the transmission source.

Therefore, upon completion of registration at the service provider 20X, the destination of the mail is the temporarily assigned address No. 1 as in Sequence 5. Upon receiving the notification of registration completion, the temporary allocation address No. 1 is added to the user information 32a created as shown in sequence 6 on the mail server 30a.
The address 21J, which is the transmission source address of the service provider 20X of the service providing source, is linked and stored.

In addition, the delivery registration completion notification to the user 10a does not require the user 10a to recognize the existence of the temporarily assigned address No. 1, so that the registration at the address 11A is notified as in sequence 7. To do. This completes the registration sequence.

FIG. 3 shows a sequence until the mail is delivered from the service provider 20X to the user 10a.

Service provider 20X as in sequence 8
When a mail is sent from the sender as the address 21J and the recipient as the temporarily assigned address No. 1, an address permanently used by the user in the memory 31a in the mail server 30a as in Sequence 9 Search for the corresponding address from the temporarily assigned addresses.

In the case of FIG. 3, since the matching address exists in the user information 32a which is the information of the user 10a, the source address is the address 21J and the destination address is the address for the user 10a as in the sequence 10. 11A is transmitted. The user 10a receives the mail, and the delivery sequence is completed.

FIG. 4 shows a sequence when the reception refusal request from the address 21J is issued by the user 10a.

When the user 10a makes a request for refusal of reception to the refusal destination address 21J as in the sequence 11, the mail server 30a searches the information of the address 21J in the user information 32a in the sequence 12 and links it. The temporary allocation address No. that is the attached information.
The data including 1 is deleted.

As described above, the user 10a and the service provider 20
Temporary assigned address 1 used as a destination from X
The link deletion of is completed.

FIG. 5 shows a mail transmission sequence from the service provider 20X to the user 10a after data deletion.

The service provider 20 as in sequence 13
When a mail is transmitted from X with the address 21J as the transmission source and the temporary allocation address No. 1 as the transmission destination, the mail server 30a causes the memory 31
The address permanently used by the user in a and the address that has been temporarily assigned are searched for the existence of the corresponding address.

In the case of FIG. 5, since the link between the user 10a and the temporary allocation address No. 1 has already been deleted,
If there is no corresponding address, an error mail with no corresponding address is transmitted to the address 21J as in sequence 15. After that, the mail from the service provider 20X is not delivered to the user 10a.

In FIG. 6, distribution registration has been completed for the service provider 20X having the address 21J and the service provider 20Y having the address 21K.
A state in which a reception refusal request is made to J is shown.

In this case, mails from the service provider 20Y, which sends the temporarily assigned address No. 2 as the destination, and the user 10b, who directly sends the address 11B to the destination, can be received, but from the service provider 20X. Since the destination of the email is the temporarily assigned address No. 1, the email is not delivered to the user 10a.

When the service provider 20X changes the source address to the address 21L, the user 1
Even if the information of 0a is leaked to the service provider 20Z, only the information of the temporarily assigned address No. 1 can be held as the destination address, so that the mail is not delivered to the user 10a.

As described above, in the electronic mail transmission / reception method with the unwanted mail reception prevention function of the first embodiment, the mail server manages the link between the temporarily assigned address and the user's address. It is possible to receive mails from service providers without distinguishing them from conventional mails without notifying to.

In addition, when the mail reception from the specific service provider is rejected by the request from the user, the mail server deletes the temporarily assigned address and the user having the corresponding address does not exist in the mail server, and the address is invalid. Therefore, the mail from the service provider to the temporary allocation address will not be delivered to the user thereafter.

Further, even if the service provider changes the address of the transmission source or leaks the address information to other peers, the address designated by the service provider as the transmission destination is the deleted temporary allocation address. , The mail is not delivered to the user.

FIG. 7 shows a block diagram of a method for sending and receiving electronic mail with a junk mail reception preventing function according to the second embodiment of the present invention.

The service provider 20Z that is not the service provider 20X linked to the mail server 30a
Therefore, when an email is sent with the temporary assigned address No. 1 as the destination, the temporary assigned address No. 1
Is information that only the mail server 10a and the service provider 20X can know, so it can be known that the service provider 20X has leaked user information, and can be detected as an unauthorized sender. Based on this information, it is possible to take measures such as warning to the service provider who has leaked unauthorized information.

A terminal is provided for the user, mail server, and service provider in the first and second embodiments, and transmission / reception is performed by this terminal.

[0044]

According to the method for sending and receiving e-mail with the junk e-mail reception prevention function of the present invention, when a destination is requested to send information by e-mail, a predetermined address is notified to the destination terminal by the mail server. Because I decided to
When sending a mail, it is possible to request the sending of information without notifying the other party of the mail address used by the user, and then suppressing unnecessary reception of mail.

Further, since the predetermined address is an address temporarily allocated and generated by the mail server when the transmission of the information is requested to the transmission destination, a temporary mail is transmitted to the transmission destination. Notify the address,
You can easily refuse to receive mail from the other party.

Since the predetermined address is linked to the destination and stored in the mail server, unnecessary mail reception can be surely suppressed.

Since the link of the temporarily assigned address linked to the destination address requested to be rejected by the user is to be deleted, the destination e-mail recipient changes the source address. Even if the recipient of the email leaks the user's address, the recipient of the email can be reliably refused.

When the mail server notifies each of the plurality of destination terminals of the predetermined address, the link with the predetermined address linked to the specific destination address is deleted. As a result, it is possible to receive the necessary emails and suppress the unnecessary emails.

Further, when the mail server sends a mail from a sender that is not a recipient linked to the mail server to the predetermined address as a recipient, the sender is illegal. Since it is detected as the sender, unnecessary mail reception can be suppressed, and a service provider who leaks mail information to another person can be easily found.
