Abstract

<P>PROBLEM TO BE SOLVED: To obtain an electronic mail transfer system wherein each of users can easily send electronic mail to each other without notifying a partner about an electronic mail address (original address) provided by a general telecommunications entrepreneur or the like. <P>SOLUTION: Between both a mail sender and a mail recipient, specific transmission destination mail addresses are issued, and in the middle of them, an address translation/transfer server is provided as a mediator. The server translates a transmission source address (From address) or the like so that both the sender and the recipient can communicate with each other without being notified about their original addresses. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention provides privacy protection by issuing a mail address used only between the parties that can be contacted to the other party without notifying each other of the mail address provided by a general telecommunications carrier. It relates to a mail delivery system that can.

Traditionally, if you tell others about your e-mail address, the e-mail address may spread from another person to another person, and it may be annoying that your unsolicited and unintended partner may know your e-mail address. This is one of the factors that generate mail.
At this time, referring to the sender information (From address) of the mail address, the list type that individually prohibits the incoming from the designated mail address or can receive only the incoming from the designated mail address. Mail filtering technology is well known.
Generally, these are called a “reception rejection list” or a “reception permission list”.

Conventional list-type mail filtering technology refers to the e-mail source mail address. Therefore, even if the recipient of the mail creates a “rejection rejection list”, if the sender of the junk e-mail frequently changes the sender information (From address), it will pass through this, and the junk e-mail Had a problem with incoming calls.
On the other hand, if the recipient of the email creates a “reception permission list”, if the recipient who intended the delivery changes the email address by changing the telecommunications carrier, etc., the recipient will send an email. There was a problem that could not be received.
For this reason, it has become a social situation in which it is difficult for only a small number of other reliable parties to notify the e-mail address, and the original convenience of e-mail is impaired.
The present invention has been made to solve the above problems.

A mail server for address conversion / forwarding that issues a unique destination mail address between both mail senders and senders and acts as a bridge between them is established.
This “address conversion / forwarding mail server” mutually converts source information (From: address) and destination information (To: address) so that both parties can contract with each other. Communication can be established without notifying each other of addresses (hereinafter referred to as “original addresses”).
When we send mail to you, we specify that you specify the recipient's email address as “your identity code”, “your identity code”, “authentication code” and “forwarding mail server operation”. ”'S domain” is concatenated with a separator. The mail server for forwarding shall forward the mail only when the association between the combination of Party A and B and the authentication code is recognized.

The Web server in this system is assumed to have the user register an original address and password and issue a user identification code.
The issued identification code is displayed or notified to the user on the screen and by e-mail.

  If it is assumed that the other party who wants to know the e-mail address cannot be requested to register on this system, the registered user can access the other party's website from the "User Information Management Web Server" on this system. It shall be possible to give an identification code to an email address or domain.

  The “User Information Management Web Server” in this system designates the identification code of the corresponding system when a user receives an unpleasant mail using this system, and performs subsequent mail delivery. It shall be possible to make a stop or list type regulation.

"User information management Web server" changes the mail address of the forwarding destination by entering the identification code and password when the original address used by the user is changed and accessing this Web server It shall be possible. As a result, for example, even when a mobile phone of another company is replaced, it is possible to continue using the same mail address.
The present invention is an e-mail delivery system having the above-described configuration and taking privacy and convenience into consideration.

  By using this system, it is possible to effectively block unpleasant mail called so-called spam mail, and when the user's email address is leaked, the first leakage path of the email address can be identified, and Reachability can be maintained even when the e-mail address (original address) of the telecommunication carrier used by the user is changed, thereby ensuring comfort and convenience in using e-mail. it can.

Embodiments of the present invention will be described below.
(A) The registered user (1) sends an e-mail (2) to the “address conversion / forwarding mail server”. Thereafter, the “address conversion / forwarding mail server” performs address conversion (3). The mail address of the transmission source and the transmission destination is changed from the original mail. The sender mail address is composed of two user recognition codes, authentication codes, and “address conversion / forwarding mail server operator domain”. The destination mail address is converted to the address of the registered user (recipient) registered in the “address conversion / forwarding mail server”.
When each conversion is completed, the mail is transferred to the registered user (5) on the receiving side. (If you reply to this e-mail, the e-mail is delivered to the other party via the "address conversion / forwarding mail server", so the subsequent exchanges are no different from the conventional e-mail usage method.)
(B) A registered user whose email address has been questioned (6) by an unregistered user accesses (7) the screen of the “user information management Web server” and leads to the “registration screen” on that screen. Is displayed in a text or a two-dimensional barcode or the like "(8), and the other party is guided (9).
(C) A user who intends to newly register accesses the “user information management Web server” screen and sets his / her password to perform use registration (10).
In contrast, the “user information management Web server” issues an identification code, displays it on the screen of the newly registered user, and notifies the identification code by e-mail.
In addition, in order to prevent multiple identification codes from being attached to one person, the mail address is used as a key to check the database, and only when the original address does not match past user data. An identification code shall be assigned.
(D) Usually, in many cases, the sender of junk mail does not match the registered address, so when the e-mail is sent (12) to the “address conversion / forwarding mail server”, the address does not match (Abnormal) is detected and no transfer is performed (13).
(E) Exceptionally, if the sender of the junk e-mail sends an e-mail from an e-mail address that matches the original registered e-mail address (14), the “address conversion / forwarding mail server” is abnormal. However, in such a case, the registered user who received the junk e-mail writes down the identification code included in the junk e-mail and then “user information” By accessing the management Web server and setting the sender's identification code to stop using (16), it is possible to prevent subsequent reception of spam mails. This is an effective method to eliminate subsequent mails when the other party who gave you an email address becomes a stalker.
(F) If it is assumed that registration cannot be requested from the other party (for example, an e-mail address used when applying for a sweepstakes), the registered user will send the other party on the “User Information Management Web Server” The character string to be recognized is registered, a new identification code is issued to the other party, and “a dedicated mail address for the other party to send to himself” is displayed.
As a result, it is possible to give different e-mail addresses to all notification destinations, and it becomes possible to identify the leaked portion when personal information leaks. By making it possible to specify this leakage, it is possible to expect the effect of suppressing leakage of email addresses.
The present invention has the above configuration.

Basic operation of "Address translation / forwarding server" Behavior when a registered user asks for an email address from another person Operation when there is a user trying to register Operation when normal spam mail (address mismatch) arrives Operation when an exceptional junk mail (address match) arrives
