Description

  The present invention relates to a technique for managing e-mail addresses registered for various service sites on the Internet.

  In various sites of service providers who provide services to users on the Internet, users often register e-mail addresses when providing services. The service provider side stores the user's email address. However, if the service provider side has insufficient security, the registered email address may be leaked to a third party.

  As countermeasures by the user in case such a leakage of the email address occurs, (1) It is possible to specify the leakage source (the registered address of the email address), and the leakage source as necessary. There are a method of requesting an appropriate measure, and (2) a method of preparing a plurality of e-mail addresses, setting usage conditions for each e-mail address in advance, and not receiving e-mails that do not satisfy the conditions. .

  In order to realize the method (1), it is only necessary to register different e-mail addresses for each registration destination and manage the registration destination and the e-mail address in association with each other. It is necessary to prepare more than one. Usually, an email address can be obtained by contracting with a provider, etc., or by performing a procedure for using an existing free email service. However, in order for an individual to obtain multiple different email addresses, these agreements and procedures can be obtained. Must be performed each time, and there is a problem that it takes time and cost to use an address.

  In addition, since the user needs to set up the mail software for each mail address, it takes time to set up the mail software to properly use multiple mail addresses, and the correspondence between those mail addresses and registration destinations. The user himself / herself has to perform the attachment, and the management of the mail address becomes complicated.

  Furthermore, according to the method (1), when spam mail arrives from a sender who does not remember due to e-mail address leakage at the registration destination, the mail is sent from the mail address that is the destination. Although the registration destination of the address can be specified, the user himself / herself also manages the mail address, so there is a problem that it is difficult to deny the possibility that the mail address has been leaked due to his own negligence or the like.

  A specific example of a system that employs the method (2) is a mail system described in Non-Patent Document 1. This mail system uses a mail address (hereinafter referred to as “user mail address” or “real mail address”) held by a user separately from service use, service provider information, etc. This is a system for generating and managing a plurality of “registration mail addresses” to be notified by a separate device. An outline of the operation in this mail system will be described with reference to FIGS.

  FIG. 1 is a center apparatus connected to a registration destination server of a user terminal and a service provider via a network, and generates a registration email address that is a mail address notified to the registration destination server as a user email address. It is a figure which shows the mail address registration operation | movement in the system registered into a registration destination server.

  First, the user notifies the center device of usage conditions including an expiration date, a registered partner, and the like and a “user mail address” that is a mail address for the user to receive mail from the center device (step 1). . The center device generates a conditional e-mail address in which the usage conditions received from the user terminal are encrypted and embedded (step 2), and issues them to the user terminal (step 3). The user registers the conditional mail address (registration mail address) as his / her mail address in the registration destination server (step 4).

  FIG. 2 is a diagram illustrating an operation until the mail reaches the user terminal when the mail is transmitted from the registration destination server to the user. When the registration destination server sends an e-mail to the conditional e-mail address (registration e-mail address), the e-mail is received by the center device that is the e-mail server of the conditional e-mail address (step 5). When the center device identifies the mail addressed to the conditional email address, the center device decrypts the user email address, the usage condition related to the conditional email address, etc. from the conditional email address (step 6), and the email satisfies the usage conditions. If the condition is satisfied, the mail received from the registration destination server is forwarded to the user mail address. If the e-mail does not satisfy the usage conditions, the e-mail is not transferred to the user terminal, and predetermined processing such as discarding or notifying an error to the registration destination server is performed (step 7).

  According to the method (2), the real mail address (user mail address) can be concealed from the registration destination, and the user mail is sent when the center device sends a mail that violates the use conditions. There is an advantage that some spam mails that block forwarding to the address can be eliminated. Also, since the real mail address information and usage conditions are encrypted and embedded in the registration mail address itself (address string itself), there is also an advantage that the center device does not need to have the corresponding information. is there.

However, when an e-mail address is leaked at the registration destination server, spam mail or the like reaches the user depending on the use conditions registered in the center apparatus. In this case, unless the user himself / herself manages the correspondence between the registration email address and the registration destination, the leakage source (registration destination) of the email address cannot be specified, and an appropriate countermeasure is required for the leakage source. Therefore, there is a problem that the user is not completely released from the management of the registration mail address corresponding to the registration destination. Further, when the registration e-mail address is leaked, as in the method (1), since the user knows the registration e-mail address, there is a problem that the possibility of the leakage from the user himself cannot be denied. .

  In addition, if an e-mail address is leaked from the service provider and, as a result, it is suspected that a spam e-mail has been received from a third party, the e-mail is received according to the contents of the received e-mail or an inquiry to the e-mail address management device. The service provider of the registered email address corresponding to the received email can be specified, and the user himself / herself can also determine the contents of the registered email address from the email address management device and the relationship between the registered email address and the provided service provider. Since it is not informed, the possibility of leakage from the user himself can be denied.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(System overview)
First, an outline of the operation of the system according to the embodiment of the present invention will be described with reference to FIGS.

  FIG. 3 is a diagram for explaining the outline of the embodiment of the present invention.

  The user uses a user terminal 92 such as a personal computer to send and receive general mail via the mail server 94 using a mail address (for example, ABC@origin.jp) that can be identified by the mail server with which the user is contracted. Yes.

  Further, since the service provider that provides the service for the user using the service providing apparatus 93 receives the provision of the user mail address from the mail address management apparatus 91, information on the service providing apparatus 93 and the registration from the user are provided. A procedure program for executing the procedure is registered in the mail address management device 91 in advance.

  When a user uses a service provided by the service providing apparatus 93, information for user registration (access destination for use registration (in the case of this example) from the service providing apparatus 93 via a network (not shown)). , The address of the mail address management device 91), the access method, the input information, etc.).

  The registration accepting unit 911 of the mail address management device 91 receives user information including the user email address from the user terminal 92 by executing a program registered in advance from the service providing device 93, and sends it to the registered address generation unit 912. Supply.

  In the registration address generation unit 912, an email address corresponding to the registration is generated as a registration email address, and the user information including the user email address is paired with the generated service provider information including the registration email address. It is recorded and held in the registration information recording unit 913.

  The registration e-mail address generated by the registration address generation unit 912 is generated so that the e-mail addressed to this address is received by the e-mail address management device 91.

  In addition, the registration information recording unit 913 records and holds the registration mail address and the address on the network of the service providing apparatus that is the transmission destination of the user information so as to be associated with each other.

  In the description of the present invention, a case where a plurality of registration e-mail addresses are generated in advance and selected from the generated e-mail addresses without being generated each time is indicated as “generated”.

  FIG. 4 is an example of data recorded and held in the registration information recording unit 913. In this embodiment, detailed information related to the user (user attribute information such as user name, user address, age, etc.) is not shown, but is recorded and held linked to the user identification information. The same applies to the detailed information of the service provider.

  When a registration e-mail address is generated and coordinated with a service provider (device, service content) and recorded and held in the registration information recording unit 913, the registration e-mail address and user information required on the service providing apparatus 93 side (Necessary information items may be received and held in advance by the mail address management device 91 from the service providing device 93, or all user-related data received from the user terminal 92 may be used as necessary user information. ) Is transmitted from the user information notification unit 914 to the service providing apparatus 93 via the network.

  The service providing apparatus 93 records and stores the received user information (including the registration e-mail address) in the user information recording unit 932 in pairs with the contents of the provided service. Information necessary for providing a service to the user, such as a user name, may be received as part of the user information from the mail address management device 91. For some user information excluding the registration mail address, You may acquire directly from the user terminal 92 via a network.

  As described above, the user who receives the service provision is registered in the service providing apparatus 93.

  The service providing apparatus 93 selects a user who meets the purpose of information transmission from the user information recording unit 932, reads out the user's mail address (registration mail address), and assembles a transmission mail (mail title, text, transmission) (E-mail address, sender information, etc.) and send it to the network.

  The sent mail is received by the mail address management device 91 (for example, as shown in the example of FIG. 4, the domain name of the registration email address is matched with the domain name of the mail address management device 91 to manage the mail address. The mail may be received by a mail server that can be read by the device 91).

  When the mail transfer unit 915 of the mail address management device 91 receives a mail having the registration mail address as a destination (transmission destination), the user mail address corresponding to the mail transmission destination address (registration mail address) is recorded as registration information. The transmission destination address (registration mail address) of the received mail read from the unit 913 is replaced with the user mail address. In addition, the identification information (management information) that can identify the email is embedded in the email, and the transfer history so that the embedded identification information, the registration email address designated as the email transmission destination, and the user email address can be mutually handled. Save in the recording unit 916.

  The mail transfer unit 915 transmits the rewritten mail (destination: user mail address) to the network when the rewriting of the mail address and the storage of the rewrite record are normally completed.

  This rewritten and transmitted mail is read out by the user terminal 92 via the mail server 94 used by the user regardless of the service provided by the service providing apparatus 93, as in the case of general mail addressed to the user. Information from the service providing device 93 is transmitted to the user.

  Even when user information is leaked from the service providing device 93 and an unauthorized acquirer of user information sends a spam mail to the user, as long as the leaked address is a registration email address, the email from the unauthorized acquirer Similarly to the above, it is transmitted to the user via the mail address management device 91.

  When the received mail is a spam mail, the user can know from which service provider the mail address has been leaked to the unauthorized acquirer as follows.

  First, the user sends a mail in a predetermined format from the user terminal 92 to the mail address management device 91 and to a predetermined procedure for an email address leak inquiry (for example, to a specific mail address of the mail address management device 91). Information including identification information given from the user mail address and the mail address management device 91 is transmitted to the mail address management device 91 by a procedure for accessing the service home page of the mail address management device 91 or the like. The transmitted information is interpreted by the registered mail address inquiry correspondence unit 917, and the identification information is uniquely given to all mails of all the users managed by the mail address management device 91 by the user mail address and the identification information. The user email address can be made unnecessary), the registration email address of the sender is identified, and the service provider associated with the registration email address for the email inquired by the user from the registration information recording unit 913 Is read. The mail address management device 91 returns the read service provider information to the user terminal 92 by a predetermined means.

  In this way, the user email address and the registration email address are associated with each other by the email address management device 91, and the registration email address is provided to the user terminal 92 (service user of the service provision device) by the service provision device 93 (service provision). Since the user e-mail address is not informed, and an individual e-mail address is assigned to each service providing apparatus or service provider or provided service, the mail that is based on the inquiry from the user Since the e-mail address management device 91 can perform association with the transmission destination (e-mail address for registration), the user can explain to the service provider that the e-mail address has not been leaked due to his own error, and the service provider E-mail address (e-mail address for registration) provided for The fact makes it possible to explain that the spam e-mail has been sent.

(Detailed system configuration)

The registration information management unit 13 registers and searches the registration information management table 151 for a registration destination ID, a registration mail address, and a real mail address (user mail address). The transfer history management unit 14 registers and searches for a mail identification ID and a registration mail address in the transfer history management table.

  The registration information management table 151 in the data recording unit 15 stores a registration mail address, a registration destination ID, and a real mail address in association with each other. FIG. 6A shows an example of the registration information management table. The transfer history management table 152 stores an ID that uniquely identifies a mail addressed to a registration e-mail (e-mail to be transferred) and a registration e-mail address in association with each other in order to respond to a registration destination inquiry from a user. FIG. 6B shows an example of the transfer history management table.

  The registration destination management table 153 stores information input from the registration destination and information generated by the mail address management server. FIG. 6C shows an example of the registration destination management table. The user registration page storage unit 154 stores the user registration page generated for each registration destination by the mail address management server in a location associated with the registration destination.

  Various page display units 161 of the external interface unit 16 have a function of displaying a registration destination registration page, a user registration page, a registration destination inquiry page, and the like. The mail transmission / reception unit 162 has a function of receiving mail addressed to a registration mail address, assigning an identification ID to the received mail, transferring to a real mail address, and the like.

  The mail address management server 1 is realized by using a computer having a communication function. Each functional unit described above is realized by mounting a program for executing the processing described in this embodiment on the computer.

  The configuration of the functional unit illustrated in FIG. 5 is an example. For example, the e-mail address management server 1 receives a registration page request including information for identifying a registration-destination service provider who registers a registration e-mail address from the user terminal, and displays a registration page corresponding to the service provider. The registration page providing unit to be transmitted to the user terminal and the user's true mail address (user mail address) transmitted from the user terminal are received, the registration mail address for the service provider is generated, and the generated registration mail is generated. An email address generation management unit that stores the address, the identification information of the service provider, and the user's true email address in association with each other, and the registration email address generated by the email address generation management unit The registration email address registration section to be registered on the service provider server of the service provider, and the registration Receiving the mail sent to the mail address, obtaining the true mail address associated with the registration mail address from the storage means, and sending the mail with the identification ID for identifying the mail Rewrite the destination address to a true email address (user email address), send it to the user email address, associate the identification ID with the registration email address, and store it in the storage means, and the identification ID A registration destination notification unit that receives information from the user terminal and transmits to the user terminal information for identifying the registration destination service provider of the registration mail address corresponding to the received identification ID may be provided. .

(System operation details)
Next, the operation of the system according to the present embodiment will be described in detail with reference to FIGS. First, a sequence at the time of registration of a service provider as a user registration destination will be described with reference to FIG. Note that the processing described in FIG. 7 is an example for accepting user registration addressed to the service provider from the user terminal by the mail address management server 1, and prior to the implementation of the service for the user, the service provider side device This is a preparatory process performed between the (server, terminal) and the mail address management server.

  When the registration destination terminal 21 transmits a display request for registration destination registration page to the various page display unit 161 (step 31), the various page display unit 161 transmits the registration destination registration page to the registration destination terminal 21 to register it. The destination terminal 21 displays a registration destination registration page (step 32). Next, the registration destination terminal 21 transmits the registration destination name and the user registration program path on the registration destination server to the mail address management server 1 (step 33). The user registration program path on the registration destination server 2 is the location of the user registration program on the registration destination server 2.

  The registration destination name and the user registration program path on the registration destination server are passed from the various page display units 161 to the registration destination management unit 12 (step 34). The registration destination management unit 12 pays out the registration destination ID, the path of the mail address generation unit 11, and the user registration page storage location, and generates a user registration page (step 35). This user registration page corresponds to the registration destination. For example, a plurality of registration page patterns are prepared and the registration destination is selected and selected in steps 32 and 33. This page can be used as a user registration page.

  The registration destination management unit 12 stores the registration destination ID, the registration destination name, the path of the mail address generation unit 11, the user registration page storage location, and the user registration program path on the registration destination server 2 in the registration destination management table 153. (Step 36). Also, the registration destination management unit 12 stores the user registration page in the user registration page storage unit 154 (step 37). The path for the mail address generation unit 11 is embedded in this user registration page.

  Subsequently, the registration destination management unit 12 notifies the user registration page storage location to the various page display units 161 (step 38), and the various page display unit 161 notifies the registration destination terminal 21 of the user registration page storage location (step 38). Step 39). The user registration page storage location notified to the registration destination terminal 21 is passed to the registration destination server 2 and used to redirect access from the user terminal 3 to the user registration page. Since the user registration page is stored for each registration destination, the user registration page storage location corresponds to information for identifying the registration destination.

  Next, a sequence at the time of registering a mail address at a registration destination will be described with reference to FIG.

  When a user registration request is transmitted from the user terminal 3 to the registration destination server 2 (step 40), the registration destination server 2 sends a redirect request to the user terminal 3 (step 41). The redirect request includes the user registration page storage location. The user terminal 3 redirects the mail address management server 1 based on the redirect request (step 42). The redirect includes a registration page request including a user registration page storage location. The various page display units 161 that have received access from the user terminal 3 obtain the user registration page corresponding to the target registration destination from the user registration page storage unit 154 (step 43). As described in step 37, the path of the mail address generating unit 11 for the registration destination is embedded in this user registration page.

  The various page display unit 161 outputs a user registration page to the user terminal 3 (step 44). In the user terminal 3, user identification information and a real mail address are input by the user and transmitted to various page display sections 161 together with the path of the mail address generation section 11 (step 45). The real mail address is sent from the various page display sections 161 to the corresponding mail address generation section 11 (step 46).

  Then, the mail address generation unit 11 sends the path of the mail address generation unit 11 to the registration destination management unit 12 (step 47), and the registration destination management unit 12 uses the path information of the mail address generation unit 11 to register the registration destination management table. By searching 153, the ID of the registration destination and the user registration program path on the registration destination server are acquired and sent to the mail address generation unit 11 (steps 48 and 49).

  The mail address generation unit 11 generates a registration email address (step 50), and transmits the registration destination ID, the generated registration email address, and the user registration program path on the registration destination server to the various page display units 161 (step 50). 51).

  As an example of a method for generating a registration e-mail address in step 50, a unique registration e-mail address is formed by concatenating a hash value of a real e-mail address, a random number, an ID indicating a registration destination, and a sequential number assigned by a server. There is a method.

  In step 52, the various page display unit 161 passes the user identification information and the registration e-mail address to the user registration program on the registration destination server 2, as well as the registration e-mail address, the registration destination ID, and the real e-mail address (user e-mail address). ) To the registration information management unit 13 (step 53), and the registration information management unit 13 stores the registration e-mail address, registration destination ID, and real e-mail address in the registration information management table 151 (step 54). In step 53, the registration date and time may be sent to the registration information management unit 13 in addition to the above information. In step 54, the registration information management unit 13 may store the registration date and time in the registration information management table 151.

  The various page display unit 161 makes a redirect request to the user terminal 3 (step 55), the user terminal 3 redirects to the registration destination server 2 (step 56), and the registration destination page from the registration destination server 2 to the user terminal 3 Is displayed (step 57). The registration destination page describes, for example, that registration has been completed.

  Next, referring to FIG. 9, the mail address management server 1 receives a mail transmitted from a registration destination (service provider) or a person who has obtained an address from the registration destination, with the registration mail address as a transmission destination. The sequence transferred to the user terminal 3 will be described.

  When a mail having a registration mail address as a transmission destination is transmitted from a terminal of a registration destination or a terminal such as an unauthorized address acquirer, the mail transmission / reception unit 162 of the mail address management server 1 receives the mail (step 58). The mail transmission / reception unit 162 sends the registration email address to the registration information management unit 13 (step 59), and the registration information management unit 13 acquires the real email address from the registration information management table 151 based on the registration email address (step 60). ) The real mail address is sent to the mail transmitting / receiving unit 162 (step 61).

  The mail transmission / reception unit 162 assigns a mail identification ID to the received mail (step 62), rewrites the mail destination address from the registration mail address to the real mail address (user mail address), and adds the mail identification ID. The sent mail is transmitted (transferred) to the user terminal 3 (step 63). Further, the mail transmission / reception unit 162 sends the added mail identification ID and the registration mail address specified as the destination of the received mail to the transfer history management unit 14 (step 64), and the transfer history management unit 14 sends the mail identification ID. The registration e-mail address is stored in the transfer history management table 152 (step 65). The information sent in step 64 may include the transfer date and time, and the transfer date and time may be stored in the transfer history management table 152 in step 65.

  Next, the sequence at the time of registration destination inquiry by the user who received the mail will be described with reference to FIG. Here, for example, when a mail from a registered sender who does not remember is received, the user determines that the mail is a mail transmitted from the mail address management server 1 because a mail identification ID is added. This determination can be automatically determined by the user terminal 3 by a program process if the mail identification ID provision rule is negotiated between the mail address management server 1 and the user terminal 3. When it is determined that the mail has been transmitted (transferred) from the mail address management server 1, the registration of the registration destination is inquired from the user terminal 3 to the mail address management apparatus 1 by the identification ID given to the received mail. I do. Upon receiving the inquiry, the mail address management server 1 determines the registration mail address designated as the destination from the transfer history management table 152, identifies the registration destination that is the registration destination of the registration mail address, and notifies the user.

  In FIG. 10, when a registration destination inquiry page display request is sent from the user terminal 3 to the various page display units 161 (step 66), the registration destination inquiry page is displayed on the user terminal 3 from the various page display units 161 (step 66). Step 67).
