Description

[0001]
BACKGROUND OF THE INVENTION
The present invention uses a relay network that connects a communication terminal of a recipient and a communication terminal of an arbitrary sender that communicates with the recipient in accordance with a receiver identifier that can uniquely identify a recipient who receives communication. Related to communication technology.
[0002]
[Prior art]
Conventionally, in a public network such as a public telephone network or the Internet, a communication terminal of a recipient and a communication terminal of an arbitrary sender are connected according to a recipient identifier that can uniquely identify the recipient. That is, when a sender designates a receiver identifier that can uniquely identify a receiver such as a telephone number or an e-mail address at the communication terminal for the relay network, the relay network receives the receiver based on the receiver identifier. And the sender's communication terminal and the receiver's communication terminal are connected to each other (note that the connection here means setting a real-time communication path between the communication terminals, mail and data from one communication terminal. It is assumed to include all meanings such as transmitting to the other communication terminal.
[0003]
The above-mentioned receiver identifier is usually given to one line or one receiver basically by a person who manages and operates a relay network (such as a telecommunications carrier or an Internet service provider). This receiver identifier is directly communicated to the other party (sender) who wants to send information such as relatives, acquaintances, and business partners, or is notified by various means such as telephone, FAX, letter, and e-mail (Patent Document 1). reference).
[0004]

[0005]
[Problems to be solved by the invention]
By the way, the above-described receiver identifier may be notified as a contact address when the receiver applies for a sweepstakes or applies for mail order, etc., and the user identifier disclosed by such receiver's own action However, it may be illegally leaked to a third party without the user's permission.
[0006]
Once the recipient identifier is known to such third parties, spam calls and spam emails for sales and solicitation frequently come in and are used for purposes other than the recipient's expectation. In many cases, the line and e-mail address became virtually unusable.
[0007]
In such a case, the receiver abandoned this receiver identifier and obtained a new receiver identifier from the person who manages and operates the relay network, but changed the contact information to the new receiver identifier. There is a problem that it takes a lot of trouble because it has to be communicated to a sender who wishes to make a plurality of outgoing calls.
[0008]
An object of the present invention is to solve such a conventional problem and prevent a recipient identifier from being used for an intended use of the recipient.
[0009]
[Means for Solving the Problems]
In the present invention, a communication system including a relay network that connects a communication terminal of a receiver and a communication terminal of a caller that transmits communication to the receiver according to a receiver identifier R that can uniquely identify a receiver that receives communication. A disclosure identifier management device that issues the disclosure identifier T by registering it in the database in association with the recipient identifier R, and restores the recipient identifier R from the disclosure identifier T using the database; The problem is solved by providing a service control device that restores a communication request designating the disclosure identifier T as a destination using the disclosure identifier management device, selects a processing method, and instructs the relay network.
[0010]
The disclosure identifier management device receives a recipient registration request specifying the recipient identifier R transmitted from the device of the recipient who requests registration of the recipient, and determines a combination of the disclosure identifier T and the recipient identifier R. A means for registering in the identifier database for disclosure (recipient registration means), an identifier S of the sender transmitted from the apparatus of the person who requests setting of communication conditions, and a condition C for permitting a communication request to the receiver of the sender A communication condition setting request for specifying the information, and registering them in the disclosure identifier database in association with the disclosure identifier T and the receiver identifier R (communication condition setting means), and disclosure from the service control device A restoration request designating the identifier T and the identifier S is received, and the receiver identifier R and the identifier corresponding to the identifier T and the identifier S are disclosed from the disclosure identifier database. Get the condition C, comprising at least a means for notifying the service control apparatus (disclosed identifier restoring means).
[0011]
Further, the service control device receives a communication request that is transmitted from the communication terminal of the caller to the relay network and designates the disclosure identifier T transferred from the relay network as a destination (communication request receiving unit) A means (determination information acquisition means) for acquiring information C0 corresponding to the sender identifier S and the condition C based on the communication request, and a disclosure identifier management apparatus by designating the disclosure identifier T and the identifier S A request for restoration to the receiver (disclosure identifier restoration request means), processing of a communication request to the recipient's communication terminal of the recipient identifier R based on the condition C received from the disclosure identifier management apparatus and the acquired information C0 And means for selecting a method and instructing the relay network (communication processing method selection means).
[0012]
Here, as a device of a person who requests registration of a recipient and a device of a person who requests setting of communication conditions, a device that discloses a disclosure identifier to a sender (disclosure identifier disclosure device) can be used. The identifier disclosure device for disclosure may be a communication terminal of the recipient.
[0013]
FIG. 1 shows the basic configuration of the present invention when a disclosure identifier disclosure apparatus is used as the apparatus of a person who requests registration of a recipient and the apparatus of a person who requests setting of communication conditions.
[0014]
In FIG. 1, 1 is a receiver's communication terminal (receiver terminal), 2 is a caller's communication terminal (caller terminal), 3 is a relay network, 4 is a disclosure identifier disclosure device, and 5 is a disclosure identifier management device. , 6 are service control devices, the receiver terminal 1 and the sender terminal 2 are subscribers of the relay network 3, and the disclosure identifier management device 5 can communicate with the disclosure identifier disclosure device 4 and the service control device 6. The service control device 6 is connected so as to be communicable with the relay network 4.
[0015]
The disclosure identifier management device 5 includes a disclosure identifier database (DB) 51, a recipient registration unit 52, a communication condition setting unit 53, a disclosure identifier restoring unit 54, and a disclosure identifier T. 4, and the service control device 6 includes a communication request receiving unit 61, a determination information obtaining unit 62, a disclosure identifier restoration request unit 63, and a request processing method selection unit. 64.
[0016]
The disclosure identifier DB 51 includes at least one sender identifier S (s1, s2,...) And communication condition C (c11) for the combination of the disclosure identifier T (a) and the receiver identifier R (r). , C12,..., C21, c22,...) Are registered as many as the number of disclosure identifiers T (or recipient identifiers R).
[0017]
The identifier S of the sender of the disclosure destination includes a group ID and the like.
[0018]
In the above configuration, the disclosure identifier management device 5 receives a recipient registration request specifying the recipient identifier R of the recipient terminal 1 transmitted from the disclosure identifier disclosure device 4. When the request is received, the recipient registration means 52 of the disclosure identifier management device 5 checks whether or not there is an entry including the recipient identifier R in the disclosure identifier DB 51. For example, an unused disclosure identifier T is paid out, and an entry combining the disclosure identifier T and the recipient identifier R is additionally registered in the disclosure identifier DB 51.
[0019]
Next, the disclosure identifier management device 5 specifies the identifier S of the sender terminal 2 transmitted from the disclosure identifier disclosure device 4 and the communication condition C permitting the communication request of the sender terminal 2 to the receiver terminal 1. Received the received communication condition setting request. When the request is received, the communication condition setting unit 53 of the disclosure identifier management device 5 registers the identifier S and the communication condition C in the entry including the disclosure identifier T and the receiver identifier R in the disclosure identifier DB 51, and discloses the disclosure. The disclosure identifier notifying unit 54 notifies the disclosure identifier disclosure device 4 of the disclosure identifier T.
[0020]
Thereafter, the disclosure identifier T is notified (disclosed) from the disclosure identifier disclosure device 4 to the caller terminal 2. As a specific method at this time, the disclosure identifier disclosure device 4 is managed. The person may directly communicate with the caller, or may be by telephone, e-mail, FAX, mail or the like.
[0021]
On the other hand, the caller terminal 2 that has received the disclosure identifier T designates this as a destination and requests communication to the relay network 3. When receiving a communication request designating the disclosure identifier T as a destination, the relay network 3 transfers the communication request to the service control device 6.
[0022]
When the communication request receiving unit 61 of the service control device 6 receives the communication request designating the disclosure identifier T as the destination, the communication request receiving unit 61 activates the determination information acquisition unit 62 and sends the disclosure identifier T to the disclosure identifier restoration request unit 63.
[0023]
The determination information acquisition means 62 of the service control device 6 acquires information C0 corresponding to the caller identifier S and the condition C based on the communication request, and sends the identifier S to the disclosure identifier restoration request means 63. C0 is sent to the request processing selection means 64. Further, the disclosure identifier restoration requesting unit 63 designates the disclosure identifier T and the identifier S and requests the disclosure identifier management device 5 to restore the disclosure identifier T.
[0024]
When the disclosure identifier restoring unit 55 of the disclosure identifier management device 5 receives the restoration request for the disclosure identifier T, the disclosure identifier restoring unit 55 searches the disclosure identifier DB 51 for an entry including the disclosure identifier T and the identifier S, and The identifier R and the condition C are acquired and returned to the service control device 6. If there is no entry including the disclosure identifier T and the identifier S, the fact is notified.
[0025]
The request processing method selection means 64 that has received the identifier R and the condition C via the disclosure identifier restoration request means 63 of the service control device 6 communicates the identifier R with the receiver terminal 1 based on the condition C and the information C0. The request processing method is selected and the relay network 3 is instructed. At this time, if the instruction permits a communication request, the relay network 3 establishes communication with the receiver terminal 1 using the identifier R.
[0026]
Here, by including information for identifying the caller or caller terminal and information for limiting the usable period in the condition C, the use condition of the disclosure identifier T can be limited. As an example of information which limits a caller or a caller terminal, there is an identifier of a caller or a caller terminal and a hash value calculated from this identifier. Also, examples of information that limits the usable period include the expiration date of the disclosure identifier T, the effective time zone (night prohibition, etc.), and the like.
[0027]
In this case, as described above, the request processing method selection unit 64 of the service control device 63 uses the condition C obtained by restoring the disclosure identifier T and the information C0 obtained by the determination information obtaining unit 62, that is, from the relay network 3. It is possible to determine whether to permit or reject the communication request by comparing and collating the identifier S of the caller transferred at the same time as the communication request and the date and time when the request is received.
[0028]
Further, the effective use count of the disclosure identifier T may be used as the condition C. However, in this case, the control device is provided with a communication history recording means, and when a communication request is received, the communication history indicating the number of times the sender of the identifier S has sent to the receiver of the identifier R is scanned, It is necessary to compare the scanning result with the condition C, select a communication request processing method according to the result, and execute a process of updating the communication history when receiving the communication request.
[0029]
The condition C described above can be classified into the identifier S for each sender as a disclosure destination and the receiver identifier R as a unit. In the former case, the communication condition setting means together with the identifier S is considered. In the latter case, it is registered by the receiver registration means together with the receiver identifier R as will be described later.
[0030]
It is also possible to reject a communication request from an unauthorized caller who has not received the disclosure identifier.
[0031]
FIG. 2 shows the basic configuration of a communication system according to the method of the present invention. In FIG. 2, 65 is an unauthorized caller list in which identifiers S of callers who made unauthorized calls are registered, and 66 is A function of searching the unauthorized caller list 65 by the caller identifier S acquired by the determination information acquiring unit 62, and rejecting a communication request when the caller identifier S is registered in the unauthorized caller list 65. Is added to the disclosure identifier restoration request means, and 67 is based on the disclosure identifier T in the communication request, and determines whether or not the communication request is illegal. Is a request processing selection means to which a function for registering the information in the unauthorized caller list 65 is added. Other configurations are the same as those in FIG.
[0032]
In the above configuration, when the disclosure identifier restoration request unit 66 of the service control device 6 receives the disclosure identifier T from the communication request reception unit 61, the unauthorized caller list 65 with the caller identifier S acquired by the determination information acquisition unit 62 is obtained. If the sender's identifier S is registered, the communication request is rejected. If not registered in the unauthorized sender list 65, the disclosure identifier management device 5 is requested to restore the disclosure identifier T as described above.
[0033]
Further, the request processing selection unit 67 determines that the communication request is invalid, for example, when it is notified that there is no entry including the disclosure identifier T and the identifier S in the disclosure identifier DB 51 as a result of the restoration request. If determined, the identifier S is registered in the unauthorized caller list 65.
[0034]
In the system described above, one disclosure identifier T is shared by a plurality of senders, but there are cases where it is desired to use a different one for each sender. In this case, there is simply a method of paying out a different disclosure identifier T for each sender and registering it in the disclosure identifier DB together with the receiver identifier R and the sender identifier S, but it is proportional to the number of senders. There is a problem that the number of entries is large, that is, the DB size becomes large.
[0035]
In the present invention, N (N is an integer of 2 or more) temporary disclosure identifiers H are paid out to one receiver, registered in the database, and one of them is disclosed to the sender as a disclosure identifier T. This solves the problem. FIG. 3 shows the basic configuration of the system of the present invention corresponding to the method described above.
[0036]
In FIG. 3, the disclosure identifier management device 5 includes a disclosure identifier notification unit 54, a disclosure identifier database (DB) 56, a recipient registration unit 57, a disclosure identifier selection unit 58, and a restoration unit 59. The service control device 6 includes a communication request receiving unit 61, a request processing method selecting unit 64, a determination information obtaining unit 68, and a disclosure identifier restoration request unit 69. Other configurations are the same as those in FIG.
[0037]
The disclosure identifier DB 56 includes N temporary disclosure identifiers H (a1, a2,...), Receiver identifiers R (r), and communication conditions C (c11, c12,..., C21, c22,...). Are registered for the number of provisional disclosure identifiers H (or recipient identifiers R).
[0038]
The receiver registration means 57 receives a receiver registration request specifying a receiver identifier R and a condition C for granting a communication request transmitted from the apparatus of the person who requests registration of the receiver. The identifier H is paid out, and the combination of the N temporary disclosure identifiers H, the recipient identifier R, and the condition C is registered in the disclosure identifier database 56. Disclosure identifier selection means 58 selects one of the N temporary disclosure identifiers H as a disclosure identifier T. The restoration unit 59 receives a restoration request designating the disclosure identifier T from the service control device 6, and receives recipients corresponding to N temporary disclosure identifiers H including the disclosure identifier T from the disclosure identifier database 56. The identifier R and the condition C are acquired and notified to the service control device 6.
[0039]
The determination information acquisition unit 68 acquires information C0 corresponding to the condition C based on the communication request. The disclosure identifier restoration request unit 69 specifies the disclosure identifier T and requests the disclosure identifier management apparatus 5 to restore.
[0040]
In the above configuration, the disclosure identifier management device 5 receives the recipient registration request specifying the recipient identifier R and the communication condition C of the recipient terminal 1 transmitted from the disclosure identifier disclosure device 4. When the request is received, the recipient registration unit 57 of the disclosure identifier management device 5 checks whether or not there is an entry including the recipient identifier R in the disclosure identifier DB 56. If there is, the communication condition C is included in the entry. If not, unused N temporary disclosure identifiers H are paid out, and an entry combining the N temporary disclosure identifiers H, the identifier R, and the communication condition C is additionally registered in the disclosure identifier DB 56. To do.
[0041]
Next, the disclosure identifier selection means 58 of the disclosure identifier management device 5 selects one of the N temporary disclosure identifiers H, for example, at random, and uses the selected identifier as a disclosure identifier T. The information is sent to the disclosure identifier notifying unit 54, and the disclosure identifier notifying unit 54 notifies the disclosure identifier disclosing device 4 of this. Thereafter, the disclosure identifier T is notified (disclosed) from the disclosure identifier disclosure device 4 to the sender terminal 2 in the same manner as described above.
[0042]
On the other hand, the disclosure destination terminal 2 that has received the disclosure identifier T designates this as a destination and requests communication to the relay network 3. When receiving a communication request designating the disclosure identifier T as a destination, the relay network 3 transfers the communication request to the service control device 6.
[0043]
When receiving the communication request specifying the disclosure identifier T as the destination, the communication request receiving unit 61 of the service control device 6 activates the determination information acquisition unit 68 and sends the disclosure identifier T to the disclosure identifier restoration request unit 63.
[0044]
The determination information acquisition means 68 of the service control device 6 acquires information C0 corresponding to the condition C based on the communication request and sends it to the request processing selection means 64. Also, the disclosure identifier restoration request unit 69 specifies the disclosure identifier T and requests the disclosure identifier management device 5 to restore the disclosure identifier T.
[0045]
When the disclosure identifier restoring unit 59 of the disclosure identifier managing apparatus 5 receives the restoration request for the disclosure identifier T, the disclosure identifier restoring unit 59 includes N temporary disclosure identifiers H to which the disclosure identifier T belongs from the disclosure identifier DB 56. The entry is searched, the identifier R and the condition C in the entry are acquired, and returned to the service control device 6. If there is no entry including N temporary disclosure identifiers H to which the disclosure identifier T belongs, the fact is notified.
[0046]
The request processing method selection means 64 that has received the identifier R and condition C via the disclosure identifier restoration request means 69 of the service control device 6 communicates the identifier R with the receiver terminal 1 based on the condition C and information C0. The request processing method is selected and the relay network 3 is instructed. At this time, if the instruction permits a communication request, the relay network 3 establishes communication with the receiver terminal 1 using the identifier R.
[0047]
When one of the N temporary disclosure identifiers H described above is selected by the disclosure identifier selection means 58 of the disclosure identifier management device 5, the second condition C2 designated by the disclosure identifier disclosure device 4 or the like is selected. Can be performed by using the function F having the argument as a parameter.
[0048]
In this case, the restoration means 59 of the disclosure identifier management apparatus 5 includes N receiver identifiers R and conditions C corresponding to the N temporary disclosure identifiers H to which the disclosure identifier T belongs, and the N identifiers including the disclosure identifier T. The temporary disclosure identifier H is notified to the service control device 6, and the determination information acquisition means 68 of the service control device 6 acquires information C 02 corresponding to the second condition C 2 together with information C 0 corresponding to the condition C, and requests processing In the method selection means 64, one of N temporary disclosure identifiers H is selected using the function F having the information C02 as an argument, and whether or not the received disclosure identifier T matches with the received information. Select a communication request processing method for the communication terminal of the receiver of the receiver identifier R based on the determination result or one or both of the condition C and the information C0, and relay It can be instructed to.
[0049]
At this time, if the identifier S of the sender of the disclosure destination is used as the condition C2 and the identifier of the sender obtained at the time of receiving the communication request is used as the information C02, the transmission requesting communication with the sender who has received the disclosure identifier is disclosed. The identity with the person can be verified.
[0050]
In this system, the disclosure identifier T may be selected from the N provisional disclosure identifiers H described above by the disclosure identifier disclosure apparatus. FIG. 4 shows the basic configuration of the system of the present invention corresponding to the method described above.
[0051]
In FIG. 4, the disclosure identifier disclosure device 4 includes a disclosure identifier selection unit 41, and the disclosure identifier management device 5 includes a disclosure identifier database (DB) 56, a recipient registration unit 57, and a restoration unit 59. The service control device 6 includes a communication request receiving unit 61, a request processing method selection unit 64, a determination information acquisition unit 68, and a disclosure identifier restoration request unit 69. Other configurations are the same as those in FIG.
[0052]
Disclosure identifier selection means 41 selects one of N temporary disclosure identifiers H received from disclosure identifier management device 5 as disclosure identifier T. The information transfer means 510 transmits N temporary disclosure identifiers H to the disclosure identifier disclosure device.
[0053]
In the above configuration, the disclosure identifier management device 5 receives the recipient registration request specifying the recipient identifier R and the communication condition C of the recipient terminal 1 transmitted from the disclosure identifier disclosure device 4. When the request is received, the recipient registration unit 57 of the disclosure identifier management device 5 checks whether or not there is an entry including the recipient identifier R in the disclosure identifier DB 56. If there is, the communication condition C is included in the entry. If not, unused N temporary disclosure identifiers H are paid out, and an entry combining the N temporary disclosure identifiers H, the identifier R, and the communication condition C is additionally registered in the disclosure identifier DB 56. To do.
[0054]
Next, the information transfer means 510 of the disclosure identifier management device 5 transmits the N temporary disclosure identifiers H to the disclosure identifier disclosure device 4.
[0055]
The disclosure identifier selection means 41 of the disclosure identifier disclosure device 4 selects one of the N temporary disclosure identifiers H, for example, at random, and sets the selected identifier as the disclosure identifier T. Thereafter, the disclosure identifier T is notified (disclosed) from the disclosure identifier disclosure device 4 to the caller terminal 2 in the same manner as described above, and the subsequent operations are the same as those in FIG.
[0056]
At this time, in the information transfer means 510 of the disclosure identifier management device 5, either the algorithm of the function F or the parameters constituting the algorithm or both of them together with the N temporary disclosure identifiers H are disclosed identifier disclosure device. 4 for disclosure, and the selector 41 of the disclosure identifier disclosure apparatus 4 uses one of the N provisional disclosure identifiers H as the argument for the second condition C2 as an argument. You may make it select as T.
[0057]
3 and 4 can also reject a communication request from an unauthorized caller by using an unauthorized caller list as shown in the system of FIG. However, in that case, it is necessary to acquire the sender's identifier S together with the information C0 (or C02 in addition thereto) in the determination information acquisition means.
[0058]
Furthermore, in the system of FIGS. 1 to 4, the service control device 6 notifies the acquired condition C and information C0 to the receiver terminal 1 of the receiver identifier R, and the receiver terminal 1 receives the condition C and information. A communication request processing method may be selected based on C0 and instructed to the relay network.
[0059]
Further, in this system, when disclosing the disclosure identifier T from the disclosure identifier disclosure device to the caller, the disclosure is performed after performing a conversion process depending on the caller identifier S that cannot be reversely converted by the caller, When the service control device receives the disclosure identifier T from the caller's communication terminal via the relay network, the service control device performs a reverse conversion process of conversion depending on the caller identifier S which cannot be reversely converted by the caller. It may be made. Further, as the above-described reversible conversion process, an encryption / decryption process using a key corresponding to the sender's identifier S may be performed.
[0060]
Also, disclosure (notification) of the disclosure identifier T to the sender is performed by using the service control device to send a communication request for notification of the disclosure identifier T specifying the sender identifier S from the receiver terminal device as the destination. This can also be done by transferring the identifier of the sender as the disclosure identifier T. FIG. 5 shows the basic configuration of the system of the present invention corresponding to the method described above.
[0061]
In FIG. 5, the disclosure identifier management device 5 includes a disclosure identifier database (DB) 51 and a disclosure identifier acquisition unit 511. The service control device 6 includes a communication request reception unit 610, a transmission source information acquisition unit. 611, disclosure identifier acquisition request means 612, and communication request transmission means 613. Other configurations are the same as those in FIG. 1, but the configuration relating to the generation and restoration of the disclosure identifier is omitted.
[0062]
Disclosure identifier acquisition means 511 receives a disclosure identifier T acquisition request specifying the identifier S and identifier R from the service control device 6, and discloses the disclosure identifier corresponding to the identifier S and identifier R from the disclosure identifier database. T is acquired and notified to the service control apparatus.
[0063]
The communication request receiving unit 610 receives a communication request that is transmitted from the communication terminal of the receiver to the relay network, and that is transmitted from the relay network and specifies the identifier S of the sender for notification of the disclosure identifier T as a destination. To do. The sender information acquisition unit 611 acquires a sender identifier, that is, a receiver identifier R based on the communication request. The disclosure identifier acquisition request unit 612 designates the identifier S and the identifier R and requests the disclosure identifier management apparatus to acquire the disclosure identifier T. The communication request transmission means 613 uses the disclosure identifier T as a disclosure identifier T received from the disclosure identifier management device 5 for the communication request specifying the sender identifier S for the disclosure identifier T notification as the destination. Send to the relay network.
[0064]
In the above configuration, when the receiver terminal 1 designates the identifier S of the caller terminal 2 as a destination and requests communication to the relay network 3, the relay network 3 transfers this to the service control device 6.
[0065]
When the communication request receiving means 610 of the service control device 6 receives the communication request for notification of the disclosure identifier T that designates the sender identifier S as the destination, the communication request receiving means 610 activates the sender information acquisition means 611 and uses the identifier S as the disclosure identifier. The data is sent to the acquisition request unit 612.
[0066]
The source information acquisition unit 611 of the service control device 6 acquires the identifier R of the recipient based on the communication request and sends it to the disclosure identifier acquisition request unit 612. The disclosure identifier acquisition request unit 612 requests the disclosure identifier management apparatus 5 to acquire the disclosure identifier T by specifying the identifier S and the identifier R.
[0067]
When the disclosure identifier acquisition unit 511 of the disclosure identifier management device 5 receives the acquisition request for the disclosure identifier T, the disclosure identifier acquisition unit 511 searches the disclosure identifier DB 51 for an entry including the identifier S and the identifier R, and discloses the disclosure in the entry. The service identifier T is acquired and returned to the service control device 6. If there is no entry including the identifier S and the identifier R, the fact is notified.
[0068]
The communication request transmitting unit 613 that has acquired the disclosure identifier T via the disclosure identifier acquisition request unit 612 of the service control device 6 includes a communication request in which the identifier S of the sender for notification of the disclosure identifier T is specified as a destination. Is transmitted to the relay network 3 as the disclosure identifier T.
[0069]
The relay network 3 transfers the communication request to the caller terminal 2, and the caller terminal 2 can acquire the disclosure identifier T of the receiver terminal 1 from the communication request.
[0070]
3 and 4 can also notify the sender terminal of the identifier for disclosure as shown in the system of FIG. However, in that case, N temporary disclosure identifiers H are acquired based only on the identifier R of the recipient, and one of the N temporary disclosure identifiers H is obtained by the disclosure identifier acquisition unit or the communication request transmission unit. You need to choose one.
[0071]
