Description

  The present invention relates to an impersonation telephone prevention system, an authentication apparatus, and an authentication apparatus program, and more particularly to an impersonation telephone prevention system, an authentication apparatus, and an authentication apparatus that can effectively prevent an impersonation telephone call without impairing the convenience of the telephone. It is about the program.

  In recent years, there has been a problem of so-called impersonation calls, in which fake money and personal information are tricked by calling the general public by fake a famous company or public institution, and making the other party trust. In telephone communication, since it is difficult for the receiver side to determine whether or not the sender is a legitimate person, such impersonation acts prevail.

  In order to prevent this spoofing phone call, it may be possible to use a “phone book function” of a fixed phone or a mobile phone (for example, see Patent Document 1 and Patent Document 2). This phone book function registers the telephone number and name (or company name) of the speaker on the receiver side, so that the receiver can be notified of who the speaker is when receiving a call. It is a function.

  However, as mobile phones become widespread as in recent years, there are many cases where calls are made to customers using not only fixed telephones installed in companies but also mobile phones owned by employees. The update load of the phone book function will increase. In addition, when an employee calls a customer using a public telephone or the like, the telephone directory function is meaningless. Thus, if the telephone directory function does not function sufficiently, the result is that the above-mentioned spoofing telephone is permitted.

  For this reason, a technique has been proposed in which a sender is authenticated by a device or facility provided on a network that relays telephone communications. For example, in Patent Document 3, a speaker is authenticated by using biometric information on an authentication database connected to an exchange that relays telephone communication, and a call service is provided to a speaker who has succeeded in authentication. Techniques to provide are disclosed.

Japanese Patent Laid-Open No. 2005-184076 JP 2002-374347 A JP 2002-354120 A

  However, the technique disclosed in Patent Document 3 is a technique for determining whether or not a call service is provided to a talker by authenticating the talker individually, and prevents spoofing of the talker. It is not a technology. Surely, if it is permitted to make a call only to a sender who has been successfully authenticated, the spoofing call itself will not occur. However, it is difficult to authenticate all the senders, and if it is impossible to make a call unless the authentication is passed, the convenience of the telephone is impaired.

  For these reasons, a major issue is how to implement an impersonation telephone prevention system that can effectively prevent spoofing calls without compromising the convenience of the telephone and an authentication device used in the impersonation telephone prevention system. ing.

  The present invention has been made to solve the above-described problems caused by the prior art, and it is possible to effectively prevent an impersonation call without impairing the convenience of the telephone, an impersonation telephone prevention system, an authentication apparatus, and an authentication. An object is to provide a device program.

  In order to solve the above-described problems and achieve the object, the present invention prevents an impersonation call by the transmitting telephone device by using an authentication device provided between the transmitting telephone device and the receiving telephone device. An impersonation telephone prevention system, wherein the authentication device includes a speaker information storage means for storing personal authentication information and attribute information about a speaker who uses the transmitter telephone device; Speaker authentication means for authenticating the speaker by comparing the input authentication information input to the transmitter device with the personal authentication information stored in the speaker information storage means, and the speaker Characterized in that it comprises speaker information notification means for notifying the receiving side telephone device of the attribute information about the speaker on condition that the authentication means has succeeded in authenticating the speaker. To do.

  Also, in the present invention according to the above invention, when the speaker authentication means receives an authentication request including the input authentication information from the transmitter telephone device, the input authentication information is transmitted to the speaker. The speaker is authenticated by comparing with the personal authentication information stored in the information storage means.

  Further, in the present invention according to the above-mentioned invention, if the sender authentication unit receives an authentication request from the receiver telephone device, the input authentication information is acquired from the transmitter telephone device, and the input authentication is performed. The speaker is authenticated by comparing information with the personal authentication information stored in the speaker information storage means.

  In addition, the present invention is an authentication device that is used in an impersonation telephone prevention system for preventing an impersonation telephone call by a transmission side telephone device and is provided between the transmission side telephone device and the reception side telephone device. Speaker information storage means for storing personal authentication information and attribute information about a talker using the talker telephone device, and input authentication information input by the talker to the talker phone device. A speaker authenticating unit that authenticates the speaker by comparing with the personal authentication information stored in the speaker information storing unit, and a condition that the speaker authenticating unit has succeeded in authenticating the speaker. And a sender information notifying unit for notifying the attribute information about the sender to the receiving telephone device.

  In addition, the present invention is an authentication apparatus used in an impersonation telephone prevention system for preventing an impersonation telephone call by a transmitting side telephone apparatus and mounted on an authentication apparatus provided between the transmitting side telephone apparatus and the receiving side telephone apparatus. A speaker information storage procedure for storing personal authentication information and attribute information about a speaker who uses the transmitter telephone device in a storage unit; and A speaker authentication procedure for authenticating the speaker by comparing the input authentication information input to the apparatus with the personal authentication information stored in the storage unit by the speaker information storage procedure; A computer for sending a speaker information notification procedure for notifying the receiving telephone device of the attribute information about the speaker on the condition that the authentication procedure succeeds in authenticating the speaker; Characterized in that to execute.

  According to the present invention, personal authentication information and attribute information about a speaker who uses a transmitter telephone device are stored, and personal authentication information stored in advance is input authentication information input to the transmitter telephone device by the speaker. The sender is authenticated by comparing with the information, and the attribute information about the sender is notified to the receiving telephone device on the condition that the authentication of the sender is successful. By authenticating an individual using personal authentication information such as biometric information, it is possible to prove the legitimacy of the sender, thereby effectively preventing spoofing calls. In addition, since the authentication timing of the sender is not limited at the time of calling, there is an effect that the convenience of the telephone is not impaired.

  Also, according to the present invention, when an authentication request including input authentication information is received from the transmitting telephone device, the sender is authenticated by comparing the input authentication information with the personal authentication information stored in advance. With this configuration, by performing authentication according to a request from the sender, it is possible to prevent spoofing calls without imposing a burden on the receiver.

  Further, according to the present invention, if an authentication request is received from the receiving telephone device, the input authentication information is acquired from the transmitting telephone device, and the acquired input authentication information is compared with the personal authentication information stored in advance. Since the configuration is such that the speaker is authenticated, the authentication of the speaker can be performed flexibly by authenticating the speaker at the judgment of the receiver. In other words, since it is not necessary to perform the authentication process for each call, it is possible to prevent spoofing without impairing the convenience of the call.

  Exemplary embodiments of a spoofing telephone call prevention system according to the present invention will be explained below in detail with reference to the accompanying drawings. In the following, an impersonation telephone prevention system including an authentication device provided on a network, a transmitting telephone device used by a speaker, and a receiving telephone device used by a receiver will be described. However, since the transmitting side telephone device and the receiving side telephone device can be configured by a commercially available telephone device (for example, a mobile phone), it is also possible to configure a spoofed telephone prevention system that is composed only of an authentication device.

  First, the outline of the spoofing phone call prevention system according to this embodiment will be described with reference to FIG. FIG. 1 is a diagram showing an overview of a spoofing phone call prevention system according to the present embodiment. As shown in the figure, the spoofing phone call prevention system according to the present embodiment includes an authentication device 10, a transmission side telephone device 20, and a reception side telephone device 30 provided on a network.

  The authentication device 10 is a device provided in a facility (for example, a certificate authority) for the purpose of authenticating a caller, and this certificate authority is between the transmitter telephone device 10 and the receiver telephone device 20. It is assumed that the facility is provided separately from the relay station that relays the call. In the following, a case where a company using a spoofing phone call prevention system applies for registration of information regarding its employees to the certificate authority, and the certificate authority registers the registered information in the authentication apparatus 10 will be described.

  As illustrated in FIG. 1, the authentication device 10 includes an authentication DB (database) that manages information applied for by a company. This authentication DB is a database that manages personal authentication information for authenticating individual employees (for example, biometric information such as fingerprints, voiceprints, and face images) and information that associates employee attribute information. The employee attribute information includes, for example, name, company name, department, and the like.

  Here, it is assumed that “Mr. XX” registered in the authentication DB makes a phone call to the customer using the transmission side telephone device 20. In this case, “Mr. XX” inputs authentication information such as a fingerprint to the transmitting side telephone device 20 (see (1) in FIG. 1). Then, when a call is made to a customer who uses the receiver side telephone device 30, the authentication information input to the transmitter side telephone device 20 becomes the transmitter side number (for example, the telephone number of the transmitter side telephone device 20). ) And the receiving side number (for example, the telephone number of the receiving side telephone device 30) are transmitted to the authentication device 10 (see (2) in FIG. 1).

  Note that the transmission timing of the authentication information to the authentication device 10 may be the timing at which the transmitting telephone device 20 makes a call to the receiving telephone device 30 or between the transmitting telephone device 20 and the receiving telephone device 30. It may be after the call is established. Further, it may be the timing when the authentication information transmission request is received from the telephone device 30 on the receiving side.

  Subsequently, the authentication device 10 that has received the authentication information from the transmitting side telephone device 20 executes an authentication process of “Mr. XX” by searching the authentication DB using the received authentication information as a key (FIG. 1). (See (3)). If the authentication information received from the transmitting telephone device 20 matches the personal authentication information on the authentication DB (see the personal authentication information “A” in FIG. 1), it is assumed that the authentication has succeeded, “Mr. Attribute information (name, company name and department) is transmitted to the receiving telephone device 30 (see (4) in FIG. 1). Subsequently, the receiving telephone device 30 displays the attribute information received from the authentication device 10 on a display or the like (see (5) in FIG. 1).

  As described above, in the spoofing telephone prevention system according to the present embodiment, personal authentication information and attribute information about employees registered for each company are managed on the authentication DB, and the authentication device 10 receives an authentication request. In addition, the authentication information received from the transmitting telephone device 20 is checked using the authentication DB, and the authentication result is transmitted to the receiving telephone device 30. That is, by authenticating the individual speaker using personal authentication information such as biometric information, it is possible to prove the legitimacy of the speaker, so that spoofing can be effectively prevented. Further, since the authentication timing of the sender is not limited at the time of making a call, the convenience of the telephone is not impaired.

  Next, the configuration of the spoofing phone call prevention system 100 according to the present embodiment will be described with reference to FIG. FIG. 2 is a block diagram illustrating a configuration of the spoofing phone call prevention system 100 according to the present embodiment.
