FIG. 2 is a diagram illustrating an example of user information data stored in the user information storage unit 101. The user information includes information such as a user ID, a telephone number, a name, an address, and age. The user ID is identification information for identifying the user. The telephone number, name, address, and age are the corresponding user's telephone number, name, address, and age. Such user information is input and stored by, for example, a web service provided by a user information registration unit 103 described later.

  The voiceprint information storage unit 102 stores first voiceprint information based on a predetermined person's voice in advance. FIG. 3 is a diagram illustrating a data example of registration information stored in the voiceprint information storage unit 102. In the registration information, information such as the partner user ID, the relationship, the address, the registration date, voice information, and voiceprint information is stored in association with the user ID. The user ID is identification information for identifying a user who uses the service according to the present embodiment. The information server device 100 performs voiceprint information collation processing when a call is made to the user. The counterpart user ID is a user ID of a person such as a relative who has been determined in advance that there is a possibility of making a call to the user of the corresponding user ID.

  The relationship included in the registration information is a relationship of the partner user ID viewed from the user ID. The registration date / time is the date / time when the voice information is registered. The information server device 100 compares the registration date and time with the current date and time, and if the elapsed time from the registration date and time to the current date and time exceeds a certain period, the registered information is old and is updated. A warning message for prompting may be transmitted to the communication destination terminal 20. The voice information is voice data of the partner user indicated by the partner user ID. For example, "Hello", "Hello", "Good evening", "Yes", "Yes", "grandpa", "Grandma" words uttered an opponent user, such as stores. The audio information is, for example, a general audio file such as wav or mp3. The voiceprint information is a three-dimensional histogram generated by combining the voice quality of the corresponding voice information voice information and the intonation change for reading the sentence. For example, only frequencies close to human utterances are recorded from recorded voice information, and high voice frequency bands, such as strange voices, extremely low voice frequency bands, and frequency bands that cannot be heard by human ears are voiceprint information. Not subject to

  The user information registration unit 103 accepts registration of user information and user voice from the communication terminal 30. For example, the communication terminal 30 that is a computer device such as a PC (personal computer) having a browser function or the like is a telephone terminal that provides a web screen for registering voice and receives the user's voice. An IVR guidance is transmitted to the communication terminal 30 to receive the user's voice. The user information registration unit 103 stores the received voice information in the voiceprint information storage unit 102. Also, the user information registration unit 103 stores voice information in the voiceprint information storage unit 102 in association with the user's name, address, and the like.

The voice receiving unit 104 receives voice of telephone communication performed between the communication source terminal and the communication destination terminal via the network.
The voiceprint information generation unit 105 generates second voiceprint information based on the voice received by the voice reception unit 104. The voiceprint information generation unit 105 generates voiceprint information based on the voice information of relatives and the like stored in the voiceprint information storage unit 102 and stores the voiceprint information in the voiceprint information storage unit 102. Here, the process of generating the voiceprint information based on the voice information stored in the voiceprint information storage unit 102 may be performed in real time every time the voiceprint information is stored in the voiceprint information storage unit 102. May be performed in response to a request from the user, or may be performed at regular intervals, or may be performed, for example, by batch processing at night when business processing is low.

  The determination unit 106 compares the first voice print information stored in the voice print information storage unit 102 with the second voice print information generated by the voice print information generation unit 105, and the matching rate is determined in advance. It is determined whether or not the threshold value is exceeded. If the determination unit 106 determines that the matching rate between the first voiceprint information and the second voiceprint information exceeds a predetermined threshold, the person who made the call is stored in advance. If it can be estimated that the relatives are the same person and the matching rate does not exceed a predetermined threshold, the person who made the call and the stored relatives are the same person Rather, it can be estimated that there is a possibility of wire fraud. As the threshold value, an appropriate threshold value is set such that it can be determined whether or not the person who made the call and the relatives stored in advance are the same person, and is stored in advance in the storage area of the determination unit 106.

  The warning unit 107 has a predetermined match rate between the first voiceprint information stored in the voiceprint information storage unit 102 and the second voiceprint information generated by the voiceprint information generation unit 105 by the determination unit 106. When it is determined that the threshold value is not exceeded, a warning is output to a predetermined destination because there is a possibility of telephone fraud for transfer fraud. The predetermined destination may be, for example, the communication destination terminal 20, the communication terminal 30 of a relative of the user of the predetermined communication destination terminal 20, or the like, a public organization such as a local government, the police, or the like. Here, the warning may be, for example, a predetermined warning sound may be transmitted to the communication destination terminal 20, or a warning text is included for the communication terminal 30 of the user relative to the communication destination terminal 20. E-mail may be sent. You may make it transmit the communication position map image mentioned later as a warning. In addition, when telephone communication with the possibility of wire fraud is performed a plurality of times in a certain communication area, a warning may be transmitted to the local government in the area.

  In the fixed telephone position information storage unit 108, the telephone number of the fixed telephone and the position information (latitude, longitude) indicating the installation position of the telephone terminal that performs communication using the telephone number are stored in association with each other. FIG. 4 is a diagram showing a data example of fixed telephone position information stored in the fixed telephone position information storage unit 108. In the fixed telephone position information, fixed telephone number, address, latitude, and longitude information are associated with each other. The address indicates the address where the telephone terminal with the corresponding fixed telephone number is installed. Latitude and longitude indicate the latitude and longitude of the corresponding address. Here, the latitude and longitude information may specifically be a value of the TOKYO geodetic system or a value of the WGS geodetic system, but the geodetic system corresponding to the map image stored in the map image storage unit 112. It shall be the value of.

  In the base station position information storage unit 109, a base station that communicates with a mobile phone terminal in a mobile phone communication network and position information (latitude, longitude) indicating the installation position of the base station are stored in advance in association with each other. The For example, when the communication source terminal 10 or the communication destination terminal 20 is a mobile phone terminal that performs communication via a mobile phone communication network, the communication position cannot be specified from a telephone number like a fixed phone. Here, the mobile phone terminal generally communicates with about three base stations. For example, FIG. 5 is a diagram illustrating the base station A, the base station B, the base station C, and their circular communication areas. When the mobile phone terminal is communicating with the base station A, the base station B, and the base station C, the mobile phone terminal exists in the area of the symbol a. Therefore, the position of the mobile phone terminal can be estimated based on the installation position of such a base station. FIG. 6 is a diagram illustrating a data example of base station position information stored in the base station position information storage unit 109. In the base station position information, a base station ID for identifying a base station, a latitude indicating the installation position of the base station, and a longitude are associated with each other. Here, when estimating the position of a mobile phone terminal from the position of a communicable base station, for example, the antenna directivity of the base station, whether there are many or few tall buildings around the base station, Based on the above, the range of the communication area may be determined by multiplying the radio wave arrival range of the base station by a coefficient.

  In the position information generation unit 110, the determination unit 106 determines in advance a matching rate between the first voice print information stored in the voice print information storage unit 102 and the second voice print information generated by the voice print information generation unit 105. If it is determined that the threshold value is not exceeded, position information indicating the position of at least one of the communication source terminal 10 and the communication destination terminal 20 is generated. Here, the position information generation unit 110 determines whether at least one of the telephone numbers of the communication source terminal 10 and the communication destination terminal 20 is a fixed telephone number or a mobile phone number, and the fixed telephone If it is a number, the position information associated with the telephone number is read from the fixed telephone position information storage unit 108, and if it is a mobile phone number, it is associated with the base station corresponding to the telephone number. The position information is read from the base station position information storage unit 109. For example, when the purpose is to prevent wire fraud, the location information of the communication destination terminal 20 is generated, and when the purpose is to identify the sender of the wire fraud, the location information of the communication source terminal 10 is generated. . In the present embodiment, description will be made assuming that position information of the communication source terminal 10 and the communication destination terminal 20 and both are generated.

  The communication history storage unit 111 stores a plurality of pieces of position information generated by the position information generation unit 110. FIG. 7 is a diagram illustrating a data example of communication history information stored in the communication history storage unit 111. The communication history includes a communication source number, a communication source telephone type, a communication source latitude / longitude, a communication source A latitude / longitude, a communication source B latitude / longitude, a communication source C latitude / longitude, and a communication destination. Information in which a number, a telephone type of a communication destination, a communication destination latitude / longitude, a communication destination X latitude / longitude, a communication destination Y latitude / longitude, and a communication destination Z latitude / longitude are associated with each other is included. The communication source number is the telephone number of the communication source terminal 10. The communication source telephone type indicates whether the communication source telephone is a fixed telephone or a mobile phone. For example, “0” is stored in association with a fixed phone, and “1” is stored in association with a mobile phone. The communication source latitude / longitude is the latitude / longitude corresponding to the fixed telephone number when the communication source terminal 10 is a fixed telephone. The communication source A latitude / longitude, the communication source B latitude / longitude, and the communication source C latitude / longitude are a plurality of base stations that communicated with the mobile phone when the communication source terminal 10 is a mobile phone. Each latitude and longitude. Similarly, the communication destination number is the telephone number of the communication destination terminal 20. The destination telephone type indicates whether the destination telephone is a fixed telephone or a mobile phone. The communication destination latitude / longitude is the latitude / longitude corresponding to the fixed telephone number when the communication destination terminal 20 is a fixed telephone. The communication destination X latitude / longitude, the communication destination Y latitude / longitude, and the communication destination Z latitude / longitude are a plurality of base stations that communicated with the mobile phone when the communication destination terminal 20 is a mobile phone. Each latitude and longitude. The transmission start date and time is the date and time when telephone communication is started. The call end date and time is the date and time when the telephone communication is ended. The call time can be calculated from the difference between the call start date and time and the call end date and time.

The map image storage unit 112 stores map images in advance. The map image is stored so that a map of an arbitrary location can be detected according to the latitude and longitude.
The communication position map image generation unit 113 reads a map image stored in the map image storage unit 112, and performs communication with an index added to the position indicated by the position information generated by the position information generation unit 110 in the read map image. A location map image is generated. FIG. 8 is a diagram illustrating a data example of the communication location map image of the fixed telephone generated by the communication location map image generation unit 113. In the communication position map image, an index indicating the communication position of the fixed telephone is attached to a location indicated by a symbol a. FIG. 9 is a diagram illustrating a data example of the communication position map image of the mobile phone terminal generated by the communication position map image generation unit 113. In the communication position map image, an index indicating the communication position of the mobile phone terminal is attached to the location indicated by the symbol a. Here, the communication position map image generation unit 113, as shown in FIG. 10, has a communication position map image in which indices are attached to a plurality of positions corresponding to a plurality of pieces of position information stored in the communication history storage unit 111, respectively. May be generated. Such a communication position map image may be enlarged and reduced by a user operation.

Next, an operation example of the communication system 1 according to the present embodiment will be described. FIG. 11 is a flowchart illustrating an operation example of the information server apparatus 100.
When the communication source terminal 10 makes a call to the communication destination terminal 20, the communication destination terminal 20 receives a call, and telephone communication between the communication source terminal 10 and the communication destination terminal 20 is started, the information server device 100 The voice receiving unit 104 receives voice communicated between the communication source terminal 10 and the communication destination terminal 20 (step S1).

  The voiceprint information generation unit 105 generates voiceprint information based on the voice information received by the voice reception unit 104 (step S2). Here, the voiceprint information generation unit 105 can store the voice information (communication contents) of the communication source terminal 10 and the communication destination terminal 10 as separate files and generate voiceprint information based on the respective voices. . The determination unit 106 reads out the voice print information of the partner user stored in the voice print information storage unit 102 in association with the user ID of the communication destination terminal 20, and transmits the voice print information (transmitted from the communication source terminal 10) in step S2. The voiceprint information generated based on the voice information) is compared with a plurality of voiceprint information read from the voiceprint information storage unit 102 (step S3). If the determination unit 106 determines that there is registration information in which the matching rate between the voiceprint information generated in step S2 and the voiceprint information read from the voiceprint information storage unit 102 exceeds the threshold (step S3: YES), the process ends. To do. In this case, since it can be estimated that the call is from a predetermined relative, there is no need to perform a warning process or the like.

  On the other hand, in step S3, the determination unit 106 determines that there is no registration information in which the matching rate between the voiceprint information generated in step S2 and the voiceprint information read from the voiceprint information storage unit 102 exceeds the threshold (step S3). : NO), the position information generation unit 110 generates the position information of the communication source terminal 10 and the position information of the communication destination terminal 20 (step S4), and stores the communication history information in the communication history storage unit 111 (step S5). ). Then, the communication position map image generation unit 113 generates a communication position map image with an index added to the position information generated by the position information generation unit 110 (step S6). The warning unit 107 outputs a warning to a predetermined destination together with the communication position map image generated in step S6 (step S7).

  Here, in the present embodiment, an example is shown in which the determination unit 106 stores one threshold value and estimates that there is a possibility of wire fraud when the matching rate does not exceed the threshold value. However, a plurality of threshold values are provided. Thus, stepwise determination may be performed. For example, when a first threshold value (for example, 80%) and a second threshold value (for example, 30%) lower than the first threshold value are provided, and the coincidence rate exceeds the first threshold value (80% or more) Is determined to be a relative or the like, and if it is below the second threshold (less than 30%), it is determined that there is a possibility of a transfer fraud. If the match rate is between the first threshold value and the second threshold value (30% or more and less than 80%), there is a possibility of wire fraud taking into account information such as call time and phone area, for example. It is determined whether or not. In this case, for example, the determination unit 106 calculates a call time based on information stored in the communication history storage unit 111 and compares the call time with a predetermined threshold value to make a determination. For example, if the call time is long (for example, 1 hour or more), it can be considered that there is a high possibility that the conversation is between acquaintances. In addition, when a call is made from an area that is often the source of a transfer fraud, it can be considered that the possibility of a transfer fraud is relatively high. Such a possibility is converted into a numerical value, and a process when the coincidence rate is between the first threshold value and the second threshold value is determined. In addition, for example, if the call is in the middle of the night or early morning (for example, from 22:00 to 7:00 the next morning), which is outside the bank ATM operating hours, the possibility of wire fraud is low and is not subject to the judgment process. It is also good.

In addition, the determination unit 106, in addition to comparing with the voiceprint information of a predetermined relative, etc., for example, in order to prevent the telephone communication from the courier service provider is determined to be a transfer fraud, A telephone number such as a courier service provider may be set in advance, and the telephone communication made from the preset telephone number may not be determined as having the possibility of a transfer fraud.
Further, for example, when there is voiceprint information based on the voice of a person who is highly likely to make a transfer fraud based on information from other communication histories or police, the determination unit 106 determines such a voiceprint. The information may be compared with voiceprint information based on the voice of the person who made the call, and if the matching rate is greater than a certain level, it may be determined that there is a possibility of wire fraud.

  Moreover, although the communication position map image generation part 113 demonstrated the example which produces | generates a communication position map image based on the some communication log | history memorize | stored in the communication log | history memory | storage part 111, in this case, the defined conditions Based on the above, a communication position map image with a position information index corresponding to a communication history in an arbitrary range may be generated. For example, a transmission date and time period, a communication area, a call time, and the like may be set as conditions, and a communication position image with an index added only to position information based on communication history that matches the conditions may be generated.

  Further, the user information registration unit 103 issues a password or the like to the user of the communication destination terminal 20, and provides a management web screen for confirming and editing the user information or the like stored in the information server device 100. can do. For example, if the voice information is registered but the voiceprint information is not generated correctly, or if the voiceprint determination result is not correct due to a change in the voice of a growing child, the correct determination is made as a result of the voiceprint diagnosis. This is useful when re-recording audio information that you do not expect. Such a management web screen has a function of playing back, deleting, or re-registering registered voice information. Here, in the case of re-registration, a callback is made to an arbitrary telephone number designated by the user, and voice registration is performed.

  Further, the determination unit 106 may perform the determination process immediately when the voice reception unit 104 receives the voice of the telephone communication, but may start the determination process at an arbitrary timing. For example, an adapter having a button may be connected to a USB (Universal Serial Bus) terminal of a home broadband service home gateway, and the determination process may be started when this button is pressed. In this case, the warning may be output by the adapter having a lamp and lighting or blinking the lamp. Here, the warning may display an interrupt image indicating the warning on a television screen in the home. Alternatively, the arbitrary trigger may be, for example, a push sound when a specific button (such as “#” or “*”) of the telephone terminal is pressed.

  As described above, according to the present embodiment, for telephone communication with an uncertain sender, the system automatically determines whether the sender is a relative or a related party, and the sender of the transfer fraud It is possible to generate a map image that allows the third party to visually recognize the region and the region to which the fraud fraud is transmitted. Thereby, the effect which prevents generation | occurrence | production of the transfer fraud etc. which used the telephone can be anticipated. In addition, according to the present embodiment, it is also possible to save the content of a call from a sender having a high possibility of a transfer fraud, so the keyword used by the telephone fraud method of the transfer fraud from the saved call content It is also possible to identify a caller who has a high possibility of performing a fraud scam by detecting the above.

  The present invention can also be applied in the financial industry to enhance security for identity verification at bank counters and telephone banking, and to improve services such as speeding up. Alternatively, in the medical industry, it can be applied to an electronic medical record search for telephone medical care for a person living in a remote place, and service improvement such as speeding up of identity verification when prescribing a medicine. Or, it can be applied to various procedures such as pension procedures, receipt, resident's card, seal verification, etc. in the government office, strengthening the security of identity verification, and improving services such as speeding up.
