Description

  The present invention relates to a call connection control device, a telephone terminal, and a telephone network that provide a high-function telephone service, and in particular, to prevent or prevent crimes such as fraud and bad commercial law using the telephone. The present invention relates to a technology for improving the safety of subscribers using a telephone.

There are many other crimes such as wire fraud and ole fraud, such as fraudulently scamming someone else over the phone, guiding the victim to transfer money to a designated account, or handing cash. Despite the cautions from the police station and the introduction of techniques by media reports such as television and radio, many new techniques were considered or forgotten old techniques were re-established. It is done using.
In addition, malicious sales phones that semi-forcefully sell expensive products are also a threat to elderly consumers, and the Consumer Affairs Agency and others are pushing forward with measures against unscrupulous sales.
On the other hand, as a conventional technology, a service that displays the telephone number of the outgoing telephone by contracting with the telephone carrier is widely used on a telephone with a liquid crystal display attached to the telephone, and when the telephone rings It is also possible to repel malicious calls by checking the caller number and picking up the handset. However, many of the victims are elderly, and such people generally use phones that do not have a liquid crystal display and cannot display phone numbers. Therefore, it is impossible to know who the caller is without picking up the handset. In this case, you may get caught up in various techniques on the criminal side, leading to damage.
In order to prevent such crimes using the telephone, Patent Document 1 proposes a bank transfer fraud prevention system. In this system, using the voice recognition technology with the notification from the person who has already become a victim, the biometric information by the scammers' voice data and the account number or crime specified by the scammers in words By listening to terms that are easy to use, the telephone receiver and the police are notified of the result according to the degree of coincidence of these data.

JP 2008-210085 A

As mentioned in the background section above, the tricks of fraud continue to change skillfully, and if you do not use the same account number again or in a form that does not say the information corresponding to the account number in the call There are also reports of payment methods, and the device of Patent Document 1 cannot take pre-measures against new threats. Crimes may not be known to the world. Therefore, the first problem to be solved by the present invention is that a new method of fraud using the telephone occurs for telephone subscribers who want to protect themselves or their relatives and relatives from crimes using the telephone. In this case, it is necessary to eliminate the first victim as much as possible or to remain unaware of telephone fraud.
In addition, when a fraudster changes the voice and makes a call, the degree of coincidence with the already registered biometric information (voice data) is likely to decrease, and even in this case, fraud crimes cannot be extracted. It is done. Therefore, the second problem to be solved by the present invention is to apply to the telephone control technology a voice recognition technology that focuses on terms frequently used in fraud using telephones without relying on human voice quality. is there.
In addition, scammers may make crimes by creating a large team, and they rarely use criminal terminology in a single call, with calls from several different phone numbers. One story may be created, and the system cannot determine each phone call as a fraud crime, and as a result, the call recipient may be damaged. Therefore, the third problem to be solved by the present invention is to extract one crime by associating each telephone with a fraud performed by a combination of several other telephones. is there.

  In order to solve the above problems, the telephone network has a database with sound piece data that can flexibly respond to changes in fraud techniques, and a fraud countermeasure device capable of controlling telephone calls is deployed, and a fraud countermeasure function is provided. For calls that are received from telephone subscribers who want to enjoy the services provided by, first, a guidance is sent to both the caller and callee that clearly indicates that the call is connected with the anti-fraud function activated. When a call connection is established, the voice from the caller and the callee is recognized using speech recognition technology, and when a term frequently used in fraud is detected, the call is disconnected or the call is disconnected. If there is a high possibility that a call made earlier from the anti-fraud device is likely to be a fraud to a recipient or a party related to a preset recipient, Require arouse means the attention your business. It also has a means to record calls with high possibility of fraud, presents the contents of the call to experts, extracts new terms that can deal with new tricks from experts, and newly adds these terms to anti-fraud devices. Have a way to register and be prepared for new tricks.

According to the first solution of the present invention,
A call connection unit for detecting a call from a calling telephone and connecting the telephones according to a telephone number of an incoming telephone;
A voice recognition unit for recognizing call voice;
A synthesized voice output unit that outputs synthesized voice based on a plurality of voice data stored in advance;
With
When a predetermined number of pre-registered fraud terms that are frequently used in fraud using a telephone are detected while recognizing call voice between telephones connected by a call, a communication path between the synthesized voice output unit and the incoming telephone is secured. A call connection control device is provided that transmits a synthesized voice that calls attention to the incoming telephone.

According to the second solution of the present invention,
A call connection unit for detecting a call from a calling telephone and connecting the call;
A voice recognition unit for recognizing the voice of the call with the calling telephone;
A synthesized voice output unit that outputs synthesized voice based on a plurality of voice data stored in advance;
With
Provides a phone terminal that outputs a synthesized voice prompting attention or displaying a screen prompting attention when it detects a predetermined number of pre-registered fraud terms that are frequently used in fraud using the telephone while recognizing the call voice Is done.

According to the third solution of the present invention,
The above phone terminal,
An information storage device for storing information on fraudulent calls detected by the telephone terminal;
When the telephone terminal detects a predetermined number of fraud terms, a fraud countermeasure telephone network is provided that transmits call information related to the call to the information storage device.

In the conventional technology, if you do not use the same account number again, or if you do not take the precautions against new tricks to pay in a form that does not say the information corresponding to the account number during the call, There was a possibility that victims appeared at the beginning of the new trick, or the crime was unknown to the world without being aware even if it was damaged. In addition, when a fraudster makes a call with a different voice, there is a high possibility that the degree of coincidence with already registered biometric information (voice data) will decrease, and in this case, fraud crimes may not be extracted. It was. Furthermore, when scammers make a large number of teams and commit a crime, they rarely use criminal terms in a single call and make a story with calls from several different phone numbers. The system could not determine each phone call as a fraud crime, and as a result, there was a possibility that the call recipient could be damaged.
On the other hand, in the present invention, when a telephone suspected of a fraud crime is established, detailed confirmation is promoted by alerting the victim side, while information is easily provided to experts of fraud crimes. Can provide a fraud countermeasure function that is highly resistant to the beginning of new tricks, changes in voice quality, tricks with multiple telephones, and so on. As a result, it is possible to improve the safety of telephone subscribers using the telephone from fraud using the telephone and unscrupulous sales that sell expensive products semi-forcibly. In addition, it is possible to increase the reliability of the telephone carrier that has introduced the apparatus and method and contribute to an increase in profit.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a configuration diagram of a telephone network connection form to which a fraud countermeasure device 1 using a telephone is applied and internal functions of the fraud countermeasure device 1.
The fraud countermeasure apparatus 1 is connected to another fraud countermeasure apparatus 2 via a telephone network 30 and is connected to a mobile telephone base station 41 that accommodates a subscriber telephone 40 and a mobile telephone 42 via a telephone network 32. The fraud countermeasure apparatus 1 connects the telephone network 30 and the telephone network 32 with a call control line 35 and a call control line 37 for communicating control signals such as a call connection request, and a telephone line 36 for communicating a voice signal. In addition, the communication line 38 is connected. Connected to the telephone network 30 is an operation center 50 for managing the service contract form and service provision fee of each telephone subscriber. In addition, a call connection control device 60 that does not have a fraud countermeasure function may be connected to the telephone network 30. The fraud countermeasure device 2 is connected to a mobile phone base station 44 that accommodates a subscriber phone 43, a mobile phone 45, or a mobile phone 46 via the telephone network 34 on the terminal side. The telephone network 30, the telephone network 32, and the telephone network 34 described so far may be networks of the same company or different companies.
The internal configuration of the fraud countermeasure apparatus 1 includes a call connection control unit 11 that controls the connection state of a call when a call connection request is issued and controls the connection state of the call according to the provided service contents registered in the database, A call connection processing unit 12 that can connect a number of calls that can be realized by a so-called time-division switch or the like that connects a speech path by setting from the connection control unit 11 and a voice in real time during a call In addition to having a function to mark the term when it is recognized or recorded, especially when frequently used in fraud crimes, it has a PBR (Push Button Receiver) function and a DPR (Dial Pulse Receiver) function The voice recognition unit 13 and the fraud prevention service clearly indicate that the call is applicable to this service, The voice synthesizer 14 that sends a voice guidance that warns that the dropped call is likely to be a fraud or that guides the registration status of the contract to this service, and the recognition result obtained by the voice recognition unit 13 A device control unit 15 having a function of notifying determination information which is a basis for determination of how to perform call content display processing and call connection processing based on the above, or determining the content of voice guidance to be transmitted to the caller; The subscriber telephone connected to the subordinate of the fraud countermeasure device 1 is registered with the subscriber telephone number subscribed to the fraud countermeasure service, and the telephone number of the caller at the time of the call for the subscriber telephone number registration, A service subscriber database that stores contact phone numbers to be notified when a service subscriber is likely to be scammed, as well as phone numbers of relatives who are not likely to be fraudulent. 10, a call log database 16 for storing the contents of the call under the application of the service, text and recording, and the incoming / outgoing telephone number and date / time when the call was made, and the voice recognition unit 13 executes the voice recognition process A speech data unit for recognition 17 for storing speech data to be referred to, and a speech database unit for synthesis 18 for storing speech data as original data for creating guidance related to the service in the speech synthesizer 14. .

The fraud countermeasure device 1 displays a warning issued from the device control unit (determination unit) 15 when there is a high possibility that a fraud crime has occurred in a certain call, and stores a call log database related to the call. 16 contents are displayed, voice data for voice recognition that is a countermeasure against new fraud techniques is edited and registered in the voice database 17 for recognition, and warnings and countermeasures for new fraud techniques are displayed. The voice data to be notified is edited and registered in the synthesizing voice database 18, and the fraud apparatus operating unit 20 that performs operations such as editing, registration, and changing the contents of the service subscriber database 10 is connected. The fraud apparatus operating unit 20 may be implemented by, for example, a single personal computer or workstation, or may be realized by a separate personal computer or workstation via an IP network such as a LAN. The configuration of the fraud countermeasure device 2 is the same as that of the fraud countermeasure device 1.

FIG. 2 is a configuration diagram of the service subscriber database 100 in the service subscriber database unit 10. The service subscriber database 100 stores a subscriber-one data storage area 111 for storing data relating to the first subscriber who subscribes to the fraud countermeasure service, and a subscription for storing data relating to the second subscriber who subscribes to the service. And a subscriber K data storage area 11K for storing data related to the Kth subscriber who continues to the Kth and subscribes to the service. In addition, the service subscriber database 100 stores the subscriber telephone number data storage area 130 for storing the telephone number of the service subscriber, and when it is determined that the incoming call to the service subscriber has a high possibility of fraud. Broadcast number one storage area 151 to store the first to L-th telephone numbers registered as destinations for alerting attention, and broadcast number L storage area 15L, and telephone subscribers who enjoy the service The connection permission number one storage area 171 to the connection permission number M storage area 17M for storing the first to Mth telephone numbers that are not subject to the operation of the service device, and the service device, and the service Suspicious number one storage area 191 to suspected for storing first to Nth outgoing telephone numbers in which the service device is determined to have a high possibility of fraud crimes among telephones that are received by subscribers No. includes N storage area 19N, a. Note that the above-mentioned K, L, M, and N are appropriate natural numbers.
A telephone subscriber who wants to enjoy the fraud countermeasure service is registered in the last (K + 1) th column of the subscriber telephone number data storage area 130 of the service subscriber database 100 by making a contract with the telephone carrier. At the same time, when a phone call with the possibility of a fraud crime is received, for example, to deliver a warning that a fraud call has been received to the subscriber to relatives and relatives such as their children. The subscriber's relatives and relative telephone numbers can be registered from the broadcast number one storage area 151 to the broadcast number L storage area 15L. Similarly, for incoming calls from people who are clearly trusted, such as their own children or relatives, the subscriber's children and relatives of the subscribers are able to make calls by skipping the redundant operation of the service. M telephone numbers from the connection permission number 1 storage area 171 to the connection permission number M storage area 17M can be registered.
If it is determined that a call with a high probability of N fraud crimes has been made to the recipient of the fraud countermeasure service, the outgoing telephone number of the call is assigned to the suspected number associated with the service recipient. N pieces from the storage area 191 to the suspected number N storage area 19N are stored and used as information for processing after the call ends. The database 100 is unique in its data acquisition method and registration contents, but it is often the case that the amount of information differs for each service subscriber as means for realizing the structure of the database. The storage capacity may be saved by using an existing relational database system or the like. A method for automatically generating the service subscriber database 100 will be described later.

  FIG. 3 shows a fraud confirmed telephone number database 300 that is confirmed as a telephone number used for fraud in the fraud countermeasure service. This database 300 is in the service subscriber database unit 10 and has a storage area for a confirmed fraud phone number P (30P) from a confirmed fraud phone number (301) which is a phone number used for fraud, which will be described later. By communicating between the street fraud countermeasure devices, all the fraud countermeasure devices have the same database 300. In addition, when receiving a call to a fraud countermeasure service recipient, in order to determine whether or not the call connection is permitted, the call connection control unit 11 inquires the calling telephone number as the first operation. It is. In addition, since telephone numbers registered in this database can never be received by those who enjoy fraud countermeasure services, there is a possibility that many telephone numbers that cannot be reused will be generated even if the applicable telephone subscription is canceled. high. Accordingly, the telephone number registered in the database 300 can be deleted using the fraud countermeasure apparatus operation unit 20 when the contract is canceled. The erasing process will be described later.

  FIG. 4 shows a database of telephone subscriber data. The database 400 is a database in which information is added to a subscriber database generally used for a telephone exchange or a call connection server in the telephone business. However, in the present invention, there is a high possibility that fraud using a telephone is particularly generated. It is used for broadcast communication and automatic registration for this service. The subscriber database 400 will be described. Q subscribers (Q is a natural number) are registered, and personal information is stored in the range of 411 to 41Q, respectively. Each stored content includes a subscriber telephone number 420, a subscriber name 430, shime data 440 used for sending voice data, and a mail address 450. In addition, as a telephone service that can be freely selected by each individual, for example, there is a telephone number display service, for example. Contract service service (461) to contract service R (46R), which are areas showing such contract service, are also available. However, since these data are not used in the present invention, they are not specified.

  FIG. 5 is an example of a call connection sequence for a fraud countermeasure service subscriber. In this example, it is assumed that a call connection is made from the telephone 46 to the telephone 40 subscribing to the fraud countermeasure service. First, the telephone 46 makes a call by dialing the telephone number of the telephone 40, for example, the telephone number “8612410” corresponding to the area 130 in the area 112 of FIG. 2, and makes a connection request 501 to the fraud countermeasure device 2. For the call connection control signal corresponding to the connection request 501 at this time, SIP (Session Initiation Protocol), a common line signal system, or the like may be used. The fraud countermeasure device 2 receives the connection request 501 of the telephone 46 and notifies the call connection control unit 11 in the fraud countermeasure device 1 of the connection request 502. The call connection control unit 11 accesses 503 the service subscriber database 10 for the incoming telephone number “8612410” notified from the fraud countermeasure device 2, and stores the service subscriber database 100 in the service subscriber database unit 10. Of these, the first to Kth subscriber telephone numbers 130 are read (504). The read data group (for example, the subscriber telephone number 130) is compared with the incoming telephone number to determine whether the incoming telephone number is subscribed to the fraud countermeasure service. This determination process A1 (600) will be described with reference to FIG. In this example, it is obtained that the incoming telephone number “8612410” exists second, which is the subscriber number 112 in the subscriber database 100. From this result, the call connection control unit 11 requests 505 the notification of the calling telephone number to the fraud countermeasure device 2 on the calling side. The fraud countermeasure apparatus 2 receives the call telephone number notification request 505 and notifies the call connection control unit 11 of the call telephone number 506. The call connection control unit 11 stores the received caller telephone number, reads the fraud confirmation telephone number database 300 in the subscriber database unit 10, and inquires about the P data groups and the calling telephone number, It is determined whether or not the same number exists. This determination process A2 (620) will be described with reference to FIG. In this description, as a result of the determination process of A2, it is assumed that the corresponding calling telephone number is neither a confirmed fraud number, a suspected number, or a connection permission number. The call connection control unit 11 transmits 510 notification 1 shown in FIG. 10 to be described later to the device control unit 15, and then the call connection control unit 11 sends the call telephone 46, the voice synthesis unit 14, and the voice to the call connection processing unit 12. An instruction to secure a communication path between the recognition unit 13 and the incoming telephone 40 is issued (511). In response to this instruction, the call connection processing unit 12 secures a call path with the calling telephone 46 (512), secures a call path with the voice synthesis unit 14 (513), and secures a call path with the voice recognition unit 13 ( 514). On the other hand, the device control unit 15 activates the speech synthesis unit 14 (515) and activates the speech recognition unit 13 (516). The call connection processing unit 12 secures a communication path to the incoming telephone 40 and calls (517). When the incoming phone 40 is off-hooked, off-hook information is notified to the call connection control unit 11 (518), and the call connection control unit 11 that has detected the off-hook notifies the device control unit 15 that there has been a response from the incoming phone. (519). Upon receiving this notification, the device controller 15 issues a voice guidance transmission instruction to the voice synthesizer 14 (520), and the voice synthesizer 14 directs both incoming and outgoing calls 40 and 46 to, for example, “This call is , We will connect you under a fraud countermeasure service using a telephone. ”(521 and 522). By playing such voice guidance, at this point in time, there is a high possibility that the calling telephone will disconnect the call if it is truly malicious. When the guidance is completely transmitted, if both the incoming and outgoing calls are not disconnected, the call (523 and 524) starts. The call is recognized and recorded by the voice recognition unit 13 (525) and stored in the call log database unit 16 in real time (526). In the call log, the device control unit 15 reads the data in which the voice is converted into the text by the voice recognition unit 13, and monitors the presence / absence of the fraud term (527). Processing 526 and 527 will be described later together as processing C (800). Further, when a fraud occurs, a process D1 (820) for sending a voice guidance to alert the callee is performed. This process will also be described later.

FIG. 6 is an example of a flowchart of the process A1 (600) used in FIG. 5 described above.
When the process A1 (600) is operated, first, the incoming telephone number already received by the call connection control unit 11 is stored in α (601). Next, a variable β is defined, and 0 is set as an initial value (602). The variable β varies in the range from the first to the Kth of the subscriber number 130 of the service subscriber database 100. (β + 1) is stored in β (603), that is, β = 0 + 1 = 1 in the first stage, so β = 1 is stored. With respect to the value of β, the subscriber telephone number corresponding to the βth in the service subscriber database 100 is set to γ (604), and the value of α which is the incoming telephone number is matched (605) to obtain the values of α and γ. Are determined to be the same (606). Here, if the values of α and γ are different, it is further determined whether or not β is the Kth, that is, whether or not the end of the subscriber telephone number 130 of the service subscriber database 100 has been reached ( 607). If β has not reached the Kth, the process returns to step 603, and 1 is further added to β to proceed with the same process as described above. If the values of β and K are the same, it is concluded that the incoming telephone 40 is not a beneficiary of the fraud countermeasure service, and the call connection control unit 11 calls the call connection processing 12 to connect the outgoing telephone 46 and the incoming telephone 40 to each other. The process proceeds to the instruction (608), and a normal call connection is performed. The sequence for this normal call connection is shown in FIG. If α and γ coincide with each other in the determination process 606, it is concluded that the incoming telephone 40 is a beneficiary of the fraud countermeasure service, and the call connection control unit 11 sends the calling telephone number to the fraud countermeasure apparatus 2 on the calling side. The process shifts to a notification request (609), and executes the sequence shown in FIG. Note that the processing 609 is omitted because there is a case where the call connection request data includes the telephone number information of the calling telephone when a call connection request has already been made from the calling side fraud countermeasure device. It is also possible. On the other hand, when a call connection request is issued from a calling phone without notification of the phone number, and the fraud countermeasure device that accommodates the incoming phone cannot obtain the calling phone number, It may be defined that the calling telephone numbers are forcibly communicated between the countermeasure devices, or it may be defined that the call connection is not performed when the telephone number is not notified.

FIG. 7 is an example of a flowchart of the process A2 (620) used in FIG. 5 described above.
When the process A2 (620) is operated, first, the calling telephone number already received by the call connection control unit 11 is stored in δ (621). Next, a variable ε is defined, and 0 is set as an initial value (622). The variable ε changes in the database area to be referred to depending on the value. When ε is 1, the fraudulent telephone number database 300 is displayed. When ε is 2, the connection permission number area (171 to 17M in the service subscriber database 100). When ε is 3, the suspicious number area (191 to 19N) in the service subscriber database 100 is referred to. The value of (ε + 1), that is, 0 + 1 = 1, is stored in the initial value 0 (623), the value of ε is determined 624, and if ε is 1, the final value of the confirmed fraud phone number in ζ P is stored 625. If ε is 2, M is the last value of the connection permission number in ζ. If ε is 3, N is the last value of the suspected number in ζ 627. . Next, a variable η is defined, and 0 is set as an initial value (628). The variable η varies in the range from the first to the last telephone number of each database reference area. (η + 1) is stored in η (629), that is, η = 0 + 1 = 1 in the first stage, so η = 1 is stored. With respect to the value of η, the telephone number corresponding to the ηth of the reference destination area determined by ε is stored in 630 (630), and δ and θ which are outgoing telephone numbers are compared 631. If the numbers of δ and θ are the same, the process proceeds to processing 633. If the numbers of δ and θ are different, a comparison 634 is performed between the variable η and ζ, which is the last value of each database area. If η and ζ do not match, it is not possible to collate until the end of the reference database, so the process returns to process 629 to repeat the process. If η and ζ match, the collation is completed up to the end of the reference database, and the value of ε is checked 635. If the value of ε is 1 or 2, there is still room for referring to another database, so the process returns to process 623 and the process is repeated. When the value of ε becomes 3, since the calling telephone number does not exist in the three database areas referred to in the process A2 (620), the process proceeds to A6 (660).
In process 632, when the calling telephone number is found in the database, the process branches to three according to the value of ε (633). That is, the process branches depending on whether the calling telephone number is a confirmed fraud telephone number, a connection permission number, or a suspected number. When ε is 1, the process proceeds to A4 (640). When ε is 2, the call connection processing unit 12 is notified of a call connection instruction between the calling telephone 46 and the incoming telephone number 40, and when ε is 3, A5. Move to (650).

FIG. 8 is a diagram showing an example of the flow of processing after A4 (640), A5 (650), and A6 (660) shown in FIG.

First, in A5 (650), the call connection control unit 11 transmits 651 a notification 1 including the parameter 2 to the device control unit 15, which will be described later. Subsequently, the call connection control unit 11 instructs the call connection processing unit 12 to call connection between the calling telephone 46 and the voice synthesis unit 14 652. Next, the call connection control unit 11 instructs the call connection processing unit 12 to call connection between the incoming telephone 40 and the voice synthesis unit 653. Next, the call connection control unit 11 instructs the call connection processing unit 12 to call connection between the incoming telephone 40 and the voice recognition unit 13 654 and completes the process.
A6 (660) operates when the calling telephone number is neither a confirmed fraud telephone number, a connection permission number, or a suspected number. First, in process A6 (660), the call connection control unit 11 transmits 661, including the parameter 1, to the device control unit 15 as described later. Subsequently, the call connection control unit 11 instructs the call connection processing unit 12 to call connection between the calling telephone 46 and the voice synthesis unit 14 662. Next, the call connection control unit 11 instructs the call connection processing unit 12 to call connection 663 between the incoming telephone 40 and the voice synthesis unit 14. Next, the call connection control unit instructs the call connection processing unit 12 to call connection between the calling telephone 46 and the voice recognition unit 13 664. Further, the call connection control unit 11 instructs the call connection processing unit 12 to call connection 665 between the incoming telephone 40 and the voice recognition unit 13. Finally, the call connection control unit 11 instructs the call connection processing unit 12 to call connection between the calling telephone 46 and the incoming telephone 40 and completes the processing.

  FIG. 9 is a diagram showing an example of the process flow of process B (700) used in FIG. In process B (700), the device control unit 15 first detects 701 a notification from the call connection control unit 11. Although details of the contents of the notification will be described later, if the parameter in the notification data is 3 (702), the apparatus control unit 15 notifies the speech synthesis unit 14 of an operation instruction 4 described later 706. If the parameter is not 3 (702) but 2 (703), the apparatus control unit 15 notifies the speech synthesis unit 14 of an operation instruction 2 (to be described later) 705. If the parameter is not 2 (703) but 1, the apparatus control unit 15 notifies the speech synthesis unit 14 of an operation instruction 1 described later 704.

  FIG. 10 is a diagram illustrating a configuration example of instruction data communicated between the call connection control unit 11 and the device control unit 15. The instruction data 750 includes, for example, four data areas, a notification number area 751, a call identifier area 752, a notification content area 753, and an additional information area 754. The notification number 751 is instruction data for determining what operation the call connection control unit 11 and the device control unit 15 should move to each other. In the configuration shown in FIG. Expressed numerically. The call identifier 752 is used to uniquely identify which telephone is connected to which telephone for the connected call, and is expressed by an arbitrary integer value. The notification content 753 defines the operation instruction of the notification number 751 in more detail, and is expressed by an arbitrary integer value in the configuration shown in FIG. The additional information 754 includes additional information necessary for executing an operation instruction, and is expressed by a character code or the like in addition to an integer value.

  FIG. 11 is an example of a call identifier management table created and managed by the call connection control unit 11 with information on the call identifier described in FIG. The call identification management table 760 stores a call identifier represented by an arbitrary integer value, an outgoing telephone number, and an incoming telephone number in association with each other. For example, each piece of information is stored at an appropriate timing of the call connection process and deleted by disconnecting the call.

  FIG. 12 is a diagram showing an outline of the operation instruction notification from the apparatus control unit 15 to the speech synthesis unit 14 described in FIG. The operation instruction notification data 770 includes an operation instruction area 771 and an additional information area 772. The operation instruction 771 instructs the voice synthesis unit 14 to perform operations such as voice guidance transmission preparation, voice guidance transmission, and voice guidance stop, and is expressed by an arbitrary integer value in the configuration shown in FIG. To do. The additional information 772 is an area including information necessary for performing the operation, such as a telephone number and a person name, and is expressed by an integer value or a character code.

FIG. 13 is an example of a table summarizing the guidance sent from the speech synthesizer in response to the notification data shown in FIG. The operation instruction numbers in FIG. 13 correspond to the operation instruction numbers in FIG. 12, and define the case where the same guidance is sent to both outgoing and incoming calls, or the case where different guidance is sent and received. Further, it is stipulated that the telephone number and the person name included in the additional information of the notification data in FIG.
Note that the guidance content of the operation instruction 5 in FIG. 13 shows an example in which the “family” and “police” are set to be contacted, but it is shown in FIG. 36, FIG. 37, FIG. If the voice guidance is transmitted after changing the contact destination according to the result of the voice recognition to a word such as “tax office”, the telephone subscriber can be urged to contact the appropriate organization. At this time, in the recognition data for fraud monitoring shown in the operation instruction 2 of FIG. 15, terms that can indicate the report destination, for example, “Kayatsu”, “Ginkgo”, “Bengoshi”, and the like are special additional information, If recognized, it may be highlighted by enclosing with special special symbols in the process 814 of FIG.

  FIG. 14 is a diagram illustrating an example of a configuration of notification data used when the device control unit 15 instructs the voice recognition unit 13 to perform an operation. The notification data 790 includes an operation instruction area 791 and additional information 792. The operation instruction 791 is classified into 1: connection confirmation, 2: fraud monitoring, 3: report recognition, 4: contract recognition, and the operation mode is changed so that the voice recognition data to be referred can be changed. Also, 99: Stops the speech recognition process at the stop of recognition. The additional information 792 is used for expansion.

  FIG. 15 is an example of a table defining the operation of the voice recognition unit 13 based on the operation instruction shown in FIG. The operation instruction in FIG. 15 corresponds to the operation instruction in the notification data in FIG. For example, when the operation instruction is 1: connection confirmation, the voice recognition unit 13 recognizes voice for the incoming side. In the case of connection confirmation, the number of words to be recognized is narrowed down, and words such as “high”, “no”, “tunag”, “tunaganai”, etc. are set as recognition target words. The same applies to 2: fraud monitoring, 3: report recognition, 4: contract recognition.

FIG. 16 is a diagram showing an example of the flow of the process C (800) described in FIG. First, in the process C, the voice recognition unit 13, the device control unit 15, and the call log database unit 16 operate in cooperation. The operation of the device control unit 15 will be described. The device control unit 15 defines a variable s and sets 0 as an initial value (801) immediately before the start of speech recognition of a call. Subsequently, text data of a voice recognition result written from the voice recognition unit 13 to a call log database 16 as described later is read (802), and the presence / absence of fraud term is determined 803. Here, “fraud terminology” refers to words that have been registered in the fraud countermeasure device 1 in advance and are frequently used for wire fraud, such as “Oleore”, “I / I”, “Bank”, “Account”, and “Transfer”. is there. If one “fraud term” is extracted here, the device control unit 15 adds the number 1 of “fraud term” to the variable s (805).
As long as the variable s does not exceed the preset threshold value th (806), the processing from the processing 802 to the processing 806 is repeatedly executed. If the variable s exceeds the threshold value th, the device control unit 15 transmits a warning notification to the device operation unit 20 (807), and it is highly likely that the phone being talked is a fraudulent phone call. To the authorities. In addition, the device control unit 15 transmits the operation instruction 5 to the speech synthesis unit 14 (808).
In the situation where the “fraud term” is not extracted in the processing 803, the processing from the processing 802 to the processing 808 is not performed, and the processing from the processing 802 is performed until the notification whether the call is disconnected (809) is detected. Steps up to 809 are repeatedly executed. If a call disconnection notification is detected, the device control unit 15 issues an operation instruction 99, that is, an operation end instruction to the voice recognition unit 13, and if s ≧ th is established (819), the process D1 (820) )
On the other hand, the voice recognition unit 13 recognizes the voice during the call 811, and when the “fraud term” is detected 812, the fraud term is represented by a special symbol, for example, a special character such as “*”. Is made into a text 814 in a form that encloses, for example, a text such as “* Ole *” is created, and text writing 815 of the speech recognition result is executed in the call log database 16. In a situation where no fraud term is detected, the recognized words are converted into text 813 and written in text 815. In addition, the voice recognition unit 13 recognizes the call voice and simultaneously records the voice 816 and stores the recorded data in the call log database unit 16 (817).
The voice recognition unit 13 repeats this series of processing until receiving an operation stop instruction 818 from the device control unit 15.
In the processing 814, for the fraud monitoring data of the operation instruction 2 in FIG. 15, for terms that can inform the telephone subscriber of the inquiry address such as “Kei Satsu”, “Ginkgo”, “Bengoshi”, etc., for example, “$” If it is enclosed in special characters different from the above-mentioned “*”, an appropriate inquiry destination can be inserted into the alert voice guidance to be processed later and transmitted.

  FIG. 17 is a diagram illustrating an example of an operation sequence when it is detected that fraud has occurred as a result of the voice recognition processing. Steps 523 to 527 are as described above, and it is assumed that fraud has been detected in the processing so far. The call connection control unit 11 detects a call disconnection signal from the called party and notifies the device control unit 15 that the call disconnection signal has been received. Thereafter, the device control unit 15, the call connection control unit 11, and the device operation unit 20 shift to a process D 1 (820) described later, and send out voice guidance for alerting the recipient. Thereafter, the device control unit 15 proceeds to processing E1 (870), and the call connection control unit 11 proceeds to processing E2 (880), and sends a voice guidance for alerting the broadcaster. Hereinafter, the process D1 (820), the process E1 (870), and the process E2 (880) will be described.

FIG. 18 is a diagram showing an example of the flow of processing for the processing D1 (820) in FIG. First, in the processing D1, the device operation unit 20, the device control unit 15, and the call connection control unit 11 operate in cooperation. Explaining from the operation of the device control unit 15, the device control unit 15 is a phone with a high probability of fraud, as a result of voice recognition, the number of detected “fraud terms” exceeds a preset threshold. Is notified to the call connection control unit 11 by notifying 821 of the call identifier. Subsequently, the apparatus control unit 15 notifies the apparatus operation unit 20 having a function of monitoring the apparatus that there is a high possibility that a fraudulent call has occurred. After these notifications, the device control unit 15 activates the voice synthesis unit 14 823, receives a notification of call connection from the call connection control unit 11 (824), and instructs the voice synthesis unit 14 to send voice guidance. (825). For example, referring to FIG. 13, the voice guidance transmitted here has a content such as “The current phone may be a fraudulent phone call, please check with your family or consult your local police.” . In addition, in this guidance, it is necessary to receive information from the service subscriber in order to perform recognition processing from the service subscriber, which will be described later. When it is determined whether it has been found, please notify the telephone number XYZ. ” After the voice guidance is sent, a notification indicating that the call has been disconnected is received (826), and the device control unit 15 instructs the voice synthesizer 14 to stop sending the voice guidance and stop the operation (827). Go to (870).
Next, the call connection control unit 11 will be described. The call connection control unit 11 receives the notification from the device control unit 15 (830), and the call connection processing unit 12 is connected to the voice synthesis unit 14 and the incoming telephone 40. Instruct 832 to call connection 831 and incoming phone 40. When the incoming telephone responds to this call, that is, when it goes off-hook, the call connection control unit 11 detects the off-hook 833 and notifies the device control unit 15 that the call has been connected 834. When the incoming telephone is on-hook after the voice guidance is sent from the voice synthesizer 14 to the incoming telephone, the call connection controller 11 detects the on-hook 835 and notifies the device controller 15 that the call has been disconnected 836. Then, the call connection processing unit 12 is instructed to open the communication path 837. Finally, the call connection control unit 11 extracts the calling telephone number corresponding to the call identifier already notified from the device control unit 15, and uses this calling telephone number as the last number of the suspected number in the service subscriber database. Is registered 838 and the process proceeds to processing E2 (880).
The device operation unit 20 receives a warning notification from the device control unit 15 and displays a warning (840), and waits for an operator's operation (841). Processing related to the operation of the operator will be described in processing H described later.

FIG. 19 is a diagram showing an example of the flow of processing for the processing E1 (870) and processing E2 (880) described in FIG. The process E1 (870) is a process performed by the device control unit 15, and the process E2 (880) is a process performed by the call connection control unit 11. In this process, the device control unit 15 and the call connection control unit 11 operate in cooperation, and when a phone call with a high suspicion of fraud occurs to a fraudulent telephone service contractor, the broadcast number 1 shown in FIG. This is a process of sending a guidance for alerting to the report number L.
First, the operation of the call connection control unit 11 will be described. The call connection control unit 11 sets 881 an initial value 0 to a variable i representing the number of broadcasters of a certain service subscriber. The variable i varies within the range of the broadcast number areas 151 to 15L in FIG. 2 corresponding to the service subscriber telephone number. (i + 1) is stored in i (882), that is, i = 0 + 1 = 1 in the first stage, so i = 1 is stored. The i-th broadcast number corresponding to the value of i is read (883). Here, if there is data of the broadcast number (884), a call is made to the i-th broadcast number (885), and at the same time, a call notification is sent to the apparatus control unit 15 (886). The notification includes the name of the service subscriber. With regard to the name data, the call connection control unit 11 and the β-th subscriber telephone number in the service subscriber database 100 shown in FIG. Then, after collating with the subscriber telephone number 420 of the subscriber database 400 shown in FIG. 4, the shime (for voice) data 440 corresponding to the matched telephone number is used. Following this processing, the call connection control unit 11 instructs the call connection processing unit 12 to connect the speech path between the voice synthesis unit and the broadcast telephone (887), and further sends the broadcast number i telephone to the call connection processing unit 12. Direct connection to and call to When the off-hook of the broadcast number i is detected 888, the call connection control unit 11 notifies the device control unit 15 of the establishment of the call connection and prompts the voice guidance to be transmitted. Thereafter, when the on-hook of the broadcast number i is detected 890, the call connection control unit 11 notifies the device control unit 15 of call disconnection and prompts the voice guidance to be stopped. Also, the call connection processing unit 12 is instructed to release the corresponding call 892. When the flow up to this point is finished, the process returns to 882, and the broadcast number obtained by adding 1 to i is further processed.
In the determination process 884, if it is determined that there are no more broadcast numbers, the process is completed. The broadcast number i and shiime data that could not be output are stored 893 and redialed (894) after a preset time.
On the other hand, in process E1 (870) in the device control unit 15, upon receiving a call notification from the call connection control unit 11, the voice synthesis unit 14 is activated, and the name data of the service subscriber is obtained from the notified information. It is transmitted (871) to the speech synthesizer. Subsequently, a voice guidance transmission instruction 872 is issued to the voice synthesizer 14. The voice guidance used here is shown in FIG. 2, FIG. 4, and FIG. There was a phone call, please contact <Hiroshi Takahashi> as soon as possible. " Upon receiving the call disconnection notification from the call connection control unit 11, the device control unit 15 stops the operation of the voice synthesis unit 14 and ends the voice guidance transmission processing to the broadcaster.

  FIG. 20 is a diagram showing an example of a sequence for realizing a method different from the process of FIG. In this sequence, when a fraud occurs during a call, it is a sequence in the case of sending out a voice guidance that alerts the callee during the call, and there is a possibility that it is a fraud during the voice recognition in the process C (800). When it is determined that is high, the process D2 (850) operates. Processing D2 (850) will be described with reference to FIG.

  FIG. 21 is a diagram showing a flow of processing for realizing the method in FIG. This process D2 can replace the process 808 in FIG. 16 to alert the callee during the call. First, the operation of the apparatus control unit 15 will be described. The process 851 is the same as the process 821 described above, and the process 852 is the same as the process 822 described above. In process 853, the voice synthesizer 14 sends out the voice guidance. However, since the call is in progress here, the caller is alerted by superimposing the voice data of the guidance on the voice data from the calling telephone to the incoming telephone. Tell. Hereinafter, processing 854 to processing 866 are the same as those in FIG.

  FIG. 22 is a processing sequence in the case where it is determined in the processing of FIG. 6 that the incoming call is outside the provision of the fraud countermeasure service. In the process A1 (600), the next process is set to normally connect the call, and then the call connection control unit 11 establishes a call path with the calling telephone 46 and calls the incoming telephone 40 to the call connection processing part 12. Instruct (530). The call connection processing unit 12 secures a call path for the calling telephone 46 (531), and then calls the call by securing a call path with the incoming telephone 40 (532). When the incoming telephone 40 is off-hooked, the off-hook information is notified to the call connection control unit 11 (533), and the call connection control unit 11 that detects this is sent to the call connection processing unit 12 by the call of the outgoing telephone 46 and the incoming telephone 40. Connection is instructed (534), and a call between the calling telephone 46 and the incoming telephone 40 is established (535).

  FIG. 23 is a diagram showing an example of a call connection sequence when the caller telephone number is a suspected number in the process A2 (620). After the process A2 (620) is completed, when the call connection control unit 11 detects that the outgoing telephone number is the suspected number, the call control unit 11 notifies the apparatus control unit 15 that the outgoing telephone number is the suspected number ( 540). Subsequently, the call connection control unit 11 instructs the call connection processing unit 12 to secure a communication path between the calling telephone 46 and the voice synthesis unit 14 (541). In response to this instruction, the call connection processing unit 12 secures a communication path with the calling telephone 46 (542) and secures a communication path with the voice synthesis unit 14 (543). On the other hand, the device control unit 15 activates the voice synthesis unit 14 and issues a voice guidance transmission instruction (544). The voice synthesis unit 14 is directed to the calling telephone 46 as shown in the operation instruction 2 in FIG. Continue to repeatedly send (545 and 546) guidance such as "Your phone is recognized as likely to be used for fraud" until call disconnection occurs. While this guidance is being sent, the call connection processing unit 12 secures the speech path of the voice recognition unit 13 (547), secures the speech path with the incoming telephone 40 and calls the incoming telephone 40 ( 548). When the incoming telephone 40 is off-hooked, off-hook information is notified to the call connection control unit 11 (549), and the call connection control unit 11 that has detected the off-hook notifies the device control unit 15 that there has been a response from the incoming telephone. (550). In response to this notification, the device control unit 15 issues a voice guidance transmission instruction to the voice synthesis unit 14 (552). The voice synthesis unit 14 is directed to the incoming telephone 40, for example, as shown in the operation instruction 2 in FIG. A call is received from a phone number with a high possibility of fraud. The phone number is <0567668233>. Do you want to connect? " FIG. 23 shows, as an example, a case where a callee permits connection. In response to the above-mentioned guidance transmission 553, when the callee gives a positive answer to the call connection such as “Yes” or “Connect” (554), the voice recognition unit 13 recognizes the answer and the call log database. The information is stored in 16 (555). The device control unit 15 accesses the call log database 16 (556), reads the written answer (557), detects that the answer is affirmative, and sends the call connection control unit 11 to the calling telephone 46 and An instruction to perform call connection with the incoming telephone 40 is given (558). In response to this, the call connection control unit 11 instructs the call connection processing unit 12 to connect the call between the outgoing telephone 46 and the incoming telephone 40 (559), and the call between the outgoing telephone 46 and the incoming telephone 40 is connected. A call is established (560 and 561). As described with reference to FIG. 5, the voice recognition unit 13 performs voice recognition and recording (562), and the process C (800) is performed.

  FIG. 24 is a diagram showing an example of a call connection sequence in the case where it is determined in the process A2 (620) that the calling telephone number is the suspected number, as in FIG. However, a case where the callee refuses the call connection with respect to the callee guidance 553 is shown. The process up to the voice guidance transmission 553 is the same as that in FIG. 23. However, if the callee makes a negative response to the voice guidance such as “No” or “No connection” (575), the voice guidance is sent. The recognition unit 13 recognizes the answer and stores the information in the call log database 16 (576). The device control unit 15 accesses the call log database 16 (577), reads the written answer (578), detects that the answer is negative, and sends the call connection control unit 11 to the calling telephone 46 and An instruction not to perform call connection with the incoming telephone 40 is given (579). In response to this, the call connection control unit 11 holds the call connection state. The device controller 15 issues a voice guidance transmission instruction (580) to the voice synthesizer 14, and the voice synthesizer 14 gives a voice guidance such as “This phone cannot be connected” as shown in the operation instruction 3 in FIG. Continue to send to the caller until the call is disconnected or for a preset time (581 and 582). On the other hand, for the callee, as shown in the operation instruction 3 in FIG. 13, for example, a voice guidance having the content “I understand, please hang up as it is” is transmitted (583).

FIG. 25 is a diagram illustrating an example of a call connection sequence when a call connection request from a confirmed fraud phone number is generated. If it is determined in process A2 (620) that the calling telephone number is a confirmed fraud phone number, the call connection control unit 11 notifies the device control unit that it is a confirmed fraud phone number 585. Subsequently, the call connection control unit 11 instructs the call connection processing unit 12 to connect a speech path between the voice synthesis unit 14 and the calling telephone 46, and the call connection processing unit 14 secures the speech path with the voice synthesis unit 14. 587, and a communication path with the calling telephone 46 is secured 588. On the other hand, the apparatus control unit 15 receives the notification from the call connection control unit 11, activates the voice synthesis unit 14, and instructs the transmission 589 of voice guidance. In response to the operation instruction, the voice synthesizer 14 sends out the voice guidance 590. At this time, the voice guidance is, for example, “The phone you are using is used for fraud, as in the operation instruction 4 of FIG. It is certified as “phone”. The voice guidance may be transmitted only once, a preset number of times, a preset time, or repeatedly until the caller goes on-hook. When the voice guidance transmission is finished, the call connection control unit 11 instructs the call connection processing unit 12 to disconnect the call, and transmits a call disconnection notification 592 to the device control unit 15. In response to this, the device controller 15 issues an operation stop instruction 593 to the speech synthesizer 14 to complete the processing.

FIG. 26 is an example of a sequence diagram in the case where the result of determination in process A2 (620) is a connection permission number. In the process A2 (620), after the next process is set to normally connect the call, the call connection control unit 11 instructs the call connection processing unit 12 to secure a call path with the calling telephone 46 and to call the incoming telephone 40. (594). The call connection processing unit 12 secures the communication path of the calling telephone 46 (595), and then calls the mobile telephone by securing the communication path with the incoming telephone 40 (596). When the off-hook is performed, the off-hook information is notified to the call connection control unit 11 (597), and the call connection control unit 11 that has detected the off-hook information instructs the call connection processing unit 12 to establish a call connection between the calling telephone 46 and the incoming telephone 40. (598), a call between the calling telephone 46 and the incoming telephone 40 is established (599).

FIG. 27 is the voice guidance transmitted in the process 823 among the voice guidance used in the description of FIG. 18. “When it is determined whether the current phone call is a fraud or not a fraud, It is a figure which shows the example of the sequence which showed the operation | movement by the detection of the special telephone number XYZ for receiving the report from a service subscriber with respect to "Please inform XYZ." Special phone number XYZ is a common phone number used to report to fraud countermeasure service subscribers whether fraud really occurred or whether it was not actually caused by misrecognition of the fraud countermeasure device . In this example, XYZ three-digit numbers are assumed for simplification, but in actual operation, any number of digits may be used according to the operation mode. The operation using the special phone number XYZ can be performed on the subscriber phone receiving the fraud countermeasure service itself or on the broadcast number that is a relative or relative phone number registered in advance by the subscriber receiving the fraud countermeasure service. It can be done only from the corresponding telephone. This is because, if the operation can be performed from any telephone number, the criminal side may operate and perform the crime.
This process operates when the call connection control unit 11 detects the call signal (899) of the telephone subscriber, and the call connection control unit 11 and the device control unit 15 or the call connection control unit 11 and the device control unit. 15 and the call connection control unit of the other fraud countermeasure device recognize the report contents from the filer in conjunction. In this process, the process of the call connection control unit 11 is composed of the process F1 (900), the process F2 (920), the process F3 (930), and the process F4 (990), and the process of the device control unit 15 is the process G1 ( 970), process G2 (980), and process G3 (940), and the process of the call connection control unit of the other anti-fraud device 2 includes process F0 (960) and process F4 (990) Details of each process will be described below. Note that FIG. 27 illustrates branching and notification processing, which will be described below together with the above processing.

  FIG. 28 is a diagram illustrating an example of operation of processing F1 (900) in FIG. Process F1 (900) is an operation executed by the call connection control unit 11. First, when the special number XYZ notified by the call control line 35 or 37 is received 901, the calling telephone number (the telephone number of the calling telephone). ) Is determined 902 whether or not the phone exists under its own device. This is performed by referring to the subscriber database that manages the telephones under its own device as shown in FIG. In the case of a call from a telephone not under the control of the own device, a connection request is received from another countermeasure device. First, an example of a call originating from a telephone under its own device will be described. The call connection control unit 11 stores the calling telephone number 903, and then inquires 904 the subscriber number area 130 of the service subscriber database 100. . Here, if the calling telephone number is in the subscriber number area 130, it is found that the subscriber is a fraud countermeasure service subscriber (905). If the calling telephone number is a fraud countermeasure service subscriber, the variable υ is defined and 1 is set as an initial value, and the subscriber telephone number referred to in FIG. 4 in the character array “subscriber [υ]”. A shim 440 corresponding to 420 is set, a variable ρ is defined, 0 is set as an initial value, and the process proceeds to process F2 described later. If the calling telephone number is not a fraud countermeasure service subscriber (905), the call connection control unit 11 may be a service subscriber because the calling telephone number may be a broadcaster of the fraud countermeasure service subscriber. A process of inquiring (906) the area of the broadcast number 1 (151) to the broadcast number L (15L) in the database 100 by the caller telephone number is performed. Subsequently, four variables λ, μ, υ, and ρ are defined, and initial values are set to 0 for the three variables λ, μ, and υ, and initial values are set to 1 for ρ. Here, λ is used for the horizontal query of the broadcast number area of the service subscriber database 100 of FIG. 2, and μ is used for the vertical query of the broadcast number area of the service subscriber database 100 of FIG. . Next, (λ + 1) is stored 908 in λ, and (μ + 1) is stored 909 in μ, and the broadcast number of the μth broadcaster in the λth service subscriber is set to data [λ] [ μ] is set 910. If this data [λ] [μ] is the same as that of the calling telephone number, (ν + 1) is stored in the variable υ to define the character array data “subscriber [υ]”. 4 is set to the corresponding subscriber data 440, the telephone number of the λth subscriber is stored in the numerical array data “subscriber number [υ]” (914), and the processing returns to step 908. Repeat the process. The repeated processing is performed in order to extract all possibilities because the broadcaster may be a broadcaster of a plurality of service subscribers. In process 911, if data [λ] [μ] is different from the calling telephone number, μ and L are compared 912, and the process returns to process 909 until μ reaches L. If μ reaches L, λ and K are compared 913, and the processing returns to processing 908 until λ reaches K. When μ reaches L and λ reaches K, the value of υ is seen. If ν is not 0, that is, if it can be determined that the report is from the broadcaster, processing F2 (920) If υ is 0, that is, if there is no calling telephone number in the broadcast number of the service subscriber database in the own apparatus, the process proceeds to F3 (940).

FIG. 29 is a diagram showing an example of the flow of processing when the outgoing telephone number of the special number XYZ is a broadcast number in FIG. In this process, the call connection control unit 11 and the device control unit 15 operate in cooperation with each other and include a process F2 (920) and a process G1 (970). First, the processing F2 (920) will be described. As shown in the processing F1 (900) of FIG. 25, the calling telephone number is present in the broadcast number of the service subscriber database 100 in its own apparatus. Upon detection, the call connection control unit 11 instructs the call connection processing unit 12 to connect the outgoing telephone and the voice recognition unit 13 and to connect the outgoing telephone and the voice synthesis unit 14 to the device control unit. A notification 5 as shown in FIG. Thereafter, if the notification 6 is returned from the apparatus control unit 15 (923), the process proceeds to process F3 (930), and if the notification 6 is not returned, the process proceeds to process 4 (990).
Next, processing G1 (970) will be described. Upon receiving a notification from the call connection control unit 11, the device control unit 15 transmits 971 the operation instruction 3 shown in FIG. 14 to the voice recognition unit 13. Thereafter, the apparatus control unit 15 defines a variable ξ and sets 972 to an initial value of 0. In the above-described process F2 (920), there are one or more sender telephone numbers as broadcast numbers, and the variable ξ is an integer value between 1 and υ. The device control unit 15 notifies the operation instruction 8 as shown in FIG. At this time, the speech synthesizer 14 sends out a speech guidance such as “This is a receipt of a fraud report using a telephone” according to the table of FIG. 32. Subsequently, the apparatus control unit 15 stores (ξ + 1) in ξ, and uses the character array “subscriber [ξ]” as name information of the target service subscriber as additional information of the operation instruction 9 shown in FIG. For example, referring to FIG. 4 and FIG. 32, the voice synthesizing unit 14 is notified, and voice guidance is transmitted with a content such as “Does it relate to <Hiroshi Takahashi>”? Waiting for the voice input from the caller to this voice guidance, if the answer is a positive answer to the question (976), it is a declaration for the current “subscriber [ξ]” Then, the process proceeds to process G3 (940). If the answer from the caller is not an affirmative answer, it is determined whether or not ξ has reached υ (977). If ξ has not reached υ, the process returns to step 974 to repeat the process. Do. Read the value of ρ when ξ reaches υ, and if the value of ρ is 0 (978), the caller is a service subscriber but a declaration for another service subscriber rather than a declaration for the principal Therefore, the process returns to the process 906 (circle numeral 2 in the figure) in FIG. If the value of ρ is not 0, there is a possibility that it is not a report for the service subscriber under its own device but a report for a service subscriber accommodated under another fraud countermeasure device, so the call connection control unit 11 The notification 6 is transmitted 979 including “1: other device inquiry” in the additional information, and the process proceeds to processing G2 (980).

FIG. 30 shows an example of the flow of the process F3 (930) and process G2 (980) described in FIG. 29 and the process F0 (960) performed by the other fraud countermeasure device 2. In FIG. 30, the call connection control unit 11, the device control unit 15, and the call connection control unit in another fraud countermeasure device operate in cooperation.
First, processing F3 (930) will be described. This is processing of the call connection control unit 11 that has received the notification 6 of the additional information “1: other device inquiry” from the device control unit 15 in FIG. A connection instruction (931) for the calling phone and voice recognition unit 13 and the calling phone and voice synthesis unit 14 is issued to the processing unit 12. Subsequently, the call connection control unit 11 sends 932 a notification 6 including additional information “2: voice recognition input” to the device control unit 15. This process is for listening to who is making the report directly, since the process up to this point has not been able to identify who the report is about. On the other hand, the call connection control unit 11 performs the target person determination by voice recognition to check whether or not the calling telephone number matches the broadcast number for the service subscriber accommodated under the other fraud countermeasure device. Then, inter-device communication is performed with all other fraud countermeasure devices other than the device itself (933). Although this inter-device communication will be described later, as shown in FIG. 33, in the inter-device communication here, “3: XYZ special number inquiry” is transmitted as a command to all other devices. Among other devices, a response is returned from the device that has detected that the calling telephone number matches the broadcast number. In process F3 (930), the identification information of the other device that has returned the response. Remember. On the other hand, information on the telephone number to be reported by voice recognition instructed to the device control unit 15 is received, and the telephone number to be reported is stored. Based on the information from the other devices and the device control unit 15, the call connection control unit 11 communicates the command 6 in FIG. 33 to the fraud countermeasure device accommodating the service subscriber to be declared and issues a connection request. . After waiting for a response to the connection request, it is determined whether connection is possible 935, and if the connection is possible, the process is left to another device. When the connection is rejected, a notification 8 as shown in FIG. 10 is transmitted 936 to the device control unit 15 to detect a call disconnection 937, and then a notification 2 is transmitted to the device control unit 15 again 938. Complete.
Next, the process G2 will be described. First, upon receiving the notification 6 from the call connection control unit 11, the device control unit 15 transmits an operation instruction 3 as shown in FIG. 14 to the voice recognition unit 13 (981). Subsequently, the device control unit 15 transmits an operation instruction 11 as shown in FIG. At this time, the voice synthesizer 14 sends out voice guidance corresponding to an operation instruction 11 as shown in FIG. In response to the voice guidance, when the reporter inputs the telephone number of the target person by voice, the voice recognition unit 13 recognizes the voice and transmits it to the device control unit 15 so that the device control unit detects the target phone number 983. To do. The device control unit 15 transmits 984 a notification 7 to the call connection control unit 11 with the detected target telephone number as additional information as illustrated in FIG. After that, the device control unit 15 stops the operation of the voice recognition unit 13 985. If there is a notification 8 from the call connection control unit 11, the device control unit 15 transmits an operation instruction 10 as shown in FIG. (986). At this time, the voice synthesizer sends voice guidance such as the operation instruction 10 in FIG. Finally, the operation of the speech synthesizer is stopped 987 to complete the processing. In the processes 982 and 983, it is possible to input a telephone number by using a push button or a dial that has been familiar to the user. In this case, the PB reception function and the DP reception function installed in the voice recognition unit 13 are used. Further, it can be realized by changing the guidance content of the operation instruction 11 in FIG. 32 to “Please input the telephone number by voice, push button or dial”.
Next, processing F0 (960) will be described. This processing F0 is processing performed by a fraud countermeasure device that is separate from the fraud countermeasure devices described so far. When an XYZ special number query as shown in FIG. 33 is received from a fraud countermeasure device, the device searches for the sender telephone number included in the data in the broadcast number area of the service subscriber database 100. Here, if a broadcast number matching the caller telephone number is found, data 961 is used to return data 961 indicating that the caller telephone number has been found as a broadcast number. To do. If a telephone number that matches the caller telephone number is not found, the fact that it is not found in the data shown in FIG. 33 may be communicated, or no response may be made. Although the process is once completed here, a connection request may be received from the fraud countermeasure device that has requested the inquiry of the calling telephone number. In this case, whether or not connection is possible is determined 962 in accordance with the process F1 (900) of FIG. 28 described above, and if it is determined that connection is possible, the connection request source fraud countermeasure device is permitted to connect as shown in FIG. Is sent back to Step F4 (940).

FIG. 31 is a diagram showing an example of the flow of the processes F4 (990) and G3 (940) described in FIG. Process F4 (990) and process G3 (940) are processes executed by the call connection control unit 11 and the device control unit 15, respectively, and operate in cooperation with each other.
First, processing G3 (940) will be described. This processing is processing performed by the device control unit 15. The device control unit 15 transmits an operation instruction 3 as shown in FIG. 14 to the voice recognition unit 13 (941). The content of the declaration is recognized, and an operation instruction 12 as shown in FIG. 12 is transmitted to the speech synthesizer 14 (942). At this time, the voice synthesizer 14 sends out voice guidance as shown in FIG. 32 to obtain information on whether or not fraud has occurred. When the voice recognition result from the filer is a positive answer to the question, that is, whether there is a fraud (943), the device control unit 15 detects occurrence of fraud 944. Then, it notifies the call connection control unit 11 that a fraud has occurred using the notification 10 as shown in FIG. 10 (945). Subsequently, an operation instruction 13 such as that shown in FIG. Thereafter, upon receiving the notification 9 from the call connection control unit 11, the speech recognition unit 13 is stopped 948 and the speech synthesis unit 14 is stopped 949. If it is determined in the determination process 943 that the respondent's answer is not positive, the device control unit 15 detects 950 that no fraud has occurred and uses the notification 10 to the call connection control unit 11 to detect the fraud. Notify that it has not occurred (951). Further, the operation instruction 14 is transmitted to the speech synthesizer 14 (952). Thereafter, upon receiving the notification 9 from the call connection control unit 11, the speech recognition unit 13 is stopped 953 and the speech synthesis unit 14 is stopped 954. Finally, since it is determined that the target telephone number has not been fraudulent, the call log related to the target telephone number may be deleted 955 from the call log database to be described later. For example, the log may be left by moving it to another storage device.
Next, process F4 (990) will be described. This process is performed by the call connection control unit 11. The call connection control unit 11 acquires the data of the suspected number areas 191 to 19N corresponding to the subscriber number [ξ] from the service subscriber database 100 (991). The call connection control unit 11 transmits a notification 9 as shown in FIG. 10 to the device control unit 15 (992). If it is confirmed that no fraud has occurred (993, No), the call connection control unit 11 erases the data of the suspected number areas 191 to 19N corresponding to the subscriber number [ξ] from the service subscriber database (994). Thereafter, call disconnection is detected (995), and the process ends.

  FIG. 32 is an example of a table that summarizes the guidance sent out by the speech synthesizer, and is a continuation of FIG. The voice guidance group shown in FIG. 32 is related to the declaration of the presence or absence of fraud, and the usage is as shown in FIGS. In the content of the guidance, <subscriber data [ξ]> is a person name (shime data) extracted from the service subscriber database 100 by the call connection control unit 11.

FIG. 33 is a diagram illustrating an example of communication data used when communication is performed between a fraud countermeasure device and another fraud countermeasure device. The inter-device communication data 3000 includes a device ID area 3001 for storing an ID number unique to the own device that is the transmission source of the data, a command area 3002 for storing an instruction to be executed by another device, and the command Parameter type areas 3003, 3006, and 3009 indicating more detailed instructions for the above, data contents areas 3005, 3008, and 3011 for storing data necessary for executing the instructions, and the length of the data contents can be made variable. Thus, the data length areas 3004, 3007, and 3010 that define the length are configured.
A part of the method of using the data has already been briefly illustrated in FIG. 30, but an example will be described in detail here. In the process 933 of FIG. 30, inter-device communication is performed. This is communication for inquiring whether the telephone number of the reporter, that is, the caller, exists in the broadcast number area of the subscriber database 100 of another fraud countermeasure device. Referring to FIG. 33, the fraud countermeasure device stores the ID number of its own device in the device ID area 3001 as an arbitrary integer value, and instructs “3”, that is, an XYZ special number inquiry in the command area 3002. Data is stored, “5” is stored in the parameter type area 3003, that is, data instructing the search of the broadcast number shown below is stored, and “10” is stored in the data length area 3004 if the telephone number is, for example, 10 digits. In this case, for example, it is the first broadcast number of the second service subscriber in FIG. 2 in another device. Stores 0332579613 ", from region 3006 to 3011 to set the no information, concurrently delivers to an apparatus other than the self apparatus. When the distribution destination device performs a collation process according to the instruction and finds a broadcast number that matches the calling telephone number, the ID number of the own device and the command are directed toward the above-mentioned distribution source device ID number. “4: XYZ special number inquiry complete”, parameter type “5: broadcast number / suspected number”, data length “10”, and broadcaster number “0332596613” are transmitted as data contents (process 961).
Further, the processing 934 in FIG. 30 will be described. The device stores “6” in the command area 3002, that is, a call connection request, following the ID number of itself, and “9” in the parameter type region 3003, that is, the connection. The request is stored, “0” is stored in the data length area 3004, no data is set in the data content area 3005, and “8” is stored in the area 3006, that is, data indicating that the caller telephone number is indicated for migration. The number of digits of the telephone number is stored in the area 3007, the caller telephone number “0332557913” is stored in the area 3008, and no information is set in the areas 3009 to 3011. Data is communicated to the ID number of the device that responded to the inquiry command. In the fraud countermeasure device that has received the data, the received command is executed to determine whether or not the outgoing telephone number is connectable. When the connection is permitted, “6” is added to the command area 3002 following the ID number of the own device. “10”, that is, data indicating connection permission is stored in the parameter type area 3003, the number of digits of the telephone number “10” is stored in the area 3004, and the caller telephone number “0332597613” is stored in the area 3005. No data is set in 3011, and the data is transmitted to the device ID of the transmission source of the command data (process 962).

FIG. 34 is a diagram showing a configuration example of call log data created using voice during a call. The call log data is created in the call log database 16 and is shown in the form of a table in FIG. 34 for simplification of description, but the recording form may be any appropriate form.
In the call log table 160, the first to Kth service subscribers are sequentially arranged in the vertical direction as in the service subscriber database shown in FIG. In the horizontal direction of the call log table 160, an area 181 for storing the telephone number of the subscriber, an area 182 for storing the telephone number of a telephone call made to the subscriber telephone number, and the area 182 are stored. An area 183 for storing the transmission date and time of the telephone number to be transmitted; an area 184 for storing text data obtained by recognizing a call made between the outgoing call and the incoming call and converting the voice; and recording the call And an area 185 for storing information.
In the subscriber telephone number storage area 181, service subscriber telephone numbers corresponding to FIG. 2 are sequentially stored. Since each subscriber telephone number receives an incoming call from a plurality of telephone numbers, the caller telephone number area The caller phone numbers are stored in the order of date and time. For example, the first and second columns of the first subscriber are receiving calls from the same telephone number, but are arranged in time series like the data in the date and time area, and the authenticity of fraud described later Effective for simplification of judgment.
In the text information storage area, data obtained by converting the result recognized by the speech recognition unit 13 into text is recorded, and terms frequently used in fraud in the recognition result are processed in step 814 in FIG. As shown, it is emphasized with a special symbol such as “*”. In FIG. 34, as an example, the text information on the first line of the first subscriber is given “*” before and after as a term frequently used in fraud. In addition, “*” is added before and after “I am,” in the text information on the first line of the second subscriber. Thereby, it is effective for simplification of the authenticity determination of the fraud mentioned later and the detection of a new fraud trick.
The recorded information may be stored in a commonly used WAVE format file or the like and listened to by a music playback application used in a general music player or the like. The voice data is generally sampled digital data, but in FIG. 34 it is expressed in katakana.

FIG. 35 is a diagram illustrating an example of the operation of the fraud countermeasure device operation unit 20. This processing is processing of the device operation unit 20 in response to the warning notification from the device control unit 15 already described with reference to FIG. 18, FIG. 21, and FIG. The warning notification generated in FIGS. 18 and 21 is a warning that is generated when it is determined that the possibility of fraud is high during a call based on the result of the voice recognition processing. The warning notification generated at 31 is a warning generated upon receiving a report that fraud has occurred from the filer after the call ends, and this is called warning 2. In the process H (3200), first, as described above, the warning notification (3201) is received from the apparatus control unit 15, and the incoming number included in the notification is detected 3202, and the notification date and time is detected 3203. Next, it is determined 3204 whether the above-described warning type is warning notification 1 or warning notification 2, and if it is determined that the warning notification 1 is determined, the transmission of the target call included in the warning notification is performed. The telephone number is detected 3205, a message notifying that the warning 1 has occurred is displayed 3206 on the display, and a response 3209 from the operator is awaited. If it is determined that the warning type is the warning notification 2, the suspected telephone number group included in the warning notification is detected, and a message 3208 indicating that the warning 2 has occurred is displayed together with this, and the operator is displayed. Wait for a response 3209 from. Here, the calling telephone number described in the process 3205 is the calling telephone number of the telephone that is currently in a call, and the suspicion of fraud is extremely high in that one call. Further, the suspicious telephone number group described in the processing 3207 is a telephone that has been received for the service subscriber telephone specified in FIG. 28 to FIG. Refers to all of the caller ID columns corresponding to a single subscriber.
When the operator starts the operation of the device operation unit 20, the device operation unit 20 starts 3210 an application for displaying the contents of the call log database, which will be described later, and reads the corresponding information from the call log database 3211. Provide simple necessary information to scam experts.

  FIG. 36 is a diagram showing an example of display on the device operation unit 20 described with reference to FIG. This display screen 33 effectively displays the minimum necessary information from the call log table of FIG. 34, and displays the telephone number display area 331 of the service subscriber and the telephone number of the service subscriber. Calling telephone number display area 332, the date and time display area 333 of the call, the area 334 for displaying the voice recognition result of the call in text, and the call specified by the above-mentioned 331 to 333 When the operator recognizes that a new trick has occurred by looking inside the display area 334 and marking a new fraud term used in the trick A button 336 that allows you to extract new fraud terms by pressing on it, and a term that allows you to send guidance to encourage appropriate action against new tricks A button 337 for extracting new additional information by pressing the button, a button 338 for registering a term extracted with the buttons 336 and 337, and a call telephone number in the corresponding call can be determined to be fraud. And a button 339 for registering the calling telephone number as the confirmed fraud telephone number shown in FIG. This screen uses a pointer 330 or the like generally used on a personal computer, etc., and first clicks on the service subscriber, then clicks on the caller corresponding to the service subscriber, and further displays the caller's call date and time. By clicking, the corresponding call content is displayed in the display area 334. In the text in the display area 334, what is detected as a fraud term, that is, a word surrounded by “*” described with reference to FIG. 34 is highlighted with a wavy line. Here, words such as “I”, “I have a cold” and “I have a bad throat” are emphasized as fraudulent terms. An expert will determine from the contents written in the display area 334 whether or not it is a fraud.

  FIG. 37 is a diagram showing another example of a call on the screen display shown in FIG. In FIG. 37, another call for the same service subscriber as in FIG. 36 is instructed and the content of the call is displayed. In this example, the method of fraud is completely new, and there are only a few fraud terms with “ATM” underlined. An expert is asked for this content, and a pointer 330 is used to extract new scam terms. For example, the word “tax office” is marked and a new fraud term extraction button 336 is pressed. Similarly, “tax”, “return”, “as instructed”, and “manipulate” are extracted. The extracted new fraud terms are underlined. In addition, when extracting a term for creating a voice guidance that can prompt the service subscriber to take a more appropriate action for a new trick, the word “tax office” is marked and a new additional information extraction button 337 is extracted. Press. This will double underline the “Tax Office”. When the term registration button 338 is finally pressed, the words extracted so far are registered in each database.

  FIG. 38 is a diagram showing an example of the term registration process extracted in FIG. When the term registration button 348 is pressed, the extracted term group 35 is classified into a new fraud term 351 and new additional information 352. First, for the new fraud term, the voice for speech recognition is extracted from the extracted term 353 which is text data. Data is created and stored in the term conversion area 354. For new additional information, a sentence is created using the extracted term, and voice data obtained by converting the sentence into voice guidance is stored in the term conversion area 354. In this example, five terms 355 extracted as new fraud terms are sent to the recognition speech database unit 17 as indicated by arrows, and are additionally registered sequentially in the tail 1501 of the database 1500 and subsequent speech recognition. Used for processing and fraud term extraction. On the other hand, the voice guidance 356 created from the new additional information is sent to the synthesizing voice database unit 18 as indicated by an arrow, and additionally registered in the tail 1301 of the database 1300 and used as voice guidance thereafter.

FIG. 39 is a diagram illustrating an example in which the content described in FIG. 38 is distributed to another fraud countermeasure device. In FIG. 38, the database update is performed in the fraud countermeasure device that was processed when the fraud occurred. Similar fraud crimes may occur in various parts of the country and spread throughout the country. All of the devices need to be in a state that can counter crimes as well.
The data 3000 shown in FIG. 39 is in the data format used in the inter-device communication described with reference to FIG. If the example shown in FIG. 37 and FIG. 38 is continued and described, it is stored in the area 3001 as its own device ID, here “0001”, and in the area 3002, “1”, that is, a database change request. The area 3003 stores “1”, that is, data instructing addition of the confirmed fraud number, and the area 3004 stores “11”, that is, data indicating that the data length is 11. The area 3005 stores the eleven-digit confirmed fraud number “09067953421”, and the area 3006 contains “3”, that is, data indicating that the new fraud term is stored below. 3007 stores “5”, that is, data indicating that there are five data in the next area. Contains five pieces of data for speech recognition “Zaisho”, “Zaikin”, “Henkan”, “Washishinoshidoori”, “Sosashite”, and “4”, that is, new additional information is stored in the area 3009 below. The area 3010 is “1”, that is, data indicating that one data is stored in the next area, and the area 3011 is one piece of voice guidance data. Stores “Contact your local tax office”. Each fraud countermeasure apparatus that has received the data 3000 executes storage processing in the database in the apparatus according to the command in the area 3002 and the parameter types in the areas 3003, 3006, and 3009. First, the confirmed fraud number stored in the area 3005 is additionally registered at the end of the confirmed fraud telephone number database 300 of the fraud countermeasure device as shown in FIG. 3, and the voice data stored in the areas 30081 to 30085 are The voice guidance data additionally registered in the tail 1502 of the recognition speech database 1500 corresponding to FIG. 15 and stored in the area 3011 is additionally registered in the tail 1302 of the synthesis speech database 1300 corresponding to FIG. Through the above processing, each fraud countermeasure device responds to a fraud crime of a new technique.

FIG. 40 is a diagram showing an example of a case where a certain fraudulent telephone is canceled with respect to the confirmed fraud number database 300 described in FIG. As described with reference to FIG. 3, the telephone number registered in the database 300 cannot be called to a fraud countermeasure service subscription telephone. This indicates that the telephone number cannot be reused even if the contract of the telephone number is canceled. Therefore, since this will cause the phone number to be exhausted, it is necessary to prepare means for making the phone number not a fraud confirmed phone number when the contract of the phone number is canceled.
This means is assumed to be performed by communication from the operation center 50 that manages and manages the contract status to the fraud countermeasure device. Here, an example will be described in which the inter-device communication data shown in FIG. 33 described above is transmitted from the operation center to each fraud countermeasure device. Referring to FIG. 33, the operation center 50 stores its own apparatus ID in the area 3001 of the inter-apparatus communication data 3000, stores “1”, that is, data indicating a database change request in the area 3002, and stores “2” in the area 3003. ", That is, data for instructing deletion of the confirmed fraud number is stored," 11 ", that is, the number of digits of the telephone number used in this example is stored in the area 3004, and the telephone number for which the contract is canceled (in this example, the area 3005 3 is stored, and no data is set in the areas 3006 to 3011 and transmitted to each fraud countermeasure device. Each fraud countermeasure apparatus receives the data and searches the confirmed fraudulent telephone number database 300 for the telephone number “090227996084” in the area 3005 according to the command and the parameter type. In FIG. 3, the telephone number 352 exists in the confirmed fraud phone number 3, and the fraud countermeasure device deletes this data and shifts each data in the database. The telephone number in the number 4 is shifted to the confirmed fraud phone number 3, and the data 353 as shown in FIG. 40 becomes a database stored in the confirmed fraud phone number 3. As a result, the telephone number “090227996084” is no longer the telephone number used for fraud and can be reused.

  FIG. 41 is a diagram illustrating an example of a contract method using a telephone and a processing sequence for changing contract contents to a fraud countermeasure service using a telephone. The registration application for the fraud countermeasure service using the telephone may be made by submitting a paper document. However, it can be automatically performed using the telephone by the processes shown in FIGS. In order to ensure safety, this automatic registration process can be performed only from a telephone that enjoys the service. This processing is triggered by detecting a call signal (3799) of a special telephone number, for example, a number such as UVW, from a telephone subscriber. In this process, the call connection control unit 11 and the device control unit 15 work together, the call connection control unit 11 operates from the processing S1 to the processing S9, and the device control unit 15 operates from the processing J1 to the processing J9. . Hereinafter, each process will be described. Note that FIG. 41 illustrates branching and notification processing, which will be described below together with the above processing. In addition, the reply contents from the following telephone subscribers can be judged by voice recognition.

FIG. 42 is a diagram illustrating an example of the flow of the process S1 (3810) executed by the call connection control unit 11 and the process J1 (3800) executed by the device control unit 15. As shown in FIG. 42, this processing is performed in cooperation with the call connection control unit 11 and the device control unit 15. First, the processing S1 (3810) will be described. The processing is started when the call connection control unit 11 detects (3811) that a telephone number for changing the registered contents, for example, the special number UVW is transmitted. The call connection control unit 11 detects 3812 the telephone number of the telephone that has transmitted the special number UVW, and connects the calling telephone and the voice recognition unit 13 to the call connection processing unit 12 and the calling telephone and the voice synthesis unit 14. Is instructed 3813. Next, the call connection control unit 11 inquires about the calling telephone number in the area of the subscriber telephone number 130 of the subscriber database 100. As a result, if the calling telephone number exists, the process proceeds to process S2 (3920) described later. If the calling telephone number is not in the area of the subscriber telephone number 130, the call connection control unit 11 determines that the call is from a person who may make a new contract, and the call connection control unit 11 sends it to the device control unit 15 as shown in FIG. The notification content “1” of the notification 12 shown, that is, data indicating contract confirmation is transmitted. The call connection control unit 11 monitors whether the call disconnection occurs until the device control unit 15 executes the process J1 (3800) and returns a response, and detects the occurrence of the call disconnection. Then, a call disconnection process 3819 is performed to complete the process.
Next, processing J1 (3800) will be described. Upon receiving the notification 12, the device control unit 15 transmits an operation instruction 4 to the voice recognition unit 13 as shown in FIG. 14 (3801), as shown in FIG. An operation instruction 15 is transmitted to the voice synthesizer 14 (3802), and voice guidance is transmitted. The voice guidance at this time is like the operation instruction 15 in FIG. 54, and waits for a response from the contract applicant. The input voice from the contract applicant is recognized, and it is determined 3803 whether or not the recognition result is an affirmative answer. If the answer is affirmative, the process proceeds to process J2 (3900). If it is determined that the answer is not positive, as shown in FIG. 53, the operation instruction 16 is transmitted to the speech synthesizer 14 as shown in FIG. 53 (3805), and voice guidance is transmitted. The voice guidance transmitted at this time has the contents as shown in the operation instruction 16 of FIG. 54, and the device control unit 15 transmits a notification 11 as shown in FIG. 10 to the call connection control unit 11 (3806). The call disconnection is requested, the speech recognition unit 13 is stopped 3807, the speech synthesis unit 14 is stopped 3808, and the process is completed.

FIG. 43 is a diagram showing an example of the flow of the process S2 (3920) executed by the call connection control unit 11 and the process J2 (3900) executed by the device control unit 15. As shown in FIG. 43, this process is performed in cooperation with the call connection control unit 11 and the device control unit 15. First, the process J2 (3900) will be described. In the process 3803 in FIG. When it is determined that the answer is affirmative, the apparatus control unit 15 detects the result 3901 and communicates 3902 the notification content “2” of the notification 12 in FIG. 10, that is, the new contract to the call connection control unit 11. When the device control unit 15 waits for a response from the call connection control unit 11 and receives the notification 12, the device control unit 15 transmits the operation instruction 17 shown in FIG. At this time, as shown in the operation instruction 17 of FIG. 54, the voice guidance is for whether or not to continue registration, and asks the contract applicant. If the response from the contract applicant is such a content as to end the process (3904), the process proceeds to process 3906. If the question is affirmative, the process proceeds to the process 4003 in FIG. 44 (the connection is indicated by the circled numeral 3 in the figure). If the response from the contract applicant is not positive with respect to the question, an operation instruction 18 as shown in FIG. 53 is transmitted to the voice synthesizer 14 and voice guidance is transmitted. The voice guidance transmitted at this time has the contents as shown in the operation instruction 18 in FIG. After that, the device control unit 15 transmits 3907 a call disconnection request of the notification 11 as shown in FIG. 10 to the call connection control unit 11, stops the speech synthesis unit 14, and stops the speech recognition unit 13 3909. To finish the process.
Next, the processing S2 will be described. The call connection control unit 11 receives the notification 12 from the device control unit 15 and receives the notification 12 from the device control unit 15, and the (K + 1) -th after the K at the tail end of the service subscriber database 100 The outgoing telephone number is registered 3921. After registration, the fact that the calling telephone number is newly contracted is transmitted to the operation center 50 to be managed. After completing the above processing, the call connection control unit 11 transmits the notification content “3” of the notification 12 as shown in FIG. Thereafter, the call disconnection is detected, and the call disconnection process 3924 is executed to complete the process.

FIG. 44 is a diagram showing an example of the flow of the process S3 (4020) executed by the call connection control unit 11 and the process J3 (4000) executed by the apparatus control unit 15. This process is performed by the call connection control unit 11 that moves when it is determined in the determination process 3815 described above with reference to FIG. 42 that the telephone number that has transmitted the special telephone number UVW is already subscribed to the fraud countermeasure service. This relates to the process S3 (4020) and the process J3 of the apparatus control unit 15 associated therewith. First, the processing S3 (4020) will be described. Upon receiving the determination processing 3815 in FIG. 42, the call connection control unit 11 notifies the device control unit 15 of information indicating registration change as indicated by the notification number 13 in FIG. To do. Thereafter, after waiting for call disconnection detection 4022, call disconnection processing 4023 is performed, and the process proceeds to step S4 (4110).
Next, the processing J3 will be described. Upon receiving the notification 13 from the call connection control unit 11, the device control unit 15 transmits the operation instruction 4 as shown in FIG. An operation instruction 21 as shown in FIG. The voice guidance transmitted at this time has contents as shown in the operation instruction 21 of FIG. Subsequently, the device control unit 15 transmits an operation instruction 22 as shown in FIG. 53 to the speech synthesis unit 14. The voice guidance transmitted at this time has a content prompting selection of registered content as shown in the operation instruction 22 in FIG. When the reply of the contract change applicant to the question by the voice guidance is a result indicating the end (4004), the process proceeds to process J5 (4200). If the result is a request to register a broadcaster, not the end (4005), the apparatus control unit 15 defines a variable σ, sets the initial value to 1, and proceeds to processing J6 (4300). . If it is not a broadcaster registration request but a result requesting registration of a connection authorized person (4006), the apparatus control unit 15 defines a variable σ, sets 2 as an initial value, and performs process J6 (4300). Migrate to Note that the variable σ is a later process. When σ is 1, it means that it is related to the broadcaster number, and when σ is not 1 (when σ is 2), it means that the connection is authorized. It will be. If none of the determination processes 4004 to 4006, the apparatus control unit 15 transmits the operation instruction 19 shown in FIG. The voice guidance transmitted at this time has a content for confirming whether or not it is desired to cancel the service contract as in the operation instruction 19 shown in FIG. 54 (4007). If it is a result indicating the end (4008), the process proceeds to process J5 (4200), and if it is not the end and the answer is not positive, the process also proceeds to process J5 (4200). When the answer is affirmative (when the answer is to cancel the contract), the device control unit 15 notifies the call connection control unit 11 as shown in the notification 12 of FIG. The operation instruction 20 shown in FIG. The voice guidance transmitted at this time has a content like the operation instruction 20 shown in FIG. 54. Thereafter, the call connection control 11 is notified 4012 of the call disconnection request notification 11, and the operation of the voice recognition unit 13 is stopped 4013. Then, the operation of the speech synthesizer 14 is stopped 4014, and the process proceeds to process J4 (4100).

FIG. 45 is a diagram showing an example of the flow of the process S4 (4110) executed by the call connection control unit 11 and the process J4 (4100) executed by the device control unit 15. This process is a process subsequent to FIG. 44 described above. First, the process S4 (4110) will be described. The contract cancellation notice from the apparatus control unit 15 has already been received, and the calling telephone number is sent to the operation center 50. It communicates that the contract of the fraud prevention service has been canceled (4111). In this case, using the inter-device communication data 3000 as shown in FIG. 33, the command is “7”, the parameter type is “17”, and the outgoing telephone number is added to communicate. Next, the call connection control device 11 deletes the item relating to the calling telephone number from the service subscriber database 100 in the own device 4112 and calls the device control unit 15 to cancel the contract using the notification 7 shown in FIG. The number is notified 4113 to complete the processing.
In process J4 (4100), in response to the notification 7 from the call connection control unit 11, call log data relating to the corresponding telephone number is deleted 4101 to complete the process.

FIG. 46 is a diagram showing an example of the flow of the process S5 (4210) executed by the call connection control unit 11 and the process J5 (4200) executed by the device control unit 15. This processing is shifted from the determination processing 4004, 4008 and 4009 in FIG. First, the process J5 (4200) will be described. When the immediately preceding operation is the operation instruction 22 or 23 of the speech synthesizer 14 (4201), the apparatus control unit 15 sends the operation instruction 31 shown in FIG. Tell (4202). The voice guidance transmitted at this time has a content like the operation instruction 31 shown in FIG. If the previous operation is not the operation instruction 22 or 23 of the speech synthesizer 14 (4201), the apparatus control unit 15 transmits the operation instruction 32 shown in FIG. 53 to the speech synthesizer 14 (4203). Subsequently, the device control unit 15 requests the call connection control unit 11 to disconnect the call 411 with the notification 11, stops the operation of the speech recognition unit 13 4205, stops the operation of the speech synthesis unit 14 4206, and performs processing. Complete.
The process S5 (4210) will be described. The call connection control unit 11 detects 4211 a call disconnection request from the apparatus control unit 15, performs a call disconnection process 4212, and completes the process.

  FIG. 47 is a diagram showing an example of the flow of the process J6 (4300) executed by the apparatus control unit 15. As described above with reference to FIG. 44, the process J6 (4300) shifts to the case where the contract change applicant wishes to register the broadcaster or the connection permitter in the determination processes 4005 and 4006. In process J6, the apparatus control unit 15 first determines the value of the variable σ, and if σ is 1, it determines that it is a change in the broadcaster number registration, and σ is not 1 (σ is 2). ), It is determined 4301 that it is a change in registration of the authorized person number. First, when σ is 1, the device controller 15 sends the operation instruction 23 shown in FIG. 53 to the voice synthesizer 14 including additional information “1”, that is, the voice guidance to be sent including the word “dough shaving”. (4302). When σ is not 1 (σ is 2), the apparatus control unit 15 adds the operation instruction 23 shown in FIG. 49 to the voice synthesis unit 14 as additional information “2”, that is, “set-up time” in the voice guidance to be transmitted. Tell them to send out the word (4302). The voice guidance at the time of the processes 4302 and 4303 has the contents as shown in the operation instruction 23 of FIG. 54. Depending on the value of the additional information of the operation instruction 23, either “registration number registration addition or registration deletion” "Do you want to add or delete registration of connection permission number?" When the response from the contract change applicant to the question made by the voice guidance is the content indicating the end of the process (4304), the process proceeds to the process J5 (4200) in FIG. If the response from the contract change applicant is not the content indicating the end of the process but the content requesting registration addition (4305), the apparatus control unit 15 defines the variable τ and sets its initial value to 1 (4306). The process proceeds to process J7 (4400). If the response from the contract change applicant is not a content requesting registration addition but a content requesting registration deletion (4307), the apparatus control unit 15 defines a variable τ and sets its initial value to 2 (4308). The process proceeds to process J7 (4400). If it is neither, the process proceeds to process J9 (4600).

  FIG. 48 is a diagram showing an example of the flow of the process J7 (4400) executed by the apparatus control unit 15. As described above with reference to FIG. 47, the process J7 (4400) is shifted to the case where the contract change applicant desires to register the broadcaster or the connection permitter in the determination processes 4305 and 4306. In process J7 (4400), the device control unit 15 first transmits an operation instruction 4 as shown in FIG. 14 to the speech recognition unit 13 (4401), and transmits an operation instruction 25 as shown in FIG. 53 to the speech synthesis unit 14. (4402). Here, for the operation instruction 25, two values are added as additional information. First, the first value is “1” or “2”, and these are “Douhoubango” or “Setsuzo Kokushashabangou” as voices, respectively. The second value is “3” or “4”, which indicates whether “Simei” or “Denwabango” is to be sent as a voice. In process 4402, the voice guidance including σ and “3” already set in process J3 (4000) in FIG. In this voice guidance, it is expected that the person name is input from the contract change applicant, but when a recognition result indicating the end of the process is obtained as an input (4403), the process proceeds to process J5 (4200). The recognition result does not indicate the end, but when the voice input is interrupted, it is determined that the input from the contract change applicant has been completed 4404, the character array name is defined, and the character representing the name recognized in the name The column is stored 4405. Next, the device control unit 15 transmits the operation instruction 25 to the speech synthesis unit 14 including the value of σ and “4” as additional information (4406). In response to the voice guidance transmitted here, it is expected that a telephone number is input from the contract change applicant, but if a recognition result indicating the end of the process is obtained as input (4407), process J5 (4200) ) The recognition result does not indicate the end, but when the voice input is interrupted, it is determined that the input from the contract change applicant has been completed 4404, the numeric array telno is defined, and the telephone number recognized by telno is represented. A numeric string is stored 4409. With respect to the name and telephone number recognized in the processing so far, if τ is 1, additional processing will be performed from the result obtained in the determination processing 4305 of FIG. 47 described above, and processing proceeds to processing J8 (4500). If τ is not 1, that is, τ is 2, the deletion process is performed from the result obtained in the determination process 4307 of FIG. 47 described above, and the process proceeds to process J9 (4600). In the processes 4406 and 4407, it is possible to input a telephone number by using a push button or dial, which has been used so far. In that case, the PB reception function and the DP reception function installed in the voice recognition unit 13 are used. Also, it can be realized by changing the guidance content of the operation instruction 25 in FIG. 55 to “Please input <phone number> by voice, push button or dial”.

FIG. 49 is a diagram showing an example of the flow of the process S6 (4520) executed by the call connection control unit 11 and the process J8 (4500) executed by the device control unit 15. This process is executed when τ is 1 in the process 4410 of FIG. 48, that is, in the process 4305 of FIG. 47, the registration change applicant desires the registration addition process. First, processing J8 (4500) will be described. The device control unit 15 notifies the call connection control unit 11 of the notification 14 shown in FIG. 10 with the notification content “1”, that is, the subscriber registration confirmation and the telephone number and name recognized in the additional information. And 450 including the values of σ and σ. Subsequently, the notification shown in the operation instruction 26 in FIG. 53 is transmitted to the speech synthesizer 14 including the name storing the recognized name and the telno storing the recognized telephone number (4502). The voice guidance transmitted at this time has contents such as “Acknowledged name Hitakachi Taro phone number Hachirokuichiiniinisan” like the operation instruction 26 in FIG. When the registration change applicant's response to the voice guidance question is the content indicating the end (4503), the process proceeds to process J5 (4200). If the response does not indicate the end and is not an affirmative answer (4504), the process proceeds to processing 4402 in FIG. 48 (circled number 4 in the figure indicates connection). If it is determined that the response is affirmative, the device control unit 15 notifies the speech synthesizer 14 of the notification shown in the operation instruction 27 of FIG. 53 by using the name storing the recognized name and the telno storing the recognized telephone number. (4505). The voice guidance transmitted here is a standby request as shown by the operation instruction 27 in FIG. Thereafter, the notification 14 from the call connection control unit 11 is waited. When the notification 14 from the call connection control 11 includes “3” as a parameter (4506), the device control unit 15 sends the voice synthesis unit 14 to FIG. The recognized name information name, the recognized telephone number information telno, the value of σ obtained by the processing so far, and τ = 1 obtained by the processing so far, such as the operation instruction 28 shown in FIG. The value is transmitted as additional information (4507). The voice guidance transmitted at this time is as shown in the operation instruction 28 of FIG. 55, and has a content such as “I have received the name“ Hitachi Taro ”and“ No. Subsequently, the apparatus control unit 15 transmits an operation instruction 24 shown in FIG. 53 to the speech synthesis unit 14 (4508). The voice guidance transmitted at this time is for confirming the continuation of the processing as shown in the operation instruction 24 of FIG. If the contract change applicant's answer to the voice guidance question indicates the end (4509), the process proceeds to process J5 (4200). If the answer does not indicate the end but is not affirmative (4510), the process proceeds to process J5 (4200). If the answer is affirmative, the process proceeds to a process 4003 in FIG. In the processing 4506, when the parameter of the notification 14 is not 3, the device control unit 15 transmits the operation instruction 29 shown in FIG. 53 to the speech synthesis unit 14 (4511). The voice guidance transmitted at this time is as shown in the operation instruction 29 in FIG. 55, and then the process proceeds to the process 4402 in FIG. 48 (connection is indicated by a circled number 4 in the figure) to prompt the contract change applicant to input. .
Next, the processing S6 (4520) will be described. The call connection control unit 11 receives the notification 14 from the device control unit 15, and responds to the telephone number data telno included in the notification 14 with its own device or another fraud countermeasure device. It is checked whether the telephone number exists in the telephone network with reference to the subscriber database (4521). At this time, when referring to the subscriber database of another device, the inter-device communication data shown in FIG. 33 is set to “5” for the command, “6” and “7” for the parameter type, and the telephone number and name recognized in the data contents. May be used. This process includes adding an incorrect phone number that does not exist, adding an incorrect registration due to an error in the contract change applicant, or adding an incorrect registration due to an incorrect recognition of the voice recognition function of the fraud countermeasure device. This is done to avoid this. When it is confirmed that the subscriber exists by this process (4522), the call connection control unit 11 gives the parameter 4 to the notification 14 and notifies the device control unit 15 as shown in FIG. The process proceeds to step S8 (4700). When it is determined in the determination process 4522 that the subscriber does not exist, the call connection control unit 11 assigns the parameter: 4 to the notification 14 as shown in FIG. Complete.

FIG. 50 is a diagram showing an example of the flow of the process S7 (4620) executed by the call connection control unit 11 and the process J9 (4600) executed by the device control unit 15. This process is executed when τ is not 1 in the process 4410 of FIG. 48, that is, in the process 4307 of FIG. 47, the registration change applicant desires the registration deletion process. First, processing J9 (4600) will be described. The device control unit 15 notifies the call connection control unit 11 of the notification 14 shown in FIG. A notification 4601 including the value of σ is sent. Subsequently, the notification shown in the operation instruction 26 in FIG. 53 is transmitted to the speech synthesizer 14 including the name storing the recognized name and the telno storing the recognized telephone number (4602). The voice guidance transmitted at this time has contents such as “Acknowledged name Hitakachi Taro phone number Hachirokuichiiniinisan” like the operation instruction 26 in FIG. If the registration change applicant's response to the voice guidance question is the content indicating the end (4603), the process proceeds to process J5 (4200). If the response does not indicate the end and is not an affirmative answer (4604), the process proceeds to the process 4402 in FIG. 48 (indicated by a circled number 4 in the figure). If it is determined that the response is affirmative, the device control unit 15 notifies the speech synthesizer 14 of the notification shown in the operation instruction 27 of FIG. (4605). The voice guidance transmitted here is a standby request as shown by the operation instruction 27 in FIG. Thereafter, the notification 14 from the call connection control unit 11 is waited. When the notification 14 from the call connection control 11 includes “3” as a parameter (4606), the apparatus control unit 15 sends the voice synthesis unit 14 to FIG. The recognized name information name, the recognized telephone number information telno, the value of σ obtained by the processing so far, and τ = 2 obtained by the processing so far, such as the operation instruction 28 shown in FIG. The value is transmitted as additional information (4607). The voice guidance transmitted at this time is as shown in the operation instruction 28 of FIG. 55, and has a content such as “I have made the name Hitachitaro phone number Hachirokuichiichiiniinisan.” Subsequently, the apparatus control unit 15 transmits the operation instruction 24 shown in FIG. 53 to the voice synthesis unit 14 (4608). The voice guidance transmitted at this time is for confirming the continuation of the processing as shown in the operation instruction 24 of FIG. If the reply of the contract change applicant to this voice guidance question indicates the end (4609), the process proceeds to process J5 (4200). If the answer does not indicate the end but is not affirmative (4610), the process proceeds to process J5 (4200). If the answer is affirmative, the process proceeds to a process 4003 in FIG. In the process 4606, when the parameter of the notification 14 is not 3, the device control unit 15 transmits the operation instruction 29 shown in FIG. 53 to the speech synthesis unit 14 (4611). The voice guidance transmitted at this time is as shown in the operation instruction 29 in FIG. 55, and then the process proceeds to the process 4402 in FIG. 48 (connection is indicated by a circled number 4 in the figure) to prompt the contract change applicant to input. .
Next, processing S7 (4620) will be described. The call connection control unit 11 receives the notification 14 from the device control unit 15, and is used by the contract change applicant in the service subscriber database 100 of the own device. In the area corresponding to the calling telephone number, the telephone number data telno included in the notification 14 is searched to check whether it exists (4621). When it is confirmed by this processing that the telephone number exists (4622), the call connection control unit 11 gives a parameter 4 to the notification 14 to the device control unit 15 as shown in FIG. The process proceeds to step S9 (4800). When it is determined in the determination process 4622 that the telephone number does not exist, the call connection control unit 11 assigns the parameter: 4 to the notification 14 and notifies the device control unit 15 as shown in FIG. Complete.

  FIG. 51 is a diagram showing an example of the flow of processing for the processing S8 (4700) executed by the call connection control unit 11. In the process S8 (4700), the call connection control unit 11 looks at the value of σ acquired in the process so far, and when σ is 1 (4701), it is a broadcast number registration addition process. Stores the (L + 1) th telephone number recognized by voice in the broadcast number area corresponding to the calling telephone number in the service subscriber database 100. When σ is not 1, that is, when σ is 2, connection permission number registration / addition processing is performed, so that the voice recognition is performed for the (M + 1) th connection permission number area corresponding to the calling telephone number in the service subscriber database 100. Stored phone number.

  FIG. 52 is a diagram showing an example of the flow of processing for the processing S9 (4800) executed by the call connection control unit 11. In the process S9 (4800), the call connection control unit 11 looks at the value of σ acquired in the process so far, and when σ is 1 (4801), it is a broadcast number registration deletion process. The broadcast number area corresponding to the calling telephone number in the service subscriber database 100 is searched, and the same telephone number as the recognized telephone number is extracted 4802. The telephone number is deleted 4803 from the extracted telephone number storage area, the data after the deleted storage area is padded 4804, the service subscriber database 100 is organized, and the process is completed. When σ is not 1, that is, when σ is 2 (4805), it is a connection permission number registration deletion process. Therefore, the connection permission number area corresponding to the calling telephone number in the service subscriber database 100 is searched and recognized. 4802 is extracted 4802 which is the same telephone number as the telephone number which has been selected. The phone number is deleted 4806 from the extracted phone number storage area, the data after the deleted storage area is left-justified 4807, the service subscriber database 100 is organized, and the process is completed.

  FIG. 53 is an example of a table that defines operation instructions given to the speech synthesizer 14 by the device control unit 15 and is an item that could not be described in FIG. 12 above. In particular, FIG. It represents an operation instruction related to the automatic registration process. The operation instruction data 770 is the same as that described with reference to FIG. In the additional information area 772 in this figure, as described with reference to FIGS. 42 to 50, by sending the voice guidance including the name and phone number recognized by voice, guidance that is easier to understand is provided to the caller. It is possible to provide.

  FIGS. 54 and 55 are examples of tables that define the operation in response to the operation instruction shown in FIG. 53 and the voice guidance to be sent out by the speech synthesizer 14 and are a series of FIGS. 13 and 32. In particular, FIGS. 54 and 55 show operation instructions related to the automatic registration process for the fraud countermeasure service described in FIG. 54 and 55, the part enclosed by “<” and “>” means that a character string or a numeric string given from the device control unit 15 is converted into voice data. Specifically, the voice guidance is as described in the description of FIGS. 47, 48, 49, and 50.

  56 to 61 are diagrams showing an implementation method in the case of using e-mail in a means for notifying service subscribers and broadcasters of information that calls attention after a call suspected of fraud. .

  FIG. 56 is a diagram showing an example of a network configuration when notifying information is notified by electronic mail. The fraud device countermeasure device 1 is connected to an IP (Internet Protocol) network such as the Internet or a mobile phone network 5200. The network 5200 is provided with a mail server 5201, which exchanges a mail transmission / reception protocol with the apparatus control unit 15 to deliver electronic mail.

FIG. 57 shows another form of the service subscriber database 100 when the alert information is notified by e-mail. In the database shown in FIG. 57, the information 130 regarding the service subscriber further includes an area 5300 for storing the mail address of the service subscriber. The e-mail address stored in this area is stored in the telephone subscriber data base shown in FIG. The call connection control unit 11 refers to and stores the mail address 450 of the service. For example, in the case of the second subscriber in FIG. 4, “1223hiro_yama_51@mail.ne.jp” is registered in the mail address area 450, and the call connection control unit 11 reads this data, and FIG. It is stored in the storage area 5301 shown.
For the broadcaster, both the telephone number and the mail address are mixed in the broadcast number area (151 to 15L). The method for adding the mail address registration of the broadcaster may be performed when it is confirmed whether or not there is a telephone subscriber that has been voice-recognized in the process 4521 of FIG. 49. Is stored in the last (L + 1) th of the broadcast number storage area of the service subscriber database 100 from the mail address area 450 of the telephone subscriber database 400 in the database unit 10. When a telephone subscriber that has been voice-recognized is accommodated in another device, it is only necessary to obtain a mail address using the inter-device communication data 3000 of FIG. 33. Specifically, since it cannot be described in FIG. In FIG. 61, the command is “5”, the parameter type is “18”, the inter-device communication data 3000 is transmitted to the other device, the return data is the command “5”, the parameter type is “19”, and the data content is e-mail. Get including the address. The acquired mail address data is stored in the service subscriber database 100 as, for example, a storage area 5302. When a broadcast operation occurs, the process 883 in FIG. 19 determines whether the read data is a numeric string or a character string, thereby determining whether to notify by telephone or e-mail. Just do it. Whether it is a numeric string or a character string can be determined according to the character code regulations such as ASCII code. Processing may be performed.

  FIG. 58 is a diagram illustrating an example of starting an e-mail notification process when notifying the alert information by e-mail. Since FIG. 58 is a continuation of FIG. 10 and cannot be described in FIG. When the call connection control unit 11 detects the mail address in the broadcast number storage area of the service subscriber database 100, the call connection control unit 11 displays the notification 15 shown in FIG. The mail address of the subscriber or the mail address of the broadcaster is added to the additional information and notified to the apparatus control unit 15.

  FIG. 59 and FIG. 60 are diagrams showing an example of creating the contents of an email when notifying the alert information by email. 59 is a series of FIG. 12 and is not shown in FIG. The data 770 is a data format when the device control unit 15 that has received the notification 15 from the call connection control unit 11 instructs the voice synthesis unit 14 to operate. In order to create an e-mail by itself, the device control unit 15 first issues an operation instruction 50 to transmit the voice guidance data held by the voice synthesizer 14 when notifying the service subscriber himself / her by e-mail. In response to this, the synthesizing unit 14 sends the guidance described in the operation instruction 5 in FIG. 13 to the apparatus control unit 15 as text data, like the operation instruction 50 in FIG. The device control unit 15 creates an e-mail using the mail address of the service subscriber already notified from the call connection control unit 11 as the destination and text data sent from the speech synthesizer 14 as the mail content. Send to the mail server 5201. When an e-mail notification is made to the broadcaster of the service subscriber, an operation instruction 51 is issued so as to transmit the voice guidance data possessed by the voice synthesizer 14, and the voice synthesizer 14 responds accordingly by operating the operation instruction shown in FIG. Like 51, the guidance described in the operation instruction 7 in FIG. 13 is sent to the apparatus control unit 15 as text data. The device control unit 15 uses the e-mail address to the broadcaster of the service subscriber already notified from the call connection control unit 11 as the destination, text data sent from the speech synthesizer 14 as e-mail content, and e-mail. It is created and sent to the mail server 5201. When there are a plurality of broadcasters, a plurality of e-mail addresses and data notified from the call connection control unit 11 can be set as destinations to perform simultaneous distribution as in a general electronic mail system.

  In this method, the service provision fee can be changed according to the number of registered broadcasters and connection permitters. An example of this is shown in FIG. 61. FIG. 61 is a separate description of the part that could not be described in FIG. 33, and the communication between the fraud prevention countermeasure devices and between the fraud prevention countermeasure device and the operation center 50. The example of the data format of communication is shown. As shown in FIG. 61, the command is “8” to clearly indicate that the communication is for exchanging the registration status of the database, and the parameter type is either “20: DB registration addition” or “21: DB registration deletion”. If the communication contents include the telephone number data of the broadcaster and the connection permitter in the data content, the registration status can be grasped on the operation center 50 side, and the details for the service subscriber are detailed. It becomes possible to set the price. This inter-device communication may be performed when a database change occurs, or may be performed at a certain time interval.

In this method, it is possible to cope with the case where the broadcaster or the connection permitter cancels the telephone contract and the telephone number does not exist from the telephone network. When canceling a relative telephone contract such as a broadcaster or a connection permitter, it is possible for a service subscriber to perform an operation of registering and deleting the corresponding telephone number by the method described so far in this specification. However, if the operation is not performed, registration of the phone number with which the contract has been canceled will remain, but the phone number with which the contract has been canceled will contract with a service subscriber at all. In such a case, there may be a problem that a broadcast notification is sent to a person who is not related at all, or when a call connection from that person occurs, the connection permission number is used, so that a call connection can be made without protection.
Therefore, in this method, when the broadcaster or connection permitter cancels the telephone contract, the corresponding telephone number is automatically deleted from the database. When the telephone contract is canceled, the information regarding the corresponding telephone number is deleted at the operation center 50. At that time, as shown in FIG. 61, the inter-device communication data 3000 communicates with each fraud countermeasure device to automatically operate the service subscriber database 100. Specifically, the inter-device communication data 3000 is communicated to all fraud countermeasure devices including the command “1: database change request”, the parameter type “22: search deletion”, and the phone number for which the contract is canceled in the data content. . For the parameter type “22: Delete search”, if there is the same phone number as the canceled phone number in the service subscriber database, the phone number is deleted and the subsequent data is pre-packed, and the contract is canceled in the service subscriber database. If there is no phone number that is the same as the phone number, no action will be taken.

In this method, a fraud countermeasure service subscriber can voluntarily perform countermeasure processing. In the case of fraud crimes using the telephone, there are cases in which the other party is trusted in a story that has nothing to do with fraud in the first few times, and finally money is paid. In such a case, in the system for detecting fraud, crime cannot be detected at the initial stage. However, the service subscriber may be suspicious because of a difference in personal characteristics, such as the fact that his / her own family is known, but the voice quality is too different, the wording and intonation are different, etc. The function to do is desired. The same applies when selling expensive products semi-forcibly. As a method for dealing with such a case, there is a method in which a service subscriber notifies a warning to the fraud countermeasure device by pressing, for example, a “#” button during a call.
Specifically, the “#” sound is detected by the voice recognition unit 13 and notified to the device control unit 15 as shown in FIG. 16, and the device control unit 15 notifies the call connection control unit 11 including the call identifier. If 10 is notified, the calling telephone number can be specified from FIG. When the calling phone number is a mobile phone number, that is, when the upper three digits of the phone number are 090 or 080, the location of the outgoing phone is specified by GPS (Global Positioning System) in conjunction with the mobile phone network. At this time, the inter-device communication data is also defined between the fraud countermeasure device and the mobile phone network device as shown in FIG. In FIG. 61, for example, a command is set as position information “9”, a parameter type is set as “23”, data communication is performed including the calling telephone number in the data content, and position information is obtained by the mobile phone network device, and the response is returned. The parameter type is “24”, and communication is performed by including the location information (latitude, longitude) of the calling telephone in the data content. The fraud countermeasure device provides support to stop the spread of crime by displaying position information along with an alarm on the device operation unit 20 or notifying a related organization such as the police by e-mail.

FIG. 62 is a diagram illustrating a configuration example of a telephone having a fraud countermeasure function using a telephone. The telephone 5800 includes a control unit 5801 for controlling a fraud countermeasure application, a telephone network interface unit 5802 that serves as an interface with the telephone network, and text-recording or recording a human voice in the middle of a call. When a word frequently used in crime is recognized, a voice recognition unit 5803 having a function of marking the term and a call that clearly indicates that the call is applicable to this service in a fraud prevention service, or a call that has already been disconnected A voice synthesizer 5804 that warns that there is a high possibility of fraud, and sends out a voice guidance that guides the registered content registration status to this service, and results and recorded data recognized by the voice recognition unit 5803, In addition, a call log database 5806 for storing the incoming / outgoing telephone number and date / time when the corresponding call was made, and voice authentication A voice data unit for recognition 5807 for storing voice data to be referred to when the unit 5803 performs voice recognition processing, and a voice data for synthesizing for storing voice data as original data for creating guidance related to the application in the voice synthesis unit 5804 Voice database unit 5808, telephone number database 5809 for storing the broadcaster number, connection permission number, suspected telephone number as shown in FIG. 2 and the confirmed fraud number shown in FIG. 4, telephone numbers and warnings, etc. A display unit 5810 for displaying, a push button 5811 for inputting a telephone number, a voice selector for separating and multiplexing voice data into input and output, a speaker 5813 for transmitting a voice signal to the telephone user, and a voice of the telephone user. A microphone 5814 for input.
When there is an incoming call, the telephone 5800 is notified of a signal from the telephone network interface 5802 to the control unit 5801 and starts operating the application. The fraud countermeasure application uses the same processing procedure as described for the fraud control device 1 shown in FIG. It is possible to call attention and to notify experts of fraud crimes. However, each database deployed inside the phone needs to be rewritten to prepare for a new fraud or to refuse connection from a fraudulent telephone number. Therefore, as shown in FIG. 62, a server 5831 having a fraud countermeasure database is provided in the telephone network 5830 to which the telephone 5800 is connected. This server 5831 has a data group as shown in FIG. 3, FIG. 13, FIG. 15, and FIG. 32, and accumulates new phone numbers and new terms collected from each telephone with a fraud countermeasure function as needed. The telephone 5800 downloads the latest information from the server 5831.
In the telephone 5800, the mail address registration of the broadcaster can be input with the push button 5811 so that characters can be input with a general mobile phone. Further, the alerting information can be displayed on the display unit 5811 by using text data in the voice guidance database 5808 instead of voice guidance.
