Description

The present invention enables a fixed telephone that enables a quick response so that the user of the fixed telephone is not a victim of the special fraud when a call from a special fraudster or the like that requires caution is received on the protected fixed telephone. The purpose is to provide a warning / incoming call notification device.

There are frequent special frauds in which people pretend to be family members or acquaintances to make phone calls and deceive money from the elderly who receive the calls. As an optional service for landlines, there is a number display (registered trademark) that displays the incoming phone number, and if you use this service, the user of the landline who received the incoming call will be the caller's phone number (the caller's phone number (registered trademark). It is possible to know the caller ID). However, since the special fraudsters are skillfully guided by pretending to be relatives, acquaintances, people of public institutions, etc., they believe that the call is from relatives, etc., or are upset by what they hear on the phone. It is difficult for a user to recognize that the call should be watched from the caller ID. For this reason, simply notifying the landline user of the caller ID is not an effective means of preventing fraudulent damage.

Therefore, a control server connected to the mobile communication network records the conversation between the registered telephone and the fraudulent telephone, and it is dangerous based on the number of specific words (such as words used in special fraud) contained in the conversation. A system for determining the degree has been proposed (see, for example, Patent Document 1). According to the system described in Patent Document 1, an email is sent to a mobile terminal owned by a family member or the like of a registered telephone user, or voice is used, depending on the degree of risk determined from the conversation between the registered telephone and the fraudulent telephone. Cut off the call. By automatically executing the process for preventing such fraud, it is possible to prevent the registered telephone user from becoming a victim of fraud.

Japanese Patent No. 6496448

However, the invention described in Patent Document 1 requires a technique of monitoring and recording a call to a registered telephone on a network, a technique of determining the possibility of special fraud from the conversation content, and the like, which makes the system complicated. Therefore, the usage fee for the service must be high.

Therefore, an object of the present invention is to provide a warning / incoming notification device for a fixed telephone, which has a simple configuration for a fixed telephone, can determine the possibility of special fraud, and can notify an appropriate party.

In order to solve the above-mentioned problems, the fixed-line telephone alert / incoming call notification device includes a caller ID acquisition means for acquiring a caller ID of a call made to a fixed-line telephone to be protected via a fixed telephone line, and the caller ID. An incoming call determination function unit that determines whether the caller ID acquired by the acquisition means is a safe call that satisfies a predetermined safety condition or a warning call that does not meet the safety condition, and the incoming call determination function unit performs the warning call. It is characterized in that it is provided with a warning / incoming call notification function unit that can notify a predetermined notification destination when it is determined.

Further, in the above configuration, the incoming call determination function unit has a safe telephone number storage means for storing one or more safe telephone numbers, which is a secure telephone number, and the caller number acquired by the caller number acquisition means. And the safe phone number stored in the safe phone number storage means, and if there is a safe phone number that matches the caller ID, it is determined that the call is safe and the caller ID matches the caller ID. It may be provided with a telephone number comparison means for determining the alert incoming call when there is no secure telephone number.

Further, in the above configuration, the alert incoming call notification function unit determines that the alert call is received by the notification destination telephone number storage means that stores one or more predetermined notification destination telephone numbers as the notification destination and the incoming call determination function unit. If this is the case, the fixed telephone line calling means for making a call to the notified telephone number stored in the notified telephone number storage means using the fixed telephone line to which the fixed telephone to be protected is connected, and It may be provided with.

Further, in the above configuration, the alert incoming call notification function unit determines that the alert call is received by the notification destination telephone number storage means that stores one or more predetermined notification destination telephone numbers as the notification destination and the incoming call determination function unit. If so, a call is made to the notification destination telephone number stored in the notification destination telephone number storage means using a notification call line different from the fixed telephone line to which the protection target fixed telephone is connected. It may be provided with a communication line transmission means for notification.

Further, in the above configuration, the notification call line uses the wireless call line of the mobile communication service, and the notification call line transmission means may transmit to the notification destination telephone number by the wireless call line. good.

Further, in the above configuration, the alert incoming call notification function unit is determined to be the alert incoming call by the notification destination address storage means that stores one or more predetermined notification destination addresses as the notification destination and the incoming call determination function unit. In this case, the data communication line may be provided with a data communication means for transmitting the alert incoming call occurrence information to the notification destination address stored in the notification destination address storage means.

According to the alert incoming call notification device for fixed telephones having the above configuration, when an incoming call arrives at the fixed telephone to be protected, the incoming call determination function unit receives a safe incoming call or an alert incoming call based on the caller ID acquired by the caller ID acquisition means. If it is a warning call, the warning call notification function unit notifies a predetermined notification destination. That is, with a simple configuration for a fixed telephone, it is possible to determine a warning call that may be a special fraud and notify the appropriate party of the occurrence of the warning call. Then, if a person who receives a notification of a warning call from a fixed-line telephone warning call notification device as a notification destination takes measures such as contacting the user of the fixed-line telephone to be protected, the damage caused by special fraud can be prevented. ..

It is a schematic block diagram of the alert incoming call notification device for a fixed telephone which concerns on 2nd Embodiment. It is a schematic block diagram of the alert incoming call notification device for a fixed telephone which concerns on 3rd Embodiment.

Next, an embodiment of the alert / incoming call notification device for a fixed telephone will be described in detail with reference to the attached drawings.

The alert / incoming call notification device 10A for a fixed telephone according to the first embodiment shown in FIG. 1 is used by being attached to a fixed telephone line TL connected to the fixed telephone 20 to be protected. For example, the modular jack of the telephone cable connected to the fixed telephone 20 is removed, connected to the modular connector of the alert incoming call notification device 10A for the fixed telephone, and the modular telephone cable extending from the alert incoming call notification device 10A for the fixed telephone. Connect the jack to the modular connector of the fixed telephone 20. That is, it is possible to easily introduce the warning / incoming call notification device 10A for a fixed telephone with the existing equipment without any special modification to the fixed telephone 20 to be protected or the fixed telephone line TL. The warning / incoming call notification device 10A for a fixed telephone may be operated only by the power supplied from the telephone line, or may be operated by taking out the power from a storage battery such as a household power outlet or a dry battery. Further, the fixed telephone line TL to which the fixed telephone 20 is connected may be an analog line or a digital line, but it is necessary to receive a caller ID notification service.

The fixed-line telephone alert / incoming call notification device 10A acquires the caller ID of the telephone number of the fixed telephone 20 to be protected by the caller ID acquisition means 11. The caller ID acquired by the caller ID acquisition means 11 is supplied to the incoming call determination function unit 12, and whether the caller ID is a safe call that satisfies a predetermined safety condition or a warning call that does not meet the safety condition is received. The determination function unit 12 determines. When the incoming call determination function unit 12 determines that the incoming call is alert, the alert incoming call determination result is supplied to the alert incoming call notification function unit 13A, and the alert incoming call notification function unit 13A notifies the predetermined notification destination that the alert incoming call has been received. .. That is, it is possible to prevent the damage caused by special fraud by taking measures such as promptly contacting the user of the fixed telephone 20 by the person who receives the notification of the alert incoming call from the alert incoming call notification device 10A for the fixed telephone. can.

The incoming call determination function unit 12 includes, for example, a telephone number comparison means 121 and a secure telephone number storage means 122. The safe telephone number storage means 122 stores one or more safe telephone numbers, which are safe telephone numbers of relatives, acquaintances, public institutions, and the like. When the telephone number comparison means 121 receives the caller ID acquired by the caller ID acquisition means 11, the telephone number comparison means 121 reads the safety telephone number from the safety telephone number storage means 122 and compares it with the caller ID. If there is a number that matches the caller ID among the safe phone numbers stored in the secure phone number storage means 122, it is determined that the incoming call is a safe call because it is a safe call from a relative, acquaintance, public institution, etc. do. When the telephone number comparison means 121 determines that the incoming call is safe, the alert incoming call notification device 10A for a fixed telephone does nothing in particular.

On the other hand, if there is no number that matches the caller ID among the secure phone numbers stored in the secure phone number storage means 122, this incoming call is not a safe call from a relative, acquaintance, public institution, etc., but a special fraud. Since there is a possibility of an incoming call that should be watched, such as a criminal or telephone sales, it is judged as a warning call. Then, when the telephone number comparison means 121 determines the alert incoming call, the result is transmitted to the alert incoming call notification function unit 13A.

It should be noted that the condition for the incoming call determination function unit 12 to determine an alert call does not necessarily have to be "all cases where the safe telephone number and the caller ID do not match". For example, a dangerous telephone number storage means is provided separately from the safe telephone number storage means 122, and a telephone number that has been misused in special fraud or telephone sales is stored as a dangerous telephone number. The telephone number comparison means 121 first compares the caller ID with the safe telephone number, and if there is no matching telephone number, subsequently compares the caller number with the dangerous telephone number. Then, if there is no dangerous telephone number that matches the caller ID, the telephone number comparison means 121 determines that the first alert call has a low alert level. However, if there is a dangerous telephone number with the same caller ID, the telephone number comparison means 121 determines that the call is a second alert call with a high alert level. Further, when there is an incoming call not notified by the caller, the caller ID acquisition means 11 cannot acquire the caller ID, but can detect that the incoming call has not been notified. Therefore, when there is an incoming call not notified by the caller, the telephone number comparison means 121 may determine that there is a third alert incoming call having a higher alert level.

The alert incoming call notification function unit 13A includes, for example, a fixed telephone line transmission means 131 and a notification destination telephone number storage means 132. The notification destination telephone number storage means 132 stores one or more contact telephone numbers (predetermined notification destination telephone numbers as notification destinations) of a person who calls attention to a warning call such as a relative. The fixed-line telephone line calling means 131 is protected when it is determined by the telephone number comparing means 121 of the incoming call determination function unit 12 that the incoming call is a warning call (when it is determined that the incoming call may be a special fraud). The fixed telephone line TL to which the fixed telephone 20 of the above is connected is used to make a call to the notified telephone number stored in the notified telephone number storage means 132. A person who receives a warning call as a notification destination knows that the user of the fixed telephone 20 has received a call that may be a special fraud, so he / she directly contacts the user of the fixed telephone 20 to detect the special fraud. By alerting you to the possibility that it was a phone call, it is more likely that you will be able to prevent fraud.

When two or more notification destination telephone numbers are stored in the notification destination telephone number storage means 132, for example, when a predetermined high priority notification destination telephone number is called and the call is not received, the following You may call the telephone number of the priority notification destination. In this way, even if a person who has a telephone with a high-priority notification telephone number cannot answer the call for some reason and cannot receive a notification that there is a warning call, the telephone with another notification telephone number can be used. It is more likely that the owner will be notified that there is a warning call and can take appropriate measures. Further, when calling the notification destination telephone number from the fixed telephone line calling means 131, it is sufficient to notify the presence of a warning call by playing a relatively simple warning sound or recorded voice, or various information (warning incoming call) by voice synthesis means. You may want to read out the time you received the call, the caller ID, etc.).

As described above, according to the fixed-line telephone alert / incoming notification device 10A according to the first embodiment, when there is an incoming call to the fixed telephone 20 to be protected, the caller number acquired by the caller ID acquisition means 11 is used as the basis for the caller ID. The incoming call determination function unit 12 determines whether the incoming call is a safe call or a warning call, and if it is a warning call, the warning incoming notification function unit 13A notifies a predetermined notification destination. That is, with a simple configuration attached to each fixed telephone 20, the possibility of special fraud can be determined and the appropriate party can be notified. Then, if a person who receives the notification from the fixed telephone warning / incoming notification device 10A as the notification destination takes measures such as contacting the user of the fixed telephone 20 to be protected, the damage caused by special fraud can be prevented.

Further, in the fixed-line telephone alert incoming call notification device 10A, the alert destination telephone number is called via the fixed telephone line TL to which the fixed telephone 20 to be protected is connected, and the alert incoming call is notified. A person who uses the telephone with the notified telephone number can recognize that the telephone is from the landline telephone 20 to be protected. That is, since the call to the notification destination made by the alert incoming call notification function unit 13A provided with the fixed telephone line transmitting means 131 is directly linked to the telephone number of the fixed telephone 20 to be protected, the fixed telephone 20 to be protected is used. There is no need to separately provide information for identification.

Since the safe telephone number and the notification destination telephone number must be set in order to use the fixed telephone alert call notification device 10A, the safety telephone number storage means 122 and the notification destination telephone number storage means 132 are used. It is desirable that the operation of storing the telephone number is easy. For example, an input means such as a numeric keypad may be provided on the main body of the alert / incoming call notification device 10A for a fixed telephone so that the user can input the information on the spot. Alternatively, a secure telephone number can be obtained by setting a portable small recording medium (SD memory card, USB memory, etc.) in which a telephone number is input according to a predetermined format from a PC, smartphone, or the like in the alert call notification device 10A for a fixed telephone. It may be configured to function as the storage means 122 and the notification destination telephone number storage means 132.

Since the fixed-line telephone alert / incoming call notification device 10A of the first embodiment is configured to notify the notification destination using the fixed-line telephone line TL to which the fixed-line telephone 20 to be protected is connected, the fixed-line telephone 20 to be protected is configured. There is a drawback that it is not possible to notify the notification destination of the occurrence of a warning call while talking. For example, if a fixed-line telephone 20 to be protected receives a call from a special fraudster, even if it is determined that the call is a warning call from this caller ID, the notification destination is warned until the call ends and the line becomes available. It is not possible to notify the occurrence of an incoming call. Even if the alert incoming call notification function unit 13A calls the alert destination and notifies the occurrence of the alert incoming call immediately after the call with the special fraudster ends, the person using the telephone with the alert destination telephone number is the landline phone to be protected. There may be a time lag of tens of seconds to minutes before making a call to alert 20. In the meantime, if a person using the landline telephone 20 to be protected goes out to go to a bank or the like, it is meaningless to call the landline telephone 20.

Therefore, the fixed-line telephone alert / incoming call notification device 10B of the second embodiment shown in FIG. 2 can notify the alert destination of the occurrence of the alert / incoming call even when the fixed telephone 20 to be protected is in a call. The same configuration as that of the fixed telephone alert / incoming call notification device 10A of FIG. 1 described above in the fixed telephone alert / incoming call notification device 10B of FIG. 2 is designated by the same reference numeral and the description thereof will be omitted.

The warning / incoming notification function unit 13B of the fixed-line telephone warning / incoming notification device 10B includes, for example, a notification destination telephone number storage means 132 and a notification communication line transmission means 133. The notification destination telephone number storage means 132 stores one or more notification destination telephone numbers predetermined as notification destinations. When the incoming call determination function unit 12 determines that the incoming call line is a warning call, the notification call line transmission means 133 uses a notification call line different from the fixed telephone line TL to which the fixed telephone 20 to be protected is connected. Make a call to the notification destination telephone number stored in the destination telephone number storage means 132. When two or more notification destination telephone numbers are stored in the notification destination telephone number storage means 132, the notification call line transmission means 133 calls a predetermined notification destination telephone number having a high priority. If you do not receive a call, you may try to call the next priority notification phone number.

As the communication line for notification, for example, a wireless communication line of a mobile communication service can be used. In this case, the notification communication line transmission means 133 has a function of being able to connect to the radio base station of the carrier which is the mobile communication service provider, and notifies by transmitting to the notification destination telephone number by the wireless communication line. It is possible to notify the occurrence of a warning call first.

The notification communication line is not limited to the wireless telephone line, and a fixed telephone line different from the fixed telephone line TL connected to the fixed telephone 20 to be protected can be pulled in and used. Further, since the IP telephone service using an optical line can use a plurality of telephone numbers in one contract, a telephone number different from the telephone number assigned to the fixed telephone 20 is assigned to the fixed telephone alert / incoming call notification device 10B for notification communication. You may use it as a line. Alternatively, a digital ISDN line may be introduced, one B channel may be connected to the fixed telephone 20 to be protected, and the other B channel may be connected to the notification telephone line transmitting means 133 of the fixed telephone alert / incoming notification device 10B. good.

As described above, according to the fixed-line telephone alert / incoming notification device 10B according to the second embodiment, when there is an incoming call to the fixed telephone 20 to be protected, the caller number acquired by the caller ID acquisition means 11 is used as the basis for the incoming call. The incoming call determination function unit 12 determines whether the incoming call is a safe call or a warning call, and if it is a warning call, the warning incoming notification function unit 13B notifies a predetermined notification destination. That is, with a simple configuration attached to each fixed telephone 20, the possibility of special fraud can be determined and the appropriate party can be notified. Then, if a person who receives the notification from the fixed telephone warning / incoming notification device 10B as the notification destination takes measures such as contacting the user of the fixed telephone 20 to be protected, the damage caused by special fraud can be prevented.

Further, in the fixed-line telephone alert incoming call notification device 10B, the alert incoming call occurrence is notified by calling the notification destination telephone number using a notification call line different from the fixed-line telephone line TL to which the fixed telephone 20 to be protected is connected. Therefore, even when the fixed telephone line TL is in use, it is possible to quickly call the notification destination. Therefore, a person who uses a telephone with a notification destination telephone number that has received a call from the fixed-line telephone alert / incoming call notification device 10B can switch to the protected fixed-line telephone 20 without a break after the call of the protected fixed-line telephone 20 ends. Since it is possible to make a call, it is more likely that a person using the protected fixed telephone 20 can be alerted before going out.

Since the alert incoming call notification device 10A for the fixed telephone of the first embodiment and the alert incoming call notification device 10B for the fixed telephone of the second embodiment notify the occurrence of the alert incoming call by calling the notification destination telephone number, the telephone cannot be connected. There is a drawback that the user of the fixed telephone 20 to be protected cannot be warned. Further, if a plurality of notification destination telephone numbers are stored in the notification destination telephone number storage means 132, the possibility that the call made from the fixed-line telephone alert incoming call notification devices 10A and 10B will be connected to the notification destination telephone number can be increased. , The more notification destinations you call, the more wasted time will pass. When a call made from the alert incoming call notification devices 10A and 10B for fixed telephones is finally connected to the notification destination telephone number, and a person using the telephone with the connected notification destination telephone number makes a call to the fixed telephone 20 to be protected. If a person using the fixed telephone 20 to be protected has already gone out to go to a bank or the like, it is meaningless to call the fixed telephone 20.

If the telephone number of a portable wireless communication terminal such as a smartphone is used as the notification destination telephone number, there is a high possibility that the incoming call from the alert incoming call notification devices 10A and 10B for fixed telephones will be noticed, but during work or in public transportation. It is not uncommon for people to be unable to answer incoming calls, such as during use. On the other hand, although it is difficult to make a call, it is considered that there are relatively many situations where it is possible to read an incoming message.

Therefore, the warning / incoming call notification device 10C for a fixed telephone according to the third embodiment shown in FIG. 3 does not make a call to the notification destination, but transmits the warning / incoming call occurrence information to the notification destination by data communication. In the fixed telephone alert / incoming notification device 10C of FIG. 3, the same components as those of the fixed telephone alert / incoming notification devices 10A and 10B of FIGS. 1 and 2 described above are designated by the same reference numerals and the description thereof will be omitted. ..

The warning / incoming notification function unit 13C of the fixed-line telephone warning / incoming notification device 10C includes, for example, a notification destination address storage means 134 and a data communication means 135. The notification destination address storage means 134 stores one or more notification destination addresses predetermined as notification destinations. When the incoming call determination function unit 12 determines that the incoming call is alert, the data communication means 135 transmits the alert incoming call occurrence information to the broadcast destination address stored in the broadcast destination address storage means 134 using the data communication line. Of course, since the fixed telephone 20 to be protected can transmit the alert incoming call occurrence information by the data communication means 135 even during a call, the alert incoming call occurrence information can be notified to the notification destination as soon as possible.

As the data communication line used by the data communication means 135, a public communication network such as the Internet (registered trademark) can be used, and for example, the line may be connected via a wireless LAN in the house. Alternatively, an Internet connection service provided by a cable TV company or a communication carrier may be used. The notification destination address is destination information whose destination is uniquely determined in the communication network to which the data communication means 135 is connected by using the data communication line, and is managed by an ISP, a communication carrier, or the like on the Internet. You can use your personal email address. When using the short message service provided by the wireless communication carrier, the telephone number of the mobile phone as the notification destination can be used as the notification destination address.

When two or more notification destination addresses are stored in the notification destination address storage means 134, the data communication means 135 may transmit the alert incoming call occurrence information to all the notification destination addresses at the same time. Further, when the level is set for the alert incoming call, the address group to be transmitted may be changed according to the alert incoming call level. For example, when the alert level is low, a normal notification address group composed of a relatively small number of notification destination addresses is used, and when the alert level is high, an emergency notification destination including all registered notification destination addresses is used. Use a group of addresses. When the alert level is low, it is sufficient to respond to the alert incoming call with a small number of people, but when the alert level is high, it is desirable that a large number of people respond quickly to the alert incoming call.

As described above, according to the fixed-line telephone alert / incoming notification device 10C according to the third embodiment, when there is an incoming call to the fixed telephone 20 to be protected, the caller number acquired by the caller ID acquisition means 11 is used as the basis for the incoming call. The incoming call determination function unit 12 determines whether the incoming call is a safe call or a warning call, and if it is a warning call, the warning incoming notification function unit 13C notifies a predetermined notification destination. That is, with a simple configuration attached to each fixed telephone 20, the possibility of special fraud can be determined and the appropriate party can be notified. Then, if a person who receives the notification from the fixed telephone warning / incoming notification device 10C as the notification destination takes measures such as contacting the user of the fixed telephone 20 to be protected, the damage caused by special fraud can be prevented.

Further, in the warning / incoming call notification device 10C for a fixed telephone, the warning / incoming call occurrence information is transmitted to the notification destination address using the data communication line, so that the person using the notification destination address is more alert than when receiving a call. There is an advantage that it is easy to check the incoming call occurrence information. As a result, a person using the notification destination address is likely to be aware of the warning / incoming call occurrence information from the fixed-line telephone warning / incoming notification device 10C as soon as possible, and can quickly deal with the user of the fixed-line telephone 20 to be protected. It is effective in preventing damage from special fraud. Moreover, since a relatively large amount of information can be sent to the notification destination in one communication in data communication, even when sending information that takes time for notification by call (such as alert call occurrence time and caller ID), transmission is possible. There is an advantage that the user of the destination address can recognize it instantly.

Although the embodiment of the alert / incoming call notification device for a fixed telephone according to the present invention has been described above based on the attached drawings, the present invention is not limited to these embodiments, and the configuration described in the claims. It may be carried out by diverting known and existing equivalent technical means as long as the above is not changed.
