  As described in Patent Document 1, if it is configured to start a call if the passwords match, it is possible to prevent incoming calls from other parties for mischief and fraud purposes. Scams that abuse the number display function have emerged. For example, when a fraudulent user makes a call to the other party from a public phone or home, the other party's acquaintance's phone number is sent to the other party, and the other party who received the call has received a call from an acquaintance As a result, there is a problem in that money is transferred to a fraudulent user due to scamming by a fraudulent user. In this way, it has become a social problem, such as being used for “transfer fraud”.

  In view of the above circumstances, an object of the present invention is to provide a telephone device that can prevent a user on the receiving side from being damaged by fraud or the like due to a spoofing act of a caller.

The invention of claim 1 is connected to a telephone line, a telephone device that have a number display function of receiving information about the caller's telephone number sent from the telephone line when a call arrives, a further predetermined security code Storage means for storing and display means for outputting voice information asking the caller for a code number when receiving an incoming call, and the code number entered by the caller matches the code number stored in the storage means In such a case, control is performed so that a call can be made with the caller. On the other hand, if the password entered by the caller does not match the password stored in the storage means, or the password is sent from the caller. If a certain time has passed without receiving the password, the password entered by the caller does not match the password stored in the storage means or the password from the caller. And having a control unit for controlling to display on the display means the information indicating that the predetermined time has elapsed without receiving a.

According to the first aspect of the present invention, when voice information asking the caller for a code number is output when an incoming call is received , and the code number input by the caller matches the code number stored in the storage means, the control means Is controlled so as to be able to talk to the caller. As a result, it is possible to prevent the user from receiving a call from an undesired destination and matching with fraud or the like as long as the passwords do not match. Further, in order to display on the display means the information that the password entered by the caller does not match the password stored in the storage means or the information that a certain time has passed without receiving the password from the caller, It is possible to notify the user that the incoming call is from an undesired destination.

The invention of claim 2 is connected to a telephone line, a telephone device having a number display function of receiving information about the caller's telephone number sent from the telephone line when receiving a call, a display unit, predetermined telephone Storage means for storing a number and a predetermined personal identification number in association with each other, and inquiring the personal identification number to the caller when the caller telephone number received at the time of an incoming call matches the telephone number stored in the storage means Voice information is output, and when the personal identification number input by the caller matches the personal identification number stored in the storage means, control is performed so that a call can be made with the caller. When the password entered by the sender does not match the password stored in the storage means or when the password has not been received from the sender and a certain time has elapsed, the sender enters the password. Control to display on the display means information indicating that the personal identification number does not match the personal identification number stored in the storage means or information indicating that the personal identification number has not been received from the sender. And a control means.

According to the second aspect of the present invention, when the caller telephone number received at the time of incoming call matches the telephone number stored in the storage means, the control means outputs voice information asking the caller for the password, When the personal identification number input by the caller matches the personal identification number stored in the storage means, the control means controls the telephone caller to be in a communicable state. As a result, even if the caller's phone number matches, it will not be possible to talk to the caller unless the PIN number also matches, and the caller's impersonation will prevent the receiving user from being damaged by fraud it can. Further, in order to display on the display means the information that the password entered by the caller does not match the password stored in the storage means or the information that a certain time has passed without receiving the password from the caller, It is possible to notify the user that the incoming call is from an undesired destination.

According to the present invention, it is possible to prevent a user from receiving an incoming call from an undesired destination and receiving damage such as fraud. In addition, since the information that the password entered by the caller does not match the password stored in the storage means or the information that the password has not been received from the caller and a certain period of time has passed is displayed, It is possible to notify the user that the incoming call is from a desired destination.

  Next, a telephone device according to an embodiment of the present invention will be described with reference to the drawings. The telephone device of the present embodiment will be described with respect to a wired telephone device that performs wired communication. However, the present invention is not limited to this type of telephone device, and a wireless telephone device that performs wireless communication (for example, a cordless telephone device). It can also be applied to a telephone device.

  As shown in FIG. 1, the telephone device 10 includes a line control unit 14 to which a telephone line 56 is connected. The line control unit 14 performs open control or close control of the telephone line 56, incoming call detection, and the like. The line control unit 14 has a built-in ND unit 58 for realizing a number display function for receiving information related to a caller telephone number transmitted from the telephone line 56 when an incoming call is received.

  In addition, a switching circuit 22 is connected to the line control unit 14. A first speaker 26 is connected to the switching circuit 22 via an amplifier circuit 24. The first speaker 26 converts the electric signal of the line control unit 14 amplified by the amplifier circuit 24 into sound.

And switching to the amplifying circuit 28 side for the microphone 30.

  A control circuit (control means) 36 is connected to the line control unit 14 and the switching circuit 22. Switching by the switching circuit 22 described above is performed under the control of the control circuit 36. The control circuit 36 is connected to the ROM 38 and controls each unit based on a system program stored in the ROM 38. The control circuit 36 has a built-in counter 60 that counts a predetermined time.

  The control circuit 36 is connected to a RAM 40 in which predetermined information necessary for the operation of the control circuit 36 is stored. Further, the control circuit 36 can transmit an e-mail to an external communication device (for example, a telephone device) via the line control unit 14.

  Here, predetermined information is stored in the RAM 40. Specifically, a predetermined telephone number (for example, a telephone number of family, friend, acquaintance, etc.) and a predetermined personal identification number (for example, a 4-digit number) are stored in association with each other. In addition, you may also use the password used in the case of remote control of the outside line installed in an answering machine etc. as a password.

  Further, the RAM 40 stores voice data for voice output to the caller. In the present embodiment, for example, voice data such as “Please enter your password” or “Your password is wrong”, or when the password entered by the caller matches the password stored in the RAM 40, are received. Voice data relating to a pseudo ringback tone for notifying a caller of a ringing tone ringing state where a sound is ringing is stored. Further, the RAM 40 stores data related to NG information indicating the content that the password entered by the caller does not match the password stored in the RAM 40, and NG indicating the content that has passed a certain time without receiving the password from the caller. Data related to information is stored.

  Instead of the RAM 40, a nonvolatile memory such as a flash memory may be used.

  An input unit 44 is connected to the control circuit 36. The input unit 44 includes a numeric keypad 48 for inputting a telephone number and the like, a call key 50 for operating a call start, a cut key 52 for operating a call end, a function key 54 for setting various functions, And a power key 64 that stops lighting from the lighting unit 46, which will be described later, so that the telephone device 10 cannot ring (power-off state).

  The control circuit 36 is connected to an illumination unit 46 having a predetermined color LED element. The display 42 is given a predetermined color by the light emitted from the LED elements of the illumination unit 46.

  Next, the operation of the telephone device 10 according to the present embodiment will be described. FIG. 2 is a flowchart showing the operation of the telephone device 10 according to the present embodiment.

  As shown in FIG. 2, when there is an incoming call from the caller (step 10), the line control unit 14 is controlled by the control circuit 36, and even if the user at the receiving side picks up the handset, the call state with the caller An off-hook disable function is activated (step 12). At this time, the ND unit 58 receives information related to the caller telephone number (hereinafter, “caller telephone number” will be described as an example) from the telephone line 56 side. When the off-hook invalid function is activated, the control circuit 36 determines whether or not the caller telephone number received from the telephone line 56 side at the time of the incoming call matches a predetermined telephone number stored in the RAM 40 in advance ( Step 14). When the control circuit 36 determines that the caller telephone number received from the telephone line 56 at the time of incoming call matches the predetermined telephone number stored in the RAM 40 in advance, the line control unit 14 closes the telephone line 56. Controlled and line connection is realized (step 16). At this time, the first speaker 26 is controlled by the control circuit 36, and no ring tone is output from the first speaker 26 (no ringing tone). When line connection is realized, voice data stored in the RAM 40 in advance (for example, “Please enter your PIN”) to prompt the caller to send your PIN with a DTMF signal. ) Is controlled by the control unit 36 so as to send the synthesized voice to the telephone line 56 side. As a result, a predetermined voice message is output to the caller (step 18). At this time, the control circuit 36 controls the DTMF signal from the telephone line 56 to be in a monitoring state for a certain period (about 10 seconds at the longest). Next, it is judged by the control circuit 36 whether or not a personal identification number has been inputted by a dial operation of a telephone device (not shown) on the caller side (step 20). When the control circuit 36 determines that the personal identification number has been input, the control circuit 36 determines whether the personal identification number input by the caller matches the personal identification number previously stored in the RAM 40 (step 22). ). When the control circuit 36 determines that the password entered by the caller matches the password stored in advance in the RAM 40, the first speaker 26 is controlled by the control circuit 36, and a ring tone is output from the first speaker 26. Is output (step 24, ringing sound is generated). At this time, the control circuit 36 controls to send a pseudo ringback tone for notifying the ringing tone ringing state to the telephone line 56 side (step 26). Then, the line control unit 14 is controlled by the control circuit 36, and an off-hook effective function is activated to enable a call state with the caller when the user on the receiving side picks up the handset (step 28). Next, it is judged by the control circuit 36 whether or not the user on the receiving side responds to the incoming call (including an automatic answering by the answering machine function) (step 30). When it is determined by the control circuit 36 that the user on the called side has answered (including an automatic answering by the answering machine function), the control circuit 36 generates a call circuit for the telephone line 56 side, whereby the caller and the incoming call are received. It becomes possible to talk with the user on the side (step 32). When the call is terminated between the caller and the called user, the telephone line 56 is controlled to be opened by the line controller 14 and the communication state via the telephone line 56 is disconnected (step 34). As a result, the user on the receiving side can talk with the caller with peace of mind. If the control circuit 36 determines that the user on the called side is not responding (including an automatic answering by the answering machine function), the control circuit 36 disconnects the communication state via the telephone line 56. (Step 56), and if it is determined that the communication state via the telephone line 56 has been disconnected, the process ends. On the other hand, if it is determined that the communication state via the telephone line 56 has not been disconnected, the process returns to immediately before step 24.

  On the other hand, when the control circuit 36 determines that the password entered by the caller in step 22 does not match the password stored in the RAM 40 in advance, the voice data (for example, “password” stored in the RAM 40 in advance). The number is different ”, etc.), and the control unit 36 controls the synthesized voice to be transmitted to the telephone line 56 side. As a result, a predetermined voice message is output to the caller (step 36). Next, a code number is input a plurality of times by the caller, and the input code number does not match the code number stored in the RAM 40, and whether or not the input number of the code number from the caller is more than a predetermined number of times. Whether or not is judged by the control circuit 36 (step 38). When the control circuit 36 determines that the input error is greater than or equal to the predetermined number of times, the display 42 displays NG information indicating that the password entered by the caller does not match the password stored in the RAM 40. It is displayed together with the telephone number (step 40). Then, the line control unit 14 controls the opening of the telephone line 56, and the communication state via the telephone line 56 is disconnected (step 34). If the control circuit 36 determines that the number of input mistakes of the personal identification number from the caller is less than the predetermined number of times, the process returns to the step immediately before step 18.

  If no code number is input from the caller in step 20, it is determined by the counter 60 of the control circuit 36 whether or not a predetermined time has passed (step 42). When the counter 60 of the control circuit 36 determines whether or not the predetermined time has passed, NG information indicating the content of the fixed time that has not been received from the caller is displayed on the display 42 together with the caller telephone number. It is displayed (step 44). Then, it is determined by the control circuit 36 whether or not the communication state via the telephone line 56 has been disconnected (step 46). If it is determined that the communication state via the telephone line 56 has been disconnected, the process is terminated. To do. If the control circuit 36 determines that the communication state has not been disconnected, the process returns to immediately before step 20.

  Further, when it is determined by the control circuit 36 that the caller telephone number received from the telephone line 56 side at the time of an incoming call does not match the predetermined telephone number stored in advance in the RAM 40 at step 14, the first control circuit 36 The speaker 26 is controlled, and a ring tone is output from the first speaker 26 (step 48, ringing tone is generated). Then, it is determined by the control circuit 36 whether or not a call has been started between the caller and the called user (step 50), and it is determined that a call has been started between the caller and the called user. Then, the control circuit 36 generates a call circuit for the telephone line 56 side, and thereby a call-ready state is established in which the caller and the called-side user can talk (step 52). If the control circuit 36 determines that a call has not started between the caller and the called user, the process proceeds immediately before step 54 described later. It is determined by the control circuit 36 whether or not the communication state via the telephone line 56 has been disconnected (step 54). If it is determined that the communication state via the telephone line 56 has been disconnected, the process is terminated. If the control circuit 36 determines that the communication state has not been disconnected, the process returns immediately before step 52.

  As described above, according to the telephone device 10 of the present embodiment, when the caller telephone number received at the time of incoming call matches the telephone number stored in the RAM 40, the control circuit 36 asks the caller for the password. When the information is output and the password entered by the caller matches the password stored in the RAM 40, the control circuit 36 controls the caller to be in a call-ready state via the line control unit 14. Even if the caller telephone number matches, the caller cannot be in a callable state unless the passwords also match, and it is possible to prevent the receiving user from being damaged by fraud or the like due to the caller's impersonation action.

  When the caller telephone number received at the time of the incoming call matches the telephone number stored in the RAM 40, the control circuit 36 outputs the voice information without ringing the ringing tone, and the password entered by the caller is If it matches the password stored in the RAM 40, the control circuit 36 controls the ringing tone so that a call can be made with the caller. Until the password entered by the user matches the password stored in the RAM 40, the ring tone does not sound, so that the user on the called side does not answer by mistake, and the incoming call Noise caused by sound can also be prevented.

  Further, the control circuit 36 is controlled to be in a non-calling state in which a call cannot be made to the caller via the line control unit 14 until the password entered by the caller from the time of the incoming call matches the password stored in the RAM 40. Even when the user on the receiving side picks up the handset, the user on the receiving side does not talk with the caller.

  Further, when the password entered by the caller matches the password stored in the RAM 40, the control circuit 36 generates a pseudo ringback tone for notifying the ringing tone ringing state. Therefore, it is possible to prevent the caller from being irritated or uncomfortable.

  If the password entered by the caller does not match the password stored in the RAM 40, or if the password is not received from the caller and a certain time has elapsed, the line control unit 14 opens the telephone line 56. Since the communication state via the telephone line 56 is controlled, the incoming user can be prevented from being damaged by fraud and the like due to the spoofing act of the caller.

  Further, when the password entered by the caller does not match the password stored in the RAM 40, or when a certain time has elapsed without receiving the password from the caller, NG information is displayed on the display 42 together with the caller telephone number. Therefore, the user on the receiving side can know the caller telephone number and the NG information in association with each other, which can be used for crime prevention measures.
