There is also an intercom with a television camera, which allows a visitor to check the image of a visitor by adding a television camera. However, the intercom is originally intended for confirming visitors, and is not intended for security (security) directly. On the other hand, in order to prevent crime for general houses (households), a plurality of locks such as a double lock of an entrance door is a main means. However, at present, even if a plurality of locks are engaged, there is not much damage such that they are unlocked and entered into the nest.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a home security system capable of preventing the above-mentioned unauthorized intrusion and living with peace of mind.

[0004]

Means for Solving the Problems and Effects of the Invention In order to solve the above problems, a home security system of the present invention (Claim 1) is provided with a door or an entrance of a general house (hereinafter referred to as an entrance).
At the entrance), a personal identification machine is installed to identify individuals based on fingerprints, retinas, voiceprints, and other biometric features, or identification information such as cards, numeric keys, and other personal information. The identification information such as the biological characteristics or personal information of an authorized person (hereinafter collectively referred to as a family) is registered in the personal identification machine, and when entering the house from the entrance, the personal identification machine is used. A personal identification is performed to determine whether or not the person is a registrant of the family, and as a result, when the person is determined to be a registrant of the family, a signal to unlock the entrance door is output from the personal identification device. Unlocking signal output means is provided.

In the home security system having such a configuration, personal identification is performed by a personal identification device.
When it is determined that the registrant is a registrant based on the collation result, the registrant is allowed to enter the room only after an unlock signal is output from the unlock signal output means of the personal identification device to, for example, a lock at the entrance. Entry (intrusion) into a house other than the above can be prevented.

In order to solve the above problem, a home security system according to the present invention (claim 2) includes a personal identification device similar to that of claim 1, and uses the personal identification device to determine whether or not a registrant of a family is registered. A personal identification is performed to determine whether or not the family member in the house is based on the identification of the registrant identified by the personal identification device. It is characterized by providing a returnee notifying means for outputting information for notifying that the user has returned home.

As described above, personal identification is performed by the personal identification device, and when it is determined that the user is a registrant based on the verification result, personal information (name, etc.) identified by the verification is obtained.
By providing returnee notification means that outputs information to notify the family in the house who has returned home, the family in the house can identify who returned to the home before the identified person entered the room. Can be known. In particular, if personal identification is performed based on biometric characteristics, it is possible to prevent intrusion into the house due to theft of the card or unauthorized use of the device as in the past, giving a sense of security to the family and providing a more secure security system. can do. In addition,
Returning home notification means include, for example, performing on a monitor of a computer (control unit) for controlling the operation of the above-mentioned personal identification machine, and transmitting voice such as "San-no-go" or sounding sound such as a speaker. Can be notified to the family.

In order to solve the above problem, a home security system according to the present invention (claim 3) includes a personal identification device similar to that of claim 1, and determines that the personal identification device is an identification information registrant. The unlock signal output means for outputting a signal for unlocking the entrance door from the personal identification device, and the identification of the registrant registered by the personal identification device to determine who has returned to the family in the house. A return notification means for outputting information to be notified is provided.

In this case, a signal for unlocking the entrance door is output by the personal identification device, and the door is automatically unlocked. Therefore, the system is safe and convenient, and the identification by the return-to-home notification means is made. Before entering a person indoors, the family in the house will be informed of the person who returned,
You will be able to give a sense of security to your family.

[0010] On the other hand, in the home security system, when the person who has been verified by the personal identification device is determined to be an unregistered user, or when the visitor has not been verified by the personal identification device, he or she cannot stay at the entrance for a certain period of time. When staying, a visitor notifying means for outputting information for notifying the family in the house that the visitor is at the entrance can be provided.

[0011] In this case, since the visitor notification means informs the inside of the house that the unregistered person of the identification information is at the entrance, the family inside the house can know the visit of the suspicious person, the visiting seller, and the like. Subsequent actions can be taken accordingly. The visitor notifying means may be visually performed by a display means such as a monitor, for example, or may be output by a sound output means such as a speaker by outputting a sound or a dial tone. The information that the visitor has stayed at the entrance for a certain period of time or more can be adopted, for example, by a method of detecting the visitor by providing a detection sensor (detection means) such as an infrared monitoring camera near the entrance. It is. Further, in this case, it is also possible to project an image near the entrance from the infrared surveillance camera on the monitor. This camera can also be incorporated in the personal identification device described above.

The personal identification device may be provided with an intercom function or a separate intercom may be provided. Specifically, the family (identification registrant) who returned home
For example, a reply message such as "please go home" can be given by the intercom, and it is possible to give a sense of security to those who have returned home.

Further, when an intercom function unit is incorporated in the personal identification device or a separate intercom is provided, and the person who has been verified by the personal identification device is determined to be an unregistered identification information person, A control means for activating the intercom function unit or the intercom can be provided.

In this case, for example, a computer (control unit) for controlling the operation of the personal identification device can be used as the control means. Specifically, for example, a response message such as "Where are you?" Can be automatically sent to an unregistered user (visitor) by an intercom. In response to this message, the visitor can make a reply message such as "Is" to the intercom, and the message is sent indoors. As a result, the family in the house can know who the visitor is and can take appropriate measures thereafter.

If the visitor stays in front of the personal identification device for a certain period of time or longer, a visitor notification system for automatically issuing a message such as "Touch the button" may be introduced. it can. This visitor notification system may employ a method of writing in the vicinity of the personal identification device by a posting means in advance.

It should be noted that in addition to entering the house, personal identification is performed when leaving the house, and entry / exit history storage means for storing entry / exit to the house for each person is provided. For example, by checking the entry / exit history storage means, it is possible to instantly grasp the presence or absence of the whole family at home. Further, it is also possible to enable the information on the presence or absence at home to be confirmed by a communication means such as a telephone from outside.

[0017]

Embodiments of the present invention will be described below with reference to embodiments shown in the drawings. FIG. 1 is a schematic diagram showing one embodiment of a house in which the home security system of the present invention has been introduced. In the house 100,
Entrance door 2 with a personal identification device is provided so that only persons registered in advance by collating identification information of fingerprints and ID numbers are permitted to pass. Entrance door 2 with personal identification machine
The identification information described later is registered in advance in the personal identification device provided in the device, and it is determined whether or not the user is a registrant by collation with the actually input identification information.

The entrance door 2 with a personal identification device is a house 100
The control is performed by a control unit 1 provided inside, and the monitoring camera 3 and the intercom 4 also provided at the entrance are controlled by the control unit 1. The surveillance camera 3 is an infrared surveillance camera as a visitor detecting unit that projects an image near the entrance on a monitor of the control unit 1 and further includes an infrared sensor that detects a visitor to the entrance. Also,
The intercom 4 is used not only for a general calling function but also for outputting a voice and a dial tone recorded in advance based on the judgment of the personal identification device, or for inputting or outputting a voice inside and outside the house. .

FIG. 2 is a block diagram showing a system configuration of a home security system 200 including the above devices. A control unit 1 for controlling each device of the home security system 200 is provided in the house. The control unit 1 includes a CPU 1a, a ROM 1b, a RAM 1c, and an I / O port 1d. When it is determined that the person who has performed the collation by the personal identification device 5 is the identification information registrant (family),
Based on the collation, a monitor 8 and / or a loudspeaker (such as a speaker) 8 'for notifying the family in the house of "who returned home" are provided. Specifically, a name or the like is displayed on the monitor 8 together with a dial tone from the control unit 1 (returnee notification means), or the name of the returnee is output from the speaker 8 ′, or And the name of the returnee is output from the speaker 8 '. In short, as the returnee notifying means, in addition to the method of displaying the name of the returnee on the monitor as in the present embodiment, the control section 1 or the like emits a voice or a dial tone, and the voice or the dial tone or the like. , A method of notifying the family in the house who has returned can be adopted.

The monitor 8 displays the fact that "visitor visits" to family members in the house when it is determined that the person who has collated by the personal identification device 5 is a person who has not registered identification information (such as a visitor). It also has a function as a visitor notification means for notifying the user. As the visitor notifying means, other than the monitor 8, a method of notifying the family in the house of the visitor's visit to the family in the house by the voice / sound tone from the control unit 1 or the like can be adopted as described above. Note that the RAM 1c stores synthesized sound data (for example, “Mama is back”) for each of the identification information registrants (family), and a voice for returning home notification that stores the synthesized sound data. A data memory 1f can be provided.

The ROM 1b of the control unit 1 includes a personal identification device 5
An application program for instructing each device provided at the entrance to open / close the electric lock 6, transmit the intercom 4, and operate the display device 10 based on the collation result, and an operation program for operating the application And are provided. In addition, R of the control unit 1
The AM 1c has a required memory area (for example, the above-described voice data memory 1f) in addition to the entry / exit history memory 1e as entry / exit history storage means for storing the history of all the family members who have entered / exited the room by collation with the personal identification device 5. Is secured. By referring to the entry / exit history storage means, the occupancy status of the family can be confirmed. For example, the entry / exit history memory 1e is a map as shown in FIG. 3, and for each family member, the entry / exit history flag is discriminated, that is, the family entry is determined by the entry / exit history ○ (occupied), x (absent) flag. You can check the occupancy status. The entry / exit history is collated by the personal identification device, and when entering / exiting, the ○ and × flags are rewritten.

On the other hand, on the entrance side, on the entrance door 2 with a personal identification device, a display device 10 for displaying the collation result of the personal identification device 5 and an electric lock 6 for opening and closing the door in response to the collation result. And are provided. In addition, the personal identification device 5
The command from the control unit 1 based on the collation result of
A single door control board 7 to be executed by the display device 10 or the like is provided on the entrance side, and the single door control board 7 includes the intercom 4 and the personal identification device 5, the electric lock 6, the display device 10
It functions as a driver that governs the operation of. The monitoring camera 3 is connected to the control unit 1, and its operation is controlled by the control unit 1. The display device 10 can be omitted. Further, it is also possible to directly transmit a single command signal for opening and closing the electric lock to the door control board 7 from the personal identification device 5. For example, the personal identification device 5 incorporates an unlocking signal output means and an IC chip as unlocking means,
The door can be unlocked by transmitting the unlocking signal to the driver of the electric lock. When the single door control board 7 unlocks the electric lock, an unlock signal is transmitted from the personal identification device 5 (unlock signal output means) to the single door control board 7.

The outgoing voice and the outgoing sound from the intercom 4 are registered in advance in the outgoing sound storage section in the intercom 4, and various messages are registered and recorded. First, a response message for the registrant when the personal identification device 5 confirms that the registrant has returned home. Second, a response for the non-registrant when the personal identification device 5 confirms the visit of an unregistered person. Messages, thirdly, notification messages to those who stay at the entrance for a certain period of time without inputting to the personal identification device 5, and fourthly, warning messages for prompting exit from the entrance are registered and recorded. .

Specifically, the reply message for registrants is "Go home," etc. The reply message for non-registrants is "Who are you?""And the like can be registered and recorded as a warning message such as" I cannot do so. " In addition, this intercom 4
Is switched to an operation state by the control unit 1 in accordance with information from the personal identification device 5 and the monitoring camera 3 on the entrance side, and each message is sent. Although the above messages are registered and recorded in advance by synthetic sounds, they can be newly recorded at each home with a child's voice or the like.

On the other hand, the personal identification device 5 is provided with an identification information storage unit in which identification information such as a registrant's fingerprint is registered in advance, and the personal identification device 5 refers to the identification information storage unit to actually input the identification information. The collation with the identification information is performed.
Note that the identification information can be registered in the identification information storage unit by inputting the identification information in the control unit 1 and distributing the identification information to the personal identification device 5 from the control unit 1.

As shown in FIG. 4, the passage of the entrance door is permitted by collation of the personal identification device 5, and the personal identification device 5 in this embodiment is as shown in FIG. The personal identification unit 20 is used. The fingerprint identification unit 20 includes a numeric keypad 23 and a fingerprint identification device 22, and the passer-by A enters the ID number with the numeric keypad 23,
A finger is put on the fingerprint recognition unit 21 of the fingerprint identification device 22 to input a fingerprint. In addition, it is also possible to use the personal identification device 5 having only the numeric keypad 23 and the fingerprint identification device 22, and it is also possible to adopt a device using identification means such as a retina and a card. The numeric keypad 23 is provided because the fingerprint information of the individual is stored in association with the ID number of the individual. When the ID number is input by the numeric keypad 23, the fingerprint information corresponding to the ID number is compared. The fingerprint information is confirmed as one (registered fingerprint information), and the actually input fingerprint information is used as the other, and the two are compared (match determination). Note that since it is assumed that the ID number is correct as a premise of fingerprint collation, it can be said that the result is a double check of the ID number and the fingerprint.

Although the fingerprint collation method is a known technique, its contents will be briefly described. There are various methods for fingerprint identification, for example, a feature point extraction method can be adopted. In the feature point extraction method, first, feature points such as an end point and a branch point of a fingerprint, which are generally said to be about 200 for a human, are extracted from a fingerprint image, and the image data is stored. The method of extracting feature points is performed by capturing a scanned image with a sequence of digital lines and thinning the pixels of such a sequence. That is, the number of linked point sequences is calculated,
For example, when the number of links is 0, it can be eliminated as an isolated point (noise), and when the number of links is 1, it is extracted as an end point of a feature point,
When the number of links is 3, neighboring pixels are extracted as branch points of the feature points. If the number of links is 2, the link is a connecting line (not a feature point) and is not extracted as a feature point.
In the above case, it is an intersection and is not extracted as a feature point. Image data is stored for each feature point in such a manner. On the other hand, similar feature point extraction is performed on the input image, and a plurality of (e.g., eight) feature points are extracted therefrom.
It is determined whether or not it matches the feature point of the stored image data. In the determination method, at a certain feature point (for example, a branch point), stored registered image data is compared with input image data of an input branch point by a specific algorithm, and a threshold value (for example, the total number of pixels) is determined. 8 of
If the number of matching pixels is equal to or more than 0%), it is determined that the feature points match. Then, when a certain value (for example, three) or more of the plurality of (for example, eight) feature points extracted from the input image is determined to be the same, the fingerprint matching is determined. In the feature point extraction method, it is said that, for example, if about 12 or more out of about 200 feature points match, a matching match may be made.

On the other hand, it is also possible to use a retinal discriminator 12 as shown in FIG. The retinal discriminator 12 includes a numeric keypad 12b and a retinal detecting unit 12a.
The number is entered by key, and the retina is detected and input to the retina detecting unit 12a. This is because the ten key 12b in this case also stores the individual's retinal information in association with the individual's ID number, and when the ID number is input by the ten key 12b, the retinal information corresponding to the ID number is compared. One of them (registered retinal information) is recognized, and the other is compared (match determination) with the actually input retinal information as the other. Again, ID is assumed as a prerequisite for retinal verification.
Since it is necessary to input the number correctly, it can be said that the result is a double check of the ID number and the retina.

Although the retina matching method is also a known technique, its content will be briefly described. First, for example, light is generated by a pulse-biased direct current (eg, 5 V) incandescent tungsten lamp, and a predetermined lead angle is set around the pupil of the eye.
A spiral near-infrared ray that rotates at (for example, 10.3 degrees) is formed in a cylindrical shape. This weak light passes through the iris and is reflected and absorbed by the retinal vascular pattern, which differs for each individual. The reflected light returning to the same light emission path hits the beam splitter, travels to the detector, is analyzed by the detector, and becomes an analog signal that is the basis of retinal pattern data. The signal detection device converts analog signals to A / D
The signal is sent to a converter where it is digitized and processed into, for example, 96 bytes of pixel data and stored in a file. At the time of registration, for example, five measurements are performed to ensure more reliable reproducibility, and the average value is registered data. When the reading operation after registration is performed in the same manner, the A / D converter sends a digital signal to the comparator, and a specially programmed search algorithm uses the registration data stored in the nonvolatile memory and the input data at the time of identification. Check if matches. Actually, if the input data input and the stored registration data have the number of matching pixels equal to or more than a threshold value (for example, 80% of the total number of pixels), it is determined that the retinal collation matches. I do. In such a retinal discriminator, the data is stored in a small memory of, for example, 96 bytes, so that the misrecognition rate at the time of personal discrimination is extremely low, and has a high accuracy of about once per million or less. In this way, individual identification by the retina has low instability factors and biological features are held in the eyes and cannot be seen from the outside,
It is also free from issues such as forgery, loss, and theft.

FIG. 7 shows a configuration example of each device of the home security system 200 as described above. A display device 10 and an electric lock 6 are provided in a single door, and an individual An identification device 5, an intercom 4, and a monitoring camera 3 are provided.

Hereinafter, the home security system 20 will be described with reference to FIG.
0 will be described. First, when a key and a fingerprint as identification information are input to the personal identification device 5 in S1 of FIG. 8, the process proceeds to S4, where the matching with the registered identification information is performed. If the matching of the identification information is confirmed and the individual is identified, the information of the identified individual is sent to the monitor 8 and / or the loudspeaker 8 'in the house by a name or the like, together with the dial tone from the control unit 1 in S6. Is output. Subsequently, a message such as "go home" is sent from the intercom 4 in S7, and then the electric lock 6 is unlocked in S8, and the registrant (family) is allowed to enter the house (S9). .

On the other hand, if the identification information is not input to the personal identification device 5 in S1, the process proceeds to S2, and the visitor does not input the identification information to the personal identification device 5 for a predetermined time (for example, 10 minutes).
Seconds) A check is made to see if you have stayed at the entrance for more than a second. If the visitor stays for more than a predetermined time, visitor stay processing is performed in S3.

In the visitor stay process, as shown in FIG. 9, first, in S301, the fact that the visitor will stay at the entrance is displayed on the monitor 8 in the house and / or outputted from the speaker 8 '. At this time, it is assumed that the control unit 1 simultaneously emits a dial tone. Subsequently, in S302, the image from the monitoring camera 3 is displayed on the monitor 8, so that the situation of the entrance and the person image of the visitor can be confirmed to the family in the house.

Further, in S303, the intercom 4
, A message such as "Touch the button (fingerprint recognition unit 21)" is played, and in S304, it is confirmed again whether the identification information has been input to the personal identification device 5. When the identification information is input, the process proceeds to S4 in FIG. 8, and the following process is continuously performed. On the other hand, if the identification information has not been input in S304, a message such as "I cannot make an inquiry" is sent in S305. In addition, if the visitor continues staying by the message, an alarm sound can be sounded.

On the other hand, if it is determined in S4 of FIG. 8 that the person has not been registered by the personal identification device 5, the process proceeds to S5, in which an unregistered person visit process is performed. In the unregistered person visit process, as shown in FIG. 10, first, in S501, the fact that an unregistered person has visited is displayed on the monitor 8 in the house and / or output to the speaker 8 '. At this time, it is assumed that a tone for visiting an unregistered person is played from the control unit 1 at the same time.
Subsequently, in S502, the video from the monitoring camera 3 is displayed on the monitor 8, so that the situation of the entrance and the person image of the visitor can be confirmed to the family in the house.

Next, in S503, a message such as "Where are you?" Is sent from the intercom 4, and the visitor responds to "Yes" (S504). In response to the visitor's response in S504, the controller 1 can make various responses from the house in S505. For example, when the electric lock 6 is unlocked or when it is not desired to respond to a visitor, a message such as "I cannot make a call" can be sent.

In the home security system 200 having the above configuration, the identification information is collated by the personal identification device 5 and the notifying means (the control unit 1 and the monitor 8) for notifying the collation result to the house is provided. The indoor family can know in advance the personal information of the identified person or the visit of an unregistered person. In addition, since all operations are automatically performed by the control unit 1 and each message is also automatically transmitted, the family may monitor the response to the visitor by the notification means, and finally, the operation such as opening and closing the electric lock. Only to do. Thus, a sense of security can be given to the family, and a more secure and convenient security system can be provided. In addition, since personal identification is performed using a fingerprint that is a biological feature as identification information, it is possible to prevent unauthorized intrusion due to theft of a card or ID number as in the related art. Further, the vicinity of the entrance is monitored by the surveillance camera 3, and when the visitor stays at the entrance for a certain period of time or more, the visitor staying process is performed.

On the other hand, since all the above operations are automatically performed by the control unit 1, convenience is added to safety. It should be noted that each of the above messages and the like can be appropriately selected and flown by the family by operating the control unit 1 in the house.

The fingerprint recognition unit 21 of the personal identification device 5
It is also possible to adopt a button-shaped one that doubles as a doorbell button, in this case, at the same time the doorbell is flushed into the house,
Fingerprint identification will be performed, and visitors will be able to use the device without realizing it as a fingerprint identification device.

Further, a visitor storage means is provided in the control section 1 so that the visitor B who has once inputted identification information (fingerprint or the like) by the personal identification device 5 can be stored together with visitor information such as a name. In this case, when the visitor B touches (inputs) the personal identification device 5 at the next visit of the visitor B, the corresponding visitor information is displayed on the monitor 8 by referring to the visitor storage means. Or, it can be notified inside the house by voice, dial tone, etc. (visitor return notification means).

It is also possible to use the personal identification device 5 shown in FIG. 7 as a door unlocking means for a family and the intercom 4 as a voice receiving and transmitting means for a customer. In this case, since the personal identification device 5 is used only by the family who is the registrant, it is preferable to install the personal identification device 5 in a place near the entrance that is difficult for others to see, for example, in a place different from the intercom 4 and in a shadow. . Further, the intercom 4 can be operated independently without being connected to the control unit 1, and can respond to the visitor in a normal conversation style using the intercom. In such a system, the family uses the personal identification device 5
Is unlocked by the above operation, the fact is transmitted to the control unit 1, and the control unit 1 notifies the monitor 8 and / or the speaker 8 'of the return of the family (for example, father) to the house. On the other hand, when a visitor presses a doorbell button provided on the intercom 4, a sound such as a voice or a chime sounds inside the house, and the visitor is notified inside the house to be able to respond in a normal conversation style. It has been.

Further, in the home security system of the present invention, a personal identification device 60 with an interphone function shown in FIG. 11 in which the personal identification device 5 and the intercom 4 shown in FIG. 7 are integrated can be introduced. This personal identification machine 6
0 is a surveillance camera 61 (a built-in infrared sensor is also possible), a speaker 62 as an intercom function unit for receiving and transmitting indoor and outdoor sounds, a microphone 62 'for inputting sounds, and And a touch switch (identification unit) 64 for detecting personal identification information such as a fingerprint. Note that the notification monitor 63 of the present embodiment includes a touch switch 6
It is described that 4 is to be touched for more than 1 second. When such a personal identification device 60 is used, when someone touches the touch switch 64, fingerprint matching is performed following fingerprint detection. As a result of the collation, when it is determined that the user is the identification information registrant (family), the collation result is transmitted to the control unit 1,
The control unit 1 sends a message for responding to the returning home such as “Go home for dad” from the speaker 62 of the personal identification device 60 and unlocks the electric lock 6. On the other hand, as a result of the collation, when it is determined that the user is an unregistered user of the identification information (a visitor), the collation result is transmitted to the control unit 1, and the control unit 1 operates a switching unit for putting the intercom into an operating state. Personal identification machine 6
0 functions as an intercom. For example, the speaker 62 can transmit and receive to and from the intercom speaker in the house, so that it can take a normal conversation form, or a message for a visitor such as "Where are you?" .

The example shown in FIG. 11 is a personal identification device which also serves as a call button (switch) of the intercom and has an identification portion for identification information such as a fingerprint. And
As shown in the flowchart of FIG. 13, someone touches the touch switch 64 (S10), and performs personal identification such as fingerprint collation in a short time while touching the touch switch 64 (S11). Family, etc.), the unlocking (S13) and returning home notification (S14) flows as described above.
If it is not a registrant in S12, the intercom function can be activated in S15. In this case, the announcement "Which is yours" may be reproduced as described above, or a ringing tone is output from the speaker 62 in the same manner as a normal intercom without any announcement, and transmitted to the house. After that, it will be possible to exchange information via the intercom inside and outside the house. In this case, as is well known, there is an internal intercom in the house, which is also equipped with a microphone and a speaker, so that it is possible to talk (transmit / receive) with the external interphone (the microphone of the internal interphone). The input is provided as the speaker output of the external interphone, and the microphone input of the external interphone is provided as the speaker output of the internal interphone).

As such a personal identification device with an intercom function, a personal identification device 70 as shown in FIG.
Can also be used. This personal identification device 70 has the same monitoring camera 71 and speaker 7 as the personal identification device 60 described above.
2. In addition to the monitor 73 and the touch switch 74, a ten key 75 is provided. In this case, the ID number is input to the numeric keypad before personal identification information such as a fingerprint is detected, so that the time required for personal identification is reduced. That is, by inputting the ID number, identification information such as a fingerprint stored in association with the personal ID number is confirmed as one of the comparisons (registered identification information), and the actually input identification information is compared with the other. As a result, a comparison (match determination) between the two is performed, and a quick collation process is performed.

It is to be noted that which finger to use on which side is used for fingerprint comparison in advance between registrants such as family members (for example, the right index finger or thumb). Here, for example, the right index finger is determined. If a visitor who is not registered touches the touch switch (touch panel) with his right thumb,
In the first place, since there is no registration of the fingerprint of the thumb, it does not match the collation and it can be determined that the user is not registered. Further, even if the visitor touches the right index finger, the fingerprint is not registered in the same manner, so that the matching is not performed and it can be determined that the user has not registered. In other words, no matter which finger is touched, the collation will not match, and the operation will be performed in the intercom mode thereafter.

Also, instead of a touch panel (switch) that only touches a finger, the surface of a switch (button) that is actually pressed is used as an identification unit (input / capture unit) for a fingerprint or the like.
While pressing for a certain period of time (for example, about 1 to 3 seconds),
An intercom / personal identification device that identifies and verifies fingerprints may be used.
