However, it should be noted that the technical scope of the present invention is not limited to these embodiments, and extends to the invention described in the claims and equivalents thereof.

  FIG. 1 is a schematic diagram for explaining an outline of the biometric matching system 1 according to the present embodiment.

  The biometric matching system 1 shown in FIG. 1 authenticates the users A to E using a biometric image obtained by photographing the faces of the users A to E who are about to enter the security area 10, and gates based on the authentication result. 11 is controlled. The gate 11 is, for example, a flapper gate. A biological image is an example of biological information.

  As shown in FIG. 1, the biometric matching system 1 includes a plurality of portable terminals 100 and a biometric matching device 200. In the biometric matching device 200, a biometric image showing each user's face is registered in advance in association with identification information (mobile terminal ID) such as a telephone number of each user's mobile terminal. Hereinafter, a pre-registered biometric image may be referred to as a registered biometric image. Each portable terminal 100 is carried by each user A to E, and periodically transmits a position signal including the portable terminal ID of each portable terminal and position information indicating the current position of each portable terminal to the biometric matching device 200. ing. On the other hand, the biometric matching device 200 detects the distance between each portable terminal 100 and the biometric matching device 200 based on the position signal transmitted from each portable terminal 100.

  Next, when receiving the registration permission signal via the second wireless communication unit 102, the registration request unit 111 of the mobile terminal 100 causes the terminal imaging unit 106 to photograph the user's face of the mobile terminal 100, and A biological image showing the face is acquired (step S103).

  Next, the registration request unit 111 transmits a registration request signal to the biometric matching device 200 via the second wireless communication unit 102 (step S104). The registration request signal is a signal for requesting registration of the biometric image of the user of the mobile terminal 100 in the biometric matching device 200. The registration request signal includes the identification information (phone number) of the mobile terminal 100 and the user's A biological image is included. The registration request signal is transmitted to the biometric matching device 200 via the above-described SMS server.

  Next, when the registration unit 211 of the biometric matching device 200 receives a registration request signal from the SMS server via the device communication unit 201, the registration permission is given to the telephone number of the mobile terminal that is the transmission source of the received registration request signal. It collates with the telephone number of the portable terminal which is the signal transmission destination (step S105). The registration unit 211 performs collation by determining whether or not the telephone number of the portable terminal that is the transmission source of the registration request signal matches the telephone number of the portable terminal that is the transmission destination of the registration permission signal.

  Next, when the registration unit 211 succeeds in collation, that is, when the telephone number of the portable terminal that is the transmission source of the registration request signal matches the telephone number of the portable terminal that is the transmission destination of the registration permission signal, The biometric image included in the signal is stored as a registered biometric image in the registered biometric image table in association with the portable terminal ID (step S106).

  This completes the operation sequence of the biometric image registration process. Since each user can register a biometric image using the mobile terminal 100 owned by the user, it is not necessary to go to the place where the biometric matching device 200 is installed and perform registration, thereby improving user convenience. It becomes possible. The biometric matching device 200 transmits / receives a registration permission signal and a registration request signal to / from each mobile terminal by an SMS message. That is, the biometric matching device 200 registers a biometric image using the phone number of the mobile terminal. As a result, impersonation by another person is prevented and biometric images of persons other than legitimate users are prevented from being illegally registered.

  FIG. 7 is a diagram illustrating an example of an operation sequence of the mobile terminal position notification process by the biometric matching system 1. Note that the operation sequence described below is based on the programs stored in advance in the terminal storage unit 107 and the device storage unit 207, mainly by the terminal control unit 110 and the device control unit 210, and by the portable terminal 100 and the biometric matching device. It is executed in cooperation with the 200 elements. The operation sequence shown in FIG. 7 is periodically executed every predetermined period (for example, 1 second).

  First, the transmission unit 112 of the mobile terminal 100 acquires position information from the position detection unit 105 (step S201). Note that the transmission unit 112 may periodically acquire position information from the position detection unit 105.

  Next, the transmission unit 112 transmits a position signal to the biometric matching device 200 via the first wireless communication unit 101 (step S202). The position signal includes the portable terminal ID of the portable terminal 100 and position information. The transmission unit 112 may transmit a position signal to the biometric matching device 200 via the second wireless communication unit 102. In that case, the position signal is transmitted to the biometric matching device 200 via the above-described SMS server.

  On the other hand, the receiving unit 212 of the biometric matching device 200 receives a position signal from the portable terminal 100 via the device communication unit 201, and the distance detecting unit 213 is based on the position signal received by the receiving unit 212. And a distance between the biometric matching device 200 are detected (step S203). The distance detection unit 213 calculates the distance between the portable terminal 100 and the biometric matching device 200 from the position information of the portable terminal 100 included in the position signal and the current position of the biometric matching device 200 stored in the device storage unit 207. To do.

  Next, the distance detection unit 213 stores the position information of the mobile terminal 100, the distance between the mobile terminal 100 and the biometric matching device 200, and the current date and time in association with the mobile terminal ID of the mobile terminal 100 in the distance table ( Step S204). When the mobile terminal ID of the mobile terminal 100 is not yet stored in the distance table, the distance detection unit 213 newly stores the mobile terminal ID, the position signal, the distance, and the current date and time in the distance table. On the other hand, when the mobile terminal ID of the mobile terminal 100 is already stored in the distance table, the distance detection unit 213 newly displays the position signal, distance, and current date / time associated with the mobile terminal ID in the distance table. Update the acquired location information, distance, and current date and time.

  In addition, the distance detection unit 213 periodically monitors the distance table and deletes each piece of information related to the mobile terminal ID that has not been updated for a predetermined time (for example, 1 minute).

  Thus, the operation sequence of the position notification process of the mobile terminal is completed. By this operation sequence, the biometric matching device 200 can acquire the latest distance between each portable terminal 100 and the biometric matching device 200.

  FIG. 8 is a diagram illustrating an example of an operation flow of biometric matching processing performed by the biometric matching device 200. The operation flow described below is based on a program stored in advance in the terminal storage unit 107 and the device storage unit 207, mainly by the terminal control unit 110 and the device control unit 210. It is executed in cooperation with the 200 elements. Note that the operation flow shown in FIG. 8 is periodically executed.

  First, the person detection unit 214 waits until a person is detected (step S301). The person detection unit 214 acquires the distance from the person detection sensor 204 to the object reflecting the laser, and determines whether the person is in front of the biometric matching device 200 depending on whether the acquired distance is a predetermined distance (for example, 1 m) or less. It is determined whether or not exists.

  When the person detection unit 214 determines that a person is present in front of the biometric matching device 200 and detects a person, the acquisition unit 215 acquires an input biometric image obtained by photographing the face of the person detected by the person detection unit 214. (Step S302). The acquisition unit 215 causes the device imaging unit 206 to capture the face of the person detected by the person detection unit 214 and acquires the captured image as an input biometric image.

  Next, based on the distance between each mobile terminal 100 and the biometric matching device 200 stored in the distance table, the extraction unit 216 selects the mobile terminal 100 within a predetermined range (for example, 10 m) from the biometric matching device 200. It detects (step S303). In particular, the extraction unit 216 detects two or more portable terminals 100 that are within a predetermined range from the biometric matching device 200.

  Next, the extraction unit 216 determines whether or not the portable terminal 100 exists within a predetermined range from the biometric matching device 200 (step S304).

  When the mobile terminal 100 is within a predetermined range from the biometric matching device 200, the extraction unit 216 determines the operation mode in which the matching unit 217 operates as the first mode (step S305). The operation mode defines a method for collating the input biometric image, and has two types of modes, a first mode and a second mode. The first mode is a mode in which the input biometric image is collated with each registered biometric image associated with the mobile terminal ID of each mobile terminal 100 existing within a predetermined range from the biometric matching device 200. On the other hand, the second mode is a mode in which the input biometric image is collated with each of all the registered biometric images stored in the registered biometric image table.

  Next, the extraction unit 216 performs registration in which the collation unit 217 collates the input biometric image with respect to each registered biometric image associated with the mobile terminal ID of each mobile terminal 100 existing within a predetermined range from the biometric collation device 200. The order of the biological images is determined (step S306). For example, the extraction unit 216 determines the order of the registered biometric images in which the collation unit 217 collates the input biometric images with the registered biometrics associated with the mobile terminal ID of the mobile terminal 100 with a short distance from the biometric verification device 200. The image order. Thereby, since the collation part 217 collates in order from the registered biometric image of the user who exists in the position near the biometrics collation apparatus 200, possibility that collation will be successful in a short time becomes high, and collation will be successful. It is possible to reduce the time until.

  Further, the extraction unit 216 may set the order of the registered biometric images with which the collation unit 217 collates the input biometric images in an order determined based on the attributes of the users of the mobile terminals 100. For example, the extraction unit 216 collates with the registered biometric image of the administrator in the security area 10 before the registered biometric image of the general user. As a result, the administrator of the security area 10 is more likely to succeed in collation in a shorter time, and the administrator who passes through the gate 11 many times due to business or the like can enter the security area 10 smoothly. It becomes possible. Further, the extraction unit 216 may collate with a registered biometric image of a manager such as a general manager or a section manager before the registered biometric image of a general employee. Similarly, the extraction unit 216 may collate with the registered biometric image of the employee before the registered biometric image of the guest. As a result, a person who frequently passes through the gate 11 can smoothly enter the security area 10.

  The processes of steps S307 to S311 are executed according to the order determined in step S306 for each portable terminal 100 existing within a predetermined range from the biometric matching device 200.

  First, the extraction unit 216 registers a registered biometric image associated with the portable terminal ID of the portable terminal 100 to be checked next from registered biometric images stored in the registered biometric image table in the order determined in step S306. Is extracted (step S307).

  Next, the collation unit 217 collates the input biometric image with the extracted registered biometric image (step S308). First, the matching unit 217 extracts feature points representing facial features from the input biometric image. For example, the collation unit 217 extracts edge pixels whose luminance difference from surrounding pixels is equal to or greater than a predetermined value from the input biometric image, and calculates a feature amount based on the position, pattern, and the like of the extracted edge pixels. The collation unit 217 identifies the position of each part based on whether or not the calculated feature amount satisfies a predetermined condition for each part such as the eyes, nose, and mouth, and based on the identified position of each part, Extract feature points such as nose tip and mouth corner point.

  The biometric matching device 200 extracts a feature point from the registered biometric image when the registered biometric image is registered by a similar method, and associates the extracted feature point with the registered biometric image in the registered biometric image table. Remember. Note that feature points in the registered biometric image may be extracted by the matching unit 217 during matching. The matching unit 217 calculates the degree of matching between the corresponding feature points of the feature points extracted from the input biometric image and the feature points extracted from the registered biometric image. The collation unit 217 determines that the input biometric image and the registered biometric image match when the calculated degree is equal to or greater than the predetermined threshold, and determines that the collation is successful. On the other hand, when the calculated degree is less than the predetermined threshold, the collation unit 217 determines that the input biometric image and the registered biometric image do not match, and determines that the verification has failed.

  Next, the collation unit 217 determines whether or not collation of the input biometric image has succeeded (step S309).

  When the collation of the input biometric image is successful, the collation unit 217 notifies the user that the collation is successful using the device display unit 202 or the voice output unit 203, and an open signal for opening the gate 11 is interfaced. The data is transmitted to the gate 11 via the unit 205 (step S310), and a series of steps is completed. When the open signal is received, the gate 11 opens and the user can pass through the gate 11. The gate 11 automatically closes the gate 11 after a predetermined time elapses, and prevents other users who have not been successfully collated from entering the security area 12.

  On the other hand, when the verification of the input biometric image fails, the verification unit 217 determines whether the verification with the registered biometric images corresponding to all the mobile terminals 100 existing within the predetermined range from the biometric verification device 200 is completed. (Step S311). The collation part 217 returns a process to step S307, and repeats the process of step S307-S311, when the registration biometric image which has not yet been collated exists.

  On the other hand, when the collation with all the registered biometric images is completed, the collation unit 217 notifies the user that the collation has failed using the device display unit 202 or the voice output unit 203 (step S312). End the step. In this case, the gate 11 is not opened, and the user cannot pass through the gate 11.

  In step S304, when the portable terminal 100 does not exist within the predetermined range from the biometric matching device 200, the extraction unit 216 determines the operation mode in which the matching unit 217 operates as the second mode (step S313). In this case, the input biometric image is collated with each of all the registered biometric images stored in the registered biometric image table in an arbitrary order.

  Since the processing of steps S314 to S318 is the same as the processing of steps S307 to S312, detailed description thereof is omitted. However, the processing of steps S314 to S318 is executed for all registered biometric images stored in the registered biometric image table.

  It should be noted that the biometric matching device 200 executes the position notification processing of the mobile terminal shown in FIG. 7 and the processing of steps S303 and S304 in FIG. You may determine whether the portable terminal 100 exists in the range. When the extraction unit 216 detects the portable terminal 100 within the predetermined range from the biometric matching device 200 during operation in the second mode, the matching unit 217 operates in parallel in both the first mode and the second mode. . For example, when the apparatus control unit 210 has two CPUs, one CPU sequentially collates the input biometric image with each registered biometric image stored in the registered biometric image table in the second mode. The other CPU collates the input biometric image with the registered biometric image associated with the portable terminal ID of the portable terminal 100 existing within a predetermined range from the biometric matching device 200 in the first mode.

  When the portable terminal 100 is detected within a predetermined range from the biometric matching device 200, when the second mode is simply switched to the first mode, the input biological image is not that of the detected user of the portable terminal 100. In such a case, it is necessary to recheck all registered biometric images from the beginning. The biometric matching device 200 operates in parallel in both the first mode and the second mode, so that when the input biometric image belongs to the user of the detected mobile terminal 100, the biometric matching device 200 performs matching in a short time. Even if it is successful, the collation process can be continued without wasting the collation result so far.

  In addition, when the verification in the first mode fails, the biometric matching device 200 does not notify the user that the verification has failed in step S312, but shifts the process to step S313 and sets the operation mode. You may switch to the second mode. As a result, when the input biometric image is that of the user of the mobile terminal 100 existing within the predetermined range, the collation succeeds in a short time, and when not, the input biometric image is converted to the corresponding registered biometric image. It is possible to make sure that it is verified.

  Further, when the verification in the first mode fails, the biometric matching device 200 does not notify the user that the matching has failed in step S312, but from an input device (not shown) such as a numeric keypad or a keyboard, The mobile terminal ID may be specified by allowing the user to input the mobile terminal ID. In addition, the biometric matching device 200 previously registers second identification information different from the mobile terminal ID, such as the user's name and address, and when the matching in the first mode fails, The mobile terminal ID may be specified by inputting identification information. In addition, when the verification in the first mode fails, the biometric matching device 200 allows the user to input identification information and performs a verification process with the registered biometric image corresponding to the input identification information, and in the second mode. The matching process may be executed in parallel. As a result, if the user can input the identification information in a short time, the verification succeeds in a short time, and even if the user takes a long time to input the identification information, the verification can be completed within a certain time. It becomes.

  As described above, the biometric matching device 200 executes the matching process using only the registered biometric image corresponding to the mobile terminal 100 within the predetermined range, so that the input biometric image and all registered biometric images are There is no need to perform collation, and the collation process can be completed in a short time. If each user owns the portable terminal 100, it is not necessary to input an ID code, present a magnetic card, etc., so that convenience for the user is improved. In addition, the biometric matching device 200 collates the input biometric image with all registered biometric images corresponding to the mobile terminal 100 within the predetermined range. It is possible to prevent collation with only the registered biometric image of the person and failure of collation. In addition, since the biometric matching device 200 can collate the input biometric image and each registered biometric image in parallel, the biometric matching device 200 can collate with other registered biometric images without waiting for a matching result with a specific registered biometric image. It can be executed, and it is possible to speed up the entire matching process.

  Note that the present invention is not limited to this embodiment. For example, the biometric matching device 200 uses a wireless signal transmitted from each portable terminal 100 instead of a position signal including the position information of each portable terminal 100, and the distance between each portable terminal 100 and the biometric matching device 200. May be detected. In that case, the portable terminal 100 further includes a first short-range wireless communication unit, and the biometric matching device 200 further includes a second short-range wireless communication unit. Each of the first short-range wireless communication unit and the second short-range wireless communication unit includes an interface circuit for performing short-range wireless communication according to a communication method such as BLE (Bluetooth Low Energy) (registered trademark), Short-range wireless communication with each other. The first short-range wireless communication unit and the second short-range wireless communication unit are for performing short-range wireless communication according to other communication methods such as Bluetooth (registered trademark), RFID (Radio Frequency IDentification), ZigBee, and the like. An interface circuit may be included.

  In this case, in steps S201 and 202 of FIG. 7, the transmission unit 112 of the mobile terminal 100 transmits a wireless signal to the biometric matching device 200 via the first short-range wireless communication unit. The wireless signal includes the mobile terminal ID of the mobile terminal 100. On the other hand, in step S203, the reception unit 212 of the biometric matching device 200 receives a radio signal from the portable terminal 100 via the second short-range wireless communication unit, and the distance calculation unit 213 receives the radio signal received by the reception unit 212. Based on the above, the distance between the portable terminal 100 and the biometric matching device 200 is detected. For example, when the distance calculation unit 213 receives a wireless signal from the mobile terminal 100, the distance calculation unit 213 determines that the mobile terminal 100 is within a predetermined range from the biometric matching device 200. Alternatively, the distance calculation unit 213 creates a table representing the relationship between the radio wave intensity of the radio signal received from the mobile terminal 100 and the distance between the mobile terminal 100 and the biometric matching device 200 through a prior experiment, The distance between the portable terminal 100 and the biometric matching device 200 may be detected according to the table.

  The biometric matching device 200 uses only a short-distance wireless communication signal as the registered biometric image to be matched with the input biometric image for only the registered biometric image corresponding to the mobile terminal 100 existing in the vicinity of the biometric matching device 200. It becomes possible to narrow down.

  In addition, the biometric matching system 1 may use a sound wave as a radio signal transmitted from each mobile terminal 100. In that case, the portable terminal 100 further includes an audio output unit such as a speaker, and the biometric matching device 200 further includes an audio input unit such as a microphone.

  In this case, in steps S201 and S202 in FIG. 7, the transmission unit 112 of the mobile terminal 100 outputs a sound wave representing the mobile terminal ID of the mobile terminal 100 to the biometric matching device 200 via the voice output unit. The waveform of the sound wave output from each mobile terminal 100 is assigned in advance so as to correspond to the mobile terminal ID of each mobile terminal 100. On the other hand, in step S203, the reception unit 212 of the biometric matching device 200 receives sound waves from the portable terminal 100 via the voice input unit, and the distance detection unit 213 uses the sound waves received by the reception unit 212 based on the sound waves received by the reception unit 212. The distance between 100 and the biometric matching device 200 is detected. For example, when the distance detection unit 213 receives a sound wave from the mobile terminal 100, the distance detection unit 213 determines that the mobile terminal 100 is within a predetermined range from the biometric matching device 200. Alternatively, the distance detection unit 213 creates a table that represents the relationship between the maximum amplitude of the sound wave received from the mobile terminal 100 and the distance between the mobile terminal 100 and the biometric matching device 200 through a prior experiment. You may detect the distance between the portable terminal 100 and the biometric collation apparatus 200 according to a table.

  The biometric matching device 200 can also narrow down the registered biometric image to be matched with the input biometric image to only the registered biometric image corresponding to the mobile terminal 100 existing in the vicinity of the biometric matching device 200 by using sound waves. Become.

  Further, the biometric matching system 1 may control opening and closing of a door having a key instead of the gate 11 such as a flapper gate. In that case, the interface unit 205 of the biometric verification device 200 is electrically connected to a key of the door, and an unlocking signal for unlocking the key or a locking signal for locking in accordance with an instruction from the device control unit 210. To the gate key. In this case, in steps S310 and 317 in FIG. 8, the collation unit 217 transmits an unlock signal to the gate 11 via the interface unit 205. Also in this case, the biometric matching system 1 can appropriately control the user's entry and exit from the security area 10.

  In addition, the biometric matching system 1 may use information other than an image such as a voice print instead of a biometric image as biometric information. In that case, the mobile terminal 100 and the biometric matching device 200 include a terminal voice input unit such as a microphone and a device voice input unit (not shown) instead of the terminal imaging unit 106 and the device imaging unit 206, respectively. The registration unit 211 of the biometric matching device 200 registers the voice print of the user of each mobile terminal input via the terminal voice input unit of the mobile terminal 100 as registered biometric information, and the acquisition unit 215 stores the device voice input unit. The voice print of a specific user input through the user is acquired as input biometric information. And the collation part 217 collates the acquired input biometric information with each registration biometric image. Also in this case, the biometric matching system 1 can appropriately match biometric information while improving user convenience.

  It should be understood by those skilled in the art that various changes, substitutions and modifications can be made thereto without departing from the spirit and scope of the present invention.
