Description

The present invention relates to a technique for associating a user with a mobile terminal owned by the user.

Conventionally, devices that perform personal authentication of users using biometric information have been put into practical use in various fields. For example, the automatic ticket gate described in Patent Document 1 authenticates whether or not the user is the owner of the ticket medium used when entering the ticket gate passage by face recognition. This automatic ticket gate blocks the passage of the user through the ticket gate unless the user can be authenticated as the owner of the ticket medium used. In addition, some well-known automated teller machines (ATMs) authenticate whether or not the user is the owner of the cash card accepted by the user using biometric information such as a fingerprint. ATMs prohibit the execution of various transactions (withdrawal transactions, etc.) unless the user can be authenticated as the owner of the used cash card.

The above-mentioned automatic ticket gates, ATMs, and other automatic machines ensure security against unauthorized use of media by others by authenticating whether or not the user is the owner of the medium (ticket medium, cash card, etc.). ing.

Japanese Unexamined Patent Publication No. 2013-191173

However, for example, the automatic ticket gate of Patent Document 1 has a wireless communication unit (proximity type wireless communication unit) in which the wireless communication area is within a range of several cm from the antenna, and the user holds it in the wireless communication area ( Accepts the presented IC card (contactless IC card). The automatic ticket gate 1 acquires the biometric information of the user holding the IC card in the wireless communication area, and authenticates whether or not the user is the owner of the medium presented this time.

Further, a well-known ATM accepts an IC card (contact type IC card) inserted (presented) by a user into a card insertion slot. The ATM acquires the biometric information of the user who has inserted the IC card into the card insertion slot, and authenticates whether the user is the owner of the medium presented this time.

As described above, the conventional automatic machine is an operation of presenting a medium (for example, an operation of holding the above-mentioned non-contact type IC card in the wireless communication area, an operation of inserting the contact type IC card into the card insertion slot. ) Was done by the user. There is a demand for such a conventional automatic machine to eliminate the operation of presenting a medium by the user and improve the operability of the user.

An object of the present invention is to provide a technique for improving operability of a user without deteriorating security against unauthorized use by another person.

The reception unit of the present invention is configured as shown below in order to achieve the above object.

The short-range wireless communication unit receives an identification user code from a mobile terminal located in the wireless communication area in short-range wireless communication. The short-range wireless communication referred to here may be, for example, any one that can cover a range in which the distance from the antenna is about 10 to 20 m as a wireless communication area. Standards for this type of short-range wireless communication include Bluetooth (registered trademark) and ZigBee (registered trademark).

The biometric information acquisition unit acquires biometric information of a user located in the wireless communication area. For example, the biometric information acquisition unit acquires a frame image of the user's face as the user's biometric information. The collation code generation unit extracts the feature amount of the biological information acquired by the biometric information acquisition unit, and generates a collation user code based on the extracted feature amount.

The matching unit collates the collation user code with the identification user code, and associates the user whose biometric information has been acquired by the biometric information acquisition unit with the mobile terminal that has received the identification user code. Further, the identification user code is a code generated by the same logic as the logic in which the collation code generation unit generates the collation user code.

According to this configuration, the user is associated with the mobile terminal owned by the user by collating the biometric information. Therefore, a user who illegally possesses another person's mobile terminal is not associated with another person's mobile terminal. That is, the security against unauthorized use of the mobile terminal by another person is not reduced. In addition, the user can be associated with the mobile terminal owned by the user without performing an operation such as presenting the mobile terminal. Therefore, the user does not need to take out the mobile terminal from the bag, pocket, or the like. Therefore, the operability of the user can be improved.

Further, when the associating unit receives the identification user code from a plurality of mobile terminals, the degree of similarity with the collation user code is equal to or higher than the threshold value for the user whose biometric information is acquired by the biometric information acquisition unit. In addition, it is preferable to configure the configuration so as to correspond to the mobile terminal that has transmitted the maximum identification user code. That is, the associating unit is configured so that the user who has not received the identification user code whose similarity with the collation user code is equal to or higher than the threshold value is not associated with any mobile terminal. preferable. With this configuration, when the user who acquired the biometric information does not own the mobile terminal, this user is erroneously associated with the mobile terminal owned by another user located in the wireless communication area. Can be prevented.

Further, the automatic machine according to the present invention includes the above-mentioned reception unit and a processing unit in which the biometric information acquisition unit executes processing for the user who has acquired the biometric information. Further, the short-range wireless communication unit receives the appropriateness determination information used for determining the appropriateness of the user from the mobile terminal by the short-range wireless communication, and the processing unit further receives from the mobile terminal associated with the user. The processing content of the processing to be executed for the user is selected by using the appropriateness judgment information.

For example, when this automatic machine is an automatic ticket gate, the short-range wireless communication unit receives the ticket information as appropriate judgment information from the mobile terminal, and the ticket information received by the processing unit is used to process the ticket gate for the user. To execute.

When the automatic machine is a payment device, the short-range wireless communication unit receives payment information as appropriate determination information from the mobile terminal, and the processing unit uses the received payment information to settle the transaction amount.

Further, when this automatic machine is an ATM, account information is received by the short-range wireless communication unit as appropriate determination information from the mobile terminal, and the deposit / withdrawal transaction is executed using the account information received by the processing unit.

The automatic teller machine is not limited to the above-mentioned automatic ticket gates, payment devices, and ATMs, and may be other types of devices.

According to the present invention, the operability of the user can be improved without lowering the security against unauthorized use by another person.

Hereinafter, embodiments of the present invention will be described.

<1. Application example>
FIG. 1 is a schematic view of the area around the ticket gate of a station where an automatic ticket gate is installed. In this example, the automatic ticket gate 1 corresponds to the automatic machine referred to in the present invention.

The automatic ticket gate 1 has an entrance ticket gate unit 1a and an entry ticket gate unit 1b arranged so as to face each other across the ticket gate passage 111. The traffic direction of the user 100 (100a, 100b) in the ticket gate passage 111 is bidirectional (the direction of entering the station yard and the direction of exiting from the station yard). The automatic ticket gate 1 performs ticket gate processing for the user 100 who enters the station yard and the user 100 who enters from the station yard.

Further, as will be described in detail later, the automatic ticket gate 1 includes a reception unit referred to in the present invention.

The user 100 carries his / her own mobile terminal 5 (5a, 5b). The mobile terminal 5 is, for example, a smartphone or a tablet terminal. The mobile terminal 5 includes a short-range wireless communication unit that performs short-range wireless communication with a partner station. The short-range wireless communication unit may cover a range of about 10 to 20 m as a wireless communication area centered on the main body of the mobile terminal 5. Standards for this type of short-range wireless communication include Bluetooth (registered trademark) and ZigBee (registered trademark).

FIG. 1 distinguishes between a user 100a who has entered the ticket gate passage 111 and a user 100b (a user 100b who has not entered the ticket gate passage 111) in the vicinity of the automatic ticket gate 1. Further, the mobile terminal 5a owned by the user 100 who has entered the ticket gate passage 111 and the mobile terminal 5b owned by the user 100b in the vicinity of the automatic ticket gate 1 are distinguished.

The mobile terminal 5 has a terminal ID that identifies the own terminal, an identification user code that indicates the amount of facial features of the owner of the own terminal, and ticket information that indicates the contents of the ticket held by the owner of the own terminal. I remember. The ticket information includes commuter pass information (valid period, valid section, etc.), SF (Stored Fare) ticket information (prepaid balance, etc.), boarding history information, etc., and includes information stored in a well-known transportation IC card. Equivalent.

The user 100 may hold the mobile terminal 5 in his / her hand, may put the mobile terminal 5 in a pocket of clothes, or may put the mobile terminal 5 in a bag or the like which is baggage.

The automatic ticket gate 1 performs wireless communication with a mobile terminal 5 located in the communication area 110 of short-range wireless communication. That is, the automatic ticket gate 1 is provided with a short-range wireless communication unit that performs short-range wireless communication with the mobile terminal 5. The automatic ticket gate 1 reads the information stored in the mobile terminal 5 and writes the information to the mobile terminal 5 by short-range wireless communication with the mobile terminal 5.

When the automatic ticket gate 1 of this example detects that the user 100 has entered the ticket gate passage 111, the automatic ticket gate 1 acquires an identification user code from each mobile terminal 5 located in the communication area 110 of short-range wireless communication. For example, in the example shown in FIG. 1, the automatic ticket gate 1 acquires an identification user code from six mobile terminals 5.

Further, the automatic ticket gate 1 acquires a frame image obtained by capturing the face of the user 100 who has entered the ticket gate passage 111 with a camera. The automatic ticket gate 1 processes the acquired frame image of the face of the user 100 and generates a collation user code. This verification user code is a code generated based on the facial features of the user 100 who has entered the ticket gate passage 111.

The identification user code stored in the mobile terminal 5 is a code generated by processing a frame image obtained by capturing the face of the owner of the mobile terminal 5. The identification user code is generated by the same logic as the logic in which the automatic ticket gate 1 generates the verification user code.

The automatic ticket gate 1 collates the verification user code generated this time with the identification user code received this time, and calculates the degree of similarity thereof. This similarity is calculated for each identification user code received this time. The automatic ticket gate 1 determines whether or not the calculated maximum value of similarity is equal to or greater than a preset threshold value. If the maximum value of this similarity is less than a preset threshold value, the automatic ticket gate 1 sets the user 100 who has entered the ticket gate passage 111 this time as a non-ticket person (user 100 who does not have a ticket). It is determined that the user 100 is prohibited from passing through the ticket gate passage 111. For example, the automatic ticket gate 1 closes a door provided on the exit side of the ticket gate passage 111 for the user 100 who is determined to be a non-ticket person.

Further, if the calculated maximum value of the similarity is equal to or higher than the preset threshold value, the automatic ticket gate 1 refers to the user 100 who has entered the ticket gate passage 111 this time as the identification user having the maximum similarity. Corresponds to the mobile terminal 5 that has sent the code. That is, in the automatic ticket gate 1, the user 100 who has entered the ticket gate passage 111 this time possesses the mobile terminal 5 that has transmitted the identification user code having the similarity equal to or higher than the threshold value and having the maximum similarity. It is determined that the mobile terminal 5 is used.

The automatic ticket gate 1 acquires the ticket information from the mobile terminal 5 associated with the user 100 who has entered the ticket gate passage 111 this time. The automatic ticket gate 1 determines whether to allow or prohibit the user 100 from passing through the ticket gate passage 111 by using the received ticket information. The automatic ticket gate 1 determines, for example, whether or not a cycle error has occurred, whether or not there is a ticket that allows entry and exit at the station where the automatic ticket gate 1 main body is installed, and the like.

When the automatic ticket gate 1 determines that the user 100 is not allowed to pass through the ticket gate passage 111, the automatic ticket gate 1 closes the door provided on the exit side of the ticket gate passage 111 for the user 100. On the other hand, when the automatic ticket gate 1 determines that the user 100 is allowed to pass through the ticket gate passage 111, the automatic ticket gate 1 opens the door provided on the exit side of the ticket gate passage 111 for the user 100. Further, when the automatic ticket gate 1 determines that the passage of the ticket gate passage 111 is permitted, it requests the mobile terminal 5 associated with the user 100 to update the stored ticket information. The automatic ticket gate 1 requests not only the cycle information but also the update of the residual value of the SF ticket as necessary.

In this way, the automatic ticket gate 1 corresponds to the user 100 and the mobile terminal 5 owned by the user 100 without causing the user 100 who has entered the ticket gate passage 111 to perform a special operation. Can be attached. Further, the automatic ticket gate 1 acquires the ticket information stored in the associated mobile terminal 5 and performs ticket gate processing for the user 100. Therefore, the operability of the user 100 can be improved without lowering the security against unauthorized use by another person.

Further, in the automatic ticket gate 1, the target for authenticating the user 100 who has entered the ticket gate passage 111 with biometric information is several users 100 who own the mobile terminal 5 located in the wireless communication area 110. .. Therefore, in the generation of the collation user code and the identification user code, the extraction of the feature amount may be relatively rough. Therefore, the processing load required to generate the verification user code and the identification user code can be suppressed.

Further, since it is not necessary to provide a server that registers the biometric information of each user 100, the cost for constructing the system can be suppressed.

The control unit 21 controls the operation of the reception unit 12 main body. The control unit 21 has a collation code generation unit 21a and an association unit 21b. Details of the collation code generation unit 21a and the association unit 21b will be described later.

The short-range wireless communication unit 22 wirelessly communicates with the partner station (in this example, the mobile terminal 5). The wireless communication area of the short-range wireless communication unit 22 is a range of about 10 to 20 m centered on the main body of the automatic ticket gate 1.

The imaging unit 23 entered the first camera (not shown) attached at an angle for capturing the face of the user 100 who entered the ticket gate passage 111 and entered the station yard, and the ticket gate passage 111. The user 100 has a second camera (not shown) attached at an angle for capturing the face of the user 100 who participates from the station yard. That is, in this example, the imaging unit 23 has two cameras. The first camera and the second camera may be a still camera that captures a still image or a video camera that captures a moving image. Here, the first camera and the second camera will be described as still cameras for capturing still images. The imaging unit 23 corresponds to the biological information acquisition unit referred to in the present invention.

Next, the collation code generation unit 21a and the association unit 21b of the control unit 21 will be described. The collation code generation unit 21a processes the frame image of the user 100 who has entered the ticket gate passage 111, which is captured by the first camera or the second camera of the imaging unit 23, and features the face of the user 100. Extract the amount. The collation code generation unit 21a generates a collation user code based on the extracted facial features of the user 100.

The association unit 21b enters the ticket gate passage 111 by collating the collation user code with the identification user code acquired by the short-range wireless communication unit 22 by wireless communication with the mobile terminal 5. The person 100 is associated with the mobile terminal 5 owned by the user 100.

The control unit 21 of the reception unit 12 is composed of a hardware CPU, a memory, and other electronic circuits. When the hardware CPU executes the association program according to the present invention, it operates as the collation code generation unit 21a and the association unit 21b. Further, the memory has an area for expanding the association program according to the present invention and an area for temporarily storing data and the like generated when the association program is executed. The control unit 21 may be an LSI in which a hardware CPU, a memory, and the like are integrated. Further, the hardware CPU is a computer that executes the association method according to the present invention.

The user detection unit 13 detects the position of the user 100 in the ticket gate passage 111 at regular time intervals (for example, 100 msec), and tracks the user 100 passing through the ticket gate passage 111. The user detection unit 13 has a plurality of light emitting elements and a plurality of light receiving elements. The plurality of light emitting elements are attached to one of the entrance ticket gate unit 1a or the entry ticket gate unit 1b, and the plurality of light receiving elements are attached to the other of the entrance ticket gate unit 1a or the entry ticket gate unit 1b. The plurality of light emitting elements are arranged in the traffic direction of the user in the ticket gate passage 111. Similarly, a plurality of light receiving elements are also arranged in the traffic direction of the user in the ticket gate passage 111. The light emitting element and the light receiving element have a one-to-one correspondence, and the light emitting element and the light receiving element face each other with the ticket gate passage 111 interposed therebetween.

The user detection unit 13 determines the light receiving element that has not received the light emitted by the light emitting element at regular intervals, and thereby uses the position corresponding to the light receiving element (or the light emitting element) in the ticket gate passage 111. It is detected as the position of the person 100. The user detection unit 13 acquires the change in the position of the user 100 detected at regular time intervals as tracking data of the user 100 in the ticket gate passage 111.

The display unit 14 controls a display (not shown) provided on the entrance ticket gate unit 1a and a screen displayed on the display (not shown) provided on the entry ticket gate unit 1b. The display provided in the entrance ticket gate unit 1a displays a guidance message for the user 100 who enters the station yard. In addition, the display provided in the entry ticket gate unit 1b displays a guidance message to the user 100 who participates from the station yard.

FIG. 3 is a block diagram showing a configuration of a main part of the mobile terminal. The mobile terminal 5 includes a control unit 51, an operation unit 52, a display unit 53, an imaging unit 54, a short-range wireless communication unit 55, and a storage unit 56.

The control unit 51 controls the operation of the mobile terminal 5 main body. The control unit 51 has an identification code generation unit 51a. The identification code generation unit 51a has the same configuration as the collation code generation unit 21a described above.

The operation unit 52 has a touch panel or the like that accepts an input operation by the user 100.

The display unit 53 has a display and controls a screen to be displayed on the display. A touch panel of the operation unit 52 is attached on the screen of this display.

The imaging unit 54 is a camera that captures still images and moving images. The user 100 can generate the user's own identification user code by having the identification code generation unit 51a process the frame image of his / her face captured by the image pickup unit 54.

The short-range wireless communication unit 55 performs short-range wireless communication with the partner station (in this example, the automatic ticket gate 1). The wireless communication area of the short-range wireless communication unit 55 may be large enough to cover a range of about 10 to 20 m centered on the main body of the mobile terminal 5.

The storage unit 56 stores the terminal ID 56a, the identification user code 56b, and the ticket information 56c. The terminal ID 56a is a code for identifying the mobile terminal 5. The identification user code 56b is a code generated based on the facial features of the user 100. As described above, the identification code generation unit 51a processes the frame image of the user's face imaged by the image pickup unit 54 to generate the identification user code. The ticket information 56c is information indicating the contents of the ticket purchased and held by the user 100. In addition, the ticket information includes history information and the like indicating the railway usage history.

A commonly used smartphone, tablet terminal, or the like can be used as the mobile terminal 5 of this example.

<3. Operation example>
Hereinafter, the operations of the automatic ticket gate 1 and the mobile terminal 5 will be described.

First, the identification user code registration process for registering the identification user code 56b in the mobile terminal 5 will be described. FIG. 4 is a flowchart showing the identification user code registration process. The mobile terminal 5 executes this identification user code registration process.

The user 100 operates the mobile terminal 5 owned by the user 100, and images his / her own face (the face of the owner of the mobile terminal 5) with the imaging unit 54. When the mobile terminal 5 captures the face of the user 100 with the imaging unit 54 (s1), the identification code generation unit 51a processes the frame image and extracts the feature amount of the user's face (s2). The identification code generation unit 51a generates the identification user code 56b based on the feature amount extracted in s2 (s3). The mobile terminal 5 stores the identification user code 56b generated in s3 in the storage unit 56 (s4), and ends this process.

The identification user code 56b is used by several people located around the automatic ticket gate 1 (inside the wireless communication area 110 of the automatic ticket gate 1) when the user 100 enters the ticket gate passage 111 of the automatic ticket gate 1. It is sufficient that the user 100 who has entered the ticket gate passage 111 can be authenticated from among the users 100. Therefore, the number of feature points for which the feature amount is extracted in s2 can be suppressed.

Next, the ticket gate processing of the automatic ticket gate 1 will be described. FIG. 5 is a flowchart showing the ticket gate processing of the automatic ticket gate. FIG. 6 is a flowchart showing the ticket processing of the mobile terminal.

The control unit 11 of the automatic ticket gate 1 waits for the user detection unit 13 to detect the entry of the user 100 into the ticket gate passage 111 (s11). Further, the mobile terminal 5 waits for the short-range wireless communication unit 55 to receive the request from the automatic ticket gate 1 (s31). In the short-range wireless communication of the automatic ticket gate 1, the communication area is in a range of about 10 to 20 m centered on the main body of the automatic ticket gate, so that the mobile terminal 5 not located around the main body of the automatic ticket gate 1 can be used. The request from the automatic ticket gate 1 is not received. In other words, the mobile terminal 5 receives the request from the automatic ticket gate 1 when it is located around the main body of the automatic ticket gate 1, that is, around the ticket gate of the station.

When the user detection unit 13 detects the entry of the user 100 into the ticket gate passage 111, the control unit 11 notifies the reception unit 12 of a request for associating the user 100 who has entered the ticket gate passage 111. This notification also includes information indicating whether the user 100 who entered the ticket gate passage 111 this time is the user 100 who enters the station yard or the user 100 who enters from the station yard.

The reception unit 12 captures the face of the user 100 who has entered the ticket gate passage 111 this time with the first camera or the second camera of the imaging unit 23 (s12). If the user 100 who has entered the ticket gate passage 111 this time is the user 100 who enters the station yard, the reception unit 12 captures the face of the user 100 with the first camera of the imaging unit 23. Further, if the user 100 who has entered the ticket gate passage 111 this time is the user 100 who participates from the station yard, the reception unit 12 captures the face of the user 100 with the second camera of the imaging unit 23. Further, the imaging unit 23 captures a plurality of frames (about 3 to 5 frames) of the face of the user 100 who has entered the ticket gate passage 111 this time.

The collation code generation unit 21a selects the best frame image for extracting the facial features of the user 100 who has entered the ticket gate passage 111 this time from the plurality of frame images captured in s12. The collation code generation unit 21a processes the selected frame image and extracts the facial feature amount of the imaged user 100 (s13). The collation code generation unit 21a generates a collation user code based on the feature amount extracted in s13 (s14). The processing related to s13 and s14 is the same as the processing related to s2 and s3 described above, except that the frame image to be processed is different.

Further, the reception unit 12 uses the short-range wireless communication unit 22 to send a request for the identification user code to the mobile terminal 5 (s15). The processing related to s15 may be executed before the processing related to s12 to s14 described above, or may be executed in parallel with the processing related to s12 to s14.

As shown in FIG. 6, when the mobile terminal 5 receives the request from the automatic ticket gate 1 (reception unit 12) (s31), if the request is a request for the identification user code, the storage unit 5 A response including the terminal ID 56a stored in the 56 and the identification user code 56b is sent to the automatic ticket gate 1 (reception unit 12) (s32, s33).

When the reception unit 12 sends a request for the identification user code to the mobile terminal 5 in s15, the reception unit 12 receives a response including the terminal ID 56a and the identification user code 56b from the mobile terminal 5 until a certain period of time elapses. (S16, s17). When the reception unit 12 receives the response including the terminal ID 56a and the identification user code 56b at the short-range wireless communication unit 22, the received identification user code 56b and the collation user code generated in s14 are received. The degree of similarity with is calculated (s18), and the process returns to s16.

The reception unit 12 executes the processes related to s16 to s18, and the identification unit 12 receives the request for the identification user code from the mobile terminal 5 in s15 until a certain period of time elapses. For each user code 56b, the degree of similarity with the collation user code generated in s14 is calculated.

When the reception unit 12 determines that a certain time has elapsed in s16, the association unit 21b determines whether or not the maximum value of the similarity calculated in s18 this time is equal to or greater than a preset threshold value (s19). When the association unit 21b determines that the maximum value of the similarity is not equal to or higher than the preset threshold value, the association unit 21b determines that the user 100 who has entered the ticket gate passage 111 this time is a non-ticket person (s20), and controls that fact. Notify unit 11. When the reception unit 12 determines that the user 100 who has entered the ticket gate passage 111 this time is a non-ticket person, the control unit 11 controls the door opening / closing unit 15 and is located on the exit side of the ticket gate passage 111 for the user 100. Close the door (s27) and return to s11.

Therefore, in the automatic ticket gate 1, if the user 100 who has entered the ticket gate passage 111 does not own (carry) the mobile terminal 5 used as a ticket in this ticket gate system, the user 100 is regarded as a ticketless person. Judgment is made and the passage of the ticket gate passage 111 is prohibited. That is, the automatic ticket gate 1 prevents a non-ticket person from passing through the ticket gate passage 111.

Further, when the association unit 21b determines in s19 that the maximum value of the similarity is equal to or higher than the preset threshold value, the user 100 who has entered the ticket gate passage 111 this time has the maximum similarity. It associates with the mobile terminal 5 that has transmitted the identification user code 56b, and sends a request for the ticket information 56c to the mobile terminal 5 (s21). The short-range wireless communication unit 22 sends a request for ticket information 56c. The association unit 21b waits for a response from the mobile terminal 5 to the request of s21 (s22).

As shown in FIG. 6, if the request received from the automatic ticket gate 1 requests the ticket information 56c, the mobile terminal 5 has the terminal ID 56a stored in the storage unit 56 and the ticket information 56c. A response including and is sent to the automatic ticket gate 1 (s34, s35). In s21, since the request is transmitted to the mobile terminal 5 associated with the user 100 who has entered the ticket gate passage 111 this time, even if the other mobile terminal 5b receives this request, it ignores it.

When the reception unit 12 receives a response in which the terminal ID 56a and the ticket information 56c are associated with each other from the mobile terminal 5 at the short-range wireless communication unit 22, the reception unit 12 notifies the control unit 11 of the terminal ID 56a and the ticket information 56c. .. Does the control unit 11 hold a ticket appropriate for the user 100 who has entered the ticket gate passage 111 this time to pass through the ticket gate passage 111 by using the ticket information 56c notified via the reception unit 12. It is determined whether or not (s23). The processing unit 11a executes the processing related to s23. Similar to the ticket gate processing using known tickets, commuter passes, SF tickets, etc., s23 is a process for determining whether or not the user 100 has a ticket valid for entering and exiting at the station. is there. Further, in s23, the cycle error of the user 100 is also determined (whether or not entry or participation is continuous is determined).

When the automatic ticket gate 1 determines in s23 that it does not have a proper ticket, it closes the door located on the exit side of the ticket gate passage 111 for the user 100 (s27) and returns to s11. Therefore, the automatic ticket gate 1 prohibits the user 100 from passing through the ticket gate passage 111 unless the user 100 who has entered the ticket gate passage 111 holds an appropriate ticket. That is, the automatic ticket gate 1 prevents the user 100 who does not have a proper ticket from passing through the ticket gate passage 111.

Further, when the automatic ticket gate 1 determines in s23 that it holds an appropriate ticket, it executes a ticket information update process (s24).

FIG. 7 is a flowchart showing the ticket information update process for s24. In the automatic ticket gate 1, the processing unit 11a generates the update data of the ticket information 56c and notifies the reception unit 12. The updated data of the ticket information 56c includes the station where the automatic ticket gate 1 is installed, the entry / exit data indicating whether the use this time is entry or exit, and the fare for the use of the railway this time (in the SF ticket). (At the time of participation) etc. are included. The reception unit 12 sends a request for updating the ticket information 56c, including the update data of the ticket information 56c notified from the control unit 11, to the mobile terminal 5 associated with the user 100 in s21 ( s41). The short-range wireless communication unit 22 sends a request for s41.

As shown in FIG. 6, if the request received from the automatic ticket gate 1 requests the update of the ticket information 56c, the mobile terminal 5 updates the ticket information 56c stored in the storage unit 56. Then (s37), the update completion of the ticket information 56c is sent to the automatic ticket gate 1 (s38).

If the processing unit 11a receives the update completion from the mobile terminal 5 within a certain period of time after the reception unit 12 sends the update request for the ticket information 56c in s41, the processing unit 11a enters the ticket gate passage 111 this time. It is determined that the user 100 who has entered is allowed to pass through the ticket gate passage 111 (s42, s43, s44). Further, if the processing unit 11a does not receive the update completion from the mobile terminal 5 within a certain period of time after the reception unit 12 sends the update request for the ticket information 56c in s41, the ticket gate this time. It is determined that the user 100 who has entered the passage 111 is prohibited from passing through the ticket gate passage 111 (s42, s43, s45). In s45, it is determined that a writing error has occurred in the mobile terminal 5.

Returning to FIG. 5, if the processing unit 11a determines in s24 that the user 100 who has entered the ticket gate passage 111 this time is allowed to pass through the ticket gate passage 111, the automatic ticket gate 1 will allow the user 100 to pass through. Open the door located on the exit side of the ticket gate passage 111 (s25, s26) and return to s11. Further, if the processing unit 11a determines in s24 that the user 100 who has entered the ticket gate passage 111 this time is prohibited from passing through the ticket gate passage 111, the automatic ticket gate 1 will prohibit the user 100 from passing through the ticket gate passage 111. Close the door located on the exit side (s25, s27) and return to s11.

As described above, it is not necessary for the user 100 passing through the ticket gate passage 111 to perform an operation of presenting the mobile terminal 5 storing the ticket information 56c to the automatic ticket gate 1. That is, the user 100 can pass through the ticket gate passage 111 without taking out the mobile terminal 5 in his pocket, bag, or the like. Therefore, the automatic ticket gate 1 of this example can improve the operability of the user.

Further, since the user 100 passing through the ticket gate passage 111 is associated with the mobile terminal 5 by using the biometric information, the user 100 illegally possesses another person's mobile terminal 5 and enters the ticket gate passage 111. However, the user 100 is not associated with the mobile terminal 5 illegally possessed by the user 100. Therefore, the security against unauthorized use of the mobile terminal 5 by another person is not reduced.

Since it is not necessary to provide a server that registers the biometric information of each user 100, the cost for constructing the system can be suppressed.
