Description

Technical Field

[0001] The present invention relates to a gate device, a server device, an immigration inspection system, a control method for a gate device, and a control method for a server device.

Background Art

[0002] Immigration inspection is carried out at an airport. The immigration inspector compares the face photo attached to the passport with the face of the person in front, and permits the person to enter or leave the country when the face in the passport image matches the face of the person in front.

[0003] In recent years, devices for automatically performing the above immigration inspection have been introduced. For example, the gate device disclosed in Patent Document 1 examines the entry and exit of a person based on the collation result between the face image attached to the passport and the face image of the person standing in front of the gate device.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In the gate device disclosed in Patent Document 1, the user opens the page on which the face image of the passport is described and places the page on the passport reader (scanner) provided in the gate device. The gate device acquires the data necessary for the above collation (one-to-one collation) from the passport reader (see, for example, paragraph

[0035] of Patent Document 1).

[0006] In order to use the gate device disclosed in Patent Document 1, the user has to stop in front of the gate device, open the passport held by himself / herself, and read the information on the opened page through a passport reader to let the gate device read it. However, compelling the user to perform such an operation negates the significance of automatically conducting immigration and exit inspections. That is, with the gate device disclosed in Patent Document 1, the user cannot smoothly complete the immigration and exit inspections without stress.

[0007] The main object of the present invention is to provide a gate device, a server device, an immigration and exit inspection system, a control method for a gate device, and a control method for a server device that contribute to realizing smooth immigration and exit inspections.

[0008] According to a first aspect of the present invention, there is provided a gate device including: an acquisition unit that acquires biometric information of a user subject to inspection; a storage unit that stores the biometric information of the user in association with MRZ (Machine Readable Zone) information described in a machine-readable area of a passport issued to the user; a collation request unit that requests the server device to collate the biometric information of the user subject to inspection; and a control unit that controls the gate so that the user subject to inspection can pass through when successful in reading information from an IC (Integrated Circuit) chip of the passport using the MRZ information identified by the collation.

[0009] According to a second aspect of the present invention, there is provided a server device including: a storage unit that stores biometric information of a user in association with MRZ (Machine Readable Zone) information described in a machine-readable area of a passport issued to the user as gate user information; a collation unit that searches the gate user information using the biometric information of the user subject to inspection received from the gate device and that controls the gate according to the result of the immigration and exit inspection of the user, and identifies the MRZ information corresponding to the received biometric information; and a communication control unit that transmits the identified MRZ information to the gate device.

[0010] According to a third aspect of the present invention, there is provided an immigration inspection system including: a server device that stores biometric information of a user and MRZ (Machine Readable Zone) information described in a machine-readable area of a passport issued to the user as gate user information in association with each other; and a gate device that controls a gate according to a result of immigration inspection of the user. The gate device acquires biometric information of a user to be inspected and transmits the biometric information of the user to be inspected to the server device. The server device searches for the gate user information and identifies the MRZ information corresponding to the received biometric information, and transmits the identified MRZ information to the gate device. When the gate device successfully reads information from an IC (Integrated Circuit) chip of the passport using the received MRZ information, the gate device controls the gate so that the user to be inspected can pass through.

[0011] According to a fourth aspect of the present invention, there is provided a control method for a gate device, which acquires biometric information of a user to be inspected in the gate device, requests a server device that stores the biometric information of the user and MRZ (Machine Readable Zone) information described in a machine-readable area of a passport issued to the user in association with each other to verify the biometric information of the user to be inspected, and controls the gate so that the user to be inspected can pass through when information is successfully read from an IC (Integrated Circuit) chip of the passport using the MRZ information identified by the verification.

[0012] According to a fifth aspect of the present invention, in a server device including a storage unit that stores user biometric information and MRZ (Machine Readable Zone) information described in a machine-readable area of a passport issued to the user as gate user information in association with each other, using the biometric information of a user subject to inspection received from a gate device that controls a gate according to the result of the user's immigration inspection, the gate user information is retrieved to identify the MRZ information corresponding to the received biometric information, and the identified MRZ information is transmitted to the gate device. A control method for the server device is provided.

Mode for Carrying Out the Invention

[0015] First, the outline of one embodiment will be described. The reference numerals in the drawings appended to this outline are for convenience and are appended to each element as an example to assist understanding, and the description of this outline is not intended to be limiting in any way. Also, unless otherwise specified, the blocks shown in each drawing represent a configuration of functional units, not hardware units. The connection lines between the blocks in each figure include both bidirectional and unidirectional ones. The one-way arrow schematically shows the flow of the main signal (data) and does not exclude bidirectionality. In this specification and the drawings, for elements that can be similarly described, duplicate description can be omitted by assigning the same reference numerals.

[0016] The gate device 100 according to one embodiment includes an acquisition unit 101, a collation request unit 102, and a control unit 103 (see FIG. 1). The acquisition unit 101 acquires biometric information of the user subject to examination. The collation request unit 102 requests the server device, which stores the biometric information of the user subject to examination in association with the MRZ (Machine Readable Zone) information described in the machine-readable area of the passport issued to the user, to collate the biometric information. The control unit 103 controls the gate so that the user subject to examination can pass through when it succeeds in reading information from the IC (Integrated Circuit) chip of the passport using the MRZ information specified by the above collation.

[0017] In the immigration control system including the gate device 100, if the biometric information of a user who wishes to use the system in advance is registered in the server device, the user can complete the immigration control by simply bringing the passport into contact with the gate device 100 without opening the passport. As a result, it is possible to realize a smooth immigration control that is highly convenient for the user.

[0018] Specific embodiments will be described in more detail below with reference to the drawings.

[0019] [First Embodiment] The first embodiment will be described in more detail with reference to the drawings.

[0020] FIG. 2 is a diagram showing an example of the schematic configuration of the immigration control system according to the first embodiment. Referring to FIG. 2, the immigration control system includes a plurality of gate devices 10-1 to 10-3 and a server device 20. In the following description, when there is no particular reason to distinguish between the gate devices 10-1 to 10-3, they are simply referred to as "gate device 10". Although three gate devices 10 are illustrated in FIG. 2, it goes without saying that the number of gate devices 10 included in the system is not limited. The immigration control system only needs to include at least one or more gate devices 10.

[0021] The gate device 10 is a device that automatically performs the examination procedures related to the user's immigration. The gate device 10 includes a gate configured to be openable and closable. When the gate device 10 determines that a person located in front of the self-device is holding a valid travel document (passport), it opens the gate and permits the user to pass. In this way, the gate device 10 controls the gate according to the result of the user's immigration control.

[0022] The server device 20 is a device for realizing the immigration inspection by the gate device 10. For example, the server device 20 stores information about users who can use the gate device 10 (hereinafter referred to as gate user information). Specifically, the server device 20 stores the biometric information of the user in association with the information described in the Machine Readable Zone (MRZ) of the passport issued to the user (hereinafter referred to as MRZ information).

[0023] Examples of the biometric information of the user include data (feature amounts) calculated from personal unique physical characteristics such as face, fingerprint, voiceprint, vein, retina, and iris pattern of the pupil. Alternatively, the biometric information of the user may be image data such as a face image or a fingerprint image. The biometric information of the user may be anything as long as it includes the physical characteristics of the user as information.

[0024] The information (MRZ information) described in the MRZ of the passport includes the user's name, nationality, gender, date of birth, passport number, expiration date, etc.

[0025] The gate device 10 and the server device 20 are configured to be able to communicate with each other by wired or wireless communication means. The server device 20 may be installed in the same airport as the gate device 10, or may be installed on a network (cloud).

[0026] [Overview of the Immigration Inspection System Operation] Subsequently, with reference to FIG. 2, the overview of the operation of the immigration inspection system according to the first embodiment will be described.

[0027] Gate user information regarding users of the immigration control system is registered in the server device 20, for example, before the users leave the country. That is, the gate user information is registered in the server device 20 before the day of the users' flight or before departure on the day of the flight. The server device 20 is provided with a database for storing the gate user information, and when user registration is performed, an entry for each user is added to the database. In the following description, the database for storing the gate user information is referred to as the "gate user database". In the gate user database, at least biometric information of one or more users and MRZ information described in the machine-readable area of the passport issued to the at least one or more users are stored in association with each other.

[0028] The user visits the airport (the airport where the gate device 10 is installed) on the day of the flight. After procedures for boarding such as check-in and security check are completed, the user moves to the area (immigration control area) where the gate device 10 is installed.

[0029] When the user arrives at the immigration control area, the user moves towards the gate device 10.

[0030] When the user approaches the gate device 10 (when the distance between the user and the gate device 10 becomes equal to or less than a predetermined distance), the gate device 10 acquires (generates) biometric information from the user. The biometric information acquired by the gate device 10 is the same type of information as the biometric information registered as gate user information in the server device 20.

[0031] The gate device 10 transmits the acquired biometric information to the server device 20. More specifically, the gate device 10 transmits a "verification request" including the acquired biometric information to the server device 20.

[0032] The server device 20 searches the gate user database using the received biometric information as a key and identifies the MRZ information corresponding to the received biometric information. The server device 20 transmits a response (response to the verification request) including the identified MRZ information to the gate device 10.

[0033] When the user arrives at the gate device 10, the user holds the passport on the reader (reader 316 described later) provided in the gate device 10 (touches the passport to the reader). That is, the user touches the passport to the reader of the gate device 10 in the same way as touching a transportation IC card to the card reader at the ticket barrier of the station.

[0034] The gate device 10 attempts to read the information described on the IC chip of the passport via the reader. When the gate device 10 succeeds in reading the information stored in the IC chip using the MRZ information acquired from the server device 20, it determines that the user has the correct passport and opens the gate.

[0035] The user passes through the gate and the immigration inspection is completed.

[0036] As described above, in the immigration inspection system according to the first embodiment, by registering the gate user information in the server device 20 in advance, the user can pass through the gate by touching the passport to the reader without opening the passport.

[0037] Subsequently, details of each device included in the immigration inspection system according to the first embodiment will be described. In the following description, information regarding a person's "face" will be taken as an example of the biometric information registered in the server device 20 for explanation.

[0038] [Server device] FIG. 3 is a diagram showing an example of the processing configuration (processing modules) of the server device 20 according to the first embodiment. Referring to FIG. 3, the server device 20 includes a communication control unit 201, a user information registration unit 202, a first verification unit 203, and a storage unit 204.

[0039] The communication control unit 201 is a means for controlling communication with other devices. Specifically, the communication control unit 201 receives data (packets) from the gate device 10. Also, the communication control unit 201 transmits data to the gate device 10.

[0040] The user information registration unit 202 is a means for acquiring gate user information and registering the acquired gate user information in the gate user database constructed in the storage unit 204. Any method can be used to acquire the gate user information.

[0041] For example, at the passport issuance window, the responsible staff may register the gate user information in the server device 20. Specifically, the responsible staff operates the scanner to read the page with the face photo and MRZ of the passport. The responsible staff operates the terminal (computer installed at the issuance window) and transmits the read data (image data) to the server device 20. Alternatively, the read data may be input into the server device 20 via an external storage device such as a USB (Universal Serial Bus) memory.

[0042] During the check-in procedure at the airport, the above data (image data including the face photo and MRZ) may be input into the server device 20. Specifically, when the airline staff checks the user's passport, the page with the face photo and MRZ is read using a scanner. The airline staff may transmit the read data from the terminal to the server device 20.

[0043] Alternatively, the user himself / herself may read the page with the face photo and MRZ of the passport using a so-called automatic check-in machine. In this case, the read data is transmitted from the automatic check-in machine to the server device 20.

[0044] The user may take a photo of the page with the face photo and MRZ of the passport and acquire image data including the face photo and MRZ. Specifically, the user uses a smartphone or the like to take a photo of the page including the face photo and MRZ of the passport. Then, the taken image data is transmitted from the smartphone or the like to the server device 20.

[0045] Alternatively, the image data including the face photo and the MRZ may be obtained from a database storing the history of users who have traveled abroad. Specifically, when the face photo and the MRZ have been obtained at a manned immigration booth in the past and registered in the database, the image data may be transmitted from the database to the server device 20.

[0046] The user information registration unit 202 obtains the image data including the face photo and the MRZ described in the user's passport by any of the methods described above or other methods.

[0047] The user information registration unit 202 extracts feature points from the face image included in the acquired image data. Since existing techniques can be used for the extraction process of feature points, detailed description thereof is omitted. For example, the user information registration unit 202 extracts eyes, nose, mouth, etc. from the face image as feature points. Thereafter, the user information registration unit 202 calculates the position of each feature point and the distance between each pair of feature points as feature amounts, and generates a feature vector (vector information characterizing the face image) composed of a plurality of feature amounts.

[0048] The user information registration unit 202 extracts the MRZ information from the image data including the MRZ information. Specifically, the user information registration unit 201 extracts the MRZ information from the image data using optical character recognition (OCR) technology.

[0049] The user information registration unit 202 associates the generated feature vector with the extracted MRZ information and registers it in the gate user database.

[0050] FIG. 4 is a diagram showing an example of the gate user database. As shown in FIG. 4, the feature vector generated from the face image is registered as biometric information. Also, the MRZ information corresponding to each biometric information (feature vector) is registered in the gate user database.

[0051] The first matching unit 203 is a means for processing the matching request transmitted by the gate device 10. Specifically, the first matching unit 203 sets the biometric information (feature vector) included in the matching request as the matching target, and performs a matching process with the biometric information registered in the gate user database.

[0052] More specifically, the first matching unit 203 sets the feature vector extracted from the matching request as the matching target, and executes a one-to-N (N is a positive integer, the same hereinafter) matching with a plurality of feature vectors registered in the gate user database.

[0053] The first matching unit 203 calculates the similarity between the feature vector of the matching target and each of the plurality of feature vectors on the registration side. For the similarity, the chi-square distance, the Euclidean distance, etc. can be used. Note that the greater the distance, the lower the similarity, and the closer the distance, the higher the similarity.

[0054] The first matching unit 203 identifies the feature vector that has a similarity with the feature vector of the matching target equal to or greater than a predetermined value and has the highest similarity among the plurality of feature vectors registered in the gate user database.

[0055] The first matching unit 203 reads out the MRZ information corresponding to the feature vector (biometric information) obtained as a result of the one-to-N matching from the gate user database. The first matching unit 203 transmits the read MRZ information to the gate device 10 that is the transmission source of the matching request (responds to the matching request).

[0056] For example, in the example of FIG. 4, if the feature vector FV acquired from the gate device 10 is most similar to the feature vector FV1 stored in the gate user database and the similarity is equal to or greater than a predetermined value, the corresponding MRZ01 is transmitted to the gate device 10.

[0057] If, as a result of the above one-to-N matching, biometric information that matches (substantially matches or is similar to) the biometric information included in the matching request is not registered in the gate user database, the first matching unit 203 notifies the gate device 10 to that effect. For example, the first matching unit 203 sets "None" in the feature vector and responds to the gate device 10.

[0058] Alternatively, the first matching unit 203 may notify the gate device 10 that the biometric information included in the matching request does not exist in the gate user database by not responding to the gate device 10 at all. In this case, the gate device 10 that sent the matching request recognizes that the biometric information included in the matching request does not exist in the gate user database because it cannot receive a response from the server device 20 within a predetermined period.

[0059] The storage unit 204 stores various types of information necessary for the operation of the server device 20. Also, as described above, a gate user database is constructed in the storage unit 204.

[0060] FIG. 5 is a diagram showing an example of the hardware configuration of the server device 20 according to the first embodiment. The server device 20 can be configured by an information processing device (so-called computer) and includes the configuration illustrated in FIG. 5. For example, the server device 20 includes a processor 211, a memory 212, an input / output interface 213, a communication interface 214, and the like. The components such as the processor 211 are connected by an internal bus or the like and are configured to be able to communicate with each other.

[0061] However, the configuration shown in FIG. 5 is not intended to limit the hardware configuration of the server device 20. The server device 20 may include hardware not shown, or may not include the input / output interface 213 if necessary. Also, the number of processors 211 and the like included in the server device 20 is not intended to be limited to the example shown in FIG. 5. For example, a plurality of processors 211 may be included in the server device 20.

[0062] The processor 211 is a programmable device such as a CPU (Central Processing Unit), MPU (Micro Processing Unit), DSP (Digital Signal Processor), etc. Alternatively, the processor 211 may be a device such as an FPGA (Field Programmable Gate Array), ASIC (Application Specific Integrated Circuit), etc. The processor 211 executes various programs including an operating system (OS; Operating System).

[0063] The memory 212 is a RAM (Random Access Memory), ROM (Read Only Memory), HDD (Hard Disk Drive), SSD (Solid State Drive), etc. The memory 212 stores an OS program, application programs, and various data.

[0064] The input / output interface 213 is an interface for a display device and an input device (not shown). The display device is, for example, a liquid crystal display, etc. The input device is a device that receives user operations such as a keyboard and a mouse, etc.

[0065] The communication interface 214 is a circuit, module, etc. that communicates with other devices. For example, the communication interface 214 includes a NIC (Network Interface Card), etc.

[0066] The functions of the server device 20 are realized by various processing modules. The processing modules are realized, for example, by the processor 211 executing a program stored in the memory 212. Further, the program can be recorded on a computer-readable storage medium. The storage medium can be a non-transitory one such as a semiconductor memory, a hard disk, a magnetic recording medium, an optical recording medium, etc. That is, the present invention can also be embodied as a computer program product. Further, the above program can be downloaded via a network or updated using a storage medium storing the program. Furthermore, the above processing module may be realized by a semiconductor chip.

[0067] [Gate device] Next, the gate device 10 according to the first embodiment will be described.

[0068] FIG. 6 is a diagram showing an example of the hardware configuration of the gate device 10 according to the first embodiment. Referring to FIG. 6, the gate device 10 includes a processor 311, a memory 312, an input / output device 313, a communication interface 314, a camera device 315, a reader 316, and a gate 317.

[0069] Note that, regarding the processor 311, the memory 312, and the communication interface 314, since they can be the same as the corresponding elements of the server device 20 described with reference to FIG. 5, detailed description thereof will be omitted.

[0070] The input / output device 313 is a device for inputting information to the gate device 10 (for example, a touch panel) or a device for outputting information (for example, a liquid crystal monitor).

[0071] The camera device 315 is, for example, a digital camera installed so as to be able to photograph in front (forward) of the gate device 10. The camera device 315 can be installed at any location. For example, the camera device 315 may be installed on the main body of the gate device 10, or may be installed at a location away from the gate device 10. The camera device 10 may be installed at any location as long as it can photograph a user approaching the gate device 10 (particularly, the user's face).

[0072] The reader 316 is a device that reads information from a passport. The reader 316 has a function of accessing an IC chip mounted on the passport and a function of scanning the page of the placed passport. That is, the reader 316 has a function as a card reader that exchanges information (data) with the IC chip of the passport in a non-contact state, and a function as a passport reader (scanner) that acquires an image from the passport. The reader 316 can be installed at any location. However, the reader 316 is preferably installed at a location where a user can easily touch the passport to the device. In the present disclosure, the reader 316 will be described as having a function as a card reader and a function as a passport reader, but it goes without saying that these two functions may be realized by different devices.

[0073] When a user passes through the immigration inspection, the gate 317 shifts from a closed state during standby that blocks the user's passage to an open state that permits the user's passage. The type of the gate 317 is not particularly limited, and examples include a flapper gate in which flappers provided on one or both sides of a passage open and close, a turnstile gate in which three bars rotate, and the like.

[0074] FIG. 7 is a diagram showing an example of a processing configuration (processing module) of the gate device 10 according to the first embodiment. Referring to FIG. 7, the gate device 10 includes a communication control unit 301, a biometric information acquisition unit 302, a collation request unit 303, a passport possession determination unit 304, a gate control unit 305, and a storage unit 306.

[0075] The communication control unit 301 is a means for controlling communication with other devices, similar to the communication control unit 201 of the server device 20.

[0076] The biological information acquisition unit 302 is a means for acquiring the biological information of a user who intends to pass through the gate device 10. For example, the biological information acquisition unit 302 controls the camera device 315 to acquire a face image of a person walking towards the own device (gate device 10). For example, when the biological information acquisition unit 302 detects the face of the user in the image taken constantly or periodically, it takes a picture of the face of the user and acquires the face image.

[0077] When the size of the face region included in the taken image is equal to or greater than a predetermined value, the biological information acquisition unit 302 may extract the face region from the image. In this case, by appropriately adjusting the predetermined value (threshold value), a face image of a user located at a predetermined distance from the gate device 10 can be acquired. That is, it is possible to prevent a user located far from the gate device 10 from being photographed and inappropriate biological information for face authentication (1-to-N matching by the server device 20) from being transmitted to the server device 20.

[0078] Alternatively, the biological information acquisition unit 302 may use a distance sensor or the like to measure the distance between the gate device 10 and the user, and acquire a face image of the user present at a predetermined position.

[0079] The biological information acquisition unit 302 delivers the acquired face image to the collation request unit 303.

[0080] The collation request unit 303 is a means for requesting the server device 20 to collate whether the biological information of the person corresponding to the acquired face image is registered in the gate user database. Specifically, the collation request unit 303 calculates feature amounts from the acquired face image, and generates a feature vector composed of the plurality of feature amounts (generates a feature vector corresponding to the biological information registered in the server device 20).

[0081] The matching request unit 303 generates a matching request including the generated feature vector (biometric information) and transmits it to the server device 20.

[0082] For example, the matching request unit 303 generates a matching request including the identifier of its own device (hereinafter referred to as the gate identifier), the feature vector, etc. (see FIG. 8). Note that the MAC (Media Access Control) address or IP (Internet Protocol) address of the gate device 10 can be used as the gate identifier.

[0083] The matching request unit 303 receives a response from the server device 20 for the matching request. The matching request unit 303 passes the response from the server device 20 (MRZ information corresponding to the feature vector specified by the one-to-N matching) to the passport possession determination unit 304.

[0084] The passport possession determination unit 304 is a means for determining whether a user attempting to pass through the gate device 10 holds a valid passport. Specifically, the passport possession determination unit 304 attempts to read information from the IC chip of the passport held in front of the reader 316 using the MRZ information acquired from the matching request unit 303.

[0085] Here, as described in "Security Measures for IC Passports" in Reference 1 below, the information stored in the IC chip of the passport is encrypted (converted) using the MRZ information described in the same passport as a password. <Reference 1> https: / / www.mofa.go.jp / mofaj / toko / passport / ic_faq.html#11

[0086] When the passport possession determination unit 304 can read information from the IC chip using the MRZ information acquired from the server device 20 (when the decryption of the information is successful), it determines that the user attempting to pass through the gate device 10 holds a valid passport.

[0087] On the other hand, when the passport possession determination unit 304 is unable to read information from the IC chip using the MRZ information obtained from the server device 20, it determines that the user attempting to pass through the gate device 10 does not possess a valid passport.

[0088] In this way, if the passport possession determination unit 304 succeeds in reading information from the IC chip using the MRZ information (if the cipher can be decrypted), it determines that the user possesses a valid passport. Therefore, the passport possession determination unit 304 may or may not confirm the content of the information read from the IC chip.

[0089] When the passport possession determination unit 304 determines that the user attempting to pass through the gate device 10 possesses a valid passport, it instructs the gate control unit 305 to "open the gate".

[0090] When the passport possession determination unit 304 determines that the user attempting to pass through the gate device 10 does not possess a valid passport, it does not perform any special operation. That is, when it is determined that the user attempting to pass through the gate device 10 does not possess a valid passport, the gate 317 will not open.

[0091] The gate control unit 305 is a means for controlling the gate 317 provided in the gate device 10. Specifically, the gate control unit 305 controls the opening and closing of the gate 317 in accordance with an instruction from the passport possession determination unit 304. After a user possessing a valid passport whose passage has been permitted passes through the gate 317 using a distance sensor or the like, the gate control unit 305 closes the gate 317.

[0092] [Operation of the Immigration Inspection System] Next, the operation of the immigration inspection system according to the first embodiment will be described.

[0093] FIG. 9 is a sequence diagram showing an example of the operation of the immigration system according to the first embodiment. Note that FIG. 9 is a sequence diagram showing an example of the system operation on the user's boarding date. Prior to the operation of FIG. 9, it is assumed that the "gate user information" of the user has been registered in the server device 20 in advance.

[0094] When the user approaches the self-device, the gate device 10 acquires biometric information from the user (step S01). For example, the gate device 10 acquires a face image of the user.

[0095] When the acquisition of the face image is successful, the gate device 10 transmits a collation request including the biometric information of the user to the server device 20 (step S02). Specifically, the gate device 10 calculates a feature vector from the face image and transmits a collation request including the calculated feature vector to the server device 20.

[0096] The server device 20 that has acquired the collation request extracts biometric information (feature vector) from the collation request and performs a one-to-N collation between the feature vector and the biometric information registered in the gate user database (step S03). The server device 20 searches for biometric information that is most similar to the biometric information acquired from the gate device 10 among the plurality of biometric information registered in the gate user database and whose similarity is equal to or greater than a predetermined value.

[0097] The server device 20 transmits a response including the MRZ information specified as a result of the one-to-N collation to the gate device 10 (the gate device 10 that transmitted the collation request) (step S04).

[0098] The gate device 10 reads information from the IC chip of the passport held in front of the reader 316 using the received MRZ information and determines the success or failure thereof (step S05). If the gate device 10 fails to read information from the IC chip (branch to No in step S05), no special processing is performed. In this case, the gate 317 of the gate device 10 remains closed.

[0099] When the gate device 10 successfully reads the information from the IC chip (step S05, Yes branch), it opens the gate 317 (step S06).

[0100] In this way, the gate device 10 acquires the biometric information of the user under review and transmits the biometric information of the user under review to the server device 20. The server device 20 searches for the gate user information and identifies the MRZ information corresponding to the received biometric information, and transmits the identified MRZ information to the gate device 10. When the gate device 10 successfully reads the information from the IC chip of the passport using the received MRZ information, it controls the gate so that the user under review can pass through.

[0101] Here, the gate device 10 opens the gate 317 only when the user who has previously registered the gate user information with the server device 20 presents his or her correct passport to the gate device 10. In other words, in the following cases, the gate 317 does not open and the immigration inspection by the gate device 10 does not end normally.

[0102] For example, even if a user who has not registered the gate user information with the server device 20 presents his or her passport to the gate device 10, the corresponding MRZ information cannot be obtained from the server device 20, so the gate 317 does not open. In this case, the gate device 10 may display to that effect (that the necessary information is not registered with the server device) and may also display a prompt to move to the manned immigration inspection area.

[0103] Even if the gate user information is registered in the server device 20, if the user tries to pass through without bringing the passport into contact with the reader 316 of the gate device 10, the gate 317 will not open. This is because the gate device 10 is a device that automatically conducts immigration inspection, and it is an important function to confirm that the user has a valid passport. That is, even if the gate user information has been previously registered in the server device 20, the gate 317 will not open unless it can be confirmed that the user registered with that information has a passport. In this case, the gate device 10 may provide a display, voice guidance, etc. to prompt the user to bring the correct passport (their own passport) into contact with the reader 316.

[0104] Alternatively, it is assumed that the gate device 10 may not be able to read the MRZ information because the passport is stored in a case or the like even though the user has brought the passport into contact with the reader 316. In such a case, the gate device 10 may display a message prompting the user to take the passport out of the case or the like and bring it into contact with the reader 316, or display a message prompting the user to open the passport and bring it into contact with the reader 316.

[0105] Alternatively, the gate 317 will not open even if the user presents a passport of someone else instead of their own passport to the gate device 10. For example, even if the gate user information of a parent and child is registered in the server device 20 respectively, if the parent presents the child's passport to the gate device 10, the gate 317 will not open. Also in this case, the gate device 10 may provide a display, voice guidance, etc. to prompt the user to bring the correct passport (their own passport) into contact with the reader 316.

[0106] As described above, in the immigration inspection system according to the first embodiment, biometric information of a user who wishes to use the gate device 10 is registered in advance in the server device 20. Then, when the user appears in front of the gate device 10 on the boarding date, the gate device 10 acquires the biometric information of the user and inquires whether the acquired biometric information is registered in the server device 20 (requests the server device 20 to perform one-to-N verification using the biometric information). As a result of the verification, when it is confirmed that the biometric information of the user is registered in the server device 20, the gate device 10 checks whether the passport presented by the user is truly the user's passport. Specifically, the gate device 10 checks whether it can read information from the IC chip of the passport using the MRZ information specified by the result of face authentication from the server device 20. As described above, in order to extract information from the IC chip, the MRZ information described in the same passport is required. Therefore, the fact that successful reading of information from the IC chip using the MRZ information indicates that the MRZ information obtained from the server device 20 matches the MRZ information of the passport presented by the user. Based on this match, the gate device 10 determines that the user in front of it has the correct passport and opens the gate (allows the user to pass through the immigration inspection). Thus, in the first embodiment, if information is registered in the database in advance, the user can complete the immigration inspection simply by contacting the gate device 10 without opening the passport. As a result, it is possible to realize a smooth immigration inspection that is highly convenient for the user.

[0107] [Second Embodiment] Subsequently, the second embodiment will be described in detail with reference to the drawings.

[0108] In the first embodiment, it is assumed that there is no contradiction (discrepancy) between the biometric information and the MRZ information of the gate user information registered in the server device 20. When the gate user information is registered by a public agency staff member, it is unlikely that the above contradiction will occur, but when the user registers the gate user information in the server device 20, there is a slight possibility that the above contradiction will occur.

[0109] If the above contradiction exists, correct immigration inspection cannot be performed and problems will occur. In the second embodiment, a case where more reliable immigration inspection is realized by performing collation processing also in the gate device 10 will be described.

[0110] In the second embodiment, since the schematic configuration of the immigration system and the processing configuration of the server device 20 can be the same as those in the first embodiment, descriptions corresponding to FIG. 2, FIG. 3, etc. are omitted. Hereinafter, the description will focus on the differences between the first and second embodiments.

[0111] FIG. 10 is a diagram showing an example of the processing configuration (processing module) of the gate device 10 according to the second embodiment. Referring to FIG. 10, a second collation unit 307 is added to the configuration shown in FIG. 7.

[0112] The second collation unit 307 is a means for performing collation (one-to-one collation) as to whether the biometric information of the user matches the biometric information read from the IC chip of the passport that the user has brought into contact with the reader 316.

[0113] The biometric information acquisition unit 302 stores the acquired biometric information (for example, the face image of the user photographed using the camera device 315) in the storage unit 306.

[0114] When the passport possession determination unit 304 succeeds in reading information from the IC chip using the MRZ information acquired from the server device 20, it delivers the face image among the read information to the second collation unit 307.

[0115] The second matching unit 307 performs matching (one-to-one matching) between the face image acquired from the passport possession determination unit 304 and the face image stored in the storage unit 306. Specifically, the second matching unit 307 calculates feature vectors from each of the two images. Then, the second matching unit 307 calculates the similarity (e.g., Euclidean distance) between the two images, and based on the result of threshold processing for the calculated similarity, determines whether the two images are face images of the same person. For example, if the similarity is greater than a predetermined value (if the distance is shorter than a predetermined value), the second matching unit 307 determines that the two face images are by the same person.

[0116] When the second matching unit 307 succeeds in one-to-one matching (when the face image of the user in front of the gate and the face image read from the IC chip of the presented passport match), it instructs the gate control unit 305 to open the gate.

[0117] In this way, when the matching between the biometric information acquired from the user and the biometric information read from the IC chip presented by the user succeeds, the gate device 10 opens the gate 317 so that the user can pass through. That is, the gate device 10 controls the gate 317 so that the user can pass through when the distance between the feature vectors obtained from each of the above two biometric informations is shorter than a predetermined distance and the two biometric informations can be determined to be substantially the same.

[0118] As described above, in the second embodiment, a one-to-one comparison is performed between the face image of the user obtained from the camera device 315 attached to the gate device 10 and the face image read from the IC chip of the passport presented by the user. When the one-to-one comparison results in successful authentication of the user, the gate device 10 opens the gate 317. That is, even in a case where there is a contradiction in the gate user information registered in the server device 20 and which was a problem in the first embodiment, in the second embodiment, by performing the final user authentication, it is possible to prevent a user who should not pass through the gate device 10 from passing through the gate device 10. In the second embodiment, by performing a one-to-one comparison at the gate device 10 after the one-to-N comparison in the server device 20, it is ensured that the user attempting to pass through the gate device 10 has the correct passport (their own passport).

[0119] [Modification Example] Note that the configuration, operation, etc. of the immigration inspection system described in the above embodiment are examples and are not intended to limit the system configuration.

[0120] For example, all or part of the functions of the server device 20 may be realized by the gate device 10. Alternatively, the gate user database provided in the server device 20 may be constructed in another database server. The immigration inspection system may include a storage means (storage unit 204) for storing gate user information, a comparison means (first comparison unit 203) for performing a one-to-N comparison using the gate user information, a determination means (passport possession determination unit 304) for determining whether the user has a passport, etc.

[0121] In the above embodiment, the case where the feature vectors calculated from the face images are transmitted and received between the gate device 10 and the server device 20 has been described. However, the face image may be transmitted from the gate device 10 to the server device 20. In this case, a collation request including the face image is transmitted from the gate device 10 to the server device 20, and the server device 20 may calculate the feature vectors from the received face images and perform 1-to-N collation. Alternatively, face images instead of feature vectors may be registered in the user information database of the server device 20, and feature amounts may be calculated each time collation is performed.

[0122] In the above embodiment, it is assumed that the gate devices 10 are installed separately from each other, and it is not considered that a user heading for a certain gate device 10 presents a passport to a gate device 10 different from the said gate device 10. However, as shown in FIG. 11, an installation form is also conceivable in which users line up and, when a vacant gate device 10 becomes available after the inspection is completed, they walk towards the said vacant gate device 10. In this case, each gate device 10 cannot know whether or not the said user will finally present a passport to its own device even if it takes a face image by photographing the lined-up users. Therefore, the server device 20 may transmit a response (response including MRZ information) to the response request not only to the source of the said response request but also to other gate devices 10. For example, in FIG. 11, consider the case where the gate device 10-2 photographs the lined-up users and transmits a collation request including the biometric information of the said users. In this case, the server device 20 transmits the MRZ information obtained as a result of the 1-to-N collation not only to the gate device 10-2 which is the source of the collation request but also to the gate devices 10-1 and 10-3. As a result, as shown in FIG. 11, even when the user heads for the gate device 10-1 instead of the gate device 10-2, the immigration inspection (success or failure of information reading from the IC chip based on the MRZ information) regarding the said user can be executed. This is because the gate device 10-1 has the MRZ information corresponding to the said user's passport.

[0123] In the above-described embodiment, it is assumed that one face region is included in one image. However, depending on the situation at the inspection site, a single image may contain multiple face regions. In this case, the server device 10 may extract the face region closest to its own device and transmit the biometric information to the server device 20. For example, the server device 10 may calculate the area of each face region and extract the face region with the largest area. Alternatively, a depth camera or the like capable of measuring the distance in the depth direction may be employed in the camera device 10 to measure the distance from the camera device 10 and extract the face image of the person who is closer.

[0124] Further, the present disclosure realizes smooth inspection by allowing the user to complete the immigration inspection simply by bringing the passport into contact with the card reader 316 without opening the passport, but does not exclude the user from opening the passport. For example, when predetermined conditions are satisfied, the user may be asked to open the passport and inspection using the passport may be performed. For example, when the collation result by the server device 20 is not so high (when the similarity is lower than a predetermined threshold), in addition to the MRZ information, the server device 20 notifies the gate device 10 of the above-mentioned fact (the collation result is poor). The gate device 10 that has received the notification may instruct the user to open the passport and place the page on which the face photo and MRZ are described on the reader 316. The gate device 10 acquires biometric information (face image) from the user (the user in front) and performs one-to-one collation using the biometric information and the face image obtained from the IC chip of the passport. If it is determined as a result of the collation that the user is holding the correct passport, the gate device 10 may open the gate 317.

[0125] Alternatively, when the gate device 10 is unable to read information from the IC chip of the passport using the MRZ information received from the server device 20, the gate device 10 may prompt the user under inspection to open the passport and place it on the reader 316. Also in this case, if the gate device 10 determines as a result of the collation that the user is holding the correct passport, the gate device 10 opens the gate 317.

[0126] The gate device 10 may change its operation according to the attributes of the user. For example, in immigration inspection, for those with Japanese nationality, fingerprint collection is not required, but for those without Japanese nationality, fingerprint collection is necessary. Therefore, the gate device 10 may determine the nationality (Japanese nationality, non-Japanese nationality) of the user based on the MRZ information obtained from the server device 20, and change the control including the gate opening and closing operation according to the result. For example, regarding the immigration inspection of foreigners, the gate 317 may be opened after the fingerprint collection and the inspection regarding the collected fingerprint are successfully completed.

[0127] In the above embodiment, the case where the gate device 10 is installed at one airport (departure airport or arrival airport) has been described. However, the gate device 10 may be installed at both the departure airport and the arrival airport (see Fig. 12). For users whose gate user information has already been registered in the server device 20, re-registration of the gate user information is not required, and they can receive smooth immigration inspection by the gate device 10 according to the present disclosure.

[0128] Alternatively, as shown in Fig. 12, when the gate device 10 of the present disclosure is installed at both the departure airport and the arrival airport, the gate user information registered in the server device 10 may be deleted for each flight of the user. This is because the MRZ information including biometric information and name registered in the server device 20 belongs to personal information, and it is not desirable to retain such personal information for a long time. In this case, when the server device 20 receives a notification from the arrival-side gate device 10 (gate device 10-5 in the example of Fig. 12) that the immigration inspection of the user has been successfully completed, the server device 20 deletes the gate user information of the user. Alternatively, when the departure-side gate device 10 (gate device 10-4 in the example of Fig. 12) successfully completes the departure inspection of the user, it may notify the arrival-side gate device 10-5 of this fact. In this case, after the immigration inspection of the user is completed, the gate device 10-5 may request the server device 20 to delete the corresponding gate user information.

[0129] In the above-described embodiment, the operation of the gate device 10 and the server device 20 has been mainly described using the "face" as biometric information. However, the biometric information that can be used in the present disclosure is not limited to the "face". Other biometric information such as iris can be used.

[0130] The form of data transmission and reception between the gate device 10 and the server device 20 is not particularly limited, but the data transmitted and received between these devices may be encrypted. Since face images and feature amounts calculated from the face images are personal information, it is desirable that encrypted data be transmitted and received in order to appropriately protect the personal information.

[0131] In the above-described embodiment, the case of acquiring information using MRZ information from the IC chip of the passport has been described. However, the method disclosed in the present application is also applicable to other methods. That is, when reading information from an IC chip mounted on a medium such as a card similar to a passport, information related to a password or a key corresponding to the MRZ information may be used.

[0132] In the flowcharts (flowcharts, sequence diagrams) used in the above description, a plurality of steps (processes) are described in order. However, the execution order of the steps executed in the embodiment is not limited to the described order. In the embodiment, for example, the order of the illustrated steps can be changed within a range that does not substantially affect the content, such as executing each process in parallel.

[0133] The above-described embodiment has been described in detail to facilitate understanding of the present disclosure, and it is not intended that all the configurations described above are necessary. Also, when a plurality of embodiments are described, each embodiment may be used alone or in combination. For example, it is also possible to replace a part of the configuration of an embodiment with the configuration of another embodiment, or to add the configuration of another embodiment to the configuration of an embodiment. Furthermore, it is possible to add, delete, or replace other configurations for a part of the configuration of an embodiment.

[0134] From the above description, the industrial applicability of the present invention is clear. The present invention is suitably applicable to, for example, an immigration inspection system at an airport.
