Description

  Embodiments described herein relate generally to a ticket gate system, an issuing machine, a ticket gate machine, and a ticket gate method.

  Ticket gate processing in transportation such as railway is automated by a ticket gate system. The ticket gate system includes various station service devices such as an automatic ticket gate installed at each station and an automatic ticket vending machine that issues a pass ticket. Various station service devices are communicably connected via a network (station network). Further, a central management apparatus that controls all stations is connected to this network (inter-station network).

  In metropolitan areas, a ticket gate system that can handle IC pass tickets has been introduced. For example, an IC card reader provided in an automatic ticket gate that can handle an IC pass ticket reads the pass ticket information from the IC pass ticket, and an automatic ticket gate that can handle an IC pass ticket reads the passed ticket information. Based on this, it is determined whether or not traffic is permitted.

  Further, the automatic ticket gate capable of handling an IC pass ticket is configured to be compatible with a magnetic pass ticket in addition to an IC pass ticket. Therefore, an automatic ticket gate capable of handling an IC pass ticket includes a magnetic ticket transport mechanism for receiving, transporting, and returning a magnetic pass ticket. The cost burden of the railway operator for constructing and maintaining a ticket gate system that can handle both the IC ticket and the magnetic ticket as described above is heavy.

  Therefore, the introduction of a two-dimensional code ticket that replaces the magnetic ticket has been proposed. In the two-dimensional code pass ticket, pass ticket information by an optically readable two-dimensional code (for example, QR code (registered trademark)) is recorded. An automatic ticket gate capable of handling a two-dimensional code pass ticket may be provided with a code reader for optically reading a two-dimensional code. The code reader optically reads the two-dimensional code printed on the two-dimensional code pass ticket, and the automatic ticket gate that can handle the two-dimensional code pass ticket can pass based on the pass ticket information indicated by the read two-dimensional code. Determine.

  Automatic ticket gates that can handle two-dimensional code pass tickets do not require the above-mentioned magnetic ticket transport mechanism, etc., so they can be configured at lower costs than automatic ticket gates that can handle magnetic pass tickets. Maintenance costs are also low. On the other hand, since 2D codes are copied relatively easily, there is a need for a mechanism to prevent unauthorized traffic due to unauthorized 2D code tickets generated by unauthorized copying, and there are various mechanisms for preventing unauthorized traffic. Proposed.

  For example, the ticket identification information recorded on a two-dimensional code pass ticket that has been normally issued is unique information. However, the ticket identification information recorded in the illegal two-dimensional code pass ticket created by illegal copying is not unique information, and is the same as the ticket identification information recorded in the copy source two-dimensional code pass ticket. Identification information.

  Therefore, the ticket identification information recorded on the two-dimensional code pass ticket that has been properly issued is transmitted to each automatic ticket checker at each station, the identification information read from each two-dimensional code pass ticket is checked, and an illegal two-dimensional A mechanism to prevent unauthorized boarding with code pass tickets is conceivable.

JP 2006-59249 A

  However, in the above-described ticket gate system, ticket identification information cannot be distributed to the automatic ticket checker when the network in the station or the network between the stations becomes unable to communicate due to a line failure or the like, which may cause trouble for the user. is there.

  In addition, since it is necessary to distribute the voucher information recorded in the two-dimensional code pass ticket with a large number of issued tickets to the automatic ticket gates at each station, the load on the network including the host server becomes very large. Under such circumstances, a mechanism for efficiently preventing illegal boarding by an illegal two-dimensional code pass ticket is desired.

  An object of the present invention is to provide a ticket gate system, an issuing machine, a ticket gate machine, and a ticket gate method excellent in fraud prevention.

  The ticket gate system according to the embodiment includes an issuing machine and a ticket gate. The issuing machine acquires first face image data, encrypts pass ticket information based on the first face image data, and issues encrypted pass ticket information. The ticket gate acquires second face image data, optically reads the encrypted ticket information, decrypts the encrypted ticket information based on the second face image data, and decrypts the ticket. A ticket gate process is executed based on the information.

  FIG. 5 is a flowchart for issuing the pass ticket information (passage ticket in which the pass ticket information is recorded so as to be optically readable) in the ticket gate system according to the embodiment. Hereinafter, with reference to FIG. 1 and FIG. 5, a process for issuing the pass ticket information (passage ticket in which the pass ticket information is recorded so as to be optically readable) in the ticket gate system according to the embodiment will be described.

  In the present embodiment, an example in which a ticket gate system user obtains pass ticket information using the mobile phone 3, and a ticket gate system user records the pass ticket information using an automatic ticket vending machine 8 in an optically readable manner. An example of obtaining a pass ticket (sheet 8a), and an example in which a ticket gate system user obtains a pass ticket (sheet 6a) on which pass ticket information is recorded in an optically readable manner using the printer 6 will be described.

  When the user operates the mobile phone 3 owned by the user to call the central management device 1 via the communication network L1 and the mobile phone 3 and the central management device 1 are connected (S100, YES), the mobile phone A guide screen for purchasing a pass ticket is displayed on the display screen 3a of the telephone 3, and the user performs a purchase operation according to the guide. Thereby, the cellular phone 3 transmits the pass ticket purchase information to the central management device 1 (S101, YES).

  The pass ticket purchase information includes traffic condition information and first face image data. The traffic condition information includes information such as a traffic section. The first face image data is face image data of a pass ticket user (pass ticket purchaser) stored in the storage unit 82. Note that the face image data stored in the storage unit 82 is, for example, face image data captured by the camera Ca1 of the mobile phone 3.

  The communication unit 103 of the central management device 1 receives the pass ticket purchase information, and the checkout processing unit 105 of the central management device 1 confirms that the balance of the account of the user's financial institution is greater than or equal to the remaining amount at which the pass ticket can be purchased. Confirm (S102, YES).

  Furthermore, the issuing unit 106 of the central management device 1 generates the pass ticket information based on the pass condition information included in the pass ticket purchase information, and the pass ticket based on the first face image data included in the pass ticket purchase information. The information is encrypted, and a two-dimensional code including the encrypted ticket information and the non-encrypted ticket ID is issued. More specifically, the issuing unit 106 extracts a first face feature amount (first feature data) from the first face image data, and encrypts the pass ticket information using the first face feature amount as an encryption key. Then, the encrypted ticket information is generated and a two-dimensional code including the encrypted ticket information and the non-encrypted ticket ID is issued. That is, the communication unit 103 of the central management device 1 transmits a two-dimensional code including the encrypted pass ticket information and the non-encrypted pass ticket ID to the mobile phone 3 (S103). The pass ticket information includes a valid section and a valid period of the pass ticket. The pass ticket ID is identification information for uniquely specifying the pass ticket information.

  The mobile phone 3 receives the two-dimensional code including the encrypted ticket information and the non-encrypted ticket ID, and stores the received two-dimensional code. The display screen 3a of the mobile phone 3 can display the stored two-dimensional code. That is, the display screen 3a displays the two-dimensional code C1 including the encrypted pass ticket information and the non-encrypted pass ticket ID.

  On the other hand, the settlement processing unit 105 of the central management device 1 determines that the balance of the account of the user's financial institution is less than the amount by which the pass ticket information can be purchased (S102, NO), communication of the central management device 1 The unit 103 notifies the mobile phone 3 that the pass ticket information cannot be purchased. Correspondingly, the display screen 3a of the mobile phone 3 displays a guidance that "the ticket information cannot be purchased" (S104).

  That is, the user is operated so as to be able to purchase a pass ticket using the mobile phone 3 when an account withdrawal contract is made with the railway company in advance. In this case, payment of the purchase price for the pass ticket was made by debiting the account, but it is of course not limited to debiting the account, and it goes without saying that other payment methods such as post-payment and payment by credit card may be adopted. Yes.

  Further, using the PC 5 and the printer 6, the pass ticket information can be acquired in the same manner as described above. That is, the PC 5 transmits the pass ticket purchase information to the central management device 1. The pass ticket purchase information includes traffic condition information and first face image data. The traffic condition information includes information such as a traffic section. The first face image data is, for example, face image data photographed by a camera Ca2 connected to the PC 5. The communication unit 103 of the central management device 1 receives the pass ticket purchase information, and as described above, the communication unit 103 of the central management device 1 sends the encrypted pass ticket information and the non-encrypted pass ticket ID to the PC 5. A two-dimensional code including is transmitted.

  The PC 5 receives the two-dimensional code including the encrypted ticket information and the non-encrypted ticket ID, and stores the received two-dimensional code. The printer 6 can print (record) the two-dimensional code stored in the PC 5 on the paper 6a. That is, the printer 6 can issue a pass ticket on which the two-dimensional code is recorded (paper 6a on which the two-dimensional code C2 is recorded).

  In addition, the pass ticket information can be acquired using the automatic ticket vending machine 8 as described above. On the display screen of the operation input unit 84 of the automatic ticket vending machine 8, a guidance screen for purchasing a pass ticket is displayed, and the user performs a purchase operation via the operation input unit 84 according to the guidance. At this time, the camera Ca3 captures the pass ticket purchaser and acquires the first face image data. As a result, the operation input unit 84 of the automatic ticket vending machine 8 transmits the pass ticket purchase information to the issuing unit 86. The pass ticket purchase information includes traffic condition information and first face image data. The traffic condition information includes information such as a traffic section.

  The issuing unit 86 receives the pass ticket purchase information, the checkout processing unit 85 confirms that the amount of money to be inserted is equal to or greater than the amount that can be used to purchase the pass ticket, and the issue unit 86 receives the pass included in the pass ticket purchase information. Two-dimensional including pass ticket information generated based on condition information, encrypted pass ticket information based on first face image data included in pass ticket purchase information, and including encrypted pass ticket information and non-encrypted pass ticket ID Issue a toll ticket with a code. More specifically, the issuing unit 86 extracts a first face feature quantity (first feature data) from the first face image data, and encrypts the pass ticket information using the first face feature quantity as an encryption key. Then, the encrypted ticket information is generated, and a ticket in which the two-dimensional code including the encrypted ticket information and the non-encrypted ticket ID is recorded is issued. That is, the issuing port 87 can issue a pass ticket on which a two-dimensional code including encrypted pass ticket information and a non-encrypted pass ticket ID is recorded (paper 8a on which the two-dimensional code C3 is recorded).

  FIG. 6 is a flowchart showing a ticket gate process when entering the ticket gate system according to the embodiment. Hereinafter, with reference to FIG. 1 and FIG. 6, the ticket gate process at the time of entrance by the automatic ticket gate G of the ticket gate system according to the embodiment will be described.

  A user of the ticket gate system operates the mobile phone 3 to display the two-dimensional code C1 on the display screen 3a of the mobile phone 3. The camera Ca4 of the automatic ticket gate G captures the passerby and acquires the second face image data. When the display screen 3a is trapped by the optical reading unit 14 of the automatic ticket gate G (S200, YES), the optical reading unit 14 reads the two-dimensional code C1 displayed on the display screen 3a, and the CPU 22 The non-encrypted ticket ID included in the dimension code C1 is recognized, and the encrypted ticket information included in the two-dimensional code C1 is decrypted based on the second face image data acquired by the camera Ca4.

  For example, if the CPU 22 matches the passed ticket ID (entry ticket ID) stored in the memory 21 and the non-encrypted ticket ID included in the two-dimensional code C1, the user's You may make it determine with admission impossible.

  Alternatively, the user of the ticket gate system can also use the paper 6a on which the two-dimensional code C2 is recorded as a passing ticket. The camera Ca4 of the automatic ticket gate G captures the passerby and acquires the second face image data. Further, when the sheet 6a (passage ticket) on which the two-dimensional code C2 is recorded is put on the optical reading unit 14 of the automatic ticket gate G (S200, YES), the optical reading unit 14 is placed on the sheet 6a (passage ticket). The recorded two-dimensional code C2 is read, and the CPU 22 recognizes the non-encrypted pass ticket ID included in the two-dimensional code C2, and further, based on the second face image data acquired by the camera Ca4, the two-dimensional code C2 The encrypted passport information contained in is decrypted.

  For example, if the CPU 22 matches the passed ticket ID (entry ticket ID) stored in the memory 21 and the non-encrypted ticket ID included in the two-dimensional code C2, the user's You may make it determine with admission impossible.

  Alternatively, the user of the ticket gate system can also use the paper 8a on which the two-dimensional code C2 is recorded as a passing ticket. The camera Ca4 of the automatic ticket gate G captures the passerby and acquires the second face image data. Further, when the paper 8a (passage ticket) on which the two-dimensional code C2 is recorded is put on the optical reading unit 14 of the automatic ticket gate G (S200, YES), the optical reading unit 14 is placed on the paper 8a (passage ticket). The recorded two-dimensional code C3 is read, and the CPU 22 recognizes the non-encrypted pass ticket ID included in the two-dimensional code C3, and further, based on the second face image data acquired by the camera Ca4, the two-dimensional code C3. The encrypted passport information contained in is decrypted.

  For example, in the case where the CPU 22 matches the passed ticket ID (entry ticket ID) stored in the memory 21 and the non-encrypted ticket ID included in the two-dimensional code C3, the user's You may make it determine with admission impossible.

  If the first face image data used for encryption of the pass ticket information and the second face image data obtained by the camera Ca4 are face image data obtained from the same person, the first face image data obtained by the camera Ca4 is used. The encrypted passport information can be decrypted based on the two face image data. That is, since the first face feature amount of the first face image data obtained from the same person and the second face feature amount of the second face image data are substantially the same data, the first face feature amount When the pass ticket information is encrypted using the encryption key as the encryption key, the encrypted pass ticket information can be decrypted using the second face feature amount as the decryption key.

  However, if the first face image data used for encryption of the pass ticket information and the second face image data acquired by the camera Ca4 are face image data obtained from different persons, the camera Ca4 acquires the face image data. The encrypted passport information cannot be decrypted based on the second face image data. That is, the first face feature amount of the first face image data obtained from the regular pass ticket purchaser is different from the second face feature amount of the second face image data obtained from the unauthorized pass ticket acquirer. Therefore, when the pass ticket information is encrypted using the first face feature amount as an encryption key, the encrypted pass ticket information cannot be decrypted using the second face feature amount as a decryption key.

  The CPU 22 does not match the passed ticket ID (entry ticket ID) stored in the memory 21 with the non-encrypted ticket ID, and encrypts it based on the second face image data acquired by the camera Ca4. If the pass ticket information can be decrypted (S201, YES), it is determined whether or not the user can enter the ticket gate based on the decrypted pass ticket information (S202).

  Here, whether or not the user can enter the ticket gate is determined based on the valid period and valid period of the pass ticket included in the decrypted pass ticket information. That is, it is determined that the user can enter when the pass ticket is within the valid period and within the valid section. On the other hand, if the pass ticket is outside the valid period or outside the valid section, it is determined that the user cannot enter.

  When it is determined in S202 that the user can enter (S203, YES), the door D1 is controlled to be opened to allow the user to enter the station ticket gate (S204). After permitting the user to enter in S204, the memory 21 stores the read non-encrypted pass ticket ID as a passed pass ticket ID (entry pass ticket ID), and the communication control unit 28 is not encrypted. You may make it transmit to the central management apparatus 1 as a passage ticket ID (entranced passage ticket ID) which passed the chemical pass ticket ID (S205). The central management device 1 distributes the passed ticket ID to each automatic ticket checker at each station.

  On the other hand, when the CPU 22 cannot decrypt the encrypted passport information based on the second face image data acquired by the camera Ca4 (S201, YES), that is, in the case of a decryption error, or in the case of the admission impossible determination ( In S203, NO), the door D1 is controlled to be closed and the user is prohibited from entering (S206), and the speaker 13 informs the user that “the ticket information may be invalid”. Is issued (S207).

  FIG. 7 is a flowchart showing a ticket gate process when entering the ticket gate system according to the embodiment. Hereinafter, with reference to FIG. 1 and FIG. 7, the ticket gate process when the user who enters the station ticket gate by the automatic ticket gate G of the ticket gate system according to the embodiment enters outside the station ticket gate will be described.

  A user of the ticket gate system using the mobile phone 3 (two-dimensional code C1) at the time of entry operates the mobile phone 3 to display the two-dimensional code C1 on the display screen 3a of the mobile phone 3. The camera Ca4 of the automatic ticket gate G captures the passerby and acquires the second face image data. When the display screen 3a is trapped by the optical reading unit 14 of the automatic ticket gate G (S300, YES), the optical reading unit 14 reads the two-dimensional code C1 displayed on the display screen 3a, and the CPU 22 The non-encrypted ticket ID included in the dimension code C1 is recognized, and the encrypted ticket information included in the two-dimensional code C1 is decrypted based on the second face image data acquired by the camera Ca4.

  For example, in the case where the CPU 22 matches the passed ticket ID (passed ticket ID) stored in the memory 21 and the non-encrypted ticket ID included in the two-dimensional code C1, the user's You may make it determine that participation is impossible.

  Alternatively, the user of the ticket gate system using the paper 6a (two-dimensional code C2) at the time of entry uses the paper 6a on which the two-dimensional code C2 is recorded as an entrance ticket for entry. The camera Ca4 of the automatic ticket gate G captures the passerby and acquires the second face image data. When the sheet 6a (passage ticket) on which the two-dimensional code C2 is recorded is put on the optical reading unit 14 of the automatic ticket gate G (S300, YES), the optical reading unit 14 is placed on the sheet 6a (passage ticket). The recorded two-dimensional code C2 is read, and the CPU 22 recognizes the non-encrypted pass ticket ID included in the two-dimensional code C2, and further, based on the second face image data acquired by the camera Ca4, the two-dimensional code C2 The encrypted passport information contained in is decrypted.

  For example, if the CPU 22 matches the passed ticket ID (passed ticket ID) stored in the memory 21 and the non-encrypted ticket ID included in the two-dimensional code C2, the user's You may make it determine that participation is impossible.

  Alternatively, the user of the ticket gate system using the paper 8a (two-dimensional code C3) at the time of entry uses the paper 8a on which the two-dimensional code C3 is recorded as an entrance ticket. The camera Ca4 of the automatic ticket gate G captures the passerby and acquires the second face image data. Further, when the paper 8a (passage ticket) on which the two-dimensional code C2 is recorded is put on the optical reading unit 14 of the automatic ticket gate G (S300, YES), the optical reading unit 14 is placed on the paper 8a (passage ticket). The recorded two-dimensional code C3 is read, and the CPU 22 recognizes the non-encrypted pass ticket ID included in the two-dimensional code C3, and further, based on the second face image data acquired by the camera Ca4, the two-dimensional code C3. The encrypted passport information contained in is decrypted.

  For example, if the CPU 22 matches the passed ticket ID (passed ticket ID) stored in the memory 21 and the unencrypted ticket ID included in the two-dimensional code C3, the user's You may make it determine that participation is impossible.

  The CPU 22 encrypts based on the second face image data acquired by the camera Ca4 without matching the passed ticket ID (passed ticket ID) stored in the memory 21 and the non-encrypted ticket ID. If the conversion ticket information can be decrypted (S301, YES), it is determined based on the decryption ticket information whether it is possible for the user to enter the station ticket gate (S302).

  Here, whether or not the user can enter the ticket gate is determined based on the valid period and valid period of the pass ticket included in the decrypted pass ticket information. That is, it is determined that the user can enter when the pass ticket is within the valid period and within the valid section. On the other hand, if the pass ticket is outside the valid period or outside the valid section, it is determined that the user cannot enter.

  When it is determined in S302 that the user can enter (S303, YES), the door D1 is controlled to be opened, and the user is allowed to enter the station ticket gate (S304). After permitting the user to enter in S304, the memory 21 stores the read non-encrypted pass ticket ID as a passed pass ticket ID (entered pass ticket ID), and the communication control unit 28 performs non-encryption. You may make it transmit to the central management apparatus 1 as a passage ticket ID (passed ticket ID) which passed the chemical pass ticket ID (S305). The central management device 1 distributes the passed ticket ID to each automatic ticket checker at each station.

  On the other hand, when the CPU 22 cannot decrypt the encrypted passport information based on the second face image data acquired by the camera Ca4 (S301, YES), that is, in the case of a decryption error or a case where it is determined that participation is not possible ( In S303, NO), the door D1 is controlled to be closed and the user is prohibited from entering (S306), and the speaker 13 informs the user that “the ticket information may be invalid”. Is issued (S307).

  As described above, the ticket gate system encrypts the pass ticket information based on the first face image data (first feature data) acquired by photographing the pass ticket purchaser, and is acquired by photographing the passer. The encrypted passport information is decrypted based on the second face image data (second feature data). Therefore, if the ticket purchaser and the passer-by match, the ticket gate of the ticket gate system can decrypt the encrypted passport information, and if the ticket purchaser and the passer-by do not match The ticket gate of the ticket gate system cannot decrypt the encrypted ticket information. That is, the ticket gate of the ticket gate system can determine the validity of the encrypted ticket information based on the decryption result of the encrypted ticket information, for example, based on the decryption error of the encrypted ticket information Chemical pass ticket information can be determined as fraudulent information. In this way, if the ticket purchaser and the passer do not match, the ticket gate system can determine the encrypted pass ticket information as fraudulent information, and the illegal pass ticket acquirer (copy pass ticket user) ) Can be prevented.

  For example, according to the ticket gate system described in the present embodiment, the following operational effects can be obtained.

  (1) It is possible to prevent a single pass ticket on which optically readable pass ticket information is recorded from being used by a plurality of people.

  (2) In the case of not managing the passed ticket ID, it is not necessary to manage the use state of the ticket in the host system, so that the investment cost to the host system can be suppressed.

  (3) In a pass ticket using a two-dimensional bar code, it is difficult to write information to the pass ticket at the time of ticket gate processing. For this reason, fraud prevention that relies on the host system can be considered. The ticket gate system described in the present embodiment can prevent unauthorized use of a pass ticket using a two-dimensional bar code without relying on a host system when the passed pass ticket ID is not managed.

  (4) Since the pass ticket information is encrypted using the face feature amount of the pass ticket purchaser as an encryption key, the contents of the pass ticket information can be concealed.

  (5) Since the pass ticket information is encrypted using the facial feature amount of the pass ticket purchaser as an encryption key, it is possible to dispense with the delivery and setting of the encryption key.

  (6) A technique for encrypting pass ticket information using the facial feature amount of the pass ticket purchaser as an encryption key can also be applied to an IC card pass ticket. Thereby, as mentioned above, the contents of the pass ticket information can be concealed, and the distribution and setting of the encryption key is unnecessary.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
