Description

  The present invention relates to an IC card user authentication system and an IC card user authentication method.

  Currently, IC cards are used for various purposes such as licenses, passports, employee cards, etc., and are used for information management and personal identification regarding the owner. Particularly in the field of automobiles, in addition to the purpose of preventing theft of vehicles, in the new car life such as license authentication at the time of car sharing, the use of a driver's license converted into an IC card is expected.

  Since the IC card is small and lightweight, it has the feature of being easy to carry, but it can be easily stolen, borrowed and transferred, and the impersonation problem impersonating the owner of the IC card has become apparent.

  As a means for preventing the above-mentioned impersonation, a method of registering information (for example, an authentication password) that only the IC card owner knows in advance in an authentication system, and requesting input or presentation of the registered information at the time of authentication Can be considered.

  However, the above-described method requires the owner to store or record the authentication password in advance, which is troublesome for the user and has a problem of information leakage through theft or loss of the recorded medium.

  Further, when the user forgets the pre-registration information, there is a problem that the necessity of re-registration occurs or the use becomes impossible depending on the case.

  In response to the above problem, an IC card user authentication system that authenticates a user by storing face image data in an IC card and collating the face image data with a result of photographing a user's face. And IC card user authentication methods have been proposed (for example, Patent Document 1).

  According to this authentication system and authentication method, not only does it prevent the user from impersonating by collating the face image data held in the IC card with the actual captured video, but it is necessary for authentication. Since it is not necessary for the user to memorize or record the information, the burden on the user can be reduced.

JP 2012-68924 A

  However, since the conventional technology uses a two-dimensional image of the front of the face, the authentication system misrecognizes that the user is a legitimate user by holding a photograph of the face of the authorized user in front of his / her face. There was a problem to do. Further, in the conventional technique, it is necessary to fix and install a photographing camera that plays an important role as an authentication system in the vehicle, and there is a problem regarding the burden of introducing the authentication system.

  The present invention was devised in view of the above-described problems, and provides an IC card user authentication system and an IC card user authentication method for reducing the burden of introducing an authentication system and reliably preventing impersonation. The purpose is to do.

  An IC card user authentication system according to the present invention includes an IC card reading unit for reading information recorded on an IC card, a face image information acquiring unit for acquiring face image information of a user of the IC card, and registration in advance The present invention is directed to a user authentication system for an IC card installed in a vehicle, which includes a recording unit that records IC card information of an authorized person to be authenticated and facial image information of the authorized person.

  Then, the IC card user authentication method of the IC card user authentication system is such that the IC card user authentication system is subject to authentication approval by the IC card owner from the IC card information read from the IC card reader. A first discriminating step for discriminating whether or not the IC card is a person, a second discriminating step for discriminating whether or not the owner of the IC card and the user of the IC card are the same person, The determination means of 1 determines that the owner of the IC card is a person to be approved for authentication, and the owner of the IC card and the user of the IC card are the same person by the second determination means. And a control process for performing approval control that permits operation of the vehicle only when it is determined.

  According to the configuration and method as described above, it is possible to reliably prevent forgery during IC card user authentication, and to effectively reduce the burden of introducing an authentication system.

The authentication device control unit 11 includes the acquired IC card information of the IC card 4, video information (hereinafter referred to as user face video information) for confirming the user's face information received and acquired from the camera 3, and authentication information Based on the information stored in the storage memory 14, it is determined whether the owner of the IC card 4 is qualified to drive a vehicle equipped with the system, and the user It is confirmed whether it is the same person as the owner of 4.

  The user face image information received and acquired from the camera 3 is very important in the present invention, and will be described in detail later.

  The camera video reception unit 12 is a part that receives video information captured by the camera 3 using wireless communication (for example, WLAN), which is controlled by the authentication device control unit 11. Information received by the camera video receiver 12 is transmitted to the authentication device controller 11 via the camera video receiver 12.

  The user interface 13 is a part for exchanging information with the user U1 during the IC card authentication process, and specifically shows a touch panel display. The user interface 13 is controlled by the authentication device control unit 11 and displays video data or notifies the coordinate information of the touch panel operated by the user U1.

The information for authentication includes IC card information (hereinafter referred to as registered IC card information) of a driver's license, and face image information (hereinafter referred to as registered face image information) of the qualified person who is qualified to drive a vehicle. ).

The registered IC card information and the registered face image information are managed in association with each qualified person.

  That is, when the registered IC card information of the qualification holder A is registered IC card information A and the registered face image information of the qualification holder A is registered face image information A, the registered IC card information A and the registered face image information A are Managed in pairs. The registered face video information is information recorded and recorded by the same method as the above-described face video information.

  As described above, the IC card reader interface 15 is a connector for connecting to the IC card reader 2 with a wired cable (for example, Universal Serial Bus (hereinafter, USB)), and is connected to the authentication device control unit 11. .

  Next, the IC card reader 2 will be described with reference to FIG. As shown in FIG. 2, the IC card reader 2 has an IC card reader control unit 21 that controls the entire IC card reader 2, and an NFC communication unit described later with the IC card reader control unit 21 as a center. 22 and a vehicle authentication device interface 23 are connected.

  The NFC communication unit 22 is controlled by the IC card reader control unit 21 and communicates with the IC card 4 by electromagnetic waves via the NFC communication antenna 24 to acquire information held by the IC card 4.

  The IC card reader controller 21 notifies the in-vehicle authentication device 1 of the acquired information of the IC card 4 via the vehicle authentication device interface 23.

  Next, the configuration of the IC card 4 will be described with reference to FIG. As shown in FIG. 3, the IC card 4 includes an IC card control unit 41, an NFC communication unit 42, an IC card information storage memory 43, an NFC communication antenna 44, a power circuit 45, and the like.

  The power supply circuit 45 generates a power supply for operation from a transmission signal from the IC card reader 2 received via the NFC communication antenna 44. The generated power supply is used for each of the IC cards 4 in addition to the IC card control unit 41. Supplying to the block.

  The IC card control unit 41 is operated by the power generated by the power circuit 45. In addition, the IC card control unit 41 reads information stored in the IC card information storage memory 43 and transmits the information to the IC card reader 2 via the NFC communication unit 42 and the NFC communication antenna 44.

  The IC card information storage memory 43 is constituted by a semiconductor memory such as an EEPROM, and is controlled by the IC card control unit 41. In the IC card information storage memory 43, in addition to the identification information for identifying the IC card 4, data corresponding to the use of the IC card 4 (for example, data relating to a driver's license) is recorded. Hereinafter, the information stored in the IC card information storage memory 43 is referred to as IC card information.

  The authentication process of the authentication system using the IC card configured as described above will be described with reference to the flowcharts of FIGS. The processing in FIGS. 4 and 5 is mainly performed by the in-vehicle authentication device 1.

In this example, it is assumed that all elements constituting the authentication system in FIG. 1 are in an activated state (standby state). Further, the WLAN communication between the camera 3 and the in-vehicle authentication device 1 is already in a connected state (that is, a state in which the authentication process of the WLAN communication between devices is completed), and the video information captured by the camera 3 is the in-vehicle authentication device. 1 is already received by streaming, and the user face image information is owned by the authentication device control unit 11 when the user U1 acquisition start button displayed on the user interface 13 is pressed by the user U1. It is assumed that the acquisition can be started in the RAM area.

  In addition, it is assumed that the authentication information storage memory 14 holds vehicle driving qualification owner list information and face video information associated with the driving qualification owner.

  FIG. 4 shows that the owner registered in the IC card 4 captured by the IC card user authentication system in FIG. 1 is a person who is qualified to drive a vehicle equipped with the system, and The collation with the face image information from the camera 3 is used to confirm that the registered person of the IC card 4 and the user U1 who is going to drive the vehicle equipped with the system are the same person. It is a flowchart when authenticating.

  First, at the start of the authentication process, the authentication device control unit 11 stands by in a state where the authentication waiting state is displayed on the user interface 13 (step S101), and whether or not the IC card 4 is captured by the IC card reader 2 or not. Is determined (step S102).

  Until the IC card 4 is captured by the IC card reader 2, the process returns to step S <b> 101 and keeps the standby state. If it is determined that the IC card 4 has been captured by the IC card reader 2, the process proceeds to processing for acquiring information on the IC card 4 (step S103).

  The authentication device control unit 11 acquires the IC card information recorded on the IC card 4 through the IC card reader 2 through the IC card reader interface 15 and holds it in the RAM area of the authentication device control unit 11 (Step S103). Hereinafter, the IC card information of the IC card 4 is referred to as IC card information A.

  The authentication device control unit 11 searches the registered IC card information recorded in the authentication information storage memory 14, and determines whether or not the IC card information A acquired in step S103 is included in the registered IC card information. Is determined (step S104).

  When the IC card information A is included in the list of registered IC card information, the process proceeds to a process of collating the user with the IC card owner (step S105). When the IC card information A is not included in the registered IC card information, the process proceeds to an authentication failure process (step S108).

  The authentication device control unit 11 performs user face image information acquisition / collation processing to confirm whether the owner of the IC card 4 and the user U1 are the same person (step S105). When the user face image information acquisition / collation process is completed, the process proceeds to a process of determining a collation result (step S106). Here, user face image information acquisition / collation processing will be described with reference to FIG.

  FIG. 5 shows that the user face image information photographed by the camera 3 is acquired and collated with the registered face image information, so that the owner of the IC card 4 and the user U1 are the same person. It is a flowchart at the time of judging.

  The authentication device control unit 11 captures the user face image information, the content that prompts the user to start acquiring the user face image information, and “user image acquisition start” that causes the in-vehicle authentication device 1 to clearly indicate the acquisition start by the user. It waits while displaying the described button on the user interface 13 (step S105_1), and determines whether or not it is detected that the “user video acquisition start” button has been pressed (step S105_2).

  If it is determined that the “user video acquisition start” button has been pressed, the process proceeds to a process of acquiring user video information (step S105_3). If the “user video acquisition start” button is not pressed, the process waits until the button is pressed while maintaining the state of step S105_1.

  Here, the user face image information will be described with reference to FIG. FIG. 6A illustrates a method for acquiring user face image information, and FIG. 6B illustrates user face image information obtained when the image is captured by the operation illustrated in FIG. The image is a diagram.

  FIG. 6A is a view of the user U1 looking down from above, and is considered in a horizontal direction with respect to the drawing. The front face of the user U1 is defined as a phase reference (± 0 degrees), the center of the user U1 is defined as a rotation axis, the clockwise direction is defined as a negative phase, and the counterclockwise direction is defined as a positive phase.

  At this time, the camera 3 captures the user face image information at a time of 180 degrees from +90 degrees to −90 degrees with the user U1 as the center of the axis, and rotates the image counterclockwise. It is a feature. This operation starts from a position of +90 degrees when the above-mentioned “user video acquisition start” button is pressed.

  FIG. 6B is an image diagram of user face image information when the image is taken by the operation of FIG. As a characteristic example in FIG. 6B, face video information from a total of five directions of −90 degrees, −45 degrees, ± 0 degrees, +45 degrees, and +90 degrees is displayed. Therefore, it is possible to continuously acquire user face image information from a finer phase.

  In the video imaged by the method as described above, the face information of the user U1 starts from the left side, passes through the front, and reaches the right side. It will be. That is, by confirming the face of the user U1 from all directions, it is possible to virtually obtain three-dimensional information, and collation from the three-dimensional face information is possible.

  That is, it is possible to reliably prevent impersonation using an image having only information on the problem plane in the conventional technique. Furthermore, it is possible to prevent impersonation by pre-recording by using real-time information acquisition by streaming.

  Here, it returns to the flowchart of FIG. Upon detecting that the “user video acquisition start” button has been pressed, the authentication device control unit 11 displays a “user video acquisition end” button and performs processing for acquiring user video information (step S105_3). .

  The user image information acquisition method is as described above, and user face image information received by streaming through the camera image receiving unit 12 is recorded until “user image acquisition end” is pressed by the user U1. Keep holding.

  At the timing when “user video acquisition end” is pressed by the user U1, the process proceeds to a process of determining whether or not the acquired user face video information can be collated (step S105_4).

  In step S105_3, the authentication device control unit 11 performs real-time image processing on the received user face video information, and any part of the distributed video information becomes the user's face. The user's face orientation is recorded and held while judging whether or not it contains information necessary for collation.

  After acquiring the user face image information, the authentication device control unit 11 determines whether the acquired user face image information can be compared with the registered face image information (step S105_4).

  That is, the determination is made based on whether or not the acquired user face image information includes a determination criterion for checking that the user and the IC card owner are the same person.

  When it is determined that the acquired user face video information can be collated with the registered face video information, the process proceeds to a collation process (step S105_6). If it is determined that the acquired user face image information cannot be compared with the registered face image information, the process again proceeds to the process of prompting the user face image information to be acquired (step S105_5).

  When it is determined that the acquired user face image information cannot be compared with the registered face image information, the authentication device control unit 11 prompts the user interface 13 to shoot the user image information again, and “user image” "Acquisition start" is displayed, and the process returns to step S105_2.

  When it is determined that the acquired user face image information can be compared with the registered face image information, the authentication device control unit 11 performs a comparison process between the user face image information and the registered face image information (step S105_6).

  Here, with regard to the collation technique between the user face image information and the registered face image information, it is possible to adopt the judgment standards of various known techniques by using them as correlation judgment criteria in association with the rotation phase.

  For example, a method of extracting a plurality of structural features and using a trajectory according to the rotation phase of the plurality of structural features as a reference for collation or a method of performing pattern matching of the face information portion for each rotation phase may be used. . After the collation process in this step is completed, the process proceeds to the process of judging the collation result (step S105_7).

  The authentication device control unit 11 determines whether the face information included in the user face image information matches the face information included in the registered face image information based on the result of the comparison between the user face image information and the registered face image information. Is determined (step S105_7).

  When it is determined that the face information included in the user face image information matches the face information included in the registered face image information, a result that the user U1 is the same person as the IC card 4 is retained as a comparison result ( Step S105_8), the user face image information acquisition / collation process is completed.

  When it is determined that the face information included in the user face image information and the face information included in the registered face image information do not match, a result that the user U1 is not the same person as the IC card 4 is retained as a comparison result. (Step S105_9) The user face image information acquisition / collation process is completed.

  From here, it returns to FIG. 4 again and demonstrates. The authentication device control unit 11 that has completed the user face image information acquisition / collation process in the flowchart as shown in FIG. 5 determines whether the user U1 is the same person as the owner of the IC card 4 based on the collation result described above. If it is determined that the person is the same person, the process proceeds to an authentication success process for the user U1 (step S107). If it is determined that the person is not the same person, the authentication failure process is performed for the user U1. The process proceeds to (Step S108).

When it is determined that the user U1 is the same person as the owner of the IC card 4, the authentication device control unit 11 performs authentication for permitting the user U1 to drive a vehicle equipped with this system. A success process is performed (step S107), and the process is completed.

  Further, when the user U1 determines that the user is not the same person as the owner of the IC card 4, the authentication device control unit 11 informs the user U1 that the authentication has failed, so the authentication process has failed to the user interface 13. Control is performed to display the effect, and the display is held for a certain time (for example, 5 seconds). Thereafter, all information (for example, registered IC card information and user face image information) acquired in the course of the authentication process is deleted, and the process returns to the standby state in step S101 (step S108).

  As described above, according to the present embodiment, it is possible to reliably prevent impersonation at the time of IC card user authentication, and since it is possible to use a brought-in device for a camera necessary for authentication, the authentication system It is possible to effectively reduce the introduction burden.

  In particular, the carrying of this embodiment can surely prevent the user from impersonating the user in confirming that the owner of the IC card 4 and the user of the apparatus equipped with the authentication system are the same person. This technique is particularly useful when it is desired to prevent unauthorized driving or to authenticate the license holder in car sharing.
