Description

  The present invention relates to a biometric information authentication system method and apparatus for the purpose of personal authentication.

  In recent years, there has been a growing demand for functions for authenticating a person such as authentication of entrance / exit at an entrance of a condominium, authentication of a passport at the time of entry, authentication of a transaction in an automatic teller machine or the like. Conventionally, password input and authentication by an object have been used as means for authenticating the person. These conventional authentication means have the inconvenience that they cannot authenticate themselves due to forgetting or loss. Also, there is a risk that others will be authenticated due to leakage or theft.

  In view of this, personal authentication technology for performing verification using personal biometric information is becoming widespread. The personal authentication technique using biometric information is a simple authentication means with low risk of forgetting, losing, leaking, theft or the like. Furthermore, there is an advantage that authentication by a third party other than the principal can be prevented. Biometric information used for personal authentication includes fingerprints, palm prints, finger shapes, palm shapes, voice, retina, iris, facial images, dynamic signatures, blood vessel patterns, keystrokes, ear shapes, DNA, lip movements, blinks, etc. is there.

  Biometric information authentication includes “one-to-one authentication” and “one-to-n authentication”. “One-to-one authentication” refers to whether the biometric information of a certifier collected by a biometric information collection unit (for example, a fingerprint sensor) and biometric information registered in advance by the certifier match. This is a method for confirming whether or not. This authentication method requires primary authentication for the authenticator. In the primary authentication, the identity is authenticated by an ID (Identify; Identity) given to the authenticator. In order to perform primary authentication, there is a problem that authentication procedures such as insertion of an ID card and input of an ID number increase, which is complicated. Further, if the issued ID card is lost or the ID number is forgotten, the primary authentication cannot be performed.

On the other hand, the “one-to-n authentication” is to search the biometric information that is the same as the biometric information of the certifier collected by the biometric information collection unit (for example, a fingerprint sensor) from a large number of biometric information registered in advance. This is a method for identifying the certifier. In this method, since primary authentication is not performed, it is not necessary to give an ID to the authenticator. However, it is necessary to search all registered biometric information, which increases the time required for authentication.
In order to shorten the processing time for 1-to-n authentication, a device or the like having high-speed processing capability must be prepared, or the verification logic itself must be improved. In order to solve such a problem, various techniques are disclosed, and as one of them, a technique of narrowing down a collation target by grouping biological information is known as Patent Document 1.

JP 2007-249556 A

  However, depending on the technique disclosed in Patent Document 1, generally, no matter how grouping is performed, the number of biological information included in any group increases. As the population increases, the number of biological information included in each group increases proportionally.

  An object of the present invention is to provide a biometric information authentication technique capable of performing biometric information authentication in a short time without performing primary authentication.

  According to the present invention, a biometric information authentication method includes a biometric information including at least one device that is a target for restricting the use of a user, a server that can communicate with the device, and a biometric information database that registers user biometric information. The biometric information of the user who uses the device is authenticated using an information authentication system.

According to the present invention, the biometric information authentication method comprises:
A user registration step of registering biometric information of at least one user in the biometric information database by the server and using the registered user as a registered user;
A biometric information collecting step of collecting biometric information of a user who is an authentication target by the device;
A device location information collection step of collecting location information of the at least one device by the server;
A portable terminal position information collecting step for collecting position information of the portable terminal of the registered user by the server;
A device vicinity portable terminal search step of searching for a portable terminal existing in the vicinity of each of the at least one device from the position information of the at least one device and the position information of the portable terminal by the server;
A biometric information retrieval step of retrieving biometric information of the registered user corresponding to a portable terminal existing in the vicinity of each of the at least one device from the biometric information database by the server;
The biometric information for collating the biometric information of the registered user existing in the vicinity of the device to be used by the user who is the authentication target and the biometric information of the user who is the authentication target collected in the biometric information collecting step. A matching step;

  ADVANTAGE OF THE INVENTION According to this invention, the biometric information authentication technique which can perform biometric information authentication in a short time, without performing primary authentication can be provided.

  Hereinafter, a first embodiment for carrying out the present invention will be described in detail with reference to the drawings. FIG. 1 is a system configuration diagram showing a first example of the biometric authentication system of the present invention. The biometric information authentication system of this example includes a biometric information authentication device 10 and a biometric information server 20.

  The biometric authentication device 10 is provided in a device 60 used by a user. Examples of the device 60 used by the user include a vending machine, a building entrance, and an automatic cash transaction apparatus. A biometric information storage device 15, a biometric information collection device 16, and a device position information acquisition device 17 are connected to the biometric information authentication device 10.

  The biological information collection device 16 is a device that collects the user's biological information 161 and has a function of collecting biological information from a part of the user's body. As described above, biometric information includes fingerprints, palm prints, finger shapes, palm shapes, voice, retina, iris, facial images, dynamic signatures, blood vessel patterns, keystrokes, ear shapes, DNA, lip movements, blinks, etc. It is done. However, in the following, it is assumed that the biological information is a finger vein. The biological information collection device 16 is assumed to be a finger vein imaging device.

  The biometric information storage device 15 stores biometric information 151 of the user of the mobile terminal that exists in the vicinity of the device. Details of the biological information 151 will be described later with reference to FIG. The device position information acquisition device 17 is configured to acquire the device position information 171 used by the user, and may be a GPS device, for example.

  A biological information database 25 and a memory 26 are connected to the biological information server 20. The biometric information database 251 stores user biometric information 251. The memory 26 stores position information 261 of the mobile terminal, position information 262 of the device, and biometric information 263 of the user of the mobile terminal existing in the vicinity of each device. Details of the information stored in the biological information database 25 and the memory 26 will be described later with reference to FIG.

  The biometric information authentication apparatus 10 and the biometric information server 20 are connected by a network 50 using a public network. A base station 30 is connected to the network 50. A mobile terminal 40 such as a mobile phone is connected to the base station 30 by a wireless line. The base station 30 corresponds to a base station of a mobile telephone operator, and acquires location information 331 of the mobile terminal 40 as needed.

  According to the present invention, the user registers his / her biometric information and the portable terminal ID in the biometric information database 25 in advance. In this registration process, the user may directly transmit his / her biometric information and the portable terminal ID to the biometric information server 20, but may also transmit via the biometric information authentication device 10. Thus, a user who registers biometric information and the ID of the portable terminal in the biometric information database 25 is referred to as a registered user, and a user who is not registered is referred to as a non-registered user.

  The biometric information server 20 collects the position information 261 of all the registered user's portable terminals 40 and the position information 262 of all the devices, and stores them in the memory 26. The biometric information server 20 detects mobile terminals of registered users that exist in the vicinity of each device 60 from the position information 261 of mobile terminals of all registered users and the position information 262 of all devices. Furthermore, the biometric information of the user of the mobile terminal is detected from the ID of the mobile terminal. In this way, the biometric information server 20 searches the registered user's biometric information 263 in the vicinity of each device 60 and stores it in the memory 26. The biometric information server 20 periodically transmits biometric information 263 of a registered user that exists in the vicinity of each device 60 to each device 60. Therefore, the biometric information 151 of the registered user that always exists in the vicinity of the device 60 is stored in the biometric information storage device 15 of the biometric information authentication device 10.

  It is assumed that the registered user always carries the mobile terminal 40. The user of the device 60 engages the biological information collecting device 16 with a part of his / her body. The biometric information authentication device 10 collates the biometric information 161 of the user collected by the biometric information collection device 16 with the biometric information 151 of the registered user stored in the biometric information storage device 15. As a result of the collation, when the biometric information that matches the biometric information 161 of the user is included in the biometric information 151 of the registered user, the user authentication of the user of the device 60 is completed. The device 60 gives, for example, use permission to the registered user. According to the present invention, only users who have the same biological information as the biological information 151 stored in the biological information storage device 15 among the users of the device 60 are authenticated. In other words, the device 60 can be used only by registered users who have previously registered their own biometric information and the ID of the mobile terminal in the biometric information database 25 and are carrying their own mobile terminal.

  The biometric information authentication device 10 receives biometric information 263 of a registered user transmitted from the biometric information server 20 at a predetermined cycle, and stores the biometric information receiving device 101 and the biometric information storage device in the biometric information storage device 15. The biometric information collating device 102 for collating the biometric information 151 of the registered user stored in the biometric information 151 with the biometric information 161 of the user collected via the biometric information collecting device 16 and the biometric information server 20 The position information transmitting device 103 of the device that transmits to the device. Details of the functions of these devices constituting the biometric authentication device 10 will be described later.

  The biometric information authentication device 10 and the biometric information server 20 may be a computer that includes a memory, an arithmetic processing device, a hard disk, an input device, and an output device or a display device. The functions of the biometric information authentication apparatus 10 and the biometric information server 20 may be configured by a program that can be executed by a computer.

  The biometric information server 20 collects the biometric information registration device 201 that registers the biometric information 251 transmitted from the user in the biometric information database 25 and the location information of the registered user's mobile terminal transmitted from the base station 30 in a predetermined cycle. The portable terminal position information collecting device 202 that stores the information in the memory 26, the device position information collecting device 203 that collects the device position information 171 transmitted from the biometric information authentication device 10 and stores it in the memory 26, and the memory 26 Search device 204 for searching for a portable terminal existing in the vicinity of each device from the position information 261 of the portable terminal and the position information 262 of the device stored in, and searching for biometric information of the registered user, and in the vicinity of each device The biometric information distribution device 205 distributes the biometric information 263 of the registered user that exists to each biometric information authentication device 10. Details of the functions of these devices constituting the biological information server 20 will be described later.

  With reference to FIG. 2, a process of storing the location information 331 of the registered user's mobile terminal in the memory 26 of the biological information server 20 will be described. As shown in FIG. 1, the base station 30 acquires the position information 331 of all the mobile terminals 40 in its own jurisdiction area, and transmits it to the biological information server 20 at a predetermined cycle. This cycle is referred to as a portable terminal location information registration cycle. The biometric information server 20 stores the location information of the registered user's mobile terminal in the memory 26 based on the location information of the mobile terminal transmitted from the base station 30.

  The position of the mobile terminal is easy to change. Therefore, in order to register the latest position of the registered user's mobile terminal in the memory 26, the mobile terminal position information registration cycle should be relatively short. The portable terminal location information registration cycle may be, for example, 10 seconds, 1 second, and 1/10 second. The memory 26 always holds the latest position information of the mobile terminals 40 of all registered users existing in the jurisdiction area of the base station 30.

  With reference to FIG. 3, processing for distributing biometric information 151 of a registered user existing in the vicinity of each device from the biometric information server 20 to the biometric information authentication apparatus 10 will be described. All the biometric information authentication devices 10 transmit the device position information 171 to the biometric information server 20 at a predetermined cycle or at a predetermined time. This cycle is referred to as a device position information registration cycle. The predetermined time is, for example, when the device 60 and the biometric information authentication apparatus 10 are installed or when the positions thereof are changed.

  The biometric information server 20 distributes the biometric information 151 of the registered user existing in the vicinity of each device to all the biometric information authentication devices 10 for each device in a predetermined cycle. That is, for each device, the biometric information server 20 searches for a registered user's mobile terminal existing in the vicinity of the device, searches for the biometric information 151 of the registered user, and retrieves the biometric information authentication device 10 of the device. Deliver to. This cycle is referred to as a biological information distribution cycle.

  It is unlikely that the position of the device will change. Accordingly, the device position information registration cycle may be relatively long, for example, 24 hours. On the other hand, the position of the mobile terminal existing in the vicinity of the device is likely to change. Therefore, in order to register the latest data as the biometric information 151 of the registered user existing in the vicinity of the device in the biometric information storage device 15, the biometric information distribution cycle should be relatively short. The biological information distribution cycle may be, for example, 10 seconds, 1 second, 1/10 second, or the like.

  Thus, according to this example, the biometric information of the registered user existing in the vicinity of each device 60 is stored in the memory 26 of the biometric information server 20 and the biometric information storage device 15 of the biometric information authentication device 10. The biological information 151 of the biological information storage device 15 is updated with the latest information in the biological information distribution cycle.

  Referring to FIG. 4, device position information 171 acquired by biometric information authentication device 10, biometric information 151 stored in biometric information storage device 15, position information 331 of mobile terminal 40 acquired by base station 30, An example of biometric information 251 registered in the biometric information database 25 will be described.

  The device position information 171 includes a device ID 1711, a device IP address 1712, and device position information (longitude / latitude) 1713. The ID 1711 is identification data that uniquely determines the device 60. The IP address 1712 is a destination address used when the biometric information server 20 transmits the biometric information 263 of the registered user to the biometric information authentication apparatus 10. The device position information 1713 is the longitude and latitude of the device 60. The latitude and longitude of the device 60 are the same as the latitude and longitude of the biometric authentication device 10. The location information 1713 is obtained by the location information acquisition device 17 of a device such as a GPS device provided in the biometric authentication device 10.

  The device location information 171 is transmitted from the biometric information authentication apparatus 10 to the biometric information server 20 in the device location information registration cycle. The biological information server 20 stores the device position information 171 in the memory 26. Accordingly, the device position information 262 stored in the memory 26 is the same as the device position information 171 obtained by the device position information acquisition device 17.

  The biometric information 151 stored in the biometric information storage device 15 is biometric information of a registered user that exists in the vicinity of the device. In general, there may be many different people near the device 60. The biometric information storage device 15 of the biometric authentication device 10 stores biometric information of registered users among persons existing in the vicinity of the device 60. The registered user's biometric information 151 stored in the biometric information storage device 15 is the same as the registered user's biometric information 263 stored in the memory 26.

  The position information 331 of the portable terminal 40 acquired by the base station 30 includes the current position information 3311 of the portable terminal 40, that is, the current latitude and longitude. Of the location information 331 of the mobile terminal acquired by the base station 30, location information 261 of the registered user's mobile terminal is stored in the memory 26.

  The biometric information 251 registered in the biometric information database 25 includes a portable terminal ID 2511 and biometric information 2512. The portable terminal ID 2511 and the biological information 2512 are information relating to the registered user. The registered user can change the ID 2511 and the biometric information 2512 of the portable terminal, but the information registered by the user is first stored as it is unless changed.

  With reference to FIG. 5, processing in the biometric information authentication apparatus 10 provided in the device (vending machine) 60 will be described.

  In step S101, the biological information collection device 16 collects the biological information 161 of the user of the device. That is, the user inserts a finger into the finger vein imaging device. The finger vein imaging device acquires an image of the finger vein. In step S102, the biometric information authentication device 10 stores the biometric information 161 of the user acquired by the biometric information collection device 16 in a memory. That is, the image of the finger vein of the user of the device is stored in the memory. In step S <b> 103, the biometric information collation device 102 collates the biometric information 161 of the user of the device stored in the memory with the biometric information 151 of the registered user stored in the biometric information storage device 15. The biometric information storage device 15 stores biometric information 151 of a registered user received by the biometric information acquisition / reception device 101 from the biometric information server 20.

  As a result of the collation, if the biometric information 161 identical to the biometric information 161 of the user of the device is included in the biometric information 151 of the registered user, the process proceeds to step S104 and the purchase procedure is started. If it is determined that the biometric information 151 of the registered user is not included as a result of the collation, the process proceeds to step S105. In step S105, the biometric information server 20 is requested to distribute the biometric information of the registered user existing in the vicinity of the device. In other words, the device position information transmitting apparatus 103 transmits the device position information 171 to the biological information server 20. The device position information 171 is acquired by the device position information acquisition device 17.

  In step S106, the biometric information server 20 distributes biometric information of the registered user existing in the vicinity of the device. The biometric information receiving device 101 receives biometric information of a registered user distributed from the biometric information server 20. In step S107, the biological information receiving apparatus 101 stores it in the biological information storage device 15. That is, the biometric information 151 stored in the biometric information storage device 15 is updated. In step S108, the biometric information collation apparatus 102 collates again the biometric information 161 of the user of the device stored in the memory with the biometric information 151 of the registered user stored in the biometric information storage apparatus 15. As a result of checking, if the biometric information 161 identical to the biometric information 161 of the user of the device is included in the biometric information 151 of the registered user, the process proceeds to step S104, the authentication process is terminated, and the purchase procedure is started. As a result of the collation, if it is not included in the biometric information 151 of the registered user, the process proceeds to step S109. In step S109, NG is displayed on the display unit of the device, and the authentication process is terminated.

In step S <b> 605, the biometric information server 20 searches for a mobile terminal that exists in the vicinity of the device, and transmits the biometric information of the registered user to the biometric authentication device 10 of each device 60.

  When the user uses the device (vending machine) 60, the biometric authentication device 10 authenticates the user. That is, the biometric authentication device 10 collates the user's biometric information 161 acquired from the biometric information collection device 16 with the registered user's biometric information 151 stored in the biometric information storage device 15. If the same biometric information as the user biometric information 161 is not included in the registered user biometric information 151 as a result of the collation, the biometric authentication device 10 sends the biometric information server 20 to the biometric information server 20 in step S606. Position information (latitude / longitude) is transmitted to request distribution of biometric information of a registered user existing in the vicinity of the device. In step S <b> 607, the biometric information server 20 transmits biometric information of the registered user existing in the vicinity of the device to the biometric authentication device 10. The biometric authentication device 10 checks biometric information again.
