--- System configuration ---
Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a configuration diagram of a biometric authentication system 100 in the present embodiment. A biometric authentication system 100 (hereinafter, system 100) in the present embodiment is a computer that can execute biometric authentication processing at high speed even in a situation where a large number of templates (biometric information for authentication) are registered. For example, it is possible to assume a server device that performs a biometric authentication process required when a user enters or leaves a commercial facility such as an amusement park or uses the facility. Of course, in addition to these examples, various situations in which biometric authentication processing is performed (ex: entry / exit at government offices and government offices, reception and provision of services, immigration control that requires biometric authentication at airports, ports, stations, etc.) The biometric authentication system of this embodiment can be applied to business and the like.

  The system 100 reads out the program 102 stored in the storage unit 101 such as a non-volatile memory to the memory 103 and executes it by the CPU 104 which is an arithmetic device in order to realize the function of executing the biometric authentication method. The system 100 includes various buttons generally provided in a computer device, an input interface 105 such as a keyboard, an output interface 106 such as an LED and a display, and a reading device 200 that executes biometric information reading for a person to be authenticated. A communication means 107 for communicating is provided.

  Next, functional units that are configured and held by the system 100 based on the program 102 will be described. In addition, the system 100 includes a member database 125 that stores the biometric information registrant's attribute, the biometric information registrant's biometric information, and the corresponding biometric information registrant's symbol data in association with each other. .

  The system 100 accepts data input from the person to be authenticated at the input interface 105, compares the data received here with the attributes of each biometric information registrant in the member database 125, and biometric information registration with matching attributes. The target person narrowing-down means 110 which specifies a person as an authentication object person is provided.

  In addition, as data from the person to be authenticated who accepts input at the input interface 105, for example, a member number when the person to be authenticated is a member of the amusement park can be assumed. This member number is connected to the reception terminal 300 (in addition to the form in which the system 100 obtains what is input by the person to be authenticated at the reception terminal 300 (and the input interface 105 connected thereto) installed in the reception facility or the like. form to obtain performing reading of membership cards 1 in an IC card reader 150 included in the input interface 105) that are also conceivable. In this case, the membership card 1 has an IC chip 10 in which data such as a member number, a member's name, a credit card number, a finger vein template 1 and a finger vein template 2 are recorded. It is equipped. The “credit card No.” data is, for example, data necessary as settlement data when a member uses an attraction or purchases a product / service at a store in the commercial facility. Further, “finger vein template 1” and “finger vein template 2” are biometric information of members. The biometric information of the biometric information registrant is not registered in advance in the member database 125 of the system 100, but the biometric information is registered in the member card 1, and the biometric information is taken into the authentication database 126 from the member card 1. It is conceivable that the biometric information is stored in the member card 1 in this way. Note that the two types of biometric information “finger vein template 1” and “finger vein template 2” are stored in the member card 1 because, for example, one hand is a right hand and the other hand is a left hand. 2 shows a situation in which two patterns of biometric information are prepared in preparation for a reading defect due to the above.

  Further, the system 100 specifies the biometric information of the biometric information registrant corresponding to the authentication target person in the member database 125, and the data of the corresponding biometric information group specified here is stored in the storage unit 101 as the authentication database 126. An authentication data specifying unit 111 for storing is provided.

And when the biometric information that matches the read biometric information is present in the biometric information group, the authentication is successful, and when the biometric information that matches the read biometric information does not exist in the biometric information group, the authentication is unsuccessful. The authentication execution means 112 is provided. The authentication execution means 112 is configured so that the biometric information that matches the read biometric information does not exist in the biometric information group and the authentication is unsuccessful, and the biometric information registered in the member database 125 and the read biometric information. Verification with information may be performed.

  The system 100 further includes output means 113 for outputting the authentication success or authentication failure data to the output interface 106.

  In addition, after the authentication database 126 is stored in the storage unit 101, the system 100 accepts designation of symbol data from the person to be authenticated at the reception terminal 300 (the input interface 105 connected thereto) The secondary authentication data specifying means for matching the biometric information group data in the authentication database 126 and specifying the biometric information of the biometric information registrant who matches the symbol as the secondary authentication database 127. 114 may be provided.

  In addition, the system 100 acquires read biometric information read by the reader 200 of the commercial facility from the reader 200 from the reader 200, and the read biometric information is stored in the secondary authentication database 127. The biometric information that matches the read biometric information exists in the biometric information group, and the authentication is successful, and the biometric information that matches the read biometric information does not exist in the biometric information group. The secondary authentication execution means 115 may be provided.

  The secondary authentication execution means 115 collates the read biometric information with the biometric information group in the secondary authentication database 127, and when biometric information matching the read biometric information does not exist in the biometric information group. If the read biometric information is collated with the biometric information registered in the authentication database 126 and the biometric information in the authentication database 126 can be retrieved by the collation, the authentication success is confirmed. You can do it. In this case, the secondary authentication data specifying unit 114 fails to authenticate the collation between the read biometric information and the biometric information group of the secondary authentication database 127, and stores the read biometric information and the authentication database 126. For the person to be authenticated who has succeeded in the verification with the registered biometric information, the symbol data set for the person to be authenticated in the authentication database 126 is specified, and information on the corresponding symbol data is output to the output interface 106. indicate.

  In the system 100, the target person narrowing means 110 accepts data input at the input interface 105 such as the reception terminal 300 and accepts the data as a person to be authenticated who enters a predetermined area such as a commercial facility. The data (for example, member No.) may be compared with the attribute of each biometric information registrant in the member database 125, and the biometric information registrant with the same attribute may be specified as the authentication target person.

  In this case, the authentication data specifying unit 111 specifies the biometric information of the biometric information registrant corresponding to the authentication target person in the member database 125, and the data of the corresponding biometric information group specified here is used for the visitor. The data is stored in the storage unit 101 as the authentication database 125.

  Further, the secondary authentication data specifying means 114 is installed in a predetermined facility (eg, amusement park attraction) in the predetermined area after the authentication database 126 for visitors is stored in the storage means 101. The input interface 105 (connected to the attraction reception terminal) accepts designation of symbol data from a person to be authenticated who desires to use the predetermined facility, and the symbol data received here is used as an authentication database for the visitor. The biometric information of the biometric information registrant who matches the biometric information group data of 126 is identified as the secondary authentication database 127.

  Still further, the secondary authentication execution means 115 acquires the read biometric information read by the reader 200 from the reader 200 from the person to be authenticated who wishes to use the predetermined facility. The biometric information group in the secondary authentication database 127 is collated, and when biometric information matching the read biometric information exists in the biometric information group, authentication is successful, and biometric information matching the read biometric information is the biometric information. If it does not exist in the group, the authentication is unsuccessful.

  Further, the output means 113 sends a notification of permission to use the predetermined facility when the authentication is successful, and notifies the use permission of the predetermined facility when the authentication is unsuccessful to the output interface 106 installed at the predetermined facility. Output.

  Further, the system 100 accepts an instruction to select symbol data by the biometric information registrant at the input interface 105 connected to the accepting terminal 300 before the processing of the secondary authentication data specifying means 114, and performs the selection. Symbol data registration means 116 may be provided which stores symbol data information corresponding to the instruction in the member database 125 in association with the biometric information of the biometric information registrant.

  In the system 100, the symbol data registration unit 116 converts the biometric information registered in the member database 125 into a set symbol data type when receiving a symbol data selection instruction from the biometric information registrant. A list in which the number of biological data is specified and symbol data types are specified in order from the predetermined reference number is generated, and information on symbol data of a predetermined rank or higher in the list is selected as selectable symbol data (the receiving terminal 300 Or the like on the output interface 106.

  The symbol data is determined for each biometric information group obtained by dividing biometric information registered in the member database 125 by a predetermined number, and the member database 125 for biometric information registrants whose biometric information belongs to the biometric information group. Can be assumed to be set in In this case, when biometric information is registered in the member database 125, the biometric information registered in the member database 125 is counted to form a biometric information group for each predetermined number, and the biometric information to which the registered biometric information belongs. A group (for example, a group whose registration date is the last) is specified, and symbol data information corresponding to the specified biometric information group is stored in association with the registered biometric information in the member database 125. The system 100 may include the symbol data setting unit 117. At this time, the system 100 may include symbol data notification means 118 for displaying symbol data information corresponding to the biometric information group to which the registered biometric information belongs on the output interface 106.

  Further, the system 100 detects the arrival of a predetermined time by using a clock function 130 or the like that is naturally provided as a computer (eg, the predetermined time is preset in the clock function 130 as a timer time) and detects the arrival of the predetermined time. deletes the authentication database 126 stored in the storage unit 101 may be provided with a first deletion unit 119.

  In addition, the system 100 detects input of predetermined attribute data (eg, logoff data or exit notification data) by an authenticated person at the input interface 105, and detects input of the predetermined attribute data by the authenticated person. If, deletes the biometric information of the person to be authenticated from the in authentication database 126 may be provided with a second deletion unit 120.

  Note that the reader 200 communicating with the system 100 executes, for example, an appropriate biometric information reading process such as a vein such as a finger or a palm, a fingerprint, an iris, or the like for an authenticated person who is a user of the amusement park. Device. Therefore, a communication interface for communicating with a reader for reading biometric data necessary and its controller and the system 100. In addition, an output interface such as a display or a speaker that receives an authentication result notification from the system 100 and outputs it may be provided.

  The functional units 110 to 120 in the system 100 described so far may be realized as hardware, or as a program stored in an appropriate storage device such as a memory or an HDD (Hard Disk Drive). Also good. In this case, the CPU of the system 100 reads the corresponding program from the storage device into the memory in accordance with the program execution, and executes it.

--- Database structure example ---
Next, the structure of the database used by the biometric authentication system 100 in this embodiment will be described. FIG. 2 is a diagram illustrating a data configuration example of (a) the member database 125 and (b) the authentication database 126 according to the present embodiment.

  The member database 125 is a database that stores the attributes of the biometric information registrant, the biometric information of the biometric information registrant, and the symbol data of the biometric information registrant in association with each other. The member database 125 uses, for example, a member type, a name, a credit card number, a registration mark as symbol data, a finger vein template 1 as a biometric information, and a finger using a “member No.” that uniquely identifies a biometric information registrant as a key. It is an aggregate of records in which data such as the vein template 2 is associated. The registration mark (hereinafter referred to as a registration mark) as the symbol data is one that is received in response to a selection instruction from the biometric information registrant at the input interface 105 and stored according to the selection instruction. For example, if a member selects “Roller Coaster” as his / her registration mark in the input interface 105, the information of “Roller Coaster” is set in the registration mark field in the record of the member. That is, a registration mark is set according to the request of a member who is a biometric information registrant. Alternatively, the registration mark is set for each biometric information group obtained by dividing biometric information registered in the member database 125 by a predetermined number, and is set for a biometric information registrant to which biometric information belongs to the biometric information group. Also good.

  Further, the authentication database 126 specifies biometric information of a biometric information registrant (= authenticated person) whose attributes match the input data (eg, member No.) of the person to be authenticated from the member database 125. This is data of the corresponding biological information group. The authentication database 126 includes, for example, a member's name, credit card number, registration mark, finger vein template 1, finger vein template 2, etc., using the “member No.” of the person who has been authenticated as a key. It is a collection of records associated with data. In addition, when the person to be authenticated uses an accommodation facility attached to the amusement park, the room number and locker No. are also registered. The room number and locker No. are data having the same significance as the registration mark. For example, the data of the room number assigned to the user who checked in to the accommodation facility is acquired from the front terminal or the like of the accommodation facility by the system 100 and is associated with the biometric information of the user and the authentication database 126. Set to. Thereafter, when the user enters the room, the biological information is read by the biological information reader installed at the entrance of the room, and the read biological information is sent from the reader to the system 100. When collating the read biometric information with the authentication database 126, the biometric information (finger vein template in the example of FIG. 2B) of the record associated with the corresponding room number can be read and collation can be executed one-on-one from the beginning. .

  FIG. 3 is a diagram illustrating a data configuration example of (a) the secondary authentication database 127 and (b) the settlement database 128 according to the present embodiment. In the secondary authentication database 127, after the authentication database 126 is stored in the storage means 101, the system 100 accepts designation of a registration mark (symbol data) from the person to be authenticated at the input interface 105, The biometric information of the biometric information registrant who matches the registration mark is used as a database by collating the registration mark received in step 1 with each biometric information group data in the authentication database 126. The data structure of the secondary authentication database 127 is assumed to be a list of records in the authentication database 126 in which the registration mark column is “Roller Coaster” (the data structure itself is Details similar to those in the authentication database 126 are omitted).

  The payment database 128 is a database that stores data on payment processing necessary for purchase and use of goods and services performed by users of commercial facilities such as the amusement park. The payment database 128 includes, for example, a collection of records associated with data such as a usage location of a service that is a payment target, a credit card number of a user used for payment, and a payment amount, using a payment time as a key. It has become.

--- Processing flow example 1 ---
Hereinafter, the actual procedure of the biometric authentication method in the present embodiment will be described with reference to the drawings. Various operations corresponding to the biometric authentication method described below are realized by a program that the system 100 reads into the memory and executes. And this program is comprised from the code | cord | chord for performing the various operation | movement demonstrated below.

  FIG. 4 is a flowchart showing a processing procedure example 1 of the biometric authentication method of the present embodiment. Here, as an example, a description will be given based on the situation where the system 100 is applied to an amusement park that requires biometric authentication of a user when using an attraction. In addition, it is assumed that the user of this amusement park is basically a member after prior membership registration, and each person has a membership card 1.

  First, at the reception terminal 300 installed at an amusement park entrance or the like, the user performs selection input as to whether or not the user is a member. At this time, the receiving terminal 300 receives the selection input and transfers it to the system 100. The target person narrowing means 110 of the system 100 receives input data of the user (authenticated person) at the input interface 105 (s100). In this case, it is assumed that the reception terminal 300 is integrated with the input interface 105 of the system 100.

  If the target person narrowing means 110 of the system 100 has acquired data indicating that the user is a member from the receiving terminal 300 (s101: Yes), the process proceeds to step s102. On the other hand, if data indicating that the user is not a member but a temporary member is acquired from the reception terminal 300 (s101: No), the process proceeds to step s110.

  When the user is a member (s101: Yes), the target person narrowing means 110 of the system 100, for example, “Hold the member card 1 over the IC card reader or enter the member number”. The message is returned to the reception terminal 300 (s102) and displayed on the display of the reception terminal 300. In response to the message, for example, the user performs an operation of holding the member card 1 possessed by the user over the IC card reader 150 (s103: card). On the other hand, the IC card reader 150 executes a reading process for the user's membership card 1 and acquires data stored in the IC chip 10 of the membership card 1. In this case, the authentication data specifying means 111 of the system 100 reads the data read from the IC chip 10 from the IC card reader 150 (for example, member number, name, credit card No, registration mark, finger vein template 1, finger vein template 1, 2) is acquired and stored in the authentication database 126 (s104).

  On the other hand, it is assumed that the user inputs his / her member number at the receiving terminal 300 in response to the message (s103: number). At this time, the receiving terminal 300 receives the input of the member number, and transmits the member number data to the system 100. On the other hand, the target person narrowing means 110 of the system 100 acquires the member number data from the receiving terminal 300 and collates it with the member number (attribute) of each biometric information registrant in the member database 125. The matching biometric information registrant is specified as the person to be authenticated (s105).

  Then, the authentication data specifying means 111 of the system 100 specifies the biometric information of the biometric information registrant corresponding to the authentication subject in the member database 125, and the data of the specified biometric information group specified here is the authentication. (S106).

  On the other hand, when the target person narrowing means 110 of the system 100 acquires data indicating that the user is not a member but a temporary member from the reception terminal 300 (s101: No), A message requesting input of user information such as the user's name is transmitted. Then, the user information input by the user is acquired from the reception terminal 300 (s110). Further, the target person narrowing means 110 of the system 100 instructs the IC card reader 150 to execute the reading process for the credit card possessed by the user, for example, and the credit card No. data is read from the IC card reader 150. Obtain (s111). Furthermore, the target person narrowing means 110 of the system 100 instructs the reading device 200 in the reception facility to read the user's biometric information, for example, and the user's biometric information is read from the reading device 200. Data is acquired (s112). In this way, the target person narrowing means 110 of the system 100 acquires user information such as name, credit card No. for payment, and biometric information for biometric authentication for the user who is a temporary member, and uses this for the authentication database. 126 (s113). In the example of FIG. 2 (b), the record set is made of a "provisional registration" is registered in the name field.

  After the above processing, it is assumed that the user wants to use the attraction in the amusement park, and a situation has occurred in which the reading device 200 for the attraction has read biological information. In this case, the authentication execution means 112 of the system 100 acquires the read biometric information read by the reader 200 from the reader 200 (s120). Then, the read biometric information is collated with the biometric information group of the authentication database 126 (s121), and if the biometric information matching the read biometric information exists in the biometric information group, the authentication is successful (s121: OK). This is notified to the output means 113. In addition, data such as an attraction ID, a usage time, and a credit card number of the attraction use applicant are stored in the settlement database 128 as settlement data for the attraction use price used by the attraction use applicant with the success of authentication. Keep it. On the other hand, the output means 113 of the system 100 outputs the successful authentication data to the output interface of the attraction reader 200 (122).

  On the other hand, when the biometric information that matches the read biometric information does not exist in the biometric information group, the authentication execution unit 112 determines that authentication is unsuccessful (s121: NG), and is registered in the read biometric information and the member database 125. The biometric information is collated (s123). If biometric information matching the read biometric information is found in this collation process, authentication is successful (s123: OK), the output means 113 is notified to that effect, and the settlement data is stored in the settlement database 128. . On the other hand, if the matching biometric information is not detected even in the collation (s123: NG), the attraction use applicant (authenticated person) notifies the output means 113 that the use of the attraction is not permitted as authentication NG. Notification is made (s124). The output means 113, to the reading device 200, and outputs the data of the authentication unsuccessful (s125), and ends the process.

--- Processing flow example 2 ---
In the above processing flow example 1, an example is shown in which the authentication database 126 is formed for all members who have entered the amusement park, and is used during biometric authentication. Furthermore, as an example of improving the biometric authentication process, an example using a registration mark is shown below.

  FIG. 5 is a flowchart illustrating a processing procedure example 2 of the biometric authentication method according to the embodiment. In this case, the secondary authentication data specifying unit 114 of the system 100 is configured such that after the authentication database 126 for the visitors (same as the authentication database in the processing flow example 1) is stored in the storage unit 101, In the reception terminal 250 installed in the attraction, a designation of a registration mark, for example, “a roller coaster” is received from an authenticated person who wishes to use the attraction (s200). Then, the registration mark “roller coaster” received here is collated with each biometric information group data in the authentication database 126 for the visitor, and the biometric information of the biometric information registrant with the matching mark is extracted. The data is stored in the authentication database 127 (see FIG. 3A) (s201).

  Therefore, the each biometric information registration's record in the member database 125, it is assumed that the set of the registration mark when registering the biometric information. Details of this setting processing will be described in another processing flow example.

  Further, the secondary authentication execution means 115 acquires the read biometric information read by the attraction reader 200 from the reader 200 from the attraction use applicant, and the read biometric information is used for the secondary authentication. The biometric information group in the database 127 is collated (s202). If biometric information that matches the read biometric information exists in the biometric information group, authentication is successful (s202: OK), and that effect is notified to the output means 113 (s203). Upon receiving this, the output means 113 outputs the attraction use permission notification to the display of the attraction accepting terminal 250 (s204).

  On the other hand, when the biometric information that matches the read biometric information does not exist in the biometric information group, the secondary authentication execution unit 115 determines that authentication is unsuccessful (s202: NG), and notifies the output unit 113 of this fact ( s205). Receiving this, the output means 113 outputs the attraction use disapproval notice to the display of the previous attraction accepting terminal 250 (s206).

  If the attraction use person remembers the wrong registration mark, the registration mark designation itself accepted by the system 100 in step s200 is incorrect. Then, the biometric information extracted in the subsequent step s201 also becomes biometric information of a person for whom a mark different from the attraction use desirer is set. Therefore, even if the attraction use applicant is a legitimate user who has registered biometric information in the authentication database 126 in advance, the verification of the read biometric information in the step s202 and the secondary authentication database 127 is performed. If you do, authentication will be unsuccessful. Therefore, when the authentication is unsuccessful (s202: NG) in order to rescue the attraction use candidate placed in such a situation, the system 100 uses the read biometric information for authentication as an example of another pattern flow. The database 126 is collated (s207), and if the authentication is successful (s207: OK), the registration mark information set for the attraction user is output to the output means 113 (s208), and the attraction is used. The applicant is notified of successful authentication (s203). On the other hand, if the authentication is unsuccessful (s207: NG), the output unit 113 is notified that the authentication is unsuccessful (s205).

--- Processing flow example 3 ---
Next, registration mark setting processing will be described. FIG. 6 is a flowchart showing a processing procedure example 3 of the biometric authentication method of the present embodiment. In this case, the symbol data registration unit 116 of the system 100 accepts a registration mark setting start instruction by the biometric information registrant at the input interface 105 before the processing of the secondary authentication data specifying unit 114 (s300). Upon receiving this instruction, the symbol data registration means 116 counts the biometric information registered in the member database 125 to the set symbol data type (s301), and the symbols are arranged in the order in which the number of biometric information is far from the predetermined reference number. A list specifying the data type is generated (s302). For example, “1800” pieces of biometric information set with a “roller coaster” mark, “1000” pieces of biometric information set with a “ferris wheel” mark, and biometric information set with a “merry-go-round” mark Is counted as “500”, and the predetermined reference number is “1800”, the biological information number is in the order farthest from the predetermined reference number, that is, “merry-go-round”, “ferris wheel”, “roller coaster” The list is generated by specifying the mark type in order.

  Then, the symbol data registration unit 116 displays information on registered marks of a predetermined rank or higher in the list on the output interface 106 as selectable marks (s303). Since the predetermined reference number is “1800” and the biometric information set with the “Roller coaster” mark is “1800”, the “Roller coaster” mark has already reached the standard. if performing the process of excluding from in the list, it is preferable in the sense to reduce the setting biometric information number of balance between marks.

  Subsequently, the symbol data registration unit 116 accepts an instruction to select a registration mark from the list in the input interface 105 by the biometric information registrant (s304). Then, the symbol data information corresponding to the selection instruction is stored in the member database 125 in association with the biometric information of the biometric information registrant (s305).

--- Processing flow example 4 ---
In the processing flow example 3 described above, the registration mark selection is received from the user and the setting process is performed. However, in addition to this, a case where the registration mark setting process is automatically performed on the system side can be assumed.

  FIG. 7 is a flowchart showing a processing procedure example 4 of the biometric authentication method of the present embodiment. At this time, the registration mark is determined for each biometric information group obtained by dividing biometric information registered in the member database 125 every predetermined number (for example, every 2000 people), and the biometric information to which the biometric information belongs. It can be assumed that the information registrant is set in the member database 125. The biometric information registrant belongs to which biometric information group. For example, if the biometric information group is divided in the order of biometric information registration, the biometric information registrant belongs to the final group at the time of registration processing. I can assume the situation.

  In such a situation, the symbol data setting means 117 of the system 100 counts a predetermined number of biometric information registered in the member database 125 when registering the biometric information of a biometric information registrant X in the member database 125. A biometric information group is set for each (s400). For example, it is assumed that biometric information groups A to C are generated for every 2000 people in the order of biometric information registration. The biometric information groups A and B belong to 2000 biometric information registrants, while the biometric information group C has not reached 2000 yet.

  Further, the symbol data registration unit 116 specifies that the biometric information group to which the biometric information registrant X belongs is the biometric information group C whose registration date and time does not reach the predetermined number at the end, and is specified here. The registration mark (for example, “Ferris wheel”) information corresponding to the biometric information group C is stored in association with the biometric information registered in the member database 125 (s401).

  At this time, the symbol data notifying unit 118 of the system 100 displays information on the registration mark “Ferris wheel” corresponding to the biometric information group C to which the registered biometric information belongs on the output interface 106, and the biometric information is displayed. The registrant X is notified (s402).

--- Processing flow example 5 ---
A user who enters the amusement park and uses the attraction leaves the amusement park at the closing time or at his own time.

  FIG. 8 is a flowchart showing a processing procedure example 5 of the biometric authentication method of the present embodiment. In this case, the first deletion unit 119 of the system 100 detects, for example, the arrival of the closing time by the clock function 130 (eg, the closing time is preset in the clock function 130 as a timer time), and the closing time arrives. when it is detected (s500: Yes), it deletes the authentication database 126 stored in the storage unit 101 (s501).

  On the other hand, when the arrival of the closing time has not been detected (s500: No), the second deletion means 120 of the system 100 determines the predetermined attribute by the person to be authenticated at the input interface 105 (and the reception terminal 300 connected thereto). When detection of input of data (e.g., logoff data or exit notification data) is executed (s502), and input of the predetermined attribute data by the person to be authenticated is detected (s502: Yes), the living body of the person to be authenticated For example, the information is specified from the authentication database 126 using “member No.” included in the logoff data as the predetermined attribute data as a key and deleted (s503).

--- Processing flow example 6 ---
In addition to the above-described biometric authentication process when using an attraction, a situation where the system 100 according to the present embodiment executes a biometric authentication process when using a locker installed in an amusement park can be assumed.

  FIG. 9 is a flowchart showing a processing procedure example 6 of the biometric authentication method of the present embodiment. In this case, the secondary authentication data specifying unit 114 of the system 100 is configured such that after the authentication database 126 for the visitors (same as the authentication database in the processing flow example 1) is stored in the storage unit 101, The reception terminal 250 installed in the locker receives a designation of a registration mark, for example, a “roller coaster” from the person who wishes to use the locker (s600). Then, the registration mark “roller coaster” received here is collated with each biometric information group data in the authentication database 126 for the visitor, and the biometric information of the biometric information registrant with the matching mark is extracted. The data is stored in the authentication database 127 (see FIG. 3A) (s601).

  Furthermore, the secondary authentication execution means 115 acquires the read biometric information read by the locker reader 200 from the reader 200 from the locker user, and uses the read biometric information for the secondary authentication. It collates with the biological information group of the database 127 (s602). If biometric information that matches the read biometric information exists in the biometric information group, authentication is successful (s602: OK), the fact is notified to the reception terminal 250, and the locker at the reception terminal 250 is notified. The number input data of the desired locker from the user who wants to use is acquired (s603).

  If the desired locker is in use (s604: Yes), the secondary authentication execution means 115 returns the process to step s603 to accept the number input of another desired locker. On the other hand, if the desired locker is not in use (s604: No), the corresponding locker number is set in the secondary authentication database 127 (s605). The locker installed in the amusement park is an electronic locker whose use / non-use is monitored by the system 100 and the locking / unlocking is controlled, for example. Assume that you are managing data on locker usage and locking status.

  Further, the secondary authentication execution means 115 notifies the locker of a lock instruction to the desired locker after a predetermined time or upon receiving a notification of the completion of the storage of the package through the locker interface (s606). On the other hand, when unlocking the locked locker in this way, the biometric authentication process from the above steps s600 to s602 is executed in the same manner for the user who wishes to unlock the locker. Will be notified of the unlocking instruction.

--- Processing flow example 7 ---
In addition to the above-described biometric authentication process when using an attraction or locker, the system 100 according to the present embodiment executes a biometric authentication process when using a guest room of an accommodation facility such as a hotel attached to the amusement park. Can also be assumed.

  FIG. 10 is a flowchart showing a processing procedure example 7 of the biometric authentication method of this embodiment. In this case, the secondary authentication data specifying unit 114 of the system 100 is configured such that after the authentication database 126 for the visitors (same as the authentication database in the processing flow example 1) is stored in the storage unit 101, A room number is designated for a person who wishes to use the guest room at the reception terminal 250 installed at the front of the hotel, and the designated room number is stored in the authentication database 126 for the visitor. It sets with respect to a corresponding biometric information registrant (s700).

  Still further, the secondary authentication execution means 115 receives the room number or the guest room notification data input by the room use applicant through the reception terminal 250 installed at the entrance of the guest room. The biometric information is extracted from the authentication database 126 using as a key (s701). Subsequently, the secondary authentication execution unit 115 acquires the read biometric information read from the passenger who desires to use the cabin by the reader 200 installed at the entrance of the cabin from the reader 200, and the read biometric information is obtained from the reader 200. The biometric information extracted from the authentication database 126 is collated (s702).

  When the read biometric information matches the biometric information extracted from the authentication database 126, authentication is successful (s702: OK), and an unlocking instruction is notified to the locking device of the passenger door (s703). The locking device installed in the hotel guest room door is, for example, an electronic key whose locking / unlocking is network-monitored by the system 100 and the locking / unlocking is controlled. Assume that data management of the locking status of each cabin door is performed in 101.

--- Other examples ---
As another embodiment, each user who entered the amusement park has designated in advance a mark corresponding to the attraction to be used, and for each piece of biometric information in which the corresponding mark is set in each attraction. However, a processing mode in which only biometric authentication is performed can be assumed. That is, such an example of processing can also be applied to the case where the attractions used by each user are fixed in advance.

  In some cases, such as when an amusement park and a hotel are installed, it may be necessary to perform biometric authentication processing across multiple facilities. In this case, for example, when a certain user A leaves the amusement park and does not use the hotel, the authentication database 126 generated at the amusement park is taken over for biometric authentication processing at the hotel. For this reason, the system 100 to divert the authentication database 126 generated by the amusement park as the authentication database 126 at the hotel. Alternatively, when the entrance process is performed in either the amusement park or the hotel, it is possible to generate the authentication database 126 for both of them and to assume that both have entered. Still further, in the authentication database 126 and the secondary authentication database 127, the expiration date (for example, data corresponding to the contents of the member contract of the corresponding user and the nature of the purchased ticket, necessary data from the member contract system, the ticket sales system, etc.) The system 100 may obtain a field), and when using such a plurality of facilities, the biometric authentication process may be executed only within the expiration date.

  Thus, according to the present embodiment, the biometric authentication process can be executed at high speed in a situation where a large number of templates are registered.

  As mentioned above, although embodiment of this invention was described concretely based on the embodiment, it is not limited to this and can be variously changed in the range which does not deviate from the summary.
