TECHNICAL FIELD OF THE INVENTION
The present invention relates to a user authentication method and system for performing user authentication using biometric information.
[0002]
[Prior art]
Conventionally, for example, at a bank counter, by imprinting the same seal as the bank report stamp stamped on the bank passbook, it has been recognized that the passbook owner is the person who owns the passbook, and transactions such as withdrawal of deposits have been possible. In many cases, an insurance card alone can be used as proof of identity just by owning the insurance card.
[0003]
In addition, conventionally, there is a method in which the matching between registered seal imprint data of a bank report and verified seal imprint data, which is an imprint of a seal brought by a customer, is repeated by shifting the overlapping position of these imprints. (For example, see Patent Document 1).

[0025]
<motion>
Hereinafter, the user authentication method of the specific example 1 will be described with reference to the flowchart of FIG.
Here, in the following operation, a description will be given assuming that the biometric information recording medium 300 is a biometric information recording sticker that can be attached to an arbitrary target.
First, the operation of the biometric information recording device 100 (Steps S11 to S14) will be described.
First, the biometric information recording device 100 captures an eye of a user with the camera 101 and acquires an eye image (step S11). Next, the iris code generation unit 104 generates an iris code from the eye image data (Step S12). This iris code is data having a value unique to the target user. Since the process of generating the iris code from the user's eye image is known, the description is omitted here. Next, the iris code conversion unit 105 converts the iris code into, for example, data expressed by numerical values and outputs the data as bar code data (step S13). Here, the iris code conversion unit 105 may perform processing such as encryption in order to print a raw iris code and prevent personal information from being stolen. Next, the biometric data recording unit 103 prints the biometric information recording medium 300 as an authentication barcode on the basis of the barcode data output from the iris code conversion unit 105 (step S14). The biometric information recording sticker on which the authentication barcode is printed, which is the biometric information recording medium 300, is used by attaching it to an object to be authenticated such as a passbook as described later. In FIGS. 1 and 2, the authentication barcode is in the form of a one-dimensional barcode, but may be printed as a number or a two-dimensional barcode.
[0026]
Next, the operation of the user authentication device 200 (steps S21a, 21b to step S23) will be described.
When the biometric information recording medium 300 possessed by the user is given, the user authentication device 200 reads the authentication barcode of the biometric information recording medium 300 by the authentication barcode reading unit 204 (Step S21a). Further, the user's eyes are photographed by the camera 206, and an eye image is obtained (step S21b). Next, the authentication barcode conversion unit 205 restores the iris code data from the barcode data read by the authentication barcode reading unit 204 (Step S22a). Here, if the authentication barcode is encrypted, the iris code is restored after decryption. In addition, the iris code generation unit 207 generates an iris code from the eye image captured by the camera 206 (Step S22b). That is, the processing from step S21b to step S22b is the same as the processing from step S11 to step S12. The user authentication unit 203 compares the iris code output from the authentication barcode conversion unit 205 and the iris code output from the iris code generation unit 207, that is, the iris data recorded on the biometric information recording medium 300. Then, it is compared with the iris data acquired from the user, and it is determined whether the user is a valid user of the biometric information recording medium 300 (step S23). If the iris codes match in this step S23, it is determined that the user is a valid user, and the result of collation OK is output.
[0027]
Next, an example in which the user authentication system is applied to a bank or a post office will be described. That is, in this case, the biological information recording medium 300 corresponds to a passbook.
FIG. 3 is a diagram illustrating the operation when a passbook is issued and when the passbook is used.
When issuing a passbook at the branch A, first, a general passbook in which information such as a customer name and an account number is described is created (step S31). At this time, the biometric information recording device 100 creates an authentication barcode based on the iris data of the customer, and issues a biometric information recording sticker on which the authentication barcode is printed (step S32). Then, a biometric information recording sticker on which the authentication barcode is printed is attached to a predetermined position of the passbook (step S33).
[0028]
FIG. 4 is an explanatory diagram of the issued passbook.
As shown, a biometric information recording sticker is attached to a predetermined position 401 of a passbook 400 as a biometric information recording medium. When the iris code is encrypted, it becomes a secret key in the issuing bank or post office. Further, in order to prevent the attached biometric information recording sticker from being peeled off, a protective seal 402 is attached from above the biometric information recording sticker. The protective seal 402 has such a property that once peeled off, the peeled-off mark emerges, and is a general protective seal.
[0029]
Next, an operation when a customer who possesses such a passbook conducts a transaction using the passbook will be described.
Returning to FIG. 3, for example, it is assumed that the customer withdraws a deposit at the branch B using a passbook. In this case, the customer submits a passbook to the window (step S41), and receives an identity verification by the user authentication device 200 (step S42). That is, in step S42, the processes of steps S21a (21b) to S23 of FIG. 1 are performed. When it is confirmed that the user is the person who owns the passbook by the personal identification processing, payment of a deposit is executed (step S43). Here, the processing at the window is used as the operation when the passbook is used. However, if the automatic transaction apparatus has the function of the user authentication apparatus 200, the processing at the automatic transaction apparatus is also possible.
[0030]
<effect>
As described above, according to the specific example 1, when biometric information data of a user is recorded on the biometric information recording medium 300 in an optically readable state such as a bar code, and user authentication is performed, Since the biometric information data extracted from the recording medium 300 is compared with the biometric information data of the user to determine whether the user is a valid user, the following effects are obtained.
That is, since the relationship between the user and the biometric information recording medium 300 possessed by the user is uniquely linked, even if the biometric information recording medium 300 is forged, it does not match the biometric information of the individual, Unauthorized use of the recording medium 300 due to forgery or the like can be prevented.
[0031]
Further, in the specific example 1, since the biometric information recording medium 300 is configured by the biometric information recording sticker, any object can be used as an object to be authenticated by attaching the biometric information recording sticker. As a result, the use range of the user authentication can be expanded. For example, the present invention can be applied to various usages, such as a user holding a plurality of such biometric information recording stickers and attaching the sticker to each object requiring identification.
In addition, since user authentication can be performed only by the biometric information recording medium 300 and the user, no separate biometric information is required for the authentication process. Therefore, a configuration in which the system side does not store the biometric information is also possible. With such a configuration, the storage side can be reduced on the system side, and the personal information can be misused for the user. Since there is no fear, there is an effect that it can be used easily.
Further, in the above specific example 1, the biometric information recording medium 300 is configured by affixing the biometric information recording sticker to the object to be authenticated, but a configuration in which the biometric information recording medium is directly printed on the object to be authenticated may be employed.
[0032]
<< Specific Example 2 >>
Example 2 is a user authentication system in which the biometric information recording medium 300 is used as a ticket and the ticket can be reissued.
[0033]
<Constitution>

The user authentication device 600 is a device that authenticates a user from a ticket provided with a barcode based on an iris pattern, and is, for example, a device installed at a place such as a venue entrance of an event using the ticket. is there.
[0034]
The ticket issuing device 500 includes a camera 501, a control unit 502, and a customer information database 503. A camera 501 is an imaging unit that captures an iris image of a user, and has the same function as the cameras 101 and 206 in the first embodiment.
[0035]
The control unit 502 is a functional unit that issues tickets and registers customer information in the ticket issuing device 500, and includes a ticket issuing unit 504, a customer information registration unit 505, and a reissue processing unit 506. The ticket issuing unit 504 has a function of issuing a predetermined ticket, and has a function of the biological information data conversion unit 102 and the biological information data recording unit 103 in the first embodiment. That is, the ticket issuing unit 504 has a function of issuing a ticket and performing processing such as iris code generation, iris code conversion, and barcode printing from an eye image of a customer (user of the ticket). In addition, the ticket issuing unit 504 has a function of accepting input of personal information such as a customer's address and name when a ticket is issued.
[0036]
The customer information registration unit 505 is a functional unit that, when the ticket issuing unit 504 issues a ticket, associates the ticket information with personal information including the iris code of the customer and stores the information in the customer information database 503. Note that the ticket information may be a serial number assigned to each ticket, or may simply store the type of ticket.
[0037]
The reissue processing unit 506 generates an iris code from an eye image of the customer when an arbitrary customer requests a ticket reissue due to loss of the ticket or the like, and stores the iris code stored in the customer information database 503. Has a function of reissuing the ticket associated with the iris code when there is a matching iris code. That is, the reissue processing unit 506 has the functions of the biometric information data conversion unit 102 and the biometric information data recording unit 103 and the search function in the customer information database 503 in the first embodiment.
[0038]
The customer information database 503 is a database for storing personal information such as the name and address of the customer and biometric information such as iris code data of the customer and data of the issued ticket as data, and is a storage device such as a hard disk device. It consists of The customer information database 503 is prepared for each ticket counter, but is connected via a network so that it can be searched from other ticket counters.
The control unit 502 includes a personal computer or the like. Each function of the ticket issuing unit 504 to the reissue processing unit 506 includes software corresponding to each function and hardware such as a CPU and a memory that execute the software. Has been realized.
Note that the ticket issuing device 500 is actually realized by adding an iris authentication device to a conventional ticket issuing device.
[0039]
The user authentication device 600 includes a biometric information data generation unit 601, a biometric information data acquisition unit 602, and a user authentication unit 603. These configurations are the same as those of the biometric information data generation unit 201 to the user authentication unit 203 in the first embodiment, and a description thereof will be omitted.
[0040]
<motion>
Hereinafter, the operation of the user authentication system having the above configuration will be described.
FIG. 6 is an operation flowchart when the ticket issuance device 500 issues a ticket.
First, the ticket issuing unit 504 of the ticket issuing device 500 issues a normal ticket (a ticket without an authentication barcode) (step S101). Next, the ticket issuing unit 504 generates an iris code of the user (step S102). That is, step S102 is the same as the processing of steps S11 and S12 in the first specific example. Further, the customer information registration unit 505 registers the generated iris code in the customer information database 503 together with the personal information of the user (step S103). The iris code on the customer information database 503 is stored until the event date, and is deleted by the customer information registration unit 505 at the end of the event. Next, the ticket issuing unit 504 converts the generated iris code into an authentication barcode, and prints out this (step S104). Then, the printed authentication barcode is attached to the ticket issued in step S101 and provided to the user. Note that the process of attaching the authentication barcode may be performed by a ticket counter staff or automatically by the ticket issuing device 500. Also, instead of separately issuing the ticket and issuing the authentication barcode as described above, the authentication barcode may be printed and output directly on the ticket.
[0041]
Next, an operation performed when a ticket reissue request is received from a user will be described.
FIG. 7 is an operation flowchart when a ticket is reissued.
When a user wants to reissue a ticket due to a lost ticket or the like, the user goes to a ticket counter and presents or fills out a predetermined form with personal information registered at the time of issuing the ticket and submits it. In response, the reissue processing unit 506 of the ticket issuing device 500 searches the customer information database 503 for an iris code corresponding to the input personal information of the user (step S201). Here, since the customer information database 503 is connected to the plurality of ticket counters so as to be searchable on the network, the ticket counter receiving the reissue request is different from the store of the ticket counter that originally issued the ticket. You may. Next, the reissue processing unit 506 recognizes the user's iris using the iris code registered by the user as dictionary data (step S202). If the user is correctly authenticated by the iris recognition, a ticket and an authentication barcode similar to the ticket purchased first by the user are reissued (steps S203 and S204), and the authentication barcode is attached to the reissued ticket. (Step S205). In this case, the authentication barcode may be directly printed on the ticket. When reissuing a ticket, a reissuing fee of, for example, several percent of the ticket price may be paid.
[0042]
Next, the procedure at the event venue will be described.
In this case, the operation is performed in the same manner as the operations of steps S21a (S21b) to S23 of the first specific example described with reference to FIG. That is, the authentication barcode attached to the user's ticket is read by the user authentication device 600 installed at the entrance of the event venue, and an iris code is generated from the authentication barcode data. In addition, the image of the user is photographed, and an iris code is generated from the eye image. Then, iris recognition of the iris code of the user is performed by using the iris code converted from the authentication bar code as dictionary data, and identification is performed. Then, if the user is confirmed to be a valid user of the ticket presented by the identity verification, entry to the event venue becomes possible.
[0043]
<effect>
As described above, in the specific example 2, the biometric information is recorded in the ticket, the biometric information is held in association with the ticket, and when a ticket reissue request is made, the biometric information is re-created based on the stored information. Since the issuance is performed, the following effects are obtained.
That is, since the biometric information of the user is recorded in the ticket, only the purchaser of the ticket can use the ticket. Therefore, it is possible to prevent improper use of the ticket due to forgery of the ticket and use of the ticket obtained illegally.
In addition, even if the user has lost or stolen the ticket, the ticket can be reissued. In this case, when entering the event, only the person who presented the ticket can enter, so even if the user owns the illegally reissued ticket, the ticket can be used by other people It is impossible to do. Therefore, it is possible to prevent an act of illegally reissuing and reselling the ticket.
From such a point, the specific example 2 has a particularly great effect for an event or the like that requires extremely high security at the time of entry.
[0044]
《Usage form》
In each of the above specific examples, the biometric information is formed into a sticker and affixed to a passbook or a ticket. However, the present invention is not limited to this. For example, the biometric information may be shaped like a tag attached to baggage.
Further, in the specific example 2, the example in which the ticket is used at the time of entering the event has been described. However, the ticket may be used at the time of re-entering the event site. That is, when the user once leaves the event venue, he or she leaves with the ticket used at the time of entry. Then, by performing the same personal identification processing as that at the time of the first entry at the time of re-entry, there is an effect that no separate means is required at the time of the event re-entry. This is very effective for entering and re-entering an event or a theme park or the like over a plurality of days.
[0045]
In the above specific example 2, a predetermined period is set as a period to be stored in the customer information database 503, such as up to the event date, but if a form such as member registration is provided for the ticket issuer, The storage of the biometric information may be continued for the user who wants to register. With this configuration, when the next event is held, the biological information stored in the customer information database 503 can be used as it is. Therefore, it is not necessary to perform an iris image acquisition process every time a ticket is issued, and the burden on both the ticket issuing side and the user side can be reduced. In addition, when admission is possible throughout the year, such as in a theme park, a user who is allowed to register biometric information may be stored for a specific period, such as one year. Also in this case, if it is within the period, the work of registering the biometric information at the time of entry can be unnecessary.
[0046]
In the above specific example 2, in order to reissue a ticket, the biometric information of the ticket purchaser is stored in the customer information database 503 or the like. However, if only the ticket user confirmation is performed, the ticket purchaser It is also possible not to save the biological information of the user. That is, by providing the purchaser's biometric information to the ticket when the ticket is issued, the ticket is associated with the purchaser, so that it is not necessary to store biometric information data as a user authentication system. With such a configuration, it is possible to reduce the storage area on the system side and to simplify the configuration, and it is also possible for a user who feels reluctant to register his / her biometric information with the ticket issuer. , Such a feeling of resistance can be reduced.
Further, in the above-described specific example 2, a selection unit for determining whether or not the ticket can be reissued to the user may be provided. That is, in the ticket counter, it is confirmed whether the ticket is reissueable to the customer, and the ticket issuance processing for recording the biometric information is performed only for the customer who wants to purchase the reissueable ticket. You may. With this configuration, even a customer who has a resistance to disclosing his / her biometric information to the ticket issuer can purchase the ticket. In addition, one customer can purchase a plurality of tickets, such as a ticket whose ticket can be reissued and a ticket whose ticket cannot be reissued. In such a configuration, a ticket for performing user authentication and a ticket for which user authentication is not performed (cannot be performed) are mixed at the time of entering the event, but a ticket for performing user authentication (recording biometric information) A privilege may be provided to the user who owns the ticket), such as giving priority to entry.
Further, in the case of a configuration in which the user's biometric information is not stored in the above-described system, a selection unit for determining whether or not to use the biometric information recorded ticket may be provided. In such a case, the biometric information is recorded. A privilege may be provided such that a user having a ticket that has entered can enter the event preferentially when entering the event.
[0047]
Further, in each of the above specific examples, all data of the user's biometric information is recorded on the biometric information recording medium 300, but it may be configured to record only a part of the biometric information. For example, when only the first half of the iris code is recorded and user authentication is performed, comparison is made with the data of the first half of the iris code obtained from the user. As another configuration, only the first half of the iris code is recorded on the biological information recording medium 300, and the second half is stored on the system side. At the time of user authentication, the first iris code obtained from the biometric information recording medium 300 and the second iris code stored in the system are combined to create an iris code for one person, and this iris code is obtained. The comparison may be performed by comparing the user's iris code with the user's iris code. However, in this case, it is necessary to record on the biometric information recording medium 300 information indicating which biometric information stored in the system corresponding to the partial biometric information to be recorded on the biometric information recording medium 300. Further, it is necessary that the user authentication device, the storage unit for the biometric information on the system side, and the network be accessible.
[0048]
As described above, if the biometric information data to be recorded on the biometric information recording medium 300 is partial, it becomes difficult to restore the biometric information of the user from the recorded biometric information data. The safety as 300 can be further improved. Even when the system is configured to store the latter half of the iris code, not all of the user's biometric information is registered, so the user's own biometric information must be registered with the ticket issuer. Such a feeling of resistance can be reduced even for a user who feels resistance.

【The invention's effect】
As described above, according to the present invention, biometric information data of a user is recorded in a biometric information recording medium in an optically readable state, and when performing user authentication, biometric information data extracted from the user. And the biometric information data read from the biometric information recording medium, and if they match, it is determined that the user is a valid user of the biometric information recording medium.
That is, since the relationship between the user and the biometric information recording medium possessed by the user is uniquely linked, it is possible to prevent improper use of the biometric information recording medium due to forgery, etc. Use of a biological information recording medium other than the person can also be prevented.
