[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a biometric information authentication system, an authentication token, and an authentication method for providing a service to a user by proving whether or not the user is the identity of the user when the user receives a certain service, using the biometric information of the user.
[0002]
[Prior art]
2. Description of the Related Art Among devices such as a PC (personal computer) and a mobile phone, there is a device having an authentication function of proving that a user is himself using biometric information of a user and providing various services to the user. FIG. 8 is a diagram showing an example of a system having such an authentication function. A sensor unit 10A in which a sensor 11 for reading biometric information of a user is mounted on a use device 30 which is a service providing device such as a PC or a mobile phone. And a processing device 31 such as a processor or a microcomputer mounted in the utilization device 30 authenticates whether or not the user is himself based on the sensing data E read by the sensor unit 10A, and , The service is provided to the user.
[0003]
As another example of a system having this type of authentication function, as shown in FIG. 9, an authentication device (authentication token 10) possessed by a user is connected to a use device 30 to which a user is provided with a service. A system has been proposed in which a user is authenticated using biometric information in the authentication device, and the result of the authentication is transmitted to the use device 30. In this authentication system, user registration information is stored in an authentication device possessed by each user, and the steps from reading biometric information to collation are performed in this authentication device. Only the authentication result (communication data H) obtained by this collation is transmitted to the use device 30, and the use device 30 provides a service based on this information.
[0004]
[Problems to be solved by the invention]
In the authentication system shown in FIG. 8, since the verification of the biometric information of the user is performed by the processing device 31 in the device 30, the authentication software O and the registration data D of the user are installed in the storage circuit 32 in the device 30. There must be. However, among devices already used in large quantities, such as PCs and mobile phones, many devices do not have such authentication software O and registration data D, so that an authentication system based on biometric information can be introduced. It is necessary to install authentication software and registration data on such devices in advance, which is a hindrance to the introduction of this type of authentication system.
[0005]
On the other hand, in the authentication system shown in FIG. 9, since the biometric information is collated by the authentication device possessed by the user, the collation software and the registered data of the user do not need to be mounted on the device 30. However, the authentication device receives the communication data H (authentication result) indicating whether or not the user is the user, and determines whether the communication data H is legitimate data. Then, the dedicated software for the authentication device for starting the provision of the service is installed in the use device 30 in advance, or the service providing software A installed in the use device 30 is operated by the communication data H from the authentication device. Must be changed to In this case, as in the conventional example shown in FIG. 8, the authentication device software must be installed in advance on all the devices used by the user, which makes it difficult to introduce an authentication system.
[0006]
The present invention has been made in view of such a problem, and an object of the present invention is to provide authentication based on biometric information without installing dedicated software on a general device already used by a user. The purpose is to enable the system to be introduced.

[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing the configuration of the biometric information authentication system according to the present invention. As shown in FIG. 1, the biometric information authentication system includes a use device 30 that provides a service to a user and an authentication token 10 possessed by the user.
[0012]
The authentication token 10 includes a sensor 11 for reading biometric information, a registration memory 13 for storing registered biometric information data (registration data D) of a possessing user, a user memory 15 for storing user information, and a sensor 11. The matching circuit 12 compares and compares the biometric information data (sensing data E) read in step 1 with the registered biometric information data stored in the registration memory 13, and the user information (user information C) output from the user memory 15 is compared with the matching circuit. The keyboard emulator 14 converts the collation data F into a keystroke signal J of the keyboard based on the twelve collation data F. And a communication circuit 16 for outputting the registered user information B to the user memory 15 when receiving the same. It has been.
[0013]
The present authentication system is a system that can assign a plurality of pieces of user information that can be identified by an index to one piece of registered biometric information. For this reason, in the authentication token 10, the communication circuit 16 outputs the registration index information G together with the above-mentioned registration user information B to the user memory 15 to register these pieces of information in the user memory 15 as a pair. 17, the value of the index counter 17 is increased by an index addition signal K output when the matching circuit 12 determines that the matched biometric information is the index-corresponding registered biometric information as a result of the biometric information collation. It is sent to the user memory 15 as index information I. The user memory 15 outputs user information specified by the index information I and the collation data F to the keyboard emulator 14.
[0014]
On the other hand, the use device 30 is a device such as a PC or a mobile phone, and includes a communication circuit 33 that receives communication data H indicating user information from the authentication token 10, and a user based on the user information received by the communication circuit 33. A processing device 31 that provides a service, and a storage circuit 32 that stores service software A corresponding to the provided service executed by the processing device 31.
[0015]
Here, the user stores his / her registered biometric data and user information such as a password for using the service in the authentication token 10 owned by the user in advance. Next, when using the use device 30, the user connects his / her own authentication token 10 directly or indirectly via radio waves or infrared rays to the use device 30, and causes the sensor 11 to read his / her biometric information. The matching circuit 12 performs matching between the registered biometric information data D registered in the registration memory 13 in advance and the biometric information data (sensing data E) read by the sensor 11, and when the matching results match, indicating successful matching. Output to the keyboard emulator 14 and the user memory 15 as collation data F. When the result of the collation is the registered biometric information corresponding to the index, the index addition signal K is output to the index counter 17 to increase the value of the index counter 17 as described above.
[0016]
Here, the keyboard emulator 14 outputs user information such as a password output from the user memory 15 based on the matching data F indicating the biometric information matched by the matching circuit 12 and the index information I indicating the value of the index counter 17. C (user-specific information including identification information for identifying the user) is converted into a keystroke signal J of a keyboard, and transmitted as communication data H to the device 30 through the communication circuit 16.
[0017]
The communication circuit 33 of the device 30 is a general-purpose connector and communication circuit for connecting a keyboard such as a USB, serial, wireless, or infrared ray. The communication circuit 33 transmits a keystroke signal J from the authentication token 10 connected to the communication circuit 33. , Is interpreted in the same way as a keystroke signal transmitted from the keyboard to which it is originally connected, and transmitted to the processing device 31. The processing device 31 interprets a signal transmitted from the communication circuit 33 as a signal from a keyboard, and performs a process corresponding to a key input.
[0018]
Here, when the state of the used device 30 is an input receiving state such as a password for providing a service and the keying signal J transmitted from the authentication token 10 is a password corresponding to this user, The processing device 31 interprets that the password has been input from an externally connected keyboard, and the processing device 31 executes the service software A in the storage circuit 32, thereby rewriting the input password with the password input by the user using the keyboard. In the same manner as in the case of (1), if the authentication is correct, the service is provided to the user by executing the service software A.
[0019]
As described above, in the present authentication system, the signal from the authentication token 10 is exactly the same as the password actually input by the user using the keyboard. Therefore, the processing device 31 performs the user authentication by the same processing as the conventional password verification. It is possible to do. Therefore, there is no need to install dedicated software for the authentication token in the used device 30, and it is not necessary to improve the service program (service software A) of the used device 30 for the authentication token. That is, it is possible to easily introduce an authentication system based on biometric information into a conventional authentication system using a password without newly installing or changing software or the like.
[0020]
In addition, by transmitting not only the password but also the user ID as the user information, it is possible to save the trouble of keyboard input at the time of user authentication and to enhance the convenience. Further, since the authentication token 10 automatically transmits the user ID and the password, the user does not need to store such information, and the convenience can be further improved. At the same time, it is also possible to set individually for each service while frequently updating a meaningless long password that is impossible for the user to memorize. Can be resolved into a character string having a meaning that can be easily remembered, and one password is shared for various services without updating, so that a system with higher security can be constructed.
[0021]
The new registration of the user information and the index in the authentication token 10 and the correction and addition of the user information and the index registered in the authentication token 10 are performed by the user device B equipped with the dedicated software and the registration user information B and the registration information. This can be performed by transmitting the index information G to the authentication token 10. In this case, upon receiving the registration user information B and the registration index information G, the authentication token 10 registers the user information in the user memory 15 based on the received registration user information B and the registration index information G. And correction of user information in the user memory 15 and the like.
[0022]
For such processing, a user device equipped with dedicated software is required, but such processing is not always performed, but only when changing user information. What is necessary is just to connect to the available utilization equipment. Since this processing is very rare compared to the authentication processing at the time of providing a normal service, the convenience of the user is hardly impaired. In addition, as for the service for the registration processing of the user information and the index information, the user information and the index information are not arbitrarily rewritten by introducing the user authentication based on the biometric information using the authentication token 10, but the dedicated use device is used. Thus, a system with higher security can be constructed by allowing only a user who is permitted to perform the operation. In the present embodiment, the registration memory 13 for storing the registered biometric information data of the user and the user memory 15 for storing the user information are described separately, but these are integrated into one memory. Is also possible.
[0023]
As described above, the present authentication system is configured such that a plurality of pieces of user information are assigned to each of a plurality of pieces of registered biometric information data registered in the registration memory 13 and the assigned pieces of user information can be identified by an index. is there.
Here, for example, assuming that the biometric information is a fingerprint, the user memory 15 stores user information a for each finger such as a finger 1A as a thumb and a finger 1B as an index finger as shown in FIG. To d, user information h to k and the like can be assigned.
[0024]
When registering such user information, the registration index information G is added to the registration user information B transmitted from the use device 30, and the user information is stored in an arbitrary index portion of the user memory 15 as shown in FIG. Insert and add. As shown in FIG. 4, it is also possible to register the user information of an arbitrary index of each registered biometric information by overwriting the user information of an arbitrary index portion of the user memory 15 with new user information. .
[0025]
FIG. 5 is a flowchart showing the operation of the present authentication system. The operation of the main part of the present invention will be described according to this flowchart.
First, before starting biometric information collation, the value of the index counter 17 is reset to “0” (step S1). Next, the biometric information of the user is read by the sensor 11, and the verification circuit 12 verifies the biometric information read by the sensor 11 with the registered biometric information in the registration memory 13, and outputs verification data F for the matching registered biometric information. (Step S2).
[0026]
Here, in the present embodiment, at least one of a plurality of registered biometric information registered in the registration memory 13 is set as index-corresponding registered biometric information, and the matching data F output from the matching circuit 12 is used as the index data. If it indicates the corresponding registered biometric information (YES in step S3), the matching circuit 12 outputs the index addition signal K to the index counter 17 and increases the value of the index counter 17 by one (step S4). ), And returns to the reading and matching of the biological information again (step S2). If the collation data F of the collation result is the previous registered biometric information corresponding to the index, the index addition signal K is similarly output to the index counter 17 and the value of the index counter 17 is increased by one (step S3). Step S4), returning to step S2 again to read and collate the biological information.
[0027]
As described above, in the matching circuit 12, each time the biometric information is read by the sensor 11, the biometric information is compared with the registered biometric information in the registration memory 13, and the matching data F indicating the matching result is registered in the index-compatible registered biometric data. In the case of information, an index addition signal K is output to the index counter 17 to perform a process of increasing the value of the index counter 17 by one.
[0028]
On the other hand, if the matching result by the matching circuit 12 does not indicate the registered biometric information corresponding to the index (NO in step S3), the matching indicating the type of the registered biometric information output by the matching circuit 12 based on the matching of the matching is performed. The user information in the user memory 15 is searched and specified from the data F and the index information I indicating the value of the index counter 17 at that time (step S5). Then, the specified user information is output to the keyboard emulator 14 (step S6). When the user information output from the user memory 15 is input, the keyboard emulator 14 converts the user information into a keystroke signal J of the keyboard and transmits it to the device 30 as communication data H via the communication circuit 16 as described above. I do.
[0029]
As described above, in the present embodiment, it is possible to assign a plurality of pieces of user information to each registered biometric information (for example, each finger in the case of a fingerprint), and it is possible to register and use more user information. Become. For example, when the user information is a password or the like for a service in the device 30 to be used, when a new password is added to the user memory 15 as user information, registration using “addition of user information” is performed. Passwords can also be retained and output. This makes it possible to output both the old and new passwords using the index even when it is necessary to input the old and new passwords on the service password update screen or the like on the device 30 to be used. It is possible to respond.
[0030]
In the above description, when the value of the index counter 17 is increased, a method of determining the registered biometric information corresponding to the index in advance has been described. However, the value of the index counter 17 is changed according to the position of the living body such as a finger on the sensor 11. It is also possible to increase it.
[0031]
That is, as shown in FIG. 6, the user places his / her finger in various directions as shown in FIGS. 6 (a) to 6 (c) with respect to the sensor 11 for reading a fingerprint. The direction of the placement is detected, and the value of the index counter 17 is increased based on the detection result.
[0032]
Further, as shown in FIG. 7, a switch 18 or the like may be provided on the authentication token 10, and the value of the index counter 17 may be increased by the number of times the switch 18 is pressed. In this case, the index addition signal K is not output from the matching circuit 12 to the index counter 17.
[0033]
【The invention's effect】
As described above, according to the present invention, the authentication token, a biometric information sensor that reads the biometric information of the user, a registration memory that previously stores the registered biometric information of the user, and a specific registered biometric information in the registration memory An authentication information output unit capable of outputting a plurality of pieces of unique information of the user corresponding to the stored at least one registered biometric information, and comparing the biometric information read by the biometric information sensor with the registered biometric information in the registration memory. In addition, when the verification result indicates that the verification is successful and the biometric information to be verified is the specific registered biometric information, any one of a plurality of unique information corresponding to the specific registered biometric information is selected from the authentication information output unit. And a collating unit for outputting the user-specific information output from the authentication information output unit to a keyboard tapping signal, and using the converted tapping signal. The authentication system based on biometric information without transmitting dedicated software to a general user device already used by the user because it is configured to transmit and execute the service program on the user device and provide the service to the user. Can be introduced. Also, since a plurality of pieces of user specific information can be assigned to each registered biometric information, more user specific information can be used. For example, when the user-specific information is a password for a service provided by the device to be used, it is possible to hold and output a password before the latest password. This makes it possible to output both the old and new passwords using the index even when the used device requires input of the old and new passwords on the service password update screen and the like.
