Description

  The present invention relates to an individual authentication system that authenticates an individual using biometric information (biometric information) and biometric identification information for identifying and identifying the individual.

  In recent years, attention has been focused on personal authentication technology using biometric information and the like, and it is being put into practical use in various fields (for example, entrance / exit management and automobile keys). Biometric information is a personal fingerprint pattern, palm print pattern, etc., and it is said that there is no one that is the same as another person. By using biometric information, impersonation such as impersonation of another person caused by theft or loss etc. This is because use can be prevented, and authentication with higher security than conventional personal authentication using a personal identification number can be performed. The biometric identification information is, for example, information such as the mother's maiden name and hobbies, or a combination of these, and by using information that only the person can know, high-security authentication is performed in the same manner as biometric information. sell.

  Various proposals have been made as attention is focused on personal authentication technology using biometric information or the like. For example, Patent Document 1 discloses a card registration apparatus that registers biometric information of a plurality of users on a single IC card, and biometric information of a user who is to perform personal authentication. A personal authentication system is disclosed that includes a personal authentication device that determines a user as a genuine user when the biometric information of the user matches the biometric information of any user of the IC card as compared with the information.

As described above, personal authentication systems using biometric information generally register feature data such as a fingerprint pattern in an authentication device in advance, input the feature data to the authentication device at the time of authentication, and register in the authentication device. It is a mechanism for performing personal authentication by determining whether or not the inputted feature data matches the inputted feature data within a predetermined error range.

  However, the conventional personal authentication system has a problem that the recognition rate when reading biometric information such as fingerprints and irises on a device is low, and that it takes time for recognition. For example, in the case of authentication by fingerprint, a person with a thin fingerprint must repeat the input many times, and in the case of authentication by iris, the recognition rate changes depending on the degree of light irradiation. It is hard to say that the system has reached a satisfactory level in terms of practicality.

  On the other hand, in a conventional personal identification system using a personal identification number, which is considered to be at a high level in terms of practicality, security may be improved by complicating the mechanism for entering the personal identification number, but the personal identification number is forgotten. And there is a problem that input takes time. Similarly, in the case of a personal authentication system based on biometric identification information, there is a problem that forgetfulness and input time are required.

  Therefore, the present invention has been made in view of the above problems, is improved in recognition rate and recognition processing time, has excellent practicality, and can prevent unauthorized use such as impersonation of others caused by theft or loss. An object is to provide an individual authentication system with high security.

As a result, biometric information and the like are transmitted from the device to be authenticated to the authentication device when receiving authentication, so that the time for the authentication process can be shortened. In addition, since the device to be authenticated has its own power supply, the readable distance of biometric information and the like in the authentication device can be dramatically increased, and the operability during authentication can be improved.

  Here, the device to be authenticated may further include an erasing unit that erases biometric information and / or biometric identification information stored in the storage unit, and the device to be authenticated further includes the device to be authenticated. Detecting means for detecting the wearing state of the body, and the transmitting means directs the biological information or / and the biological identification information to the authentication device when detecting that the detecting means is in the wearing state. The erasure unit erases the biometric information and / or the biometric identification information stored in the storage unit when the detection unit does not detect that the detection unit is in the wearing state within a predetermined time. preferable. As a result, the device to be authenticated can transmit biometric information and the like only after being attached to the user's body, and the biometric information and the like are erased after a lapse of a predetermined time after being detached from the user's body. Use can be effectively prevented, and a highly secure individual authentication system is realized.

  Moreover, it is preferable that the transmission means includes a radio wave state detection unit that detects a radio wave state and an interference prevention unit that controls transmission of the biological information or / and biometric identification information. With such a configuration, even when a plurality of users concentrate on the authentication device at a time, the effect that the authentication processing on the authentication device side can be performed smoothly is exhibited.

In addition, since the device to be authenticated has its own power supply and transmits the biometric information and the like that it holds to the authentication device, it is possible to dramatically increase the distance at which the authentication device can read the biometric information and the like. Furthermore, since the device to be authenticated is attached to the user's body, it becomes possible to transmit biometric information and the like, and the biometric information and the like that is held is erased when a predetermined time elapses after being detached from the user's body.

  Hereinafter, the best mode for carrying out the present invention will be described in detail. In the following, unless otherwise specified, the term biometric information includes the meaning of biometric identification information or can be replaced with the meaning of biometric identification information.

First, an individual authentication system according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing an external configuration of an individual authentication system according to an embodiment of the present invention.
The individual authentication system 1 is a system that authenticates the legitimacy of an individual (user) using biometric information, and acquires the biometric information from the device to be authenticated 100 that is worn on the body of the user to be authenticated and the device to be authenticated 100. And an authentication device 200 that performs user authentication.

  The device to be authenticated 100 stores the biometric information of the user, and is a device that can transmit the biometric information to the authentication device 200 when worn on the user's body, and is represented by a wristwatch in this figure. ing.

  The authentication device 200 stores therein biometric information (authentication information) for performing user authentication, receives the biometric information from the device to be authenticated 100, and performs user authentication by collating with the authentication information. A receiving unit 201 that receives biometric information transmitted from the device to be authenticated 100 is provided. In this figure, the authentication device 200 is represented by a gate device.

FIG. 2 is a block diagram showing a functional configuration of each device constituting the individual authentication system 1.
As illustrated in FIG. 2, the device to be authenticated 100 includes, as functional components, an attachment detection unit 110, a power supply unit 120, a communication unit 130, a biological information storage unit 140, an operation input unit 150, an information erasure unit 160, An information registration unit 170, an electronic key information storage unit 180, and a decryption unit 190 are provided.

  The wearing detection unit 110 is a sensor that detects that the device to be authenticated 100 is worn on the user's body. For example, a temperature sensor that senses the user's body temperature, a sensor that senses the user's pulse, or a sensor that senses skin with light can be used as the attachment detection unit 110. When detecting that the device to be authenticated 100 is attached (attached state), the attachment detection unit 110 instructs the power supply unit 120 to supply power to each unit constituting the device to be authenticated 100 and performs communication. The unit 130 is activated. Further, when detecting that the device to be authenticated 100 is not attached (non-attached state), the attachment detection unit 110 outputs an instruction to stop power supply to the power supply unit 120 and the communication unit 130. Stop the operation. Further, when the attachment detection unit 110 detects that the device is not attached, the attachment detection unit 110 notifies the information erasure unit 160 that the authentication target device 100 is not attached. The attachment detection unit 110 may always check the attachment state, but may check the attachment state intermittently at a predetermined time interval.

  The power supply unit 120 supplies power to each unit constituting the device to be authenticated 100 or stops power supply based on an instruction from the mounting detection unit 110. For example, the power supply unit 120 drives each unit of the device to be authenticated 100 by generating power using a temperature difference between the user's body temperature and the outside air temperature (by a power generation method using a so-called Seebeck effect). Here, the power supply unit 120 may use a solar battery, or may combine the power generation using the temperature difference and the solar battery.

  The communication unit 130 is a communication interface that transmits biometric information and electronic key information to the authentication device 200. The communication unit 130 operates based on a start instruction and an operation stop instruction from the mounting detection unit 110. When the communication unit 130 acquires a biometric information transmission instruction from the operation input unit 150, the communication unit 130 reads the biometric information from the biometric information storage unit 140. Then, the electronic key information is received from the decryption unit 190, and the biometric information or the like is transmitted to the authentication device 200 by radio using a predetermined frequency band. In addition, the communication unit 130 can communicate with a biometric information input device that reads the biometric information of the user, a device that holds electronic key information incorporated in the device to be authenticated 100, and the like. When information or electronic key information is received, the received information is output to the information registration unit 170. Further, the communication unit 130 includes a radio wave state detection unit 131 and an interference prevention unit 132.

The radio wave status detection unit 131 is a processing unit that monitors the radio wave status, and outputs to the interference prevention unit 132 when the communication unit 130 detects a radio wave in the same band as the frequency at which biological information is transmitted.
The interference prevention unit 132 is a CPU that controls the operation of the communication unit 130 for anti-co-region (interference prevention). When the radio wave condition detection unit 131 detects the same radio wave as the frequency at which the biological information is transmitted, the interference prevention unit 132 performs control so that the biological information is not transmitted until it is detected that the radio wave has stopped. The interference prevention unit 132 may use other interference prevention methods. For example, an FDMA (Frequency Division Multiple Access) system that divides the frequency band to avoid mutual interference between the devices to be authenticated 100, or a TDMA (Time Division) that prevents mutual interference between the devices to be authenticated 100 by dividing the time zone. It is also possible to use a multiple access (CDMA) system, a code division multiple access (CDMA) system that prevents interference by encoding, and the like.

  The information erasure unit 160 is a processing unit that erases the biological information recorded in the biological information storage unit 140. The information erasure unit 160 erases the biometric information recorded in the biometric information storage unit 140 based on the biometric information erase instruction received from the user via the operation input unit 150. In addition, the information erasing unit 160 includes a timer, and starts measuring time when the mounting detection unit 110 detects that it is not mounted. Then, if it is not detected that the mounting detection unit 110 is in the mounting state within a predetermined time, the biological information recorded in the biological information storage unit 140 is deleted.

  The information registration unit 170 is a processing unit that records the user's biometric information in the biometric information storage unit 140 and records the electronic key information in the electronic key information storage unit 180. The information registration unit 170 acquires the biological information received by the communication unit 130 and stores it in the biological information storage unit 140. In addition, when the electronic key information received by the communication unit 130 is acquired, the information registration unit 170 encrypts the acquired electronic key information and stores it in the electronic key information storage unit 180 in order to improve security. Here, the electronic key information may be transmitted to the device to be authenticated 100 after being encrypted in advance by the device that transmits the electronic key to the communication unit 130.

  The electronic key information storage unit 180 is a recording medium having a storage area for recording electronic key information, and is realized by a memory chip such as a nonvolatile memory. In the electronic key information storage unit 180, electronic key information for multiple uses is recorded for each field of use. Here, “multiple uses” means, for example, a use as a substitute for an entrance / exit management card (company use), a use as a substitute for a cash card or a credit card (personal use), a license or a commuter pass, etc. Application (public use).

  The decryption unit 190 is a processing unit that releases (decrypts) the encryption of the electronic key information recorded in the electronic key information storage unit 180. When the decryption unit 190 detects that the mounting detection unit 110 is in the mounted state, the decryption unit 190 reads the electronic key information from the electronic key information storage unit 180, decrypts it, and outputs it to the communication unit 130. At this time, the decryption unit 190 reads out the electronic key information selected by the user via the operation input unit 150 from among the plurality of electronic key information, decrypts it, and outputs it to the communication unit 130.

The authentication apparatus 200 includes a communication unit 210, an authentication unit 220, and an authentication information storage unit 230.
The communication unit 210 is a communication interface that receives biometric information and electronic key information transmitted from the device to be authenticated 100. The communication unit 210 receives biometric information and the like from the device to be authenticated 100 by radio using a predetermined frequency band, and outputs the received biometric information and the like to the authentication unit 220.

The authentication unit 220 is a processing unit that performs user authentication by checking biometric information and the like output from the communication unit 210 with authentication information recorded in the authentication information storage unit 230.
The authentication information storage unit 230 is a recording medium having a storage area for storing authentication information, and is realized by a hard disk or the like.

Next, a processing procedure of the individual authentication system 1 configured as described above will be described.
FIG. 3 is a sequence diagram showing a processing procedure of the individual authentication system.
First, when the device to be authenticated 100 is attached to the user's body, the attachment detection unit 110 detects the attachment state (S10) and activates the communication unit 130 (S12).

  Next, when receiving an operation for instructing transmission of biometric information from the user via the operation input unit 150, the communication unit 130 reads the biometric information from the biometric information storage unit 140 and transmits it to the authentication device 200 (S14).

  When the authentication device 200 receives the biometric information via the communication unit 210, the authentication unit 220 performs user authentication by comparing the received biometric information with the authentication information recorded in the authentication information storage unit 230 (S16). ).

  Here, when the device to be authenticated 100 is detached from the user's body, the attachment detection unit 110 detects the non-wearing state (S20), and informs the information erasing unit 160 that the device to be authenticated 100 is in the non-wearing state. In addition, the operation of the communication unit 130 is stopped (S22).

  When the information erasure unit 160 receives the notification of the non-wearing state from the wearing detection unit 110, the information erasing unit 160 starts a timer and measures the duration of the non-wearing state. Then, if it is not detected that the mounting detection unit 110 is in the mounting state within a predetermined time (T1), the biological information recorded in the biological information storage unit 140 is deleted (S24).

Next, a processing procedure in the case where the device to be authenticated 100 decrypts the encrypted electronic key and transmits it to the authentication device 200 together with biometric information will be described.
FIG. 4 is a flowchart showing a processing procedure when the electronic key is decrypted and transmitted.

  Similar to the sequence diagram shown in FIG. 3, when the device to be authenticated 100 is worn on the user's body, the wearing detection unit 110 detects the wearing state (S10) and activates the communication unit 130 (S12). .

  Here, when a plurality of pieces of electronic key information are stored in the electronic key information storage unit 180 (Yes in S30), the authenticated apparatus 100 designates the electronic key information to be transmitted from the user via the operation input unit 150. (S32). When the electronic key information is designated, the device to be authenticated 100 reads out the designated electronic key information from the electronic key information storage unit 180 in the decrypting unit 190, decrypts it, and outputs it to the communication unit 130 (S34).

  On the other hand, when a plurality of pieces of electronic key information are not stored in the electronic key information storage unit 180, that is, only one piece of electronic key information is stored (No in S30), the authenticated apparatus 100 uses the decryption unit 190. The electronic key information is read from the electronic key information storage unit 180, decrypted, and output to the communication unit 130 (S36).

  Thereafter, the device to be authenticated 100 transmits the decrypted electronic key information to the authentication device 200 together with the biometric information read from the biometric information storage unit 140 in the communication unit 130 (S38), and ends the processing operation.

Further, processing when registering biometric information in the device to be authenticated 100 will be described.
As described above, the device to be authenticated 100 holds biometric information in advance, and transmits the held biometric information to the authentication device 200 by using the transmission button as a trigger when the device is in a wearing state. In addition, the authenticated apparatus 100 erases the stored biometric information when a predetermined period of time has passed since the apparatus is not attached. Therefore, it is necessary to perform initial registration or re-registration of biometric information in the device to be authenticated 100.

FIG. 5A shows an example of biometric information registration processing.
In this figure, as an example of biometric information registration processing, a biometric information registration apparatus 300 including a biometric information acquisition unit 301 such as a fingerprint sensor reads the biometric information of the user, and the biometric information thus read is wirelessly authenticated. The structure which transmits to is shown. In this configuration, the device to be authenticated 100 receives the user's biometric information via the communication unit 130 and records the biometric information received by the information registration unit 170 in the biometric information storage unit 140. Here, the transmission of the biometric information from the biometric information registration apparatus 300 to the authenticated apparatus 100 may be performed by the cable 302 shown in FIG. Moreover, although the structure integrated with the biometric information acquisition part 301 was demonstrated about the biometric information registration apparatus 300, for example, it replaces with the reader which acquires biometric information, and the personal computer connected with this reader Also good. Note that when biometric identification information is registered, an input of biometric identification information from a user may be accepted via an input device such as a keyboard of a personal computer.

The procedure of biometric information registration processing will be described below.
FIG. 6 is a flowchart showing a procedure of biometric information registration processing.
First, when the attachment detection unit 110 detects the attachment state (S40), the device to be authenticated 100 activates the communication unit 130. Then, the communication unit 130 refers to the biometric information storage unit 140 to determine whether biometric information is recorded (S42).

  When biometric information is not recorded (Yes in S42), the biometric information registration device 300 accepts registration of biometric information (S44), and transmits the input biometric information to the device to be authenticated 100.

  The device to be authenticated 100 receives biometric information to be registered from the biometric information registration device 300 via the communication unit 130, and outputs the received biometric information to the information registration unit 170. Then, in the information registration unit 170, the device to be authenticated 100 stores the biometric information in the biometric information storage unit 140 (S46) and ends the processing operation.

  As described above, the device to be authenticated 100 can transmit biometric information held by being attached to the user's body, and cannot transmit biometric information by being detached from the user's body. To do. Therefore, it is preferable to implement | achieve the to-be-authenticated apparatus 100 as a jewelry always mounted | worn with a user's body.

FIG. 7A shows an example of the appearance when the device to be authenticated 100 is a wristwatch. FIG. 7B shows an example of the appearance from the back of the wristwatch.
As shown in FIG. 7A, a transmission button 101 for instructing transmission of biological information, a selection button 102 for selecting electronic key information to be transmitted, and a stored biological body are provided on the side of the wristwatch case. An erasing button 103 for instructing erasing of information is provided, and a thermoelectric element for generating operating power of the wristwatch, a memory chip for storing biological information, and an antenna for transmitting biological information are incorporated in the watch case. . Further, as shown in FIG. 7B, an attachment detection sensor 104 for detecting attachment of a wristwatch is provided on the back surface in contact with the user's body. By doing in this way, the to-be-authenticated apparatus 100 is realizable as a wristwatch.

  Similarly, the device to be authenticated 105 can be realized as a ring as shown in FIG. 7C, and the device 106 to be authenticated can be realized as a pendant as shown in FIG. 7D. is there.

  By the way, the conventional individual authentication system has a configuration (passive method) in which the device to be authenticated does not have a power supply by itself and acquires the operating power from the authentication device, and the authentication device can acquire biometric information from the device to be authenticated. Is about a few centimeters. On the other hand, the individual authentication system according to the present embodiment has a configuration (active method) in which the device to be authenticated 100 generates power with its own power supply as described above. The distance that can be acquired from the device to be authenticated 100 can be about several meters, and the communication performance in the system and the operability when receiving authentication can be dramatically improved. On the other hand, when the communication performance between the authenticated device 100 and the authentication device 200 is improved, interference when a plurality of users concentrate on the authentication device 200 at a time can be a problem.

Hereinafter, interference prevention processing in the individual authentication system according to the present embodiment will be described.
FIG. 8 is a diagram for explaining interference prevention processing.

  In this figure, it is shown that the device to be authenticated 100 built in the wristwatch is transmitting biometric information to the receiving unit 201 of the authentication device 200. On the other hand, it is shown that the device to be authenticated 100a built in the hat and the device to be authenticated 100b built in the ring stop transmitting the biometric information to the receiving unit 201 of the authentication device 200.

  That is, when the device to be authenticated 100 is transmitting biometric information to the receiving unit 201, the radio wave status detection unit 131 of the device to be authenticated 100a and the device to be authenticated 100b detects the same radio wave as the frequency at which the biometric information is transmitted. Therefore, until the transmission of the biometric information from the authenticated device 100 to the receiving unit 201 is completed, the interference prevention unit 132 of the authenticated device 100a and the authenticated device 100b does not transmit the biometric information. So that it is controlled.

By doing in this way, even if a plurality of users concentrate on the gate at a time, the authentication process on the authentication device 200 side can be performed smoothly.
As described above, according to the individual authentication system according to the present embodiment, biometric information is recorded in advance in a device to be authenticated, and biometric information is transmitted from the device to be authenticated to the authentication device to perform user authentication. The processing time at the time of authentication can be shortened. In addition, it is not necessary to input biometric information at the time of authentication, and sufficient input time can be taken. For example, even a user with a thin fingerprint can register accurate information in both the authentication target device and the authentication device. is there.

  In addition, since the device to be authenticated has its own power supply and transmits the stored biometric information to the authentication device, the authentication device can dramatically increase the distance at which biometric information can be read, and can be used for authentication. Can be improved.

Furthermore, the device to be authenticated enables transmission of biometric information by being worn by the user, and erases the biometric information that is retained when a predetermined time elapses after being attached and detached, so that unauthorized use such as impersonation by others It is possible to realize an authentication system with high security that can effectively prevent the problem. In addition, the authentication device is provided with an encryption unit that encrypts communication data such as biometric information transmitted to the authentication device, and the communication data is encrypted and transmitted, and the authentication device decrypts the communication data. By providing the decryption unit, it is possible to further improve the security.

Furthermore, by recording electronic key information for a plurality of purposes for each field of use in the device to be authenticated, it is possible to receive various authentications with one device.

  As described above, the individual authentication system according to the present embodiment simultaneously improves the recognition rate of biometric information and the authentication processing time, which have been problems, and prevents unauthorized use caused by theft or loss.

The individual authentication system according to the present invention has been described based on the embodiment, but the present invention is not limited to this embodiment.
For example, in the above-described embodiment, the authentication target device transmits biometric information to the authentication device when receiving an operation of pressing the transmission button. However, the authentication device transmits radio waves having a predetermined frequency for requesting acquisition of biometric information. May be transmitted to the surroundings, and when the device to be authenticated receives the radio wave, the biometric information may be transmitted to the authentication device.

  In the above-described embodiment, the trigger for erasing the biometric information in the device to be authenticated has been described as an operation of pressing the user's erasure button after a predetermined time has passed in the non-wearing state. The trigger may be that a wireless signal for erasing the biological information is received from an external device.

  Furthermore, in the above embodiment, an example in which the device to be authenticated is built in a wristwatch, a ring, or a pendant has been described, but it goes without saying that it may be built in other accessories such as a bracelet. It may be built in.

  Furthermore, the device to be authenticated in the individual authentication system according to the present invention is attached to animals other than humans, for example, pets such as dogs and cats, livestock such as cows and pigs, and the ecological trends of these animals are monitored. It is also possible to apply to the system which does.
