  However, in the technology for preventing unauthorized transactions using a password, when a credit card is stolen by an unauthorized user other than a regular user, as shown below, the password is analogized by the unauthorized user, Using a stolen credit card, there was a possibility that the transaction was carried out illegally. In other words, passwords are usually four-digit numbers in the form of passwords, and random passwords are difficult to remember. It was relatively easy to analogize. For this reason, a password may be inferred by an unauthorized user and a transaction may be performed illegally using a stolen credit card.

(Processing-biological information acquisition processing)
First, the biological information acquisition process will be described. FIG. 4 is a flowchart of the biometric information acquisition process (in the following description of each process, step is abbreviated as “S”). The “biometric information acquisition process” is a process for acquiring biometric information, specifically, a process for acquiring information on the shape of a fingerprint, which is performed prior to the biometric authentication process, and is shown in FIG. This is processing performed using the power generated by the power generation unit 11. The timing at which this biometric information acquisition process is activated is arbitrary, but for example, the user holds the one side (+ X direction) portion of the card 10 in FIG. 2 with his hand and uses his / her finger (eg, thumb) as a fingerprint. By applying a force to the holding portion while being in contact with the sensor 103, the power generation plate 104 is bent (that is, deformed) together with the card casing 101, and the power generation plate 104 generates power to generate power. A description will be given after the activation, assuming that when the generated power is supplied to the fingerprint sensor 103, the fingerprint sensor 103 is activated and starts executing.

  First, as shown in FIG. 4, in SA1, the biological information acquisition unit 12 of the card 10 acquires biological information. Specifically, when the biometric information acquisition process is activated, information on the shape of the fingerprint is acquired as biometric information using the power generated by the power generation unit 11 in FIG. Specifically, the fingerprint sensor 103 in FIG. 2 of the biometric information acquisition unit 12 uses the power supplied to the power generation plate 104 of the power generation unit 11 through the power supply wiring 106 and uses the power of the user who is in contact with the user. The fingerprint shape is detected, and the detected fingerprint shape information is acquired as biometric information.

  Returning to FIG. 4, in SA <b> 2, the biological information acquisition unit 12 of the card 10 records the biological information in the biological information storage unit 13. Specifically, the biometric information acquired in SA1 is recorded in the biometric information storage unit 13 in FIG. 1 using the power generated by the power generation unit 11 in FIG. 1 when the biometric information acquisition process is activated. Specifically, the fingerprint sensor 103 in FIG. 2 of the biometric information acquisition unit 12 uses the power supplied to the biometric information acquired in SA1 from the power generation plate 104 of the power generation unit 11 via the power supply wiring 106. By transmitting to the IC module 102 via the data communication wiring 105, the data is recorded in the “partial area” in the storage unit (not shown) of the chip layer 102 b of the IC module 102. When the biometric information acquisition process is started, the power generated by the power generation unit 11 in FIG. 1 is transferred to the above-described holding capacitor (not shown) in the chip layer 102b in FIG. 3 via the capacitor power line (not shown). Since the charged holding capacitor continues to provide power to the “partial region” (that is, the biological information storage unit 13), the biological information storage unit The biometric information recorded in 13 is retained, and is erased when a predetermined time elapses after the biometric information acquisition process is started. In this way, by limiting the time during which biometric information is retained, the timing (that is, time) at which biometric authentication described later can be performed can be limited. Unauthorized use can be prevented and security can be further improved. This completes the biological information acquisition process.

After the reading side power supply terminal is connected, and the reading side communication terminal (not shown) of the reading device 20 is connected to the card side communication terminal 102a2, the power from the reading device power supply unit 23 is changed to the reading side not shown. A description will be given after the activation, assuming that when the IC module 102 is supplied via the card-side power supply terminal and the card-side power supply terminal 102a1, the activation is started.

  First, as shown in FIG. 5, in SB1, the biological information analysis unit 15 of the card 10 reads the biological information. Specifically, the biometric information recorded in the biometric information storage unit 13 (that is, the biometric information acquired in SA1 of FIG. 4) is read using the power from the reading device power supply unit 23 of FIG. Specifically, the biological information analysis unit 15 uses the power from the reading device power supply unit 23 to access the “partial region” described above in the storage unit (not shown) of the chip layer 102b of the IC module 102 of FIG. Then, fingerprint shape information is read as biometric information from the accessed “partial region”.

  Returning to FIG. 5, in SB2, the biometric information analysis unit 15 of the card 10 performs biometric authentication. Specifically, using the power from the reader power supply unit 23 in FIG. 1, feature points are extracted from fingerprint shape information that is biometric information read in SB1, and the pre-registered biometric in the information storage unit 14 is extracted. Read the feature point information, compare the extracted feature points (hereinafter referred to as extracted feature points) with the feature points specified by the pre-registered biometric feature point information (hereinafter referred to as pre-registered feature points), and whether or not they match If they match, it is determined that the biometric authentication is acceptable, and if they are different, the biometric authentication is determined to be unacceptable. Specifically, the biometric information analysis unit 15 uses the power from the reading device power supply unit 23 to extract feature points from fingerprint shape information that is biometric information read by the SB1, and the IC module of FIG. After accessing the aforementioned “other partial area” in the storage unit (not shown) of the chip layer 102b of 102 and reading pre-registered biometric feature point information from the accessed “other partial area”, The extracted feature point and the pre-registered feature point are compared to determine pass or fail.

  Returning to FIG. 5, in SB3, the biometric information analysis unit 15 of the card 10 determines whether or not the biometric authentication has passed. Specifically, the determination is made based on the processing result of SB2 using the power from the reader power supply unit 23 of FIG. If it is determined that the biometric authentication is not successful in SB2, it is determined that the biometric authentication is not successful (NO in SB3), and the process is terminated. If it is determined that the biometric authentication of SB2 is acceptable, it is determined that the biometric authentication has passed (YES in SB3), and the process proceeds to SB4.

  Returning to FIG. 5, in SB4, the biological information analysis unit 15 of the card 10 transmits the card ID. Specifically, the card ID in the information storage unit 14 is read using the power from the reader power supply unit 23 in FIG. 1, and the read card ID is transmitted via the communication interface unit 16. Specifically, the biological information analysis unit 15 uses the power from the reading device power supply unit 23 to “the other part of the region” described above in the storage unit (not shown) of the chip layer 102b of the IC module 102 of FIG. , Read the card ID from the accessed “other part of the area”, and read the card ID into the card side communication terminal 102a2 and the reading side communication terminal (not shown) (that is, the communication interface unit in FIG. 1). 21) to the reading device 20. This completes the biometric authentication process. After this, the information processing unit 24 of the reading device 20 that has received the card ID transmitted in SB4 of FIG. 5 performs a known process to make a settlement.

  By performing these biometric information acquisition processing and biometric authentication processing, payment can be made only when the card 10 is held and used by a “regular user”. Can be used to prevent unauthorized payments from being made. Here, the “regular user” is a user who appropriately owns the card 10, specifically, a user whose pre-registered biometric feature point information is registered in the information storage unit 14 of FIG. 1. Yes, an “illegal user” is a user who possesses the card 10 by an illegal act such as theft. Specifically, pre-registered biometric feature point information is registered in the information storage unit 14 of FIG. Not a user.

(Effect of embodiment)
As described above, according to the present embodiment, the biometric information acquisition unit 12 acquires the biometric information of the user using the power generated by the power generation unit 11 that generates power using environmental energy. Since there is no need to provide a dedicated device for acquiring the user's biological information on the reading device 20 side, the reading device 20 does not need to be significantly modified. That is, for example, in the case of a conventional card authentication system compatible with biometric authentication, it is necessary to provide a separate biometric information acquisition device such as a fingerprint on the card reading device side, but a conventional card (IC chip card as an example) reading device. Can be used as it is, and the security level can be increased without introducing a new card reader compatible with biometric authentication in stores, taxis and the like that use cards. In addition, for example, since the biometric information acquired on the card 10 side can be used for security, it is possible to prevent fraud (for example, fraudulent payment, etc.) from being performed using the card 10, and security can be improved. Can be improved. Further, for example, since it is not necessary to provide a battery in the card 10 in order to secure power for acquiring biometric information, the shape of the card 10 depends on the shape of the battery, or the continuous use time of the card 10 It is possible to provide an easy-to-use card 10 that can be continuously used in a thin shape (for example, a thickness of 0.76 mm) without being influenced by the battery life.

  In addition, since the biometric information acquisition unit 12 is provided around the power generation unit 11, for example, when the biometric information acquisition unit 12 acquires user fingerprint information as biometric information, the user manually holds the card 10. Since it is possible to generate electric power and acquire biometric information without having to hold it in a held state, the convenience of the card 10 can be improved.

  In addition, since the power generation unit 11 generates power when it is deformed by the force applied by the user, for example, the user can generate power by a simple operation of applying force to the card 10. Convenience can be further improved.

  In addition, since the biometric authentication is performed based on the biometric information acquired by the biometric information acquisition unit 12, for example, the card 10 performs authentication that is difficult to perform fraud, so that security can be improved. Further, for example, since it is not necessary to provide a configuration for performing biometric authentication on the reading device 20 side, it is possible to improve security without significantly modifying the existing reading device 20.

[Modifications to Embodiment]
Although the embodiments of the present invention have been described above, the specific configuration and means of the present invention may be arbitrarily modified and improved within the scope of the technical idea of the present invention described in the claims. Can do. Hereinafter, such a modification will be described.

(About problems to be solved and effects of the invention)
First, the problems to be solved by the invention and the effects of the invention are not limited to the above-described contents, and the present invention solves the problems not described above or has the effects not described above. There are also cases where only some of the described problems are solved or only some of the described effects are achieved. For example, even if it is difficult to improve security with a conventional system, the problem of the present application is solved when the means of the present invention is different from the means of the conventional system.

(About distribution and integration)
Further, each of the electrical components described above is functionally conceptual and does not necessarily need to be physically configured as illustrated. In other words, the specific forms of distribution and integration of each unit are not limited to those shown in the drawings, and all or a part thereof may be functionally or physically distributed or integrated in arbitrary units according to various loads or usage conditions. Can be configured. The “system” in the present application is not limited to one configured by a plurality of devices, but includes one configured by a single device. In addition, the “apparatus” in the present application is not limited to one configured by a single apparatus, but includes one configured by a plurality of apparatuses. For example, at least one of the units of the card 10 in FIG. 1 may be provided in the reading device 20 or a device other than the card 10 and the reading device 20, and at least one of the units of the reading device 20 may be provided in the card 10 or the card 10. Also, it may be provided in a device other than the reading device 20.

(About shape, numerical value, structure, time series)
Regarding the constituent elements exemplified in the embodiment and the drawings, the shape, numerical value, or the structure of a plurality of constituent elements or the mutual relationship in time series may be arbitrarily modified and improved within the scope of the technical idea of the present invention. Can do.

(About information transmission)
Moreover, although the case where card ID is transmitted by SB4 of FIG. 5 was demonstrated in the said embodiment, it is not restricted to this. For example, after the determination of SB3 is omitted, the result of biometric authentication in SB2 and the card ID may be transmitted from the card 10 of FIG. In this case, the reading device 20 may perform payment only when the result of “Biometric authentication is passed” is received.

(Deleting biometric information)
Further, immediately after the biometric information is read in SB1 in FIG. 5 of the above embodiment, the biometric information recorded in the biometric information storage unit 13 in FIG. 1 is explicitly deleted using a known means. Also good. When comprised in this way, it can prevent that the card | curd 10 is used illegally or the biometric information of the biometric information storage part 13 is acquired illegally. Note that reading biometric information in SB1 corresponds to an example of “predetermined case”. Also, for example, after providing an ultra-thin battery and a real-time clock that operates with the power of the battery on the card 10, the time recorded when biometric information is recorded at SA2 in FIG. 4 is also recorded. When the biometric information analysis unit 15 reads biometric information in SB1 of FIG. 5, referring to the above-mentioned time, the referred time exceeds a predetermined time (for example, 5 to 6 seconds) from the current time. If the card is a previous one, the biometric information in the biometric information storage unit 13 is erased in consideration of the possibility that the card 10 is illegally used. The authentication process may be terminated. In the case of such a configuration, the biological information storage unit 13 of FIG. 1 may be realized by a nonvolatile memory such as a flash memory. Note that the case where the referenced time is before the current time and exceeds a predetermined time (for example, 5 to 6 seconds or the like) corresponds to an example of “predetermined case”.

(About the biological information analysis unit)
Moreover, although the said embodiment demonstrated the case where the biometric information analysis part 15 (namely, authentication means) was provided in the card | curd 10 as shown in FIG. 1, it is not restricted to this. For example, the authentication unit may be provided only in the reading device 20, or the authentication unit may be provided in both the card 10 and the biological information analysis unit 15.

  First, the case where the authentication unit is provided only in the reading device 20 may be specifically configured as follows. That is, the pre-registered biometric feature point information in the information storage unit 14 of FIG. 1 is omitted from the card 10 and recorded in the information storage unit 22 of the reading device 20 in association with the card ID, and authentication means (that is, biometric information). The analysis unit 15) may be omitted from the card 10 and provided in the reading device 20. With this configuration, the card 10 omits SB2 and SB3 after executing SB1 in FIG. 5, and the biometric information recorded in the biometric information storage unit 13 together with the card ID in SB4 (that is, FIG. 4) is transmitted to the reading device 20. On the other hand, the authentication unit of the reading device 20 performs biometric authentication based on the transmitted biometric information and pre-registered biometric feature point information in the information storage unit 22 as in the case of SB2 in FIG. A settlement may be made based on the result. When configured in this manner, since the biometric information is transmitted together with the card ID, for example, biometric authentication can be performed on the reading device 20 side using the transmitted card ID and biometric information, thereby improving security. be able to. Further, for example, the processing load on the card 10 side can be reduced by not performing biometric authentication on the card 10 side.

  Specifically, the case where the authentication unit is provided in both the card 10 and the biological information analysis unit 15 may be configured as follows. That is, the pre-registered biometric feature point information in the information storage unit 14 of FIG. 1 is recorded in the information storage unit 22 of the reading device 20 in association with the card ID without being omitted in the card 10, and authentication means (that is, biometrics). The information analysis unit 15) may be provided in the reading device 20 without being omitted from the card 10. After configuring in this way, the card 10 reads the biometric information recorded in the biometric information storage unit 13 together with the card ID in SB4 of FIG. 5 (that is, the biometric information acquired in SA1 of FIG. 4) with the reading device 20. Send to. On the other hand, the authentication unit of the reading device 20 may perform the same processing as the above-mentioned “when the authentication unit is provided only in the reading device 20”.

  Further, as in this modification, when “pre-registered biometric feature point information” is used on the reading device 20 side, a safe communication path between the reading device 20 and a data server (not shown) is secured. In this case, the “pre-registered biometric feature point information” is stored in the data server instead of the reading device 20 itself, and the authentication unit of the reading device 20 accesses the data server every time biometric authentication is performed. Pre-registered biometric feature point information may be acquired and processed. When configured in this manner, the possibility that the pre-registered biometric feature point information is illegally obtained from the reading device 20 can be reduced.

(About pre-registered biometric feature point information)
Moreover, although the said embodiment demonstrated the case where the pre-registration biometric feature point information was recorded on the information storage part 14 of the card | curd 10 as shown in FIG. 1, it is not restricted to this. For example, the pre-registered biometric feature point information is combined with the card ID and recorded in the information storage unit 22 of the reading device 20 or the data server described in “(Biometric information analysis unit)”, and the recorded information is used. Thus, biometric authentication may be performed on the card 10 side. Specifically, before performing biometric authentication, the card 10 transmits a request signal including the card ID of the card 10 to the reading device 20 or to the data server via the reading device 20. On the other hand, when receiving the request signal, the data server via the reader 20 or the reader 20 acquires pre-registered biometric feature point information corresponding to the card ID included in the request signal, The acquired pre-registered biometric feature point information may be returned to the transmission source of the request signal. Then, the card 10 uses the pre-registered biometric feature point information returned from the reading device 20 or from the data server via the reading device 20 in the same manner as described in the embodiment or the modification. When the biometric authentication is performed and the biometric authentication is passed, the card ID is transmitted to the reading device 20 together with the fact that the biometric authentication is successful. In addition, the settlement may be performed by a known process.

(About biometric information acquisition unit (1))
Moreover, although the said embodiment demonstrated the case where only one fingerprint sensor 103 of FIG. 3 was exposed on the surface (+ Z direction) surface in the card | curd case 101, it is not restricted to this.

After changing to one having an area of 2 to 1/4 or having a hole corresponding to the outer shape of the fingerprint sensor 103), the horizontal longitudinal direction (X direction) or the horizontal short direction (Y direction) In this case, the fingerprint sensor 103 and the power generation plate 104 may be configured not to overlap each other in the thickness direction (Z direction) by shifting the fingerprint sensor 103 with respect to the power generation plate 104. In this case, the fingerprint sensor 103 and the power generation plate 104 may be configured to be provided on the same plane (XY plane). Further, for example, after the power generation plate 104 is divided into two, the fingerprint sensor 103 is divided into two from the left and right (for example, one side (+ X direction) and the other side (−X direction)). It may be sandwiched. Further, for example, the fingerprint sensor 103 and the power generation plate 104 may be formed in an elongated shape, and a plurality of the elongated fingerprint sensor 103 and the elongated power generation plate 104 may be alternately arranged.

  The second configuration is a configuration in which a plurality of sensors are provided. Specifically, a sensor unit (hereinafter referred to as another sensor unit) having a configuration similar to that of the fingerprint sensor 103 in FIG. Only one or a plurality of positions are provided, and different fingerprints are acquired in the fingerprint sensor 103 and other sensor units, and biometric authentication passes for all acquired fingerprints. It may be configured to determine that the biometric authentication has not passed if there is at least one that has not passed biometric authentication. In the second configuration, when only one other sensor unit is provided, the one other sensor unit is arranged on the side opposite to the fingerprint sensor 103 in the thickness direction (Z direction) in FIG. You may provide in the back side (-Z direction) of the body 101. FIG. In this case, a thumb is brought into contact with one of the fingerprint sensor 103 and the other sensor unit, and a finger other than the thumb of the same hand as the above thumb (for example, an index finger) is contacted with the other of the fingerprint sensor 103 or the other sensor unit. Or a middle finger or the like).

In the above embodiment, a plurality of power generation plates 104 in FIG. 3 may be provided after reducing the area. Further, for example, a known piezoelectric bimorph element may be applied as the power generation plate 104 in FIG. Further, for example, the hardness of the card casing 101 is increased so as not to bend, and the inner space of the card casing 101 is expanded so that only the power generation plate 104 is deformed inside the card casing 101 (or The thickness of the power generation plate 104 is reduced), and an operation hole is provided at a position facing the power generation plate 104 in the card housing 101, and the user directly connects to the power generation plate 104 through the operation hole. The power generation plate 104 may be deformed to generate power by applying a force.

(About the power generation part (2))
Moreover, although the said embodiment demonstrated the case where the electric power generation part 11 of FIG. 1 was comprised as what produces electric power when deform | transforming with the force provided from the user, it is not restricted to this. For example, the power generation unit 11 may be configured to generate power when heat is transmitted from the user. Specifically, a thermoelectric element such as a well-known Peltier element, which is an element that generates electricity due to a temperature difference, is provided together with or instead of the power generation plate 104 of FIG. 3, and the card 10 is held against a part of the thermoelectric element. The user can easily transfer heat (for example, the body temperature of the hand), and the counter electrode side is brought into contact with an object having a high specific heat so as not to immediately reach thermal equilibrium. The thermoelectric element may be configured to generate electric power when it is held. In such a configuration, since the power generation unit 11 generates power when heat is transmitted from the user, for example, the user can generate power only by touching the card 10, so that the convenience of the card 10 is further enhanced. Can be improved.

(About the display)
Further, in the above embodiment, a display for displaying the status of the card 10 is provided on the card 10, and information relating to each process in FIGS. 4 and 5 (for example, that SA2 in FIG. 4 has been executed) is displayed on this display. Alternatively, the result of biometric authentication at SB2 in FIG. 5) may be displayed. Any number of displays may be provided at any position with respect to the card 10.

(About the power storage unit)
Further, with respect to the above-described embodiment or modification, a power storage unit (for example, a capacitor) that stores power generated by the power generation unit 11 of FIG. 1 is provided, and the power stored in the power storage unit is used. 4 biological information acquisition processing may be performed. In addition, when there is surplus power in the power storage means, this surplus power may be used as part of the power used in the biometric authentication process of FIG.

In some cases, a known circuit for increasing charging efficiency, including a rectifier circuit (for example, a diode bridge), may be provided as part of the power storage means or as a separate body from the power storage means.

(About application)
Moreover, you may apply the characteristic of the said embodiment and modification to a non-contact-type card | curd. In that case, electric power is supplied from the reader side by means such as electromagnetic induction, and data is transmitted by means such as radio waves. Further, the features of the above-described embodiments and modifications may be applied to a card other than a so-called IC card (for example, a magnetic card).

(About the meaning of the term “send”)
In addition, in the description of the communication interface unit 16 of the above embodiment, “transmit” in “transmitting unit that transmits at least the card ID to the reading device 20” may be regarded as an active meaning. It may be taken as a passive meaning. In the case where it is understood as an active meaning, for example, it may be understood that “the communication interface unit 16 sends a card ID to the reading device 20”. May be read by the reading device 20. Even if this “transmit” is regarded as an active meaning or as a passive meaning, at least a part of the configuration or elements other than the communication interface unit 16 in the card 1, or At least some components or elements in the reading device 20 may transmit at least the card ID to the reading device 20.

(About the meaning of the term “predetermined case”)
The “predetermined case” described as “corresponding” in the above embodiment is a concept indicating the timing at which the biometric information stored in the biometric information storage unit 13 is erased. As described in the embodiment, this is a concept corresponding to a case where a predetermined time has elapsed since power generation by the power generation unit 11 or a case where biometric information is read in SB1 as described in the modification. From the viewpoint of further improving the level of security, the “predetermined case” may be regarded as only “when a predetermined time has elapsed since power generation by the power generation unit 11” or “ It may be considered as a logical sum of “when a predetermined time has elapsed since power generation” and “when biometric information is read with SB1”. When captured in this manner (that is, when “predetermined case” is regarded as at least “when a predetermined time has elapsed since power generation by the power generation unit 11”), that is, predetermined regardless of whether biometric authentication is performed or not. When the biometric information in the biometric information storage unit 13 is erased after a lapse of time), as described in FIG. 4, the authorized user holds the card 10 and performs the operation described in the embodiment, Even if the card 10 is dropped or stolen when the operation is interrupted without inserting the card 10 into the reading device 20 for some reason after the information is recorded in the biometric information storage unit 13, It is possible to prevent payments from being made. That is, since the biometric information of the card 10 is erased when a predetermined time has elapsed since the power generation unit 11 generates power, the operation of obtaining biometric information by another person is omitted and the card 10 is inserted into the reading device 20. Even if it does, payment will not be performed, and it is possible to prevent an illegal payment from being made based on impersonation of a legitimate user by another person.
