The card carrier is generally used for the outer shape of the data carrier, but various forms such as a passport-like booklet, flexible sheet, tag, and stick type are possible. This will be described with reference to FIGS.

  Various types of card types are possible, but a typical example is a type in which the wiring board 11 is sandwiched between card base materials 12 and 13. The card base 12 at this time incorporates an IC module 14, a chip LED 15 as an illuminating means, a microfilm 16 as a transmission image portion, and a microlens 17 as a lens portion, and among these, the IC module 14 and the chip. The LED 15 is wired by the wiring board 11. In the case of the non-contact type or the contact / non-contact type, the wiring board 11 constitutes an antenna as an external interface as well as wiring the IC module 14 and the chip LED 15. In this case, the IC module 14 is configured such that the contact terminal is exposed in the case of the contact type or the contact / non-contact type.

  On the other hand, the chip LED 15, the microfilm 16, and the microlens 17 are configured such that when the chip LED 15 is turned on, the lighting light is transmitted through the microlens 17 and further projected to the outside by the microlens 17. In general, this projection is an enlarged projection, but it is not always necessary to enlarge and project when human visual inspection such as machine verification is not required.

  The illumination means in this case is preferably an LED in terms of ease of control, power consumption, and size, but other illumination means may be used. On the other hand, the transparent image portion has functions that require transparency and data retention. The transmission image area has a large amount of information that can hold the formation of a general microfilm such as a protective layer, photosensitive emulsion layer, antihalation layer, undercoat layer, and support, and can be bent and handled. Although it is easy, it may be the one baked on another glass substrate, and the reduction ratio can be appropriately selected depending on the application. In addition, the lens unit often uses a Fresnel lens or the like on a card, but it may be composed of a projection lens such as a general convex lens or a plurality of lenses.

  Actual control of the illumination means is based on a request from an external communication interface or a request from the arithmetic processing means, and when the control of the illumination means is turned on, a projection image is displayed through the lens unit. Such control is generally programmed in the general-purpose IC module 14, but it does not ask the control method such as using a custom LSI depending on the quantity or using a combination of gate arrays.

  The contents of the program are simply those having communication interface means for transmitting / receiving signals to / from an external device, and the control of the illumination means is based on a request from an external communication interface or a request from an arithmetic processing means. It does not matter if the illumination means can only be controlled.

  In this case, the control of the illumination means may be either based on a request through an external communication interface or a request from the arithmetic processing means, but it may be switched between them. When the control of the lighting means is a request through an external communication interface, it may be processed directly as it is, but normally it is usually processed only when authentication is performed and some authentication work is performed. is there. On the other hand, when the control of the lighting means is based on a request from the arithmetic processing means, the processing may be performed only with information from the inside of the arithmetic processing means, for example, only with the clock. In general, the information is taken in and processed in consideration of the information, and is generally based on the information taken in by the communication interface and is easy to configure.

  The authentication may be owner authentication in general as a data carrier, or may be money amount authentication, qualification authentication, company affiliation authentication, or the like. The authentication method may also be biometric authentication such as a face photograph, fingerprint, voiceprint, etc. in addition to a password, signature, password, and the like.

  An embodiment in which the data carrier of the present invention is implemented in the contact IC card format will be described in detail below with reference to FIGS. Of course, the following example is an example, and various modifications can be made within the scope of the right.

  The contact type IC card of this example is a card substrate made of vinyl chloride having a thickness of 0.2 mm and a wiring substrate 11 made of copper epoxy on one side of a substrate made of glass epoxy having a thickness of 0.2 mm. 12 and a card substrate 13 made of polyethylene terephthalate having a thickness of 0.5 mm. The external dimensions are 54.0 × 85.6 mm, and Rs of 3.18 ± 0.3 are attached to the four corners.

  The card base 12 was incorporated as an IC module 14 using an ISO 7816 IC module. The assembling method was configured such that the wiring side was wired with the wiring substrate 11 and the terminals were exposed.

  The terminal of the IC module of ISO7816 is composed of Vcc, GND, RST, Vpp, CLK, I · O, D +, D−, and the wiring is composed of PORT, Vcc, GND, and of course, PORT, Vcc, Each GND is wired to the wiring board 11, and the LED is driven according to this PORT signal. First, in this case, as shown in FIG. 4, after transmitting the ATR signal as attribute information, the contact block reception is performed. Based on this signal, the authentication operation is performed. When the authentication is successful, the lighting operation is performed. On the other hand, the authentication is performed. If not, the lighting operation is not performed, and in either case, the authentication result is transmitted as a contact block. As shown in FIG. 5, in these operations, after command check, random number generation, ExternalAUTH setting, PIN verification and biometric authentication (fingerprint authentication, etc.) are performed in parallel. Here, after random number generation, random number saving and set are performed, after setting of ExternalAUTH, received data is decrypted, random number comparison of the decrypted result, and collation of received data and stored PIN after PIN verification, biometric authentication After performing biometric data collation after (fingerprint authentication, etc.), if collation using the collation method checked by the command is obtained, status (LED lighting operation) is performed, and the authentication / lighting operation is completed to complete the authentication / lighting operation. Return to the main program. And finally, it returns to the acceptance state of new contact block reception.

  On the other hand, the chip LED 15, the microfilm 16, and the microlens 17 are also sequentially sequentially in the thickness direction so that when the chip LED 15 is lit on the card substrate 12, the lighting light is transmitted through the microlens 17 and projected to the outside by the microlens 17. Incorporated, the chip LED 15 is wired by the wiring board 11.

  Using a chip LED 15 having a thickness of 0.6 × 0.3 mm and a thickness of 0.4 mm, secret information is printed on the microfilm 16 in an area of, for example, 1.0 × 1.0 mm, and the microlens 17 is supported. An undercoat layer, an antihalation layer, a light-sensitive emulsion layer, and a protective layer were sequentially laminated on the body. The lens performance is such that microfilm characters can be seen 10 times at a distance of 10 cm from the card, that is, about 50 × 50 mm. In this case, when the printing area of the microfilm 16 is 5.0 × 5.0 mm, it looks 10 times as well.

  In the case of the non-contact type, an ISO 14443 module is adopted instead of the IC module of the first embodiment. ISO 15693 can also be used as a substitute. In this case, an RFID antenna is necessary instead of using a contact terminal. This is easy to provide as wiring on the wiring board 11.

  The contents of the program are not as shown in FIG. 4, but as shown in FIG. 6, first, after performing anti-collision to identify which RFID, non-contact block reception is performed. If the authentication is successful, the lighting operation is performed. On the other hand, if the authentication cannot be obtained, the lighting operation is not performed. In either case, the authentication result is transmitted in a non-contact block, and a new non-contact block reception is accepted.

  In addition to the contact type, a method of repeating bulk reception, authentication work, lighting operation based on authentication, and BULK transmission after performing PnP processing as shown in FIG. 7 as a USB connection type is also possible.

  Further, a contact / non-contact / USB connection type is also possible, and all the functions of the first, second, and third embodiments are provided, and the determination work as shown in FIG. 8 is appropriately added. In this case, the non-contact operation uses the flowchart of FIG. 4 as a subroutine, the USB operation uses the flowchart of FIG. 6 as a subroutine, and the contact operation uses the flowchart of FIG. 7 as a subroutine. It is.

  In that case, when operating as a non-contact type, power is supplied from the antenna coil. When operating as a USB type, power is supplied from Vcc with both USB D + and D- signals. It depends on other power supply methods such as a battery.

  The present invention is a data carrier such as a data card such as a service card, a passport, a driver's license, and various data carriers that are portable mobile media that can be securely authenticated to a system that requires image authentication, such as high-end brand protection. It is applicable to.
