Description

DETAILED DESCRIPTION OF THE INVENTION (Al Industrial Field of Application) The present invention relates to an optical card system that executes operations such as transaction processing using an optical card that stores data using an optical recording method as a medium.

(b) Prior Art In conventional card systems whose main devices are automatic teller machines, door locks, etc., magnetic cards are generally used as a medium for causing the main device to perform operations. This magnetic card has a PIN number set in advance by the card owner magnetically recorded on it, and when the main device performs operations such as transaction processing, unlocking, and locking, the user inserts the magnetic card into the card reader. Insert it and enter your PIN. The main device compares the password stored in the magnetic card with the number input by the user to confirm that they match. In this way, by executing the operation only when the entered number matches the PIN number stored in the magnetic card, the operation of the main device is not performed by anyone other than the cardholder. That's what I do.

(C) Problems to be Solved by the Invention However, in conventional card systems using magnetic cards, the decision as to whether or not to execute the operation of the main device was made only by checking the PIN number. If someone other than the card holder finds out about the card in this way, even someone other than the card holder will be able to operate the main device through the stolen magnetic card. I couldn't do it.

Additionally, in order to prevent misuse by others, if the entered number does not match the PIN stored on the magnetic card for a specified number of consecutive times, the magnetic card will no longer be usable. Some did. However, there are cases where the cardholder makes a mistake in keystrokes when entering the number, or does not remember or forget the PIN number correctly.
Even in such cases, if the number entered does not match the PIN number for a predetermined number of times in a row, the card becomes unusable and the main device does not operate even though the card owner is using the card. You will not be able to do it.

The purpose of this invention is to reliably prevent the main device from operating due to operation by a person other than the card holder by verifying human body information data unique to the cardholder before operating the main device. To provide an optical card system that allows any owner to operate a main device.

Means for Solving the ld1 Problem The optical card system of the present invention includes an optical card storing human body information data specific to a cardholder, an information reading means for reading the human body information data from the optical card, and a cardholder's body information data. and a collation means for collating the human body information data read by the information reading means with the human body information data input from the information input means,
A main device that executes a processing operation when both pieces of human body information data match in the matching means;

That is, as shown in FIG. 1, the main device includes a human body information reading section, a human body information input section, and a collation section. The human body information reading section reads data written on the optical card and supplies it to the collation section as card information data. The collation section collates this card information data with the human body information data inputted from the human body information input section, and the processing operation control section enables or disables the processing operation depending on whether the two match or do not match.

<e) Effect In the present invention, the processing operation of the main device is executed only when the human body information read from the optical card by the human body information reading means and the human body information input from the human body information input means match. The human body information collated here is unique to the card owner, and the human body information written on the optical card matches only the body information data of the card owner.

Therefore, even if a person other than the cardholder inputs human body information data into the human body information input means, the main device will not perform any processing operation, and if the cardholder inputs human body information data from the human body information input means.ヰ always executes the processing operation.

Tf) Embodiment FIG. 2 is a plan view including a partially enlarged view of an optical card forming a part of an optical card system which is an embodiment of the present invention.

The optical card 1 uses a material commonly used as a card base material, such as polyvinyl chloride or polycarbonate, as a base material. Optical card 1 points to the card reader (not shown) with arrow A.
inserted in the direction. An optical recording section 2 is formed on a portion of the surface of the optical card 1. Tracking guides 3 are formed in the optical recording section 2 at minute intervals in the insertion direction, and pits 4 are formed according to the tracking guides 3 by a known optical recording method, and storage data is recorded.

FIG. 3 is a block diagram showing the main parts of the main device forming a part of the optical card system.

The optical card 1 is inserted into the card reader 1) through the opening 19. This card reader 1) is a human body information reading section shown in FIG. The optical card 1 inserted into the card reader 1) is transported at a constant speed in the direction of arrow A via the card holder 15 by a card transport mechanism 18 including a motor M2. A guide shaft 14 is provided inside the card reader 1) in a direction perpendicular to the card transport direction, and a guide 13 on which an optical head 12 is mounted connects this guide shaft 14 to the drive force of a head drive mechanism including a motor M1. Receive and slide. That is, the optical radar 12 reciprocates in a direction perpendicular to the transport direction of the optical card 1 (in the direction of arrows C and D).

The main device is equipped with a fingerprint reader 21. This fingerprint reading device 21 is a human body information input section shown in FIG.
The fingerprint of the finger placed on the placing section 22 is imaged by the CCD camera 23 via the mirror 24. The placing unit 22 is equipped with a switch SWI, and whether or not a finger is placed is detected by turning on/off the switch SWI.

The ON data of the switch SWI is inputted from the I10 interface 32 to the CPU 31 constituting the processing operation control section shown in FIG. Further, the card data read by the optical head 12 is input to the CPU 31 via the amplifier 36 and the signal processing section 35. Image data captured by the CCD camera 23 is stored in the V-RAM 33 via an A/D converter 34.

Further, the CP[J31 outputs control data for the semiconductor laser included in the optical head 12 to the laser driving section 37. The optical head 12 irradiates the optical recording section 2 of the optical card 1 with laser light from this semiconductor laser, and determines the presence or absence of a pit 4 shown in FIG. 4 by deflecting the reflected light. Image data of the fingerprint of the card owner is stored in the optical card 1 through pits 4, and by knowing the configuration of the pits 4, the fingerprint of the card owner can be read out as human body information data.

FIG. 4 is a flowchart showing a part of the processing procedure of the control section of the main device.

When the optical card 1 is inserted, semiconductor laser drive data is output to the laser drive unit 37 to start reading the card data (nl, n2), and a display prompting the user to place their finger on the placement unit 22 is displayed. (n3). When a finger is placed on the placing section 22 and the switch SW1 is turned on, reading of image data is started (n4→n5). The card data read by the card reader 1) is sent to the RA connected to the CPU 31.
The image data of the fingerprint stored in M38 and read by the fingerprint reading device 21 is stored in the V-RAM 33.

When the reading of the card data written in the optical card 1 and the reading of the imaging data are completed, the CPU 31 reads the imaging data stored in the RAM 33 and the imaging data stored in the RAM 3.
Check the card data stored in 8 (n6
). This n6 is the processing of the matching section shown in FIG. As a result of this comparison, if the two match, it is displayed that the fingerprint confirmation has been completed (n7→n8), and the device operation mode is executed to process the selected content (n9.n1O).

When this processing operation is completed, the card is released (n1) →
n12).

If the image data stored in the V-RAM 33 and the card data stored in the RAM 38 do not match in nl, a message indicating that the fingerprint could not be confirmed is displayed and the optical card 1 is ejected (nl → n 13 → n 12)
.

As described above, according to this embodiment, the main device operates only when the fingerprint of the finger placed on the placement section 22 matches the fingerprint stored as image data on the optical card 1. is executed. Therefore, the cardholder can always cause the main device to perform processing operations without setting, memorizing, or inputting a PIN number, and the use of the optical card 1 by others can be reliably excluded. In this example, fingerprints were used as human body information, but in addition to this, the state of capillaries in the retina of the eyeball, voice prints,
Characteristics unique to the cardholder, such as palm prints and facial features, can be used as human body information. In this case, a device capable of reading each human body information is provided in place of the fingerprint reading device of this embodiment.

In addition, in this embodiment, the optical head 1 is
2 is moved back and forth in a direction perpendicular to the insertion direction of the optical card 1, but the data stored in the optical card may also be read by a plurality of optical heads mounted on a rotating plate. In this case, the tracking line in the optical card is formed in an arc shape in accordance with the trajectory of the optical head.

fg1 Effects of the Invention According to this invention, a PIN number is not required to confirm the cardholder, the cardholder does not need to set, memorize, or input a PIN number, and the cardholder's unique human body information is used to identify the cardholder. This has the advantage of allowing the main device to execute processing operations, and even if the optical card is stolen, the processing operations will not be executed by anyone other than the card holder, improving reliability and security. be.
