Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a card using a fingerprint for discrimination for identification, and a detection method for this card.

<Conventional technology and problems> Currently, cards with magnetic recording tape attached are used as identification means for banks and other institutions, but if the card is used by another person, the original identification will be disabled as long as the PIN number matches. will lose its meaning.

By the way, as is well known, the fingerprints of human fingers never grow, so every person's fingerprints are different, and the human identification ability is close to perfect.

Therefore, if this fingerprint is effectively utilized, it can be used as a means of distinguishing people.

Therefore, in order to provide true identification ability, if a fingerprint film is attached to the card and this fingerprint film can be matched with the card user's fingerprint, then the above problem can be solved.

<Object of the Invention> Therefore, an object of the present invention is to provide a card that can accurately identify a person using a fingerprint.

Another object of the present invention is to provide a card that can simultaneously perform the discrimination of a fingerprint film on a card provided with a fingerprint film and detect the fingerprint of a user's finger, and that can be added to a device for magnetically discriminating cards. The object of the present invention is to provide a detection method.

In other words, various types of cards have been issued that are used for identity verification, such as cards used in social life, including IC cards and LSI cards.

Cards that use VLSI, optical cards, and especially cards that use lasers are also considered.

Here, an IC card will be explained as one type of card.

In an IC card, a window or the like is provided on a card body to which a magnetic tape is attached, and a fingerprint-imprinted film protected by a transparent material is attached to the window or the like.

When the card is used, the card's fingerprint is compared with a pre-registered fingerprint to identify the card of the person in question, and by distinguishing between the user's fingerprint and the card's fingerprint,
Verify that the user is who he says he is. The detection method is to optically, electrically, or magnetically read the fingerprint-imprinted film surface of an IC card sent to a fixed position by a transfer means, and to detect a match with a stored signal of a fingerprint on the same fingerprint film that has been stored in advance by a discrimination circuit. It is then determined whether or not the card is the one of the person in question.

If there is no doubt that the card belongs to the person who is identifying the card, the card user presses the fingerprint suppression part that also serves as a push switch to create an image of the user's fingerprint on the screen.The image on the screen and the fingerprint on the fingerprint film are superimposed and electronic Scanning is performed by a group of probes, the output signal of the group of probes is discriminated by a discrimination circuit, and a one-shot multivibrator circuit is activated by the output signal from the discrimination circuit in which both fingerprints match, thereby achieving the purpose of using the card.

<Embodiments> Examples of the present invention will be described below with reference to FIGS. 1 to 4 of the accompanying drawings.
This will be explained based on the diagram.

1 and 2 show the structure of the IC card 11,
A window 14 is provided approximately in the center of the card body 13 to which a magnetic tape 12 having arbitrary sorting recorded information is attached.
4, a fingerprint film 15 which has been R-shaded in advance is stretched, and both sides of the fingerprint film 15 are covered with transparent protective layers 16.

The fingerprint film 15 is made of two positive films from which fingerprints can be clearly distinguished, one of which is fixed to the identification center and the other to the card body 13.

The detection method for identifying the IC card 11 can take various forms, but as shown in FIG. A reading device 19 for reading the fingerprint film 15 is provided at an arbitrary position.

This readout device 19 is configured in advance by, for example, transmitting light through the entire film and converting the amount of light passing through into an electrical amount and a magnetic amount, or converting it into a multi-digit electrical signal by moving a scanning probe. A discrimination circuit 20 identifies whether or not the films being recorded or stored match or do not match.

These operations are performed entirely using part of the circuitry of a conventional magnetic readout device, which is performed entirely by exchanging magnetic signals. It is not until a signal indicating that the card is the correct one is outputted by comparing the card's magnetic record and the fingerprint film that the card user identifies whether or not the card's fingerprint is compared.

As shown in the drawing, since the fingerprint of the relevant finger of the person concerned is held in advance as the fingerprint film 15 of the IC card, the film 15 is placed in front of the window 14 of the film 15
A screen 21 is arranged so that a fingerprint image having the same magnification as that shown in FIG.

In FIG. 4, 22 is a button made of a transparent material, 23 is a switching element that is turned on when the button 22 is pressed by a predetermined amount, 24 is a mirror, and 25 is a lens group.

The IC card 11 is held in a frame 26, and the frame 26 is attached with a moving mechanism 27 that moves left, right, up and down by a set amount. An electronic probe group 28 is arranged on the screen 21 in correspondence with the film, and the output of this probe group 28 is connected to a discrimination circuit 29.

Further, the output of the discrimination circuit 29 is connected to a one-shot multivibrator circuit 30.

That is, since the copper 22 for contacting the fingerprint also serves as a bush-type push button switch, the power circuit is turned on and the fingerprint is lightly pressed. Although the fingerprint pattern changes depending on the degree of suppression, the position of the pattern in the approximately central area is projected onto the screen at a constant position.

The fingerprint pattern projected on the screen is scanned by the moving mechanism 27 of the frame body to see if it matches the film 15 superimposed thereon, and an output signal corresponding to the set detection amount is output to the discrimination comparison circuit. It turns out.

<Effects> As described above, according to the present invention, card identification and card user identification can be performed simultaneously, and the device can be housed in a relatively small casing, so the circuit and power supply of a conventional card detector can be saved. Since it can be used and added easily, it can be used as an inexpensive and effective identification means.
