Description

[Detailed description of the invention] [Technical field of invention] This invention applies to specific equipment (for example, bank terminal equipment).

or an information processing device that handles important information).

[Prior art]

There are devices such as those mentioned above that can be operated by inserting a key or a plastic card (with a code recorded on a magnetic stripe), but all of these are simply Kinpo-manufactured devices. The code is recorded on the key or striped magnetic film using an encoder, making it easy to tamper with.In other words, a duplicate key can be easily created, and the above card uses a magnetic head to read the recorded contents to some extent instantly. and can be tampered with.

[Summary of the invention]

Therefore, the present invention proposes a method for operating a device, which is characterized by operating the device using an integrated circuit built-in card (hereinafter referred to as an XC built-in card) that is not easily tampered with. Explain in detail.

[Embodiments of the invention]

FIG. 1 is a diagram showing the relationship between the device, the card reader, and the operation control means, in which (1) is the device, and inside thereof, the hardware (2) is composed of the components C4 to C4. .

The hardware eye 2) is supplied with an operating signal (4) (including an operating power source) from the control means (3). (5) is a card reading signal generator.

(6) is a read signal and is given to the control means (3). (7
) is a card reader and is provided outside the device (1). P is a commercial power line.

In such a configuration, if a card (not shown) (distributed to a specific person such as an operator) is inserted into the card R taker (7), and the inserted card is a legitimate one, An output (41) is generated from the control means (3) and the hardware (2) is activated.

By the way, conventionally, as an identification medium, a plastic card provided with a magnetic stripe and a required code recorded on the stripe, or a key is generally widely used.

However, with conventional cards, the contents can be read out relatively easily by placing a magnetic head on the magnetic stripe, the card can be tampered with, and duplicate keys can be easily made. Furthermore, when the conventional card approaches a magnetic material, the recorded contents are erased and the card no longer functions as a specified identification card.

The present invention provides a method for operating a device that improves the above-mentioned problems, and will be described in detail below with reference to nine drawings.

Figure 2 shows a card (8) that plays an important role in this invention.
), and the feature of this card is that the sum product circuit Q (1 (J, , lT1C
That's what it means. ), and its IQ is connected to multiple input/output terminals fi11 including power supply and ground provided on the - side of the plastic plate (9) by a conductor (not shown) running inside the plastic plate. That's true.

That is, the above l0QI acts as an active element.

When a signal is applied from another device (not shown) through one of the input/output terminals (10), an output corresponding to the input signal is generated, and that output is transmitted through one of the input/output terminals aυ. This is what is output.

However, if a specific signal is given to 00[1.

You can get the corresponding output.

Therefore, the input
□If you specify how the output should be in relation to the force, you will be able to distinguish between individual cards.

Therefore, if such a card is given to a person authorized to operate a specific device, only that person can use the device, and the card cannot be easily tampered with. become.

FIG. 3 is a configuration diagram showing an example of the relationship between a card and a card reader, which is a feature of the present invention.

For convenience of explanation, an example will be described in which when one pulse is given to IQ, three pulses are generated at a predetermined interval (frequency).

FIG. 3 shows the relationship between the card reader (7) and the machine 0 (10). In the figure, the card reader (7) mainly includes a first signal circuit 02 and a second signal circuit OJ.

A power supply circuit 04 is provided, and a first circuit 04 outputs a predetermined pulse and receives a predetermined pulse generated from the IC of the card. In addition, the second circuit (131) has an identification function including a function (calendar identification function) (13a) for identifying the expiration date of the card, and also uses a signal generated from the IOQ to determine the authenticity and expiration date of the card (8). Judgment will be made accordingly.

In addition, f471 is a voice synthesis output device connected to the second circuit (131), and if the IC card is correct, it will output a message saying, ``I'm sorry.'' and convert it into voice through the speaker. This voice synthesis output device automatically switches modes, and if the card is incorrect, it outputs the message, ``You're out of luck.''

Power supply (b) line (141 is the power supply for the card reader itself, and also the power supply for flowing the new current to the coIn. It is the connector on the VaFi card reader side, and is the input/output terminal on the card side. It is equipped with an input/output terminal oo corresponding to the old). A predetermined pulse signal generated from the input/output terminal (168) and input to the N path 02 passes through the input/output terminal (168).
16P) is generated from the circuit 0, and the pulse signal input manually to the circuit 0(In) passes through.The input/output terminal (16ps) is for power supply, and (16F is the input/output terminal for grounding. .

These input/output terminals (16S), (16F), (16
pe), (16Fi) are the input/output ends (11s), (11p) of the card side contact terminal part an that engages with the connector O5.
), (11ps), and (11Fi) to exchange signals and supply power.

That is, by engaging the contact terminal portion 071 of the card (8) and the connector a9, the 0(In) of the card (8) can be made to function. (II is two inversion games)
A 1-bit memory circuit (Ql) in which (20a) and (20b) are cross-connected has two input terminals, one of which is supplied with the output pulse of the pulse generator (IS), and the other input terminal of the memory circuit (Ql). 19) The AND gate to which the output of (20b) is given is the flip-flop F.
It is a counter composed of 1 + '2, and is reset by the fourth input pulse, producing an output of 1, 2.3 if expressed in decimal. That is, three pulses occur.

Note that the T signal attached to Fl and F2 indicates a trigger input terminal, S indicates a set output terminal, and R indicates a reset input terminal. (C) is a decoder that inputs the output of a flip-flop, that is, the binary coded 1o advance number, and @ is an OR gate that inputs the output of the decoder, that is, the output corresponding to 1° base "11 "2""3". , and its output is given to the card reader through input/output terminals (11s) and (16B).

DM is a memory (for example, EEFROM: electrically erasable FROM) in which the expiration date of the card is electrically set and stored, and its contents are stored at the input/output terminal (11s) and the OR gate (
24+ and is given to the card reader before (or after) the output of the counter (c) through a timing gate G provided between the counter (c) and whether or not the card is within a predetermined validity period. will be judged.

In such a configuration, if the pulse generating circuit side is a self-oscillating type pulse generating circuit (such as a free running multi-channel circuit), an output pulse is generated when power is supplied.

Therefore, if one pulse is applied to the 1-bit memory circuit and the output of 1 inversion gate (20b) becomes 1'', then AN
A pulse train is output from the D gate (10)1. The pulses of this pulse train are also applied to the memory DM as a timing signal and counted by a counter, and when three pulses are output from the decoder, the counter is reset.

In more detail, the output of the decoder is decimal rlJ
Since the pulses are output corresponding to r2J and r3J, three pulses are generated according to the oscillation frequency of the pulse generating circuit and are applied to the card reader (7). The contents of the memory DM are also provided to the card reader (7) through the gate G.

Therefore, the card reader (7) reads l0Ql of the card (8).
detects that the card is working properly, thereby confirming that the card is the correct one. If the card is a fraudulent card, three output pulses will not be generated even if one input pulse is input, so that the card reader can know that a fraudulent card has been used. On the other hand, the expiration date identification function (
13a) determines whether the card is within its validity period.

By using an IC built-in card in this way, a device (1
) hardware (2) can now be controlled.

Moreover, it uses an IC, which is not easily tampered with.

Furthermore, since signals are exchanged in a mutual relationship with a card reader, there are no problems associated with conventional magnetic cards or keys.

Note that checking the validity period is to ensure the reliability of the card, and changing the card as appropriate and setting the validity period is an effective means to prevent card tampering.

Next, embodiments of this invention will be given and further explained.

FIG. 4 shows an example of the relationship between l0Ql and the card reader (7), in which synchronized pulses are generated from the pulse generator (C) of the IQI and the card reader (7), respectively.

Check the condition of the 1m1 period with the matching 1 (10) road bell of the signal circuit (c), and calculate the pulse that is the output of the matching 1 (10) road bell using the counting tr with preset function! Count with the J path (c), and when the counted value reaches the preset value, turn on the pulse generator (
The output of c) is stopped. Checking the synchronization pulse in this way helps in determining whether the card (8) is correct or not, and if a predetermined pulse output does not occur from the coincidence (b) path, the counting circuit will not step, and therefore the control means Output (4) will not occur from (3).

FIG. 5 shows another example in which a predetermined signal is applied to the IC (IQ) from the signal generating circuit ω of the card reader (7).

A corresponding signal is generated from the factory OQI and checked by the verification circuit c31) on the card reader (7) side, and if the verification result is correct, the signal 0 is sent to the IC (1 (l) and the factory
The output of the signal G is stopped, and the signal G can be used as a card confirmation signal.

FIG. 6 shows yet another example in which a predetermined signal is generated from the signal generating circuit ω of the card reader (7) and given to the machine 00I, and in response, a specific code signal ω is generated from the machine 0 (11). Generate it and give it to the matching circuit (goods).

This matching circuit (b) is given a registration code (to) recorded in the memory in the card reader (7), and (10). When (g) matches, an output (9) is produced and is applied to the control means (31) shown in FIG. 1 via the card reading signal generator (5).

FIG. 1 shows yet another example in which the two outputs of the matching circuit, C11, are applied to a lamp driver 14rI, which corresponds to a match or a mismatch in the matching FOU path. The lamp (
Either the lamp 41a) (for example, green) or the lamp (411)) (for example, red) is turned on.

That is, when the code signals (to) and (g) match, the lamp (41a) is lit at the output (to) to indicate that the device is OK to operate, whereas when the code signals do not match, the output (to) ), a lamp (41b)'i is lit to indicate that the operation cannot be performed.

FIG. 8 shows yet another example, in which, on the condition that two code signals (c) and (to) match in the matching circuit-1, the code signal generated from the engineering COI is recorded in the memory 0 and so on. This allows you to later find out which card holder operated the card.

FIG. 9 shows yet another example, in which the matching output of the matching circuit is counted by the counting 1PL path 143 to determine which code number the person who owns the card used the inquiring device.

Then, the counted value and code number are correlated with each other in the recording control circuit, and a memo +7 (recorded in 43 is set to 5, so look at the contents of memory @2 and see who activated the device and how many times. can be easily known.

Note that (49) is a display for checking the contents of the memory at any time, and an output device typified by a printer.

Figure 10 shows yet another example, in which it is possible to record which code number card was used to operate the visiting equipment, and the time signal generated from the 9 clock face and the code number (to). are associated with each other, and also through the memory 42.
It is recommended that you record it.

In this way, it is possible to easily know who operated the equipment during the visit.

Note that the IS in FIG. 10 is used in the same way as the output device (49) in FIG. 9.
