Abstract

PURPOSE:To prevent a foul transaction at a bank, etc. by using an IC built-in card (IC card) which is not altered easily with a limited number of using times. CONSTITUTION:When a single pulse is applied to an IC10 of an IC card 8, a pulse generating circuit 18 produces three pulses and applies them to a card reader 7. The reader 7 detects the correct actuation of the IC10 of the card 8 and then confirms a correct card 8. However three output pulses are not produced despite the input of a single pulse as long as the card 8 is not correct. Thus a foul card is decided. While an effective frequency discriminating function 13a checks the using times of the card 8. Then a transaction is discontinued if the card using times exceed a prescribed number.

Description

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

It relates to a method of operating an information processing device (such as an information processing device that handles certain important information).

[Prior art]

Conventionally, devices such as those described above can be operated by inserting a key or a plastic card (with a code recorded on a magnetic stripe). ? There are some that can make a voice, but they are not scary.Fl is simply a metal key or a stave-shaped magnetic film with a code recorded with an encoder, so it is easy to tamper with1.In other words, the key is easy. A duplicate key can be created for the card, and the recorded contents of the above-mentioned card can be read to a certain degree by the hour wheel using a magnetic head, and it can be tampered with.

Therefore, the present invention is characterized in that a device is operated using a card with a built-in integrated circuit (hereinafter referred to as a card with a built-in integrated circuit), which cannot be easily tampered with and can only be used a limited number of times. [Embodiment of the invention] Fig. 1 is a diagram showing the relationship between the equipment, the card reader, and the operation control means, which will be described in detail using the figures below. (1) is a device, the inside of which consists of hardware (2) made up of components C1 to C4. The hardware (2) is supplied with an actuation signal (4) (including an actuation 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 +31. (7
) is a card reader and is installed outside the device +11.
ing. P is a commercial power line.

In such a configuration, a card (not shown) (distributed to a specific person such as an operator) is inserted into the card reader (71), and if the inserted card is a legitimate one, the control means ( Output (4) is generated from 3) and hardware (2) is activated.

By the way, in the past, a plastic card provided with a magnetic stripe as an identification medium and a required code recorded on the stripe, or a key, have generally not been widely used.

However, with conventional cards, the contents can be read out relatively easily by applying a magnetic head to the magnetic stripe, and the card can be tampered with, and duplicate keys can be easily produced. Furthermore, when the conventional card comes close to a magnetic material, the recorded contents are erased, and the specified identification 1. It no longer functions as a +/- code.

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 one drawing.

Figure 2 shows a card (8) that plays an important role in this invention.
1, and the feature of this card is that the integrated circuit 01 (hereinafter referred to as "C") is built inside the plastic plate (9), and the integrated circuit CaQ is installed on the - side of the plastic plate (9). Multiple input/output terminals α including power and ground
υ and the conductor passing inside the plastic plate ([Yl not shown)
It means that they are connected by And this engineering C
The number of valid uses is preset in a1.

That is, the above IC+IQ acts as a counting element.

From another device (not shown) to any of the input/output terminals αD.
When a signal is applied through the input signal, it produces an output corresponding to the input signal and reduces the number of effective uses.
The output is outputted via either input/output terminal 011.

However, if a specific signal is given to OQl.

It is possible to obtain an output corresponding to that h.

Therefore, by specifying the type of output in response to input in each IC of each card, each card can be identified.

Therefore, if such a card is given to a person authorized to operate a specific device, only 2% of people can use the device, and the card cannot be tampered with easily. It turns out.

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 of ICHK is given, three pulses are generated at a predetermined interval (frequency).

FIG. 3 shows the relationship between the card reader (7) and the ICan. In the fan, the card reader (Ti id mainly has a first signal circuit (12) and a second signal circuit (0 countries).

11'f rIGj circuit I, the first circuit α
2 outputs a predetermined pulse and receives a predetermined pulse generated from the circuit C of the card. In addition, the second circuit 0 has a function (calendar identification function) (15) for identifying the number of valid uses of the card.
It has an identification function including a), and determines the authenticity of the card (8) and whether it has been used validly or not based on the signal generated from the device aα1.

In addition, (47) is a speech synthesis output device connected to the second circuit α-ken, and if the IC card is correct, it outputs "Douzon usashi teku dasai." and sends it through the speaker 0. This information is converted into voice and notified to the person attempting to operate the device. °Also. This voice synthesis output device automatically switches the mode and outputs ``If the card is not in the correct L position,''``You're in trouble.''

First, the power supply circuit α4 is a power supply for the card reader itself, and is also a power supply for supplying the required current to the IIG.

(Is is a connector on the card reader side, and includes an input/output terminal (IO) corresponding to the input/output terminal +I11 on the card side.The input/output terminal (16θ) is generated from the ICan.

And a predetermined pulse signal input to the circuit tlX5 passes.

The input/output terminal (16p) originates from the circuit α2 and is connected to ICQ (
The pulse signal input to I passes through. In addition, the input/output terminal (1
6pa) is for power supply, and (16') is an input/output terminal for grounding.

These input/output terminals (16th), (16p), (
16p8).

(16F) is the input/output terminal (1 sum) of the card side contact terminal L1η that engages with connector a9, (11p), (
111) 8”l and (11E) in contact with each other,
Sends and receives signals and supplies power.

That is, by engaging the card (contact terminal portion +17 of 81) and the connector α, the function CaI of the card (8) can be made to function. a & is a pulse generation circuit that generates pulses of a predetermined frequency, and 0g is two inversion gates (20a
) (20b) Cross-connected fc1 pit memory circuit, r
2υ is an AND operation in which the output pulse of the pulse generation circuit 0a is given to one of the two input terminals, and the output of one gate (201'I) of the memory circuit a value is given to the other input terminal. The gate (c) is a counter constructed from flip-flops F1 and F2, which is reset by the 4th input pulse, and is 1 if expressed in decimal.
．． 2. An output of 3 results. Namely.

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 receives the output of a flip-flop, that is, the binary coded decimal output;
! 41 is the output of the decoder, i.e. decimal rlJ r
It is an OR gate whose inputs are the outputs corresponding to 2J r3J, and the outputs thereof are fed to the card reader through the input/output terminals (11g>, (16B)) to be false.

]) M is a memory (for example, B
lr;FROM: A memory erasure type PROM) Teatte.

The contents are given to the card reader before (or after) the output of the counter through a timing gate G provided between the input/output terminal (11s) and the OR gate 041.

It is determined whether the card is valid for a predetermined number of times.

In such a configuration, an output pulse is generated at J when the pulse generating circuit α seconds is supplied with a self-oscillating type pulse generating circuit (for example, a free running multi-type circuit) and an electric decoration.

Therefore, when one pulse is applied to the 1-bit memory circuit H and the a''1 force of the 2 inverting gate (20b) becomes %1', a pulse train is output from the AND gate C1υ.The pulses of this pulse train are Memory DM as signal
The counter is counted by the counter, and when three pulses are output from the decoder (c), the counter is reset.

In more detail, the output of the decoder @ is decimal rJ
``2J [Because it is output corresponding to 3J.

Three pulses are generated according to the oscillation frequency of the pulse generating circuit (III) and given to the card reader (71).

The changed contents of the memory DM are also given to the card reader (7) through the gate 1.G.

Therefore, the card reader (71 is the engineering CQ of the card (8) [
Detects that the I has operated correctly, thereby confirming that the card is the correct one. If a fraudulent card is used and one input pulse is input, three output pulses will not be generated, so the card reader can know that a fraudulent card has been used. On the other hand, the valid number identification function (13a) determines whether the card has been used validly or not. By using the IC card in this way, the operation of the hardware (2) of the device (]) can be controlled. becomes possible.

Moreover, it uses an IC, which is not easy to tamper with.

Furthermore, signals are sent and received in a mutual relationship with the card reader.
Therefore, there are no problems like with conventional magnetic cards or keys.

Note that checking the number of valid uses is to ensure the reliability of the card, and changing the card as appropriate and resetting the number of valid uses is an effective means to prevent card tampering.

Next, some embodiments of this invention will be further explained.

Figure 4 is IC! In this embodiment regarding the relationship between fiI and card reader (7), synchronized pulses are generated from CaIII and the pulse generator (c) of card reader (7).

The state of synchronization is checked by the minus number circuit (5) of the signal circuit (A), and the pulses that are the output of the minus number circuit (5) are counted by the counting circuit (2) with a preset function, and the count value is preset. When the value is reached, a signal is sent to stop the output of the pulse generator (c). Checking the synchronization pulse in this way helps in determining whether the card (8) is correct or not, and if a predetermined pulse output is not generated from the - number circuit, the counting circuit will not step, and therefore the control means (3) will not advance. )
Therefore, output (4) will not occur.

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

A signal corresponding to the warpage is generated from the engineering CQI and checked by the verification circuit Gυ of the card reader (71ill). If the verification result is correct, the signal 03 is sent to the engineering Ca1 to stop the output of the engineering C. In this case, the signal Gz can be used as a card confirmation signal.

FIG. 6 shows yet another example, in which a predetermined signal is generated from the signal line 1 of the card reader (7) and given to the IC Cα1, and in response, a specific code 16 is sent from the ICati.
A signal (to) is generated and applied to the coincidence circuit C34).

This minus number circuit (goods) is given the registration code ■ recorded in the memory (15) in the card reader (7), and if (to) and (to) match, Output G
71 and applied to the control means (3) shown in FIG. 1 via the card reading signal generator (5).

FIG. 7 shows yet another example, in which the two outputs (to) of the -number circuit (2), G! 1 generates a signal corresponding to the match or mismatch in the lamp driver (4 (given to I and output from the matching circuit from the driver GIG) and outputs the lamp (41a) (green for 9L) and lamp (41b) (for example, red). ) lights up.

That is, when the code signal can and (to) match, the lamp (41a) is lit at the output (to) and the equipment is operated.
K is displayed, and if the code signals do not match, a lamp (41b) is lit at the output C31 to generate a sound indicating that the operation cannot be performed.

FIG. 8 shows yet another example, in which the code signal α generated from ICa (1) is transferred to the memory G115 on the condition that the two code signals (to) and c@ match in the minus number circuit (2).
This is to record information on the card so that it can be later determined which card holder operated the card.

FIG. 9 shows yet another example, in which the coincidence output of the coincidence circuit is counted by a counting circuit (43) to determine how many times the person who owns the card of which code number has used the device.

And the counted value and the code number are correlated with each other by the recording control circuit θ4 and recorded in the memory 02,
By looking at the contents of the memory (43), you can easily know who activated the device and how many times.

Note that (here) refers to a display for checking the contents of memory at any time, or an output device such as a printer.

Figure 10 shows yet another example, in which it is possible to record which code number card was used to operate the device and at what time.The time signal generated by the clock GIIE and the code number (to) can be recorded. are associated with each other, and are recorded in the memory (2) via -.

In this way, it is possible to easily know who operated the device and when.

Note that 09 in FIG. 10 is used in the same way as the output device (6) in FIG. 9.

[Effects of the Invention] As described above, according to the present invention, a specific device can be operated using a card that is not easily tampered with.
Therefore, troubles caused by operations by unspecified persons can be prevented.
