Abstract

PURPOSE:To decrease an opportunity in which an IC card is used in an unauthorized manner and to improve security by ejecting the IC card from a data processor when the data processor receives a receiving power source supplying operation signal under a state in which the IC card cannot be taken out from an external part. CONSTITUTION:When an IC card 10 is inserted into the entrance of an IC card read and write device 13, an IC card taking in/ejecting processor 104 sucks the IC card 10 into the IC card read and write device 13 and guides the IC card 10 up to a prescribed position terminal contact position, the edge of the IC card 10 enters the internal part of the IC card read and write device 13, and the IC card 10 is made into a taking out impossible state. Further, at a point where the execution of prescribed processing completes, a CPU 12 sends a control signal for ejecting the IC card through a control line 102 and ejects the IC card 10 inserted into the IC card read and write device 13 by the IC card taking in/ejecting processor 104. Thus, the opportunity in which the IC card is pirated can be decreased, and security for data can be improved.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an IC card data processing system, and more specifically, an IC card data processing system that can prevent theft, unauthorized use, etc. of an IC card. Regarding.

[Prior Art] In financial institutions such as banks, a large number of terminal devices are placed inside the store, and these terminal devices are connected to a large central computer via public telephone lines, and these terminals are used to deposit, withdraw, transfer money, and inquire about savings balances. , and various business processes such as the transfer of funds through transfers, transfers, etc. are performed. The terminal devices used in this case are generally terminal devices using personal computers for R, and floppy disks are often used as external storage devices.

[Problem to be solved] Can floppy disks be easily accessed from terminal devices? Terminal devices using general-purpose personal computers are easy to handle data because they can use data created by other terminal devices and anyone can access the information on the terminal device. The drawback is that there is a large possibility of unauthorized use.

On the other hand, a data processing system using an IC card can be said to have higher data security than a floppy disk in that the data inside the IC card can be accessed using a personal identification number as a key. However, I
When the C-card falls into the hands of another person, there is a high possibility that the password will be decrypted and returned for unauthorized use.

In particular, when using an IC card in a terminal device, etc.
There are 7 systems that are equipped with an automatic ejection mechanism to prevent people from forgetting to remove the IC card, but in such cases, the IC card may be ejected carelessly when the power is cut off, etc.
When a power outage or the like occurs, there are many opportunities for IC cards to be stolen, and data security inevitably deteriorates.

This invention solves the problems of the prior art, and
An object of the present invention is to provide an IC card data processing system in which a C card is difficult to be stolen.

[Means for Solving the Problems] The configuration of the IC card data processing system of the present invention to achieve the above object includes an IC card and a data processing system to which the IC card is attached and which exchanges information with the IC card. In an IC card data processing system having an IC card data processing device, the data processing device is equipped with an IC card import/exit processing mechanism, and when an IC card is inserted, the data processing device receives an
A C card is received in a state that it cannot be removed from the outside, and when the data processing device receives a power-on operation signal, the accepted IC card is ejected by an IC card import/eject processing mechanism.

[Operation] In this way, the data processing device accepts the IC card in a state where it cannot be removed from the outside, so when the IC card is installed, the IC card is sucked into the IC card reader/writer and cannot be removed from the outside. This improves security and allows the IC card to be ejected from the device when it receives a power-on operation signal.
If the power to the data processing device is cut off due to a power outage or is suddenly turned off during data processing, the I/O
There is no need to eject the C card, and the IC card is kept inside the data processing device, so you cannot give it to someone you don't know.
No cards will be taken out.

As a result, the chances of the IC card being used inappropriately are reduced, and the security of the device using the IC card can be improved.

[Embodiments] Below, embodiments of the present invention will be described in detail with reference to the drawings.

In FIG. 1, ■ is a data processing device that is used with an IC card 10 and a memory card 11 installed, and is connected to a central host computer (not shown) via a modem, line, etc. Exchanges data with the host computer.

The data processing device l includes a microprocessor (CPU) 1
2, and the CPU 12 has an I
C card reader/writer 13, memory card connector 14
, a RAM (Random Access Memory) 15, a ROM (Read Only Memory) 16, a display 17, a keyboard 18, and a printer 19, respectively.
Data is exchanged with these circuits, and the IC card 10 via the IC card reader/writer 13 and the memory card 1 via the memory card connector 14.
1 and 1 respectively.

The bus 101 is provided with a data bus, an address bus, and a control bus, and the RAM 15 stores an application processing program for processing and data to be described later, and is backed up by a battery 151. . Further, the ROM 1B stores a control processing program and a basic processing program for controlling hardware and the like.

Here, the display 17 is controlled by the CPU 12 to display data processing results and operation messages for the operator who operates the data processing device l, and the printer 19 is controlled by the CPU 12.
Under the control of the PU 12, output of predetermined processing results, etc. is performed.

Execution of predetermined data processing and input of various types of information by the data processing device 1 are performed by the operator from the keyboard 18, and the CPU 12 interprets the inputted information and executes various types of processing.

20 is an IC card loading/unloading processing mechanism consisting of an IC card transport mechanism and its driving mechanism;
Control lines 102, 10 connected to the control bus 1
3, the IC card IO is controlled by the data processing device 1
Carrying it into the interior or discharging it from the interior to the exterior.

The RAM 15 stores various processing programs and card confirmation data for the IC card IO, and these are loaded onto the memory card 11 (program card IO) by the CPU 12 according to the program load processing program stored in the ROMIEJ. ) to RA
It was previously read into M15 and transferred.

The memory card 11 is specifically composed of two types of cards, one of which is a program card that stores the various processing programs described in 1- above, and the other is a data card that stores processing data. . These memory cards 1
1 is selectively attached to the data processing device 1 via the memory card connector 14 for use.

The IC card 10 includes a microprocessor, a ROM that stores various basic processing programs, an application processing program, or an electrically programmable and erasable nonvolatile memory (EEPROM) that stores various data.
It consists of Atsushi, IC card reader writer 13
is attached to the CP via the IC card reader/writer 13.
Exchange information with U 12. In addition, the ROM of the IC card 10 stores a determination processing program that determines whether the PIN number is correct or does not match.
M stores card identification information for confirming the validity of the card and card management information as second confirmation information.

This tC card 10 is used by being attached to the data processing device 1, and the IC card IO attached to the device is taken into the IC card reader/writer 13, as shown in FIG. The lid of the IC card insertion [131] is closed except when the IC card 10 is inserted, and even if the lid is opened, the IC card 10 inserted inside cannot be taken out. . Alternatively, the structure may be such that there is no lid and the IC card 10 cannot be taken out. The IC card IO sucked into the IC card reader/writer 13 can be taken out only by driving the IC card take-in/discharge processor side 20.

The IC card loading/unloading processing mechanism 20 is provided inside the IC card reader/writer 13 and detects the IC card 10 inserted from the IC card insertion slot 31.
It operates and guides the IC card 10 to a predetermined terminal contact position located at the back of the IC card insertion [131] of the IC card reader/writer 13.

At this IC card taking-in position, as shown by the dotted line in FIG. 3, the edge near the outside of the IC card 10 penetrates into the inside, making it impossible to grab the IC card IO from the outside. In addition, 32 is a memory card insertion L1, and the memory card connector 14 is arranged at the back thereof.

In such a configuration, the operation is as follows. That is, in step 21, when a power switch (not shown) is turned on, the data processing device 1 that has received the power-on signal first turns on the CP in the next step 22.
U12 uses the processing program in ROM1B to initialize internal registers, keyboard 18, printer 19,
The display 17 is initialized. Thereafter, in step 23, the IC card loading/unloading processing mechanism 20 is operated to perform IC card loading/unloading processing. Such processing is
This is done by the CPU 12 sending a control signal to eject the IC card IO to the side 20 of the IC card intake/ejection processing machine via the control signal line 102. >: When receiving 102, the IC card 10 is ejected, and the IC card 10 is ejected from the IC card reader/writer 13.

Depending on the timing when the IC card 10 is correctly ejected, the data processing program in the RAM 15 is activated in step 24, and the CPU 12 displays the display 17.
A message to insert the IC card 10 into the IC card reader/writer 13 is displayed. In this case, the data card (
When one of the memory cards 11 (hereinafter referred to as data card 11) is not attached to the memory card connector 14, a message to that effect is also displayed. And I.C.
A loop is entered waiting for detection of card 10 attachment. When the data card 11 is not installed, a loop is also entered to wait for its detection.

The IC card IO is sent to the IC card reader/writer 13 by a person [1
When the IC is inserted into the IC, the CPU 12 transmits the detection signal to the IC.
Control signal line 103 received from card reader/writer 13
IC card 10 via IC card reader/writer 13
A command to import the IC card into the IC card is sent to the IC card import/eject processing mechanism 20.

The IC card loading/discharging processing mechanism 20
0 into the IC card reader/writer 13 and guide it to a predetermined position end r contact position. As a result, the edge of the IC card 10 gets inside the IC card 10 as shown in FIG.
The card 10 becomes unable to be removed.

If data card 11 is installed and IC card 1
0 is attached to the IC card reader/writer 13, the CPU 12 detecting it starts the confirmation information check processing program in the RAM 15, and in the next step 24, the CPU 12 starts the confirmation information check processing program in the RAM 15.
The card identification information and card management information specific to the card are read from the C card 10, the W validity of the IC card is checked based on these confirmation information, and a predetermined process specified by the operator via the keyboard 18 is executed. Execute.

Then, when the execution of the predetermined process is completed, in step 25, the CPU 12 sends a control signal to output the IC card rJ via the control line 102 by a command from the keyboard 18 or automatically. The IC card loading/unloading processing mechanism 20 performs a process of ejecting the IC card 10 inserted into the IC card reader/writer 13. Note that an alarm can be generated to prompt the operator to receive the IC card 10 at the time of ejection.

Therefore, under normal processing conditions, unless the IC card 1O taken out from the -rj data processing device 1 is left somewhere, it will not be stolen or lost.

In this way, when the processing of the data processing program is completed normally, the IC card 10 is sent via the control signal line 102.
However, if the power is cut off before the processing by the data processing program is completed, step 14a is performed.

24b, the CPU 12 does not send a signal to the IC card reader/writer 13 to eject the IC card 10, but keeps the IC card 10 sucked into the IC card reader/writer 13.

As a result, even if a "1" failure such as a power outage occurs while the operator is away from the data processing device during data processing, or even if the power is cut off by someone else, the I/O
Since the C card 10 is not ejected from the IC card reader/writer 13, the IC card 10 is never removed. Furthermore, when the power is turned on, the IC card 1O that has been sucked into the IC card reader/writer 13 is ejected, so that accidents such as forgetting to put it down will not occur.

As explained above, the IC card ejection process when the power is turned on first detects whether or not an IC card is installed inside the IC card reader/writer, and when it is detected that the IC card is installed. Alternatively, a process may be performed to eject the IC card from the IC card reader/writer.

[Effects of the Invention] As can be understood from the explanation in 1-1- above, according to the present invention, the data processing device accepts the IC card without being able to take it out from the outside, so when the IC card is installed,
When the IC card is sucked into the IC card IJ and cannot be removed from the outside, its security is compromised.
Since the IC card is ejected from the device, there is no need to eject the IC card when the power to the data processing device is cut off due to a power outage or is forcibly turned off during data processing. Since the IC card is kept inside the data processing device, there is no possibility that the IC card will be taken out by an unknown person.

As a result, the chances of the IC card being used illegally are reduced, and the security of the device using the IC card can be improved 1-1.
