Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a portable electronic device, such as an IC card, which includes a data memory, a CPU, and the like.

[Technical background of the invention and its problems] Recently, in automatic transaction devices or home banking systems in financial institutions, IC cards having data memories whose stored data cannot be easily read due to data security are being used. (portable media) is being developed.

Conventionally, in systems for verifying a user's password using an IC card and a terminal, the following password verification system is known, and will be explained using FIG. 7. That is, I
A password is stored in the memory 42 of the C card 41. The user then inputs the password using the keyboard 44 of the terminal 43.

Then, the password is sent to the control unit 45 and the interface 46.
and is supplied to the CPU 48 via the interface 47. Thereby, the CPU 48 compares whether the password in the memory 42 and the supplied password match or not, and if they do not match (incorrect input), sends a mismatch (NG) signal to the terminal 43.
If the input matches (regular), match (OK)
The signal is output to the terminal 43, and the password stored in the memory 42 is not output to the outside at all.

However, although IC cards with such a password verification function are effective in terms of maintaining the confidentiality of information, depending on the use, entering the password may not necessarily be necessary.
IC cards, which require password verification, are inconvenient to use.

[Purpose of the Invention] This invention was made in view of the above circumstances, and its purpose is to provide a very convenient device that can be used for both applications that require password verification and applications that do not require password verification. Moreover, it is an object of the present invention to provide a portable electronic device whose price can be reduced by mass production.

[Summary of the Invention] This invention allows setting whether or not password verification is required at the time of issuance.

[Embodiment of the Invention] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, 1 is an IC card as a portable electronic device. The surface of this IC card 1 has a connection section 2.
For example, a plurality of terminals 21 . ...2
It is composed of 8. The terminal 21 is for operating power supply voltage (+5 V), the terminal 22 is for grounding, and the terminal 23 is for grounding.
is for clock signal, terminal 24 is for reset signal, terminal 2
5 to 2□ are for data input/output, and terminal 28 is for power supply voltage (+21 V) for data writing.

Also, inside the IC card 1, as shown in FIG.
unit) 3, a data memory 4 consisting of E2FROM or FROM, in which control programs, passwords/numbers (for example, 8 digits), data, etc. are recorded, an interface circuit 5, a RAM 6 for data processing, and a comparison circuit 7
It is made up of. Each of the above parts is composed of an IC chip and is provided on one substrate. Further, the interface circuit 5 and the connection section 2 are wired.

The memory unit 4 includes a password verification flag storage area 41 in which a flag indicating whether or not to perform password verification is stored, a password storage area 42 in which a password is stored, and a data area 43 in which data is stored. It is made up of. Further, the comparison circuit 7 operates when the flag is stored in the password verification flag storage area 41, and compares the password from the password storage area 42 with the password supplied from the CPU 3. Compare results to CPU3
This is what is output to. The CPU 3 has a built-in ROM section, and a control processing program is set in this ROM section at the time of issuance.

3 and 4 show the configuration of an IC card issuing machine 10 as a terminal according to the present invention. 11 is a CPU (central processing unit) that controls the whole; 12 is an input means for inputting data, such as a keyboard; 13 is a CRT display device; 14 is a ROM (read only memory) in which a control program is stored; 15 is a RAM (random access memory) in which data is stored; 16 is a dot printer that outputs continuous print data; and 17 is a floppy disk 19 inserted from a floppy disk insertion slot 18 for storing and reproducing data. The floppy disk device 20 is an IC card reading/writing section.

The IC card reading/writing unit 20 reads data in the memory of the IC card 1 inserted from the card insertion slot 21 or writes data into the memory, and is connected to the card issuing machine main body by a cable 22. It has become so.

That is, as shown in FIG. 5, a conveyance path 31 for conveying the IC card 1 inserted through the card insertion slot 21 is provided. The transport path 31 is provided with a plurality of pairs of rotatable transport rollers 32, which are positioned so as to sandwich the IC card 1 from above and below when transporting it. Each transport roller 32 provided in pairs is connected to the transport bus 3.
1 at equal intervals from each other. The distance from the center of each of these transport rollers 32 to the center of the adjacent transport roller 32 has the width dimension in the card transport direction. Therefore, the transport bus 31 for the IC card 1 is defined by the transport guide 33.

Further, the CP in the IC card 1 is placed on the transport guide 33.
A reader/writer 34 is arranged to exchange data with U3. This reader/writer 34 is electrically connected to the connector section 2.

In addition, the IC card handling machine 10' that performs password verification is also
It has the same configuration as the C card issuing machine 10. however,
The control programs in the ROM 14 are different.

Further, an example of an IC card handling machine that does not perform password verification is a card reader 50 installed at an amusement park or the like.
This subtracts the contents of the card. That is, as shown in FIG.
It is composed of an OM 53 and a RAM 54 for data storage. The IC card reading/writing unit 51 has the same configuration as the IC card reading/writing unit 20 described above.

Next, the issuance of an IC card in such a configuration will be explained. For example, now, the operator (issuer) sets the IC card issuing mode using the keyboard 12 of the IC card issuing machine 10 and inserts the IC card 1 into the card insertion slot 21. Then, the IC card reader/writer 34 and the connector 2 of the IC card 1 are electrically connected. As a result, the CPU 11 issues a message on the CRT display device 13 saying, ``Please specify whether or not to add a password verification function to the IC card to be issued.'' In response to this guidance, the operator uses the keyboard 12 to specify that the password verification function is not to be added. Then, the CPU
II provides guidance on the CRT display device 13, ``Please set the corresponding control program, data, etc.''. In response to this guidance, the operator inputs the control program, data (number of uses), etc. using the keyboard 12.

The signal corresponding to the above input and the signal indicating the issuing machine are CPUII
The data is supplied to the CPU 3 via the reader/writer 34, the connector 2, and the interface circuit 5. Then, C
The PU 3 stores the supplied control program in a ROM section (not shown) and stores the data in the data area 4 of the memory section 4.
Store in 3. At this time, since the function does not perform password verification, nothing is stored in the storage areas 41 and 42 of the memory unit 4. Then, the IC card 1 is issued from the card insertion slot 21.

Further, when specifying whether or not to add a password verification function, the operator uses the keyboard 12 to specify that the password verification function is to be added. Then, the CPU 11 issues a message on the CRT display device 13, saying, "Please enter your password." In response to this guidance, the operator inputs the password using the keyboard 12. A signal corresponding to this input and a signal indicating the issuing device are supplied from the CPU II to the CPU 3 via the reader/writer 34, the connecting section 2, and the interface circuit 5. Then, the CPU 3 stores the supplied password number Duram in the storage area 42 and causes the storage area 42 to store the password verification flag.

Next, the CPU 11 uses the CRT display device 13 to display "
Please set the corresponding control program, data, etc."
We will provide guidance. In response to this guidance, the operator inputs a control program, data, etc. using the keyboard 12.

A signal corresponding to this input is supplied from the CPU II to the CPU 3. Then, the CPU 3 stores the supplied control program in a ROM section (not shown) and stores the data in the data area 43 of the memory section 4. In this case, the first process of the control program is a password verification function. and,
The IC card 1 is issued from the card insertion slot 21.

Next, a case will be described in which a customer handles the IC card 1 to which the PIN number issued as described above is attached. That is, the customer inserts the IC card 1 into the card insertion slot 21 of the IC card handling machine 10''. Then, the IC
In the card 1, the reader/writer 34 and the connection section 2 of the IC card 1 are electrically connected. Next, CPU II
The CRT display device 13 prompts the user to "Please enter your password." In response to this guidance, the customer inputs his/her password using the keyboard 12. The signal corresponding to this input and the signal indicating the handling machine are CPUI 1 to C.
It is supplied to PU3. Then, the CPU 3 supplies the supplied password to the comparator circuit 7. At this time, the comparison circuit 7
is in an operable state due to the flag from the storage area 4□, and a password is supplied from the storage area 42. As a result, the comparison circuit 7 compares the password supplied from the CPU 3 and the password stored in the storage area 42, and transmits the comparison results, that is, a match signal and a mismatch signal, to the CPU 3.
Output to U3. Thereby, if the comparison result is a match, data can be accessed from the data area 43 of the memory section 4. Next, when a match signal is supplied, the CPU 1 determines that the passwords match, and displays a message on the CRT display device 13 saying, "Please input the handling data."

As a result, the user performs various handling processes. Also, C
When the PUII is supplied with a discrepancy signal, the CRT display device 13 displays a message saying, ``The password is incorrect, so please enter the correct password again.''

Further, a case will be described in which a customer handles an IC card 1 that is issued as described above and does not have a personal identification number attached to it. That is, the customer inserts the card into a card insertion slot (not shown) of a card reader (IC card handling machine that does not perform password verification) 50 installed at the amusement park. Then, in the IC card 1, the reader/writer 34 and the connecting section 2 of the IC card 1 are electrically connected. Then, the CPU 52 outputs a data read signal to the C'P U 3. Then, the CPU 3 reads the data (number of uses) from the data area 43 of the data section 4 and outputs it to the CPU 52. At this time, since the password verification flag is not stored in the storage area 41 of the memory section 4, the comparison circuit 7 is not activated. Thereby, the CPU 52 performs data subtraction processing and supplies the result to the CPU 3. As a result, C
PU3 stores new data supplied from CPU52 in data memory 4. Update the contents of. Next, IC card 1
is returned from the card insertion slot (not shown).

In the above embodiment, the verification of the password on the IC card was performed by the comparator circuit, but the verification is not limited to this, and the verification may be performed by the CPU.

[Effects of the Invention] As detailed above, the present invention can be used for both applications that require password verification and applications that do not require password verification, and is very convenient, and moreover, the cost can be reduced by mass production. It is possible to provide a portable electronic device that can measure
