Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an information processing device using a so-called IC (integrated circuit) card having, for example, a microcomputer, a memory, and the like.

[Technical background of the invention and its problems]

Recently, devices have been developed that use this type of IC card to perform automatic cash transactions, for example. In this type of device, first, an IC card is inserted into a terminal device installed in a company, and a password is entered using a key. are compared. As a result, if there is a match, operations such as depositing and withdrawing cash with the bank's processing equipment and inquiry of balance can be performed.

However, in the case of the above system, as long as the password code stored in the IC card and the password input by key match, it is possible to perform operations such as depositing and withdrawing cash. Therefore, there is a problem in that important tasks can be executed without obtaining approval from, for example, a superior.

[Purpose of the invention]

This invention has been made based on the above circumstances, and its purpose is to provide an information processing device that is capable of performing hierarchical approval at multiple stages depending on the content of work. .

[Summary of the invention]

This invention enables the memory of an IC card, for example, to
Memorize the first PIN code known to the person in charge of the card and the second PIN code known only to your superiors, and use not only the first PIN code but also the second PIN code when doing work that requires approval. The configuration is such that it cannot be executed unless the code is also entered by key and verified.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 and FIG. 2 show an information processing device. Inside the device main body 11 there is a device that controls the entire device.
CPU (Central Processing Unit)
12, ROM (read only memory) 13 in which control programs are stored, and RAM (random access memory) in which data is stored
14 are provided. The CPU 12 includes a keyboard 15 for inputting data, etc., and a keyboard 15 for displaying data, etc.
A CRT (cathode ray tube) display device 16, a floppy disk device 18 that stores and reproduces data using a floppy disk inserted from the disk insertion portion 17, and a memory of an IC card inserted from the card insertion portion 19. an IC card reading/writing device 20 that reads data and writes data into memory;
A printing device 21 for printing output data is provided.

Figure 3 shows an IC card.
An IC chip 32 is built into the card 31.
This IC chip 32 is used for control as shown in FIG.
The CPU (microcomputer) 41, control program, and data such as a first password known to the guardian (person in charge) of the IC card, and a second password known only to the superior are stored, for example.
It is composed of a memory section 42 constituted by E ² PROM, an interface section 43, and a connecting section 44 connected to a reading/writing section (not shown) provided inside the IC card reading/writing device 20. There is.

Next, the operation will be explained using FIG. 5.
First, in step _S1 , a person in charge who intends to execute a transaction using an IC card inserts the IC card 31
is inserted into the IC card reading/writing device 20, and the first password is input from the keyboard 15 in step _S2 . This input first password is transferred to the IC card ₃₁ in step S3.
That is, this password is sent to the CPU 12, the IC card reading/writing device 20, and the connection part 44 of the IC card 31.
The signal is supplied to the interface section 44 via.
In step _S4 , the CPU 41 of the IC card 31 reads out the first password from the memory section 42, and
In step _S5 , the read first password code is compared with the input first password code. This result is supplied to the CPU 12, for example
It is displayed on the CRT display device 16. If the two do not match, the control moves to step _S6 , and, for example, the process is stopped and terminated. on the other hand,
If the first passwords match, in step _S7 , business details such as cash withdrawals or cash withdrawals or balance checks are input from the keyboard 15. Thereafter, in step _S8 , the CPU 12 determines whether the input work content requires approval from the superior.
As a result, if the entered business content does not require approval, such as a low-value monetary transaction or balance verification, for example, a message to that effect is displayed on the CRT display device 16, and the corresponding business content is displayed in step _S9 . is executed. It is terminated after execution is completed.

Further, if it is determined in step _S8 that approval from the superior is required, a message to that effect is displayed on the CRT display device 16. The person in charge asks the superior who has the authority to approve the transaction to input the second password known only to the superior from the keyboard 15, as shown in step _S10 . This input second password is transferred to the IC card 31 in step _S11 as described above. I C
In the card 31, the second password is read out from the memory section 42 in step _S12 , and the second password is read out in step _S13.
The PIN code read out is compared with the PIN code transferred. This result is supplied to the CPU 12, and if the two do not match, control is transferred to step _S6 , and the process is stopped and terminated. Also,
If they match, the approval-requiring work is executed in step _S14 , and is terminated after the execution is completed.

According to the above embodiment, the first password code known to the person in charge of the IC card and the second password known only to the superior are stored in the memory section 42 of the IC card 31, and the important work requires the approval of the superior. In this case, the configuration is such that not only the first password code but also the second password code must be entered and verified. Therefore, hierarchical approval can be performed, and restrictions can be placed on the scope of work that can be performed by the person in charge of the IC card.

In the above embodiment, the number of password codes stored in the memory section 42 of the IC card 31 is two, but the number is not limited to this, and it is also possible to increase the number of approval stages by setting three or more password codes.

Furthermore, in consideration of confidentiality during input, a keyboard exclusively for the supervisor may be added, and this keyboard may be operated by the supervisor at hand.

It goes without saying that various other modifications can be made without departing from the gist of the invention.

〔Effect of the invention〕

As described above in detail, according to the present invention, it is possible to provide an information processing device that can perform multiple stages of approval depending on the content of the business.
