Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field to which the Invention Pertains] The present invention relates to a verification function system that verifies input data such as passwords input from a plurality of terminal devices at a master station.

[Prior art and its problems]

Conventionally, in this type of system, the following methods have generally been employed to verify data input from a terminal device.

In other words, all collation tables that store the data to be collated are stored in advance in a memory such as a floppy disk with a relatively large storage capacity, and data is sequentially retrieved from the memory of the floppy disk only when a collation request is received from the terminal. It is a means of transferring and collating information. but,
This method has the following disadvantages because it takes too much time to access the memory of a floppy disk or the like.

For example, a terminal device sends a verification request based on the input data and waits for the verification result from the master station, but if verification takes time, the usage efficiency will be reduced and the service will be degraded. Furthermore, if the verification time takes longer than expected,
There was a time when the user believed that the terminal device was broken and hit the terminal device, and in the worst case scenario, the terminal device might be damaged.

Therefore, in order to reduce the verification time mentioned above as much as possible,
A method has been proposed in which all collation tables can be accessed at high speed, for example, by storing them all in an IC memory. −
However, although this method reduces the matching time, it requires the use of a large amount of relatively small memory, which makes the entire system expensive and increases manufacturing costs. was there.

Furthermore, a method has also been adopted in which verification data is stored in advance in a portable storage means such as a magnetic card, and the verification data is compared with the input data inputted from a terminal device. However, with this method, the verification data is stored on a card such as a magnetic card, so if the card is lost or stolen, there is a risk that the verification data on the card could be read by someone else. The disadvantage is that there is a risk of it being used.

[Purpose of the invention]

SUMMARY OF THE INVENTION In view of the above-mentioned points, an object of the present invention is to provide an inexpensive verification function system that can perform complete verification in a short period of time.

[Key points of the invention]

In order to achieve such an objective, the present invention stores and stores collation tables in a relatively small-capacity main memory that can be accessed at high speed and a relatively large-capacity auxiliary memory, depending on the frequency of use. By storing frequently used comparison tables in the former high-speed main memory, the comparison time can be shortened.

[Embodiments of the invention]

Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an example of the configuration of the verification function system of the present invention,
Here, l is a plurality of terminal devices such as automatic cash dispensers that make data verification requests based on input data, and 2 is a terminal device/ that verifies the data input from the table with a table described later and determines whether the verification is correct or not. A master station 3 is an electronic computer system that is connected to the master station via a transmission line and exchanges various data.

The master station 2 has a relatively small-capacity main memory M/ that can be accessed at high speed, and has a part of a verification table storing verification data such as correct passwords stored in the main memory M/ in advance. The electronic subtraction machine system 3 has an auxiliary memory M2 which has a larger capacity than the main memo +) M/ of the master station λ but is accessed at a slower speed. is stored in advance in the auxiliary memo IJM.

Therefore, only a certain amount of matching tables can be stored in the main memory M/ of the master station λ. Therefore, when the terminal 1 is used as an automatic cash dispensing machine used in a bank, for example, in order to speed up the verification time for special customers at a certain branch, the verification data is stored in the main memory of the master station 2. The verification data of customers at other branches will be stored in the auxiliary memory I of the computer system 3. In this way, the collation table that is likely to be used frequently can be accessed at high speed in the memo on the master station 2 +) M
Store it in /.

Next, an example of the operation of the verification function system of the present invention shown in FIG. 1 will be explained with reference to the flowchart shown in FIG.

Based on the data input by the user from the terminal device IA, a data verification request is sent from the terminal i/A to the master station 2 (see steps S/ and Sλ). Upon receiving this verification request, the master station 2 searches for the same data as the data input from the terminal W/A in the verification table in its own memory M/ (see step S3).
If there is identical data, immediately send a verification result indicating that to the terminal/A (see steps SII and Sj).
. In this way, if the verification data corresponding to the input data is stored in the memory M/ of the master station which can be accessed at high speed, the verification can be performed in an extremely short time.

On the other hand, if the data input by the user from the terminal device /A does not exist in the verification table in the memory M/ of the master station λ, the master station λ temporarily holds the verification result for the terminal device /A. At the same time, a verification request is sent to the computer system 3 via the transmission line l (step s).
II and S6).

The computer system 3 searches whether the same data as the verification request data from the master station 2 exists in the verification table of its own memory M2, and sends the result to the master station 2 (
See steps $7 and sr).

The master station λ, which has received the verification result from the computer system 3, notifies the terminal device/A of the verification result.

On the other hand, when the terminal device/A receives a t# notification from the master station to temporarily suspend the verification results, it uses some method, such as screen display or audio, until the verification results are sent. It is possible to notify the user that the data is being compared through a display, etc., so that the user can
It is possible to prevent the terminal device/A from being hit due to a premature diagnosis of a failure of A or the system. Furthermore, the terminal device/A can also do other work during the waiting time for the verification result from the master station 2.

If there is a matching result that the data match, then there are various operations such as sending and receiving data between the user and the terminal/A, but the explanation of these operations is not directly related to the present invention. Since there is none, I will omit it.

FIG. 3 shows an embodiment in which the present invention is applied to a vending machine, where j is a magnetic card type vending machine in which products can be purchased via a magnetic card as a terminal, and It is a transmission controller as a station.

The transmission controller 6 has a relatively small-capacity memory M3 that can be accessed at high speed, and the memo I) Mj stores, for example, a collation table for frequently used passwords for 100 people, with t bytes for 7 people. Store it in advance. In addition to data verification control, the transmission controller 6 also performs various controls such as starting and ending transmission between the magnetic card type vending machine and the transmission line.

The electronic computer system 3 has a relatively large storage capacity.

It has a floppy disk Mll as a large memory,
The floppy disk 1 stores in advance a password verification table for 100 people, for example, which is used relatively infrequently and cannot be stored in the memory M3 of the transmission controller 2.

In this configuration, when the user inserts a magnetic card into the card slot of the magnetic card vending machine sh and enters the PIN number, the magnetic card vending machine H sends a message to the transmission controller B. A verification request is issued.

The transmission controller 6 compares and verifies the input data (PIN number) with the collation table for 100 people. As a result, if there is data (PIN number) that matches the input data, the transmission controller t immediately replies to the magnetic card type vending machine rA with the verification result.

Since this verification processing time is approximately 1 second or less at maximum, it is a fully satisfactory service for users of the magnetic card type vending machine 5A.

On the other hand, if the PIN entered by the user does not match the PIN in the verification table of the transmission controller 6, the transmission controller 6 sends information to the magnetic card vending machine SA to temporarily suspend the verification results. At the same time, a verification request is sent to the computer system 3 via the transmission line l. '' In response to this verification request, the computer system 3 calls a verification table for 10,000 people from the floppy disk l, compares and verifies this verification table with the input data, and transmits the results to the transmission controller 6 via the transmission line.
Send to. The transmission controller 6 that receives the verification result from the computer system 3 transmits the result to the magnetic card type vending machine H. This series of processing time is greatly influenced by the processing speed of the computer system 3,
The verification processing time described above will also take much longer.

On the other hand, the magnetic card vending machine tA, which has received information from the transmission controller t that the verification results will be temporarily suspended, is verifying the PIN number for the user during the above-mentioned series of processing times. For example, a message such as "Please wait for a while while the password is being verified" is displayed on the screen or in voice.

In addition, while the display is displayed, the magnetic card type vending machine tA is
Other processing can be performed. Furthermore, this display allows the user to confirm that the magnetic card type vending machine 5A or the system is operating, so that the user can wait without being bothered for a predetermined period of time until the verification of the password is completed.

In addition, although the above-mentioned embodiment shows an example in which a magnetic card type vending machine is applied as a terminal device, the present invention is not limited to this, and the present invention can also be used simply to determine the validity/invalidity of a magnetic card or input data. can.

For example, the same card can be valid and invalidated depending on the time of day, for example, during the day and at night, so it can be used not only for magnetic card PIN numbers but also for verifying ownership information of so-called ID cards. can.

〔Effect of the invention〕

As explained above, according to the present invention, the collation table is divided into a small-capacity memory that can be driven at high speed and a floppy disk that is a slow-speed but large-capacity memory, and the frequently used collation table is stored in the former. Since the data is stored in a high-speed memory, it is possible to provide a system capable of collating data in a short time at a relatively low cost.

Further, according to the present invention, when the matching time becomes long,
Since the master station sends information to the terminal to the effect that verification is currently in progress and displays a message to that effect on the screen, the terminal can not only perform other processing until verification is completed, but also be able to use This has the advantage that the person can recognize that the entire system is operating correctly and can wait for the verification to finish without getting frustrated.
