Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for judging the suitability of a data entry person by using a card formed with a magnetic body.

[0002]

2. Description of the Related Art Personal information is input by using a card formed with a magnetic body in which predetermined data is written in advance and passing through a magnetic card reading means. A system has been generalized in which an output unit gives permission to pass a reception and a data change input is permitted to allow access to a microcomputer device by defining an owner.

[0003] The feature of this system is that data can be input by a magnetic body of the card, so that necessary personal information is written on the magnetic body, and it is not necessary or necessary to store personal information in the system. You can do it. However, on the premise that the card is owned and operated by the person, the output means gives permission to pass the reception and enables access to the microcomputer, so that the person who passed the card There is no assurance that you are who you are, for example, a person who picks up a card can easily impersonate you if you use it incorrectly.

[0004] Therefore, in order to cope with such unauthorized use in a simple manner without referring to the personal information stored in the system, a numerical data input means is provided in parallel with the magnetic card reading means to use the system. When a password common to only the user group is determined, personal information is read by the magnetic card reading means, and a password consisting of, for example, four digits is input to the numerical data input means, when the input data matches the password, the output means If you give permission to pass, you can reject third parties who have picked up the card without putting a heavy burden on the system.

[0005]

As described above, if the read data from the card is used in combination with the common password that is valid only for a friend, the card cannot be used even if a person other than the friend picks up the card. , Increase safety.
However, since the password is the same, if the person who picked up the card got a common password from other people,
Get permission to go through the reception on behalf of the card holder,
Since it becomes possible to access a microcomputer device or the like, it has been basically difficult to increase the safety by this method.

[0006] Therefore, in order to prevent unauthorized use of the card on which the magnetic material is formed, the input person is required to determine a unique password, and this password is hidden in the data written on the magnetic material of the card. There is a method, but this method is not a good way to understand the password by analyzing the magnetic material. Eventually, a method is generally used in which a password is stored in the system as personal information, the computer searches for the input password, and if there is a corresponding password, the output means gives permission to pass the reception.

According to this method, the pass of acceptance is issued by a password stored in advance, so that all data can be directly obtained from the input password without performing the operation of finding the relevant data based on the data written on the card. A search method is available. In this case, the user does not need to carry the magnetic card, which is convenient for operation. However, the system needs to search for the password registered from the vast amount of personal information entered. In a small system, it takes too much time to make a decision, and it is difficult to put it to practical use.

In many cases, the password determined by the user uses a number similar to the person's date of birth or home telephone number. Is sometimes decrypted, and even such a large system does not always guarantee security. For this reason, there is a demand for a new system that is less likely to be illegally used by a lost card with a simple system.

[0009]

In order to achieve the above object, the present invention provides a magnetic card reading means 1 and an arithmetic means 2 for processing read data read from the magnetic card reading means 1.
And a data storage means 3 for storing the read data, a numerical data input means 4 is provided near the magnetic card reading means 1, and a magnetic body 5 read by the magnetic card reading means 1 is a copyable card. 6, the data written in the magnetic body 5 is read by the magnetic card reading means 1, and the read data or the data processed by the arithmetic means 2 is stored in the data storage means 3, and the magnetic card reading means 1 There is provided a comparing means 7 for comparing the read data to be read with the numerical data inputted by the numerical data input means 4, and the comparing means 7 compares the read data of the magnetic card reading means 1 with the input data of the numerical data input means 4. By outputting the coincidence after processing by the arithmetic means 2 to the judgment output means 8, the input person suitability judging operation for confirming the identity can be surely performed.

The arithmetic means 2 having the same function as the arithmetic means 2
A magnetic card reading / writing means 1a and a data display means 10 are provided on a frame 9 provided with a. A magnetic body 5 read by the magnetic card reading / writing means 1a is formed on a copyable card 6 such as a business card. Then, the magnetic card read / write means 1a writes and duplicates the data written on the magnetic body 5 read by the magnetic card read / write means 1a to another card 6, and the arithmetic means 2a reads / writes the magnetic card. By displaying the processing result of the read data of the magnetic body 5 read by the means 1a on the data display means 10, the system instructs numerical data to be a special password for each card.

Further, the data display means 10 is provided with a display selection means 10a, and the data display means 10 selectively displays the read data read by the magnetic card read / write means 1a and the processing result of the arithmetic means 2a. Yes, if the data of the magnetic body 5 of the card 6 is displayed, it is possible to easily confirm whether the personal data is correctly input when the card 6 is copied.

[0012]

The magnetic body 5 of the card 6 according to the present invention usually has personal information such as an address and a name written thereon. When the personal information is inserted into the magnetic card reading means 1 and passed therethrough, the personal information is received by a receiving device, It is read as personal information by the microcomputer device. Next, if the password displayed on the data display means 10 corresponding to the magnetic body 5 of the card 6 and informed to the person in advance is input to the numerical data input means 4, the input password and the magnetic card reading means 1 are read. The read data is processed by the arithmetic means 2 and the result is output from the judgment output means 8. If the two data match, it can be confirmed that the person notified of the password has input.

[0013] As described above, the personal information for identity verification is not stored in the system including the password, and the system of the input user suitability judging apparatus of the present invention needs to store a large amount of data. Because it is not available, it can be easily configured. That is, since the conventional determination of the propriety of the input user is performed by using a large computer and comparing the input password with a pre-registered password, the amount of data to be stored is large, and the time required for the search is large. Although it was practically impossible to realize this with a computer system such as a microcomputer, the present invention only requires simple arithmetic means 2 instead of storing a large amount of data. It was done.

Further, even if the magnetic card 6 is analyzed, it is impossible to decrypt the password only by the written personal information. Because of this,
A magnetic body 5 is formed on a card 6 such as a business card in which personal information is written in characters, and personal information is written in the card 6.
When the personal information read from the magnetic body 5 by the magnetic card reading / writing means 1a is copied to another unused card 6 such as a business card, the third person who received the card 6 wrote the magnetic body 5 Personal information can be used freely. In addition, one's own business card can be used as it is to obtain permission to pass through the reception.

Since the frame 9 for duplicating the card 6 is provided with the arithmetic means 2a and the data display means 10, the data display means 10 processes the read data read from the card 6 by the arithmetic means 2a and processes the result. The numerical data is displayed as a password, and the owner of the card 6 can know the password suitable for the system. This frame 9
The data display means 10 is normally in a mode for displaying personal information written on the card 6, and when the special display selection means 10a is operated, the calculation result by the calculation means 2a is displayed. From this, it is possible to confirm the personal information to be written on the magnetic body 5 when the card 6 is copied,
There is no danger of writing erroneous data to the duplicate card 6, and the duplicate of the card 6 is surely performed.

[0016]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the embodiment shown in the drawings. 1 is a magnetic card reading means attached to a microcomputer device or the like, 4 is a numerical data input means installed near the magnetic card reading means 1, and 6 is a magnetic card reading means. A card having a magnetic body 5 which can be read by the card reading means 1 and a judgment output means 8 for outputting a status of the propriety of an input person. Is used as a device for determining the suitability of an input person in a system for accessing data and changing information.

The method of use of the present invention is not limited to the ordinary device for judging the suitability of an input person, but the input person passes the portion of the magnetic body 5 of the card 6 through the slit of the magnetic card reading means 1 and sends the password to the numerical data input means 4. By inputting numerical data exclusive to the input person, the personal identification is performed and the matching output means 8 outputs the coincidence. Therefore, the judgment output means 8
When it detects a match in the output, it unlocks the door at an unattended reception, or if it is a microcomputer device for data input,
You can proceed to the next input step.

The details of the conventional system are as follows. An input person name read from the magnetic body 5 of the card 6 is searched for in a person registered in advance as an input person of the present system. A determination is made as to whether the password input from corresponds to the password of the registered person, and the result is output to the determination output means 8.

Therefore, this system needs to analyze a large amount of data using a large computer, and it is difficult to implement a very small computer system called a microcomputer because the amount of data that can be handled is limited.
Since the determination is a simple one utilizing a part of the series of operations, the accuracy is inferior and unauthorized use cannot be completely prevented.

The present invention relates to a device which can judge the suitability of an input person with a precision comparable to that of a conventional large computer even when using a microcomputer device.
A data storage means for temporarily storing read data read from the magnetic card reading means 1; and a data storage means 3 for temporarily storing read data read from the magnetic card reading means 1. Data or data processed by the arithmetic means 2 is stored.

Numeral 7 is comparison means for comparing and examining the data input by the numerical data input means 4 and the read data read from the magnetic card reading means 1. The comparison according to the present invention compares the perfect coincidence of both data. The greatest feature is that a comparison is made as to whether or not the result of processing one of the two data by the arithmetic means 2 is the same.

That is, in order to determine whether or not the input person according to the present invention is appropriate, the microcomputer device includes an arithmetic unit 2, a data storage unit 3 for temporarily storing data, and a data comparison unit 7.
And only the judgment output means 8 for outputting the comparison result, there is no need for storage means for a huge amount of personal information including a password conventionally required for this kind of equipment. And
The suitability judging device specifies numerical data to be a password to the input person from the personal information written on the magnetic body 5 by the input person.

This numerical data, which is informed to the input user in a secret state, is unknown to anyone except the user, and has no commonality with friends who use this input user suitability determination system. It is impossible to analyze more than the conventional password. Moreover, the personal information written in the magnetic body 5 as the base is common, and even if a third party picks up the card and analyzes it, he or she does not know anything other than the written personal information, and It is impossible to analyze the password from this data.

The content of the arithmetic means 2 for implementing the present invention is a black box, and if an example of a mechanism for arithmetically processing read data read from the magnetic body 5 is shown,
A predetermined number of character codes are extracted for every Y characters from the Xth of the read data, and the character string of this character code is rotated, inverted, added to or subtracted from the numerical value Z, and converted into a meaningless numerical string. The numerical value sequence represented as numerical data is designated to the input user as a password.

As a result, the arithmetic means 2 designates not only the arithmetic mechanism but also numerical data which is a completely different password by simply changing a variable during the arithmetic operation. Even if there is a password, the input user does not know what password has been specified at all, and only the input user knows whether or not the password can be properly determined.

As described above, the data written in the magnetic body 5 does not need to be kept secret.
Does not need to be limited to one card. For this reason, there is no problem even if the data distributed in large quantities and written on the magnetic body 5 is analyzed. Therefore, in the present invention, the magnetic body 5 is formed on a card 6 such as a business card which always has the By duplicating and writing predetermined data on the body 5, a card 6 such as a business card at hand can always be used for judging the suitability of the input person.

Further, in the case of a business card, the character information written on the surface can be written as it is as personal information on the magnetic body 5, and the person who receives the business card can copy the data written on the magnetic body 5 The card 6 can be read and used as information that can be understood by a computer, and the card 6 is used not only for judging the suitability of the input person but also for other uses.

On the other hand, the password of the present invention is given exclusively to the system to be used. That is, reference numeral 2a denotes an operation unit having the same function capable of performing the same operation processing as the operation unit 2, 1
a is a magnetic card read / write unit having not only a read function but also a write function; 3a is a data storage unit for temporarily storing data read by the magnetic card read / write unit 1a; 10 is a magnetic card read / write Data display means for displaying the read data read by the means 1a;
Each of these means is provided on the frame 9.

Reference numeral 1b designates a read / write mode setting means for changing the read / write mode of the magnetic card read / write means 1a.
Is a display selection means provided alongside the data display means 10,
The normal data display means 10 displays the read data read by the magnetic card read / write means 1a by the display selection means 10a, and when the read / write mode setting means 1b sets the write mode, the magnetic card read / write By passing the new card 6 through the loading means 1a, the read data stored in the data storage means 3a and displayed on the data display means 10 is written on the magnetic body 5, so that the copy of the card 6 can be easily made. .

At this time, if the display mode of the data display means 10 is set to the operation result of the operation means 2a by operating the data display selection means 10a, based on the read data read by the magnetic card reading / writing means 1a, The arithmetic means 2a performs arithmetic processing and displays the resulting numerical data. Since the operation of the arithmetic means 2a performs the same arithmetic processing as the arithmetic means 2 of the input person suitability judging device, the displayed numerical data matches the password of the input person, and this numerical data is transmitted to the numerical data input means 4. By inputting, it becomes possible to access the reception permission and the microcomputer device.

Reference numeral 11 denotes a personal computer, and 12 denotes an R for connecting the frame 9 and the personal computer 11.
An interface means including an S-232C connection code. When a dedicated data creation function is not to be waited in the frame 9, data to be written to the magnetic body 5 is created by the personal computer 11, and the data is stored through the interface means 12. This data is written to 3a.

The data written in the data storage means 3a can be written in the magnetic body 5 of the new card 6 by setting the read / write mode setting means 1b to the write mode. When the card 6 is completed, a plurality of copies can be made using the magnetic card reading / writing means 1a provided in the frame 9 even if the interface means 12 is removed.

[0033]

According to the present invention, in order to give permission to pass the reception and to enable access to the microcomputer device, it is necessary to confirm the identity of the user. Then, the user inputs the password to determine whether the password is correct. However, this system performs an operation of searching for a password from a large amount of personal information and determining whether or not it is appropriate. With a small-sized system, there are problems in the data amount and search time, and practical operation is difficult.

According to the present invention, the personal information to be used is written in the magnetic body 5 of the card 6 without storing the personal information in the system, the data is read by the magnetic card reading means 1 each time, and the password is read. Calculation means 2
This is specified in the numerical data obtained as a result of the arithmetic processing.

For this reason, the input user simply passes the card 6 through the magnetic card reading means 1 and inputs numerical data which is a password with the numerical data input means 4, and the judgment output means 8 outputs the read data and the arithmetic means 2 Outputs the coincidence with the input password processed by the system, and therefore, the system substantially only includes the calculating means 2 and the judgment output means 8, so that the system can be configured very simply.

Further, the numerical data of the calculation result corresponding to the password is determined by the calculation means 2 and becomes numerical data completely unrelated to the user's home telephone number or the date of birth, so that a third party analyzes this numerical value. It is almost impossible and very secure.

The computing means 2 is substantially a black box. If the numerical value referred to by the arithmetic means 2 changes, the system indicates completely different numerical data as a password. Therefore, even if the card 6 in which the same personal information is written is used, a different password is used if the system used is different. It is what is instructed. It is important for this system that data is written on the magnetic body 5, and there is no reason why the contents of the written data must be kept secret. For this reason, it is not necessary to carry one card 6 with care, and a very rough use of replenishing a plurality of cards 6 and replenishing them when the card 6 is lost can be achieved.

As described above, since the card 6 can be copied and used, as the card 6 forming the magnetic body 5, the magnetic body 5 is formed on a business card distributed in large numbers, and the characters written on the business card with characters are written. If the information is written on the magnetic body 5, the personal information written on the magnetic body 5 of the business card by a third party who has received the business card can be freely used as computer-readable information. The user of this system can use the business card as it is to judge the suitability of the input person, and the card 6 can be used for multiple purposes.

In addition, the input user suitability judging device needs to inform the user of numerical data corresponding to the password from the card 6 to be used. In the present invention, the frame provided with the calculating means 2a having the same function as the calculating means 2 The data written in the magnetic body 5 of the card 6 is read by the card reading / writing means 1a, and when the display selecting means 10a is specially operated, the calculation processing result of the calculating means 2a is stored in the frame 9. It is displayed on the data display means 10. For this reason, the user can easily know the password suitable for the system to be used.

The operation means 2a and the data display means 10
Card reading / writing means 1a provided on a frame 9 provided with
Can not only read data written on the magnetic body 5 of the card 6 but also change the mode to the write mode, so that the read data read using one written card 6 can be replaced with other unused data. By writing to Card 6, many cards could be easily duplicated.

At this time, the display selection means 10a of the data display means 10 normally displays the read data as it is, so that the data to be written to the magnetic body 5 when the card 6 is copied can be confirmed. There is no danger of writing wrong data on the duplicate card 6, and the duplicate of the card 6 can be surely performed.
