Abstract

PURPOSE:To prevent illegal usage and to improve security even if a registration card is lost by interactively storing and registering data on personal feature under plural items in a registration card and changing the collation order at every collation. CONSTITUTION:A terminal equipment 4 interactively stores and registers personal feature data under plural items in the IC card (registration card) 1 and sets the collation items plural. A program changing the order of collation items at every collation is stored in the card 1. If a password is collated to obtain agreement in use of the card 1, personal inherent data is interactively outputted from the card 1, and displayed on the terminal equipment 4. When a user of the card 1 inputs answers to the card 1 through the terminal equipment 4, collation is made in the card 1. If the input is correct, a next question is outputted. If this action is repeated several times to obtain the right collated results, the card user is authorized. Thus the illegal usage is prevented to improve security.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a personal identification system t using a registered card such as an integrated circuit card (hereinafter referred to as an IC card), and particularly relates to a personal identification system t using a registered card such as an integrated circuit card (hereinafter referred to as an IC card). This is intended to improve the quality of life.

[Prior art] Conventionally, I have been used as a personal identification system and as a registration card.
Using a C card, the holder's personal characteristic data etc. are stored in advance using an IC card.
In some cases, personal characteristic data is registered in each card, and when identifying an individual, a discrimination means reads the personal characteristic data registered in the registered card, compares it with input data, and outputs a determination result.

[Problems to be Solved by the Invention] However, in the conventional example, only the personal identification number was the personal characteristic data to be verified.
It is easy for people other than the owner to remember the IC card, and if the IC card is lost, there is a risk that it will be stolen.

Therefore, the present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a personal identification system that can further improve security.

[Means for Solving the Problems] A personal identification system using a registration card according to the present invention allows the registration card to store and register personal characteristic data covering a plurality of items in an interim format, thereby creating a plurality of verification items. With,
The collation order is changed for each collation.

[Function] According to the personal identification system using a registered card of the present invention, there are multiple items to be checked and the order of checking changes each time, so even if the registered card is lost, there is no risk of it being misused. There is no

[Example] An embodiment of the present invention will be described below.

In the figure, (1) is an IC card, (2) is a reader/writer, (3) is a key switch, and (4) is a terminal such as a personal computer. In 1), personal characteristic data covering multiple items is memorized and registered in an interim format to create multiple verification items, and the IC card (1) also includes a program that changes the verification order for each verification. be remembered.

That is, the terminal device (4) stores the identification number, personal information 1-n, and other information in the IC card (1) as personal characteristic data in an interim format at the time of registration.

For example, personal information that is easily known to the individual, such as height, date of birth, eyesight, number of children, company extension number, and blood type, can be converted into a four-digit numerical value such as the following. is input.

■Height 1735 (meaning 173.5cm)
■Birthday 1205 (Meaning of December 5th) ■Visibility 0102 (Meaning of left 0.1, right 0.2)
■Number of children 0102 (meaning 1 boy and 2 girls) ■Company extension number 1234 (meaning of 1234 number)■
Blood type 0010 (1st look) Determine in advance as follows: A type...1000 B type...0100 0 type...001O AB type...0001 And when checking, use the above The order of the collation items ■ to ■ is determined as shown below and stored in the IC card (1).

Change each time you use C card (1). As a specific method, for example, there is a method in which the first digit of the total value obtained by adding up the year, month, day, hour, and minute of use for each digit is set as the collation order Ca5e No.

[Example] When using an IC card, December 26, 18851
Since it is 0:53, a question is issued from the IC card (1) according to Ca5e3 (if it is 0, it is set as Ca5elO).

The above calculation is performed from the year, month, date and time using a terminal (0 built-in calendar clock and calculator.Then, the resulting numbers are input from the terminal (4) to the IC card (1), and the IC card (1) Questions for verification are issued according to predetermined verification Ca5e numbers.

The collation Ca5e number and collation order may be arbitrarily determined;
If the verification Ca5e number is 9 or less and the result of the above calculation is greater than or equal to the verification Ca5e number, subtract the verification Ca5e number from the answer and use the value as the true verification C.
The number shall be a5e.

[Example] When using an IC card, December 2B, 18851
If the verification Ca5e number is 5 at 0:58, 1+9+8+5+1+2+2+8.1+0.5+ll=
9>5 9-5=4 Therefore, a question for verification is issued from the IC card according to Ca5e4.

The operating procedure based on the above points is as follows: First, register your personal identification number and personal data in the IC card (1) in an instant format, and when using the IC card (1), use the reader. Attach the IC card (1) to the writer (2) and enter the password using the key switch (3) or terminal (4). The input data is compared within the IC card (1), and if there is a mismatch, a mismatch signal is output from the IC card (1). If they match, then the IC card (1) outputs personal data in the form of a question and displays it on the key switch (3) or terminal (4). After seeing the question, the IC card user answers using the key switch (3) or the terminal (0).
[If you input it to card (1), it will be checked in IC card (1), and if the input answer is correct, it will output the next question. (If the answer is wrong, it will output that fact.) Repeat the process multiple times, and if all verification results are correct, IC
It is determined that the card user is legitimate. Even if someone else remembers the password, unauthorized use of the IC card (1) can be prevented as long as the person's unique data cannot be remembered, resulting in high security.

In the above embodiment, if the individual-specific data registered in the IC card (1) differs from the actual information (relocation, job change, family transfer, etc.), re-registration is sufficient.

Furthermore, although the above embodiment has described an example of an IC card as the registration card, a laser card may also be used.

[Effects of the Invention] As described above, according to the present invention, in a personal identification system using a registration card, personal characteristic data covering two or more items is stored and registered in the registration card in an interim format, and verification items can be set. Since there are a plurality of cards and the order of verification is changed for each verification, there is no risk of the registered card being misused even if the registered card is lost, and security can be improved.
