Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a system for performing personal identification (verification) using a personal identification number in financial transactions such as cash withdrawals.

BACKGROUND OF THE INVENTION Cards are now widely used in personal identification systems, and these cards include a card that identifies the bearer of the card as the legitimate cardholder when the card is used. The PIN number is memorized. When personal identification is performed using this card, for example, in a bank deposit withdrawal machine, the withdrawal machine reads the PIN number of the inserted card, then requests the cardholder to input the PIN key, and then uses the key input. The personal identification number read from the card is compared with the personal identification number read from the card to determine that the card holder is a legitimate card holder, and subsequent transactions are then carried out. In this system, the PIN number uses a combination of relatively simple numbers (for example, a sequence of four digit integers) so that the cardholder can memorize it.

The conventional method of inputting a password will be explained below.

FIG. 6 shows a conventional password input device. In FIG. 6, 1 is an input key, which includes a group of 10 numeric keys 1a from numeric @Oa to @9'', and a recognition key 1b.
and a cancellation key 1c. The card bearer inputs the stored four-digit personal identification number from the numeric key group 1a sequentially from the higher digits. When all digits have been entered, the recognition key 1b is pressed. If you make a mistake during the process, press the cancel key 1C and try again from the upper digits. Withdrawal machines often have a set number of times that you can cancel your transaction, and if you exceed this limit, you will not be able to make any further transactions.

Problems to be Solved by the Invention However, in the conventional PIN input method described above, when the card holder is manually entering the PIN, a third party may enter the PIN from the vicinity by using the finger movement of the card holder. If a malicious third party were to be able to decipher the PIN number and obtain this card for some reason, such as theft or loss, the card could be used to conduct financial transactions freely, which could lead to a crime. .

The present invention solves the above-mentioned problems, and aims to provide a personal identification system that makes it impossible for a third party to decipher the personal identification number from the input operation of the personal identification number of the card holder.

Means for Solving the Problems In order to achieve this object, the personal identification system of the present invention uses a password display pattern each consisting of numbers, symbols, nine characters, etc., and a password display pattern specified by an authorized card holder. a card storing a pattern code and a pin code selected by an authorized card holder from the pin code display pattern, a card reading means for reading the pattern code and a pin code stored in the card, and the card reading means. a read data storage means for storing a pattern code and a PIN code read from the read data storage means; and a PIN code display pattern that is intended to be a dummy or has no display or includes two characters of symbols according to the pattern code stored in the read data storage means. a display means whose arrangement is changed each time it is inserted so that the selected display can be determined; an input selection means which selects an input by turning a diamond μ in the display including a dummy of said display means; and said password selection means. The card holder has a configuration of a PIN code input means including a writing means that allows a card holder to select a display pattern and write the pattern code on the card.

Function: This configuration allows the cardholder to select a PIN display pattern that is easy for the card holder to remember, and also changes the arrangement of the selected PIN display pattern each time the card is inserted, reducing the manual effort required to turn the dial. You can mix and choose and enter your pin code.

The operation of the two-person identification system configured as described above when using a card will be described below with reference to FIG. 6.

In Figure 6, the card holder first enters the PIN code,
The card 2 on which the pattern code for displaying the password, the password, and the value information are written is inserted into the card reading means 3 (stopl). Then, the card reading means 3 reads the pattern code of the password display pattern stored on the card 2, and stores the pattern code in the read data storage means 4 (stop 2). Next, the card reading means 3 reads the password code stored in the card 2, and stores the password in the read data storage means 4 (stop 3). Next, read the pattern code from the data storage means 4 and display it on the display means 6a of the PIN code input means 6.
, and according to the pattern code, a blank pattern or a pattern containing 9 symbols intended as a dummy, such as numbers, alphabets, katakana, etc., is mixed with dummies, rearranged, and displayed on the display section 3o of the display means 5a (stop 4).
. Changing the arrangement here means changing the position of the beginning of the pattern, but the arrangement remains the same. Next, the cardholder is prompted to enter the PIN code. The cardholder selects the input by turning the pattern displayed on the PIN code display section 30 (Diamond) v 33 (top 5), and inputs the 1 digit of the PIN code by pressing the confirmation key 34 (5top 5).
stop 6). If the entered PIN code is a dummy when the dummy button 32 is pressed, it is determined that no input has been made and prompts the user to enter the PIN code again.
If the entered PIN code does not mean dummy 32 (gtep7L), it will then determine whether all digits of the PIN code have been entered, and if all digits have not been entered, prompt for the PIN code again, and if all digits have been entered. If so (stop 8), the entered PIN code is stored in the input data storage means 6 (s
top 9), the verification means 7 verifies the PIN code stored in the read data storage means 4 and the PIN code stored in the input data storage means 6 (stoplo);
If it is determined to be legitimate, subsequent financial transactions are performed (stopl 1 ). If the card is judged to be unsuitable, no further financial transactions will be made and the card will be returned.
