[Embodiment] Next, an embodiment of the present invention will be described in detail with reference to the drawings.

(1) Description of Configuration FIG. 1 is a block diagram showing a configuration example of a password input device according to a first embodiment of the present invention, and FIGS. 2 and 3 are configuration examples of a password input unit of the password input device. FIG. 1 and 2, the password input device according to the embodiment of the present invention includes an input guide control unit 1, a password input unit 2, an input data processing unit 3, and an input digit number determination unit 4 using random numbers. . Further, the password input unit 2 includes a guide display unit 21 and an input key unit 22.

The input guide control unit 1 controls the guide display unit 21 of the password input unit 2 to display the input start digit based on the input start digit information output from the input digit number determination unit 4 based on random numbers. . The guide display unit 21 of the personal identification number input unit 2 displays an input guide that prompts the input user to input a number for designating an input start digit based on the control of the input guide control unit 1. The input key unit 22 of the personal identification number input unit 2 is used for inputting a personal identification number. The input data processing unit 3 performs processing such as collating whether the password input from the password input unit 2 is valid. The input digit number determination unit 4 based on the random number randomly determines the input start position of the password based on the random number, and outputs the determined input start digit information to the input guide control unit 1. 2 and 3
"Blanking (blank)" in the guide display unit 21 of the password input unit 2 is used as a spacer.

The personal identification number input device according to the embodiment of the present invention comprises:
When inputting a PIN into a POS register or the like of a banking machine such as an automatic teller machine at a financial institution or a supermarket, it is possible to avoid a problem that the PIN pressed by a person's arm or finger movement can be inferred. Usually, a four-digit password is used as the number, but by designating the input start position of the password at random, it is configured such that the password cannot be inferred unless the input screen is visible.

(2) Description of Operation Next, the operation of the first embodiment of the present invention will be described with reference to FIGS.
This will be described in detail with reference to FIG.

For example, in the case of pressing a password when using a POS register or the like of an automatic depositing and dispensing machine of a financial institution or a store such as a supermarket, the password is usually input in order from the first digit. When observing the place where the user is input from near the input person, 4
A digit-sized PIN is easy to find.

Therefore, in the password input device of the embodiment of the present invention having the above configuration, as described above, the password
When inputting the PIN of a digit, the input digit number determination unit 4 using a random number randomly specifies the input start position and inputs the PIN from the designated input digit, thereby avoiding inference of the PIN from anyone other than the input user. .

To explain this in a concrete example, when an input user inputs a personal identification number by pressing the numeric keypad of the input key unit 22 of the personal identification number input unit 2, the input digit number determining unit 4 based on the random number determines the input starting digit from the random number. The number is determined between 1 and 4, and the input guide control unit 1 is notified of the determined number of digits. In the example of FIG. 2, the third digit is specified as the input start position, which is the input start digit, and the asterisk mark * is blinked (strapped) to specify that the input digit is the input digit. As shown in FIG. 3, the input person inputs a four-digit password in the order of the third digit, the fourth digit, the first digit, and the second digit. Unlike the order of entering the actual PIN,
Even if the user observes the input operation from behind, the password cannot be deduced unless the input start position guided by the input start digit guide is known.

In the above-described embodiment, an example is shown in which only the first input start position of the personal identification number is randomly generated, and the personal identification number is input in order from the next digit according to the permutation.
For example, in the case of a six-digit password, if the input start position specified at random is the third digit, the third digit → the fourth digit → the fifth digit → the sixth digit → the first digit → the second digit Enter the personal identification number stored in the order of the eyes. In this case, since the digit is different from the digit stored in advance, it is necessary to trace the memory a little to remember the password of the digit at the input start position, but the next digit can be entered at the same input speed as before, and When gender is important, it is persuasive and convincing.

In this case, an input start position, which is the first digit for inputting the personal identification number, is randomly generated and specified by input means such as blinking. Blink the mark * and display the input result as unknown to a third party. Next, of the remaining three digits of the four digits, the input position of the corresponding digit of the next password is randomly designated by the random digit generation means from the random digit generation means, and the asterisk mark * is blinked. To display and suggest input. Thus, the password of the second random digit is input, and the input position of the third digit is specified at random. Also in this case, the input position of the corresponding digit of the next personal identification number is randomly designated by the random digit generation means in the input digit determination unit based on the random number, and the asterisk mark * is displayed by blinking to prompt the input.

In this way, when the password of the last digit is inputted or when each digit is inputted, the inputted password of each digit is stored in the corresponding position of the previously registered password. If the values match, the process proceeds to the next processing step. On the other hand, if they do not match, "unmatched" is displayed to prompt for re-entry. In this case as well, an input digit at the input start position is generated again by a random number, and entry is prompted from a random digit position. If the input error of the personal identification number is repeated a plurality of times, for example, three times, and if there is a mismatch, it is displayed as suspicious, the inputting of the personal identification number is stopped, and the processing is stopped.

According to the embodiment of the present invention, when inputting a password, it is possible to prevent another person from easily guessing the password pressed by the input person from behind the input person. It is possible to prevent a problem that a password is inferred from others.

[Other Embodiments] In the above-described embodiment of the present invention, an example in which an input start digit is specified has been described. However, in order to further enhance confidentiality, a password of about four digits is used as described above. A method of inputting data in random digits is also conceivable.
In this method, there are few problems when the number of digits of the personal identification number is as small as about five digits or less, but there is an aspect that the inputting of the personal identification number is troublesome, but confidentiality can be further improved.

Further, in the above-described embodiment of the present invention, the case where the personal identification number is input by a number has been described as an example. However, the personal identification number is not limited to the numeral, and may be a combination of the numeral and a symbol such as an alphabet. . Further, the number of digits of the personal identification number is not limited to four, and is not limited. Further, although an example has been shown in which the number of digits for prompting input is displayed with an asterisk mark *, this point may be a # mark or another mark.

Further, in the above-described embodiment of the present invention, the password input device alone has been described. However, the password input device of the embodiment of the present invention is, as described above, an automatic deposit / withdrawal installed in a financial institution. It can be mounted on various cash handling machines such as machines and various cash handling machines such as POS registers installed in stores such as supermarkets.

[0028]

As described above, according to the present invention,
When inputting the PIN, the input start position of the first digit to be entered is determined randomly based on the random number, and the determined input start position is controlled to be displayed on the PIN input means. In addition, it is possible to prevent another person from easily guessing the password number pressed by the input person from behind the input person, and it is possible to prevent a problem that the password number is guessed by another person as in the related art.

Further, according to the present invention, the password input of the present invention can be realized only by providing an input guide function for performing an input guide without requiring special hardware for changing a key stamp or an input key arrangement of a touch panel. be able to.
