JPH03174651A - Confirming system for erroneous input of password - Google Patents

Abstract

PURPOSE:To enable a user to decide the cause of an erroneous input in order to evade the second wrong input by displaying only the input wrong password. CONSTITUTION:A password is checked when the input of the password data is through up to four digits after the guidance is displayed for input of the identification number. When the coincidence is confirmed between both identification numbers, these coincident numbers are not displayed and the next processing is carried out. When no coincidence is obtained between both identification numbers, the noncoincidence conditions are checked. Then the noncoincidence, if larger than N times, is treated as the abnormality. When no coincidence is obtained between both numbers and the abnormality is not treated, the input guidance display is carried out again and at the same time the identification number inputted wrong is displayed. A customer is aware of the mere mispush of the identification number by reference to the reinput guidance and then inputs a correct identification number. Thus it is possible to decide the cause of the wrong input and to decrease the card invalidating/ collecting frequency.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for displaying an incorrectly input password in a password input method for an automatic teller machine or the like.

[Conventional technology]

In the conventional PIN input method, for example,
As described in Publication No. 7169, an asterisk (*) etc. is displayed for each digit of the PIN code, allowing the customer to know how many digits have been entered and preventing incorrect input.

[Problem to be solved by the invention]

The above-mentioned conventional technology does not take into account incorrect input of the password due to misalignment of the touch input position when using a touch panel, for example, and there is a problem in that the customer continues to re-enter the password without knowing what he or she did wrong.

The purpose of the present invention is to allow customers to determine the cause of erroneous input and to prevent them from inputting erroneous information again.

[Means to solve the problem]

In order to achieve the above object, the incorrectly inputted password is displayed only when the wrong password is input.

[Effect]

According to the present invention, only the incorrectly input password is displayed when the password is input, and the correct password is not displayed, so that the confidentiality of the password can be maintained as before.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1-4.

FIG. 2 is a schematic diagram of an automatic teller machine showing an embodiment of the present invention. The main part is the control unit that performs arithmetic processing, responds to various signals, and controls the entire device. 2 is a main storage device that temporarily stores various data and stores control programs. 3 is the Banknote Management Department (BRM) that handles banknotes. 4 is a passbook printing mechanism unit (PBM) that prints out and takes out the passbook. 5 is a card/statement slip mechanism unit (SHU) that reads cards and prints and issues statement slips. 6 is a coin deposit and withdrawal mechanism department (COM) that handles coins. 7 is a display unit (CRT) that guides the customer's operations and provides guidance.

FIG. 1 shows the main points of this embodiment, and the processing to be performed when the customer unconsciously inputs the wrong password when inputting the password will be explained below.

The process starts from the start in FIG. After displaying the guidance 8 for entering the PIN (see Figure 3), when the PIN data input 9 has completed up to 4 digits, the process moves to 10 to check the PIN, and after confirming the PIN 12, it matches. If so, the matching PIN is not displayed and the process moves on to the next process (the process after entering the PIN is the same as in conventional automatic teller machines). If they do not match, check the mismatch conditions 13
do.

For example, the number of mismatches is checked, and if it is greater than N times, it is treated as abnormal.

If the PIN does not match and the error processing does not proceed, the re-input cadence will be displayed (see Figure 4)14, and the incorrectly entered PIN will be displayed accordingly.15゜This is an incorrect PIN. Therefore, there is no need to worry about confidential information being leaked. When the customer sees this re-entry guidance, he or she realizes that the PIN number was simply pressed incorrectly, enters the correct PIN number, and moves on to the next process.

〔Effect of the invention〕

According to the present invention, since it is possible to visually confirm a PIN number that has been entered incorrectly, it is possible to determine whether the cause of the erroneous input is simply a mistaken press of a button or touch panel, or a mistake in remembering the PIN number itself. This also has the effect of reducing the number of processes such as invalidating and collecting cards by determining the cause of incorrect input.

Claims (1)

[Claims] 1. An automated teller machine that compares PIN numbers compares the PIN entered by the customer at the time of transaction with the PIN registered in advance, and only if there is a discrepancy, the PIN entered by the customer is replaced. A method for confirming incorrect input of a PIN code.
