Abstract

PURPOSE: A password authentication system is provided to enable a user to offer a preregistered password to a criminal when the user is threatened by the criminal, and to perform an emergency measure while money is being withdrawn if the preregistered password is input. CONSTITUTION: The system comprises several steps. A user initially registers a password, including a conventional part and a preliminary part, at a password authentication system where the preliminary part is for a normal money withdrawal and some emergency measures. The password authentication system checks a basic password, then compares a preliminary part of an input number with a registered normal number, and enables the input money to be withdrawn in a case that the preliminary part is the same as the registered normal number. But in a case that the preliminary part is the same as an emergency measure call number, the system enables the input money to be withdrawn and calls a corresponding emergency measure.

Description

Password certification system for crime prevention

The present invention relates to password authentication, which is an important factor in verifying identity in financial transactions such as deposits, credit cards, loans, and other services. More specifically, the present invention restricts behavior by crimes such as kidnapping or detention. If you are forced to reveal your password in advance, you will be able to withdraw it when the criminal attempts to withdraw the money using the password you acquired, but you will be notified to the police or family automatically. It is about a password authentication system that allows for a countermeasure.

As is well known, the use of passwords is rapidly increasing in the modern credit society, and the importance of passwords related to financial transactions need not be mentioned any more.

However, the password used for such financial transactions, that is, the password of the bank account that can withdraw money or the password used for credit cards, is obvious to bring huge losses if it leaks to others.

If someone leaks a password like this, they may know others by mistake, but they may inevitably leak it by kidnapping, assault, threat, or intimidation. In this case, a criminal may withdraw money and then kill the victim. Monetary damage and loss of life will be suffered at the same time.

Or, after a criminal withdraws money and escapes the victim and releases the victim, the financial institution or the police will know that the victim has to report it, so it is too late to track the criminal after escape.

As described above, if the victim is in a state of being arrested, he cannot ask anyone for help, and if he or she is forced to seize the password, if he falsely seizes it, the criminal can immediately find the money. In order not to suffer, it will be impossible to unseat the correct password.

The present invention has been made in view of the above problems, in the configuration of the password system in addition to the basic password divided into a preliminary number indicating the situation that the money is withdrawn, and withdrawal from the preliminary number is possible crime By registering and registering a number indicating that the withdrawal is made by means of an emergency number, if the withdrawal is made by an emergency number, the family or the police will be notified of this fact, or the amount to be withdrawn can be taken. will be.

1 is a functional diagram of the password authentication system according to the present invention

Hereinafter, the configuration of the present invention in detail.

Password registration

When a user registers a password in the password authentication system of a financial institution, the password is divided into a basic password at the front and a spare number at the back.

For example, a basic password consisting of 3 to 4 digits plus 1 to 2 digits of spare number.

The spare number in the latter part designates one possible number for normal withdrawal and several other emergency numbers.

Among the preliminary numbers, the remaining numbers except for the number designated in the registration step are automatically designated as impossible to withdraw.

Authentication system configuration

In this state, an authentication system, such as an ATM or a financial institution's own authentication system, is provided with an existing authentication system in addition to a function of distinguishing whether it is a normal withdrawal or an emergency number withdrawal by inputting a password.

That is, as can be seen in Figure 1, the system of the present invention begins by inserting a card (or bank account).

Recognition stage

Make sure that the card can be used normally by its own program. If it is recognized as a card that is not normally used, it prints a guide letter and ends immediately.

Selection step

If you print a message asking you to select a usage and make a cash service or deposit withdrawal, you will be taken to the next step. Other services will be connected to a system that performs other functions of notification. It ends at the same time.

Password Entry Step

After outputting the password to enter the password, if you enter the password is connected to the next authentication procedure, if not entered for a certain period of time and outputs a guide letter and ends.

Enter all the preliminary numbers registered in the password registration step.

Password authentication step 1 (default password match)

After checking whether the default password matches the registered password, if it matches, it goes to the next step.

Password verification step 2 (make sure your spare number is a normal withdrawal number)

After comparing whether the preliminary number matches the registered normal withdrawal number, if it is determined to be normal, the letter is outputted after inputting the amount of money and the amount is terminated.

If the preliminary numbers do not match, the next three steps of password authentication are performed.

Password verification step 3 (make sure your spare number is an emergency number)

If the preliminary number coincides with the registered emergency number, the preliminary emergency action is executed and at the same time, it is determined to be a normal withdrawal, and a letter is outputted after inputting the amount, which is the next step.

If the preliminary number does not match the normal withdrawal number and the emergency number does not match with the emergency number, the password mismatch is output and the end is completed.

Withdrawal amount input step

In the password authentication step 2 and 3 above, if the preliminary number of the password matches the normal withdrawal number or the emergency number, a letter for inputting the amount to be withdrawn is output.If the desired amount is entered, the cash is paid. It ends.

However, if the preliminary number matches the emergency number in step 3 of the password authentication, normal withdrawal is made as in the above steps, but various emergency measures are carried out, which means that the preliminary number matches the emergency number. It means that abnormal withdrawal of urgent state such as leaked by forced pressure in the state of confinement is possible, and if it is impossible to withdraw, it can be harmed by the offender. something to do.

There are a number of ways to deal with this situation. For example, first of all, contact by means of communication means to automatically notify the person through the mobile phone to a close person such as a victim's family or a co-worker. To get in touch.

In this case, the person who has been contacted knows that the withdrawal of money has been made while the victim's body has been restrained, so he can take his own action such as contacting the police.

Alternatively, such automatic contact may be made directly to the police.

Another urgent action is to set a limit on the amount that can be withdrawn, if the reserve number matches the emergency number, enter the total amount of deposit or withdrawable amount in advance (eg, half of the amount that can be withdrawn, or 1 million won). By reducing the amount of monetary damage in the first place.

In addition, by informing a bank branch that a criminal attempts to withdraw the money, the CCTV can be operated to take detailed measures such as detailing the appearance of the withdrawal person. In such a case, disturbing measures such as alarms are not desirable, and secret notifications will be required so that only security personnel can know.

Looking at an example in which the system of the present invention operates in anticipation of a case where a criminal attempts to withdraw money illegally by coercion after kidnapping one victim by the system of the present invention as described above.

Two criminals kidnap and confine the victims, steal the deposit card by violence, and then spoil the password, while another criminal attempts to withdraw the deposit while one criminal monitors the victim.

At this time, the victim must provide the emergency number registered in advance when giving the preliminary number. In this case, the criminal cannot know whether the preliminary number is the emergency number or the normal number.

After one of the criminals reaches the bank and attempts to withdraw the money, they enter the password the victim taught.

At this time, the authentication system according to the present invention operates, and if the preliminary number is the emergency number in the preliminary number authentication after the basic password is authenticated, the criminal who attempts to withdraw the preliminary number is the emergency number. You will withdraw the deposit without knowing the recognition.

As soon as the preliminary number input by the system of the present invention is recognized as an emergency number, the system for executing another emergency action is activated.

First, the amount that can be withdrawn is displayed as a predetermined amount, so only the amount within the range can be withdrawn by the criminal. Therefore, damage to the amount can be minimized.

Another family member or company colleague is automatically notified of such facts, so the police are immediately asked to investigate and the criminals can be traced as soon as possible, even if the police are notified directly.

As a further measure, security officers in branches of financial institutions are notified of such facts, and CCTVs are intensively photographed at the ATMs and counters. Actions can be taken, such as following a criminal.

As a result, it is possible to proceed quickly as soon as possible to rescue the victims and arrest the criminals.

In the process of designating and authenticating the preliminary number of the present invention as described above, the process of subdividing the number may be precisely performed, for example, if it is bound to be monitored by another criminal or is incarcerated alone. If the state, the approximate location of imprisonment, etc. are pre-determined and entered into the authentication system, and the criminals are notified correctly, the financial institution, the police, or the family will be able to respond more quickly and accurately.

As described above, according to the present invention, when a preliminary number is added to an existing basic password and registered in the authentication system, and the password must be leaked by force majeure, the appropriate password promised in advance is leaked according to the situation. It is a very useful invention that makes it possible to prevent crimes as well as the resolution of crimes and those who plan crimes are burdened with committing such crimes.

Claims (2)

After inputting a card or bankbook, it recognizes whether it can be used normally.Then, it prints a message asking you to select a use.If you select cash service or deposit withdrawal, it prints a letter asking for a password.
