Abstract

[PROBLEMS] To provide a security system capable of prohibiting a general unauthorized input by an unauthorized person, allowing a slight input mistake by an authorized person, and suppressing an unauthorized action in advance, thereby improving security. [MEANS FOR SOLVING THE PROBLEMS] Numbers which may be inputted by an unauthorized person (such as the birthday or the telephone number of the authorized person) are set as boobie numbers. When an unauthorized person inputs one of the numbers, the system judges that an abnormal action is caused and instructs an abnormality countermeasure such as an alarming or locking. On the other hand, when the authorized person makes a slight mistake such as inputting an incorrect character while inputting his/her password, the system does not instruct an abnormality countermeasure. Thus, it is possible to prohibit a general unauthorized input by an unauthorized person and allow a slight input mistake by the authorized person.

Description

Specification

Security System Technical Field

[0001] The present invention relates to a security system for maintaining security with a personal identification number in an ATM machine, security door, the Internet, a window of a financial institution, and the like.

Background art

In recent years, security systems based on personal identification numbers have been used in various fields such as ATM machines, security doors, the Internet, and counters of financial institutions.

[0003] For example, in the case of a bank ATM machine (Auto Teller Machine), when a cash card is issued to a customer, a personal identification number specified by the customer is transmitted to the system in accordance with the cash force code. Remember. Then, when the customer inserts the cash card into the ATM machine and enters the PIN, the ATM machine communicates with the center to check the entered number against the PIN stored in the system, and If they match, withdrawal and transfer of cash are allowed. Further, even if a customer makes a mistake in inputting a password, the user can input the password up to a plurality of times (usually about three times) (for example, see Patent Document 1).

[0004] However, in the conventional security system, there is a problem that there is a high possibility that an unauthorized person such as a thief can illegally withdraw a deposit from the ATM machine. That is, in the conventional security system, even if the password is incorrectly input as described above, it can be input up to a plurality of times (usually about three times). (Enter the birth date, phone number, etc. of the true owner of the smart card as a personal identification number) multiple times, which increases the possibility of unauthorized withdrawal of the deposit.

[0005] Of course, it is conceivable that a mistake in entering the password at least once locks the door, turns off the alarm, or allows security guards to rush, but this does not mean that the true owner ( There was a problem that even a trivial input error of the genuine person was not allowed and it was inconvenient.

[0006] Such problems are not limited to ATM machines, security doors, the Internet, and financial services. Occurs in anything where a security system based on a personal identification number is used, such as institution windows.
