The present invention relates to a password automatic change system capable of fundamentally preventing phenomena such as theft and privacy infringement due to a leaked password, and a method for automatically changing a password of a password authentication device using the same.

Generally, schools, companies, gyms, golf courses, etc. are provided with personal lockers for students, staff, and members for the storage of valuables and other items, such lockers are usually equipped with a locking device to the user or the user's permission It cannot be opened other than the person who received it.

And the traditional lock of such a locker is mounted to each of the lock body and the door of the locker, the hook of the cylindrical lock to the lock of the locker body and the door lock form.

Therefore, the user of the locker suffers from the inconvenience of having to carry the lock key all the time, and in case of accidentally carrying or losing the key, there is a case of difficulty in using the locker.

For the reason described above, a locker that is opened and closed by inputting a password has been provided. However, in the case of the locker of the password locker type, it is inconvenient due to carrying a key of a conventional key locker and a difficulty in not using the locker until a duplicate key is matched when a key is lost. On the other hand, they always included the risk of theft and privacy breaches due to password exposure.

Hereinafter, with reference to the accompanying drawings will be described in detail the automatic password change system according to an embodiment of the present invention and the automatic password change method of the password authentication device using the same.

As shown, the automatic password change system 100 according to an embodiment of the present invention is configured to include a control unit 110, the input unit 120, the operation unit 130.

The controller 110 includes a password generation program. Accordingly, the controller 110 generates a one-time password by executing the password generation program when a variable is input through the input unit 120. At this time, the password generation program executed in the control unit 110 forms a plurality of one-time passwords, and the one-time passwords formed as a plurality are applied sequentially when used for authentication for the operation of the operation unit 130. That is, the controller 110 compares the password inputted when the password for the operation of the operation unit 130 with the current one-time password among the one-time passwords and authenticates the validity of the corresponding password by determining whether the password is the same. do.

In addition, the variable input to the controller 110 may include a fixed variable divided by the operation unit 130 and a variable variable variable by the user, the fixed variable may be two or more, and the variable variable is the input unit 120. It may be a variable input by the user through.

In addition, the password generation program of the controller 110 divides the number obtained by adding the number of units of the fixed variable and the number of units of the variable variable into a specific number, and arranges the remaining number as the last number of the fixed variable and at the same time the first number of the fixed variable. Number generates the first one-time password by dropping operation. Using the generated one-time password as a fixed variable, the number of units of the one-time password and the number of variables of the variable variable are added in turn to divide the number into a specific number and place the remaining number as the last number of the one-time password. The number may be to sequentially generate a plurality of one-time passwords by repeating the operation method to drop.

Here, when there are two or more fixed variables, a fixed variable used directly as a one-time password is previously determined through dropping of the first number of the two or more fixed variables and placing the last number of the remaining numbers.

An example in which the control unit 110 generates a plurality of one-time passwords for sequential use through the password generation program will be described with reference to FIG. 2.

As shown, the second fixed variable corresponding to the unique number of the management unit operating the storage unit operating unit 130 is 2539, the first fixed variable corresponding to the unique number of the storage unit operating unit 130 is a storage box. Poor 2572, 4582, 3783, 2470.

First, since the variable 1 input by the user is 72 in the case of the storage box 1, the password generation program of the controller 110 adds the second fixed variable, the first fixed variable, and the number of units of the variable variable in sequence, and divides them by 9 Perform the operation. In other words, we calculate (2 + 5 + 3 + 9 + 2 + 5 + 7 + 2 + 7 + 2) ÷ 9 to find the remaining 8, and then place the remaining 8 as the last fixed number of 2572 as the first fixed variable. 1 Drop 2, the first number of fixed variables, to create 5728 as the first one-time password.

The same operation is performed again using the one-time password generated through the above operation as the first fixed variable. That is, the number of units of the second fixed variable 2539, the first fixed variable 5728, and the variable variable 72 are added in sequence, and then divided by 9. Accordingly, (2 + 5 + 3 + 9 + 5 + 7). Find the remainder 5 by the operation of + 2 + 8 + 7 + 2) ÷ 9, and then place the remainder 5 as the last number of the first fixed variable 5728 while dropping the first number 5 of the first fixed variable to 7272. Generate a second one-time password.

This series of steps creates a number of one-time passwords for Locker1.

At this time, the user of the storage box 1 after reading the one-time password generation rules of the password generation program may be to calculate and enter the one-time password for each use of the storage box 1, in another form to carry a table with one-time passwords sequentially written It may be to check and input every time 1 is used.

The second fixed variable is 2539, the first fixed variable is 4582, and the variable variable is 34, so that the one-time password is 5820, 8205, 2055 in the same manner as the operation rule for generating the one-time password of the above storage box 1. , In order of 0552.

In addition, since locker 3 has a second fixed variable of 2539, a first fixed variable of 3783, and a variable variable of 11, the one-time password is 7836, 8360, 3602 through the same method as the operation rule for generating the one-time password of the above locker 1. , In order of 6025.

In addition, since locker 4 has a second fixed variable of 2539, a first fixed variable of 2470, and a variable variable of 36, the one-time password is 4705, 7058, 0583 in the same manner as the operation rule for generating the one-time password of the above locker 1. , In order of 5838.
