Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may obscure the subject matter of the present invention.

FIG. 2 is a system configuration diagram of a digital device to which a method for setting and releasing a lock of a digital device is applied. FIG. Fig.

As shown in FIG. 1, the present invention is applied to a digital device 1 requiring security such as a door lock installed on a front door to prevent intrusion of a smart phone or an outsider concerned about leakage of personal information. The present invention relates to a method and apparatus for locking and unlocking a digital device, which is extremely excellent in security so that a password can not be recognized even if an unlocking process is exposed, by avoiding a locking scheme that can be easily recognized by others when exposed as a pattern.

First, a system of a digital device to which a locking and unlocking method of the digital device 1 provided in the present invention is applied includes a power source unit, a memory, a display unit 2 including a number display unit 2 and a keypad 3 exposed to the outside, (4) and a control unit for controlling them, and when a physical lock such as a door lock is provided, it may further include a driving unit connected to the power source unit to drive the lock.

The power supply unit is provided inside the body, such as a battery or a battery, to supply power to the digital device.

The 8-digit number randomly generated for the user to be recognized by the user is exposed and displayed on the number display unit 2. The user sets a lock through the keypad 3 formed on the lower side of the number display unit 2 And will be terminated. In order to facilitate understanding of the present invention, numerals appearing on the number display unit 2 are based on 8 digits for convenience of explanation, and the unlocking password to be set is described based on 4 digits.

The keypad 3 is arranged in order to be used in most telephones including the most common and familiar forms * and # so that the user can easily access them as shown in FIGS. It can be implemented in touch screen form as well as form.

The memory receives and stores an initialization password and an unlocking password set by a user to be described later, and the control unit generates an eight-digit number randomly generated in the number display unit 2 of the input screen, and the number input from the keypad is stored in the memory It compares the stored authentication number with the stored authentication number, releases the lock, and sends commands to each part to control the operation.

FIG. 4 is a flowchart showing a procedure for setting an initialization password. First, an initialization password is set before setting an unlocking password.

The initialization password may be a case where the user forgets the operation password set in the digital device 1 and is required when the user changes the calculation formula of the password or changes the initialization password, .

In case of forgetting the login ID or the password of the individual site when surfing the web by connecting to the internet through the computer, the ID and the password can be confirmed through the mobile phone authentication process. However, in the digital device to which the present invention is applied, If you do not know the password and can not use it, it is necessary to set the initialization password as above.

The setting is done by pressing the * button on the keypad (3), pressing the desired password in sequence, and pressing the # button repeatedly two times in succession.

For example, as shown in FIG. 4

(1) Unlock
(2) Unlock / Reset Password
(3) Unlock / Reset Password Reset
(4) Unlock / No password

If you want to set the initialization password to 53005268, enter '* 53005268 #' in order by pressing the keypad and type '* 53005268 #' again, and the message 'Initialization password set' is displayed. .

The designation for the four options is made by pressing the corresponding number of the keypad 3, and each option will be described in detail below.

The first unlock option does not change the settings of the initialization password and password formula but only unlocks the digital device. In case of door lock, door lock is opened, and in case of smart phone, lock screen is released.

The second unlock / password reset option enters a state where the unlock password is set at the same time as the lock is released.

The third unlock / reset password reset option is used to change the initialization password when the lock is released. If the second and third options are selected and there is no input value for setting the password for a predetermined period of time, it is preferable to inform the user by generating a separate buffer sound or blinking the number display unit 2.

The fourth unlock / no password option is for those who do not need to set a password for unlocking, and it is available for digital devices that do not require security or for dementia patients. When this option is selected, simply touching any key on the keypad (3) will enter a state where you can operate the digital device immediately without going through the unlocking process. In the case of a door lock, when the door is closed, the lock is locked, but if any key is pressed on the keypad (3), the lock is released.

The unlock password can be set when the second option of the above four options is selected. When the password to be set and the operation formula are inputted, the * and # of the keypad (3) (For about 3 seconds) to complete the setting of the unlocking password, the corresponding password is stored in the memory as the unlocking authentication number.

According to the present invention, the configuration of the unlocking password is implemented by the following methods.

First, it sets a specific fixed number as a password . For users with simple calculations, such as dementia patients or infants, it is also possible to set an unlocking password consisting only of the most commonly used specific numbers.

Second, it is set to the n-th digit of the presentation number . The number displayed in the n-th digit in the eight-digit presentation number appearing in the number display section (2) can be set as a password.

For example, if you set the number displayed on the 5th digit as password, pressing 5 on the keypad (3) for a fixed time (3 seconds) will show 5, which means not 5 but the fifth digit A seat identification mark 22 for indicating a meaning is displayed together. In the drawings of the present invention, '?'

On the other hand, the presentation number can be duplicated except for "0 " In addition, when it is difficult to operate by the presentation number or to indicate another presentation number, a separate re-button may be provided on the keypad so that another number arrangement can be selected.

Third, inputting an operation expression and setting the operation value as a password.

Even if the password is determined only by the digits of the presentation number as described above, if the unlocking process is recorded by the CCTV or the secret camera, the password can be immediately recognized. The present invention provides a method of inputting an operation expression and setting a password as an operation value in order to prevent the password from being grasped even in the above situation.

The construction of the operation expression is made by combining the operation number and the operator, and two or more operators can be input.

Operator uses only the addition (+) input by the * button of the keypad 3, the multiplication (x) input by the 0 button of the keypad, and the subtraction (-) input by the # button, The # button allows the backspace function to be simultaneously performed, but allows the last input value to be erased when the button is pressed for a set time (2 seconds to 3 seconds).

The number of digits to be used in the calculation expression includes at least one n-th digit of the presentation number. When the fixed number is used as the calculation number, only a natural number from 1 to 9 can be inputted, .

⑥ + ⑧, ④-①, 2 + ④, ③ x4-6, ⑨x2 + ①, ⑥ + 3-③

On the other hand, when the multiplication is included in the operator, the operation value to be given to the password takes two digits. If the multiplication is not included in the operator, the absolute value of one digit except the decimal digit is inputted as the operation value.

Expression password 2x3 06 5 + 9 4 2-5 3

Specifically, as illustrated in the above table, the operation value of the operation expression 2x3 is one digit at 6, but since the operator includes the multiplication, the two-digit number 06 is set as the password.

In addition, the result value of the operation expression 5 + 9 is 14, but 4 is set as the password except for the tens digit, and the result value of the operation expression 2-5 is -3, but the absolute value 3 thereof is set as the password.

Fourth, a password can be set by combining two or more of the above first to third methods .

A method of setting the unlock password by the above-described method will be described with reference to the accompanying drawings. For convenience of explanation, the password is an example of four digits, but the number of digits of the password can be added or subtracted by the user.

- If the user's fixed number is 72, and the fourth and eighth number of the presentation number are set to password. (How to configure the unlock password in the first method and the second method)

5 is an exemplary diagram for explaining a procedure for setting a password in the first embodiment. Referring to FIG. 5, a fixed number 7 is input when the cursor 21 is flickered in the first digit of the number display section 2.

In the case of the computer keyboard, the cursor 21 can be moved to the next space by pressing the enter key. However, if there is no physical enter key on the keypad 3 as shown in FIG. 3 When a certain input waiting time elapses, the cursor is automatically blinked in the next column. If the operator buttons (*, 0, #) are not input, the input wait time is set to 1 second. If operator buttons (*, 0, #) are input, the cursor ) Is moved.

Type 2 when the cursor moves to the second column.

When the cursor moves to the third column, press 4 of the presentation number for a predetermined time (3 seconds) so that the seat identification mark 22, which is indicated by a circle in FIG.

When the cursor 21 moves to the fourth column, 8 is pressed for a predetermined time (3 seconds) so that the seat identification mark 22, which is indicated by a circle in FIG.

When the input is completed, press * and # on the keypad (3) simultaneously for a certain time (3 seconds) to complete the setting of the unlock password and the password will be stored in the memory as the unlocking authentication number.

FIG. 6 shows an example of inputting the password set in FIG. 5 by the presentation number.

Referring to the drawing, it is assumed that the presentation number randomly generated in the number display unit 2 is '7274 3754'.

Since the unlocking password set in the above process is 72 ④, the password to be entered is 724, which is a combination of the fixed number 72, the fourth digit of the presentation number 4, and the 8th digit of the presentation number 8.

- When multiplying the fourth and fifth number of the presentation number, subtracting 2, adding 2 to the seventh number, and adding 2 to the eighth number. (A method of inputting an operation expression as a third method and setting the operation value as an unlock password)

7 is an exemplary diagram for explaining an arithmetic expression stored as the unlock password in the second embodiment. An example of setting an arithmetic expression to be inserted in the first two digits of the secret number will be described with reference to the drawings. Press the number 4 keypad (3) for a period of time (3 seconds), press the multiply input button 0 briefly, press the number 5 key for a certain time (3 seconds), press the subtraction input button # Press briefly. Since the multiplication is included in the operator, the operation value of the formula '④x5-2' input by the control unit is inputted as the first two digits of the password.

After the enter key or after 5 seconds, the above formula disappears and the cursor 21 is placed in the first place again. At this time, when the keypad (3) 7 is pressed for a certain time, the addition input button * is shortly pressed, and the number 2 is shortened, the calculated value of the formula ⑦ + 2 is set to the third digit of the password.

Press the enter key again or 5 second after pressing the keypad (8) for a certain period of time, shortly pressing the summing input button *, and then shortly pressing the number 2, the calculation value of the formula ⑧ + 2 is set to the fourth digit of the password, Press # at the same time to finish setting the unlock password.

Fig. 8 shows an example of inputting the password set in Fig. 7 by the presentation number. It is assumed that the randomly generated presentation number in the number display unit 2 is [7274 3754].

Assumption Since the input expression is '④x5-2', the password to be entered in the first and second columns is 10, which is the product of 4th and 4th digit of 3 of 7274 3754 minus constant 2.

Since the second input expression is '⑦ + 2', input the 7th digit of the presentation number 5 and 2 to the third digit of the password, and the 4th digit of the password is 4 If the operation value 6 obtained by adding the constant 2 is input, the digital device 1 is unlocked.

In the present invention, only the smartphone or the door lock is described in order to explain the embodiment. However, the lock setting and releasing method provided by the present invention can also be applied to a password of various Internet sites or a bank security card which require security.

In particular, when cash or money is withdrawn or deposited by inputting a passbook password or a card password from an ATM installed at a place where a lot of people come and go, such as a bank or a convenience store, the user approaches a bad purpose and secretly records the input process with a camera or a micro camera, Even if the process of inputting the password is exposed when the digital device 1 exposed to such a risk is exposed, the present invention does not use the fixed number as the password but the n This is a method that maximizes the security by eliminating the risk of exposing the password because it can not find the set expression even if the input number is exposed to others because it is a method that stores the operation with the digit and the constant.

That is, when a certain mobile phone user inputs a number 35 and unlocks it, the input number 35 is a random number generated from a randomly generated presentation number '7274 3754' ⑦-2, ⑦ because the result is calculated by the input value of 35, even if you carefully watch the process of entering the number of the next person can not even know.

In addition, e-mail and login passwords can be set in this way. In this case, there is an advantage that the server storing the personal information such as the login password can avoid the loss of personal information even if it is hacked.

In addition, since it is composed of one or more operations of addition, subtraction, and multiplication, a password can be set even by using the digits of the presentation number and the fixed number appearing in the number display section (2) for users who are easy to memorize, Therefore, it has an advantage of general versatility.

While the present invention has been described in connection with what is presently considered to be the most practical embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.
