Hereinafter, the operating principle of the digital door lock of the present invention will be described.

2 to 4 are schematic views of the keypad for explaining the access authentication method of the password exposure prevention type digital door lock according to the first embodiment of the present invention.

2 to 4 , the keypad 100 is a commonly used keypad in which numbers 0 to 9 and “*” and “#” are arranged in order. However, the keypad 100 of the present invention is characterized in that it is configured to include a horizontal line selection mode and a vertical line selection mode.

When the horizontal line selection mode is selected, the arrangement of numbers in the horizontal line is configured to form one group as shown in FIG. 3 . For example, in the horizontal line selection mode, the first to fourth rows may be configured. In the example of FIG. 3 , in the first row, numbers 1, 2, and 3 are selected as a group, in the second row, numbers 4, 5, and 6 are selected as a group, and in the third row, numbers 7, 8 , 9 are selected as one group, and in the fourth row, *, 0, and # are selected as one group. The arrangement of the numbers may vary, and in some cases, it may be configured to further enhance security by configuring it to be randomly arranged.

On the other hand, when the vertical line selection mode is selected, the arrangement of numbers in the vertical line is configured to form one group as shown in FIG. 4 . For example, in the vertical line selection mode, the first column to the third column may be configured. In the example of FIG. 4 , in the first column, numbers 1, 4, 7, and * are selected as a group, in the second column, numbers 2, 5, 8, and 0 are selected as a group, and in the third column, The numbers 3, 6, 9 and # are selected as a group. The arrangement of the numbers may vary, and in some cases, it may be configured to further enhance security by configuring it to be randomly arranged.

A password unlocking method according to the first embodiment of the present invention will be described using the horizontal line selection mode and the vertical line selection mode.

First, it includes the step of setting a password. The step of setting a password means a general method of setting one specific password in advance and storing it in the digital door lock. Here, the password is preferably set to at least 4 digits, and more preferably set to 6 digits or more to enhance security, but the number of digits is not limited.

When the password is set, the step of determining a specific digit of the set password is included. In this step, for example, by determining the first digit of the set password, it means determining whether the first digit is an even number or an odd number. On the other hand, although the first embodiment has been described as discriminating the first digit, the present invention is not limited thereto, and it is of course possible to discriminate an even number or an odd number of another specific digit.

and selecting a horizontal line selection mode or a vertical line selection mode according to whether a specific digit of the set password is an even number or an odd number. For example, in the present embodiment, if the first digit of the set password is an even number, a horizontal line selection mode may be selected, and if an odd number, a vertical line selection mode may be selected. However, in another embodiment, if the first digit of the set password is an even number, the vertical line selection mode may be selected, and if the number is odd, the horizontal line selection mode may be selected.

For example, unlocking the password when the password is set to "6984" is as follows.

When the first digit of the set password is determined as an even number and the horizontal line selection mode is selected, the first to fourth rows are grouped as in the case of FIG. 3 . However, the groups shown in the drawings are only indicated by virtual box lines for convenience of explanation, and may not be separately indicated in actual use to enhance security.

In this example, since the horizontal line selection mode is selected, the user presses the second line containing "6", the third line containing "9", and the third line containing "8" to unlock the password Press and unlock by pressing the second line containing "4". Here, pressing the second row is characterized in that the digital door lock recognizes that the "second row" is pressed, even if the user actually presses any of the numbers "4, 5, 6" included in the second row.

Therefore, although the set password is "6984", the user can unlock the password by pressing another number included in the line instead of "6984" for the number actually pressed. Because it is unknown, it is impossible to unlock it even if other people or cameras see it.

In addition, in order to further enhance security, it is preferable to further include a keypad random arrangement step of changing the arrangement of the keypad every time the lock is released.

For example, unlocking the password when the password is set to "3842" is as follows.

When the first digit of the set password is determined to be an odd number and the vertical line selection mode is selected, the first to third columns are grouped as in the case of FIG. 4 . However, the groups shown in the drawings are only indicated by virtual box lines for convenience of explanation, and may not be separately indicated in actual use to enhance security.

In this example, vertical line selection mode is selected, so the user presses the third column containing "3" to unlock the password, the second column containing "8", and the first column containing "4" Press and unlock by pressing the second column containing "2". Here again, for example, pressing the second row means that the digital door lock recognizes that the group of “second row” has been pressed even if the user actually presses any of the numbers “2, 5, 8, 0” included in the second row It is characterized by doing.

Therefore, although the set password is "3842", the user can unlock the number by pressing another number included in the column other than "3842", so the user knows the password just by pressing the digital door lock. It has the advantage that it cannot be unlocked even if someone or a camera sees it.

In addition, in order to further enhance security, it is preferable to further include a keypad random arrangement step of changing the arrangement of the keypad every time the lock is released.

Referring to FIG. 5 , the keypad is a commonly used keypad in which numbers 0 to 9 and “*” and “#” are arranged in order.

The keypad in this embodiment is characterized in that it is configured to include three selection modes: a basic selection mode, a horizontal line selection mode, and a vertical line selection mode. It is characterized by providing that one of the modes can be selected.

Since the horizontal line selection mode and the vertical line selection mode have the same basic operating principles as those described in the first embodiment, a basic description will be omitted. The basic selection mode means the most common method of pressing the set password as it is.

As described above, a password unlocking method according to the second embodiment of the present invention will be described using the basic selection mode, the horizontal line selection mode, and the vertical line selection mode.

First, it includes the step of setting a password. The step of setting a password means a general method of setting one specific password in advance and storing it in the digital door lock. Here, the password is preferably set to at least 4 digits, and more preferably set to 6 digits or more to enhance security, but the number of digits is not limited.

mode selection step. The mode selection step means that the user selects one of a basic selection mode, a horizontal line selection mode, and a vertical line selection mode for unlocking.

For example, in FIG. 5 , the user may press one of the numbers “2, 4, 5, 6, 8” to select a mode. In the second embodiment, pressing "2" or "8" selects the horizontal line selection mode, and pressing "4" or "6" may be configured to select the vertical line selection mode. When the user presses "5", the default selection mode is selected. However, the basic setting method for selecting the selection mode may be changed and may be preset so that another selection mode is selected by pressing another number.

When the user selects one mode, a keypad random arrangement step in which the numbers on the keypad are randomly arranged as shown in FIG. 6 is performed.

Then, the user performs a step of unlocking the password according to the mode selected by the user.

A case in which the set password is "2569" will be described as an example of a password unlocking method according to the second embodiment.

The user selects one of "2, 4, 5, 6, 8" in FIG. 5 for the mode selection step. However, the groups shown in the drawings are only indicated by virtual box lines for convenience of explanation, and may not be separately indicated in actual use to enhance security.

In the example of FIG. 6, as a horizontal line selection mode, "5, 9, 3" is grouped into a group in the first row, "6, 1, 4" is grouped in a group in the second row, and "2, 8, 7" is grouped as a group in the second row. Grouped in the third row, and "*, 0, #" is grouped in the fourth row.

Now, in order to unlock the password, the user presses the third line containing "2" in the set password "2569", presses the first line containing "5", and presses the second line containing "6" You can unlock the password by pressing and pressing the first line containing "9".

Therefore, although the set password is "2569", the user can unlock the actual password by pressing another number included in the line other than "2569". It has the advantage that it cannot be unlocked in the next order even if other people or cameras see it because it is unknown.

If the user wants to select the vertical line selection mode, the user selects the vertical line selection mode by pressing "4" or "6", and then the keypad of the digital door lock is randomly arranged as shown in FIG. vertical line selection mode".

In the example of FIG. 6 , as a vertical line selection mode, "5, 6, 2, *" is grouped into a group in the first column, "9, 1, 8, 0" is grouped in a group in the second column, and "3, 4, 7" , #" is grouped in the third column.

Now, in order to unlock the password, the user presses the first column containing "2" in the set password "2569", presses the first column containing "5", and presses the first column containing "6" You can unlock the password by pressing and pressing the second column containing the "9".

Therefore, although the set password is "2569", the user can unlock the actual password by pressing another number included in the column other than "2569". The advantage is that it cannot be unlocked in the next order even if other people or cameras see it because it is unknown.

In addition, if the user wants to select the basic selection mode, the user selects the basic selection mode by pressing "5", and then the keypad of the digital door lock is randomly arranged as shown in FIG. prepared as

In the basic selection mode, the user can unlock the password by pressing "2569", which is the set password, as it is to unlock the password. This has an advantage in that it provides the user's choice so that they can easily unlock it by simply pressing the password that is set easily when there is no security threat. If used, the number of cases increases significantly, making it impossible for others to verify the actual password.
