2, the security key input system according to the present invention includes a keypad input device 100 and a portable terminal 300. [

At this time, the keypad input device 100 generally refers to a device for inputting a security key (password) such as an ATM device, a door lock, and the like.

The keypad input device 100 includes a keypad input unit 110, a control unit 120, and an NFC recognition unit 130.

The keypad input unit 110 is an input window provided in the keypad input device 100 and receives a security key from a user through the keypad input unit 110. [ In general, the keypad input unit 110 may include a touch panel, but a physical push type input device may be applied.

On the other hand, the controller 120 receives the one-time keypad from the portable terminal 300, decrypts the secret key input from the user through the one-time keypad, and determines whether the input secret key is identical or not.

The controller 120 outputs a keypad for receiving a secret key from the user to the keypad input unit 110. The keypad outputs a secret keypad having an identification mark removed (not shown) on the keypad.

Meanwhile, the one-time keypad is a keypad randomly arranged at an arrangement position, which will be described in detail.

The NFC recognizer 130 receives the one-time keypad generated from the portable terminal 300 by proximity communication with the NFC recognition module 330 included in the contacted portable terminal 300.

The portable terminal 300 includes a display module 310, a controller 320, and an NFC recognition module 330.

The NFC recognition module 330 transmits the one-time keypad to the keypad input device 100 as described above, and may be an NFC module provided in a smart phone.

Meanwhile, the controller 320 includes a one-time keypad generating unit 322 for generating a one-time keypad.

The one-time keypad generation unit 322 generates a keypad having random arrangement order, and generates and provides a new one-time keypad according to a user's creation command.

The controller 320 outputs the one-time keypad generated through the one-time keypad generator 322 through the display module 310.

In this case, the display module 310 may be an output window provided in a smart phone.

3, the portable terminal 300 includes a keypad input device 100, a management server 200, and a portable terminal 300. The keypad input device 100, the management server 200,

That is, another embodiment of the present invention is for applying the present invention to a portable terminal without an NFC module, and a one-time keypad generated in the portable terminal 300 is transmitted to the keypad input device (100).

For this, the keypad input device 100 includes a keypad input unit 110, a control unit 122, and a communication module 132.

The keypad input unit 110 is an input window provided in the keypad input device 100. The control unit 122 receives a one-time keypad through a management server 200 to be described later, Or the input key input from the input key.

The communication module 132 is a communication module that can be connected to the management server 200 to be described later on-line, and wireless communication such as Wi-Fi can be applied as well as general wired communication.

Meanwhile, the management server 200 transmits the one-time keypad generated in the portable terminal 300 to the keypad input device 100, so that the keypad input device can perform communication It is possible to omit it.

The portable terminal 300 includes a display module 310, a controller 320, and a communication unit 332.

The communication unit 332 is connected to the management server 200 online and provides the one-time keypad generated by the controller 320 to the keypad input device 100. [

The controller 320 includes a one-time keypad generator 322 to generate a one-time keypad through the one-time keypad 322 and output the generated one-time keypad through the display module 310 do.

Hereinafter, the one-time keypad and the security keypad will be described in detail.

The one-time keypad is created and disappeared at one time with a keypad in which the arrangement positions of the keypads are randomly arranged by a random algorithm.

In other words, referring to a general 4 by 3 array keypad, for example, a keypad in which 1 to # are not sequentially arranged in each input key, and random input commands are arranged in each input key.

Such a one-time keypad may be generated by a user's specific input command.

That is, as shown in FIG. 4, a specific type of touch input (circular) may be input to the keypad input window, or a certain type of motion (wiggle) may be input to generate the array key in a shuffle form have.

On the other hand, the one-time keypad may be generated by a random algorithm, as described above, but may be generated by an arbitrary operation of the user.

That is, as shown in FIG. 5, in the basic keypad state, the user can drag and change the position of each array key, thereby creating a desired one-time keypad.

Accordingly, the user can use his / her preferred one-time keypad, and the one-time keypad generated by the user can be stored in the portable terminal for a certain period of time (before the user changes).

At this time, the one-time time of the one-time keypad does not mean that the keypad arrangement is changed every time it is used, but it means that it is changed after a certain period of time.

On the other hand, the one-time keypad may be composed of numerals and a series of symbols (*, #) as a separator, like a general keypad. However, as shown in FIG. 6, have.

In FIG. 6, the colors are distinguished by differences in shades due to the characteristics of the patent specification.

Of course, the size of the keypad may be generally 4 by 3, but it is also possible to enlarge the arrangement to improve security.

That is, in general secret key input, it is necessary to increase the length and kind of the secret key to increase the security. Therefore, it is difficult to memorize the secret key of the user, which causes inconvenience in use. The security of the keypad can be improved by increasing the size of the keypad while maintaining the secret key of the keypad. Therefore, there is no inconvenience in use even if the security is enhanced.

Meanwhile, the security keypad output to the keypad input device 100 is the same as that of the one-time keypad as shown in FIG. 7 but refers to a keypad in which the identification mark is deleted.

Hereinafter, the security key input method according to the present invention will be described in detail with reference to the accompanying drawings.

8 is a flowchart illustrating a security key input method according to an embodiment of the present invention.

As shown in the figure, the security key input method according to the present invention starts with a user creating a one-time keypad through the portable terminal 300 (S110).

At this time, the one-time keypad may be randomly generated by shuffling by command input of the user, or may be generated by an arbitrary arrangement operation of the user.

Of course, in the case where the stored one-time keypad is stored by arbitrary arrangement operation of the user, it is also possible to read and use the stored one-time keypad.

Then, the portable terminal 300 is contacted to the keypad input device 100 to recognize short-range wireless communication (S110).

7, the user inputs a card into a desired transaction and inputs a security key to the keypad input device 100, as in the normal method. In other words, when the keypad input device 100 is an ATM device as shown in FIG. 7, (Or reads) a one-time keypad on the portable terminal 300 and contacts the portable terminal 300 to the NFC recognition unit 130 provided in the keypad input device 100. [

When the keypad recognition apparatus 100 and the portable terminal 300 are recognized by the short range wireless communication (NFC), the one-time keypad generated by the portable terminal 300 is transmitted to the keypad input apparatus 100 , So that the one-time keypad is synchronized.

According to another embodiment of the present invention, the transmission of the one-time keypad is performed by the communication unit 332 and the communication module 132 by the Internet without contacting the keypad recognition apparatus 100 and the portable terminal 300 .

Then, the portable terminal 300 outputs the generated one-time keypad through the display module 310 (S150).

Then, the portable terminal 300 counts the time (S160), outputs the one-time keypad for the set time, and then terminates the one-time keypad output (S160).

It is also possible to delete the one-time keypad after the output of the one-time keypad is terminated (S170).

In operation S210, the keypad input device 100 receiving the one-time keypad from the portable terminal 300 outputs an input window including only the keypad divided area to the keypad input unit 110 and receives a key input from the user.

7, only the key input window without numbers or symbols is displayed on the keypad input device 100, and the user confirms the one-time keypad through the portable terminal 300, and the keypad input unit 110 ) To enter the security key.

Hereinafter, a key of an input window in which a number or symbol is not displayed is called a null key.

Meanwhile, the keypad input unit 110 output through the keypad input device 100 may output an input window according to various embodiments.

That is, although the keypad input unit outputs an input window displaying only the input area, according to another embodiment, an input window displaying some digits or symbols may be output. Accordingly, the user can easily recognize the arrangement of the one-time keypad displayed on the portable terminal 300 by matching with the keypad input unit 110.

At this time, it is preferable that the number or number of symbols displayed on the keypad input unit 110 is set to be less than the set number of security keys.

That is, when the number or the number of symbols displayed on the keypad input unit 110 is equal to or greater than the set number of security keys, all the security keys to be input may be displayed on the keypad input unit 110, thereby preventing this.

For example, in the case of an input window composed of 12 zones, if the security key is set to 4 digits, there is a possibility that all the security keys to be input with a probability of about 1/11880 are displayed on the keypad input unit 110. In order to prevent this, the number or the number of symbols displayed on the keypad input unit 110 is preferably set to be less than the set number of security keys.

Meanwhile, when the security key input of the user is recognized, the keypad input device 100 reads (converts) the input security key according to the generated arrangement of the one-time keypad (S220).

Thereafter, the keypad input device 100 determines whether the input security key and the setting code match (S240).

Here, the setting code means a set password. In the case of an ATM, the setting code is read when a user's card is inserted, and may be a password set in the case of a door lock.

In step S240, it is determined whether the input security key is identical to the setting code.

Here, whether or not the input security key and the setting code match each other may be performed for each key input, or may be performed after all security keys of a predetermined length are input.

The output of step 240 may be an output through a display or an output through a sound. For example, when the security key input matches the setting code, the input key position is output as a specific color (green). If the security key input is an unmatched input, the input key position is output as another color (red) It is possible to immediately know the input / output of the input.

Hereinafter, a security key input system and method according to another embodiment of the present invention will be described.

9 is a block diagram illustrating another embodiment of a security key input system according to the present invention.

9, the security key input system according to the present invention further includes a storage unit 140 and a storage module 340 in the keypad input device 100 and the portable terminal 300, respectively, .

In another embodiment of the present invention, after the portable terminal 300 generates and shares a one-time keypad through recognition by the keypad input device 100 and the NFC, the portable terminal 300 stores the one-time keypad in the storage unit 140 Module 340, respectively.

Specifically, another embodiment of the present invention starts with the portable terminal 300 recognizing the keypad input device 100 by NFC.

Then, the portable terminal 300 generates a one-time keypad from the one-time keypad generator 322, and transmits the generated one-time keypad to the keypad input device by NFC communication.

Of course, at this time, the one-time keypad may be generated by the user's command and shared by NFC communication.

The one-time keypad is stored in the storage unit 140 of the keypad input device 100 and the storage module 340 of the portable terminal 300, respectively.

Then, after the user inputs the secret key through the keypad input unit 110 of the keypad input device 100 and the security is released, the one-time keypad stored in the storage unit 140 is deleted and is destroyed.

When a new one-time keypad is generated in the portable terminal 300 through a user's input command or NFC recognition, the newly generated one-time keypad is stored in the storage unit 140 of the keypad input device 100 through NFC communication , The storage state is maintained until security is released by user secret key input.

According to another embodiment of the present invention, in another embodiment of the present invention, the time difference between the generation of the one-time keypad and the secret key input, and the spatial difference between the keypad input device 100 and the portable terminal 300, can do.

That is, once the one-time keypad is generated and stored in the keypad input device 100 and the portable terminal 300, even if there is a time difference or a secret key input is not carried by the portable terminal 300, ) With the help of the holder, the secret key can be entered one time.

Another embodiment of the present invention has a great effect when the door lock is applied to the keypad input device 100.

For example, if a one-time keypad is already generated and stored in the keypad input device 100 and the portable terminal 300, if the holder of the portable terminal 300 (the landlord, etc.) goes out, The owner of the portable terminal 300 can inform the other person of the input position and the order of the keypad so that the door lock can be canceled.

In this case, since the stored one-time keypad is extinguished after the security of the door lock is released by one-time, the security can not be released even if the key input at the same position is made, thereby preventing the possibility that the password itself is leaked to another person.

The embodiments of the present invention may be combined with other embodiments of the present invention.

That is, in general, the portable terminal 300 and the keypad input device 100 are used to generate a one-time keypad and input a secret key in a one-time manner as in a specific embodiment or another embodiment of the present invention, And stores it in the storage unit 140 and the storage module 340. It is possible to notify the location and order of the secret key input by the stored one-time keypad only when it is necessary to permit access to the other person at the remote place.

Of course, also in this case, after the security release is approved, the one-time keypad stored in the storage unit 140 is deleted.

Meanwhile, the present invention can be implemented by varying the detailed configuration according to the target device of the keypad input device.

For example, the keypad input device may be a computer terminal.

In this case, the keypad input unit may include a display device (monitor) and a human interface device (mouse, etc.) applied to the computer terminal, and the one-time keypad generated in the portable terminal may be shared with the computer terminal by wire / .

Meanwhile, when the keypad input device is provided with a separate output device, the present invention can be implemented without including the portable terminal.

For example, when the keypad input device is an ATM device, the keypad input device includes a control unit including a one-time keypad generation unit, and an output unit.

The one-time keypad generating unit generates a one-time keypad each time a user inputs a security key, and the output unit prints the generated one-time keypad on an output medium such as print paper and provides the printed one to the user.

That is, when a user inputs a secret key while using the keypad input device (ATM), the keypad input device generates a one-time keypad through the one-time keypad generation unit, prints it on paper through the output unit, can do.

Here, in order to enhance the security of the present invention, the output unit may output the output paper so that the printed surface on which the one-time keypad is printed faces downward, or the output paper is discharged in a dried form, It is not possible to recognize the printed paper.

Thereafter, the keypad input device outputs a security keypad whose identification mark is deleted on the keypad input unit, and the user inputs a key corresponding to his / her password (security key) according to the one-time keypad printed on the output paper, Lt; / RTI >

Accordingly, the user can input the security key by using the one-time keypad without having a separate portable terminal.

Of course, such an embodiment of the present invention can be applied to various devices (door locks, safes, etc.) provided with output means as well as ATM devices.

It is to be understood that the invention is not limited to the disclosed embodiment, but is capable of many modifications and variations within the scope of the appended claims. It is self-evident.

The present invention relates to a security key input system and method for enabling a user to receive a security key from a user in a secured state using a portable terminal, Even if the password inputting state of the keypad input device is leaked, there is no fear of password leakage, and the password is not leaked even if the portable terminal is hacked by the electronic means.
