1, a security keyboard input system 100 according to an exemplary embodiment of the present invention includes a server 110 and a secure keyboard input device 130, and includes a server 110 and a secure keyboard input device 130, May be wired or wirelessly connected via network 120. Hereinafter, the operation of each component of the security keyboard input system 100 according to an embodiment of the present invention will be described.

The server 110 provides an online service to the secure keyboard input device 130 connected through the network 120. [ For example, the server 110 may provide an on-line financial service (e.g., a credit card payment service via online, a money transfer service on-line, etc.) to the secure keyboard input device 130. When the secure keyboard input device 130 logs in to the server 110 in order to receive the financial service, the server 110 may request to provide the user's personal information in order to authenticate the user. The server 110 may authenticate the personal information received from the security keyboard input device 130 and provide the online financial service requested by the security keyboard input device 130 when it is determined that the user is a legitimate user. In this case, the server 110 may be a credit card company or a server operated by a bank.

The network 120 may connect the server 110 and the secure keyboard input device 130 in a wired and / or wireless manner. Accordingly, the server 110 and the security keyboard input device 130 can exchange various information through the network 120. [ The network 120 can be applied regardless of the type of a communication network that can connect the server 110 and the security keyboard input device 130 such as the Internet, an intranet, a mobile network, have. Thus, the type of network 120 does not limit the scope of rights of the present invention.

The security keyboard input device 130 can exchange various information with the connected server 110. The security keyboard input device 130 may be any type of device that can be connected to the server 110 such as a mobile terminal, a tablet computer, a laptop computer, a desktop computer, But can be applied irrespective of the type. In particular, the security keyboard input device 130 may generate the information through a security keyboard according to a predetermined method when generating security-required information. When security-required information is generated through a keyboard (hereinafter, referred to as a 'general keyboard') that is basically set in the security keyboard input device 130, keyboard input information is leaked by a spyware or a keystroke logger, Because it can be leaked. Hereinafter, the operation in which the secure keyboard input device 130 generates information requiring security will be described in more detail with reference to FIG.

2 is a block diagram of a security keyboard input device according to an embodiment of the present invention.

2, the security keyboard input device 130 includes a control unit 210, an input unit 220, a display unit 230, and a communication unit 240.

First, the control unit 210 controls the overall operation of the security keyboard input device 130. In particular, the control unit 210 controls each component of the security keyboard input device 130 to perform various operations corresponding to the operation of the user's input unit 220, which will be described later.

The input unit 220 may be an apparatus for generating information on a coordinate value corresponding to a user's operation. For example, if the secure keyboard input device 130 is a device such as a laptop computer or a desktop computer, to which a keyboard device is connected, the input device 220 may be a mouse, a touch pad, or the like. For example, when the security keyboard input device 130 is a device in which a keyboard device such as a mobile communication terminal, a tablet computer, or the like is not connected, the input unit 220 may be a touch screen or the like integrated with the display unit 230 have.

The display unit 230 displays various information output from the control unit 220 so that the user can visually recognize the information. The display unit 130 may be a device such as a liquid crystal display (LCD) or an organic light emitting display (OLED).

The communication unit 240 may be a device connected to the network 120 to exchange various information with the server 110. In particular, the communication unit 240 may transmit information (for example, personal information such as an ID and a password) generated by the control unit 210 to the server 110. Hereinafter, an operation of each component of the security keyboard input device 130 to generate information requiring security through a predetermined security keyboard will be described.

First, the control unit 210 controls the general keyboard to be displayed in a predetermined area (hereinafter, referred to as 'general keyboard area') according to the operation of the input unit 220 of the user. For example, when the security keyboard input device 130 is a mobile communication terminal, the control unit 210 may control the general keyboard to be displayed at the lower end of the entire area of the display unit 230.

Then, the input unit 220 can generate and output coordinate information (hereinafter, referred to as 'general coordinate information') corresponding to the user's general keyboard area operation. When the general coordinate information is inputted, the controller 210 can determine whether or not it corresponds to a preset security order. For example, it is assumed that the first key, the third key, and the sixth key are input through the security keyboard, and the remaining keys are preset to be input through the normal keyboard. At this time, the control unit 210 may determine whether the input general coordinate information corresponds to the first, third, or sixth key. Therefore, if the user inputs personal information composed of 7 keys (for example, 1234567), '1', '3' and '6' can be input through the security keyboard, and '2', '4' 5 'and' 7 'will be able to be input via the normal keyboard.

The control unit 210 may generate an input signal corresponding to the general coordinate information if the input general coordinate information does not correspond to the security order. When the user operates an area corresponding to 'e' through a general keyboard, the control unit 210 can generate an input signal corresponding to 'e'.

The control unit 210 may control the first security keyboard corresponding to the first general coordinate information to be displayed in the first security keyboard area set in advance if the inputted general coordinate information corresponds to the security order. Here, the controller 210 may generate the first security keyboard using the first key group information corresponding to the general coordinate information. For example, when the user operates an area corresponding to 'e' through a general keyboard, the input unit 220 can generate and output general coordinate information corresponding to 'e' The first key group information corresponding to " e "

Here, the first key group information may be a part of the key information included in the general keyboard. When the alphabet key information from A to Z is included in the general keyboard, the first key group information may be a part of the alphabets A to Z. If the ordinary keyboard includes digits 1 to 0 and special characters, the first key group information may be the digits 1 to 0 and some of the special characters.

In addition, the first key group information may be information corresponding to the vertical coordinate information of the general coordinate information. For example, when the general keyboard corresponds to a QWERTY keyboard, the first key group information may include information corresponding to one row in which the vertical coordinate information among the QWERTY keyboards is the same. W, e, r, t, y, u, and u, which are the same as the vertical coordinate information of 'e' of the QWERTY keyboard, when the user manipulates 'e' the first key group information corresponding to i, o, p 'can be read. If the user manipulates' d ', the control unit 210 determines whether the' d 'of the QWERTY keyboard corresponds to' a, s, d, f, g, h, j, k, The first key group information may be read.

In addition, when the general keyboard includes m pieces of key information, the first key group information may be information corresponding to n pieces of key information adjacent to the general coordinate information (note that m is a natural number of 2 or more and n is less than m Of the natural number). It is assumed that a common keyboard, which is a QWERTY keyboard, contains 26 pieces of key information corresponding to a to z, and a user manipulates 'd' in the general keyboard. At this time, the control unit 210 may read 'd' corresponding to 'e', 'f', z, x, s' adjacent to 'd' and 'd' corresponding to general coordinate information as the first key group information. Here, the meaning of 'adjacent' may mean that it is located within a predetermined range centered on general coordinate information. Accordingly, the control unit 210 may read the first key group information using the key information corresponding to the coordinate information within a preset range around the general coordinate information.

As described above, the control unit 210 may read the first key group information corresponding to the general coordinate information, and control the first security keyboard to be displayed on the first security keyboard area. Here, the first secure keyboard area may be a display area different from the normal keyboard area. If the normal keyboard area corresponds to the lower portion of the display area, the first security keyboard area may correspond to the center of the display area or correspond to the middle area.

Thereafter, the input unit 220 may generate and output first security coordinate information corresponding to the first security keyboard operation of the user, and when the first security coordinate information is input, the controller 210 determines whether the security enhanced mode . For example, it is assumed that the third key and the sixth key are preset to be input according to the enhanced security mode. At this time, the controller 210 may determine whether the input first security coordinate information corresponds to the third or sixth key. In the above example (when the personal information to be input by the user is 1234567), the user will be able to input '3' and '6' through the security enhancement mode.

The control unit 210 may generate an input signal corresponding to the first security coordinate information if the input first security coordinate information does not correspond to the security enhanced mode. When the user operates the area corresponding to 'e' through the first security keyboard, the control unit 210 can generate an input signal corresponding to 'e'.

The control unit 210 may control the second security keyboard corresponding to the first security coordinate information to be displayed in the second security keyboard area set in advance if it is determined that the inputted first security coordinate information corresponds to the security enhanced mode. Here, the controller 210 may generate the second security keyboard using the second key group information corresponding to the first security coordinate information. For example, when the user operates the area corresponding to 'e' through the first security keyboard, the input unit 220 can generate and output the first security coordinate information corresponding to 'e' May read the second key group information corresponding to the first security coordinate area (i.e., corresponding to 'e'). At this time, the second key group information may be different in arrangement or information from the key information (first key group information) included in the first security keyboard.

For example, if the first key group information corresponds to 'q, w, e, r, t, y, u, t, y, u, i, o, p ', but their arrangement may be different. If the first key group information is arranged in the order of 'q, w, e, r, t, y, u, i, o, p' y, t, r, e, w, and q '.

As another example, the second key group information may include information that is completely different from the first key group information. The second key group information is' w, s, e, d, f, r 'when the first key group information is' q, w, e, r, t, y, u, . In this case, it is obvious that the second key group information should include 'e' corresponding to the first security coordinate information.

Here, the second security keyboard area may be a display area different from the first security keyboard area. If the first security keyboard area corresponds to the center of the display area, the second security keyboard area may correspond to the middle or upper part of the display area.

Then, the input unit 220 can generate and output second security coordinate information corresponding to the second security keyboard operation of the user, and when the second security coordinate information is inputted, the control unit 210 outputs the second security coordinate information corresponding to the second security coordinate information An input signal can be generated.

Thereafter, if it is determined that the input of personal information is completed, the user can operate the input unit 220 corresponding to the submit button, and the input unit 220 can generate and output the submit signal. The control unit 210 may generate personal information including at least one input signal generated when the submission signal is input, and may output the generated personal information to the communication unit 240. The communication unit 240 can transmit the inputted personal information to the server 110. [ When the user authentication is completed through the received personal information, the server 110 can provide the online service requested from the security keyboard input device 130.

In the above description, it is assumed that only the key corresponding to the security order is input through the security keyboard. However, it is obvious that all the keys may be preset by the security keyboard. In the above description, the second security keyboard is displayed according to the security enhanced mode. However, the security enhanced mode may not be executed according to the embodiment.

As described above, in the security keyboard input device 130 according to the embodiment of the present invention, when the user touches the general keyboard, the first security keyboard and / The user's personal information may not be leaked even if the touch coordinates of the user are leaked. 3 to 7, the operation of the security keyboard input device 130 according to an embodiment of the present invention will be described by way of example.

8 is a flowchart of a method of inputting a security keyboard according to an embodiment of the present invention.

Hereinafter, a security keyboard input method according to an embodiment of the present invention will be described with reference to FIG. Each step to be described below may be performed by the respective components of the secure keyboard input device 130 described with reference to FIG. 2. However, for convenience of explanation, the security keyboard input device 130 performs Will be collectively referred to. Therefore, the subject performing each step performed below can be omitted.

In step S800, the secure keyboard input device 130 displays the normal keyboard in the normal keyboard area according to the operation of the user. For example, when the security keyboard input device 130 is a mobile communication terminal, the general keyboard may be displayed at the lower end of the entire area of the display unit 230. [

In step S805, when the user operates the general keyboard, the secure keyboard input device 130 may generate general coordinate information corresponding to the general keyboard area operation of the user (step S810). The security keyboard input device 130 may determine whether or not the general coordinate information corresponds to a preset security order. For example, it is assumed that the first key, the third key, and the sixth key are input through the security keyboard, and the remaining keys are preset to be input through the normal keyboard. At this time, the secure keyboard input device 130 may determine whether the input general coordinate information corresponds to the first, third, or sixth key.

In step S815, the secure keyboard input device 130 may generate an input signal corresponding to the general coordinate information if the generated general coordinate information does not correspond to the security order number. When the user manipulates the area corresponding to 'e' through the normal keyboard, the secure keyboard input device 130 can generate an input signal corresponding to 'e'.

In step S820, the secure keyboard input device 130 may read the first key group information corresponding to the first general coordinate information if the generated general coordinate information corresponds to the security order number. For example, if the user manipulates an area corresponding to 'e' via a normal keyboard, the secure keyboard input device 130 may generate general coordinate information corresponding to 'e' E., Corresponding to " e "). Here, the first key group information may be a part of the key information included in the general keyboard. When the alphabet key information from A to Z is included in the general keyboard, the first key group information may be a part of the alphabets A to Z. If the ordinary keyboard includes digits 1 to 0 and special characters, the first key group information may be the digits 1 to 0 and some of the special characters. In addition, the first key group information may be information corresponding to the vertical coordinate information of the general coordinate information. In addition, when the general keyboard includes m pieces of key information, the first key group information may be information corresponding to n pieces of key information adjacent to the general coordinate information (note that m is a natural number of 2 or more and n is less than m Of the natural number).

In step S825, the secure keyboard input device 130 may display the first security keyboard in the first secure keyboard area using the first key group information corresponding to the general coordinate information. Here, the first secure keyboard area may be a display area different from the normal keyboard area.

In step S830, the secure keyboard input device 130 may generate first secure coordinate information corresponding to the user's first secure keyboard operation to determine whether the first secure coordinate information corresponds to the enhanced security mode (step < RTI ID = 0.0 > S840). For example, it is assumed that the third key and the sixth key are preset to be input according to the enhanced security mode. At this time, the security keyboard input device 130 may determine whether the input first security coordinate information corresponds to the third or sixth key.

In step S845, the secure keyboard input device 130 may generate an input signal corresponding to the first security coordinate information if the inputted first security coordinate information does not correspond to the security enhanced mode. When the user manipulates the area corresponding to 'e' through the first security keyboard, the secure keyboard input device 130 can generate an input signal corresponding to 'e'.

In step S850, the security keyboard input device 130 may read the second key group information corresponding to the first security coordinate information when it is determined that the input first security coordinate information corresponds to the security enhanced mode. At this time, the second key group information may be different in arrangement or information from the key information (first key group information) included in the first security keyboard.

In step S860, the secure keyboard input device 130 may display the second security keyboard in the second secure keyboard area using the second key group information. Here, the second security keyboard area may be a display area different from the first security keyboard area.

In step S870, the secure keyboard input device 130 may generate an input signal corresponding to the user's second secure keyboard operation (step S880). When the user manipulates the area corresponding to 'e' through the second security keyboard, the secure keyboard input device 130 can generate an input signal corresponding to 'e'.

In step S890, when the submit button is operated according to a user's operation, the security keyboard input device 130 may generate personal information including one or more input signals generated and transmit the personal information to the server 110. [ When the user authentication is completed through the received personal information, the server 110 can provide the online service requested from the security keyboard input device 130.

As described above, in the security keyboard input method according to the embodiment of the present invention, when the user touches the general keyboard, the first security keyboard and / or the second security keyboard are displayed in a new area with different information or layout, Even if the touch coordinates are leaked, the user's personal information may not be leaked.

The above-described security keyboard input method according to an embodiment of the present invention can be implemented as a computer-readable code on a computer-readable recording medium. The computer-readable recording medium includes all kinds of recording media storing data that can be decoded by a computer system. For example, it may be a ROM (Read Only Memory), a RAM (Random Access Memory), a magnetic tape, a magnetic disk, a flash memory, an optical data storage device, or the like. In addition, the computer-readable recording medium may be distributed and executed in a computer system connected to a computer network, and may be stored and executed as a code readable in a distributed manner.
