It should be understood, however, that the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In the drawings, the same reference numbers are used throughout the specification to refer to the same or like parts.

Throughout the specification, when a part is referred to as being "connected" to another part, it includes not only "directly connected" but also "electrically connected" with another part in between . Also, when an element is referred to as "comprising ", it means that it can include other elements as well, without departing from the other elements unless specifically stated otherwise.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a password input device using a count according to an embodiment of the present invention.

At this time, in an embodiment of the present invention, it is assumed that the password input apparatus 100 is a portable communication device (for example, a smart phone).

1, the configuration for providing a password input interface using a count according to an embodiment of the present invention is shown, but other processing units (not shown) may be further included depending on the type of the apparatus.

In addition, the password input device 100 according to an exemplary embodiment of the present invention may be various types of devices other than the portable communication devices, and may further include different processing units depending on the type and purpose of each device. For example, when the secret channel interface providing apparatus 200 is an ATM device used in a bank, a communication module connected to the banking computer, a computer processing unit performing banking computing for each account, And a user interface module for inputting information or outputting a bank processing result.

The password input device 100 using the count according to an embodiment of the present invention includes a password interface management unit 110, a numeric input interface providing unit 120, a decoding unit 130, and a control unit 140.

1 refers to a hardware component such as software or an FPGA (Field Programmable Gate Array) or an ASIC (Application Specific Integrated Circuit), and performs predetermined roles .

However, 'components' are not meant to be limited to software or hardware, and each component may be configured to reside on an addressable storage medium and configured to play one or more processors.

Thus, by way of example, an element may comprise components such as software components, object-oriented software components, class components and task components, processes, functions, attributes, procedures, Routines, segments of program code, drivers, firmware, microcode, circuitry, data, databases, data structures, tables, arrays, and variables.

The components and functions provided within those components may be combined into a smaller number of components or further separated into additional components.

The password interface management unit 110 manages a password interface that arranges a plurality of characters including a reference key along preset array lines and outputs a direction guide indicating the count direction of the array lines. That is, a plurality of characters can be arranged so that a user can input a number replacing a password, and a password interface for outputting a reference key indicating a count start point of arranged characters and a direction guide indicating a counting direction can be managed.

At this time, the character is a visual symbol system for communication, and may include at least one of numerals, Hangul, alphabets, Chinese characters, and the like. The characters are arranged according to a preset array line, and may include at least one of a closed curve, a figure, a dial and a keypad shape in the form of an array line. The array line may also include a reference key to start counting with the character. The reference key may be arbitrarily set by the user using at least one of the character, color, and position, and may store the reference key setting information in the password interface management unit 110. Also, the password-interface managing unit 110 may output a direction guide for guiding the count direction from the reference key as a starting point.

At this time, the password interface management unit 110 can change the character arrangement order or the direction of the direction guide for each input character constituting the password. An example in which the password interface is displayed in the password input device 100 is shown in FIGS. 2, Will be described later with reference to Figs. 3, 4, 5, and 6. Fig.

The number input interface providing unit 120 may provide a number input interface for inputting a number selected by a user. That is, the user can input, through the numeric input interface, a number obtained by counting characters corresponding to the password through the password interface provided by the password interface management unit 110. [

The decoding unit 130 may count the number of characters input by the number input interface along the direction guide from the reference key as a starting point, and store the designated character as a decryption character.

For example, if the counted number is '3', the third character corresponding to the direction guide can be stored as a deciphering character starting from the reference key.

The control unit 140 determines whether the decryption character and the predetermined password coincide with each other, and releases the security if the decryption character is identical. That is, if the predetermined password and the decryption character match, the security is maintained, and if at least one of the predetermined passwords do not match, security can be maintained.

For example, if the decryption character is '1234' and the password is '1234', the security can be turned off. However, if the decryption character is '1236' and the password is '1234', security can be maintained.

2 is a diagram illustrating an example of a dial-type password interface according to an embodiment of the present invention.

2, the password input device 100 may include a password interface 260, a numeric input interface 230, and a password display unit 240. The password interface 260 is configured by randomly arranging numerals '0 to 9' along the dial-shaped array line 210 and a direction guide 220 formed circularly along the array line 210 and a numeral '0' Key 250 as shown in FIG. In addition, in the password interface 260, the direction of the direction guide 220 and the character arrangement order on the arrangement line 210 can be changed for each password entry place.

For example, if the password is set to '1234', you can type:

First, when the number '1' of the first digit of the password '1234' is inputted, the direction key 220 is in the clockwise direction as shown in FIG. 2 (a) When counting to the number '1' as the starting point, it can be confirmed that it is arranged in the fifth position in the order of '3-9-5-6-1'. That is, the count number that replaces the password '1' is '5', and the number '5' can be input to the number input interface 230. The entered number is displayed on the password display unit 240 so that the user can confirm the input and may be displayed as '*' for security reasons.

Next, when the second digit '2' of the password '1234' is input, the reference key 250 '0' is displayed because the direction guide 220 is clockwise, as shown in FIG. 6-1-5-9-4-2-8-2 ", it can be confirmed that they are arranged at the 8th position in the count. That is, the count number that replaces the password '2' is '8', and the number '8' can be input to the number input interface 230. The entered number is displayed on the password display unit 240 so that the user can confirm the input and may be displayed as '*' for security reasons.

When the number '3' of the third digit of the password '1234' is input, the reference key 250 '0' is displayed because the direction guide 220 is clockwise, as shown in FIG. And counts to the number '3' from the starting point, it can be confirmed that it is arranged at the seventh position on the count in the order of '2-8-9-4-6-7-3'. That is, the count number that replaces the password '3' is '7', and the number '7' can be input to the number input interface 230. The entered number is displayed on the password display unit 240 so that the user can confirm the input and may be displayed as '*' for security reasons.

Lastly, when the number '4' of the fourth digit of the password '1234' is input, as shown in FIG. 2D, the direction guide 220 is clockwise, 'And counts to the number' 4 ', it can be confirmed that it is arranged in the order of "2-9-7-5-1-6-3-8-4" on the 9th count. That is, the count number that replaces the password '4' is '9', and the number '9' can be input to the number input interface 230. The entered number is displayed on the password display unit 240 so that the user can confirm the input and may be displayed as '*' for security reasons. In summary, the count number corresponding to the password '1234' is '5879', and the user can input the password by inputting the number counted on the number input interface 230.

The password input device 100 can decrypt a character based on the number input to the number input interface 230. [ That is, the user can count the number of characters entered in the number input interface 230 in the direction guided by the direction guide 220 starting from the reference key 250, and store the designated character as a decryption character.

For example, in FIG. 2A, since the user inputs the number '5' in the number input interface 230, the direction in which the direction guide 220 guides the reference key 250 '0' Quot; 1 " designated as the fifth character of the " 1 " 2B, since the user inputs the numeral '8' in the numeric input interface 230, the eighth in the clockwise direction in which the direction guide 220 guides the reference key 250 ' The designated number '2' can be stored as a decryption character. 2 (c), since the user has input the number '7' in the number input interface 230, the direction guide 220 is guided from the reference key 250 ' The designated number '3' can be stored as a decryption character. 2 (d), since the user has input the number '9' in the number input interface 230, the ninth clockwise direction in which the direction guide 220 guides the reference key 250 ' The designated number '4' can be stored as a decryption character. In summary, as a result of decoding the number '5879' inputted by the user into the number input interface 230, '1234' can be stored as a decryption character.

FIG. 3 is a diagram illustrating an example of two reference keys according to another embodiment of the present invention.

As shown in FIG. 3, the reference key 250 of the password input apparatus 100 according to another embodiment of the present invention can be set by the user at every position. That is, if the number of digits of the password is 4 digits, the user can set the number of the reference keys 250 within 1 to 4, and count the number by applying different reference keys 250 every digit.

For example, when the password is '1234' and the reference key 250 is designated as '0' and '9', the reference key 250 '0' , And the other reference key 250 '9' can be used as the reference key 250 of the passwords '3' and '4'.

First, as shown in FIG. 3 (a), if the reference key 250 '0' is counted in the clockwise direction according to the direction guide 220 starting from the reference key 250 '0' It can be seen that it is arranged at the second position. That is, the count number that replaces the password '1' is '2'. Next, as shown in FIG. 3B, when the password '2' is counted to the number '2' in the clockwise direction according to the direction guide 220 starting from the reference key 250 '0' Quot; 8-5-2 " in the order of the count. That is, the count number substituting the password '2' is '3'. Next, as shown in FIG. 3C, counting from the reference key 250 '9' of the password '3' to the number '3' in the clockwise direction according to the direction guide 220, Quot; 6-5-7-0-1-3 " in the order of the count. That is, the count number that replaces the password '3' is '7'. Next, as shown in FIG. 3 (d), when the password '4' is counted from the reference key 250 '9' to the number '4' in the clockwise direction according to the direction guide 220, 1-3-0-7-6-4 'in the order of the count. That is, the count number that replaces the password '4' is '6'. In summary, the user counts two reference keys 250, which are changed according to the number of digits, from the starting point, and inputs the count number '2376' corresponding to the password '1234' to the number input interface 230.

4 is a diagram illustrating an example of various reference keys according to another embodiment of the present invention.

The reference key 250 can be arbitrarily set by the user using at least one element of characters, colors, and positions, and can store the reference key setting information in the password interface management unit 110.

For example, as shown in FIG. 4A, when the reference key 250 is designated as the number '0 to 9', the numbers '0 to 9' are fixed in a circular shape, The numbers arranged along the reference key 250 may be randomly matched and output.

As shown in FIG. 4B, when a color is designated as the reference key 250, different colors are randomly matched and output for each of the numbers arranged along the array line, Key 250 to input a password.

For example, as shown in FIG. 4 (b), when red is designated as the reference key 250, the number '1' corresponding to red may be the reference key.

4 (c) is an example in which the position is designated by the reference key 250. In FIG. The reference key 250 can be fixed without being moved by setting the position on the interface with the reference key 250 regardless of the character to be arranged.

For example, as shown in FIG. 4C, when the password is '2' and the 3 o'clock direction is set to the reference key 250, the number '0' becomes the reference key 250, Counts to the number '2', and '3 - 6 - 2' means that the third number, that is, the number '3', becomes the count number.

5 is a diagram illustrating an example of various types of password interfaces according to another embodiment of the present invention.

The characters are arranged according to a predetermined array line 210, which may include at least one of a closed curve, a figure, a dial and a keypad shape in the form of an array line 210. Also, it is possible to output the direction guide 220 guiding the count direction with the reference key 250 as a starting point. In this case, the arrangement order of characters or the direction of the direction guide 220 is changed for each input character constituting the password And output.

For example, as shown in FIG. 5 (a), characters may be arranged in the form of a 3x4 keypad as numbers '0 to 9'. That is, the numbers '0 to 9' are randomly arranged in the third column and fourth column according to the arrangement of the 3x4 keypad. Further, as shown in Fig. 5A, the count progression direction can be designated at random and can be indicated through the direction guide 220. [ It can be seen that the directional guide 220 passes the first left column from top to bottom, then from the bottom of the second row to the top, and again from the third row to the top to bottom. Such a sequence may be randomly changed and the user may proceed with the counting along the direction guide 220.

As shown in FIG. 5B, the characters may be arranged in 5X2 cells as the numbers '0 to 9', and the direction guide 220 indicating the direction in which the arranged characters are counted may be randomly output The user can be informed of the count direction. At this time, as shown in FIG. 5 (b), the direction guide 220 repeats the upward and downward directions from the right side to the left side of the password input device 100, and can guide the count direction as an arrow.

6 is an example of a password interface for simultaneously outputting a plurality of array lines according to another embodiment of the present invention.

As shown in FIG. 6, the password input device 100 according to another embodiment of the present invention simultaneously outputs the array line 210 corresponding to each password of the password on one screen to constitute the password interface 260 can do. That is, the array line 210 corresponding to each digit of the password is separated and output, and the output is displayed on one screen, so that the user can simultaneously check and input the count number corresponding to each digit.

For example, as shown in FIG. 6A, four dial-shaped array lines 210, 212, 214, and 216 corresponding to a four-digit password can be simultaneously output. Further, by displaying a number indicating each digit, the user can count the password of the digit.

6 (b) shows an example in which four array lines 211, 213, 215, and 217 arranged in 5x2 cells are output simultaneously and a number indicating each digit is displayed. The user can count the password of each digit along the direction guide 220. [

7 is a flowchart illustrating a method of inputting a password through a password input device using a count according to an embodiment of the present invention.

In step S510, a password interface for inputting a password is output. That is, a password interface including a directional guide for randomly arranged characters and a count direction, and a reference key preset by the user, may be output.

In step S520, the input of the number selected by the user is processed through the numeric input interface.

In step S530, the reference character is counted by the number input by the number input interface along the direction guide from the reference key, and the designated character is stored as the decryption character.

For example, when the user inputs the number '3', the character designated in the direction guided by the direction guide from the reference key can be stored as a decryption character.

In step S540, it is determined whether the decrypted character and the password stored in step S530 are identical.

If it is determined in step S550 that the decrypted character and the password match, the security is released.

On the other hand, if it is determined in step S560 that the decrypted character and the password do not match, the security is maintained.
