Description

PIN information input device and its control method {INPUT APPARATUS OF PIN INFORMATION AND CONTROL METHOD THEREOF}

The present invention relates to a PIN information input device and a control method thereof, and more particularly, to a pin information input device using position-related information, which is indirect information related to pin information, and a control method thereof.

In general, the switch pin [Personal Identification Number (SwitchPIN)] method is an authentication technique using a switchable keypad.

That is, for user authentication, the keypad for inputting a personal identification number (i.e., a PIN code) is a specific key (e.g., the'show' key) in addition to the numeric keys displaying numbers from 0 to 9, respectively. ) Is provided, and this'show' key is a key for showing a keypad in which numeric keys are arranged randomly differently from the initial arrangement of numeric keys.

Therefore, whenever the user presses the'show' key, the keypad alternately displays a randomly arranged numeric key arrangement and an initial numeric key arrangement.

Accordingly, SwitchPIN is a method in which the user stores information on the arrangement of randomly arranged numeric keys when the'show' key is pressed, so that pin information is input in an initial state indicating the initial arrangement of numeric keys.

For example, assume that you input 4 numbers, 1, 5, 7, and 9 as pin information.

The user first touches the'show' key to display a state in which the keypad has a numeric key arrangement different from the initial state of Fig. 1A (e.g., this state is referred to as'random arrangement state') (see Fig. 1B). , In this random arrangement state, the number of positions 6, 7, 4, 9 corresponding to the pin information 1, 5, 7, 9, respectively, is memorized. After that, press the'show' key again to make the state of the keypad to the initial state as shown in Fig. 1c, and then input the memorized numbers 6, 7, 4, and 9 to enter the pin information (1, 5, 7, 9 ) To be entered

FIG. 1D shows another example of a random arrangement state in which the keypad has a different numeric key arrangement than that of FIG. 1B when the'show' key is pressed in the initial state of FIG. 1A. Therefore, in FIG. 1D, the number of positions corresponding to each of the pin information 1, 5, 7, 9 is 9, 2, 3, 5, so the user remembers these 9, 2, 3, 5 and When this number (9, 2, 3, 5) is entered on the initial screen, it is recognized that the correct pin information (1, 5, 7, 9) has been entered.

1E is an example of a keypad in which an alphabet is used instead of a number, and an alphabet key is provided in which each predetermined alphabet is displayed instead of a number key. The user can set pin information as an alphabet instead of a number. .

On the other hand, when a component is referred to as being "directly connected" or "directly connected" to another component, it should be understood that there is no other component in the middle.

Then, a pin information input device and a control method thereof according to an embodiment of the present invention will be described with reference to the accompanying drawings.

First, a pin information input device 100 according to an embodiment of the present invention will be described in detail with reference to FIG. 2.

In this example, the pin information input device 100 may be a portable terminal or a stationary terminal such as a mobile phone, a smart phone, or a tablet personal computer.

2, the pin information input device 100 is connected to the communication unit 110, the user input unit 120, the control unit 130 connected to the communication unit 110 and the user input unit 120, and the control unit 130 An output unit 140 and a storage unit 150 connected to the control unit 130 are provided.

In this case, the components 110-150 shown in FIG. 2 are not essential to the pin information input device 100, and thus at least one component other than the components 110-150 is additionally provided or At least one of the components may be omitted.

The communication unit 110 communicates between the pin information input device 100 and an external communication system (not shown), or between the pin information input device 100 and a network in which other electronic devices such as a portable terminal or a fixed terminal are located. It contains one or more modules that make it possible.

For example, as shown in FIG. 2, the communication unit 110 includes a mobile communication module 111, an Internet module 112, and a short-range communication module 113.

The mobile communication module 111 wirelessly transmits and receives a signal (ie, a radio signal) with at least one of a base station, an external terminal, and a server on a mobile communication network. The wireless signal may include a voice call signal, a video call signal, or various types of data according to transmission and reception of a short message or a multimedia message.

The Internet module 112 refers to a module for wireless or wired Internet access, and the Internet module 112 may be embedded or external to the pin information input device 100.

As the Internet technology, WLAN (Wireless LAN) (WiFi), Wibro (Wireless broadband), Wimax (World Interoperability for Microwave Access), or HSDPA (High Speed Downlink Packet Access) may be used.

The short-range communication module 113 refers to a module for short-range communication.

As a short-range communication technology, Bluetooth, Radio Frequency Identification (RFID), infrared data association (IrDA), Ultra Wideband (UWB), or ZigBee may be used.

In an alternative example, the communication unit 110 may omit at least one of these 111-113 or may include at least one additional communication module.

The user input unit 120 generates a signal related to an input operation, such as pin information for the operation of the pin information input device 100 or a command input for operation control, and outputs the signal to the control unit 130.

The user input unit 120 may include an input unit (eg, a touch pad) using a touch sensor or the like, or an input unit (eg, a key pad) operated by a physical force.

The user input unit 120 of this example performs input for setting pin information and input of location-related information, which is indirect information corresponding to the set pin information.

In this example, the pin information set by the user consists of one reference code and at least one pin code.

The reference code serves as a reference point for the user to recognize indirect information on each pin code, and is composed of alphabetic characters, figures, or special characters.

In addition, at least one pin code is substantially actual pin information set by a user, and the at least one pin code may consist of at least one of numbers, alphabetic characters, and special characters.

At this time, information of at least one pin code (ie, information indicated by the pin code) may be different or at least two of them may be the same.

As already described, the indirect information in this example is location-related information related to pincodes, consisting of information in which location-related information related to each pincode is sequentially arranged (e.g., numeric information), and location information for each pincode. Or a position value.

The location information for each pincode is the matrix location of each pincode (ie, the x-axis location and y-axis location (xy location) or the y-axis location and x-axis location (yx location)).

At this time, the location information of each pin code is arranged in the same order (ie, xy or yx). Hereinafter, the order in which the location information of each pincode is arranged is referred to as'array order'.

When the location-related information related to each pin code is a location value, it may be a sum value of location information of each pin code. For example, when the location information of one pin code is (13), the location value of this pin code becomes '4(=1+3)'.

The controller 130 controls the operation state of the output unit 140 by using a signal applied through the user input unit 120, and processes and controls data generated during the operation of the pin information input device 100.

The operation of the control unit 130 will be described in detail later.

The output unit 140 is for generating a time-related output, and outputs an image corresponding to the image data output from the control unit 130 according to the operation of the control unit 130 that controls the operation of the pin information input device 100. A display module to display on the screen may be provided.

Accordingly, the output unit 140 outputs a pin information setting screen, which is a screen for setting pin information of the pin information input device 100, and an indirect information input screen, which is a screen for inputting location-related information of the pin information.

The display module provided in the output unit 140 may include a pixel area in which a plurality of pixels are arranged in a matrix structure, a liquid crystal display, an organic light emitting diode display, and a flexible display module. It may be at least one display device from among a flexible display and a 3D display.

The display module of the present example may be a touch screen provided with a structure for displaying an image as well as a component (hereinafter referred to as a'touch sensor') for detecting a touch motion. In this case, the output unit 140 ) Also includes a structure of the user input unit 120.

The touch sensor of this example may be a sensor using pressure, static capacitance, or temperature.

In this example, it is assumed that the output unit 140 is formed of a touch screen, and the operation of this example will be described.

Accordingly, as shown in FIG. 4A, an indirect information input screen on which indirect information is input is output to the output unit 140 made of a touch screen, and an example of an indirect information input screen is a pin guiding the input of a pin code. It includes a code input guide 121 and an indirect information input unit 122 for inputting indirect information corresponding to each pin code.

The pin code input guide unit 121 includes a plurality of areas 1211 partitioned in a matrix structure as shown in FIG. 4A.

In the plurality of areas 1211, information on reference code candidates is displayed, arranged in a matrix structure, and information on reference code candidates is displayed (hereinafter referred to as'reference code candidate area') and each component of the pin code candidate group It consists of a region (hereinafter referred to as a “pincode candidate group region”) in which information on the in-pincode candidate is displayed and arranged in a matrix structure.

In this case, since the reference code candidate includes a reference code selected by a user, the reference code candidate includes a reference code candidate having the same information as the reference code.

The number of reference code candidate regions is the same as the number of predetermined reference code candidates (e.g., 6), and the information displayed in each reference code candidate region (that is, the key value displayed in the reference code candidate region) is also the information of each reference code candidate. Same as (Example, A, B, C, D, E, F). Accordingly, all of the information displayed in each criterion code candidate area is different.

The pincode candidate group is a set of pincode candidates each selected for the user, and includes at least one pincode candidate having the same information as each pincode.

In this case, the pincode candidate group displayed in the pincode candidate group area may be a set or may be formed of a plurality of sets. Therefore, when there is only one set of pincode candidate groups, all of the pincode candidate information displayed in the pincode candidate group regions is different.

However, when there are multiple sets (eg, 3) of pincode candidate groups displayed in the pincode information candidate group area, the number of areas displaying the same information in the pincode candidate group area is plural (eg, 3). Becomes.

For example, when the pincode candidate group consists of numbers 0-9, and two sets of pincode candidate groups (i.e., the first set of 0-9 and the second set of 0-9) are displayed in the pincode candidate group area , In the pincode candidate group area, there are 10 areas for the first set and 10 areas for the second set, and the total number of pincode candidate group areas is 20.

At this time, the 10 areas for the first set display a different number among the numbers 0-9, and the remaining 10 areas for the second set also display a different number among the numbers 0-9. . Therefore, when two sets of candidate groups are displayed in the pincode candidate group area, there are two pincode candidate group areas that display the same information (eg, 9).

The pin code input guide unit 121 shown in FIG. 4A is an example.

As shown in Fig. 4A, the types of reference code candidates are alphabetic characters, the number of reference code candidates is 6, and information (ie, values) of these reference code candidates is A, B, C, D, E, F. to be.

Therefore, one of A, B, C, D, E, and F is displayed in each reference code candidate area, and three sets are displayed in the pin code candidate group area, so that three pin code candidates displaying the same information are provided. Can be seen. It can be seen that the pincode input guide unit 121 has a total of 36 areas divided into a matrix structure (6×6 structure).

In this example, the type, number and information of reference code candidates displayed on the pin code input guide unit 121 and the type, number and information of pin code candidates are already stored in the storage unit 150.

The indirect information input unit 122 is a part for inputting indirect information corresponding to a pin code, and includes a number key and a delete key in which numbers 0 to 9 are respectively displayed.

Unlike the example shown in FIG. 4A, when the output unit 140 does not partially perform the functions of the user input unit 120 such as a touch screen and is formed of a separate component from the user input unit 120, the indirect information input unit ( 122) is provided in the user input unit 120.

In the case of inputting a pin code using the pin code input guide unit 121 having this structure, the user first checks the positions of the reference code candidate and the pin code candidate displayed on the pin code input guide unit 121, and sets the pin code by himself. Check the location of one reference code and each pin code.

Then, the user checks the location-related information for each pin code located at the closest distance (ie, location) in the x-axis direction and y-axis direction from the checked reference code.

Then, the user sequentially inputs location-related information for each pin code according to a predetermined arrangement order using the indirect information input unit 122 to sequentially input indirect information for each pin code.

The controller 130 determines indirect information (eg, input indirect information) sequentially input by the user using a touch signal according to the touch position of the indirect information input unit 122 or a signal applied from the user input unit 120 , The determined input indirect information is compared with the set indirect information stored in the storage unit 150. When input indirect information identical to the setting indirect information is input, the controller 130 determines that the correct indirect information for the pin code has been input.

The control unit 130 already knows the pin information determined by the user using the information stored in the storage unit 150, and the pin code input guide unit that is currently output through the output unit 150 under its own control ( 121), the pincode candidate information displayed in each area, and the reference code candidate information are known.

For this reason, after determining the location-related information for each pin code, the control unit 130 arranges the determined location-related information in the order of the arrangement of the pin codes and stores it in the storage unit 150 as setting indirect information for the pin information. do.

That is, the control unit 130 determines the location-related information of the pincode candidate region, which is located at the nearest position based on the reference code candidate region having the same information as the reference code, and has the same information as the pincode, among the reference code candidate regions. Position-related information for each pin code is determined, and the position-related information determined in order in the order of the arrangement of the pin codes is arranged and stored in the storage unit 150 as setting indirect information.

In this case, when the location-related information is location information, the control unit 130 determines the setting indirect information according to the arrangement order (xy order or yx order) stored in the storage unit 150.

In addition, when the location-related information is location information, if the number of pincode candidate areas separated from the reference code candidate area in which the reference code is displayed in the x-axis direction is 0 (that is, the reference code candidate area in which the reference code set for the user is located) (Hereinafter referred to as'reference code area') when information of the corresponding pin code is displayed in the pin code candidate area immediately above or below] or when the number of pin code candidate areas separated in the y-axis direction is 0 (that is, the reference When pincode information is displayed in the pincode candidate area immediately left or right of the code area), the location information of the road in the x-axis direction and the location information in the y-axis direction are respectively '0'.

In this case, since '0' can be omitted according to the setting condition by the user's setting operation, the setting indirect information does not include '0'. As an example, when the location information for each pin code is (01), (11), (23), and (40), the setting indirect information for the pin code is '111234'.

In addition, in the case of this example, if there are a plurality of pincode candidate regions that are located in the closest position to the reference code candidate region having the same information as the reference code and have the same information as the corresponding pin code, As for the location information of the code, all location information on the pincode candidate region having the same information as the corresponding pincode is adopted.

As an example, there are a total of two pincode candidate regions (e.g., information on the corresponding pincode candidate region is number 1) located at the same distance from the reference code region, and the location information of these two pincode candidate regions is (12 ), (21), both numeric arrays including these two positional information are stored as setting indirect information.

To take a more specific example, the location information for the pin code is (01), (12) , (23), (40) or (01), (21) , (23), (40), and these location information In the second pin code has location information of the same distance from the reference code area. Accordingly, since the controller 130 stores both '01 12 2340' and '01 21 2340' as setting indirect information, the user must sequentially input one of these numbers. In this case, when '0' is a setting condition to be omitted, the setting indirect information is '1 12 234' or '1 21 234'.

In addition, although not shown in the drawings, the output unit 140 outputs a pin information setting screen for setting pin information through the control of the controller 130 as described above.

In this case, the pin information setting screen may also be divided into a plurality of areas similar to the pin code input guide unit 121.

Each partitioned area also has a pincode candidate group area and a reference code candidate area. In this case, the types of pincode candidates displayed in the pincode candidate group area and information on each candidate are the same, but an area displaying the same information may not exist. In this case, the number of pincode candidate group areas on the pin information setting screen is smaller than the number of pincode candidate group areas on the indirect information input screen.

In the reference code candidate area on the pin information setting screen, information on the reference code candidate displayed in each area is the same as information displayed on the indirect information input screen.

4B is a diagram showing an example of a partition state of the pincode input guide 121 when the number of pincode candidate group regions exceeds three sets.

As previously described, the storage unit 150 is a storage medium that stores data required for the operation of the control unit 130 or data generated during operation, and may be formed of a memory or the like.

Accordingly, the storage unit 150 of this example includes pin information determined by a user, an arrangement order of location information for each pin code, at least one setting indirect information for the currently output indirect information input screen, and the type of the reference code candidate. , The number and type of reference code candidates, the type of pin code candidate, the number and type of reference code candidates, and the like are stored.

Next, an operation of the pin information input device having such a structure will be described in detail with reference to FIG. 4A together with FIGS. 3A and 3B.

As already described, the output unit 140 has an input function as well as an image display function.

First, a method of setting pin information in the pin information input device 100 according to an embodiment of the present invention will be described with reference to FIG. 3A.

When the operation of the pin information input device 100 starts due to the supply of power required for the operation, the operation of the control unit 130 also starts.

Accordingly, the control unit 130 first reads a signal input from the user input unit 120 (S12), and determines whether a setting command for setting pin information has been input (S13).

When a pin information setting command is input from the user input unit 120 (S13), the control unit 130 outputs a pin information setting screen to the output unit 140 (S14). At this time, since the image data for the pin information setting screen is already stored in the storage unit 150, the controller 130 reads the corresponding image data stored in the storage unit 150 and outputs it to the output unit 140. .

Next, the control unit 130 reads the signal input from the user input unit 120 to determine the region selected by the user (S15), and determines the information displayed in the determined region (ie, a reference code or a pin code). Do (S16). Then, the control unit 130 stores in the storage unit 150 in the determined order (ie, the input order) (S16).

Since information corresponding to the location of the pin information setting screen output to the output unit 140 is already stored in the storage unit 150, the control unit 130 uses the information stored in the storage unit 150 to be selected by the user. Determine the reference code and pin code.

Then, the control unit 130 reads the signal applied from the user input unit 120 and determines whether a pin information setting completion command has been input from the user input unit 120 (S17).

When a pin information setting completion command is input from the user input unit 120 (S17), the control unit 130 determines that the user's input operation for setting the pin information has been completed.

Accordingly, the controller 130 arranges the information stored in the order of determination, and then stores the arranged information in the storage unit 150 as pin information set by the user (S18).

However, if the pin information setting completion command is not input from the user input unit 120 for the set time (S17), the control unit 130 proceeds to step S15 and the input operation of the user's pin information using the pin information setting screen continues. Let it happen.

Through this operation, the user executes the pin information setting operation whenever necessary.

Next, with reference to FIGS. 3B and 4A, an operation of determining a pin code using input indirect information input by a user will be described.

As shown in FIG. 3B, when the operation state of the control unit 130 that has started the operation passes to the pin code determination operation state, the control unit 130 determines whether an indirect information input command for inputting indirect information related to the pin code has been input. Do (S22, S23). At this time, the indirect information input command may be input from the outside through the communication unit 110 or generated by an application installed inside the pin information input device 100 (for example, an application of a financial institution) and input to the control unit 130. have.

When an indirect information input command is input (S23), the control unit 130 outputs an indirect information input screen including the pin code input guide unit 121 and the indirect information input unit 122 to the output unit 140 (S23). . In this case, the arrangement of the pincode candidate group region and the reference code candidate region of the pincode guide unit 121 of the indirect information input screen output to the output unit 140 is randomly determined under the control of the controller 140. To this end, the arrangement of the pincode candidate group region and the reference code candidate region may be controlled using an arrangement region control algorithm installed in the control unit 140.

Unlike this example, when the output unit 140 does not include a part that performs the function of the input unit 120, the control unit 130 outputs an indirect information input screen including only the pin code input guide unit 121 Output to the unit 140. Accordingly, the indirect information input unit 122 is provided in the user input unit 121 or is controlled to be output to the user input unit 121.

In addition, the types and information of the pincode candidate and the reference code candidate respectively displayed in the pincode candidate group area and the reference code candidate area are already set in the storage unit 150, and the control unit 130 stores information stored in the storage unit 150. In the pincode candidate group region and the reference code candidate region, information on the pincode candidate and information on the reference code candidate are determined.

Then, the control unit 130 uses the arrangement state of the pin code candidate group region and the reference code candidate region of the pin code input guide unit 121 that are currently being output, and the pin information stored in the storage unit 150 is The input indirect information is determined and stored as set indirect information in the storage unit 150 (S24).

To this end, as already described, the control unit 130 is a pin code candidate that is located at the closest position based on the reference code candidate area having the same information as the reference code of the pin information and has the same information as the pin code among the reference code candidate areas. The location-related information of the area is determined, and the location-related information for each pincode is determined.

Next, the control unit 130 arranges the position-related information determined in order in the order of the arrangement of the pin codes determined by the user and stores it in the storage unit 150 as setting indirect information.

In this case, the control unit 130 determines the current setting indirect information for the pin information according to the arrangement order determined in the storage unit 150 or whether '0' is included.

Next, the control unit 130 reads the signal input from the indirect information input unit 122 and determines the area selected by the user to determine the selected information (eg, a number or a delete key) (S25), and then pins the determined information. The input indirect information corresponding to the code (ie, location information or location value) is stored in the storage unit 150 (S26). At this time, when the operation of the delete key is performed by the user, the last input indirect information is deleted from the storage unit 150.

Since information displayed in each area of the indirect information input unit 122 is already stored in the storage unit 150, the control unit 130 determines the information selected for the user by using the stored information of the storage unit 150. .

As already described, in order to input indirect information related to the pin code, the user checks the location of the reference code of the pin information in the pin code input guide unit 121, and is located in the nearest place based on the reference code. Check the location information or location value for the pin code (that is, the pin code of the pin information).

Then, the user sequentially inputs the identified location information or location value using the indirect information input unit 122 in the order of arrangement of each pin code.

For example, as shown in FIG. 4A, it is assumed that the pin code input guide unit 121 and the indirect information input unit 122 are output, and the pin information determined by the user is'A1234'. In addition, it is assumed that the location-related information for the pincode is location information, the arrangement order of the location information is assumed to be in the xy order, and '0' of the location information is omitted.

Therefore, in the pin information of'A1234','A' is a reference code, and '1234' is a pin code.

In this case, in order to sequentially input indirect information corresponding to each of the pin codes of '1234' in a predetermined arrangement order, the user first selects a reference code candidate area in which the reference code'A' is displayed (hereinafter,'A area' ), and searches for '1' located at the nearest location based on area A.

Therefore, in FIG. 4A, since '1' located at the nearest location with respect to area A is located directly above area A (in the y-axis direction), position information of 1 is 1 in the y-axis direction and 0 in the x-axis direction. Thus, indirect information corresponding to the pin code '1' becomes '1'.

In the case of pin code '2', '2', which is located at the nearest location based on area A, becomes 1 in the y-axis direction and 1 in the x-axis direction, and the indirect information of '2' becomes (11), and the pin code There are two '3's at the same distance with the center of area A. That is, since one is at a distance of 1 in the y-axis direction and 2 in the x-axis direction, and the other is at a distance of 2 in the y-axis direction and 1 in the x-axis direction, each indirect information about them is (12) or (21). ). Due to this, indirect information about pincode '3' is allowed for both of these (12) and (21).

Lastly, in the case of pin code '4', based on area A, '4' located in the upper right is '4' located in the nearest position, and the location information for this '4' is 1 in the y-axis direction, It is 1 in the x-axis direction. Therefore, indirect information on the pin code '4' becomes (11).

Therefore, since the overall setting indirect information for the pin code '1234' of the pin information is '1111211' or '1112111', the user must input '1111211' or '1112111' through the indirect information input unit 122 to the controller 130 ), the correct pin information is inputted.

Returning to FIG. 3B, the control unit 130 determines whether a signal is input from the indirect information input unit 122 (S27), and when there is no signal input from the indirect information input unit 122 for a set time, that is, the user's operation When there is no number input through the indirect information input unit 122, the control unit 130 compares the input indirect information and the setting indirect information stored in the storage unit 150 (S28).

When the input indirect information and the setting indirect information are the same (S28), the controller 130 determines that the input indirect information input through the indirect information input unit 122 is the same as the setting indirect information for the pin information determined by the user. do.

Therefore, the control unit 130 controls the operation of the next predetermined step (S29).

However, when the input indirect information and the setting indirect information are different from each other (S28), the controller 130 determines that the input of the indirect information corresponding to the pin information is incorrect.

Accordingly, the controller 130 outputs a pin information incorrect input notification screen indicating a pin information incorrect input state to the output unit 140 by using the data stored in the storage unit 150 (S210). For this reason, the user re-enters the correct indirect information corresponding to the set pin information after checking the output state of the screen.

The pin information input device 100 of the present example described above generates a pin code input guide unit in the control unit 130, determines indirect information about the pin information stored in the storage unit 150, and generates setting indirect information to the storage unit. Stored in 150, the input indirect information and the set indirect information are compared and determined.

However, alternatively, in an alternative example, a server may be provided that is located outside the pin information input device 100 separately from the pin information input device 100, generates and stores a pin code input guide, and stores pin information.

Accordingly, the pin information input device 100 receives data related to the corresponding pin code input guide unit from the server through the communication unit 110, outputs and stores the pin code input guide unit to the output unit, and inputs through the user input unit 120 The indirect information is transmitted to the server so that the comparison operation between input indirect information, which is indirect information input through the server, and setting indirect information can be performed, or through the operation of the described control unit 130 The comparison operation can be performed. In this case, the setting indirect information may be determined by the control unit 130 using pin information transmitted from the server or stored in the storage unit 150.

like this. When a server is provided, the control unit and the storage medium provided in the server correspond to the control unit and the storage unit of the present embodiment, respectively, to perform corresponding operations.

Instead of directly inputting the set pin information, the risk of exposing the pin information to others is greatly reduced by inputting indirect information including location-related information corresponding to the pin information.

In addition, even if at least a part of the input indirect information is exposed to nearby people, it is not possible to quickly and accurately recognize the correspondence between the exposed information and the pin information, so that the fear of exposure of the pin information is greatly reduced.

It belongs to the scope of rights.
