Description

Virtual keypad security method

The present invention relates to a security method for preventing the leakage of personal information input through the virtual keypad of the output device (monitor) of the IT device to the outside, and more specifically, by displaying a plurality of mouse cursors on the virtual keypad screen. In addition, the present invention relates to a virtual keypad security method for preventing personal information input through the virtual keypad from being leaked to the outside by screen hacking or peeping.

The present invention also provides a virtual keypad security method for protecting a user's personal information input through a virtual keypad by displaying one cursor on a virtual keypad screen but recognizing information input by the user according to a separate user input value. It is about.

In the modern information society, there are many IT information devices of various forms (for example, personal computers, mobile phones, smart phones, tablet computers, financial automated terminals, automatic ticket issuing machines, access control systems, etc.). Most of these information devices have an input means for receiving information from a user, and as a means of input, a virtual keypad (virtual keyboard) displayed graphically on a screen has recently been used.

In a typical example, when an online banking using a computer requires a user to enter important personal information such as an account number, password, or security card number, a virtual keypad is displayed on a monitor screen of the user's computer. Even when online banking using a smart phone, a virtual keypad is displayed on the smart phone's touch screen to input passwords. This virtual keypad comprises a plurality of virtual keys arranged with symbols (numbers or letters or special characters). The user selects (clicks) virtual keys of the virtual keypad sequentially by dragging or touching (clicking) a pointing means or the like, so that personal information such as account number, password or security card number can be obtained even if the user does not input the keyboard keys. You can enter Methods of sequentially selecting virtual keys of the virtual keypad include a method of clicking a mouse cursor at a position of the virtual key, directly touching the virtual keys one by one, and dragging while touching the virtual keys to be selected.

IT information devices may be composed of an input device and an output device separately, or an input device and an output device may be integrated. For example, a general personal computer is composed of a keyboard device and an mouse device as input devices and a monitor as output devices. However, a smart phone, a financial automated terminal, an automatic ticket issuing machine, etc. are configured as a touch screen, and an input device for inputting information by a user and an output device for outputting a screen are integrated.

Typically pointing devices that can be used in IT information devices include mouse devices, trackballs, touch pads, tablets, joysticks, pointing sticks, fingers, and the like.

A conventional virtual keypad currently used is arranged in a position where a plurality of symbols are fixed, and when a user presses any virtual key, symbol information corresponding to the pressed virtual key is stored. Since a conventional virtual keypad is arranged in a fixed position, a user may input information by hacking the touch position from the outside. In addition, when a user clicks or touches an arbitrary virtual key of the virtual keypad by using a pointing means or the like, both the symbols arranged on the virtual keys of the virtual keypad and the position of the mouse cursor are displayed on the screen. There is a risk of personal information entered by the user through hacking or shoulder sniffing. Since the external leakage of important information input to the virtual keypad may cause serious economic loss to the user, a technique for protecting the information input to the virtual keypad needs to be developed.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art, and an object of the present invention is to select a real virtual cursor and a virtual mouse cursor on a screen when a user selects an arbitrary virtual key of a virtual keypad by using a pointing means. By displaying at the same time, to provide a virtual keypad security method that can protect the information entered by the user.

In addition, an object of the present invention is to hack or steal a screen by recognizing the user's input information by considering the position information of the mouse cursor and the user input value simultaneously when the user selects an arbitrary virtual key of the virtual keypad by using a pointing means. It is also intended to provide a virtual keypad security method that protects the information entered by the user even if the cursor is located by looking at it.

According to one or more exemplary embodiments, a virtual keypad security method includes: a first step of a controller outputting an actual mouse cursor and a virtual mouse cursor on a screen; When the pointing means moves, the control unit calculates the actual mouse cursor coordinates according to the movement path of the pointing means, displays the actual mouse cursor on the actual mouse cursor coordinates, and sets the virtual mouse cursor coordinates different from the movement path of the pointing means. Calculating and displaying the virtual mouse cursor in the virtual mouse cursor coordinates; When the selection signal is input from the pointing means, the control unit includes a third step of selecting and inputting a value corresponding to the position of the actual mouse cursor.

In addition, the virtual keypad security method according to another embodiment of the present invention, the control unit is a cursor that moves the position according to the operation of the input device and the virtual keypad including at least two or more virtual key group each of at least two or more virtual keys A first step of displaying on the screen; When a virtual key selection signal is input from an input device, the controller selects a virtual key at a position corresponding to the virtual key selection signal among virtual keys in the virtual key group where the cursor is located; The controller may include a third step of processing a symbol corresponding to the virtual key selected in the second step as a user selection symbol.

As described above, according to the present invention, since the actual mouse cursor and the virtual mouse cursor are simultaneously displayed on the virtual keypad screen, even if a third party hacks or peeks the user's input information, the user's input cannot be accurately recognized. There is an advantage to protecting information.

In addition, the virtual keypad includes a group including two or more different virtual keys, and if the cursor is located in the group, the position of the cursor is hacked by inputting one of the virtual keys of the group according to a user input value. Even if the user's input information is protected, there is an advantage.

Hereinafter, a virtual keypad security method according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

An information apparatus to which the present invention is applied includes a monitor 11 displaying a virtual keypad and a cursor image on a screen, an input device 12 for receiving a user's operation, and an output control of the virtual keypad and cursor image on a monitor 11. And a control unit 13 that receives a user input symbol from the input device 12 and stores a program for performing a virtual keypad security method applying a mouse cursor display technology and a virtual keypad processing technology according to the present invention. And a storage unit 14 for providing the user with preference information. The input device 12 includes a pointing device and a keyboard device.

In general, a virtual keypad is composed of a plurality of virtual keys, and one symbol (a number from 0 to 9, alphabet letters from a to z, or a special character) is displayed in correspondence with one virtual key. Of course, the virtual keys constituting the virtual keypad may also include a virtual key without a symbol.

[First Embodiment]

The control unit 13 according to the first embodiment of the present invention displays the actual mouse cursor and the virtual mouse cursor on the monitor 11 at the same time, and the virtual position where the actual mouse cursor is located when the user selects any virtual key (click or touch). The symbol corresponding to the key is recognized as a user selected symbol. That is, when the user selects a random virtual key, it can be seen that the actual mouse cursor and the virtual mouse cursor are located at different positions so that two or more different virtual keys are selected. However, the control unit 13 according to the present invention recognizes that one virtual key corresponding to the position of the actual mouse cursor is selected instead of the position of the virtual mouse cursor and processes the input. This user selection symbol may be stored in storage 14 or transmitted to a web server through conventional encryption and security processing.

In the first embodiment of the present invention, the input device 12 is preferably a pointing means. The monitor 11 may be implemented as a touch screen capable of both input and output, and the pointing means may be implemented as a mouse device, trackball, touch pad, tablet, joystick, pointing stick, finger, and the like.

In the specification of the first embodiment of the present invention, the actual mouse cursor is an indicator for accurately indicating the path in which the user moves the pointing means, and the virtual mouse cursor is a virtual indicator moving in a path different from the movement path of the actual pointing means. The shape and color of each mouse cursor can be variously modified, and it is preferable to create one or more virtual mouse cursors. The virtual mouse cursor may be generated at random coordinates and move in a random direction. The virtual mouse cursor may be generated at point or line symmetry coordinates of the actual mouse cursor coordinates and move while maintaining a point symmetry or line symmetry state. The virtual mouse cursor may be displayed only within the virtual keypad area or may be displayed on the full screen.

2 is a flowchart illustrating a method for securing a virtual keypad using a mouse cursor display technology according to a first embodiment of the present invention.

The controller 13 displays the virtual keypad on the screen of the monitor 11 in a conventional manner (S201).

When an event occurs by the user operating the pointing means (S202), the control unit 13 calculates the coordinates of the actual mouse cursor (S203), and compares the position of the actual mouse cursor with the virtual keypad area (S204). When the position of the actual mouse cursor enters the virtual keypad area (S204), the coordinates of the virtual mouse cursor are calculated (S205), and the actual mouse cursor is moved to the position of the actual mouse cursor while moving to the actual mouse cursor coordinates calculated in step S203. A virtual mouse cursor is generated (S206). Then, the virtual mouse cursor generated in step S206 is moved with an animation effect to the virtual mouse cursor coordinates calculated in step S205 (S207). Here, the virtual mouse cursor is one or more, step S205 is a step of calculating the coordinates of the number of the virtual mouse cursor to be created, step S206 is to create at least one virtual mouse cursor at the position of the actual mouse cursor at the same time, respectively Moving to the corresponding coordinates.

In this state, when the virtual key selection signal is input from the pointing means (S208), the virtual key selection located at the coordinates of the actual mouse cursor is recognized (S209), and a symbol corresponding to the selected virtual key is input (S210). . If the input to all the symbols is not finished (S211), the flow returns to step S202 to wait for the pointing means to be operated. Here, the input of the virtual key selection signal means that the virtual key is clicked by the pointing means or is dragged while touching the virtual key by the pointing means.

When an event occurs by the user operating the pointing means in step S202, the control unit 13 calculates the coordinates of the actual mouse cursor (S203), and compares the position of the actual mouse cursor with the virtual keypad area (S204). When the position of the actual mouse cursor moves in the virtual keypad area in step S204, the virtual mouse cursor coordinates are calculated (S212), and the actual mouse cursor and the virtual mouse cursor are moved to respective coordinates (S213).

After the step S213, if a virtual key selection signal is input from the pointing means (S208), the virtual key selection located at the coordinates of the actual mouse cursor is recognized (S209), and a symbol corresponding to the selected virtual key is input (S210). ). If the input to all the symbols is not finished (S211), the flow returns to step S202 to wait for the pointing means to be operated. When the virtual key selection signal is input from the pointing means in step S208, the controller displays on the monitor screen that both the virtual key located at the coordinates of the actual mouse cursor and the virtual key located at the coordinates of the virtual mouse cursor are selected (eg, corresponding to the corresponding key). The shape or color of the outline of the virtual keys changes, protecting user-selected information from screen hacking or third-party peeking.

When an event occurs by the user operating the pointing means in step S202, the controller 13 calculates the coordinates of the actual cursor (S203), and compares the position of the actual mouse cursor with the virtual keypad area (S204). If the position of the actual mouse cursor is outside the virtual keypad area in step S204, the actual mouse cursor is moved to the actual mouse cursor position, and the virtual mouse cursor is removed (S214). Then, the process returns to step S202.

First, as shown in (a) of FIG. 3, when the pointing means is manipulated so that the actual mouse cursor 31 enters one coordinate V1 of the virtual keypad area, the left and right sides of the virtual keypad area are determined based on the center point and the center line. The line symmetry coordinates V2, the up and down line symmetry coordinates V3, and the point symmetry coordinates V4 are respectively calculated as the coordinates of the virtual mouse cursor. Then, three virtual mouse cursors are generated at the coordinates V1 of the actual mouse cursor 31 while the actual mouse cursor 31 is moved to the actual mouse cursor coordinates V1.

As shown in FIGS. 3B and 3C, the three

virtual mouse cursors

32, 33, and 34 are animated while moving to the respective virtual mouse cursor coordinates V2, V3, and V4. Let's do it. As a result, as shown in FIG. 3D, the actual mouse cursor 31 is positioned at the actual mouse cursor coordinate V1, and the three

virtual mouse cursors

32, 33, and 34 are respectively the virtual mouse cursor coordinates V2. , V3, V4).

In the present invention, the virtual mouse cursor is generated and moved only when the actual mouse cursor is located within the virtual keypad area. However, the present invention is not limited thereto, and when the virtual keypad is displayed on the monitor screen, the actual mouse cursor and the virtual mouse cursor are displayed. You can also have mouse cursors created at the same time. In addition, in the present invention, the virtual mouse cursor coordinates are calculated to the line symmetric coordinates and the point symmetric coordinates of the actual mouse cursor, but the present invention is not limited thereto.

When the user manipulates the pointer device to move the actual mouse cursor to the coordinate V1 'as shown in FIG. 4A, the virtual mouse cursor is pre-symmetrically or point-symmetrically coordinated with the virtual mouse cursor. The coordinates V2 ', V3', and V4 'of the cursor are calculated, and the plurality of virtual mouse cursors are moved to the coordinates V2', V3 ', and V4', respectively. On the other hand, when the actual mouse cursor is moved to the coordinate (V1 "), as shown in Figure 4 (b), a plurality of virtual mouse cursors are moved to the virtual mouse cursor coordinates (V2", V3 ", V4"), respectively. Let's do it.

Second Embodiment

The control unit 13 according to the present invention displays a virtual keypad composed of a plurality of virtual keys on the monitor 11, grouping at least two or more virtual keys constituting the virtual keypad into one virtual key group. The virtual keypad includes at least two virtual key groups, and all virtual keys constituting the virtual keypad are included in one virtual key group.

When the user places the mouse cursor at an arbitrary point of the virtual key group and operates a pointing device (mouse) or a keyboard device, the control unit 13 may control among the virtual keys included in the virtual key group according to the user input value. One virtual key is selected to process the virtual key corresponding symbol as a user selected symbol.

5 is an exemplary diagram in which virtual keys of each row constituting the virtual keypad according to the second embodiment of the present invention are grouped into virtual key groups. With the mouse cursor positioned in the virtual key group of any row, when the user makes a first operation (for example, clicking the right button of the pointing device), the control unit 13 controls the first column 51 of the virtual key group. ), The virtual key corresponding symbol in the first column is recognized as a user selection symbol. When the user performs the second operation (for example, clicking the left button of the pointing device) while the mouse cursor is located at the same position, the control unit 13 determines that the virtual keys of the second column 52 of the virtual key group are assigned. Select and recognize the virtual key corresponding symbol in the second column as a user selected symbol. Finally, when the user makes a third operation (e.g., double-clicks the left button of the pointing device) while the mouse cursor is located at the same position, the controller 13 controls the third column 53 of the virtual key group. By selecting the virtual key, the virtual key corresponding symbol in the second column is recognized as the user selection symbol.

The controller 13 displays a virtual keypad composed of a plurality of virtual keys on the monitor 11 (S61). In this case, the virtual keypad includes at least two or more virtual key groups, and the virtual key group is composed of at least two or more virtual keys. Each virtual key contains a corresponding symbol. The virtual keypad includes spaces (virtual keys without symbols) between the virtual keys as shown in FIGS. 7 and 8, and spaces may be randomly arranged, and each virtual key group may include a space. It can also be done.

The virtual key group may be made based on each row of the virtual keypad as shown in FIG. 7, or may be made based on each column of the virtual keypad as shown in FIG. 8, as shown in FIG. 9. It can also include both rows and columns.

Next, the controller 13 tracks the position of the cursor according to the operation of the input apparatus (S62), and when a virtual key selection signal is input from the input apparatus (S63), the input among the virtual keys in the virtual key group where the cursor is located. A virtual key at a position corresponding to the selected virtual key selection signal is selected (S64), and the selected virtual key corresponding symbol is processed as a user selection symbol (S65). The process is repeated from step S62 until all the symbols have been entered and finished (S66).

The selection signal may be a button click signal of a mouse device, a key input signal of a keyboard device, or a signal including both button click of a mouse device and key input of a keyboard device. For example, at any point in the virtual key group, when the right button of the mouse device is clicked, the virtual key of the first position is unconditionally selected, and when the left button of the mouse device is clicked, the virtual key of the second position is unconditionally selected. If the left button of the mouse device is double-clicked, the virtual key of the third position can be unconditionally selected. As another example, no matter where the cursor is located in the virtual key group, when the first specific key of the keyboard device is clicked, the virtual key of the first position is unconditionally selected, and when the second specific key of the keyboard device is clicked, the second unconditionally second When the virtual key of the position is selected and the third specific key of the keyboard device is clicked, the virtual key of the third position may be unconditionally selected.

As another example, no matter where the cursor is located in the virtual key group, when the first specific key of the keyboard device (for example, the 'Alt' key) and the left button of the mouse device are simultaneously clicked, the virtual key of the first position is unconditionally selected. If the first specific key of the keyboard device (eg, 'Alt' key) and the right button of the mouse device are simultaneously clicked, the virtual key of the second position is unconditionally selected, and the second specific key (eg, ' If the 'Ctrl' key and the left button of the mouse device are simultaneously clicked, the virtual key of the third position is unconditionally selected, and if the second specific key of the keyboard device (for example, the 'Ctrl' key) and the right button of the mouse device are simultaneously clicked, Unconditionally select the virtual key of the fourth position.

The controller 13 tracks the position of the cursor according to the manipulation of the input device. When the cursor is located in a specific section of the virtual keypad, the controller 13 may hide the cursor without displaying the cursor.

When the virtual key selection signal is input, the control unit displays on the monitor screen that all virtual keys located in the virtual key group are all selected (for example, the shape or color of the outline of the corresponding virtual keys is changed), or the virtual key where the cursor is located is displayed. Mark it as selected (even if a virtual key from another location in the virtual key group is selected) to protect the user's selected information from screen hacking or third-party peeking.

The technical spirit of the present invention has been described above with reference to the accompanying drawings, but this is by way of example only for describing the best embodiment of the present invention and not for limiting the present invention. In addition, it is obvious that any person skilled in the art can make various modifications and imitations without departing from the scope of the technical idea of the present invention.
