Description

System for generating dynamic virtual keyboards

The present invention relates to a system for a virtual keyboard, and more particularly to a system for generating a dynamic virtual keyboard.

The keyboard is a common input device. Computers, mobile phones, cash registers, cash machines, etc. all need to use the keyboard, and the development of the keyboard has evolved from a physical keyboard to a virtual keyboard, which can be clicked on the screen or from the screen. Click on the desired character directly.

However, in the face of an open Internet, there are people who are interested in implanting malicious programs to steal personal account passwords. Therefore, the security of financial transactions or online services on the Internet is the object of concern to users. The currently known protection measures only change the position of the virtual button on the virtual keyboard to avoid the position of the virtual keyboard being recorded by the side recording program. However, when the user inputs the information such as the account password, the signal is transmitted back to the bank server. It may also be intercepted.

The inventor, because of this, in the spirit of active invention, think of a system that generates a dynamic virtual keyboard, preventing the side recording program from recording users. In addition, the backhaul signal between the user end and the bank server is also prevented from being stolen.

The main purpose of the present invention is to provide a virtual keyboard that can randomly change the position of a virtual key and randomly change the font of a character, so as to prevent a malicious program from recording the correct character on the side of the electronic device, and the virtual button corresponds to a different corresponding code. In order to prevent the malicious program from intercepting the signal of the correct character in the process of returning the signal, the double protection method can provide the user with higher security to avoid being stolen by a personal account or password.

To achieve the above object, the present invention provides a system for generating a dynamic virtual keyboard, comprising: a backend server comprising a processor and a memory, the processor generating a virtual keyboard having a randomly transformed position a plurality of virtual buttons, each of the plurality of virtual buttons having a corresponding code, the memory storing the virtual keyboard and the corresponding code; and at least one electronic device connecting the backend server through an internet, the at least An electronic device includes a display screen that displays the virtual keyboard.

The above summary and the following detailed description are exemplary in order to further illustrate the scope of the invention. Other objects and advantages of the present invention will be described in the following description and drawings.

FIG. 5 is a dynamic virtual keyboard according to a fourth embodiment of the present invention.

First, referring to FIG. 1 and FIG. 2, it is a schematic diagram of a system for generating a dynamic virtual keyboard according to the present invention and a dynamic virtual keyboard according to a first embodiment of the present invention. As shown, the system 1 includes a backend server 2 including a processor 21 and a memory 22. The processor 21 generates a virtual keyboard 23 having a plurality of virtual virtualized positions. The memory button 22 stores the virtual keyboard 23 and the corresponding code. And at least one electronic device 3 is connected to the backend server 2 via an internetwork 4, the at least one electronic device 3 includes a display screen 31, and the display screen 31 displays the virtual keyboard 23.

In a first example, the electronic device 3 can further include a mouse. When the user logs in the account password on the electronic device 3, the processor 21 of the backend server 2 generates a virtual keyboard 23 and Randomly transforming the positions of the plurality of virtual keys 24 and randomly generating interference characters such as a deformed font, a skewed font, etc., and the plurality of virtual keys 24 are all configured with a corresponding code as shown in the corresponding code (1) of Table 1, and The plurality of virtual buttons 24 are displayed on the display screen 31 of the electronic device 3, and the user then uses the slide After the mouse selects the plurality of virtual buttons 24 in the virtual keyboard 23 on the display screen 31, the electronic device 3 returns the corresponding code of the plurality of virtual buttons 24 to the backend server 2, the process The device 21 compares the corresponding code returned by the electronic device 3 with the corresponding code stored in the memory 22 to confirm the plurality of virtual keys 24 selected by the user.

In a second example, the display screen 31 is a touch display screen 31, which allows the user to directly select the plurality of virtual keys 24 in the virtual keyboard 23 on the touch display screen 31. The same as the first example, it will not be described again.

Please refer to FIG. 3, FIG. 4 and FIG. 5, which are dynamic virtual keyboards of a second, a third, and a fourth embodiment of the present invention. As shown in the figure, it can be seen that the virtual keyboard 23 has a plurality of virtual buttons 24 with random conversion positions, and the corresponding codes of the corresponding codes (2), (3), and (4) shown in Table 1 are respectively arranged, but are not limited to the table. 1, the user can click the Caps Lock button to convert the case of the letter. In a third example, when a user logs in an account password on the electronic device 3, the processor 21 of the backend server 2 generates a virtual keyboard 23, and randomly converts the plurality of virtual buttons 24. The position and the random transformation character font are as shown in FIG. 3 and the corresponding code of the corresponding code (2) of Table 1 is configured, and the plurality of virtual keys 24 are displayed on the display screen 31 of the electronic device 3 as shown in FIG. The user selects the XYZ of the virtual button 24 on the display screen 31, and the electronic device 3 returns the corresponding code Q21 to the backend server 2, and the processor 21 returns the same to the electronic device 3. Corresponding code and the corresponding code stored in the memory 22 are used to confirm the XYZ of the plurality of virtual keys 24 selected by the user. Randomly transforming the plurality of virtual buttons The position of the key 24, the randomly transformed character font, and each of the plurality of virtual keys 24 are configured with different corresponding codes, and the user does not have to worry about the malicious program to record the position of the virtual button on the electronic device and steal the account. The password does not have to worry about the password being intercepted by the malicious program when the signal is returned.

In a fourth example, when multiple people need to input an account password in different places, the processor 21 of the backend server 2 generates a plurality of the virtual keyboards 23 and allocates them to the plurality of electronic devices 3, and more The virtual key The disk 23 has a plurality of virtual buttons 24 at different positions, and each of the plurality of virtual buttons 24 is configured with a different corresponding code. The memory 22 stores a plurality of the virtual keyboard 23 and a plurality of the corresponding codes, and the plurality of The display screen 31 of the electronic device 3 simultaneously displays the plurality of virtual buttons 24 at different positions, and the remaining systems are the same as the third example, and details are not described herein.

In a fifth example, when the user inputs the account password multiple times, the processor 21 of the backend server 2 generates a virtual keyboard 23 each time, and each of the virtual keyboards 23 has a plurality of different positions. Each of the plurality of virtual buttons 24 is configured with a different corresponding code. The memory 22 stores the virtual keyboard 23 and the corresponding code each time, and the display screen 31 of the electronic device 3 meets each time. The plurality of virtual keys 24 in different positions are displayed, and the remaining systems are the same as the third example, and details are not described herein.

The above-mentioned embodiments are merely examples for convenience of description, and the scope of the claims is intended to be limited to the above embodiments.
