Key display method of virtual keyboard

The invention relates to a button display method, in particular to a button display method of a virtual keyboard.

The keyboard is a common input device in a personal computer, and is connected to a host computer of a personal computer for the user to type a key input string. The general personal computer does not have a hardware security mechanism between the keyboard and the host computer, and the personal computer operating system does not protect the signal input by the keyboard keys. Therefore, the keyboard can be easily obtained by using the keyboard side recording technology. The signal of the button, the user will not even detect any abnormalities, and the personal account and password are stolen without knowing.

For online financial services and online transaction services, when users input strings of information such as accounts and passwords through the Internet, there is a great risk of being marginally recorded by a malicious program or a Trojan virus, resulting in a security breach. As shown in FIG. 1 , the most cost-effective solution is to avoid directly using the keyboard to input the string, and instead use the virtual keyboard 11 corresponding to the traditional QWERTY keyboard and including the plurality of virtual buttons 111 on the screen 1 of the computer, and then use The mouse pointer 12 clicks on the virtual buttons 111 to input a string of an account number and a password in the text boxes 13 and 14. The advantage of this solution is that the user does not have to prepare additional security protection hardware, such as certified card readers and authentication cards, eliminating the cost of purchasing security protection hardware.

However, after the launch of this protection method, a new malicious program further records the user's account number and password according to the virtual button position of the virtual keyboard in the screen, which further jeopardizes the security of the online financial service and the online transaction service. As shown in the "System and Method for Generating and Displaying a Keyboard with Arbitrary Configuration Buttons", the case of the Republic of China Patent Application No. 097129815 not only proposes the concept of a virtual keyboard, but also further randomly changes the position of the virtual button, making the malicious The program cannot record the correct characters. However, this method also causes the virtual keys to be randomly placed in the virtual keyboard. When the user inputs the characters, it takes time to find the virtual keys that are to be pressed by the mouse pointer, which is very inconvenient to use.

In addition, the "Digital Virtual Keyboard Password Input Method" of the Republic of China Patent Application No. 096125948 provides a dynamic virtual keyboard password input method, which combines the English character and the numeric character of the virtual keyboard. In the form of a roulette, by dynamically changing the position of the English characters and numeric characters on the virtual keyboard, it is possible to prevent the hacker from recording the user's account password according to the screen position. However, if this password input method is used in a web browser, the web browser must support instant dynamic effects, and the roulette-like virtual keyboard is still greatly different from the traditional QWERTY keyboard in the arrangement of virtual keys. It takes time to learn and adapt.

As mentioned above, in order to maintain the habit of most users on the QWERTY keyboard, it is necessary to avoid the malicious program to record the user's account and password according to the location of the virtual button, it is necessary to find a solution.

Accordingly, it is a primary object of the present invention to provide a key display method for a virtual keyboard having a QWERTY keyboard arrangement characteristic.

Therefore, the key display method of the virtual keyboard of the present invention is performed on an electronic device, and the electronic device performs the following steps: First, a processing module loads a virtual keyboard including a plurality of virtual keys from a memory module, The virtual keys are grouped into a first key group, a second key group and a third key group, wherein the first key group, the second key group and the third key group are arranged from top to bottom, wherein respectively The virtual keys for Q, W, E, R, T, Y, U, I, O, and P characters are arranged from left to right and belong to the first key group, which are respectively labeled as A, S, D, and F. The virtual keys of G, H, J, K, and L characters are arranged from left to right and belong to the second key group, which are respectively marked as virtual of Z, X, C, V, B, N, and M characters. The buttons are arranged from left to right and belong to the third group of keys. Then, the processing module randomly inserts a plurality of additional virtual keys between the virtual keys of the first key group, the second key group, and the third key group. Then, the processing module displays the virtual keyboard through a display module, and displays the first key group, the second key group, and the third key group from top to bottom. Furthermore, the processing module for an input module to virtually press the virtual keys to input a string. Further, another object of the present invention is to provide a key display method of another virtual keyboard having a QWERTY keyboard arrangement characteristic.

Therefore, the key display method of the virtual keyboard of the present invention is performed on an electronic device, and the electronic device performs the following steps: First, a processing module loads a virtual keyboard including a plurality of virtual keys from a memory module, The virtual keys are grouped into a first key group, a second key group and a third key group, wherein the first key group, the second key group and the third key group are arranged from top to bottom, wherein respectively The virtual keys for Q, W, E, R, T, Y, U, I, O, and P characters are arranged from left to right and belong to the first key group, which are respectively labeled as A, S, D, and F.
