Electronic device and keyboard device thereof and keyboard input method

Abstract

The invention discloses an electronic device and a keyboard device thereof and a keyboard input method. The method comprises the following steps that: whether a user approaches a keyboard array or not or whether a user receives the information of the keyboard array or not is detected; when a user is detected to approach the keyboard array or to receive the information of the approached keyboard array, a display keystroke value of the keyboard array is triggered, and when no user is detected to approach the keyboard array or when the user is detected not to receive the keyboard array information, the keyboard array is triggered not to display keystroke values; when the display keystroke value of the keyboard array is triggered, the keystroke value arrangement of the keyboard array is varied, or the keyboard array is triggered not to display keystroke value and the keystroke value arrangement of the keyboard array is varied after the keyboard array. Due to the adoption of the electronic device, the keyboard device and the keyboard input method, the confidentiality of the keyboard input can be effectively improved. The electronic device, the keyboard device and the keyboard input method are particularly suitable for the finance transaction application field.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to designing electronic equipment with a keyboard. Background technique [0002] A keyboard refers to a group of keys arranged to operate a machine or device, such as a typewriter or a computer keyboard, whose main function is to input data. [0003] The security performance of existing keyboards is poor. On the one hand, the key values ​​of the keyboard are limited, and there are only 10 key values ​​of numbers "0-9". Secondly, the arrangement order is fixed. The keys of the number keys are used to judge the password entered by the user. Therefore, recently, there have been technologies to prevent password theft by adding anti-peeping devices, but there are still risks. [0004] The Chinese invention patent application No. 02139757.0 published on 2003-05-07 discloses a keyboard with variable keys and its use, which includes number keys, function keys, a keyboard base, an elec...

Problems solved by technology

[0007] However, the technologies recorded in the above three patent applications have a common feature, that is, the key value of one of the layouts is usually displayed on the keyboard, and the user may not remember to change the layout before using it, so that it will be remembered by others for trial use. The previous keyboard layout; after using it, users generally will not change the keyboard layout, so it is possible to leave fingerprints and other information to be used by criminals, so the risk of password being stolen is still relatively high
