AI Technical Summary

Benefits of technology

This new type of computer security system has two parts - one part called an encryption device or password manager (WK) with special keys for user authentication purposes while another part called a Dynamic Display Password Keyboard(WDKey). These components work together like a single unit when they are powered on again. They use this technology by randomly changing their positions within certain areas based upon how many times it was previously used before being reused. By doing these things over time, even if someone tries them repeatedly without permission from others who have access to your data, there will be no way anyone can guess what other people're trying to steal something about usable personal privacy settings such as email addresses or credit card numbers.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the security of keys found within conventional computers without compromising their ability to communicate with external sources like credit card numbers or access codes.

Embodiment Construction

[0014] As shown in Figure 1, the dynamic display password keyboard of the present invention is basically the same as the existing password input keyboard in terms of appearance and key setting, and includes a keyboard body 1 connected to an external device. Number keys 2 and function keys 3 are arranged, and the function keys include a start key, a confirmation key, a cancel key and the like.

[0015] The difference is that the keyboard body 1 is also provided with a key value display drive circuit composed of a data latch 4 and a display decoder 5, which is used to dynamically define and identify each number key 2, and the key value The display drive circuit is connected with the 8051 single-chip microcomputer 6, and the single-chip microcomputer 6 is connected with the power supply; each digital key 2 is respectively provided with an LED digital tube display unit 21 that can dynamically change and display the digital key value, and each display unit 21 is connected to the displa

Abstract

This invention discloses an encryption keyboard with dynamic display including the keyboard body linking the external device with many numbers and function keys, in which, the key value display driver circuit linking with CPU and processing dynamic definition and identification on the number keys is set. The number keys are set with display units to dynamically display number key values respectively, and the units connect the keys display driver circuits. The CPU is a SCM, and the driver circuit includes data flip-latch and display encoder. The invention uses the light digital tube to make every bit show a figure, and show different one after each restoration, thus effectively preventing stealing passwords by guessing from button positions.
