Graphics keyboard based security input method for computer information

Abstract

A safe input method of computer information based on pattern keyboard includes preconfirming input character set, confirming input boundary region, plotting each character in pattern mode and displaying it on said region, storing relation of each character to plotting and position in boundary region into computer storage, intercepting click position of mouse by '' Hook '' program embedded in user program when user clicks any point on said region , indexing out position information stored in said storage and outputting its corresponding character as user input.

Description

technical field [0001] The present invention relates to computer security technology, more specifically, relates to a computer information security input method based on a graphic keyboard. Background technique [0002] Computer applications are inseparable from input and output. Among them, keyboard input is the most commonly used and most convenient means of information input, especially for inputting a small amount of numbers and character information. Although the conventional keyboard input of numbers and letters is convenient, it is still safe. For example, stealing keyboard input is a function of popular Trojan horse programs. Anyone with low computer skills and no programming and development capabilities can use and spread Trojan horse programs. Most of the transmission from these people makes it possible that when numbers or characters are input through the keyboard, the input numbers and characters may be stolen by a computer-infected Trojan horse program, so that ...
