Abstract

The invention discloses an on-screen keyboard input system for preventing Trojan programs and a method thereof, which aims to solve the problem of keystroke logging easily by the Trojan programs when inputting confidential and private data. By allocating with random numbers and performing the process of hide display via keys of the on-screen keyboard, the method is used to prevent Trojan programs with functions of logging keystrokes and image acquisition.

Description

technical field [0001] The present invention relates to an on-screen keyboard system and its method, in particular to an on-screen keyboard input system and its method capable of preventing Trojan horse programs from skimming sensitive data. Background technique [0002] In recent years, with the vigorous development of the computer industry and the Internet, digitization has become an inevitable trend, such as e-mail, electronic document systems, and electronic administrative systems. Therefore, how to avoid sensitive personal data such as account numbers and passwords from being recorded by Trojan horse programs has become a problem that cannot be ignored. [0003] Generally speaking, Trojan horse programs are divided into two types according to their functions. The first type is a Trojan horse program with a keystroke recording function, which can record the characters typed by a user on a physical keyboard; The Trojan horse program with the capture function can capture ...
