A new design pattern of virtual keyboard is proposed in the paper, to solve the problem that the bank account and password of online banking are stolen due to the screen capture by the Trojan horse when using the traditional virtual keyboard. The main features of this design are protection of the data shown on the screen when moving and clicking the mouse, reordering the keys of virtual keyboard and higher utilization efficiency of it. The experimental results indicate that this virtual keyboard can ensure not only the security of the data, but also the high efficiency of inputting.
