Generation method and apparatus for virtual keyboard used for password input

The invention discloses a generation method and apparatus for a virtual keyboard used for password input. The method comprises the steps of presetting the virtual keyboard with a 4*4 matrix, and dividing the virtual keyboard into a dynamic key region with a 4*3 matrix and a static key region with a 4*1 matrix, wherein the dynamic key region comprises ten number keys 0-9 and two space keys, and thestatic key region comprises 4 functional keys; when a password input request is received, randomly disordering key positions of the dynamic key region of the virtual keyboard last time; recording position information of the disordered keys in the dynamic region; and according to the position information of the keys in the dynamic key region and the static key region, displaying a current keyboardlayout. According to the technical scheme, the positions of the keys in the dynamic key region can be randomly disordered, so that a touch trace is prevented from being left in a fixed key position and the password input secu
