Abstract
The present disclosure discloses a pattern input apparatus and a pattern input method for user authentication. According to the present disclosure, differently from the pattern function of the related art, the user does not directly input a pattern through a pattern lock interface, but inputs the pattern using a virtual manipulation interface which is separately provided. Therefore, it is strong to a smudge attack. The pattern input method of the present disclosure includes providing a virtual manipulation interface to input the pattern on the screen of the device to the user, separately from a pattern lock interface; and receiving the pattern through the virtual manipulation interface.
