Password security input system and password security input method using shift value of password key

Abstract

The present invention relates to a password security input system which performs authentication through input of a security password key which is obtained by applying a shift value to an actual password key, and a password security input method thereof. According to the present invention, a password security input system is configured with a user terminal comprising: a password setting module for receiving and storing an actual password which is inputted during the initial setting by a user; an input window generating module for generating an input window in which key buttons are randomly disposed in every instance where a password is inputted; a password input module for receiving keys of a security password which are position-changed by applying the same shift distance to the key positions of the actual password in the input window displayed on a screen; and a password authentication module for comparing a key shift value of the pre-stored actual password with a key shift value of a security password inputted by a user on the basis of the input window, and determining that password authentication is in success when the two key shift values are the same. According to the present invention, even if a security password is exposed to a third person, the user can maintain the actual password with a sound mind.
