Abstract:
1. An input device for protecting input information from exposure, comprising: a user-input device receiving information including user authentication information and other different type information; a tactile-output-generator outputting a tactile signal to the user-input device; and a controller controlling output of the tactile signal, comparing received other different type information to stored other different type information, and controlling the tactile-output- generator to output the tactile signal when the received other information is the same as the stored other information, such that a next successive N input entered by the user immediately is determined as user authentication information after the tactile signal is output, wherein the received other information is determined by sensing an entry of a keystroke and the tactile signal is output during the keystroke, wherein the controller processes input values input after the N inputs as insignificant values.
