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.

Abstract
An input device and method for protecting input information from exposure, in which the time of input of information is determined using a tactile output to protect the input information from being exposed. The input device for protecting input information from exposure includes a user-input module for receiving predetermined input information from a user, a control module for setting the information inputted in association with a tactile signal among the input information as user-input information, and a tactile-output-generation module for generating and providing the tactile signal to the user-input module under the control of the control module.
