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.
