Key click masker and method for masking key clicks |
摘要 |
A key click masker and method for disguising key clicks protect sensitive information by randomly varying key click echo generated by a computer system. The key click masker and method disguise the actual keystrokes by generating sounds that would confuse a listener trying to determine the actual keystrokes entered by a user while the user is inputting sensitive information on an input device.
