A system, device and method for incapacitating a keylogger. An inactivity of an input device may be detected. A flow of information from an input device to a computing device may be manipulated. A keylogger may be caused to store redundant information by causing the input device to produce redundant input. Other embodiments are described and claimed.

Static security credentials are replaced by pseudonyms and session-specific passwords to increase security associated with user login attempts, and specifically to defeat keylogging attacks. For each login event, the system generates unique, session-specific credentials by randomly replacing characters within a given username and password. The random character generation ensures that system login attempts use different combinations of characters, thereby producing a new username and password for every user session. The client side of the system requires only the capability to display an image file, with specialized software/hardware limited to the server side, thereby facilitating the use of the system by a wide range of client devices.
