Abstract
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.
