Abstract
A method of automated password authentication by pattern matching regions of screen pixels against a repository of previously captured regions, and submitting a username and a password stored with the regions of the screen pixels for authentication includes triggering an autorunnable application to startup by inserting a memory stick by a user, challenging the user for a master password to access an encrypted database held on the memory stick, running the autorunnable application as a background task following a successful authorization of the user, and checking whether the user has triggered the autorunnable application by a pre-defined key sequence. If the user has triggered the autorunnable application, then the method proceeds with prompting the user to highlight at least one rectangle around a text or an image which uniquely identifies a login panel, capturing a username and a password when entered by the user, and returning the autorunnable application to a background task. If the user has not triggered the autorunnable application, then the method proceeds with monitoring a screen buffer for a matching signature based on the rectangle drawn by the user.
