Method and Apparatus for Securing Input of Information via Software Keyboards

摘要

Data entry using a software keyboard such as a touchscreen keyboard is secured by varying key sizes in the keyboard from key to key and from software keyboard configuration to software keyboard configuration, decoupling display locations from keys. Multiple software keyboard configurations are generated, each having different sets of key sizes. The keyboard configuration may be changed with each keystroke, or may be changed for each prompted entry including multiple keystrokes.
