Abstract
Encrypting keystroke data on a computing device involves receiving a key identifier (ID) from a keyboard device, creating a keystroke cipher segment comprising a primary authentication code and the key ID, and encrypting the keystroke cipher segment to generate an encrypted keystroke cipher segment. The keystroke cipher segment is included within a keystroke message and transmitted from the keyboard device driver to a window event handler via an input/output (I/O) message channel native to an operating system running on the computing device. The encrypted keystroke cipher segment is decrypted to identify the key ID, which is transmitted to a first application for further processing.
