Abstract
This invention relates to the veracity of information displayed to a user of a computer, and information provided to a computer by human input devices such as mice and keyboards. A digital video guard (DVG) device is a peripheral that is retrofitted to commodity computer devices. The DVG resides in-line with a digital display and enables secure end-to-end interactions between a user and a displayed (usually remote) application. In-band signalling within the digital video stream is used to carry encrypted information from a local or remote source, over untrusted network infrastructure through the digital video guard device to a user. The DVG decrypts and verifies the integrity of the digital video. The integrity of the displayed information is indicated by a trusted LED on the DVG hardware. Portions of the video signal may be designated as trusted, if the received data has been encrypted, signed, or labelled as trustworthy.
