Abstract
A system and corresponding method for providing security against unwanted viewing of information being displayed on a video terminal of a computer workstation, the computer workstation including an input device such as a keyboard, the system including: a camera, responsive to the presence of any user of the computer workstation, the camera for providing from time to time a camera image suitable for indicating whether at the time a user is viewing the video terminal; a guard module, hosted by the workstation, responsive to the camera image, and further responsive to a notice of activity on an input device, the notice provided by the operating system of the workstation, for providing in pre-determined cases a command to the operating system to open a covering window and to display on the video terminal the covering window as the active window, the covering window of sufficient size to cover substantially all of the information bearing regions being displayed on the video terminal; wherein the pre-determined cases include a case in which the camera image indicates that no user is present at the workstation and there is no activity on any input device, and a case in which the camera image indicates that although a user is present at the workstation, the user is not looking at the video terminal, such as when a user has turned away from the video terminal to talk to a passerby, and there is no input activity.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
