ABSTRACT:
A method and implementing system are provided for enabling a user, through the use of a specialized viewing device, to view information on a display device which is not viewable by others who are not equipped with the device. In an exemplary embodiment, selected sensitive information on a display screen is obscured from normal view. A view-enabling device is provided to authorized individuals who are able to use the device to view the sensitive information on the display device. The user looks through the view-enabling device and is able to see the otherwise obscured sensitive information. Obscuring fields are overlaid upon the sensitive information during an obscuring phase at a known overlay frequency and the view-enabling device is synchronized to effectively block-out the user's view of the display during the obscuring phase resulting in an un-obscured view of the sensitive information on the display device to the user.
