摘要

A display filter for preventing the display of sensitive information on the display of a processing system. The display filter comprises: 1) a data processor; 2) a memory for storing user application programs executable by the data processor and user documents associated with the user application programs; and 3) a display filter application program stored in the memory and executable by the data processor. The data processor, under control of the display filter application program, identifies sensitive information in a first selected user document and causes the first selected user document to be displayed on the display with the sensitive information obscured.
