A view restrictor is employed to ensure that private information can only be viewed on an interactive display by a privileged user but not by non-privileged users. By detecting the location and orientation of the view restrictor on the display surface, a private portion of the display surface can be determined. The private portion is not visible to non-privileged users. The private information is then displayed to a privileged user at this private portion, and the view restrictor blocks non-privileged user(s) from viewing the private information. The interactive display detects removal of the view restrictor from the display surface, and interrupts display of the private information. In another embodiment, the private information is obfuscated so that it can be viewed only by a privileged viewer through a view revealer that includes a color filter. The private information may be either a graphic image or text.
