a transparent display for viewing an object through the transparent display;
a watermarking engine configured to display a watermark on the transparent display, wherein location of the watermark indicates a current timestamp, wherein the watermarking engine is configured to change the display on the transparent display, wherein changing the display includes displaying text on the transparent display that diminishes ability to view the object through the transparent display; and
