1. An apparatus comprising:
an obscuring element to modify an optical transfer function of an image sensor, wherein the image sensor is to collect spatial data to control a light producing element;
a holder to support the obscuring element; and
a mounting interface disposed on the holder, wherein the mounting interface is to secure the obscuring element in front of an image sensor lens, wherein the obscuring element is to reduce an optical resolution of the image sensor to maintain privacy.
