Embodiments are directed to an optical privatizing device (100), system and methods of use. The device includes a removable frame (101) removably attachable to a sensor housing (1A). A device includes a blurring lens (130) coupled to the removable frame (101) and configured to optically modify light passing to a depth sensor wherein the optical modified light has a privatizing blur level to neutralize a profile of an object sensed by the depth sensor within a working volume of the depth sensor to an unidentifiable state while maintaining a depth parameter sensed by the depth sensor.
