Abstract
This invention is a wearable device and method for disrupting unwelcome photography by a proximal imaging device in order to protect a person's privacy. This invention can be embodied in a device worn by the person whose privacy is to be protected comprising: a wearable light source; an ambient light sensor; an inbound light guide that harvests light from an ambient light source; a data processing unit that selects the use of light from the wearable light source, from the ambient light source, or from both the wearable light source and the ambient light source to disrupt unwelcome photography; and an outbound light guide that directs light from the wearable light source, from the ambient light source, or from both the wearable light source and the ambient light source toward the proximal imaging device in order to disrupt unwelcome photography.
