1. A computing device, comprising: a camera; an illumination device; at least one processor; and memory including instructions that, when executed by the at least one processor, cause the computing device to: activate a facial recognition mode to control access to the computing device; activate the illumination device to emit light to an area within a field of view of the camera; capture an image of the area using the camera, the image containing first image data corresponding to at least a portion of a human face; analyze the first image data to match the first image data corresponding to the at least the portion of the human face to a stored model corresponding to a face of an authorized user of the computing device; detect evidence in the first image data indicative of an artificial two dimensional representation of the human face presented to the camera, wherein the evidence is based at least in part on the light generated by the illumination device, the evidence including at least one or more specular reflections caused by the light emitted by the illumination device, a pattern of the specular reflections having a characteristic of a flat surface; and deny the access to the computing device in response to detecting that the evidence in the image indicates the artificial two dimensional representation presented to the camera.
