This system seems explicitly designed to confuse the most common face detector, the Viola-Jones system, which is the basis for the face detection you can find in a lot of cameras these days. Note that detection (is there a face in the picture?) is a different task than recognition (whose face is it?). It will probably make face recognition harder as well, but so would wearing sunglasses, a beard or hair over your face.
