Makeup as low-tech measure against automated face recognition?

Vnity is about as old as mankind. With vanity, various ways come to change
one's appearance.

Wider lips. Narrower mouth. Wider eyes. Different shape of eyes. Name a
facial feature, there is a way to enhance or suppress it.

Face-recognition systems rely on visual appearance. They typically need
edges - edges of mouth, edges of eyes...; one popular algorithm for
indexing a face is recognizing these points and measuring their distance.
A little amount of properly applied pigment could shift these values by
couple percents.

So low-tech device a lipstick is could be a potential tool for lowering
the probability of a successful identification by face recognition. Ladies
often carry many more similar "terrorist tools" in their purses.

Opinions, comments?
