Facial recognition is everywhere these days. Cloud servers churn through every picture uploaded to social media, phone cameras help put face
In research from a group at the Ben-Gurion University of the Negev, the team trialled whether careful makeup contouring techniques could fool a facial recognition system. There are no wild stripes or dazzle patterns here; these techniques are about natural looks and are used by makeup artists every day.
The trick is to use a surrogate facial recognition system and a picture of the person who intends to evade. Digital techniques are used to alter the person’s appearance until it fools the facial recognition system. This is then used as a guide for a makeup artist to recreate using typical contouring techniques.
The theory was tested with a two-camera system in a corridor. The individual was identified correctly in 47.57% of frames in which a face was detected when wearing no makeup. With random makeup, this dropped to 33.73%, however with the team’s intentionally-designed makeup scheme applied, the attacker was identified in just 1.22% of frames. (PDF)
