Makeup
Obscuration
L.E.D.s
Hyperface
Makeup, especially that which covers or obscures lines of the face or eyes that facial recognition software relies upon to create a profile, can cause disruptions in the software's ability to read your features. Dark eyeshadow, asymmetric designs, or anything that strongly obscures the center of the face can render facial recognition software unreliable.
Physical obscuration of the face can also strongly disrupt facial recognition software. Obscuring lines of the face and eyes especially will prevent software from making a profile.
L.E.D. lights will also strongly disrup facial recognition software by creating a glare against cameras. Directive L.E.D.s work best, but soft L.E.D.s around the eyes, lips, and cheeks will also work. Many people will design glasses that shine L.E.D.s outward to specifically prevent software from creating or matching a profile.
Hyperface is a specific pattern created by Berlin-based artist Adam Harvey. This pattern works not by preventing software from making a profile, but by providing it with so many false profiles it becomes overwhelmed. Hyperface can be incorporated into makeup and textiles to render facial recognition software as universally unreliable due to a large degree of false profiles.
