Polish designer Ewa Nowak has developed a mask that makes the wearer's face undetectable to facial recognition algorithms used in public surveillance cameras. Nowak designed the Incognito mask in an attempt to reclaim the privacy and anonymity that they feel has been lost to face-detecting cameras installed in public spaces. Described by the designer as "face jewellery", the main structure of the mask-like accessory consists of a long piece of brass that has been shaped to fit the contours of the face, curving behind the ears like a pair of glasses. It features three prominent elements that work together to make the wearer's face "unrecognisable" to cameras. These are two brass circles that sit below the wearer's eyes, and a rectangular element positioned between the eyes.
