Anti facial recognition systems
In January 2013 Japanese researchers from the National Institute of Informatics created 'privacy visor' glasses that uses nearly infrared light to make the face underneath it unrecognizable to face recognition software.[68] The latest version uses a titanium frame, light-reflective material and a mask which uses angles and patterns to disrupt facial recognition technology through both absorbing and bouncing back light sources.[69][70][71][72] In December 2016 a form of anti-CCTV and facial recognition sunglasses called 'reflectacles' were invented by a custom-spectacle-craftsmen based in Chicago named Scott Urban.[73] They reflect infrared and, optionally, visible light which makes the users face a white blur to cameras.[74]
Another method to protect from facial recognition systems are specific haircuts and make-up patterns that prevent the used algorithms to detect a face.[75]
