‘The glasses, recently described in this paper and featured on the excellent blog Prosthetic Knowledge, contain patterns on the front of the frames that obscure the identity of the wearer to facial recognition algorithms. For example, one of the researchers who developed the glasses, a white male, passed for actress Milla Jovovich. His colleague, a South-Asian female, successfully impersonated a Middle Eastern male.

The glasses were developed to mislead facial recognition programs that use neural networks (a form of advanced machine learning that mimics the human brain), said researcher and co-creator Mahmood Sharif.
