Towards Protecting Face Embeddings in Mobile Face Verification Scenarios. (arXiv:2110.00434v3 [cs.CV] UPDATED)

This paper proposes PolyProtect, a method for protecting the sensitive face
embeddings that are used to represent people's faces in neural-network-based
face verification systems. PolyProtect transforms a face embedding to a more
secure template, using a mapping based on multivariate polynomials
parameterised by user-specific coefficients and exponents. In this work,
PolyProtect is evaluated on two open-source face recognition systems in a
cooperative-user mobile face verification context, under the toughest threat
model that assumes a fully-informed attacker with complete knowledge of …
