A Deeper Dive into the Irreversibility of PolyProtect: Making Protected Face Templates Harder to Invert
Researchers strengthen PolyProtect's resistance to template-inversion attacks on face embeddings — relevant for organisations relying on biometric authentication under GDPR's special-category-data rules.

arXiv:2605.03857v2 Announce Type: replace-cross Abstract: This work presents a deeper analysis of the "irreversibility" property of PolyProtect, a biometric template protection method initially proposed for securing face embeddings. PolyProtect transforms embeddings into protected templates via multivariate polynomials, whose coefficients and exponents are distinct for each subject enrolled in the face recognition system. A polynomial is applied to consecutive sets of elements from a given embe
Editorial Analysis
Enterprises deploying facial recognition must prove template irreversibility under GDPR; this work benchmarks a key protection scheme against stronger adversaries.
Review biometric template protection implementations against the updated inversion methodology to confirm GDPR-compliant irreversibility.
