Hybrid biometric template protection: Resolving the agony of choice between bloom filters and homomorphic encryption
EAB virtual lunch talk
November 1, 2022 at 12:30-1:30pm CEST

The European Association for Biometrics (EAB) is hosting a virtual lunch talk with Amina Bassit of University of Twente about the strengths and weaknesses of Bloom filters (BFs) and homomorphic encryption (HE), prominent techniques used to design biometric template protection (BTP) schemes that aim to protect sensitive biometric information during storage and comparison.

Her key insight is to extend this theoretical investigation to iris recognition, which benefits from the alignment-free property of BFs and induces huge computational burdens in the HE-encrypted domain.

Following joint work recently published in the IET Biometrics journal, Amina will present her hybrid BTP scheme that combines BFs and HE as a solution that ensures unlinkability and high recognition accuracy while being seven times faster than the traditional HE-based approach.

Attendance is free but registration is required.
