Protecting hybrid biometric templates: Solving the agony of choosing between bloom filters and homomorphic encryption
EAB Virtual Lunch
November 1, 2022 from 12:30 p.m. to 1:30 p.m. CEST

The European Association for Biometrics (eBike) hosts a virtual lunch-debate with Amina Bassit from the University of Twente on the strengths and weaknesses of Bloom Filters (BF) and Homomorphic Encryption (HE), leading techniques used to design pattern protection schemes (BTP) that aim to protect sensitive biometric data. information during storage and comparison.

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

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

Participation is free but registration is mandatory.
