Privacy-Preserving Iris Recognition
Published:
My doctoral research developed a privacy-preserving iris recognition system that performs identification directly over encrypted biometric data using fully homomorphic encryption (FHE), so that raw iris templates are never exposed during matching.
The work introduces a filter-based approach to encrypted-domain identification, addressing the performance challenges of operating over ciphertexts at scale. It was carried out in the Department of Computing at Imperial College London under the supervision of Prof. William J. Knottenbelt.
