Cancelable biometrics refers to a group of techniques in which the biometric inputs are transformed intentionally using a key before processing or storage. This transformation is repeatable enabling subsequent biometric comparisons. This paper introduces a new scheme for cancelable biometrics aimed at protecting the templates against potential attacks, applicable to any biometric-based recognition system. Our proposed scheme is based on time-varying keys obtained from morphing random biometric…

OTB-morph: One-Time Biometrics via Morphing

A new idea to exploit as a transformation function for cancelable biometrics aimed at protecting the templates against iterative optimization attacks is introduced, based on time-varying keys and morphing transformations.

Toward Face Biometric De-identification using Adversarial Examples

It is discovered, unlike previous claims in the literature, that it is not easy to get a high protection success rate (suppressing identification rate) with imperceptible adversarial perturbation to the human visual system.

Cracking Cancelable Fingerprint Template of Ratha

It is revealed in this paper that the form of the transforms and the parameters chosen in his implementation weaken the many-to-one property, which results in the possible recovery of original minutiae from one transformed template.

This paper demonstrates several methods to generate multiple cancelable identifiers from fingerprint images to overcome privacy concerns and concludes that feature-level cancelable biometric construction is practicable in large biometric deployments.

Generation of Cancelable Iris Templates via Randomized Bit Sampling

This paper has generated cancelable IrisCode features, coined as locality sampled code (LSC), which simultaneously provides strong security guarantees and satisfactory system performance, and formally analyzed the security guarantees of non-invertibility, revocability, and unlinkability.
