Project: Cancelable Biometric Authentication
Supervisor: Rei Safavi-Naini, Luke McAven

Biometric based authentication can provide strong security guarantee about the identity
of users. Security of biometric data is particularly important as compromise if the data
will be permanent. Cancelable biometrics store a non-invertible transformed version of
the biometric data and so if the storage is compromised the biometric data remains safe.
Cancelable biometric also allow higher level of privacy by allowing many template for
the same biometric data. We consider a key-dependent geometric transformation applied
to features extracted from a fingerprint to generate a key dependent cancelable template
for the fingerprint. Performance of the system is measured in terms of false acceptance.

The project is the continuation of an exiting system [1] and will follow and extend that
work. The goal of the project is to design suitable and measure its performance. The
definitions and framework in [1] will be used for evaluation.

The outcome of this project will be (i) a new transformation and the corresponding
matching algorithm, (ii) a report describing the new system with intuitive justification of
why the system is expected to work, and (iii) an implementation and performance
analysis of the system.
