Cancelable biometrics are a group of techniques to transform the input
biometric to an irreversible feature intentionally using a transformation
function and usually a key in order to provide security and privacy in
biometric recognition systems. This transformation is repeatable enabling
subsequent biometric comparisons. This paper is introducing a new idea to
exploit as a transformation function for cancelable biometrics aimed at
protecting the templates against iterative optimization attacks. Our proposed
scheme is based on time-varying keys (random biometrics in …
