Cancellable biometrics and annotations on BioHash
Published 2008“…However, this raises the possibility of two identity theft scenarios: (i) stolen-biometrics, in which an impostor possesses intercepted biometric data of sufficient high quality to be considered genuine and (ii) stolen-token, in which an impostor has access to the genuine token and used by the impostor to claim as the genuine user. …”

Generation of replaceable cryptographic keys from dynamic handwritten signatures
Published 2006“…Our experiments indicate encouraging result especially for skilled and random forgery whereby the equal error rates are < 6.7% and similar to 0% respectively, indicating that the keys generated are sufficiently distinguishable from impostor keys. …”

Feature fusion using a modified genetic algorithm for face and signature recognition system
Published 2015“…This thesis focuses on the development of feature level fusion of bimodal biometrics system for face and dynamic signature recognition system The modalities of biometric are used due to the ability to avoid spoof attack since it is difficult for impostor to imitate two different characteristics (behaviour and physical) at the same time. …”

Fusion of license plate and face recognition for secure parking / Siti Salwa Md Noor
Published 2013“…Additionally, the algorithms developed in this study are also validated and verified based on three performance measures namely genuine acceptance rate (GAR) for plate as 96% based on registered car plate during exit whilst face GAR of 80% for registered owner or user to be allowed to exit. As for impostors, the rejection rate (IRR) calculated is 100% as indicator of the specificity of impostors as well as prohibiting unregistered owner or user to proceed and exit.…”
