Paper Abstract
It is both crucial and challenging to protect biometric data used for biometric identification and authentication
systems, while keeping the systems user friendly. We study the design and analysis of biometric data protection
schemes based on fuzzy extractors. There are limitations in previous fuzzy extractors, which make them difficult
to handle continuous feature spaces, entropy estimation, and feature selection. We proposed a scheme based on
PCA features and a recently proposed fuzzy extractor for continuous domains. We conduct experiments using
the ORL face database, and analyze carefully the entropies and the resulting security of the system. We explore
and compare different ways to select and combine features, and show that randomization plays an important
role in both security, performance and cancelability. Furthermore, proposed feature selection does yield better
estimation of the final key strength.
