Abstract

Helper data systems mitigate the risk that biometric templates are stolen from
a biometric data base. Yet, current systems face the drawback that strong Error
Correction is needed in order to mitigate variations in the measured biometric
during verification. Error correction codes are not always attractive, as these may
severely reduce the effective entropy extracted from the biometric. We study an
alternative, namely to check the (set of) most likely errors, based on a posterior
side information, using soft decision during verification.
