The fuzzy vault is an error tolerant authentication method that ensures the privacy of the stored reference data. Several publications have proposed the application of the fuzzy vault to fingerprints, but the results of subsequent analyses indicate that a single finger does not contain sufficient information for a secure implementation.

This paper presents a comparative study on fingerprint recognition systems. The goal of this study was to investigate the capability characteristics of biometric systems regarding integration of biometric features in personnel documents such as ID cards and Visa application documents. Thus the designed test has the focus on performance testing of selected(More)

We investigate the security of a privacy enhancing technique for fingerprint authentication known as fuzzy fingerprint vault. This technique is based on the fuzzy vault of Jules and Sudan, a scheme that allows error tolerant authentication, while preserving the privacy of the reference data. We explore if and under what circumstances a secure fuzzy(More)
