Story: Scientists pore over biometric-spoofing tests

In general, any type of multi-biometric authentication can reduce the possibility of fraud, which is why you're seeing so many finger-face combinations these days. However, once you've crossed that hurdle you need to deal with the accuracy of the various biometrics selected, and figure out how best to use the biometrics. For example, in a two-biometric system using 1:n searches, do you compare the search case against the full databases for both biometrics, or do you use one biometric to create a candidate list, then only run the candidate list through the second biometric? These are the items that need to be worked out in each individual system.
