Number of biometric samples required to form an exhaustive set of fingerprint hashes?
Slight variations in the sample produce different hash values of the sample data. The answer linked below indicates that enough different samples might produce an exhaustive set of hash values.
The following fingerprint hash system was proposed: Fingerprint hash I am trying to determine whether or not the number of samples required is infeasibly large or small enough to be feasible.
Hashing mathematical models of a fingerprint patterns seems to provide a sufficient solution. A mathematical model of a fingerprint would focus only on the key distinguishing features of the fingerprint pattern and thus ignore other differences between a pair of images.
