Fingerprints (was: Re: biometrics)

[Arnold G. Reinhold]

There is some interesting information at http://www.finger-scan.com/ 
They make the point that finger scanning differs from finger printing 
in that what is stored is a set of recognition parameters much 
smaller than a complete fingerprint image.  So there is no need for a 
lengthily process to acquire an initial image. Presumably this also 
makes finger scan data proprietary, since each vendor will use a 
different recognition algorithm.

Finger Scan also has a page on accuracy where they debunk other 
vendors' claims of 0.01% false reject/ 0.001% false accept, but tell 
you to e-mail them for the real numbers.
