[clug] Biometrics and Linux

[Andrew Pollock]

Hi,

I'm looking at developing an application, and I'd like use fingerprints for
authenticating users of the application.

A while ago, I did a lot of research into fingerprint readers, but didn't
find any that openly claimed Linux support.

The other thing is, does anyone know how they work? Are the identifying
features of the fingerprints stored in the reader itself, or does it just
spit out the equivalent of a checksum to the application for
comparison/verification?

Thanks for any advice.

Andrew
