Fast identification (maybe fingerprint) using Ruby?

Rails
1

Hi guys

The project I am working on has a webpage where users register. We
want to be able to keep track of how many times each user visits our
premises. Because it is a somewhat “private” business we are unable to
use some kind of membership card or similar. The identification also
has to be fast because in one night there can be up to 300 guests of
which maybe 200 would have to be identified.

The “easiest” solution to this would be a fingerprint identification.
Alternatively maybe some kind of face detection software. The database
with the user data is a standard mysql database. Ideally I would be
able to write something in Ruby but I’m not sure if drivers exist,
etc.

Throw some ideas over and tell me about any experience you might have
about something similar.

Thanks for your help.

Personally, I’d far more likely “give you the finger” before giving you
my fingerprint. But, that’s just me… Same goes for any sort of
biometric authentication.

The problem with biometrics is that once your identity escapes your
control there is no reasonable way to invalidate that. Fingerprints
cannot be revoked (short of cutting off your fingers).

Stefano, you might want to take a look at the following:
