Hi,

In a bid to simplify patient identification, we here in India are adding
fingerprint information about the patient when getting registered. The idea
in the Ministry's technical support group is that we can have an incoming
patient at the hospital, keep his/her finger on a scanner and he would
automatically be identified and his summary printed-out alongwith his latest
appointment date.

Such a project requires 1-n identification based on the patient's
fingerprint. I have been testing a few SDKs (Java, C++ and C#) and most of
them seem to only allow 1-1 matching. Others, I have modified for 1-n
identification take exponentially more time as the number of fingerprints
are increasing (4 users = 41 secs; 6 users = 179 secs ). What is normally
done is that the user puts a card/password and then the authentication
software performs a 1-1 match on the given fingerprint with the one stored
in the database. But what we want is a identification system, rather than an
authentication system based on fingerprints.

I would like to get your ideas on how to solve this problem or if any
implementation is already using such a system. If you know of any existing
SDKs that can quickly do person identification based on fingerprints. Any
comments would be appreciated.
