[request] Thumbprint database

[p_2001]

ok, I'm writing a program for thumbprint verification but I need a larger database than what I have.
I have googled this but found none. So here I am, asking you all if you have a database or some place where I can get them?
thanks

and why can't you add bogus data to your database to make it larger?

bogus data?
I'm talking about image database. As in images of thumbprints.
How do I generate thumbprints?

i'm working with prints that i've taken, but they aren't enough. The me I have the more I can compare.
