Authentication with biometrics
I'm working on a project where I use fingerprints for authentication on the internet instead of passwords. This is what happens: Someone accesses my web-site. To log on they put their finger on a fingerprint-pad and then some pre-installed software sends the whole fingerprint to my server for authentication. The transmission is encrypted using PKI. If OK, they gain access to an extranet.
Many applications use biometrics for authentication, but I think mine's a little different. Other apps map the fingerprint against a password on the client, and then sends the password for authentication on the server. But I use a sentralized database of fingerprints.
What I need to know is if there are other solutions similar to mine that you know about. I've searched the net and haven't found anything (just the apps that map to passwords). Perhaps some of you can help me out? Thanks!
