Hello,
I am using JCOP31bio and I want to make a fingerprint matching on the
card. I would like to know want type of data should I use to do the
matching(how long is the array, it is a specific format etc). I don't
have a fingerprint reader yet and I don't know what kind of data it is
sending to the card.
Well, I have not the insight, but first you generate some data which
must match by initial parsing your finger. This data consists of chunks
containing the "minutia" information, describing the fingerprint or
whatever. This data depends on the you, how you do the enrollment. Look
the init update and final methods of the OwnerBioTemplate. At
verification you only match the array(s) against the just scanned
finger. All are a part of them must match.
This is all mentioned in in the Java Card BIO API.
But, all biometric systems are insecure. At the moment biometric is only
a toy and it is easy to forge fingerprint and you cannot exchange
fingerprints very often (10 tries only) if the fingerprint is stolen
(Which is easy).
Apart from this biometric system tell too much about the owner. Beyond
the identity ypou can see what he has done (wounds on the finger), if he
has drunk (iris scans or blood) or illnesses (blood).
