is there a way to find a fingerprint without look all the table?

The way that I'm doing is like so:

I have to look all table in order to check if a stored fingerprint matches to a new one.

I'm looking for a way to generate some hashcode according to fingerprint's template and check it directly.

But I realized that for each time that it's generated a array. This one has a different size foreach time you put you finger on the device.

How would I sove it?

Dear Sr,

It is not possible to do that because the template is diferent each time you extract it. However the AFIS classifies the digital as Left Loop, Right Loop and others, so you can use this to index your DB and make the search faster.
